TECHNICAL FIELD
[0001] The present application relates to methods, compositions, and kits for the treatment
of pancreatic cancer by administering compositions comprising nanoparticles comprising
a taxane (such as paclitaxel) and a carrier protein in combination with gemcitabine.
BACKGROUND
[0002] Pancreatic cancer has one of the highest mortality rates among all cancers and is
expected to cause an estimated 37,390 deaths in the United States in 2012. See American
Cancer Society,
Cancer Facts and Figures 2012. For all stages of pancreatic cancer combined, the 1-and 5-year relative survival
rates are 26% and 6%, respectively; this high mortality rate from pancreatic cancer
is, at least in part, due to the high incidence of metastatic disease at the time
of diagnosis. See
id. As a result, treatment options for pancreatic cancer are very limited.
[0003] The standard first-line treatment for treating pancreatic cancer is gemcitabine (e.g.,
GEMZAR®), which was approved by the Food and Drug Administration ("FDA") in 1996.
In a clinical study with 126 patients with locally advanced pancreatic cancer (63
treated with gemcitabine), gemcitabine was shown to be superior to 5-fluororuracil
(5-FU) in terms of median overall survival (5.7 months for gemcitabine versus 4.2
months for 5-FU), median time to disease progression (2.1 months for gemcitabine versus
0.9 months for 5-FU), and clinical benefit responses. However, although gemcitabine
has become a standard palliative therapy for treating pancreatic cancer since its
approval in 1996, there has been little improvement in pancreatic cancer treatment.
[0004] The gemcitabine/erlotinib combination improved the median overall survival (6.4 months
versus 6.0 months) and median progression free survival (3.8 months versus 3.5 months)
over gemcitabine monotherapy. See
Moore et al., J. Clin. Oncol. 25:1960-1966 (2007). Based on this very modest improvement in overall survival and progression free
survival (0.4 and 0.3 months, respectively), the FDA approved the gemcitabine/erlotinib
combination in 2005. Despite its approval, the gemcitabine/erlotinib combination has
not been widely used as a standard of care for treating pancreatic cancer because
of side effects associated with the gemcitabine/erlotinib combination and the minimal
improvement on survival over gemcitabine monotherapy. See
Nieto et al., The Oncologist, 13:562-576 (2008).
[0005] Albumin-based nanoparticle compositions have been developed as a drug delivery system
for delivering substantially water insoluble drugs such as a taxanes.
See, for example,
U.S. Pat. Nos. 5,916,596;
6,506,405;
6,749,868, and
6,537,579,
7,820,788, and
7,923,536. Abraxane®, an albumin stabilized nanoparticle formulation of paclitaxel, was approved
in the United States in 2005 and subsequently in various other countries for treating
metastatic breast cancer. It was recently approved for treating non-small cell lung
cancer in the United States, and has also shown therapeutic efficacy in various clinical
trials for treating difficult-to-treat cancers such as pancreatic cancer and melanoma.
Albumin derived from human blood has been used for the manufacture of Abraxane® as
well as various other albumin-based nanoparticle compositions.
[0006] Albumin bound paclitaxel (e.g., Abraxane®) in combination with gemcitabine was found
to be well tolerated in advanced pancreatic cancer in a Phase I/II study and showed
evidence of antitumor activity. See, for example,

DETAILED DESCRIPTION
[0041] The present invention provides a composition comprising nanoparticles comprising
paclitaxel and an albumin for use in a method of treating metastatic or locally advanced
pancreatic cancer in an individual in need thereof, wherein the composition comprising
nanoparticles comprising paclitaxel and an albumin is to be administered with gemcitabine,
and wherein the individual is selected for treatment based on (i) having pancreatic
cancer in the primary location in the head of the pancreas, and/or (ii) having serum
CA19-9 level that is ≥ 59 x ULN (Upper Limit of Normal).
[0042] The present invention also provides in combination:
- (a) a composition comprising nanoparticles comprising paclitaxel and an albumin; and
- (b) gemcitabine,
for use in a method of treating metastatic or locally advanced pancreatic cancer in
an individual in need thereof, wherein the individual is selected for treatment based
on (i) having pancreatic cancer in the primary location in the head of the pancreas,
and/or (ii) having serum CA19-9 level that is ≥ 59 x ULN (Upper Limit of Normal).
[0043] The present invention also provides a kit comprising (a) an effective amount of a
composition comprising nanoparticles comprising paclitaxel and an albumin; and (b)
an effective amount of gemcitabine, and (c) an instruction for using the nanoparticle
composition and gemcitabine for treating metastatic or locally advanced pancreatic
cancer in a human individual, wherein the individual is selected for treatment based
on (i) having pancreatic cancer in the primary location in the head of the pancreas,
and/or (ii) having serum CA19-9 level that is ≥ 59 x ULN (Upper Limit of Normal).
[0044] Disclosed herein are methods for treatment of pancreatic cancer in an individual
using a composition comprising nanoparticles comprising a taxane (such as paclitaxel)
and a carrier protein in combination with gemcitabine.
[0045] A phase III study using an albumin stabilized nanoparticle formulation of paclitaxel
(
Nab-paclitaxel, or Abraxane®) in combination with gemcitabine versus gemcitabine alone
was conducted in patients with metastatic adenocarcinoma of the pancreas. Gemcitabine
(e.g., GEMZAR®) is the standard first-line treatment for treating pancreatic cancer.
The study showed that the median survival in the intent-to-treat analysis was 8.5
months in the Abraxane®/gemcitabine arm compared with 6.7 months in the gemcitabine
arm. The progression-free survival (PFS) in the Abraxane®/gemcitabine arm was 5.5
months compared to the PFS of 3.7 months in the gemcitabine arm, showing a significant
improvement. The study also showed that the 9- and 12-month PFS rates were doubled
in the Abraxane®/gemcitabine arm and that the overall response rate by independent
radiological review was tripled from 7% in the gemcitabine arm to 23% in the Abraxane®/gemcitabine
arm. The results of this study were statistically and clinically persuasive, robust,
consistent across subgroups, and supported by multiple endpoints. Moreover, the combination
is especially effective in pancreatic cancer patients having a poor prognosis, for
example but not limited to, patients having a late stage (e.g., stage IV) pancreatic
cancer, patients having 3 or more (such as more than 3) metastatic sites, patients
having metastasis in the liver, patients having metastasis in the lung, patients having
a serum CA 19-9 level of ≥59 x ULN (upper limit of normal), patients having a poor
performance status (such as patients having a Karnofsky performance status (KPS) score
of <90, for example 70-80), and/or patients wherein the primary location of the pancreatic
cancer is the head of the pancreas.
[0046] Also disclosed are methods, compositions, and kits for treatment of pancreatic cancer
in various individuals by administration of a composition comprising nanoparticles
comprising a taxane (such as paclitaxel) and a carrier protein in combination with
gemcitabine.

[0074] Any individual having pancreatic cancer (e.g., metastatic pancreatic cancer) may
be treated using a method described herein. In some embodiments, the individual is
chemotherapy-naive or has not been treated with chemotherapy. In some embodiments,
the individual has not been previously treated for the pancreatic cancer. In some
embodiments, the individual has not been previously treated for the metastatic pancreatic
cancer (such as metastatic adenocarcinoma of the pancreas). In some embodiments, the
individual has not received prior therapy or prior chemotherapy (such as prior cytotoxic
chemotherapy) for the pancreatic cancer (e.g., the metastatic pancreatic cancer).
In some embodiments, the individual has not received radiotherapy or surgery for the
pancreatic cancer (e.g., the metastatic pancreatic cancer). In some embodiments, the
individual has not received prior adjuvant therapy (e.g., adjuvant cytotoxic chemotherapy).
In some embodiments, the individual has previously been treated with 5-FU as a radiation
sensitizer in the adjuvant setting (e.g., at least about 6 months prior to the start
of the treatment method). In some embodiments, the individual has previously been
treated with gemcitabine as a radiation sensitizer in the adjuvant setting (e.g.,
at least about 6 months prior to the start of the treatment method).
[0075] The methods described herein may be practiced in an adjuvant setting. Adjuvant setting
may refer to a clinical setting in which an individual has had a history of a cancer
described herein, and generally (but not necessarily) been responsive to therapy,
which includes, but is not limited to, surgery (e.g., surgery resection), radiotherapy,
and chemotherapy; however, because of their history of cancer, these individuals are
considered at risk of development of the disease. Treatment or administration in the
adjuvant setting refers to a subsequent mode of treatment. The degree of risk (e.g.,
when an individual in the adjuvant setting is considered as "high risk" or "low risk")
depends upon several factors, most usually the extent of disease when first treated.
[0076] In some embodiments, the method is practiced in a neoadjuvant setting, i.e., the
method may be carried out before the primary/definitive therapy. In some embodiments,
the method is used to treat an individual who has previously been treated. Any of
the methods of treatment described herein may be used to treat an individual who has
not previously been treated.
[0077] Methods described herein may be used to treat an individual having pancreatic cancer
who has previously been treated for the pancreatic cancer. The prior treatment may
include a chemotherapy agent such as gemcitabine (e.g., GEMZAR). In some embodiments,
the prior treatment comprises gemcitabine and/or erlotinib. In some embodiments, the
prior treatment comprises 5-FU. In some embodiments, the individual has been previously
treated for the pancreatic cancer and the individual is substantially refractory to
the prior treatment. In some embodiments, the individual has been previously treated
for the pancreatic cancer and is no longer or only partially responsive to the prior
treatment. In some embodiments, the individual is initially responsive to the prior
treatment but has progressed on the prior treatment. In some embodiments, the individual
is not responsive to the prior treatment.
[0078] Methods described herein may be used as a first line therapy. For example, in some
embodiments, the method is for treating metastatic, locally advanced unresectable,
or stage IV pancreatic cancer in an individual comprising administering to the individual
(i) an effective amount of a composition comprising nanoparticles comprising paclitaxel
coated with an albumin (including nanoparticles having an average diameter of no greater
than about 200 nm); and (ii) an effective amount of gemcitabine, wherein the treatment
is first line treatment. In some embodiments, the method is for treating metastatic,
locally advanced unresectable, or stage IV pancreatic cancer in a human individual
comprising administering to the individual (i) an effective amount of
Nab-paclitaxel (for example about 5 mg/ml
Nab-paclitaxel); and (ii) an effective amount of gemcitabine, wherein the treatment is
first line treatment.
[0079] Methods described herein may also be used as a second line or third line therapy
after the prior treatment for pancreatic cancer has failed or has substantially failed,
or the pancreatic cancer is substantially refractory to the first line therapy. In
some embodiments, the individual has received at least one line of therapy (e.g.,
chemotherapy or immunotherapy) for treating pancreatic cancer (e.g., metastatic pancreatic
cancer) prior to receiving the treatment described herein. In some embodiments, the
patient has received 1 line of therapy or 2 lines of therapy (e.g., 1 line of chemotherapy
or immunotherapy or 2 lines of chemotherapy or immunotherapy). Thus, the treatment
described herein may be used as a second line therapy or a third line therapy. The
prior line of therapy described herein may be a prior line of chemotherapy or immunotherapy.
The first line of therapy may comprise any of the following: gemcitabine, 5-FU, and/or
erlotinib.

[0180] In some embodiments, the individual is selected for treatment based on hENT1 levels.
The methods in some embodiments comprise determining the level of hENT1 (Human Equilibrative
Nucleoside Transporter 1) in an individual. In some embodiments, the level is the
activity level of hENT1 in a sample, and the activity level can encompass, for example,
a measure of the total amount of hydrophilic nucleosides that are moved across the
membrane by hENT1 in a cell, a sample, or a tumor. In some embodiments the level is
an expression level that correlates to the activity level. In some embodiments the
level is a measure of a hENT1 protein present in a cell (for example the surface of
a cell), a sample, or a tumor. In some aspects the level is a measure of a nucleic
acid present in a cell, a sample, or a tumor. In some embodiments, the level is based
on a mutation or polymorphism in the hENT1 gene that correlates with the protein or
mRNA level of hENT1. In some embodiments, the level is the protein expression level.
In some embodiments, the level is the mRNA level.
[0181] The levels of nucleoside transporters such as hENT1 can be determined by methods
known in the art. See, for example,
Spratlin et al., Cancers 2010, 2, 2044-2054;
Santini et al., Current Cancer Drug Targets, 2011, 11, 123-129;

polymorphonuclear cells, macrophages, and erythrocytes.
[0183] In some embodiments, the sample is a tumor tissue, normal tissue adjacent to said
tumor, normal tissue distal to said tumor, blood sample, or other biological sample.
In some embodiments, the sample is a fixed sample. Fixed samples include, but are
not limited to, a formalin fixed sample, a paraffin-embedded sample, or a frozen sample.
In some embodiments, the sample is a biopsy containing cancer cells. In a further
embodiment, the biopsy is a fine needle aspiration of pancreatic cancer cells. In
a further embodiment, the biopsy is laparoscopy obtained pancreatic cancer cells.
In some embodiments, the biopsied cells are centrifuged into a pellet, fixed, and
embedded in paraffin. In some embodiments, the biopsied cells are flash frozen. In
some embodiments, the biopsied cells are mixed with an antibody that recognizes hENT1.
In some embodiments, a biopsy is taken to determine whether an individual has cancer
and is then used as a sample. In some embodiments, the sample comprises surgically
obtained tumor cells. In some embodiments, samples may be obtained at different times
than when the determining of hENT1 levels occurs.
[0184] In some embodiments, the sample comprises a circulating metastatic pancreatic cancer
cell. In some embodiments, the sample is obtained by sorting pancreatic circulating
tumor cells (CTCs) from blood. In a further embodiment, the CTCs have detached from
a primary tumor and circulate in a bodily fluid. In yet a further embodiment, the
CTCs have detached from a primary tumor and circulate in the bloodstream. In a further
embodiment, the CTCs are an indication of metastasis.
[0185] In some embodiments, the protein expression level of hENT1 is determined. In some
embodiments, the mRNA level of the hENT1 is determined. In some embodiments, the level
of hENT1 is determined by an immunohistochemistry method.
[0186] The level of hENT1 may be a high level or a low level as compared to a control sample.
In some embodiments, the level of hENT1 in an individual is compared to the level
of hENT1 in a control sample. In some embodiments the level of hENT1 in a subject
is compared to the level of hENT1 in multiple control samples. In some embodiments,
multiple control samples are used to generate a statistic that is used to classify
the level of hENTlin an individual with cancer.
[0187] In some embodiments, the DNA copy number is determined, and a high DNA copy number
for the gene encoding hENT1 (for example a high DNA copy number as compared to a control
sample) is indicative of a high level of hENT1.
[0188] The classification or ranking of hENT1 level (i.e., high or low) may be determined
relative to a statistical distribution of control levels. In some embodiments, the
classification or ranking is relative to a control sample obtained from the individual.
In some embodiment the levels of hENT1 is classified or ranked relative to a statistical
distribution of control levels. In some embodiments, the level of hENT1 is classified
or ranked relative to the level from a control sample obtained from the subject.
[0189] Control samples can be obtained using the same sources and methods as non-control
samples. In some embodiments, the control sample is obtained from a different individual
(for example an individual not having cancer and/or an individual sharing similar
ethnic, age, and gender identity). In some embodiments when the sample is a tumor
tissue sample, the control sample may be a non-cancerous sample from the same individual.
In some embodiments, multiple control samples (for example from different individuals)
are used to determine a range of levels of hENT1 in a particular tissue, organ, or
cell population. In some embodiments, the control sample is a cultured tissue or cell
that has been determined to be a proper control. In some embodiments, the control
is a cell that does not express hENT1. In some embodiments, a clinically accepted
normal level in a standardized test is used as a control level for determining hENT1
level. In some embodiments, the reference level of hENT1 in the subject is classified
as high, medium or low according to a scoring system, such as an immunohistochemistry-based
scoring system, for example an H-Score as further discussed herein. In some embodiments,
the reference level of hENT1 in the subject is classified as a low sample when the
H-Score is less than or equal to the overall median H-Score.
[0190] In some embodiments, the hENT1 level is determined by measuring the level hENT1 in
an individual and comparing to a control or reference (e.g., the median level for
the given patient population or level of a second individual). For example, if the
level of hENT1 for the single individual is determined to be above the median level
of the patient population, that individual is determined to have high expression of
hENT1. Alternatively, if the level of hENT1 for the single individual is determined
to be below the median level of the patient population, that individual is determined
to have low expression of the hENT1. In some embodiments, the individual is compared
to a second individual and/or a patient population which is responsive to treatment.
In some embodiments, the individual is compared to a second individual and/or a patient
population which is not responsive to treatment. In any of the embodiments herein,
the levels are determined by measuring the level of a nucleic acid encoding hENT1.
For example, if the level of an mRNA encoding hENT1 for the single individual is determined
to be above the median level of the patient population, that individual is determined
to have a high level of an mRNA encoding hENT1. Alternatively, if the level of mRNA
encoding hENT1 for the single individual is determined to be below the median level
of the patient population, that individual is determined to have a low level of an
mRNA encoding hENT1.
[0191] In some embodiments, the reference level of hENT1 is determined by obtaining a statistical
distribution of hENT1 levels.
[0192] In some embodiments, hENT1 mRNA level is determined, and a low level is an mRNA level
less than about 1.1, 1.2, 1.3, 1.5, 1.7, 2, 2.2, 2.5, 2.7, 3, 5, 7, 10, 20, 50, 70,
100, 200, 500, 1000 times or less than 1000 times to that of what is considered as
clinically normal or to the level obtained from a control. In some embodiments, high
level is an mRNA level more than about 1.1, 1.2, 1.3, 1.5, 1.7, 2, 2.2, 2.5, 2.7,
3, 5, 7, 10, 20, 50, 70, 100, 200, 500, 1000 times or more than 1000 times to that
of what is considered as clinically normal or to the level obtained from a control.
[0193] In some embodiments, hENT1 protein expression level is determined, for example by
immunohistochemistry. For example, the criteria for low or high levels can be made
based on the number of positive staining cells and/or the intensity of the staining,
for example by using an antibody that specifically recognizes the hENT1 protein. In
some embodiments, the hENT1 level is low if less than about 1%, 5%, 10%, 15%, 20%,
25%, 30%, 35%, 40%, 45%, or 50% cells have positive staining. In some embodiments,
the hENT1 level is low if the staining is 1%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%,
45%, or 50% less intense than a positive control staining.
[0194] In some embodiments, the hENT1 level is high if more than about 40%, 45%, 50%, 55%,
60%, 65%, 70%, 75%, 80%, 85%, or 90%, cells have positive staining. In some embodiments,
the hENT1 level is high if the staining is as intense as positive control staining.
In some embodiments, the hENT1 level is high if the staining is 80%, 85%, or 90% as
intense as positive control staining.
[0195] In some embodiments, the scoring is based on an "H-score" as described in
US Pat. Pub. No. 2013/0005678. An H-score is obtained by the formula: 3xpercentage of strongly staining cells+2xpercentage
of moderately staining cells+percentage of weakly staining cells, giving a range of
0 to 300.
[0196] In some embodiments, strong staining, moderate staining, and weak staining are calibrated
levels of staining, wherein a range is established and the intensity of staining is
binned within the range. In some embodiments, strong staining is staining above the
75th percentile of the intensity range, moderate staining is staining from the 25th
to the 75th percentile of the intensity range, and low staining is staining is staining
below the 25th percentile of the intensity range. In some aspects one skilled in the
art, and familiar with a particular staining technique, adjusts the bin size and defines
the staining categories.
[0197] In some embodiments, the label high hENT1 staining is assigned where greater than
50% of the cells stained exhibited strong reactivity, the label no hENT1 staining
is assigned where no staining was observed in less than 50% of the cells stained,
and the label low hENT1 staining is assigned for all of other cases.
[0198] In some embodiments, the assessment and scoring of the hENT1 level in a sample, patient,
etc., is performed by one or more experienced clinicians, i.e., those who are experienced
with hENT1 expression and hENT1 staining patterns. For example, in some embodiments,
the clinician(s) is blinded to clinical characteristics and outcome for the samples,
patients, etc. being assessed and scored.

Modes of Administration
[0204] The dose of the taxane (such as paclitaxel) nanoparticle compositions and/or the
dose of gemcitabine administered to an individual (such as a human) according to (or
as applied to) a method described herein may vary with the particular composition,
the mode of administration, and the type of pancreatic cancer described herein being
treated. The dose of the taxane (such as paclitaxel) nanoparticle compositions and/or
the dose of gemcitabine administered to an individual (such as a human) may also be
adjusted (such as reduced) based on an individual's symptoms (such as adverse reactions).
In some embodiments, the dose or amount is effective to result in a response. In some
embodiments, the dose or amount is effective to result in an objective response (such
as a partial response or a complete response). In some embodiments, the dose of paclitaxel

is below the level that induces a toxicological effect (i.e., an effect above a clinically
acceptable level of toxicity) or is at a level where a potential side effect can be
controlled or tolerated when the composition (and/or gemcitabine) is administered
to the individual.
[0208] In some embodiments, the amount of the composition (and/or gemcitabine) is close

[0224] The administration of gemcitabine can be extended over an extended period of time,
such as from about a month up to about seven years. In some embodiments, gemcitabine
is administered over a period of at least about any of 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 18, 24, 30, 36, 48, 60, 72, or 84 months.
[0225] The composition comprising nanoparticles comprising a taxane (such as paclitaxel)
(also referred to as "nanoparticle composition") and gemcitabine can be administered
simultaneously (i.e., simultaneous administration) and/or sequentially (i.e., sequential
administration).
[0226] In some embodiments, the nanoparticle composition and gemcitabine are administered
simultaneously. The term "simultaneous administration," as used herein, means that
the nanoparticle composition and the other agent are administered with a time separation
of no more than about 15 minute(s), such as no more than about any of 10, 5, or 1
minutes. When the drugs are administered simultaneously, the drug in the nanoparticles
and the other agent may be contained in the same composition (e.g., a composition
comprising both the nanoparticles and the other agent) or in separate compositions
(e.g., the nanoparticles are contained in one composition and the other agent is contained
in another composition).
[0227] In some embodiments, the nanoparticle composition and gemcitabine are administered
sequentially. The term "sequential administration" as used herein means that the drug
in the nanoparticle composition and the other agent are administered with a time separation
of more than about 15 minutes, such as more than about any of 20, 30, 40, 50, 60 or
more minutes. Either the nanoparticle composition or gemcitabine may be administered
first. In some embodiments, gemcitabine is administered immediately after the completion
of the administration of the nanoparticle composition. The nanoparticle composition
and gemcitabine are contained in separate compositions, which may be contained in
the same or different packages.
[0228] In some embodiments, the administration of the nanoparticle composition and gemcitabine
are concurrent, i.e., the administration period of the nanoparticle composition and
that of gemcitabine overlap with each other. In some embodiments, the nanoparticle
composition is administered for at least one cycle (for example, at least any of 2,
3, or 4 cycles) prior to the administration of gemcitabine. In some embodiments, gemcitabine
is administered for at least any of one, two, three, or four weeks. In some embodiments,
the administrations of the nanoparticle composition and gemcitabine are initiated
at about the same time (for example, within any one of 1, 2, 3, 4, 5, 6, or 7 days).
In some embodiments, the administrations of the nanoparticle composition and gemcitabine
are terminated at about the same time (for example, within any one of 1, 2, 3, 4,
5, 6, or 7 days). In some embodiments, the administration of gemcitabine continues
(for example for about any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 months)
after the termination of the administration of the nanoparticle composition. In some
embodiments, the administration of gemcitabine is initiated after (for example after
about any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 months) the initiation of
the administration of the nanoparticle composition. In some embodiments, the administrations
of the nanoparticle composition and gemcitabine are initiated and terminated at about
the same time. In some embodiments, the administrations of the nanoparticle composition
and gemcitabine are initiated at about the same time and the administration of gemcitabine
continues (for example for about any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or
12 months) after the termination of the administration of the nanoparticle composition.
In some embodiments, the administration of the nanoparticle composition and gemcitabine
stop at about the same time and the administration of gemcitabine is initiated after
(for example after about any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 months)
the initiation of the administration of the nanoparticle composition.
[0229] In some embodiments, the method comprises more than one treatment cycle, wherein
at least one of the treatment cycles comprises the administration of (i) an effective
amount of a composition comprising nanoparticles comprising paclitaxel and an albumin;
and (ii) an effective amount of gemcitabine. In some embodiments, the treatment cycle
comprises no less than about (such as about) 21 days (e.g., 4 weeks). In some embodiments,
the treatment cycle comprises less than about 21 days (for example weekly or daily).
In some embodiments, the treatment cycle comprises about 28 days.
[0230] In some embodiments, the administration of the nanoparticle composition and gemcitabine
are non-concurrent. For example, in some embodiments, the administration of the nanoparticle
composition is terminated before gemcitabine is administered. In some embodiments,
the administration of gemcitabine is terminated before the nanoparticle composition
is administered. The time period between these two non-concurrent administrations
can range from about two to eight weeks, such as about four weeks.
[0231] The dosing frequency of the drug-containing nanoparticle composition and gemcitabine
may be adjusted over the course of the treatment, based on the judgment of the administering
physician. When administered separately, the drug-containing nanoparticle composition
and gemcitabine can be administered at different dosing frequency or intervals. For
example, the drug-containing nanoparticle composition can be administered weekly,
while gemcitabine can be administered more or less frequently. In some embodiments,
sustained continuous release formulation of the drug-containing nanoparticle and/or
gemcitabine may be used. Various formulations and devices for achieving sustained
release are known in the art. Exemplary dosing frequencies are further described herein.
[0232] The nanoparticle composition and gemcitabine can be administered using the same route
of administration or different routes of administration. Exemplary administration
routes are further described herein. In some embodiments (for both simultaneous and
sequential administrations), paclitaxel in the nanoparticle composition and gemcitabine
are administered at a predetermined ratio. For example, in some embodiments, the ratio
by weight of paclitaxel in the nanoparticle composition and gemcitabine is about 1
to 1. In some embodiments, the weight ratio may be between about 0.001 to about 1
and about 1000 to about 1, or between about 0.01 to about 1 and 100 to about 1. In
some embodiments, the ratio by weight of paclitaxel in the nanoparticle composition
and gemcitabine is less than about any of 100:1, 50:1, 30:1, 10:1, 9:1, 8:1, 7:1,
6:1, 5:1, 4:1, 3:1, 2:1, and 1:1 In some embodiments, the ratio by weight of the taxane
(such as paclitaxel) in the nanoparticle composition and gemcitabine is more than
about any of 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 30:1, 50:1, 100:1. Other
ratios are contemplated.
[0233] The doses required for the taxane (such as paclitaxel) and/or gemcitabine may be
lower than what is normally required when each agent is administered alone. Thus,
in some embodiments, a subtherapeutic amount of paclitaxel in the nanoparticle composition
and/or gemcitabine are administered. "Subtherapeutic amount" or "subtherapeutic level"
refer to an amount that is less than therapeutic amount, that is, less than the amount
normally used when the drug in the nanoparticle composition and/or gemcitabine are
administered alone. The reduction may be reflected in terms of the amount administered
at a given administration and/or the amount administered over a given period of time
(reduced frequency).
[0234] In some embodiments, enough gemcitabine is administered so as to allow reduction
of the normal dose of the drug in the nanoparticle composition required to effect
the same degree of treatment by at least about any of 5%, 10%, 20%, 30%, 50%, 60%,
70%, 80%, 90%, or more. In some embodiments, enough paclitaxel in the nanoparticle
composition is administered so as to allow reduction of the normal dose of gemcitabine
required to effect the same degree of treatment by at least about any of 5%, 10%,
20%, 30%, 50%, 60%, 70%, 80%, 90%, or more.
[0235] In some embodiments, the dose of both paclitaxel in the nanoparticle composition
and gemcitabine are reduced as compared to the corresponding normal dose of each when
administered alone. In some embodiments, both paclitaxel in the nanoparticle composition
and gemcitabine are administered at a subtherapeutic, i.e., reduced, level. In some
embodiments, the dose of the nanoparticle composition and/or gemcitabine is substantially
less than the established maximum toxic dose (MTD). For example, the dose of the nanoparticle
composition and/or gemcitabine is less than about 50%, 40%, 30%, 20%, or 10% of the
MTD.
[0236] In some embodiments, the dose of paclitaxel and/or the dose of gemcitabine is higher
than what is normally required when each agent is administered alone. For example,
in some embodiments, the dose of the nanoparticle composition and/or gemcitabine is
substantially higher than the established maximum toxic dose (MTD). For example, the
dose of the nanoparticle composition and/or gemcitabine is more than about 50%, 40%,
30%, 20%, or 10% of the MTD of the agent when administered alone.
[0237] As will be understood by those of ordinary skill in the art, the appropriate doses
of gemcitabine will be approximately those already employed in clinical therapies
wherein the gemcitabine is administered alone or in combination with other agents.
Variation in dosage will likely occur depending on the condition being treated. As
described above, in some embodiments, gemcitabine may be administered at a reduced
level.
[0238] The nanoparticle compositions and/or gemcitabine can be administered to an individual
(such as human) via various routes, including, for example, parenteral, intravenous,
intraventricular, intra-arterial, intraperitoneal, intrapulmonary, oral, inhalation,
intravesicular, intramuscular, intra-tracheal, subcutaneous, intraocular, intrathecal,
transmucosal, and transdermal. In some embodiments, sustained continuous release formulation
of the composition and/or gemcitabine may be used. In some embodiments, the composition
(and/or gemcitabine) is administered intravenously. In some embodiments, the composition
(and/or gemcitabine) is administered intraportally. In some embodiments, the composition
(and/or gemcitabine) is administered intraarterially. In some embodiments, the composition
(and/or gemcitabine) is administered intraperitoneally. In some embodiments, the composition
(and/or gemcitabine) is administered intrathecally. In some embodiments, the composition
(and/or gemcitabine) is administered through a ported catheter to spinal fluid. In
some embodiments, the composition (and/or gemcitabine) is administered intraventricularly.
In some embodiments, the composition (and/or gemcitabine) is administered systemically.
In some embodiments, the composition (and/or gemcitabine) is administered by infusion.
In some embodiments, the composition (and/or gemcitabine) is administered by infusion
through implanted pump. In some embodiments, the composition (and/or gemcitabine)
is administered by a ventricular catheter. In some embodiments, the composition (and/or
gemcitabine) is administered through a port or portacath. In some embodiments, the
port or portacath is inserted into a vein (such as jugular vein, subclavian vein,
or superior vena cava).
[0239] In some embodiments, the method is for treating pancreatic cancer (e.g., metastatic
pancreatic adenocarcinoma) in an individual comprising administering to the individual
(i) an effective amount of a composition comprising nanoparticles comprising paclitaxel
and an albumin; and (ii) an effective amount of gemcitabine, wherein the dose of paclitaxel
in the nanoparticle composition is between about 50 mg/m

2 (including for example about 100 mg/m
2 to about 300 mg/m
2, about 100 mg/m
2 to about 200 mg/m
2, or about 100 mg/m
2 to about 150 mg/m
2, or about 100 mg/m
2, or about 125 mg/m
2, or about 150 mg/m
2) and the dose of gemcitabine is about 500 mg/m
2 to about 2000 mg/m
2 (for example, about 750 mg/m
2 to about 1500 mg/m

2 to about 1200 mg/m
2, about 750 mg/m
2, about 1000 mg/m

weeks of four weeks or weekly. In some embodiments, gemcitabine is administered weekly
for three weeks of four weeks or weekly.

(or less than about) any of 900, 800, 700, 600, 500, 400, 300, 200, and 100 nm. In

90%, 95%, or 99%) of the nanoparticles in the composition have a diameter of no greater
than about 200 nm, including for example no greater than about any one of 190, 180,

at least about 50% (for example at least any one of 60%, 70%, 80%, 90%, 95%, or 99%)
of the nanoparticles in the composition fall within the range of about 20 to about
400 nm, including for example about 20 to about 200 nm, about 40 to about 200 nm,
about 30 to about 180 nm, and any one of about 40 to about 150, about 50 to about
120, and about 60 to about 100 nm.
[0244] In some embodiments, the albumin has sulfhydryl groups that can form disulfide bonds.
In some embodiments, at least about 5% (including for example at least about any one
of 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, or 90%) of an albumin in the
nanoparticle portion of the composition are crosslinked (for example crosslinked through
one or more disulfide bonds).
[0245] In some embodiments, the nanoparticles comprising paclitaxel are coated with a carrier
protein (e.g., an albumin such as human albumin or human serum albumin). In some embodiments,
the composition comprises paclitaxel in both nanoparticle and non-nanoparticle forms
(e.g., in the form of paclitaxel solutions or in the form of soluble carrier protein/nanoparticle
complexes), wherein at least about any one of 50%, 60%, 70%, 80%, 90%, 95%, or 99%
of paclitaxel in the composition are in nanoparticle form. In some embodiments, paclitaxel
in the nanoparticles constitutes more than about any one of 50%, 60%, 70%, 80%, 90%,
95%, or 99% of the nanoparticles by weight. In some embodiments, the nanoparticles
have a non-polymeric matrix. In some embodiments, the nanoparticles comprise a core
of paclitaxel that is substantially free of polymeric materials (such as polymeric
matrix).
[0246] In some embodiments, the composition comprises an albumin in both nanoparticle and
non-nanoparticle portions of the composition, wherein at least about any one of 50%,
60%, 70%, 80%, 90%, 95%, or 99% of the carrier protein in the composition are in non-nanoparticle
portion of the composition.
[0247] In some embodiments, the weight ratio of an albumin (such as human albumin or human
serum albumin) and paclitaxel in the nanoparticle composition is about 18:1 or less,
such as about 15:1 or less, for example about 10:1 or less. In some embodiments, the

[0248] In some embodiments, the nanoparticle composition comprises one or more of the above
characteristics.
[0249] The nanoparticles described herein may be present in a dry formulation (such as lyophilized
composition) or suspended in a biocompatible medium. Suitable biocompatible media
include, but are not limited to, water, buffered aqueous media, saline, buffered saline,
optionally buffered solutions of amino acids, optionally buffered solutions of proteins,
optionally buffered solutions of sugars, optionally buffered solutions of vitamins,
optionally buffered solutions of synthetic polymers, lipid-containing emulsions, and
the like.
[0250] In some embodiments, the pharmaceutically acceptable carrier comprises an albumin
such as human albumin or human serum albumin. Examples of suitable carrier proteins
include proteins normally found in blood or plasma, which include, but are not limited
to, immunoglobulin including IgA, lipoproteins, apolipoprotein B, α-acid glycoprotein,
β-2-macroglobulin, thyroglobulin, transferrin, fibronectin, factor VII, factor VIII,
factor IX, factor X, and the like. In some examples, the carrier protein is non-blood
protein, such as casein, α-lactalbumin, β-lactoglobulin. The proteins may either be
natural in origin or synthetically prepared. In the context of the invention the carrier
protein is an albumin, such as human albumin or human serum albumin. In some embodiments,
the albumin is a recombinant albumin.
[0251] Human serum albumin (HSA) is a highly soluble globular protein of M
r 65K and consists of 585 amino acids. HSA is the most abundant protein in the plasma
and accounts for 70-80 % of the colloid osmotic pressure of human plasma. The amino
acid sequence of HSA contains a total of 17 disulfide bridges, one free thiol (Cys
34), and a single tryptophan (Trp 214). Intravenous use of HSA solution has been indicated
for the prevention and treatment of hypovolumic shock (see, e.g.,
Tullis, JAMA, 237: 355-360, 460-463, (1977)) and
Houser et al., Surgery, Gynecology and Obstetrics, 150: 811-816 (1980)) and in conjunction with exchange transfusion in the treatment of neonatal hyperbilirubinemia
(see, e.g.,
Finlayson, Seminars in Thrombosis and Hemostasis, 6, 85-120, (1980)). Other albumins are contemplated, such as bovine serum albumin. Use of such non-human
albumins could be appropriate, for example, in the context of use of these compositions
in non-human mammals, such as the veterinary (including domestic pets and agricultural
context). Human serum albumin (HSA) has multiple hydrophobic binding sites (a total
of eight for fatty acids, an endogenous ligand of HSA) and binds a diverse set of
taxanes, especially neutral and negatively charged hydrophobic compounds (
Goodman et al., The Pharmacological Basis of Therapeutics, 9th ed, McGraw-Hill New
York (1996)). Two high affinity binding sites have been proposed in subdomains IIA and IIIA
of HSA, which are highly elongated hydrophobic pockets with charged lysine and arginine
residues near the surface which function as attachment points for polar ligand features
(see, e.g.,
Fehske et al., Biochem. Pharmcol., 30, 687-92 (198a),
Vorum, Dan. Med. Bull., 46, 379-99 (1999),
Kragh-Hansen, Dan. Med. Bull., 1441, 131-40 (1990),
Curry et al., Nat. Struct. Biol., 5, 827-35 (1998),
Sugio et al., Protein. Eng., 12, 439-46 (1999),
He et al., Nature, 358, 209-15 (199b), and
Carter et al., Adv. Protein. Chem., 45, 153-203 (1994)). Paclitaxel and propofol have been shown to bind HSA (see, e.g.,
Paal et al., Eur. J. Biochem., 268(7), 2187-91 (200a),
Purcell et al., Biochim. Biophys. Acta, 1478(a), 61-8 (2000),
Altmayer et al., Arzneimittelforschung, 45, 1053-6 (1995), and
Garrido et al., Rev. Esp. Anestestiol. Reanim., 41, 308-12 (1994)). In addition, docetaxel has been shown to bind to human plasma proteins (see, e.g.,
Urien et al., Invest. New Drugs, 14(b), 147-51 (1996)).
[0252] The carrier protein (e.g., an albumin such as human albumin or human serum albumin)
in the composition generally serves as a carrier for the taxane, i.e., the albumin
in the composition makes the taxane (such as paclitaxel) more readily suspendable
in an aqueous medium or helps maintain the suspension as compared to compositions
not comprising a carrier protein. This can avoid the use of toxic solvents (or surfactants)
for solubilizing the taxane, and thereby can reduce one or more side effects of administration
of the taxane (such as paclitaxel) into an individual (such as a human). Thus, in
some embodiments, the composition described herein is substantially free (such as
free) of surfactants, such as Cremophor (or polyoxyethylated castor oil) (including
Cremophor EL® (BASF)). In some embodiments, the nanoparticle composition is substantially
free (such as free) of surfactants. A composition is "substantially free of Cremophor"
or "substantially free of surfactant" if the amount of Cremophor or surfactant in
the composition is not sufficient to cause one or more side effect(s) in an individual
when the nanoparticle composition is administered to the individual. In some embodiments,
the nanoparticle composition contains less than about any one of 20%, 15%, 10%, 7.5%,
5%, 2.5%, or 1% organic solvent or surfactant. In some embodiments, the albumin is
human albumin or human serum albumin. In some embodiments, the albumin is recombinant
albumin.
[0253] The amount of a carrier protein such as an albumin in the composition described herein
will vary depending on other components in the composition. In some embodiments, the
composition comprises an albumin in an amount that is sufficient to stabilize paclitaxel
in an aqueous suspension, for example, in the form of a stable colloidal suspension
(such as a stable suspension of nanoparticles). In some embodiments, an albumin is
in an amount that reduces the sedimentation rate of paclitaxel in an aqueous medium.
For particle-containing compositions, the amount of an albumin also depends on the
size and density of nanoparticles of paclitaxel.
[0254] A taxane (such as paclitaxel) is "stabilized" in an aqueous suspension if it remains
suspended in an aqueous medium (such as without visible precipitation or sedimentation)
for an extended period of time, such as for at least about any of 0.1, 0.2, 0.25,
0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 36, 48, 60, or 72 hours. The suspension
is generally, but not necessarily, suitable for administration to an individual (such
as human). Stability of the suspension is generally (but not necessarily) evaluated
at a storage temperature (such as room temperature (such as 20-25 °C) or refrigerated
conditions (such as 4 °C)). For example, a suspension is stable at a storage temperature
if it exhibits no flocculation or particle agglomeration visible to the naked eye
or when viewed under the optical microscope at 1000 times, at about fifteen minutes
after preparation of the suspension. Stability can also be evaluated under accelerated
testing conditions, such as at a temperature that is higher than about 40 °C.
[0255] In some embodiments, an albumin is present in an amount that is sufficient to stabilize
paclitaxel in an aqueous suspension at a certain concentration. For example, the concentration
of paclitaxel in the composition is about 0.1 to about 100 mg/ml, including for example
any of about 0.1 to about 50 mg/ml, about 0.1 to about 20 mg/ml, about 1 to about
10 mg/ml, about 2 mg/ml to about 8 mg/ml, about 4 to about 6 mg/ml, or about 5 mg/ml.
In some embodiments, the concentration of paclitaxel is at least about any of 1.3
mg/ml, 1.5 mg/ml, 2 mg/ml, 3 mg/ml, 4 mg/ml, 5 mg/ml, 6 mg/ml, 7 mg/ml, 8 mg/ml, 9
mg/ml, 10 mg/ml, 15 mg/ml, 20 mg/ml, 25 mg/ml, 30 mg/ml, 40 mg/ml, and 50 mg/ml. In
some embodiments, an albumin is present in an amount that avoids use of surfactants
(such as Cremophor), so that the composition is free or substantially free of surfactant
(such as Cremophor).
[0256] In some embodiments, the composition, in liquid form, comprises from about 0.1% to
about 50% (w/v) (e.g. about 0.5% (w/v), about 5% (w/v), about 10% (w/v), about 15%
(w/v), about 20% (w/v), about 30% (w/v), about 40% (w/v), or about 50% (w/v)) of an
albumin. In some embodiments, the composition, in liquid form, comprises about 0.5%
to about 5% (w/v) of an albumin.
[0257] In some embodiments, the weight ratio of an albumin to paclitaxel in the nanoparticle
composition is such that a sufficient amount of taxane binds to, or is transported
by, the cell. While the weight ratio of a carrier protein (e.g., an albumin) to taxane
will have to be optimized for different carrier protein (e.g., an albumin) and taxane
combinations, generally the weight ratio of carrier protein (e.g., an albumin), to
taxane (such as paclitaxel) (w/w) is about 0.01:1 to about 100:1, about 0.02:1 to
about 50:1, about 0.05:1 to about 20:1, about 0.1:1 to about 20:1, about 1:1 to about
18:1, about 2:1 to about 15:1, about 3:1 to about 12:1, about 4:1 to about 10:1, about
5:1 to about 9:1, or about 9:1. In some embodiments, an albumin to paclitaxel weight
ratio is about any of 18:1 or less, 15:1 or less, 14:1 or less, 13:1 or less, 12:1
or less, 11:1 or less, 10:1 or less, 9:1 or less, 8:1 or less, 7:1 or less, 6:1 or
less, 5:1 or less, 4:1 or less, and 3:1 or less. In some embodiments, the weight ratio
of the albumin (such as human albumin or human serum albumin) to paclitaxel in the
composition is any one of the following: about 1:1 to about 18:1, about 1:1 to about
15:1, about 1:1 to about 12:1, about 1:1 to about 10:1, about 1:1 to about 9:1, about
1:1 to about 8:1, about 1:1 to about 7:1, about 1:1 to about 6:1, about 1:1 to about
5:1, about 1:1 to about 4:1, about 1:1 to about 3:1, about 1:1 to about 2:1, about
1:1 to about 1:1.
[0258] In some embodiments, an albumin allows the composition to be administered to an individual
(such as human) without significant side effects. In some embodiments, an albumin
such as human serum albumin or human albumin is in an amount that is effective to
reduce one or more side effects of administration of paclitaxel to a human. The term
"reducing one or more side effects of administration of the taxane (such as paclitaxel)"
refers to reduction, alleviation, elimination, or avoidance of one or more undesirable
effects caused by the taxane, as well as side effects caused by delivery vehicles
(such as solvents that render the taxanes suitable for injection) used to deliver
the taxane. Such side effects include, for example, myelosuppression, neurotoxicity,
hypersensitivity, inflammation, venous irritation, phlebitis, pain, skin irritation,
peripheral neuropathy, neutropenic fever, anaphylactic reaction, venous thrombosis,
extravasation, and combinations thereof. These side effects, however, are merely exemplary
and other side effects, or combination of side effects, associated with taxanes (such
as paclitaxel) can be reduced.

paclitaxel and an albumin (such as human albumin or human serum albumin), wherein
the nanoparticles have an average diameter of no greater than about 200 nm. In some

for example about 2 mg/ml to about 8 mg/ml, or about 5 mg/ml.
[0266] Methods of making nanoparticle compositions are known in the art. For example, nanoparticles
containing taxanes (such as paclitaxel) and carrier protein (e.g., an albumin such
as human serum albumin or human albumin) can be prepared under conditions of high
shear forces (e.g., sonication, high pressure homogenization, or the like). These
methods are disclosed in, for example,
U.S. Pat. Nos. 5,916,596;
6,506,405;
6,749,868,
6,537,579 and

U.S. Pat. Pub. Nos. 2007/0082838,
2006/0263434 and
PCT Application WO08/137148.
[0267] Briefly, the taxane (such as paclitaxel) is dissolved in an organic solvent, and
the solution can be added to a carrier protein solution such as an albumin solution.
The mixture is subjected to high pressure homogenization. The organic solvent can
then be removed by evaporation. The dispersion obtained can be further lyophilized.
Suitable organic solvent include, for example, ketones, esters, ethers, chlorinated
solvents, and other solvents known in the art. For example, the organic solvent can
be methylene chloride or chloroform/ethanol (for example with a ratio of 1:9, 1:8,
1:7, 1:6, 1:5, 1:4, 1:3, 1:2, 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, or 9:1).

EXAMPLES
Example 1. A randomized phase 3 study of weekly Nab-paclitaxel plus gemcitabine versus
gemcitabine Alone in Patients with Metastatic Adenocarcinoma of the Pancreas (MPACT)
[0308] The MPACT study was an open-label, randomized, international, multicenter, Phase
3 study designed to compare
Nab-paclitaxel plus gemcitabine administered weekly to standard treatment (gemcitabine
monotherapy) with respect to overall survival (OS), progression-free survival (PFS),
and tumor response in patients diagnosed with metastatic adenocarcinoma of the pancreas.
[0309] Patients were assigned to one of two treatment arms, which were: (1)
Nab-paclitaxel (125 mg/m
2) as a 30-minute intravenous (IV) infusion, followed by gemcitabine (1000 mg/m
2) as a 30-minute IV infusion with Cycle 1 consisting of an 8-week cycle with
Nab-paclitaxel plus gemcitabine administered on Days 1, 8, 15, 29, 36, and 43, and Cycle
2 onwards consisting of 4-week cycles with weekly administration for 3 weeks (on Days
1, 8, and 15) followed by a week of rest; or (2) gemcitabine (1000 mg/m
2) as a 30-minute IV infusion with Cycle 1 consisting of an 8-week cycle with gemcitabine
administered on Days 1, 8, 15, 22, 29, 36, and 43, and Cycle 2 onwards consisting
of 4-week cycles with weekly administration for 3 weeks (on Days 1, 8, and 15) followed
by a week of rest. Treatment was continued until the patient experienced disease progression
(based on investigator's assessment) or unacceptable toxicity, required palliative
radiotherapy, withdrew consent, or the patient's physician felt it was no longer in
the best interest of the patient to continue on treatment. Patients who had not experienced
disease progression were followed with regularly scheduled spiral CT/MRI scans every
8 weeks in both arms. Patients were followed for survival until death or study closure.
[0310] The 1:1 randomization was stratified by: (1) Karnofsky performance status (PS) (70-80
versus 90-100); (2) Region (Australia, North America, Eastern/Western Europe); (3)
Presence of liver metastasis (Yes vs. No).
[0311] The primary efficacy endpoint was overall survival (OS). Secondary efficacy endpoints
were progression-free survival (PFS) (measured by blinded, independent radiology assessments
done at 8 weeks), objective tumor response according to Response Evaluation Criteria
in Solid Tumors (RECIST v. 1.0) based on Spiral computed tomography (CT) scans/magnetic
resonance imaging (MRI). Other endpoints included were progression-free survival and
objective response rate (ORR) by investigator review, disease control rate (DCR),
time to failure (TTF), and safety/tolerability by National Cancer Institute Common
Terminology Criteria for Adverse Events v. 3.0 (NCI CTCAE).
[0312] The sample size was increased prior to the interim analysis to increase the power
from 80% to 90% (842 patients, 608 events) to detect a hazard ratio (HR) of 0.769
(2-sided α: 0.049). 1 interim survival analysis was planned for futility. The intent-to-treat
(ITT) population was evaluated for efficacy, the treated population for safety. Treatment
differences in overall survival and progression-free survival were tested using stratified
log-rank; objective response rates were tested using the chi-squared test.
[0313] Study endpoints were determined by analyzing the following criteria: (1) changes
in serum CA 19-9 levels; (2) changes in plasma SPARC (secreted protein, acidic and
rich in cysteine) levels; (3) time and duration of response (using RECIST v. 1.0);
(4) disease control rate based on objective response or stable disease ≥ 16 weeks;
(5) time to treatment failure; (6) progression-free survival and overall response
rate by investigator; and (7) tumor response by PET scans using EORTC criteria and
blinded radiology assessments. When assessing study endpoints, researchers examined
correlations between objective tumor response as determined by CT and PET scans, molecular
marker expression and efficacy, and objective tumor response as determined by PET,
progression-free survival, CA 19-9 levels, SPARC levels and overall survival.
[0314] Each patient had to meet the following study inclusion criteria: (1) definitive histologically
or cytologically confirmed metastatic pancreatic adenocarcinoma (definitive diagnosis
was made by integrating the histopathological data within the context of the clinical

and no lingering toxicities were present; patients that received cytotoxic doses of
gemcitabine or any other chemotherapy in the adjuvant setting were excluded); (6)

or more consecutive days during the course of the study.
[0316] The MPACT study enrolled 861 patients (431 in the
Nab-paclitaxel plus gemcitabine arm, 430 in the gemcitabine arm) with metastatic pancreatic
cancer in the United States (N=476), Canada (N=63), Australia (N=120), Western Europe
(N=76), and Eastern Europe (N=126).
[0317] Figure 1 shows the MPACT study design, and Tables 4 and 5 provide patient demographics

[0318] The treatment arms were well balanced with respect to demographics and known prognostic
features, such as age, performance status, percent of patients with liver metastases,
and CA19-9 levels. The median age was 63 years and 58% were men. 60% had a KPS of
90-100, 84% had liver metastases, and 39% had lung metastases. 43% of the primary
lesions were in the head of the pancreas.

[0320] The median overall survival in the intent-to-treat analysis was 8.5 months in the
Nab-paclitaxel plus gemcitabine arm compared with 6.7 months in the gemcitabine arm, with
a hazard ratio of 0.72 (95% CI from a stratified Cox model, 0.617 - 0.835), which
translated to a 28% reduction in the risk of death, p=0.000015, using a stratified
log-rank test (Figure 2 and Table 7).
[0321] Table 8 shows that treatment with
Nab-paclitaxel plus gemcitabine increased the 1-year survival rate by 59% (from 22% in
the gemcitabine arm to 35% in the
Nab-paclitaxel plus gemcitabine arm) and also doubled the 2-year survival rate (from
4% to 9%).

[0326] Figure 4 and Table 13 demonstrate that the secondary endpoint of progression free
survival was significantly improved. The median PFS was 3.7 months in the gemcitabine
arm compared with 5.5 months in the
Nab-paclitaxel plus gemcitabine arm, with a hazard ratio of 0.69, corresponding to a
31% reduction of the risk of progression or death (95% CI, 0.581 - 0.821; p = 0.000024,
stratified log-rank test). Nine and twelve month PFS rates were doubled in the
Nab-paclitaxel plus gemcitabine arm. The absolute improvement in median PFS of 1.8 months
was identical to the absolute improvement in median overall survival.

[0334] The median dose intensity of gemcitabine was only about 10% lower in the
Nab-paclitaxel plus gemcitabine arm, indicating that Abraxane® allows adequate dosing
of gemcitabine (Table 18). The Abraxane® dose intensity delivered was 80% of the planned
dose, which was high (Table 18).

[0337] The Grade 3-4 adverse events that were seen in a higher percentage of patients in
the
Nab-paclitaxel plus gemcitabine arm were neutropenia, fatigue, peripheral neuropathy,
thrombocytopenia, anemia, dehydration, nausea, and diarrhea. The rate of grade 3-4
neuropathy was 17% (Table 21). By central lab, there was a higher rate of grade 3-4
neutropenia and thrombocytopenia, but no difference in anemia (Table 21).

[0341] In this multinational, multi-institutional study carried out in a highly representative
patient population,
Nab-paclitaxel plus gemcitabine provides a robust, highly significant improvement in
survival compared with gemcitabine alone for patients with metastatic pancreatic cancer.
Nab-paclitaxel plus gemcitabine is the first chemotherapy doublet to significantly improve
survival in metastatic pancreatic cancer, with a median overall survival of 8.5 months
in the
Nab-paclitaxel plus gemcitabine arm versus 6.7 months in the gemcitabine arm (HR = 0.72,
p=0.0000152). Treatment with
Nab-paclitaxel plus gemcitabine resulted in a 59% increase in one year survival, from
22% in the gemcitabine arm to 35% in the
Nab-paclitaxel plus gemcitabine arm, and doubled the two-year survival rate (4% to 9%).
[0342] Independently reviewed secondary endpoints demonstrated consistent and significant
improvements, with median progression-free survival of 5.5 months in the
Nab-paclitaxel plus gemcitabine arm versus 3.7 months in the gemcitabine arm (HR = 0.69,
p=0.000024), an objective response rate (ORR) of 23% (compared to 7% for the gemcitabine
arm), an ORR ratio of 3.19 (
P = 1.1 x 10
-10). Serious life-threatening toxicity was not increased and adverse events were acceptable
and manageable. The results of this study were consistent across subgroups, and supported
by all efficacy endpoints, demonstrating
Nab-paclitaxel plus gemcitabine is superior to gemcitabine alone in the treatment of
metastatic pancreatic cancer.
Example 2. Updated Survival from a Randomized Phase III Trial (MPACT) of nab-Paclitaxel
Plus Gemcitabine Versus Gemcitabine Alone for Patients With Metastatic Adenocarcinoma
of the Pancreas
[0343] This Example provides an updated analysis of OS from the MPACT trial (described in
Example 1), which compared
Nab-paclitaxel plus gemcitabine administered weekly to standard treatment (gemcitabine
monotherapy) with respect to overall survival (OS), progression-free survival (PFS),
and tumor response in patients diagnosed with metastatic adenocarcinoma of the pancreas.
The updated overall survival as of May 9, 2013 is shown in Figure 9. The median OS
for patients receiving
Nab-paclitaxel plus gemcitabine was significantly longer than the median OS for patients
receiving gemcitabine alone. Longer follow-up demonstrated a median OS difference
of 2.1 months between the treatment arms. As shown in Table 26 below, 4% of patients
in the
Nab-paclitaxel plus gemcitabine arm survived three or more years.

[0345] As shown in Table 29 above, a higher proportion of patients with elevated baseline
CA19-9 levels (≥ 59 × ULN) were alive at 2-3 years with
Nab-paclitaxel plus gemcitabine as compared to gemcitabine alone.
[0346] Patients receiving
Nab-paclitaxel plus gemcitabine demonstrated a similar survival regardless of CA 19-9
levels at baseline; however, patients with greater than median CA 19-9 levels at baseline
had worse survival with gemcitabine alone than patients with less than median CA 19-9
levels. See Figure 11.
[0347] No new safety signals were observed for either treatment arm. The most common grade
≥ 3 toxicities were neutropenia, leukopenia, peripheral neuropathy, and fatigue. The
following notable toxicities in
Nab-paclitaxel plus gemcitabine arm were observed: 17% of patients had grade 3 peripheral
neuropathy (no cases of grade 4; 54% had any-grade peripheral neuropathy). The median
time to improvement of grade 3 peripheral neuropathy to grade ≤ 1 was 29 days, and
44% of patients resumed treatment with
Nab-paclitaxel. Grade ≥ 3 fatigue occurred in 17% of patients. See Table 30 below.

Example 3. Analysis of Metabolic Response by Positron Emission Tomography Compared
With Tumor Response by Computed Tomography From MPACT, a Phase III Trial Comparing
nab-Paclitaxel Plus Gemcitabine vs Gemcitabine Alone for Patients With Metastatic
Adenocarcinoma of the Pancreas.
[0348] Positron emission tomography (PET) scan using [
18F] 2-fluoro-2-deoxyglucose (
18F-FDG), is a tool in cancer management for evaluating response assessment in various
malignant tumors. The differences in metabolic response (MR) by PET between treatment
arms and the relationships between MR and other endpoints and markers of efficacy
in the MPACT trial were examined.
[0349] The study design for the present Example is described above in Example 1. A total
of 861 patients were randomized between May, 2009 and April, 2012 in 151 community
and academic centers from 11 countries. With 608 events, there was 90% power to detect
OS, HR 0.769 (2-sided α = 0.049). Treatment continued until disease progression. CT
scans were performed at baseline and every 8 weeks. PET scans were performed at baseline,
week 8, and week 16. The primary endpoint of this study was overall survival (OS).
The secondary endpoints were progression-free survival (PFS) and overall response
rate (ORR) by independent review using
Response Evaluation Criteria In Solid Tumors (RECIST) v1.0 criteria and safety. PET analysis was a prespecified exploratory objective
[0350] As shown in Figure 12, a total of 257 patients underwent PET scans at baseline. Week
8 PET scans were performed in 218 patients, and week 16 PET scans were performed in
131 patients
[0351] Over 60% of patients had 5 or 6 PET-avid lesions at baseline.
See Table 31 below. The median maximum standardized uptake (SUV
max) values at baseline were 18.0 in the
Nab-paclitaxel plus gemcitabine arm and 19.7 in the gemcitabine alone arm. Metabolic rate
(MR) rate by PET was significantly higher for the
Nab-paclitaxel plus gemcitabine arm as compared to the gemcitabine alone arm (Table 31).
ORR, OS, and PFS were also significantly better for the
Nab-paclitaxel plus gemcitabine arm compared to the gemcitabine alone arm in the cohort
of patients who had PET scans at baseline (Table 31)

[0352] In a pooled-treatment-arm analysis, 130 of 255 total patients (51%) had a metabolic
response by PET. Most patients who had a response by RECIST also had a response by
PET (42/54 = 78%; Table 32 below). Many of the patients who did not experience a response
by RECIST did have a response by PET (115/203 = 57%; Table 32 below). Among patients
with an MR by PET, 32% had a complete response (CR) or partial response (PR), 43%
had stable disease (SD), and 16% had progressive disease (PD) by RECIST. The median
OS for patients who did not have a response by RECIST (n = 88) but did have a response
by PET was 10 months (Table 32 below).

[0353] Consistent with the percentages of patients who demonstrated metabolic responses
by
European Organization for Research and Treatment of Cancer (EORTC) criteria, the per-patient decrease in FDG uptake at both week 8 and week
16 was greater in the
Nab-paclitaxel plus gemcitabine arm (Table 33).

[0354] In both treatment arms, the percentages of patients with a RECIST-defined response
were higher in the groups of patients with the greatest per-patient decreases in FDG
uptake (Table 34). Twelve percent of patients in the
Nab-paclitaxel plus gemcitabine arm and 25% of patients in the gemcitabine alone arm
had decreases in FDG uptake at week 8 but had progressive disease by RECIST (Table
34).

[0355] In summary, the high number of patients with PET-avid tumors (> 60% of patients with
5 or 6 PET-avid lesions at baseline) and high median SUV
max values at baseline demonstrate that pancreatic cancer lesions were, indeed, PET-avid.
Consistent with other efficacy results, PET results favored nab-P + Gem over Gem alone,
i.e., higher metabolic response rate: 63% vs 38% and greater reduction in FDG uptake at
weeks 8 and 16 (week 8: median decrease 41.2% vs 28.6%, week 16: median decrease 49.1%
vs 28.6%). Rates of MR by PET in this trial were > 2-fold the response rates by RECIST,
suggesting that PET may be a more sensitive marker of tumor response. Because response
by PET at weeks 8 and 16 served as a surrogate for clinical efficacy in this trial,
it may be desirable to examine PET response at even earlier time points that would
allow PET data to inform treatment plans. Of the patients without a CR or PR by RECIST,
those with an MR by PET had a longer median OS vs those without one. A set of patients
who had PD by RECIST exhibited an MR by PET. Thus, PET may identify a set of patients
who could benefit from continued treatment despite SD or PD by CT.
