Description
BACKGROUND
[0001] Cancer is a leading cause of death worldwide, accounting for 7.6
billion deaths (around 13% of all deaths) in 2008. Lung, stomach, liver,
colon, and breast cancer cause the most cancer deaths each year,
according to the World Health Organization. Cancer is the second leading
cause of death in the United States, exceeded only by heart disease. In
2008, more than 565,000 people died of cancer, and more than 1.48 million
people had a diagnosis of cancer, according to the United States Cancer
Statistics: 1999-2008 Incidence and Mortality Web-based Report. The cost
of cancer extends beyond the number of lives lost and new diagnoses each
year. The financial costs of cancer also are overwhelming. According to
the National Institutes of Health, cancer cost the United States an
estimated $263.8 billion in medical costs and lost productivity in 2010.
(See, www.cdc.gov/chronicdisease/resources/publications/AAG/dcpc.htm.)
SUMMARY
[0002] The present invention relates in general to methods and
compositions for the treatment of cancer, in some embodiments for the
treatment of cancers of epithelial cell origin. Improved treatment
methods and regimens described herein are the product of a novel and
comprehensive approach to the development of individualized treatments
for cancer. The approach to treatment recognizes that cancer growth and
metastasis depends on unchecked cellular processes, in particular
angiogenesis, and simultaneously the activation of multiple metabolic and
signaling pathways in the patient. Pathways that in a normal individual
would suppress, or at least not support, cancer growth are inactive,
blocked or attenuated in a cancer patient; likewise, pathways that are
cancer-supportive, which are held in check or counterbalanced in a normal
individual, are amplified in a cancer patient. In some embodiments, an
object of the therapeutic approach of the present invention is to inhibit
or attenuate angiogenesis as well as to rebalance as many of the
metabolic, intercellular signaling, and intracellular signaling pathways
that are detected or suspected to be contributing to the survival or
growth of the cancer.
[0003] In some particular embodiments, objects of provided treatment
protocols described herein are to achieve one or more of the following:
[0004] blocking, interrupting, or attenuating tumor angiogenesis (i.e.,
the formation and development of the vasculature that tumors need in
order to thrive and progress) or pathways that support angiogenesis,
including disruption of signaling inducing vasculogenic mimicry (e.g.
tumor stem cell activity); [0005] reducing, blocking, or reversing the
mechanisms of chemo-resistance to chemotherapeutic drugs, in order to
enhance effectiveness of chemotherapy, preferably while increasing
anti-tumor, pro-apoptotic activity; [0006] supporting a metabolic shift
from aerobic glycolysis (the "Warburg Effect") to glucose oxidation,
which promotes or renews a capacity for undergoing apoptosis; [0007]
blocking, interrupting, or attenuating intracellular tumor cell signal
transduction pathways that promote tumor cell growth; [0008] inhibiting
intercellular signaling pathways that facilitate tumor invasion into
local tissues and tumor metastasis (i.e., the spread of tumor cells to
other tissues or organs); [0009] Inducing opioid immune modulation that
has an inhibitory effect on cell proliferation. (Donahue R N et al.,
Low-dose naltrexone targets opioid growth factor receptor pathway to
inhibit cell proliferation: mechanistic evidence from tissue culture
model, Exp. Biol. Med. (Maywood), 2011 Sep. 1; 236(9); 1036-50) [0010]
reducing or avoiding toxic side effects of chemotherapy and any other
active ingredients added to a treatment regimen; and [0011] augmenting or
enhancing the patient's host defenses (particularly the host immune
system), their general health and well-being.
[0012] In some embodiments, the present invention provides a unique
approach for the treatment of cancer, combining use of one or more agents
conventionally included in cancer treatments with administration of one
or more naturally-occurring compounds and/or nutrients, e.g.,
"nutraceuticals".
[0013] In some embodiments, treatment protocols described herein are
designed to inhibit, arrest, and/or otherwise disrupt, or, where
appropriate, enhance endogenous signaling pathways and/or upregulate
anti-angiogenic regulators (such as angiostatin, endostatin, or
thrombospodin-1) that, when dysregulated, lead to the formation or
support the development of cancerous growth or tumors.
[0014] In a preferred embodiment, the present invention is directed to
compositions and methods for the treatment of cancers or tumors that are
epithelial cell related.
[0015] In another embodiment, the present invention is designed to prevent
the recurrence of cancer, by continuing the disclosed treatment regimen
once it has been determined that the cancer or tumor is in remission or,
in other words, there is no evidence of disease.
[0016] One unique feature of the method and compositions described herein
is that the combination of compounds and dosages of each can be tailored
for each individual or patient in order to maximize the benefit realized
for that particular patient. In this respect, the treatment regimen will
be based on a pretreatment analysis of specific parameters, for example,
on an analysis of blood or biopsied tissue obtained from the patient to
be treated, prior to initiating the regimen.
[0017] The present invention provides a unique integrative approach to
cancer therapy, in which conventional oncology can be merged with
complementary modalities. The complementary aspect emphasizes the use of
natural compounds and non-chemotherapeutic drugs to facilitate a
synergistic approach in which each element of treatment, both
conventional and non-conventional, is designed to inhibit angiogenesis
and the oncogenic signaling transduction pathways within cancer cells and
the intercellular signaling between tumor cells and their local cellular
and biochemical micro-environment, with a strong emphasis on disruption
of the intercellular signaling that fuels the ongoing processes of tumor
angiogenesis.
[0018] The present invention encompasses a variety of novel insights,
including defining the sources of various problems associated with
certain conventional chemotherapeutic regimens, as described herein.
[0019] For example, in some embodiments, the present invention provides
therapeutic modalities that target multiple pathways. In some
embodiments, the present invention provides therapeutic regimens
utilizing a combination of components that together target a particular
pathway multiple times and/or in multiple ways (see, for example, as
illustrated in FIG. 1).
[0020] In some embodiments, the present invention encompasses the
recognition that a variety of agents that are not traditional
chemotherapeutic agents in that, for example, they do not specifically
modulate a particular single druggable target (e.g., inhibit an oncogene
product or enhance a tumor suppressor gene product), are useful in
treating cancer, particularly when utilized in combination as described
herein.
[0021] In some embodiments, the present invention encompasses the
recognition that certain agents developed and/or utilized for treatment
of non-life-threatening and/or chronic diseases, disorders and conditions
are unexpectedly particularly useful in the treatment of cancer when they
target pathways as described herein and/or are utilized in combination as
described herein.
[0022] In some embodiments, the present invention encompasses the
recognition that chronic administration of agents, particularly of agents
with high therapeutic indeces, and/or particularly at doses well below
their maximum tolerated doses is unexpectedly particularly useful in the
treatment of cancer, particularly when utilized in combination as
described herein.
[0023] Various other insights and advantages provided by the present
disclosure are discussed in further detail herein.
[0024] In certain particularly preferred embodiments of the present
invention, methods and/or compositions are individually tailored to the
patient in need of treatment and are based on a number of parameters
measured in, for example, blood samples or tissue biopsies taken from the
patient to be treated, to determine the optimal combination and dosages
of each compound of the composition selected for the treatment of that
individual.
[0025] It is also contemplated in certain embodiments that, once a cancer
is in remission (e.g., by following the methods and teachings disclosed
herein), the patient can continue on a treatment regimen according to the
invention, in order to maintain or lengthen the period of remission, or
until one or more abnormally upregulated cancer-supportive metabolic
and/or signaling pathways or one or more abnormally downregulated
cancer-suppressive metabolic and/or signaling pathways return to normal.
In this way, following the methods of the invention helps to prevent
recurrence of the disease.
[0026] In some embodiments, treatment regimens provided by the present
invention comprise administration of a combination of active ingredients,
which may be administered in addition to conventional anticancer
therapeutics (chemotherapeutic agents), so that an inventive combination
will often include naturally occurring compounds, nutrients, extracts or
other nutraceutical compounds such as, for instance, Curcumin, etc.,
non-chemotherapeutic agents, such as, for instance, Metformin,
Naltrexone, Melatonin, etc.; and/or chemotherapeutic agents such as
cyclophosphamide. In some embodiments, a composition to be administered
to a cancer patient may comprise a combination of from 3 to 8 or more of
these nutraceutical compounds (as currently available or as approved
drugs), non-chemotherapeutic drugs, and chemotherapeutic drugs (see, for
example, FIG. 1). A particular combination of compounds and dosage of
each may be determined by one skilled in the art, for example, the
patient's oncologist or primary care physician.
[0027] Therefore, the present invention is directed in general to a unique
integrative approach to cancer therapy, in which conventional oncology
may be merged with complementary modalities. The complementary aspect
emphasizes the use of low toxicity combinations to augment and/or improve
use of conventional agents to promote synergistic effects or compound
effects. In particular, components of inventive combination therapy
treatments are designed to collectively abrogate angiogenesis and the
oncogenic signaling transduction pathways within cancer cells and the
intercellular signaling between tumor cells and their local cellular and
biochemical micro-environment, to the end that all or as many biological
systems as possible that contribute to the survival of the cancer will be
addressed, to the detriment of the cancer and to the improvement of
health of the patient. Active ingredients included in the novel approach
to cancer treatment described herein have been demonstrated to improve
the conventional treatment of cancers, e.g., cancers of epithelial origin
(such as breast cancer, esophageal cancer, uterine cancer, liver cancer,
etc.), and all forms of cancer or other diseases where regulation of
angiogenesis and multiple signaling pathways is called for.
[0028] In various aspects, therefore, the present invention provides
compositions for administration to a patient diagnosed with cancer,
optionally as an adjunct to a chemotherapy, a composition comprising at
least three ingredients, each of which is capable of regulating a
specific metabolic pathway or intracellular signaling pathway or
intercellular signaling pathway implicated in the advent of the cancer,
wherein at least three such pathways are addressed. The compositions of
the invention may be in the form of an admixture of three or more
ingredients, or they may simply be separate ingredients packaged to be
used together, so that specific endogenous pathways or processes in the
cancer patient are treated simultaneously.
[0029] In one embodiment, a composition according to the invention
comprises at least three different compounds, wherein at least one

DESCRIPTION OF THE DRAWING
[0047] FIG. 1 presents an illustration of an inventive strategy of
treating cancer by targeting multiple pathways.
DEFINITIONS
[0048] Below are provided certain definitions of terms used herein, many
or most of which confirm common understandings of those skilled in the
art.
[0049] Activating agent: As used herein, the term "activating agent"
refers to an agent whose presence or level correlates with elevated level
or activity of a target, as compared with that observed absent the agent
(or with the agent at a different level). In some embodiments, an
activating agent is one whose presence or level correlates with a target
level or activity that is comparable to or greater than a particular
reference level or activity (e.g., that observed under appropriate
reference conditions, such as presence of a known activating agent, e.g.,
a positive control).
[0050] Administration: As used herein, the term "administration" refers to
the administration of a composition to a subject or system.
Administration to an animal subject (e.g., to a human) may be by any
appropriate route. For example, in some embodiments, administration may
be bronchial (including by bronchial instillation), buccal, enteral,
interdermal, intra-arterial, intradermal, intragastric, intramedullary,
intramuscular, intranasal, intraperitoneal, intrathecal, intravenous,
intraventricular, mucosal, nasal, oral, rectal, subcutaneous, sublingual,
topical, tracheal (including by intratracheal instillation), transdermal,
vaginal and vitreal.
[0051] Adressed: By "addressed", when used in reference to a process or
pathway targeted by therapy as described herein is meant that the process
or pathway will be altered by the administration of an inventive
therapeutic protocol (e.g., by one or a combination of agents included in
an inventive therapeutic protocol) toward normalcy, that is, toward the
characteristic function of that process or pathway in a normal
individual, or an individual that does not suffer from the cancer being
treated.
[0052] Adult: As used herein, the term "adult" refers to a human eighteen
years of age or older. Body weights among adults can vary widely with a
typical range being 90 pounds to 250 pounds.
[0053] Agent: As will be clear to those skilled in the art, the term
"agent" as used herein may refer to a compound or entity of any chemical
class including, for example, polypeptides, nucleic acids, saccharides,
lipids, small molecules, metals, or combinations thereof. In some
embodiments, an agent is or comprises a natural product in that it is
found in and/or is obtained from nature. In some embodiments, an agent is
or comprises one or more entities that is man-made in that it is
designed, engineered, and/or produced through action of the hand of man
and/or is not found in nature. In some embodiments, an agent may be
utilized in isolated or pure form; in some embodiments, an agent may be
utilized in crude form. In some embodiments, potential agents are
provided as collections or libraries, for example that may be screened to
identify or characterize active agents within them. Some particular
embodiments of agents that may be utilized in accordance with the present
invention include small molecules, antibodies, antibody fragments,
aptamers, nucleic acids (e.g., siRNAs, shRNAs, DNA/RNA hybrids, antisense
oligonucleotides, ribozymes), peptides, peptide mimetics, etc. In some
embodiments, an agent is or comprises a polymer. In some embodiments, an
agent is not a polymer and/or is substantially free of any polymer. In
some embodiments, an agent contains at least one polymeric moiety. In
some embodiments, an agent lacks or is substantially free of any
polymeric moiety.
[0054] Antagonist: As used herein, the term "antagonist" refers to an
agent that i) inhibits, decreases or reduces the effects of another
agent; and/or ii) inhibits, decreases, reduces, or delays one or more
biological events. Antagonists may be or include agents of any chemical
class including, for example, small molecules, polypeptides, nucleic
acids, carbohydrates, lipids, metals, and/or any other entity that shows
the relevant inhibitory activity. An antagonist may be direct (in which
case it exerts its influence directly upon its target) or indirect (in
which case it exerts its influence by other than binding to its target;
e.g., by interacting with a regulator of the target, for example so that
level or activity of the target is altered).
[0055] Antibody: As is known in the art, an "antibody" is an
immunoglobulin that binds specifically to a particular antigen. The term
encompasses immunoglobulins that are naturally produced in that they are
generated by an organism reacting to the antigen, and also those that are
synthetically produced or engineered. An antibody may be monoclonal or
polyclonal. An antibody may be a member of any immunoglobulin class,
including any of the human classes: IgG, IgM, IgA, and IgD. A typical
immunoglobulin (antibody) structural unit as understood in the art, is
known to comprise a tetramer. Each tetramer is composed of two identical
pairs of polypeptide chains, each pair having one "light" (approximately
25 kD) and one "heavy" chain (approximately 50-70 kD). The N-terminus of
each chain defines a variable region of about 100 to 110 or more amino
acids primarily responsible for antigen recognition. The terms "variable
light chain" (VL) and "variable heavy chain" (VH) refer to these light
and heavy chains respectively. Each variable region is further subdivided
into hypervariable (HV) and framework (FR) regions. The hypervariable
regions comprise three areas of hypervariability sequence called
complementarity determining regions (CDR 1, CDR 2 and CDR 3), separated
by four framework regions (FR1, FR2, FR2, and FR4) which form a
beta-sheet structure and serve as a scaffold to hold the HV regions in
position. The C-terminus of each heavy and light chain defines a constant
region consisting of one domain for the light chain (CL) and three for
the heavy chain (CH1, CH2 and CH3). In some embodiments, the term "full
length" is used in reference to an antibody to mean that it contains two
heavy chains and two light chains, optionally associated by disulfide
bonds as occurs with naturally-produced antibodies. In some embodiments,
an antibody is produced by a cell. In some embodiments, an antibody is
produced by chemical synthesis. In some embodiments, an antibody is
derived from a mammal. In some embodiments, an antibody is derived from
an animal such as, but not limited to, mouse, rat, horse, pig, or goat.
In some embodiments, an antibody is produced using a recombinant cell
culture system. In some embodiments, an antibody may be a purified
antibody (for example, by immune-affinity chromatography). In some
embodiments, an antibody may be a human antibody. In some embodiments, an
antibody may be a humanized antibody (antibody from non-human species
whose protein sequences have been modified to increase their similarity
to antibody variants produced naturally in humans). In some embodiments,
an antibody may be a chimeric antibody (antibody made by combining
genetic material from a non-human source, e.g., mouse, rat, horse, or
pig, with genetic material from humans).
[0056] Antibody agent: As used herein, the term "antibody agent" refers to
an agent that specifically binds to a particular antigen. In some
embodiments, the term encompasses any polypeptide with immunoglobulin
structural elements sufficient to confer specific binding. Suitable
antibody agents include, but are not limited to, human antibodies,
primatized antibodies, chimeric antibodies, bi-specific antibodies,
humanized antibodies, conjugated antibodies (i.e., antibodies conjugated
or fused to other proteins, radiolabels, cytotoxins), Small Modular
ImmunoPharmaceuticals ("SMIPs.TM."), single chain antibodies, cameloid
antibodies, and antibody fragments. As used herein, the term "antibody
agent" also includes intact monoclonal antibodies, polyclonal antibodies,
single domain antibodies (e.g., shark single domain antibodies (e.g.,
IgNAR or fragments thereof)), multispecific antibodies (e.g. bi-specific
antibodies) formed from at least two intact antibodies, and antibody
fragments so long as they exhibit the desired biological activity. In
some embodiments, the term encompasses stapled peptides. In some
embodiments, the term encompasses one or more antibody-like binding
peptidomimetics. In some embodiments, the term encompasses one or more
antibody-like binding scaffold proteins. In come embodiments, the term
encompasses monobodies or adnectins. In many embodiments, an antibody
agent is or comprises a polypeptide whose amino acid sequence includes
one or more structural elements recognized by those skilled in the art as
a complementarity determining region (CDR); in some embodiments an
antibody agent is or comprises a polypeptide whose amino acid sequence
includes at least one CDR (e.g., at least one heavy chain CDR and/or at
least one light chain CDR) that is substantially identical to one found
in a reference antibody. In some embodiments an included CDR is
substantially identical to a reference CDR in that it is either identical
in sequence or contains between 1-5 amino acid substitutions as compared
with the reference CDR. In some embodiments an included CDR is
substantially identical to a reference CDR in that it shows at least 85%,
86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or
100% sequence identity with the reference CDR. In some embodiments an
included CDR is substantially identical to a reference CDR in that it
shows at least 96%, 96%, 97%, 98%, 99%, or 100% sequence identity with
the reference CDR. In some embodiments an included CDR is substantially
identical to a reference CDR in that at least one amino acid within the
included CDR is deleted, added, or substituted as compared with the
reference CDR but the included CDR has an amino acid sequence that is
otherwise identical with that of the reference CDR. In some embodiments
an included CDR is substantially identical to a reference CDR in that 1-5
amino acids within the included CDR are deleted, added, or substituted as
compared with the reference CDR but the included CDR has an amino acid
sequence that is otherwise identical to the reference CDR. In some
embodiments an included CDR is substantially identical to a reference CDR
in that at least one amino acid within the included CDR is substituted as
compared with the reference CDR but the included CDR has an amino acid
sequence that is otherwise identical with that of the reference CDR. In
some embodiments an included CDR is substantially identical to a
reference CDR in that 1-5 amino acids within the included CDR are
deleted, added, or substituted as compared with the reference CDR but the
included CDR has an amino acid sequence that is otherwise identical to
the reference CDR. In some embodiments, an antibody agent is or comprises
a polypeptide whose amino acid sequence includes structural elements
recognized by those skilled in the art as an immunoglobulin variable
domain. In some embodiments, an antibody agent is a polypeptide protein
having a binding domain which is homologous or largely homologous to an
immunoglobulin-binding domain.
[0057] Approximately: As used herein, the terms "approximately" and
"about" are each intended to encompass normal statistical variation as
would be understood by those of ordinary skill in the art as appropriate
to the relevant context. In certain embodiments, the terms
"approximately" or "about" each refer to a range of values that fall
within 25%, 20%, 19%, 18%, 17%, 16%, 15%, 14%, 13%, 12%, 11%, 10%, 9%,
8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or less in either direction (greater than
or less than) of a stated value, unless otherwise stated or otherwise
evident from the context (e.g., where such number would exceed 100% of a
possible value).
[0058] Associated with: Two events or entities are "associated" with one
another, as that term is used herein, if the presence, level and/or form
of one is correlated with that of the other. For example, a particular
entity (e.g., polypeptide) is considered to be associated with a
particular disease, disorder, or condition, if its presence, level and/or
form correlates with incidence of and/or susceptibility of the disease,
disorder, or condition (e.g., across a relevant population). In some
embodiments, two or more entities are physically "associated" with one
another if they interact, directly or indirectly, so that they are and
remain in physical proximity with one another. In some embodiments, two
or more entities that are physically associated with one another are
covalently linked to one another; in some embodiments, two or more
entities that are physically associated with one another are not
covalently linked to one another but are non-covalently associated, for
example by means of hydrogen bonds, van der Waals interaction,
hydrophobic interactions, magnetism, and combinations thereof.
[0059] Combination therapy: As used herein, the term "combination therapy"
refers to those situations in which a subject is simultaneously exposed
to two or more therapeutic regimens (e.g., two or more therapeutic
agents). In some embodiments, two or more agents may be administered
simultaneously; in some embodiments, such agents may be administered
sequentially; in some embodiments, such agents are administered in
overlapping dosing regimens.
[0060] Comparable: The term "comparable", as used herein, refers to two or
more agents, entities, situations, sets of conditions, etc that may not
be identical to one another but that are sufficiently similar to permit
comparison therebetween so that conclusions may reasonably be drawn based
on differences or similarities observed. In some embodiments, comparable
sets of conditions, circumstances, individuals, or populations are
characterized by a plurality of substantially identical features and one
or a small number of varied features. Those of ordinary skill in the art
will understand, in context, what degree of identity is required in any
given circumstance for two or more such agents, entities, situations,
sets of conditions, etc to be considered comparable. For example, those
of ordinary skill in the art will appreciate that sets of circumstances,
individuals, or populations are comparable to one another when
characterized by a sufficient number and type of substantially identical
features to warrant a reasonable conclusion that differences in results
obtained or phenomena observed under or with different sets of
circumstances, individuals, or populations are caused by or indicative of
the variation in those features that are varied.
[0061] Composition: A "composition" or a "pharmaceutical composition"
according to this invention, refers to the combination of two or more
agents as described herein for co-administration or administration as
part of the same regimen. It is not required in all embodiments that the
combination of agents result in physical admixture, that is,
administration as separate co-agents each of the components of the
composition is possible; however many patients or practitioners in the
field may find it advantageous to prepare a composition that is an
admixture of two or more of the ingredients in a pharmaceutically
acceptable carrier, diluent, or excipient, making it possible to
administer the component ingredients of the combination at the same time.
[0062] Comprising: A composition or method described herein as
"comprising" one or more named elements or steps is open-ended, meaning
that the named elements or steps are essential, but other elements or
steps may be added within the scope of the composition or method. To
avoid prolixity, it is also understood that any composition or method
described as "comprising" (or which "comprises") one or more named
elements or steps also describes the corresponding, more limited
composition or method "consisting essentially of" (or which "consists
essentially of") the same named elements or steps, meaning that the
composition or method includes the named essential elements or steps and
may also include additional elements or steps that do not materially
affect the basic and novel characteristic(s) of the composition or
method. It is also understood that any composition or method described
herein as "comprising" or "consisting essentially of" one or more named
elements or steps also describes the corresponding, more limited, and
closed-ended composition or method "consisting of" (or "consists of") the
named elements or steps to the exclusion of any other unnamed element or
step. In any composition or method disclosed herein, known or disclosed
equivalents of any named essential element or step may be substituted for
that element or step.
[0063] Determine: Many methodologies described herein include a step of
"determining". Those of ordinary skill in the art, reading the present
specification, will appreciate that such "determining" can utilize or be
accomplished through use of any of a variety of techniques available to
those skilled in the art, including for example specific techniques
explicitly referred to herein. In some embodiments, determining involves
manipulation of a physical sample. In some embodiments, determining
involves consideration and/or manipulation of data or information, for
example utilizing a computer or other processing unit adapted to perform
a relevant analysis. In some embodiments, determining involves receiving
relevant information and/or materials from a source. In some embodiments,
determining involves comparing one or more features of a sample or entity
to a comparable reference.
[0064] Dosage form: As used herein, the term "dosage form" refers to a
physically discrete unit of an active agent (e.g., a therapeutic or
diagnostic agent) for administration to a subject. Each unit contains a
predetermined quantity of active agent. In some embodiments, such
quantity is a unit dosage amount (or a whole fraction thereof)
appropriate for administration in accordance with a dosing regimen that
has been determined to correlate with a desired or beneficial outcome
when administered to a relevant population (i.e., with a therapeutic
dosing regimen). Those of ordinary skill in the art appreciate that the
total amount of a therapeutic composition or agent administered to a
particular subject is determined by one or more attending physicians and
may involve administration of multiple dosage forms.
[0065] Dosing regimen: As used herein, the term "dosing regimen" refers to
a set of unit doses (typically more than one) that are administered
individually to a subject, typically separated by periods of time. In
some embodiments, a given therapeutic agent has a recommended dosing
regimen, which may involve one or more doses. In some embodiments, a
dosing regimen comprises a plurality of doses each of which are separated
from one another by a time period of the same length; in some
embodiments, a dosing regimen comprises a plurality of doses and at least
two different time periods separating individual doses. In some
embodiments, all doses within a dosing regimen are of the same unit dose
amount. In some embodiments, different doses within a dosing regimen are
of different amounts. In some embodiments, a dosing regimen comprises a
first dose in a first dose amount, followed by one or more additional
doses in a second dose amount different from the first dose amount. In
some embodiments, a dosing regimen comprises a first dose in a first dose
amount, followed by one or more additional doses in a second dose amount
same as the first dose amount In some embodiments, a dosing regimen is
correlated with a desired or beneficial outcome when administered across
a relevant population (i.e., is a therapeutic dosing regimen).
[0066] Metronomic therapy: As used herein, the term "metronomic therapy"
or "metronomic chemotherapy" refers to the frequent, e.g., daily,
adminitration of therapeutic agents at doses significantly less than the
maximum tolerated dose (MTD). For example, metronomic administration of
Cyclophosphamide at a low dose, e.g., 50 mg/day as compared with
representative MTD doses of 600 mg/m.sup.2-750 mg/m.sup.2 for three
weeks, has shown promising results in a wide range of cancers. N. Penel
et al., Critical Reviews in Oncology/Hematology, 82:40-50 (2012).
[0067] Modulator: The term "modulator" is used to refer to an entity whose
presence or level in a system in which an activity of interest is
observed correlates with a change in level and/or nature of that activity
as compared with that observed under otherwise comparable conditions when
the modulator is absent. In some embodiments, a modulator is an
activator, in that activity is increased in its presence as compared with
that observed under otherwise comparable conditions when the modulator is
absent. In some embodiments, a modulator is an antagonist or inhibitor,
in that activity is reduced in its presence as compared with otherwise
comparable conditions when the modulator is absent. In some embodiments,
a modulator interacts directly with a target entity whose activity is of
interest. In some embodiments, a modulator interacts indirectly (i.e.,
directly with an intermediate agent that interacts with the target
entity) with a target entity whose activity is of interest. In some
embodiments, a modulator affects level of a target entity of interest;
alternatively or additionally, in some embodiments, a modulator affects
activity of a target entity of interest without affecting level of the
target entity. In some embodiments, a modulator affects both level and
activity of a target entity of interest, so that an observed difference
in activity is not entirely explained by or commensurate with an observed
difference in level.
[0068] Patient: As used herein, the term "patient" or "subject" refers to
any organism to which a provided composition is or may be administered,
e.g., for experimental, diagnostic, prophylactic, cosmetic, and/or
therapeutic purposes. Typical patients include animals (e.g., mammals
such as mice, rats, rabbits, non-human primates, and/or humans). In some
embodiments, a patient is a human. In some embodiments, a patient is
suffering from or susceptible to one or more disorders or conditions. In
some embodiments, a patient displays one or more symptoms of a disorder
or condition. In some embodiments, a patient has been diagnosed with one
or more disorders or conditions. In some embodiments, the disorder or
condition is or includes cancer, or presence of one or more tumors. In
some embodiments, such cancer or tumor is or comprises a cancer of the
prostate, or tumor in the prostate. In some embodiments, the disorder or
condition is metastatic cancer.
[0069] Pharmaceutically acceptable: As used herein, the term
"pharmaceutically acceptable" applied to the carrier, diluent, or
excipient used to formulate a composition as disclosed herein means that
the carrier, diluent, or excipient must be compatible with the other
ingredients of the composition and not deleterious to the recipient
thereof.
[0070] Pharmaceutically acceptable salt: As used herein, the term
"pharmaceutically acceptable salt" means a salt prepared by conventional
means, and are well known by those skilled in the art. Suitable
pharmaceutically acceptable salts include, but are not limited to, salts
of pharmaceutically acceptable inorganic acids included but not limited
to hydrochloric, sulphuric, phosphoric, nitric, carbonic, boric,
sulfamic, and hydrobromic acids, or salts of pharmaceutically acceptable
organic acids such as acetic, propionic, butyric, tartaric, maleic,
hydroxymaleic, fumaric, malic, citric, lactic, mucic, gluconic, benzoic,
succinic, oxalic, phenylacetic, methanesulphonic, toluenesulphonic,
benzenesulphonic, salicylic, sulphanilic, aspartic, glutamic, edetic,
stearic, palmitic, oleic, lauric, pantothenic, tannic, ascorbic,
ammonium, tetaalkylammonium, and valeric acids and the like. General
information on types of pharmaceutically acceptable salts and their
formation is known to those skilled in the art and is as described in
general texts such as "Handbook of Pharmaceutical Salts" P. H. Stahl, C.
G. Wermuth, 1st edition, 2002, Wiley-VCH.
[0071] Pharmaceutical composition: As used herein, the term
"pharmaceutical composition" refers to an active agent, formulated
together with one or more pharmaceutically acceptable carriers. In some
embodiments, active agent is present in unit dose amount appropriate for
administration in a therapeutic regimen that shows a statistically
significant probability of achieving a predetermined therapeutic effect
when administered to a relevant population. In some embodiments,
pharmaceutical compositions may be specially formulated for
administration in solid or liquid form, including those adapted for the
following: oral administration, for example, drenches (aqueous or
non-aqueous solutions or suspensions), tablets, e.g., those targeted for
buccal, sublingual, and systemic absorption, boluses, powders, granules,
pastes for application to the tongue; parenteral administration, for
example, by subcutaneous, intramuscular, intravenous or epidural
injection as, for example, a sterile solution or suspension, or
sustained-release formulation; topical application, for example, as a
cream, ointment, or a controlled-release patch or spray applied to the
skin, lungs, or oral cavity; intravaginally or intrarectally, for
example, as a pessary, cream, or foam; sublingually; ocularly;
transdermally; or nasally, pulmonary, and to other mucosal surfaces.
[0072] Reference: The term "reference" is often used herein to describe a
standard or control agent or value against which an agent or value of
interest is compared. In some embodiments, a reference agent is tested
and/or a reference value is determined substantially simultaneously with
the testing or determination of the agent or value of interest. In some
embodiments, a reference agent or value is a historical reference,
optionally embodied in a tangible medium. Typically, as would be
understood by those skilled in the art, a reference agent or value is
determined or characterized under conditions comparable to those utilized
to determine or characterize the agent or value of interest.
[0073] Refractory: The term "refractory" as used herein, refers to any
subject or condition that does not respond with an expected clinical
efficacy following the administration of provided compositions as
normally observed by practicing medical personnel.
[0074] Response: As used herein, a response to treatment may refer to any
beneficial alteration in a subject's condition that occurs as a result of
or correlates with treatment. Such alteration may include stabilization
of the condition (e.g., prevention of deterioration that would have taken
place in the absence of the treatment), amelioration of symptoms of the
condition, and/or improvement in the prospects for cure of the condition,
etc. It may refer to a subject's response or to a tumor's response. Tumor
or subject response may be measured according to a wide variety of
criteria, including clinical criteria and objective criteria. Techniques
for assessing response include, but are not limited to, clinical
examination, positron emission tomatography, chest X-ray CT scan, MRI,
ultrasound, endoscopy, laparoscopy, presence or level of tumor markers in
a sample obtained from a subject, cytology, and/or histology. Many of
these techniques attempt to determine the size of a tumor or otherwise
determine the total tumor burden. Methods and guidelines for assessing
response to treatment are discussed in Therasse et. al., "New guidelines
to evaluate the response to treatment in solid tumors", European
Organization for Research and Treatment of Cancer, National Cancer
Institute of the United States, National Cancer Institute of Canada, J.
Natl. Cancer Inst., 2000, 92(3):205-216. The exact response criteria can
be selected in any appropriate manner, provided that when comparing
groups of tumors and/or patients, the groups to be compared are assessed
based on the same or comparable criteria for determining response rate.
One of ordinary skill in the art will be able to select appropriate
criteria.
[0075] Small molecule: As used herein, the term "small molecule" means a
low molecular weight organic and/or inorganic compound. In general, a
"small molecule" is a molecule that is less than about 5 kilodaltons (kD)
in size. In some embodiments, a small molecule is less than about 4 kD, 3
kD, about 2 kD, or about 1 kD. In some embodiments, the small molecule is
less than about 800 daltons (D), about 600 D, about 500 D, about 400 D,
about 300 D, about 200 D, or about 100 D. In some embodiments, a small
molecule is less than about 2000 g/mol, less than about 1500 g/mol, less
than about 1000 g/mol, less than about 800 g/mol, or less than about 500
g/mol. In some embodiments, a small molecule is not a polymer. In some
embodiments, a small molecule does not include a polymeric moiety. In
some embodiments, a small molecule is not a protein or polypeptide (e.g.,
is not an oligopeptide or peptide). In some embodiments, a small molecule
is not a polynucleotide (e.g., is not an oligonucleotide). In some
embodiments, a small molecule is not a polysaccharide. In some
embodiments, a small molecule does not comprise a polysaccharide (e.g.,
is not a glycoprotein, proteoglycan, glycolipid, etc.). In some
embodiments, a small molecule is not a lipid. In some embodiments, a
small molecule is a modulating agent. In some embodiments, a small
molecule is biologically active. In some embodiments, a small molecule is
detectable (e.g., comprises at least one detectable moiety). In some
embodiments, a small molecule is a therapeutic.
[0076] Solid form: As is known in the art, many chemical entities (in
particular many organic molecules and/or many small molecules) can adopt
a variety of different solid forms such as, for example, amorphous forms
and/or crystalline forms (e.g., polymorphs, hydrates, solvates, etc). In
some embodiments, such entities may be utilized in any form, including in
any solid form. In some embodiments, such entities are utilized in a
particular form, for example in a particular solid form.
[0077] Stage of cancer: As used herein, the term "stage of cancer" refers
to a qualitative or quantitative assessment of the level of advancement
of a cancer. Criteria used to determine the stage of a cancer include,
but are not limited to, the size of the tumor and the extent of
metastases (e.g., localized or distant).
[0078] Substantially: As used herein, the term "substantially" refers to
the qualitative condition of exhibiting total or near-total extent or
degree of a characteristic or property of interest. One of ordinary skill
in the biological arts will understand that biological and chemical
phenomena rarely, if ever, go to completion and/or proceed to
completeness or achieve or avoid an absolute result. The term
"substantially" is therefore used herein to capture the potential lack of
completeness inherent in many biological and chemical phenomena.
[0079] Susceptible to: An individual who is "susceptible to" a disease,
disorder, or condition (e.g., influenza) is at risk for developing the
disease, disorder, or condition. In some embodiments, an individual who
is susceptible to a disease, disorder, or condition does not display any
symptoms of the disease, disorder, or condition. In some embodiments, an
individual who is susceptible to a disease, disorder, or condition has
not been diagnosed with the disease, disorder, and/or condition. In some
embodiments, an individual who is susceptible to a disease, disorder, or
condition is an individual who has been exposed to conditions associated
with development of the disease, disorder, or condition. In some
embodiments, a risk of developing a disease, disorder, and/or condition
is a population-based risk (e.g., family members of individuals suffering
from the disease, disorder, or condition).
[0080] Symptoms are reduced: According to the present invention, "symptoms
are reduced" when one or more symptoms of a particular disease, disorder
or condition is reduced in magnitude (e.g., intensity, severity, etc.)
and/or frequency. For purposes of clarity, a delay in the onset of a
particular symptom is considered one form of reducing the frequency of
that symptom. Many cancer patients with smaller tumors have no symptoms.
It is not intended that the present invention be limited only to cases
where the symptoms are eliminated. The present invention specifically
contemplates treatment such that one or more symptoms is/are reduced (and
the condition of the subject is thereby "improved"), albeit not
completely eliminated.
[0081] Therapeutic agent: As used herein, the phrase "therapeutic agent"
refers to any agent that elicits a desired pharmacological effect when
administered to an organism. In some embodiments, an agent is considered
to be a therapeutic agent if it demonstrates a statistically significant
effect across an appropriate population. In some embodiments, the
appropriate population may be a population of model organisms. In some
embodiments, an appropriate population may be defined by various
criteria, such as a certain age group, gender, genetic background,
preexisting clinical conditions, etc. In some embodiments, a therapeutic
agent is any substance that can be used to alleviate, ameliorate,
relieve, inhibit, prevent, delay onset of, reduce severity of, and/or
reduce incidence of one or more symptoms or features of a disease,
disorder, and/or condition.
[0082] Therapeutically effective amount: The term "therapeutically
effective amount", as used herein and applied to any individual agent for
use according to the invention means an amount which, when administered
to the individual in need in the context of inventive therapy, will
block, attenuate, or reverse a cancer-supportive process occurring in
said individual, or will enhance or increase a cancer-suppressive process
in said individual. In the context of cancer treatment, a
"therapeutically effective amount" is an amount which, when administered
to an individual diagnosed with a cancer, will prevent, inhibit, or
reduce the further development of cancer in the individual. A
particularly preferred "therapeutically effective amount" of a
composition described herein reverses (in a therapeutic treatment) the
development of a malignancy such as a pancreatic carcinoma or helps
achieve or prolong remission of a malignancy. A therapeutically effective
amount administered to an individual to treat a cancer in that individual
may be the same or different from a therapeutically effective amount
administered to promote remission or inhibit metastasis. As with most
cancer therapies, the therapeutic methods described herein are not to be
interpreted as, restricted to, or otherwise limited to a "cure" for
cancer; rather the methods of treatment are directed to the use of the
described compositions to "treat" a cancer, i.e., to effect a desirable
or beneficial change in the health of an individual who has cancer. Such
benefits are recognized by skilled healthcare providers in the field of
oncology and include, but are not limited to, a decrease in tumor size
(tumor regression), an improvement in vital functions (e.g., improved
function of cancerous tissues or organs), a decrease or inhibition of
further metastasis, a decrease in opportunistic infections, an increased
survivability, a decrease in pain, improved motor function, improved
cognitive function, improved feeling of energy (vitality, decreased
malaise), improved feeling of well-being, restoration of normal appetite,
restoration of healthy weight gain, and combinations thereof. In
addition, regression of a particular tumor in an individual (e.g., as the
result of treatments described herein) may also be assessed by taking
samples of cancer cells from the site of a tumor such as a pancreatic
adenocarcinoma (e.g., over the course of treatment) and testing the
cancer cells for the level of metabolic and signaling markers to monitor
the status of the cancer cells to verify at the molecular level the
regression of the cancer cells to a less malignant phenotype. For
example, tumor regression induced by employing the methods of this
invention would be indicated by finding a decrease in any of the
pro-angiogenic markers discussed above, an increase in anti-angiogenic
markers described herein, the normalization (i.e., alteration toward a
state found in normal individuals not suffering from cancer) of metabolic
pathways, intercellular signaling pathways, or intracellular signaling
pathways that exhibit abnormal activity in individuals diagnosed with
cancer. The term "treating" also may include the reduction,
stabilization, regression, elimination of cancer, more particularly for
the reduction, stabilization, regression, elimination of epithelial cell
related cancers related to abnormal growth of epithelial cells. The term
"treating" may also include the promotion of cellular health in one or
more organs or systems of the individual prescribed a treatment regimen
as described herein.
[0083] Therapeutic index: As is known in the art, the term "therapeutic
index" refers to a ratio of unacceptably unsafe dose to efficacious dose
for a particular index. Specifically, the therapeutix index is the ratio
of TD.sub.50 (Dose that causes a toxic response in 50% of the relevant
population) and ED.sub.50 (dose that is therapeutically effective in 50%
of the population).
[0084] Therapeutic regimen: A "therapeutic regimen", as that term is used
herein, refers to a dosing regimen whose administration across a relevant
population is correlated with a desired or beneficial therapeutic
outcome.
[0085] Treatment: As used herein, the term "treatment" (also "treat" or
"treating") refers to any administration of a substance (e.g.,
anti-receptor tyrosine kinases antibodies or receptor tyrosine kinase
antagonists) that partially or completely alleviates, ameliorates,
relives, inhibits, delays onset of, reduces severity of, and/or reduces
incidence of one or more symptoms, features, and/or causes of a
particular disease, disorder, and/or condition (e.g., cancer). Such
treatment may be of a subject who does not exhibit signs of the relevant
disease, disorder and/or condition and/or of a subject who exhibits only
early signs of the disease, disorder, and/or condition. Alternatively or
additionally, such treatment may be of a subject who exhibits one or more
established signs of the relevant disease, disorder and/or condition. In
some embodiments, treatment may be of a subject who has been diagnosed as
suffering from the relevant disease, disorder, and/or condition. In some
embodiments, treatment may be of a subject known to have one or more
susceptibility factors that are statistically correlated with increased
risk of development of the relevant disease, disorder, and/or condition.
[0086] Unit dose: The expression "unit dose" as used herein refers to an
amount administered as a single dose and/or in a physically discrete unit
of a pharmaceutical composition. In many embodiments, a unit dose
contains a predetermined quantity of an active agent. In some
embodiments, a unit dose contains an entire single dose of the agent. In
some embodiments, more than one unit dose is administered to achieve a
total single dose. In some embodiments, administration of multiple unit
doses is required, or expected to be required, in order to achieve an
intended effect. A unit dose may be, for example, a volume of liquid
(e.g., an acceptable carrier) containing a predetermined quantity of one
or more therapeutic agents, a predetermined amount of one or more
therapeutic agents in solid form, a sustained release formulation or drug
delivery device containing a predetermined amount of one or more
therapeutic agents, etc. It will be appreciated that a unit dose may be
present in a formulation that includes any of a variety of components in
addition to the therapeutic agent(s). For example, acceptable carriers
(e.g., pharmaceutically acceptable carriers), diluents, stabilizers,
buffers, preservatives, etc., may be included as described infra. It will
be appreciated by those skilled in the art, in many embodiments, a total
appropriate daily dosage of a particular therapeutic agent may comprise a
portion, or a plurality, of unit doses, and may be decided, for example,
by the attending physician within the scope of sound medical judgment. In
some embodiments, the specific effective dose level for any particular
subject or organism may depend upon a variety of factors including the
disorder being treated and the severity of the disorder; activity of
specific active compound employed; specific composition employed; age,
body weight, general health, sex and diet of the subject; time of
administration, and rate of excretion of the specific active compound
employed; duration of the treatment; drugs and/or additional therapies
used in combination or coincidental with specific compound(s) employed,
and like factors well known in the medical arts.
[0087] Vasculogenic Mimicry: Those of ordinary skill in the art will
appreciate that the term "vasculogenic mimicry" is often used in the
field to refer to tumor stem cell activity. Vasculogenic mimicry
describes the formation of fluid-conducting channels by highly invasive
and genetically dysregulated tumor cells without participation by
endothelial cells and independent of angiogenesis. Two distinct types are
identified: tubular type and patterned matrix type. The underlying
induction of vasculogenic mimicry seems to be related to hypoxia, which
may promote the plastic phenotype of tumor cells capable of creating this
vasculature.
DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
[0088] The ensuing detailed description provides exemplary embodiments of
the invention, and the disclosure of specific examples is not intended to
limit the scope, applicability, or configuration of the invention.
Guidance provided by this detailed description will permit and enable the
skilled practitioner to put to use all the embodiments of the invention
described herein and covered by the appended claims without undue
experimentation. It will be understood that various changes may be made
to the specific combinations and/or arrangement of the elements or
compounds without departing from the description or coverage of the
claims. Substitution of known equivalents or specific equivalents
disclosed herein, for example for any named component of a pharmaceutical
composition or therapeutic regimen described in the application, is
within the skill of practitioners in the field of this invention.
[0089] In general, the present invention encompasses the recognition that
many processes or pathways in an individual become altered in an
individual suffering from cancer, compared to the same processes or
pathways as they function in normal individuals not suffering from
cancer. The pathways affected by cancer include metabolic pathways (e.g.,
regulation of glucose metabolism, hormone release and uptake, etc.),
intercellular signaling pathways (e.g., regulation of cell proliferation,
migration, circulation as a function of the regulation of cytokines and
growth factors), and intracellular signaling pathways (e.g., differential
gene expression, cell cycle perturbation or arrest, mutation, etc.).
[0090] Table 8 contains a listing of a variety of agents reported to be
involved in pathways that have been found to be altered in patients
diagnosed with cancer:

Apoptotic dysfunction and cell proliferation dysfunction
For example, listed agents are involved in intracellular signal
transduction pathways that drive tumor cell growth and/or in
intracellular signaling pathways that promote angiogenesis, tumor
invasion into normal tissues and the extracellular matrix, and/or tumor
cell metastasis through lymphatic channels and the bloodstream to other
tissues and organs. In some instances, established "cross-talk" or
interaction between certain signaling pathways is deemed so extensive
that it is included as an additional separate pathway.
[0091] The list presented in Table 8 is not in order of importance, among
other things because the relative importance of certain pathways may well
differ, at least to some extent, from patient to patient. Only an
individualized, or "personalized" genomic, molecular, or proteomic tumor
cell analysis would be able to provide insight into which pathways are
relatively more powerful in their contribution to carcinogenesis and
tumor progression in any one patient. In some embodiments, such a
personalized approach may be utilized in selecting a particular regimen
for use in accordance with the present invention, for example through
periodic and/or regular testing of signaling proteins to select and/or
monitor the impact of therapy and optionally to provide direction in
optimizing individualized treatment and/or dosing.
[0092] The disruption of normal metabolic, intercellular signaling, and
intracellular signaling pathways is a characteristic of cancer generally,
although the range of pathways affected and the degree typically varies
with the type of cancer and/or from patient to patient. Nevertheless, the
principles of treatment developed herein are generally applicable;
specific embodiments for treatment of particular tumors and/or patients
can readily be developed and practiced by those skilled in the art,
following the teachings provided herein.
[0093] As described herein, the present invention provides technologies
for addressing multiple pathways involved in cancer through use of
combination therapies. In many embodiments, combinations of therapeutic
agents are selected so that each targeted pathway is addressed at least
twice, and preferably three times, through use of the complete
combination. By "addressed" is meant that the process or pathway will be
altered by the administration of one or more of the composition
components toward normalcy, that is, toward the characteristic function
of that process or pathway in a normal individual, or an individual that
does not suffer from the cancer being treated. Detection of normal or
abnormal functioning of the pathways listed in Table 8 is within the
skill of practitioners in this field.
Failure of Conventional Therapies
[0094] Among other things, the present invention encompasses the
recognition that approximately 50% of all cases are diagnosed after local
invasion or metastasis has occurred (Table 9). and long-term survival is
low in this setting, particularly if distant metastases are present at
the time of first diagnosis.

Stage II, III or IV in 2010 (American College of Surgeons)
[0095] Although significant progress has been made in cancer treatment,
particularly with respect to hematologic malignancies, lymphomas and a
small subset of metastatic solid tumors, the present invention
encompasses the recognition that treatments for most metastatic solid
tumors provide very limited benefit and are extremely expensive. For
example, of twenty-five new US FDA cancer drug approvals for solid tumors
over the past seven years, the average increase in overall survival
and/or progression-free survival in the approval-based trial was 3.4
months (US FDA website). In addition, the average cost per
quality-adjusted life year (QALY) for new cancer drugs is
$200,000-$300,000. With health care expenditures projected to reach 20%
of our gross national product within the next decade, value-equity and
cost-effectiveness considerations for cancer treatment are becoming
problematic (see, for example, Brock Oncologist 15 Suppl 1:36, 2010
PubMed PMID:20237216; Schnipper et al Clin Cancer Res 16(24):6004, 2010
Dec. 15 PubMed PMID:21169254)
[0096] The present invention appreciates that, over the past 50 years
scientists have identified many, if not most, of the genetic alterations
which cause cancer. Approximately 300,000 unique mutations have been
discovered as a result of the sequencing of over 3,000 individual tumors.
Although common solid tumors contain an average of 33-66 gene mutations
that would be expected to alter their protein products, only a small
percentage, called "driver" gene mutations, contribute directly to the
generation and maintenance of the malignant phenotype. Drivers include
genes involved in the stimulation of cell proliferation (oncogenes),
which are mutationally activated or overexpressed, and genes that prevent
inappropriate cell proliferation (suppressor genes), which are
mutationally inactivated or deleted. On average, solid tumor cells
contain at least 3-10 of these "driver" mutations. Hematologic
malignancies (leukemias and lymphomas) average significantly fewer driver
genes, making many of them easier to treat (Vogelstein et al Science
339(6127):1546, 2013 Mar. 29; PubMed PMID 23539594).
[0097] The present invention encompasses appreciation that consolidation
of these findings has led to the concept that cancer results from
deregulation of 8 key hallmarks or cellular pathways (Hanahan et al Cell
100(1):57, 2000 Jan. 7, PubMed PMID: 10647931; Hanahan et al Cell.
144(5):646, 2011 Mar. 4, PubMed PMID:21376230). These pathways involve
proliferation stimulation and suppression (oncogenes and suppressor
genes), invasion and metastasis, replicative mortality, angiogenesis,
programmed cell death or apoptosis, cellular metabolism and energetics,
genomic stability, and immune surveillance.
[0098] According to the present invention, the pathways that are most
important for the survival of tumor cells in metastatic lesions, and
therefore the most therapeutically relevant, are 1) angiogenesis, 2)
apoptosis, 3) cellular metabolism and energetics, and 4) immune
surveillance (Table 10):
TABLE-US-00013
TABLE 10
Hallmark Cancer Pathways: Signifncant
Therapeutically Relevant Targets
Tumor Formation of new blood vessels, and modification
angiogenesis of existing ones
Apoptosis Loss of ability to undergo apoptosis in response
(programmed cell to cellular damage or stress
death or suicide)
Metabilism and Shift from complete oxidation of glucose to
energetics partial oxidation via aerobic glycolysis (Warburg
effect), providing building blocks for cell
proliferation and reducing ROS production
Immune Tumor-mediated inhibition of inate and adaptive
surveillance anti-tumor immune responses, and stimulation of
pro-tumorigenic inflammatory responses
[0099] Moreover, the present invention appreciates that targeting of any
or all of the other pathways will not necessarily lead to tumor cell
death or cell death within a relevant time-frame. For example, the
present invention appreciates that many patients who cannot be cured by
current therapy already have metastatic disease at the time of first
diagnosis, so therapies that prevent invasion or metastasis may slow down
subsequent spread, but cannot be curative. Additionally, the present
invention observes that, since the average doubling time of solid tumors
in patients is 100-400 days and individual tumor cells can divide within
a few days, it is likely that at any one point in time, many cells in a
tumor are either not dividing or are dormant. Thus, drugs targeting
proliferation pathways cannot be expected to kill every tumor cell. Still
further, the present invention appreciates that genomic instability and
replicative immortality associated with cancer are most important during
cancer development and/or operate on a time-scale that is not
therapeutically accessible.
[0100] Modern or "targeted" cancer drug discovery has focused primarily on
the discovery of small molecules or biologics (mainly antibodies) that
interfere with the function of oncogene products. These proteins
generally have an enzymatic activity that can be inhibited by the
therapeutic, and have been referred to as "drugable" targets. The present
invention identifies the source of various problems with such an
approach.
[0101] For example, the present invention appreciates that, as mentioned
above, oncogene-targeted therapeutics may not be efficient at killing
non-dividing or dormant tumor cells. In addition, of 138 identified
cancer-causing driver genes, 64 are oncogenes, but only 31 of these have
a "drugable" enzymatic activity. Moreover, 74 of the 138 drivers are
suppressor genes, where mutation results in functional loss of the gene
product. Such alterations cannot be directly repaired or restored by
small molecule or antibody therapy. Thus, 31+74 or 105 out of 138
currently identified cancer causing genes (76%) fall in the undrugable,
or not easily drugable, category (Vogelstein et al Science
339(6127):1546, 2013 Mar. 29, PubMed PMID: 235395943).
[0102] There is also significant heterogeneity between different types of
cancer, and between tumors of the same histological type isolated from
different patients with respect to what combination (typically about
3-10) driver genes, out of the possible 138, are mutated. Thus, the
present invention observes that a particular pathway may be deregulated
as a result of mutation in an oncogene in one patient, but the same
pathway may be deregulated by an upstream or downstream undrugable
suppressor gene mutation in another patient. Overlap between cellular
pathways may also lead to redundancy across mutations in one tumor. In
this scenario, targeted inhibition of a single oncogene may be
ineffectinve, for example if compensated by another pre-existing mutation
(Vogelstein et al Science 339(6127):1546, 2013 Mar. 29, PubMed PMID:
235395943; Hanahan & Weinberg Cell 100(1):57, 2000 Jan. 7, PubMed PMID:
10647931; Hanahan & Weinberg Cell 144(5):646, 2011 Mar. 4, PubMed
PMID:21376230). The present invention appreciates that these realities
are the source of problems with many conventional chemotherapeutic
treatment strategies.
[0103] The present invention further appreciates another source of a
problem with conventional chemotherapeutic treatment strategies for
cancer: tumor or angiogenic rebound in between doses or after cessation
of treatment with toxic compounds. The present invention provides the
specific insight that these problems highlight a need for effective
therapy, particularly combinations, that can be administered chronically
(i.e. for extended periods).
[0104] The present invention further encompasses the recognition of the
source of problem with many traditional chemotherapeutic treatment
strategies that results from genomic instability of tumors. That is,
tumors undergo additional mutation and selection after treatment is
initiated, resulting in drug resistance via enhanced drug efflux,
metabolism or a compensatory driver mutation. The present invention
appreciates that, even with the use of combinations of oncogene-targeted
and traditional cytotoxic therapies, current drug discovery paradigms,
particularly those focused on treatment of solid tumors, tend to produces
drug that are effective against only one or a few types of cancer, are
only effective in a sub-set of patients with one type of cancer and/or
provide, on average, only 3 additional months of life.
[0105] Still further, the present invention appreciates that the current
regulatory landscape, which was designed primarily to avoid unanticipated
combination or synergistic toxicity in clinical trials involving
non-life-threatening diseases, discourages development of combination
thereapies, particularly when coupled with the extended timeframe
(typically 10-14 years) and daunting pricetag (on average several hundred
million dollars to discover and develop each new cancer drug, with
estimates varying from $43 million to more than $2 billion/drug, Adams &
Brantner Health Aff (Millwood) 25(2):420, 2006 March-April, PubMed
PMID:16522582, DiMasi et al J Health Econ 22(2):151, 2003 March, PubMed
PMID:12606142). Particularly discourages is the development of
combination therapy approaches that utilize agents that are not expected
to be efficacious alone.
[0106] Indeed, the present invention appreciates that various additional
scientific, resource and business constraints have hindered rational or
efficient approaches to combination therapy development in oncology
(Humphrey et al J Natl Cancer Inst 103(16):1222, 2011 Aug. 17, PubMed
PMID:21765011, Levinson Science 38(5975):137, 2010 Apr. 9, PubMed
PMID:20378778, Woodcock et al N Engl J Med 364(11):985, 2011 Mar. 17,
PubMed PMID:21323535). These constraints include the potential for
unacceptable toxicity when combining two conventional chemotherapeutic
agents, because even modern or targeted therapeutics are most active and
typically used individually at their maximum tolerated dose (MTD). In
other words, they have a narrow therapeutic index (TI). Additionally,
there is an historically low predictability of Phase III success with
Phase II combination data, difficulties associated with patient
recruitment (only 3% of cancer patients volunteer for clinical trials),
and hesitation by companies to combine their proprietary investigational
compound with one from another company (Maitland et al Clin Cancer Res
16(21):5296, 2010 Nov. 1, PubMed PMID:20837695). The present invention
encompasses the recognition that these constraints have limited the
development of certain approaches to cancer therapy, and particularly
have led development away from particularly strategies that the present
invention defines as clearly desirable, targeting multiple
therapeutically relevant hallmark pathways (e.g., combinations of
angiogenesis, apoptosis, cellular metabolism and energetics, and immune
surveillance) as described herein.
[0107] Thus, the present invention appreciates that, while much progress
has taken place in the past 40 years, current therapies, led by maximum
tolerated dose chemotherapy, have shown significant limitations in
eliminating the disease progression over longer timeframes and later
stage disease. Moreover, although use of customized cocktails of multiple
targeted agents, or discovery of single drugs with multi-targeting
capabilities, has been discussed in the field, it is an approach that has
not been adequately defined or explored. The present invention provides
specific strategies for tarteging multiple pathways, and furthermore
defines classes of agents, with specific exemplification, that can
effectively be used together to treat cancer.
Targeting Multiple Pathways
[0108] As discussed above, the present invention provides the teaching
that effective cancer therapies utilize a combination of agents that
together target multiple hallmark cancer pathways. In certain
embodiments, a utilized combination includes a collection of agents that
together address each targeted pathway at least twice. In some
embodiments, at least one such pathway is targeted at least three times
by a utilized combination. In some embodiments, each such pathway is
targeted at least twice or at least three times by a utilized
combination.
[0109] Those skilled in the art, reading the present disclosure and its
identification of pathways to be targeted, as well as its teaching of
assembling collections of agents that both target multiple pathways and,
in some embodiments, target individual pathways more than one, will
readily be able to select appropriate agents for combination use in
accordance with the present invention. A variety of strategies for
targeting particular pathways are known in the art and/or described
herein.
[0110] Below, pathways of particular interest for targeting in accordance
with the present invention are discussed in further detail. A
representative strategy for targeting each of these pathways is
illustrated, for example, in FIG. 1:
[0111] Angiogenesis
[0112] "Angiogenesis" refers to the generation of new blood vessels into a
tissue or organ. Under normal physiological conditions, humans or animals
only undergo angiogenesis in very specific restricted situations. For
example, angiogenesis is normally observed in wound healing, fetal and
embryonal development, and formation of the corpus luteum, endometrium,
and placenta. The endogenous control of angiogenesis is a highly
regulated system of angiogenic stimulators and inhibitors. The control of
angiogenesis has been found to be altered in certain disease states and,
in many cases, the pathological damage associated with the disease is
related to uncontrolled angiogenesis.
[0113] Angiogenic regulators in the human or animal body can generally be
divided into two main groups: (1) pro-angiogenic regulators that directly
or indirectly stimulate capillary and blood vessel growth, and (2)
anti-angiogenic regulators or endogenous inhibitors that retard
angiogenesis. Examples of pro-angiogenic regulators include, for example,
Tumor Necrosis Factor (TNF-.alpha.), Granulocyte Colony-Stimulating
Factor (GCSF), and Vascular Endothelial Growth Factor (VEGF). Examples of
anti-angiogenic regulators include, for example, Interferon gamma
(IFN-.gamma.), Thrombospondin-1, endostatin, and angiostatin.
[0114] In many diseases and in cancer in particular, angiogenesis is an
important process that supports the disease, and therefore the process of
angiogenesis itself becomes a target for therapeutic intervention. Recent
medical research has documented the essential role angiogenesis plays in
supporting disease. Angiogenesis is particularly well documented as a
pivotal process in cancer, wherein avascular benign tumors are
transformed into life-threatening malignant tumors.
[0115] Both controlled and uncontrolled angiogenesis are thought to
proceed in a similar manner Endothelial cells and pericytes, surrounded
by a basement membrane, form capillary blood vessels. Angiogenesis begins
with the erosion of the basement membrane by enzymes released by
endothelial cells and leukocytes. The endothelial cells, which line the
lumen of blood vessels, then protrude through the basement membrane.
Angiogenic stimulants (pro-angiogenic regulators) induce the endothelial
cells to migrate through the eroded basement membrane. The migrating
cells form a "sprout" off the parent blood vessel, where the endothelial
cells undergo mitosis and proliferate. The endothelial sprouts merge with
each other to form capillary loops, creating the new blood vessel. In the
disease state, prevention of angiogenesis can avert the damage caused by
the invasion of the new microvascular system.
[0116] Persistent, unregulated angiogenesis occurs in a multiplicity of
disease states, including tumor metastasis and abnormal growth by
endothelial cells, and angiogenesis supports the pathological damage seen
in these conditions. The diverse pathological states created due to
unregulated angiogenesis have been grouped together as angiogenic
dependent or angiogenic associated diseases. Therapies directed at
control of the angiogenic process seek to abrogate or mitigate
development, maintenance, and/or expansion of these diseases.
Angiogenesis has become an important target for cancer treatment with the
recognition that it is one of the critical events necessary for cancer
growth and metastasis. As a tumor develops, its size is limited by the
diffusion of metabolites from existing blood vessels. Tumor angiogenesis
is essential for cancerous tumors to keep growing and spreading.
[0117] As a tumor grows, cells at the center become starved of oxygen,
inducing the expression of a transcription factor, hypoxia inducible
factor-1 (HIF-1), which upregulates the expression of a range of
angiogenic factors. Growth factor signaling also initiates HIF-1
activity, pre-empting the need for growing cells to maintain oxygen
homeostasis. As a result, HIF-1 itself has been isolated as a therapeutic
target for cancer.
[0118] Approximately 9 out of 120 approved cancer drugs target
angiogenesis, predominantly via inhibition of the vascular endothelial
growth factor (VEGF) pathway. Despite initial responses, the clinical
benefits obtained in terms of progression-free survival or overall
survival have been more modest than expected, due to intrinsic or
acquired resistance and possibly also rebound mechanisms. In addition,
combination approaches of anti-angiogenic therapies with
oncogene-targeted or cytotoxic therapies have not produced synergistic
responses in the clinic. A more recent approach, called metronomic
anti-angiogenic therapy, takes advantage of the finding that certain
cytotoxic anti-tumor drugs, such as cyclophosphamide, are anti-angiogenic
when administered daily at low, non-toxic doses (25-41). The present
invention encompasses the recognition that this approach may decrease the
potential for rebound angiogenesis and enhance the potential for
synergism in combination settings.
[0119] In some embodiments, the present invention utilizes metronomic
anti-angiogenic therapy in combination with targeting of other hallmark
pathways, as described herein. In some particular embodiments, the
present invention utilizes metronomic anti-angiogenic therapy with an
agent that also targets another pathway. To give but one example, in some
embodiments, the present invention utilizes metronomic cyclophosphamide;
in addition to its anti-angiogenic effects, metronomic cyclophosphamide
can enhance anti-tumor immune responses.
[0120] Apoptosis
[0121] Normal mammalian cells have a variety of programmed cell death
pathways, designed to induce cellular suicide or apoptosis when cells are
damaged or exposed to sub-optimal conditions. Apoptotic cell death
prevents accumulation of undesirable mutations and, unlike necrotic cell
death, eliminates cells without causing local tissue damage. Many of the
ways that tumors avoid engagement of apoptosis pathways are
well-understood, frequently involving overexpression of apoptosis
inhibitor proteins (42-43).
[0122] Although more difficult to target than enzymes involved in cell
proliferation and angiogenesis, a number of drugs are under development
in this area. The present invention recognizes a potential pitfall in
this approach, and particularly in the understandinble incentive to
combine pro-apoptptic agents with existing anti-proliferative agents.
That is, the present invention appreciates that over-expression of
proteins which inhibit apoptosis allows the tumor cell to continue to
accumulate mutations and to divide in an uncontrolled fashion.
Pharmaceutical approaches to reverse this increasing insensitivity to
apoptosis should cause the tumor cell to be more susceptible to the
programmed cell death pathways. Given the propensity in cancer therapy to
combine agents for added benefit, it would seem logical to also treat the
patient with cytotoxic, apoptosis-inducing agents. The present invention
appreciates, however, that, paradoxically, these cytotoxic agents at high
doses cause a delay in cell cycle progression. Thus, cells which survive
the cytotoxic insult are more likely to be temporally non-proliferating
and less sensitive to apoptosis inducing stimuli. Therefore, in
accordance with the present invention, it is possible that certain
pro-apoptotic drugs will work best under conditions where tumor cells are
actively trying to divide, rather than against dormant or non-dividing
cells. In some particular embodiments of the present invention,
anti-proliferative agents are not utilized in combination with
pro-apoptotic agents. In some embodiments, pro-apoptotic agents are used
in combination with one or more agents that promotes or supports cell
proliferation. In some embodiments, however, patients are treated with
both anti-proliferative and pro-apoptotic agents.
[0123] Immune Surveillance
[0124] The potential for induction of anti-tumor immune responses (immune
surveillance) has been appreciated for over 100 years, but the
fundamental mechanisms by which tumors evade immune destruction have only
recently been elucidated. It is now clear that tumors express and secrete
factors that shift the balance of the innate or inflammatory immune
response from anti-tumorigenic to pro-tumorigenic. This is accomplished
by suppressing anti-tumor natural killer (NK) cell and cytotoxic T
lymphocyte (CTL) function, and enhancing general pro-inflammatory
responses which stimulate tumor growth and tumor angiogenesis. In
addition, despite the fact that tumors express, on average, 33-66 mutant
proteins, several of which should be recognizable as foreign antigens,
tumors block antigen presentation, as well as induction and maturation of
adaptive immune responses (44).
[0125] Elucidation of these immune surveillance mechanisms has resulted in
the development and approval of at least one therapeutic (ipilimumab),
which directly stimulates anti-tumor immune responses. This compound has
produced long-term responses in a sub-set of malignant melanoma patients,
but is also associated with significant toxicity, due to activation of
auto-immune responses in normal tissues (45).
[0126] Thus, the present invention appreciates that it is possible to
restore immune surveillance in cancer patients. The present invention
further recognizes that combination of agents that hit related immune
response mechanisms and other pathways will significantly increase
response rate.
[0127] Metabolism and Energetics
[0128] Aberrant metabolism related to energy production was first
described in tumor cells almost 90 years ago by Otto Warburg, who
observed that tumors have a higher than normal rate of aerobic
glycolysis. The reasons for this have only recently become apparent
(46-50). Most normal epithelial cells are not actively dividing.
Non-dividing cells in normal tissues have minimal requirements for
catabolic intermediates, have a plentiful oxygen supply and thus, can
afford to fully oxidize glucose via glycolysis and the tricarboxylic acid
cycle (TCA), and then use the NADH and FADH generated to make ATP by
oxidative phosphorylation. This strategy is more efficient than
glycolysis with respect to ATP production, but results in loss of
glycolytic and TCA intermediates that could otherwise be used in anabolic
pathways to make ribose sugars for nucleotides, lipids, and amino acids
for proteins. Production of ATP by oxidative phosphorylation is also
100-times slower than glycolysis-driven ATP production. In addition,
oxidative phosphorylation generates reactive oxygen species (ROS), which
can damage cellular constituents, leading to apoptosis.
[0129] Normal cells have several anti-oxidant mechanisms, don't need to
continually make large amounts of DNA, RNA, lipid or protein, and can
afford to make ATP relatively slowly. Tumor cells, on the other hand,
divide more frequently than normal cells, requiring significantly larger
pools of DNA, RNA, lipid and protein precursors. Although a significant
amount of lactic acid and only 2 net ATPs are produced via glycolysis,
rapid turnover can satisfy cellular energy requirements and lactic acid
can be recycled to glucose in the liver. Use of glycolytic pathways for
metabolism allows tumor cells to produce the large amounts of precursors
needed for uncontrolled cell proliferation. Also, by de-emphasizing
oxidative phosphorylation, tumor cells can reduce production of ROS.
Reducing ROS is important for tumor cells because they not able to repair
and recover from non-specific oxidative damage as easily as normal cells.
Finally, tumors are continuously exposed to hypoxic (low oxygen)
conditions as they grow and struggle to induce formation of new blood
vessels. Decreasing their reliance on oxygen-dependent oxidative
phosphorylation provides tumor cells with an additional survival
advantage in this setting.
[0130] During the past decade, it has been found that the shift from
oxidative phosphorylation-based energy production to an aerobic
glycolysis-based approach in tumor cells requires a large number of
primary and secondary alterations in multiple pathways, including those
involved in cell proliferation, apoptosis and angiogenesis. For example,
mutational activation of certain oncogenes leads, among other things, to
increased expression of a glucose transport protein that is required to
accumulate sufficient glucose to power anaerobic glycolysis (51). The
oncogenes and the glucose transporter are components of the mammalian
target of rapamycin (mTOR) signaling pathway that integrates signals
controlling protein biosynthesis, cell growth, cell cycle progression,
energy metabolism, angiogenesis and apoptosis (52-54). Since this pathway
is centrally involved in energy metabolism, including glucose utilization
and production, it is not surprising that it also plays a role in the
etiology and treatment of type 2 diabetes.
[0131] The present invention encompasses the recognition that it is
desirable to treat cancer by targeting metabolism and/or energetics
pathways in tumor cells, particularly while targeting other pathways, as
described herein. The present invention particularly observes that
metformin, a well-tolerated first-line drug of choice used to suppress
glucose production in type 2 diabetes, has also been found to reverse
several of the aberrant metabolic features of tumor cells (55-67).
Agents for Use in Inventive Therapeutic Regimens
[0132] As described herein, it has become clear that hallmark cancer
pathways overlap and cooperate with each other, looking much like the
subway map from a large city. Three to ten very specific mutations or
defects among the many hundreds of "stations in the system" can be
sufficient to turn a normal cell into a cancer cell. Redundancy and
genomic instability, leading to drug resistance and/or new cancer causing
mutations can compensate quickly when one or perhaps even two defects are
corrected by targeted therapeutics. On the other hand, it is
statistically much more likely that any two or more pathway interventions
will cause an unacceptable breakdown of the system in normal cells, than
selective killing of tumor cells, because normal cells require and use
all of the same pathways, but without the benefits of genomic
instability.
[0133] In light of these realities, the present invention identifies
sources of problems with conventional approaches to the development
and/or implementation of strategies for the treatment of cancer. As
described herein, approaches that individually target proliferation
stimulation and suppression (oncogenes and suppressor genes), invasion
and metastasis, replicative mortality, angiogenesis, programmed cell
death or apoptosis, cellular metabolism and energetics, genomic
stability, and immune surveillance, may be ineffective against particular
cancer cells, including for example cells that may be in a dormant state,
or cells that arise in late stage (e.g., metastasized) cancers.
Conventional focus on "druggable" significantly restricts options.
Moreover, the typical reliance on narrow-therapeutic-index agents,
usually utilized at or near their maximum tolerated dose, complicates or
even prevents development of effective combination therapies through
conventional strategies.
[0134] The present invention provides new and improved strategies for
developing and/or implementing cancer therapy. Among other things, the
present invention appreciates the benefits of targeting multiple
pathways, and furthermore appreciates that combinations of particular
interest both target multiple pathways and target individual pathways in
multiple ways.
[0135] Moreover, the present invention encompasses the recognition that in
certain embodiments it is desirable to utilize agents (and/or dosing
regimens) with a broader therapeutic index than that commonly observed
for conventional chemotherapeutic agents. Such conventional agents are
typically characterized by a therapeutic index within the range of about
2 to about 5. In some embodiments, the present invention utilizes one or
more agents whose therapeutic index is within the range of about 10 to
about 100.
[0136] The present invention encompasses the particular insight that
therapeutic agents developed for and/or effective in treatment of certain
non-life-threatening conditions, and particularly of chronic conditions,
may target one or more pathways that, as described herein, are hallmark
cancer pathways, and may be useful in combination therapies as described
herein. Such agents typically show a wide safety margin, particularly
when developed for long-term therapy. Indeed, agents approved for
long-term therapy of non-life-threatening diseases, disorders, or
conditions typically have had to meet stringent regulatory risk-benefit
requirements. The lower the morbidity associated with the condition being
treated, the lower the acceptable risk for its therapy. In accordance
with certain embodiments of the present invention, agents developed for
treatment of low-morbidity, chronic illnesses that target one or more
hallmark cancer pathways as described herein are particularly useful in
inventive therapeutic regimens for the treatment of cancer.
[0137] Still further, the present invention encompasses the recognition
that certain traditional and/or nutraceutical medicine approaches,
including complementary and alternative medicines (CAM) identify and/or
utilize well-tolerated agents that target the relevant pathways described
herein. In many embodiments, such agents may be or include purified or
partially purified natural products or extracts. In some embodiments,
such products have been identified and/or characterized as a result of
decades, or even centuries, of observational trial and error. Typically,
traditional and/or nutraceutical agents are well tolerated (i.e., are
associated with minimal toxicities), and show high therapeutic indices
(e.g., typically well above 10, and often within the at least 10 to at
least 100 range described herein, sometimes even higher).
[0138] Among other things, therefore, the present invention provides
cancer therapies that utilize combinations of agents that show high
therapeutic indeces and/or together target multiple allmark cancer
pathways, preferably in multiple ways.
[0139] In some embodiments, natural compounds and supplements referred to
as "Nutraceuticals", "Natural Medicines", or "Phytomedicines" are
suitable for use in combination therapies of the invention. As described
herein, such nutraceuticals may be selected based on the quality and
number of preclinical or clinical studies presenting either credible
evidence of clinical anti-tumor activity in human cancer patients or
demonstrating their ability to affect one or more tumorigenic and
angiogenic signaling pathways described herein, and/or to interfere with
the noted "cross-talk" between pathways that is essential for tumor cells
to proliferate, for angiogenesis to flourish, and for tumor progression.
[0140] In some embodiments, combination therapies of the present invention
may include, in addition to one or more nutraceutical compounds, any of a
number of non-chemotherapeutic or chemotherapeutic drugs for their
desired effects on metabolic or signaling pathways. Such
non-chemotherapeutic or chemotherapeutic drugs may address the same
pathway(s) as nutraceutical components of a composition of the invention
or may address pathways not adequately altered by administration of
nutraceutical components. As these components are drugs and thus subject
to regulations, they normally may only be included by order of a
physician or qualified and licensed healthcare practitioner. Exemplary
non-chemotherapeutic drugs include but are not limited to Metformin,
Cyclophosphamide, Naltrexone, Melatonin, and others. Those of ordinary
skill in the art will appreciate that some or all of these agents may, in
some embodiments, be utilized in accordance with their approved drug
regimens or protocols. Alternatively or additionally, in some
embodiments, these agents are or may be utilized at different doses,
and/or according to different regimens or protocols than those for which
they have been approved. In some embodiments, such doses and/or regimens
or protocols are known and/or established in the art. In some
embodiments, order of a physician or qualified and licensed healthcare
practitioner may not be required for such administration. For example,
those skilled in the art will appreciate that melatonin has a variety of
well-established uses (including as otherwise described herein), some but
not all of which have been subject to formal regulatory approval. In some
embodiments, one or more non-chemotherapeutic drugs are chosen as
significant components of the methods and compositions described herein,
based on research demonstrating their capacity to suppress or disrupt key
signaling pathways involved in cancer, more particularly for the
treatment of epithelial cell related cancers cancer. The evidence
supporting their anti-cancer efficacy varies from agent to agent, but in
almost all cases there is sound published evidence of anti-cancer
activity, and in some cases anti-angiogenic activity.
[0141] Clinical trials mostly offer access to Phase I or II studies of
targeted therapies that, again, may target just one marker, or in some
cases, several markers. Currently approved cancer therapies typically
involve the selection of a single chemotherapeutic agent found to have a
direct impact on cancer cell growth and administering as much of that
agent as can be tolerated by the patient without being fatally toxic. One
concept embodied by the present invention is that by addressing only one
pathway with a chemotherapeutic drug leaves several other
cancer-supportive pathways unchecked or cancer-suppressive pathways
unenhanced, which may leave the cancer alternative pathways of
angiogenesis, growth, or migration. By contrast, with inventive
therapeutic protocols described herein, although potency of particular
individual agents (e.g., natural compounds and/or non-chemotherapeutic
drugs) against any one target may be less than that of a rationally
designed pharmaceutical, the combination of multiple agents (and
particularly of multiple natural compounds [e.g., Nutraceuticals] and/or
non-chemotherapeutic pharmaceuticals), preferably including multiple
agents against individual target pathways, has the potential to address
multiple pathways with multiplicative pharmacologic potencies.
[0142] In some embodiments, provided inventive therapeutic regimens
utilize only nuctraceutical agents and/or agents developed and/or
approved for non-cancer conditions (e.g., non-chemotherapeutic agents).
In some embodiments, provided inventive therapeutic regimens utilize at
least one agent that has been approved for treatment of one or more
cancers; in some such embodiments, such agents is utilized in accordance
with the present invention according to a dosing regimen that is
different from the approved cancer treatment regimen. In some
embodiments, such different regimen involves administration of lower
individual doses and/or lower overall exposure over a period of time, as
compared with a reference (e.g., approved) cancer therapeutic regimen
utilizing the same agent.
[0143] Exemplary agents useful for inclusion in certain embodiments of
inventive combination therapy regimens for the treatment of cancer are
discussed individually below. For many of them, there are a number of
equivalent agents that will be known to those skilled in the art.
[0144] Nutraceutical and/or Non-Chemotherapeutic Agents
Alpha-Lipoic Acid
[0145] Alpha-Lipoic Acid is a fatty acid produced by the body for
converting glucose into energy. It is also known to have antioxidant
properties beneficial for fighting harmful chemicals that contribute to
onset of disease. It is also referred to by the following names: Acetate
Replacing Factor, A-Lipoic Acid, Acide Alpha-Lipoique, Acide
Alpha-Lipoique R, Acide DL-Alpha-Lipoique, Acide Lipoique, Acide
Thioctique, Acide 1,2-dithiolane-3-pentanoique, Acide
1,2-dithiolane-3-valerique, Acide 5 Valerique (1,2-dithiolan-3-yl), Acide

(R)-Lipoic Acid, R-Lipoic Acid, RS-Alpha-Lipoic Acid Thioctacid,
Thioctan, Thioctic Acid, 1,2-dithiolane-3-pentanoic acid,
1,2-dithiolane-3-valeric acid, 6,8-dithiooctanoic acid, 6,8-thioctic
acid, 5-(1,2-dithiolan-3-yl) valeric acid.
[0146] Although manufactured by the body and found in trace amounts in
foods such as spinach, broccoli, peas, Brewer's yeast, brussel sprouts,
rice, bran, potatoes and organ meats (kidney, heart, liver), it is the
concentrated amounts of Alpha-Lipoic Acid found in supplements that
provides the best antioxidant effect. When produced endogenously in
plants or humans, it is complexed with proteins. However, when taken in
supplement form, it is not bound to proteins and is likely in a 1000 fold
greater amount than can be obtained through regular diet.
[0147] Alpha-Lipoic Acid is known to inhibit TNF-.alpha.-induced NF-kappaB
pathway activation which leads to endothelial activation and monocyte
adhesion, which are the initial steps to leading to inflammation caused
by oxidative stress. Alpha-Lipoic Acid has also been found to inhibit
copper- and iron-mediated oxidative damage and accumulation via chelation
of free metal ions. This process suppresses the induced oxidative damage
caused by reactions that produce reactive free radicals. The addition of
Alpha-Lipoic Acid to cultured cells has been shown to activate
PKB/Akt-dependent signaling resulting in increased survival of neurons.
[0148] Several Alpha-Lipoic Acid supplements are presently manufactured.
It is important to note that Alpha-Lipoic Acid contains an asymmetric
carbon, meaning there are two possible optical isomers that are mirror
images of each other (R- and S-isomers). Most supplements may contain a
50/50 racemic mixture of each R-Alpha-Lipoic Acid and S-Alpha-Lipoic
Acid. Supplements that contain only the R-isomer are available but the
level of purity may be uncertain. Since taking Alpha-Lipoic Acid with a
meal decreases its bioavailability, it is generally recommended that it
be taken on an empty stomach (one hour before or two hours after eating).
[0149] Commercial suppliers for ALA include Source Naturals Alpha Lipoic
Acid, Swanson Ultra Alpha Lipoic Acid, NOW Foods Alpha Lipoic Acid,
Bluebonnet Alpha Lipoic Acid, Country Life R-Lipoic Acid, Solgar Alpha
Lipoic Acid.
[0150] Curcumin
[0151] The active ingredient in the spice Turmeric is curcumin, which is
extracted from the rhizome of the plant curcuma longa Linn. Curcumin is
the principal curcuminoid, or polyphenolic compound found in such
extracts, with others including demethoxycurcumin and
bisdemethoxycurcumin.
[0152] Turmeric is also known as Curcuma, Curcuma aromatica, Curcuma
domestica, Curcumae longa, Curcumae Longae Rhizoma, Curcumin, Curcumine,
Curcuminoid, Curcuminoide, Curcuminoides, Curcuminoids, Halada, Haldi,
Haridra, Indian Saffron, Nisha, Pian Jiang Huang, Racine de Curcuma,
Radix Curcumae, Rajani, Rhizoma Cucurmae Longae, Safran Bourbon, Safran
de Batallita, Safran des Indes, Turmeric Root, Yu Jin.
[0153] Curcumin's mechanisms of action include inhibition of several cell
signaling pathways, effects on cellular enzymes such as cyclooxygenase
and effects on angiogenesis and cell-cell adhesion. Curcumin also affects
gene transcription and induces apoptosis.
[0154] Curcumin is effective at inhibiting the signal transduction pathway
of PI3K/Akt, MAPK, and NF-.kappa.B activation, as well as the Sonic
Hedgehog (Shh) signaling pathway by down-regulating the Shh protein. In
turn, reduction of beta-catenin, the activated/phosphorylated form of Akt
and NF-.kappa.B, triggers apoptosis.
[0155] The oncogenic pathways inhibited by curcumin include
down-regulation of epidermal growth factor receptors (EGFR and erbB2),
Insulin-like growth factor type-1 receptor (IFG-1R), sonic hedgehog
(SHH)/GLIs) and Wnt/b-catenin and PARP, IKK, EGFR, JNK, MAPK and 5-LOX.
In addition curcumin suppresses downstream signaling elements such as
signal transducers and activators of transcription (STATs), PI3K/Akt,
nuclear factor-kappa B (NF-.kappa.B), and its targeted genes, including
IL-6, COX-2, and MMPs.
[0156] Curcumin is most beneficial when take in liposomal form. The most
bioavailable supplement is Life Extension's Super Bio Curcumin.RTM. which
absorbs into the bloodstream up to seven times better than conventional
95% curcumin extract. Alternatively or additionally, another highly
bioavailable form of Curcumin is Euromedica CuraPro BCM-95.RTM. or
Progressive Labs Curcumin BCM-95.RTM.. Other curcumin supplements add
piperine, (Piper nigrum) to enhance absorption of curcumin in their
products. However, the interactions of piperine with many medications can
cause problems including toxicity if taken in high doses. Curcumin can
exist in the tautomeric forms that include the 1,3-diketo and the enol
form. The most stable form of Curcumin is its planar enol form.
Additionally Biomar.TM. Curcumin is commercially available.
[0157] Alternatives to Super Bio-Curcumin and/or Euromedica BCM-95.RTM.
include all 95% Curcumin supplements including Jarrow Formulas Curcumin
95, NOW Foods Curcumin, Genceutic Naturals Curcumin BCM-95, etc.
[0158] Turmeric Extract in fact only provides 2-6% curcumin, and it can be
important to take Curcumin in higher levels. Any supplement that is lower
than 95% Curcumin is not as effective. Only about 50-60% is absorbed (in
contrast to 96% absorption with Super Bio Curcumin.RTM.) In addition,
dilutions with other supplements such as bioperine reduce
bioavailability, and as mentioned piperine can interact with other
medications negatively. Synthetic, petroleum-derived curcumin supplements
may only contain on or two of the important curcuminoids found in natural
supplements. Resveratrol is not a substitute. There are "Ultimate
Antioxidants" that contain Curcumin and other important antioxidants, but
do not reach the quality or bioavailability of other supplements (e.g.
Natural Factors.RTM.Ultimate Antioxidant claims 95% total curcuminoids,
but does not specify which, and has 13 other factors that may or may not
be beneficial).
[0159] In some embodiments, when administering Curcumin, consideration may
desirably be given to factors impacting a patient's ability to absorb
administered material. For example, if may be desirable or necessary to
reduce or eliminate one or more Curcumin otherwise desirable or
appropriate Curcumin doses if a patient has suffered damage (including,
for example, removal by surgery; see Examples) of part of his or her
gastrointestinal tract. Alternatively or additionally, it might be
desirable to administer Curcumin in a more palatable or bioavailable form
(e.g., as a liquid) to certain patients.
[0160] Genistein
[0161] Genistein is an isoflavone extracted from fermented soy. It is also
referred to as Basidiomycetes Polysaccharide, Fermented Genistein,
Fermented Isoflavone, GCP, Genistein Polysaccharide, Genisteine du
Polysaccharide Combine, Isoflavone Combined Polysaccharide, Polysacaridos
Combinados de Genisteina, and Soy Isoflavone Polysaccharide.
[0162] Genistein plays an important role in reducing the incidence of
breast and prostate cancers. It has been shown that genistein inhibits
the activation of NF-kappaB and Akt signaling pathways, both of which are
known to maintain a homeostatic balance between cell survival and
apoptosis. Furthermore, genistein has been found to have antioxidant
properties, and shown to be a potent inhibitor of angiogenesis and
metastasis. In addition, genistein works to target endogenous copper
which leads to pro-oxidant signaling and consequent cell death.
[0163] Genistein has also been shown to downregulate the IGF-1/IGF-1R
signaling pathway and inhibit cell growth in hormone refractory PC-3
prostate cancer cells. Treatment with Genistein resulted in a significant
inhibition of IGF-1-stimulated cell growth. Treatment with Genistein also
strongly attenuated IGF-1-induced .beta.-catenin signaling that
correlated with increasing the levels of E-cadherin and decreasing cyclin
D1 levels in PC-3 cells. In addition, genistein inhibited T-cell
factor/lymphoid enhancer factor (TCF/LEF)-dependent transcriptional
activity.
[0164] Genistein has also been shown to inhibit VEGF-induced endothelial
cell activation by decreasing PTK activity and MAPK activation, resulting
in anti-angiogenic activity. Exposure to genistein also decreased
activation of JNK and p38, not ERK-1/2, induced by VEGF. It also
inhibited activity of MMPs.
[0165] Genistein is readily bioavailable. The purest form is commercially
available in 99% purity from laboratories including LC Labs, Enzo Life
Sciences, BioVision. However, not all forms are suitable for human
consumption. Less preferable sources are the soy isoflavone supplements
that contain genistein at lower concentrations.
[0166] Melatonin
[0167] Melatonin is a hormone secreted by the pineal gland and found
naturally in the body. Melatonin is also synthetically produced in a
laboratory for medical use. It is also referred to as MEL, Melatonina,
Melatonin, MLT, N-acetyl-5-methoxytryptamine,
N-Acetyl-5-Methoxytryptamine, and Pineal Hormone.
[0168] Melatonin has known, potent anti-oxidant, anti-inflammatory, and
anti-tumor properties, but it also influences oncogenic pathways
including mTOR, which plays a role in pancreatic cancer. Melatonin
induces pro-apoptotic signaling in pancreatic cancer cells; restores
mitochondrial function which in turn restores apoptosis of pancreatic
cancer cells; and enhances patients' responses to Capecitabine (XELODA).
Leja-Szpak, et al., J Pineal Res., 49(3):248-55 (2010); Gonzalez, et al.,
J Pineal Res., Epub 2010; Ruiz-Rabelo, et al., Pancreas, Epub 2010.
[0169] Melatonin is known to suppress tumor angiogenesis by inhibiting
HIF-la stabilization under hypoxia, leading to a decrease in VEGF
expression. Melatonin also inhibits cell proliferation and migration of
HUVECs and also decreases both the VEGF protein secreted and the protein
produced by pancreatic carcinoma cells. In addition, VEGF mRNA expression
is known to be down-regulated by melatonin. Melatonin has also been shown
to inhibit cell proliferation and induce apoptosis in cancer cells in
vitro by simultaneously suppressing the COX-2/PGE2, p300/NF-.kappa.B, and
PI3K/Akt/signaling and activating the Apaf-1/caspase-dependent apoptotic
pathway.
[0170] The most beneficial form of Melatonin is in pharmaceutical grade
(not "natural", animal, or bovine) supplements having a purity of 99% or
greater. The bioavailability of melatonin varies widely. A bioavailable
source is Thorne Research Melatonin-5.TM.. Melatonin has several clinical
analogs that bind to melatonin receptors, but ultimately have a different
function (most commonly as a sleep aid only or antidepressant only).
These include 520242, agomelatine, and 2-Bromomelatonin. When melatonin,
ramelteon, tasimelteon, PD-6735, and agomelatine are compared,
agomelatine is the analogue that exhibits the most potential for the
treatment of major depression. Unlike melatonin, agomelatine is a
competitive antagonist of human and porcine serotonin (5-HT2C) receptors
and human 5-HT2B receptors.
[0171] Alternatively or additionally, there are medications that include
impurities and low levels of melatonin, for example, Circadin used for
insomnia. Melatonin should only be taken in synthetic (man-made) form.
The alternative that is extracted from ground-up cow pineal glands is
rarely used, as it may spread disease.
[0172] Melatonin is reported to be useful in the treatment of a variety of
diseases, disorders, and conditions, and recommended dosing regimens
include, for example:
[0173] For age-related macular degeneration (vision loss with age), three
milligrams of melatonin have been taken by mouth nightly at bedtime for
six months.
[0174] To improve body temperature regulation in the elderly, 1.5
milligrams of melatonin has been taken by mouth nightly for two weeks.

[0191] For headache, 2-10 milligrams of melatonin has been taken by mouth
nightly for 14 days to eight weeks.
[0192] For liver inflammation, five milligrams of melatonin has been taken
by mouth twice daily for 12 weeks.

[0194] For high cholesterol, five milligrams of melatonin has been taken
by mouth daily for two months.
[0195] For insomnia in the elderly, melatonin has been taken by mouth in
doses of 0.1-5 milligrams at or two hours before bedtime for up to
several months, in the form of melatonin-rich night milk or slow-release
Circadin.RTM.. A dose of 0.5 milligrams has been placed in the cheek for
four nights.
[0196] For jet lag, 0.1-8 milligrams of melatonin has been taken by mouth

mouth nightly at bedtime for 3-6 months.
[0199] For Parkinson's disease, doses of 3-50 milligrams have been taken
by mouth nightly before bed for 2-10 weeks. (High doses of 3-6.6 grams of
melatonin have also been taken by mouth daily; however, these doses were
used in an older 1972 study and are no longer in use.)
[0200] For periodic limb movement disorder, three milligrams of melatonin
has been taken by mouth nightly for six weeks.
[0201] For REM sleep behavior disorder, 3-12 milligrams of melatonin has
been taken by mouth daily for four weeks.
[0202] For restless leg syndrome, a single dose of three milligrams of
melatonin has been taken by mouth.
[0203] For sarcoidosis (chronic widespread inflammation), 20 milligrams of
melatonin has been taken by mouth daily for one year, then decreased to
10 milligrams for a second year.
[0204] For muscle movement problems in people with schizophrenia, 2-10
milligrams of melatonin has been taken by mouth daily.
[0205] For seasonal affective disorder (SAD), two milligrams of
sustained-release melatonin has been taken by mouth 1-2 hours nightly for
three weeks. A dose of 0.5 milligrams of melatonin has been taken under
the tongue for six days.

form of a gel (20-100 milligrams of melatonin in 70% ethanol, in
concentrations of 0.05-0.5% in 0.12 milliliters of gel); 0.6 milligrams
per meter squared from 15 minutes before to 240 minutes after sun
exposure, alone or with vitamins C and E; five percent melatonin in
ethanol, propylene glycol, and water; and 5.85 microliters of solutions
containing 1.2-5% melatonin, alone or with vitamins C and E.
[0234] Melatonin can impact on circadian rhythm differently depending on
the time of day at which it is taken, so that attention is typically
given to the timing of melatonin dosing.
[0235] In accordance with embodiments of the present invention, suitable
amounts of Melatonin will be 0.3-75 mg, preferably 1.0-50 mg, more
preferably 1.0-20 mg, more preferably 1.0-10 mg, more preferably 2.0-10
mg per day. Most preferably the dosage amounts will range between 0.3 mg
and 5.0 mg, between 1.0 mg and 5.0 mg, or between 3.0 mg and 6.0 mg, with
all or part of the dose being administered at night/bedtime. Particularly
preferred dosages will be 3.0-6.0 mg nightly, or 10-50 mg nightly in
severe cases.
[0236] Metformin
[0237] Metformin is a pharmaceutical compound initially indicated for
diabetes and has the following brand names: Glucophage, Riomet.RTM.,
Fortamet, Glumetza. Approved dosing regimens for diabetic patients are
individually tailored, with maximum recommended daily dosages set at 2550
mg for adults or 2000 mg for pediatric patients. Typically, clinically
significant responsses are not seen at doses below 1500 mg/day. However,
therapy is typically initiated with a lower starting dose (e.g., 500 mg
once or twice/day or 85-mg/day), with gradually increasing subsequent
doses (e.g., increasing in increments of 500 mg/week or 850 mg/2 weeks)
[0238] Metformin modulates the mTOR pathway, which antiproliferative
effects during treatment with paclitaxel.
[0239] Metformin also functions in reducing cell growth, protein
synthesis, MAPK3/1, and P90RSK phosphorylation in response to IGF1
through an AMPK-dependent mechanism in cultured bovine granulosa cells.
In addition, Metformin strongly inhibited the proliferation, migration,
and MMP-2 and -9 expression of HUVECs, also partially AMPK-dependent.
Metformin also inhibits cell proliferation, migration and invasion
through reexpression of miRNAs and decreased expression of CSC-specific
genes, which suggests that Metformin could be useful for overcoming
therapeutic resistance of cancer cells, including, for example,
pancreatic cancer cells or cells of other epithelial cell cancers.
[0240] The present invention recognizes at least two main lines of
evidence that suggest that Metformin's primary target is the
immortalizing step during tumorigenesis. First, Metformin activates
intracellular DNA damage response checkpoints. Second, Metformin
attenuates the anti-senescence effects of the ATP-generating glycolytic
metabotype, i.e., the Warburg effect, which is required for self-renewal
and proliferation of CSCs. If Metformin therapy presents an intrinsic
barrier against tumorigenesis by lowering the threshold for
stress-induced senescence, then the present invention teaches that
Metformin therapeutic strategies may be pivotal for therapeutic
intervention for cancer.
[0241] Sources of Metformin include Metformin hydrochloride, which is a
derivative of metformin present in Riomet (brand name analogs
Apo-Metformin, Fortamet, Gen-Metformin, Glucophage, Glucophage XR,
Glycon, Metformin HCL, Novo-Metformin, Nu-Metformin). Brand names of
combination products include Actoplus Met (Metformin and pioglitazone),
Avandamet (Metformin and rosiglitazone), Glucovance (Metformin and
Glyburide), Janumet (Metformin and sitagliptin), Kombiglyze (Metformin
and saxagliptin), Metaglip (Metformin and Glipizide), PrandiMet
(Metformin and repaglinide), all of which have different clinical
implications.
[0242] Low doses of Metformin have shown multiple pathway effects against
cancer. Among its most important potential roles in cancer therapy is
Metformin's capacity to improve insulin sensitivity, which results in a
reduction in insulin levels and a marked reduction in the quantity and
activity of Insulin Growth Factor-1 (IGF-1), which is a critical driver
of malignant growth in pancreatic cancer. (Bao, et al., Biochem Biophys
Acta., Epub (2010)) Researchers from UCLA have identified cross-talk
between insulin/IGF-1 and GPCR signaling systems as a key to pancreatic
cancer growth, and since Metformin has been shown to block this
cross-talk, they propose Metformin as a promising candidate for
pancreatic cancer prevention and treatment. Rozengurt, et al., Clin
Cancer Res., 16(9):2505-11 (2010). There is also evidence that Metformin
assists in a shift from aerobic glycolysis (the "Warburg Effect") to
glucose oxidation, which results in restoration of normal mitochondrial
function that, in turn, triggers a renewed capacity for undergoing
apoptosis. Martinez-Outschoorn, et al., Cell Cycle, 9(16):3256-76 (2010).
[0243] In embodiments of the present invention, a Metformin dosage regimen
will be designed by the attending physician to address the particular
metabolic pathways implicated in the disease, for the particular patient,
bearing in mind, of course, that in selecting the appropriate dosage in
any specific case, consideration must be given to the patient's weight,
general health, age, and other factors which may influence response to
the drug. In general, in a composition according to the invention for
treating cancers of epithelial origin cancer, the dosage range will be
50-2000 mg/day, preferably 500-1000 mg/day. Alternatively, doses of 100
mg, 250 mg, 500 mg, 625 mg, 750 mg, 850 mg, or 1000 mg from one to four
times a day, or similar dosing regimens, may be administered.
[0244] N-Acetyl Cysteine
[0245] The active ingredient N-Acetyl Cysteine (NAC) is derived from the
amino acid L-cystein. It is a more stable form of Cysteine that can be
taken as a supplement. Cysteine is an essential amino acid required for
the production of glutathione, a free radical fighter.
[0246] NAC is also referred to as: Acetyl Cysteine, Acetyl Cysteine,
Acetylcysteine, Acetylcysteine, Chlorhydrate de Cysteine, Cysteine,
Cysteine, Cysteine Hydrochloride, Cystine, Hydrochlorure de Cysteine,
L-Cysteine, L-Cysteine, L-Cysteine HCl, L-Cysteine HCl, NAC, N-Acetil
Cisteina, N-Acetyl-B-Cysteine, N-Acetyl Cysteine, N-Acetyl-L-Cysteine,
N-Acetyl-L-Cysteine, N-Acetylcysteine, and N-Acetylcysteine.
[0247] NAC has been associated with diminished oxidative stress reflected
in preserved antioxidant levels and lower inflammation reflected in lower
interleukin levels. NAC is also effective to maintain Vitamins C and E in
their reduced state, enhancing their effectiveness which in turn makes
the produced glutathione more effective. It is also known to prevent
apoptosis through inverse regulation of NF.kappa.B and INK pathways and
inducing differentiation of the cells. By suppressing the NF-kappa B
pathway, it also represents an attractive therapeutic target for
treatments to control neutrophilic inflammation. Treatment of certain
carcinomas with NAC monitors expression of the COX-2 protein, inducing
apoptosis. It is predicted that this could be effective as a predictor of
chemoresistance and that assessment of the COX-2 status could be
advantageous to identify cervical cancer patients who may benefit from
NAC administration. NAC has also been shown to inhibit both COX-2
expression and NF-kappaB nuclear translocation, which in turn is
suggestive that NAC could inhibit the inflammatory process.
[0248] NAC is most beneficial (bioavailable) when administered in
liposomal form. It is important to use pharmaceutical grade NAC (e.g.
Swanson Ultra Pharmaceutical Grade Ajupure.RTM. N-Acetyl L-Cysteine).
[0249] As an alternative or in addition to NAC, some studies suggest that
garlic, selenium, alpha-lipoic acid, and/or L-cysteine can also boost
cellular levels of Glutathione, although not as effectively. Life
Extension produces a supplement that is comprised of Glutathione,
Cysteine and Vitamin C. Glutathione molecules are large and can have
trouble crossing the intestinal system to reach the blood stream.
However, there are "Glutathione precursers" that are more easily
absorbed. Foods known to be rich in Glutathione include vegetables and
fruits such as spinach, broccoli, brussels sprouts, parsley, avocado,
asparagus, grapefruit, strawberries, milk thistle, whey protein, etc. In
addition, there are "Ultimate Antioxidants" that contain NAC and other
important antioxidants, but do not reach the quality or bioavailability
of these supplements' potential (e.g. Natural Factors.RTM. Ultimate
Antioxidant contains 100 mg unspecified NAC as well as 13 other
ingredients). Milk Thistle, another supplement beneficial to liver
health, functions under different mechanisms. (See Milk Thistle
supplement above for additional information).
[0250] NAC can prove very desirable and/or effective when there is
pulmonary involvement.
[0251] Naltrexone
[0252] Naltrexone hydrochloride is an opioid receptor antagonist that is
prescribed as a treatment to reduce the pleasurable effects of alcohol
and opiod drugs, thereby reducing cravings. It also has implications in
cancer treatment.
[0253] Blockage of Opioid Growth Factor (OGF) and OGFr with the
nonselective opioid receptor antagonist naltrexone has been shown to
upregulate the expression of OGF and OGFr. Administration of a low dosage
of naltrexone (LDN) has been shown to block endogenous opioids from
opioid receptors for a short period of time. The mechanism of action in
cancer targets and inhibits tumor cell proliferation and angiogenesis.
LDN has a stimulatory effect on immune cells via an indirect interaction
with their opiate receptors, whereas high-dose naltrexone has an
inhibitory effect.
[0254] Naltrexone is the active ingredient found in name brands including
Depade, Vivitrol, and ReVia. Naltrexone is most preferably available in
pill form in ReVia (formerly called Trexan). Vivitrol is administered
intramuscularly once a month.
[0255] Approved dosing regimens for naltrexone include:
TABLE-US-00014

Exemplary Approved Dosing Regimens for Naltrexone
Indication Route Dose
Alcohol or Oral 50 mg once a day
Opiate Dependence Optionally 25 mg initial dose
Optionally 100 mg doses

Optionally 150 mg doses every

Imtramulscular 380 mg once a month,
(gluteal injection) alternating buttocks
[0256] It has been demonstrated that low-doses of Naltrexone, given before
bedtime, is associated with clinical improvement and some remissions in
cancer patients, even among patients on no conventional cancer therapies.
Bihari, B., 2009, Low-Dose Naltrexone for Cancer, online publication at:
www.lowdosenaltrexone.org/ldn_and_cancer.htm. A series of published cases
in the journal Integrative Cancer Therapies documented the complete
remissions of 4 patients with advanced pancreatic cancer who combined
intravenous high doses of the antioxidant Alpha-Lipoic Acid along with
daily low-dose oral Naltrexone. Berkson and Berkson, Integr. Cancer
Ther., 5(1):83-9 (2006); Berkson, et al., Integr. Caner Ther. 8(4):416-22
(2009), erratum in Integr. Cancer Ther., 9(2):247 (2010).
[0257] Suitable amounts of Naltrexone for use in accordance with many
embodiments of the present invention will be 0.1-10 mg, preferably 1.0-10
mg, more preferably 1.5-4.5 mg. For the purposes herein, preferred doses
are 3.0 mg and 4.5 mg, in some embodiments rapid release. Related
compounds such as (S)--N-methylnaltrexone and Nalmefene may also be used
in place of Naltrexone, at equivalent Naltrexone dose.
[0258] In some embodiments, inclusion and/or dosing of Naltrexone may be
reduced or excluded, particularly for patients relying on pain
medications with which Naltrexone might or will interfere. Naltrexone can
prove very desirable and/or effective in boosting immune system
responses, but can decrease efficacy of certain pain medications,
sometimes with undesirable effect.
[0259] Opioid Growth Factor
[0260] Opioid Growth Factor (OGF) [Met(5)]-enkephalin is an endogenous
pentapeptide endorphin with antineoplastic and antiangiogenic activities.
OGF acts by binding to the opioid growth factor receptor (OGFr), found on
certain tumor cells and vascular cells, and inhibiting tumor cell
proliferation and angiogenesis. OGF plays a role in cell proliferation
during development, cancer, cellular renewal, wound healing, and
angiogenesis.
[0261] Several signaling pathways are affected by opioids.
Growth-promoting effects were found to be mediated through Akt and Erk
signaling cascades. Death-promoting effects are initiated by inhibition
of nuclear factor-B, increase of Fas expression, p53 stabilization,
cytokine and chemokine release, and activation of nitric oxide synthase,
p38, and c-Jun-N-terminal kinase. These are mediated by opioid receptor
activation and protein-signaling.
[0262] Treatment of tumor cells with OGF slows cell replication in a
dose-related, noncytotoxic way. Opioid Growth Factor [Met(5)]-enkephalin
is tolerated at a maximum dose of 250 .mu.g/kg over a 30-minute
intravenous infusion once or twice weekly. Metronomic dosing of 50
.mu.g/kg injected subcutaneously twice daily shows no toxicity. OGF and
its receptor OGFr are considered a principal endogenous opioid axis for
regulation of cell proliferation.
[0263] Unlike chemotherapy, OGF does not directly destroy cancer cells and
is not cytotoxic. An alternative to opiod growth factor could be
low-dose-naltrexone or other therapies using opiod blocking mechanisms.
[0264] In some embodiments, inclusion and/or dosing of OGH may be reduced
or excluded, particularly for patients relying on pain medications. OGH
can prove very desirable and/or effective in boosting immune system
responses, but can decrease efficacy of certain pain medications,
sometimes with undesirable effect.
[0265] Squalamine
[0266] Squalamine, is an antimicrobial agent, also shown to inhibit the
growth of blood vessels within solid tumors. Squalamine can be derived
from the internal organs of dogfish shark (Squalus acanthias), and has
been produced synthetically as well. Squalamine's common name is
Squalamine lactate. It is also referred to as Aiguillat, Escualamina,
Spiny Dogfish Shark, Squalene, Squalene, Squalus acanthias, Squalamax.TM.
and Evizon. Squalamine should not be confused with shark cartilage, which
is prepared from the cartilage of spiny dogfish sharks, hammerhead sharks
and other shark species.
[0267] Squalamine has been shown to exhibit antiangiogenic properties, and
has been studied as a treatment for cancer, age-related macular
degeneration and bacterial infections. Squalamine enhances bacterial and
fungicidal effects when used in combination with standard antibiotics. In
angiogenic events, Squalamine inhibits multiple growth factors, including
VEGF, PDGF, and bFGF. In addition to its anti-angiogenic mechanism,
Squalamine also inhibits the sodium-proton antiporter pump system in the
cell membrane. By binding to the membrane, it alters the intracellular
pH, disrupts angiogenic signaling, and allows for standard of care
chemotherapeutic agents to enter and induce apoptosis, thereby enhancing
cytotoxicity of such chemotherapeutic drugs. Squalamine has also been
shown to decrease blood flow by decreasing the volume of endothelial
cells in vascular beds and narrowing vessels. Squalamine blocks several
disease pathways including VEGF and MAPK inhibiting angiogenesis,
migration, and proliferation.
[0268] The primary natural source of Squalamine is in the tissue (not oil)
of the liver, gallbladder, spleen, testes, stomach, gills and intestines
of primarily the Dogfish shark, and/or the circulating white blood cells
of the sea lamprey. Alternatively or additionally, Squalamine has been
synthetically engineered. Nu-Gen Nutrition sells Squalamax dietary
supplement which is concentrated squalamine. Squalamine does not have
high oral bioavailability. Squalamine is available in an intravitrial
injectible form, oral supplement, topical eye drops, and nasal spray. The
maximum tolerated dose (MTD) recommended has been found to be 300
mg/m2/day.
[0269] Squalamine can be obtained both naturally at high concentration
through supplements like Squalamax or synthetically through Evizon.
Evizon is the first patented synthetic Squalamine supplement. Squalene
and Shark Cartilage are not substitutes for Squalamine, although both
have been demonstrated to have potential antiviral, antibacterial and
antiangiogenic potential.
[0270] Chemotherapeutic and/or Non-Chemotherapeutic Approved Drugs
[0271] Cyclophosphamide
[0272] Cyclophosphamide (CTX) is a synthetic nitrogen mustard alkylating
agent used to treat cancers and autoimmune disorders. In the liver it is
converted into the active forms, aldophosphamide and phosphoramide
mustard, that have chemotherapeutic activity when they bind to DNA and
inhibit DNA replication and initiate cell death.
[0273] Cyclophosphamide given at the maximum tolerated dose (MTD)
increases cytotoxicity and immunosuppression, and mainly targets
proliferating tumor cells. Alternatively, lower metronomic dose
concentrations administered at regular intervals without rest periods are
immunostimulatory, due to a greater toxicity for suppressor T cells than
helper T lymphocytes, and because of the stimulation of NK cells.
Additionally, metronomic Cyclophosphamide has antiangiogenic properties
by inhibiting preferentially the endothelial cell activity of a tumor's
growing vasculature.
[0274] Administration of metronomic Cyclophosphamide primarily induces
expression of the endogenous inhibitor Thrombospondin-1 (TSP-1). TSP-1
contributes to the suppression of tumor growth when treated with
metronomic Cyclophosphamide Tumors that express a high TSP-1 level are
more susceptible to tumor suppression with this treatment.
[0275] Suppression of the extracellular regulatory kinase 1 and 2 (ERK1/2)
and upstream MEK1/2 proteins is a primary function of Cyclophosphamide.
This mechanism serves to lower levels of expression and phosphorylations
of MEK1/2 and ERK1/2 proteins and inhibit the proliferation of cancer
cells. Cyclophosphamide also activates the PI3K/Akt pathway, a
survival-promoting intracellular signaling pathway.
[0276] Cyclophosphamide is only available by prescription for a metronomic
dosage of 50 mg or less. Trade names include Cytoxan, Neosar, Clafen,
Endoavan, Procytox, Revimmune, Carlovan, Cicloval, Cycloblastin,
Cyclobastine, CYCLO-cell, Cyclostin, Cyclostine, Cytophophan, Endoxana,
Enduxan, Fosfaseron, Genoxal, Ledoxine, Procytox, and Sendoxan. The
chemical structure of Cyclophosphamide is also known as cytophosphane,
ciclofosfamida, ciclofosfamide, claphene, cp monohydrate, CPM,
cyclophspham, Cyclophosphamid monohydrate, cyclophosphamidum,
cyclophosphan, cyclophosphanum, mitoxan, syklofosfamid, zytoxan.

[0278] In many embodiments of the present invention, Cyclophosphamide is
administered according to a metronomic dosing regimen. In certain
particular embodiments, such metronomic dosing regimen is or includes
doses of 50 mg/day.
[0279] Other Agents
[0280] Those skilled in the art will appreciate that various of the agents
discussed above herein in the section entitled "Nutraceutical and/or
Non-Chemotherapeutic Agents" could alternatively or additionally be
addressed in the present section treating "Chemotherapeutic and/or
Non-Chemotherapeutic Approved Drugs". It will specifically be appreciated
that such characterizations are intended for convenience and not
limitation.
[0281] In particular, those skilled in the art will specifically
appreciate that above-discussed agents such as Metformin and/or
Naltrexone can reasonably be considered in either the category of
nutraceutical compounds or the category of approved drugs.
Monitoring and/or Adjusting Therapy
[0282] Components of inventive therapeutic protocols may, in some
embodiments, be prescribed on a predetermined individualized program
based, for example, on the blood profile of an individual who has been
diagnosed with a cancer. After an initial period, such blood test(s) may
be repeated and adjustment made to the regimen, both as to the component
compounds and their dosing regimens (e.g., timing and/or amount). In some
embodiments, inventive combination regimens are specifically blended to
address the specific deficiencies detected in the patient's blood and are
precisely dosed accordingly based on, for example, the patient's weight,
age, sex, and/or severity of the imbalances or deficiencies intended to
be addressed by the nutraceutical. One skilled in the art, for example a
patient's oncologist or primary care physician, following analysis of,
for instance, blood samples from the affected patient, will be able to
determine the precise combination of nutraceuticals and the proper
dosages of each compound.
Administration
[0283] In general, agents included in inventive combination therapies may
be administered in any form, preferably as a tablet, powder, or liquid,
formulated into a pharmaceutically acceptable carrier or excipient,
depending on the condition of the patient. In some embodiments, providing
custom tailored dosages eliminates the need for pre-formulated capsules
and tablets. Additionally, non-active ingredients well known in the art,
such as binders, fillers, coatings, preservatives, coloring agents,
flavoring agents and other additives may optionally be formulated with
one or more administered agents, or left out completely if there is a
risk of negative side effects to the patient such as increased the risk
of intestinal inflammation or interference with the absorption of
particular compounds.
[0284] In some embodiments, one or more agents included in an inventive
therapeutic regimen is administered according to a metronomic regimen.
[0285] In some embodiments, inventive therapeutic regimens are added to a
program of chemotherapy. In some such embodimnets, the compositions of
the invention supplement the chemotherapeutic action by addressing
additional processes and pathways not addressed by chemotherapeutics and
on which the cancer cells of the patient could rely for energy, unchecked
proliferation, and migration if such processes and pathways were not
controlled or normalized. In many embodiments, effectiveness of any
suitable chemotherapeutic used for the treatment of cancer, more
particularly for the treatment of epithelial cell related cancers cancer
will be improved by adding compositions and combination therapies
according to the invention.

the present invention are particularly useful in the treatment of
leiomyosarcoma.
EXEMPLIFICATION
Example 1: Exemplary Seven-Component Regimen
[0295] A particularly preferred supplementary regimen useful, for example,
for treatment of cancers of epithelial origin in cancer patients,
includes the following combination of agents:
TABLE-US-00016
TABLE 13
Exemplary Inventive Therapeutic Protocol
Agent Daily Dose
Cyclophosphamide 50 mg
Curcumin 2400 mg (6 .times. 400 mg)
Melatonin 10 mg
Naltrexone 4.5 mg
Metformin 500 mg
Alpha Lipoic Acid 1200 mg (4 .times. 300 mg)
Genistein (pure) 8400 mg (6 .times. 1400 mg)
[0296] While this combination was specifically designed with reference to
actual cancer patients and background data, it was realized that the
approach of addressing critical pathways and processes, particularly
angiogenesis and other metabolic and signaling pathways, that are
dysregulated in cancer but may be returned toward normal state by the
administration of nutraceutical, chemotherapeutic and/or
non-chemotherapeutic combinations, leading to anti-oncogenic effects.
This realization has been applied to design a large range of combination
therapies that will be effective so long as they address at least a three
abnormally activated or dysregulated pathways from among
angiogenesis/vasculogenesis, tumor suppression dysregulation, cell cycle
arrest (apoptosis disruption and cell proliferation), and metabolic
disruption (e.g., Warburg effect, anaerobic glycolysis, oxidative
stress). The compositions and method of the present invention are
designed to combine a range of agents and/or therapeutic modalities that
address at least three endogenous processes (see, for example, as
illustrated in FIG. 1).
Example 2: Exemplary Inventive Therapeutic Regimen Including Three
Non-Chemotherapeutic Drugs
[0297] The present Example specifically describes compositions for use in
accordance with the present invention that utilize three
non-chemotherapeutic drugs. These three in combination, i.e., Metformin,
Cyclophosphamide, and Naltrexone, provide a novel composition, in some
embodiments particularly useful for treatment of pancreatic cancer. Such
composition addresses critical processes in cancer development and thus
provides a useful composition for the therapeutic approach to treatment
taught herein.
[0298] The use of these three drugs in combination for cancer treatment,
especially as an adjunct to chemotherapy, is a novel combination
providing effects on several of the most important metabolic,
intercellular signaling, and intracellular signaling pathways that are
dysregulated in cancers of epithelial origin and other cancers. These
include, notably, the pro-angiogenic processes, tumor suppression, and
Warburg effect/anaerobic glycolysis/oxidative stress. Accordingly,
compositions comprising Metformin, cyclophosphamide, and Naltrexone, are
a particularly promising embodiment of the present invention.
Example 3: Exemplary Tailored Inventive Therapeutic Regimens
[0299] The present Example describes certain particular embodiments of
inventive compositions and/or therapeutic regimens.
[0300] In particular, the following Tables 1-6 provide a list of
nutraceutical compounds and/or non-chemotherapeutic or chemotherapy drugs
for use in methods and compositions of the present invention, for example
for the treatment of cancers of epithelial origin. Each Table lists
compounds useful for particular categories of cancer-affected metabolic
pathways, intercellular signaling pathways, or intracellular signaling
pathways, and thus a composition of the invention will typically be
comprised of a combination of compounds selected from at least the first
four tables (Tables 1-4).
[0301] In certain embodiments, by conducting a careful analysis of, for
example, a blood sample from a patient suffering from pancreatic cancer,
a compound or compounds will be chosen from each Table (depending on the
results of the blood test) to create a
nutraceutical/non-chemotherapeutic/chemotherapeutic drug "cocktail" to
administer to the patient. By following the teachings disclosed herein,
one skilled in the art, for example a patient's oncologist or primary
care physician, will be able to choose the most beneficial combination of
compounds as well as the optimal dosage of each. As some compounds are
listed in more than one Table herein, it will be understood by one
skilled in the art that if, for example, curcumin is chosen from Table 2,
it will not be chosen from any other table in which it is listed for
preparation of a composition according to the present invention.

Example 4: Exemplary Inventive Four-Component Therapeutic Regimen
[0303] The present Example describes a particular four-component
composition for use in accordance with the present invention.
[0304] Although many variations are of course possible based on the
disclosure provided herein, a proposed embodiment of the present
invention for use with a chemotherapy treatment regimen for cancer, more
particularly for the treatment of epithelial cell related cancers cancer
would include:
[0305] 1) CYCLOPHOSPHAMIDE--50 mg/day
[0306] 2) METFORMIN--500 mg/day;
[0307] 3) NALTREXONE--4.5 mg at bedtime;
[0308] 4) MELATONIN--10 mg/day.
[0309] To the foregoing ingredients, one or more nutraceutical compounds
may be added for particular effects, in accordance with the present
disclosure.
Example 5: Designing Therapeutic Regimens
[0310] As described in Example 1, and throughout the present disclosure,
the present invention recognizes that a variety of prescription drugs
and/or traditional or nutraceutical agents have been developed that can
target any of the 4 key hallmark cancer pathways described herein. In
accordance with the present invention, well tolerated such agents (e.g.,
that show a high therapeutic index) are particularly useful for inclusion
in combination cancer therapies. Particular consideration is given to
agents that, when combined, can and/or do show synergistic interaction
within the framework of the pathways discussed herein.
[0311] Moreover, in accordance with the present invention, selection of
agents for inclusion in inventive therapeutic strategies does not rely
solely on prevention data, or data demonstrating decreased risk of
developing cancer (since, as discussed herein, the mechanisms involved in
cancer development do not necessarily overlap with therapeutically
relevant mechanisms important in metastatic tumors).
[0312] Still further, in some embodiments, in vitro data generated with
non-physiological or therapeutically irrelevant drug concentrations is
discounted or ignored in designing inventive combination regimens, unless
backed up by efficacy or mechanism-based data generated in in vivo tumor
models or clinical trials.
[0313] The particular therapy set forth in Example 1 is representative of
this approach and has the particular benefits that it:
[0314] Targets four key cancer pathways, simultaneously, that are most
relevant for invasive and metastatic cancer. Each pathway is targeted
with at least three separate approaches using at least three different
compounds (Table 15). Each compound has extensive in vitro, in vivo and,
for several, clinical profiles that scientifically support potential for
intervention in the targeted pathways. Additionally, each is currently
being tested in phase II or III clinical trials in oncology. The design
is intended to provide therapeutic synergy in each pathway and across
pathways to significantly extend progression-free and overall survival;
and.
[0315] Utilizes non-toxic doses of each compound, which can be
administered orally and chronically, to create a high quality of life
during long term therapy. Existing preclinical safety data and extensive
clinical experience with all of the compounds suggests the combination
will be well-tolerated during chronic treatment of advanced malignancies.

[0316] By using orally bioavailable and non-toxic compounds simultaneously
targeting four key pathways required for survival and growth of tumors,
this therapeutic regimen has the potential to significantly extend
progression-free and overall survival with a high quality of life.
Example 6: Treatment of Patient with Adenocarcinoma, Lung Primary
[0317] The present Example describes treatment of a female patient, age
67, diagnosed with adenocarcinoma, lung primary.
[0318] Patient initially presented with severe shortness of breath and
difficulty breathing. Nasal spray, cough medicines, antibiotics, and
steroids were prescribed for persistent cough, but improvement was not
observed. After several weeks of such therapy, patient was admitted to
the emergency room (ER) for continued shortness of breath. X-ray and CT
scans were performed, and nodules on lungs were detected. Subsequent
bronchoscopy and PET scan confirmed presence of cancer in lungs, liver,
and bones of lower back. Palpable nodules were also felt on exam, in the
neck/shoulder area.
[0319] Beginning 1 week after diagnosis, patient was treated with
traditional chemotherapy with 5FU, oxiliplatinum, and leucovorin.
Specifically, the patient received two, two-day rounds of:
TABLE-US-00023
Agent Daily Dose
5FU 3240 mg
Oxaliplatinum 115 mg
Leucovorin 540 mg
Rounds were administered two weeks apart. Patient also used oxygen daily.
CT and PET scans were utilized as diagnostic measurements.
[0320] Beginning less than two weeks after diagnosis (i.e., between the
two rounds of traditional chemotherapy), patient began receiving the
following inventive therapeutic protocol:
TABLE-US-00024
Exemplary Inventive Therapeutic Protocol
Agent Daily Dose
Cyclophosphamide 50 mg
Curcumin 1200 mg (6 .times. 400 mg)
Melatonin 10 mg
Naltrexone 4.5 mg, as tolerated
Alpha Lipoic Acid 1200 mg (4 .times. 300 mg)
Genistein (pure) 8400 mg (6 .times. 1400 mg)
Patient also received protein powder to increase caloric intake, as well
as vitamin D3 and n-acetylcysteine (NAC). Oxygen was also continued.
[0321] After two weeks on this inventive therapeutic protocol, the
patient's CT scan after inventive therapy and before second round of
chemotherapy showed 50% reduction in lung mets. The patient continued to
experience breathing difficulty, however.
[0322] Treatment with this inventive therapeutic protocol was terminated
after less than one month, when the patient was admitted to the hospital
due to extreme difficulty breathing and spitting up mucus with blood.
Patient was intubated and placed on a ventilator. Patient was treated
with broad-spectrum antibiotics, anti-viral drugs, and morphine. Patient
was determined to have infection with cytomegalovirus (CMV). Bronchial
fluid cytology shows presence of cancer. Fever persisted. Oxygen
saturation was unstable. Patient passed away shortly thereafter.
Example 7: Treatment of Patient with Breast Leiomyosarcoma (LMS)
[0323] The present Example describes treatment of a female patient, age
64, diagnosed with breast leiomyosarcoma (LMS), which had previously been
mis-diagnosed as benign intraductal papilloma, and then as poorly
differentiated sarcoma. The patient resides in a community without access
to a sarcoma specialty center or sarcoma surgery.
[0324] Prior to initiation of inventive therapy, the patient had undergone
a variety of therapeutic procedures, in each case followed by a relapse.
For example, she had a breast quadrantectomy, followed by a radical
mastectomy and preventative lymph node removal, but relapsed in just a
couple of weeks. Tumor was reported to have grown from 1.5 cm to 4 cm in
three weeks. She then had surgery to remove the tumor, scar tissue and
pectoraliz muscle, followed by 2 months of 32 additional sessions of
radiotherapy when second relapse detected. After 6 weeks she underwent
her third tumor resection along with adjacent rib and muscle tissue. Bone
marrow contained malignant cancer cells. She took approximately one
month-long break before initiating inventive therapy.
[0325] Patient has received the following inventive therapy protocol:
TABLE-US-00025
TABLE 16
Exemplary Inventive Therapeutic Protocol
Agent Daily Dose
Cyclophosphamide 50 mg
Curcumin 2400 mg (6 .times. 400 mg)
Melatonin 10 mg
Naltrexone 4.5 mg
Metformin 500 mg
Alpha Lipoic Acid 1200 mg (4 .times. 300 mg)
Genistein (pure) 8400 mg (6 .times. 1400 mg)
[0326] Patient has also regularly been taking Omega3, Nutrilite Daily
multivitamin, concentrated ganoderma mushroom and other plant extracts
including dandelion, petiveria, and yellow poui (tabebuia). The patient
also takes prescription drugs on a daily basis including Metoprolol,
Losartan, Hydrochlorothiazide and Amlodipine to treat hypertension and
Levothyroxine which is a thyroid hormone. The patient maintains a
no-sugar diet.
[0327] Once patient was on inventive therapy, tumor growth apparently
slowed significantly. Relapse was detected after 145 days, at which point
the detected tumor was said to be 3.8 cm.times.4 cm.times.5 cm, a similar
size to the one that had grown in three weeks on prior therapy.
[0328] The patient reports that inventive therapy is well tolerated and
has a very positive impact on overall state of health and feeling of
well-being despite presence of active disease.
Example 8: Treatment of Patient with Ovarian Cancer of Unidentified Origin
[0329] The present Example describes treatment of a female patient, age
63, initially diagnosed 6 years before initiation of inventive therapy,
with stage IIIC Ovarian Cancer.
[0330] Since initial diagnosis, patient underwent therapeutic procedures
including: a complete hysterectomy to remove a large ovarian tumor with
colon resection; ureteral stent; intra-abdominal port; chest port;
removal of a major bowel obstruction together with six feet of small
intestine and one foot of colon; treatment of infected wound sites;
removal of the gallbladder; pericardial window thoracotomy; and multiple
other surgeries to deal with complications. Patient also required regular
use of supplemental oxygen. Still further, patient received nine rounds
of chemotherapy (Intraperitoneal chemotherapy, Carbopaltin, Taxol,
Gemzar, Lipidox, Taxotere, Avastin, Cytoxin, Doxil, Navelbine), and one
cyberknife radiation treatment.
[0331] After almost six years of such conventional treatment, the patient
was given a life expectancy estimate from her oncologist: 2-4 weeks to
live. Patient was discharged from the hospital to hospice care.
[0332] Patient was presented for consideration for receipt of inventive
therapy. At the time, patient suffered from significant fluid in lungs
which was regularly drained every 2-3 days. Shortness of breath continued
to require supplemental oxygen. Patient had little appetite, had been
consistently losing weight, had been feeling very weak, and was confined
to bed most of the day. Patient's CA-125 had been rising steadily for
more than three months, almost quadrupling (rising from 559 to 2901)
between tests run about 3.5 months prior to initiation of therapy and
about 3 weeks post-initiation of therapy. By eight weeks post-initiation
of therapy, this trend had reversed; CA-125 was measured at 833.
[0333] Patient received the following inventive therapy:
TABLE-US-00026
TABLE 17
Exemplary Inventive Therapeutic Protocol
Agent Daily Dose
Cyclophosphamide 50 mg
Curcumin Occasional low doses
(given bowel damage,
absorption of curcumin
was a particular challenge
for this patient)
Melatonin 10 mg
Naltrexone Occasional 2.25 mg doses
(patient was on pain meds
and naltrexone, though
useful to boost the
immune system, can
decrease effectiveness of
some such meds, so half
doses were utilized, and
only occasionally)
Metformin 500 mg
Alpha Lipoic Acid 1200 mg (4 .times. 300 mg)
Genistein (pure) 8400 mg (6 .times. 1400 mg)
[0334] During the first three weeks on the inventive therapeutic protocol,
the patient continued to lose weight (98 to 85 lbs). Protein powders were
used to try to increase caloric intake. During this period, patient also
took dichloroacetate (DCA), resveratrol, vitamin D3, L-glutamine,
magnesium oil, and pain/anti-nausea medications as needed, including
Zofran, Vicodin, Oxytocin, Delaudid, and Ativan.
[0335] After 3 weeks on the inventive therapeutic protocol, the patient's
use of supplemental oxygen was significantly reduced, her abdominal
distension resolved, her appetite increased, and her weight began to
increase toward 92 pounds. As noted above, after about 8 weeks on the
inventive therapeutic protofol, CA-125 had dropped to 833. The patient's
husband reported that despite some nausea and back pain caused by the
lung drains, the patient also had increased appetite and increased
energy.
[0336] The patient stopped taking the inventive therapy after three
months. Two weeks later, her CA-125 measured 3432. She passed away three
weeks after that measurement.
[0337] Although the patient ultimately terminated the therapy and then
lost her battle with cancer, she had lived approximately 16-18 weeks
longer than her oncologist and hospice nurse predicted.
Example 9: Treatment of Patient with Advanced Stage IV Leiomyosarcoma
Including Multiple Metastases
[0338] The present Example describes use of an inventive therapeutic
protocol in the treatment of a female patient, age 46, diagnosed with
retroperitenial leiomyosarcoma with metastases to lungs, liver and spine.
[0339] At the time of presentation, patient had only 1 kidney working at
78% because a tumor is pressing against her other kidney's ureter.
Patient had not received any chemotherapy, surgery or radiation prior to
initiation of inventive therapy. In fact, given location of tumors and
extent of disease, patient was not considered to be a candidate for
surgery.
[0340] Beginning 4 months after diagnosis the patient received the
following inventive therapeutic protocol:
TABLE-US-00027
TABLE 18
Exemplary Inventive Therapeutic Protocol
Agent Daily Dose
Cyclophosphamide 50 mg
Curcumin 2400 mg (6 .times. 400 mg)
Melatonin 10 mg
Naltrexone 4.5 mg
Metformin 500 mg
Alpha Lipoic Acid 1200 mg (4 .times. 300 mg)
Genistein (pure) 8400 mg (6 .times. 1400 mg)
[0341] In addition, the patient regularly took Vitamin D3, Beta Glucanase,
Organic Coffee Enema, DHA, DCA, Digestase, Peptidase enzymes,
serratiopeptidase enzymes, Hemicaellulase enzymes, Glucoamylase enzymes,
Apha Galactosidase enzymes, liver-ND, milk thistle, Thiamin, Riboflavin,
Vitamin B6 and B12, Folate, Biotin, Pantothenic Acid, PABA, Inositol,
Modified Citrus Pectin, elderberry fruit, fermented soy, magnolia bark,
red clover, mistletoe, moringa oliefera, and medicinal mushrooms
including reishi mushrooms, chaga mushrooms, coriolus mushrooms, maitake
mushrooms and cordyceps mushrooms. Also, the patient took various
prescription drugs as needed, including: Dilaudid, Dolophine and
Hydrocodone for pain, Dexamethasone for inflammation, Klonopin for
anxiety and Remeron for sleep.
[0342] While receiving inventive therapy, the patient maintained a diet
with no gluten, no meat, no dairy, and no sugar; she consumed only whole
foods and juices as much as possible.
[0343] For the first 2-3 weeks of inventive therapy, patient continued to
feel significant pain, particularly in the spine, as would be expected
for dying tumors. After seven weeks on inventive therapy, spine pain was
significantly reduced; some pain remained, though diminished, on the
right side, under the rib case, where significant disease is known to
exist.
[0344] Patient has reported more energy, better appetite, and brighter
outlook notwithstanding terminal prognosis delivered by oncologist.
Patient specifically reports that overall feeling and outlook while on
inventive therapy changed from a feeling of decline and despair to one of
quality of life and strong desire to live. Within the seventh week on
inventive therapy, the patient reported that she has not felt this well
since before her diagnosis.
Example 10: Treatment of Patient with Retroperitoneal Leiomyosarcoma
[0345] The present Example describes use of an inventive therapeutic
protocol in the treatment of a female patient, age 65, who had initially
been incorrectly diagnosed with "hematoma of the right psoas" (later
determined to be a tumor bleed). A year later, the patient was again
misdiagnosed, this time with Meckel's diverticulitis or a cyst.
Eventually, patient was correctly diagnosed after surgery. Correct
diagnosis was stage 2b Retroperitoneal Leiomyosarcoma (LMS). LMS cells
were given a grade 3 diagnosis (high-grade) indicating fast growing and
highly likely to spread. Mitotic Index measured 23. The patient had an
LMS tumor, measuring 3.5 cm.times.3 cm.times.3 cm, that was wrapped
around the patient's ureter, was fibrosed to her appendix, her inferior
vena cava, and the psoas muscle.
[0346] Once properly diagnosed with LMS, patient had been treated with,
for example, laparoscopic resection of the primary lesion; 2 cycles
chemotherapy (doxorubicin/dacarbazine); chemoembolization of liver
lesions; RFA (Radio Frequency Ablation) for the liver and cryoablation.
Additionally, since diagnosis, interval scans have confirmed the
following conditions: small nodules in the lungs and abdomen; "multiple"
new pulmonary nodules detected bilaterally in lungs; additional
metastases in the upper area of the back, posterior chest wall, and the
right psoas.
[0347] Patient's cancer continued to develop, and within three years had
progressed to Stage IV metastatic disease with lesions to the liver and
lungs. By the time patient was referred for receipt of inventive therapy,
more than 4 years after diagnosis, it was clear that her disease was
getting more aggressive--four new distinct areas of metastasis
approaching centimeter magnitudes had been identified.
[0348] Patient received the following inventive therapy:
TABLE-US-00028
TABLE 19
Exemplary Inventive Therapeutic Protocol
Agent Daily Dose
Cyclophosphamide 50 mg
Curcumin 2400 mg (6 .times. 400 mg)
Melatonin 10 mg
Naltrexone 4.5 mg
Metformin 500 mg
Alpha Lipoic Acid 1200 mg (4 .times. 300 mg)
Genistein (pure) 8400 mg (6 .times. 1400 mg)
In addition, at various times while receiving inventive therapy, the
patient has received Lorazepam, Alprazolam, Effexo, Valacyclovier,
Beta1,3D Glucan, Yamoa, Cinnamon, and/or Zometa (monthly infusions for
bone strengthening).
[0349] Within days on the inventive therapy, the patient reported a
feeling of well being. Energy and sleep patterns dramatically improved.
Two weeks after beginning the inventive therapy the patient could palpate
a bump in the right shoulder which had been identified as one of the new
areas of metastasis detected in March. Ultimately, it was excised and
determined to be LMS.
[0350] By 6 months on inventive therapy, scans indicated that not a single
nodule on the chest CT was greater than 1.7 cm in width and no new
nodules were detected. The "something" previously detected at the right
psoas had remained unchanged since beginning the inventive therapy and
there have been no new hepatic lesions.
[0351] By 8 months on the NED Therapy the patient's multiple pulmonary
nodules and hepatic lesions still remained unchanged in size.
[0352] After nine months on the inventive protocol, the patient was
diagnosed as diabetic. At the same time, MRI imaging revealed a
marrow-filling lesion in the right humerus and widely disseminated
disease throughout the musculature and skeleton. The size and nature of
the right humerus lesion with crenulated edges is indicative of old
disease, as per general consensus of the patient's sarcoma expert, local
oncologist, and attending radiologist.
[0353] A comparison of CT scans pre- and post-inventive therapy, suggests
that no new metastases have developed in the imaged areas since beginning
the inventive therapy and the patient's known lesions have been stable.
The patient's sarcoma expert has advised that she continue on her
"current regimen" (NED Therapy) for her "indolent" disease.
[0354] Patient has reported no adverse side effects while on inventive
therapy. The patient indicates she has high energy, feels twenty years
younger than her age, and describes quality of life as "excellent".
