TECHNICAL FIELD

The present invention relates to methods and compositions for the treatment of proliferative diseases comprising the administration of a combination of a taxane and at least one other therapeutic agent useful in the treatment of proliferative diseases.

BACKGROUND

Cancer is a leading cause of death world wide. Despite significant advances in the field of chemotherapy, many of the most prevalent forms of cancer still resist chemotherapeutic intervention.

Breast cancer is the most prevalent form of cancer in women. In 2009, an estimated 192,370 new cases of invasive breast cancer were expected to be diagnosed in women in the U.S., along with 62,280 new cases of non-invasive (in situ) breast cancer. About 40,170 women in the U.S. were expected to die in 2009 from breast cancer.

Triple-negative breast cancer is a subtype of breast cancer that is clinically negative for expression of estrogen receptor (ER), progesterone receptors (PR) and HER2 protein. Because triple-negative breast cancer cells do not express any of these receptors, they are generally unresponsive to standard receptor-mediated treatments. Chemotherapy is currently the most effective treatment for patients with triple negative breast cancer. However, many patients continue to suffer recurrence and death despite aggressive therapy, emphasizing the need for new therapeutic strategies.

Epigenetic alternations in the genome contribute to cancer initiation and progression. For example, histone hypoacetylation and abnormal DNA methylation in promoter regions of important genes can lead to gene silencing. Multiple genes are methylated and thus silenced in breast cancer. Pu RT. Mod. Path., 2003. The functions of epigenetic modifiers in treating various cancers have been investigated. Cooper et al., Gynecol. Oncol. 2007, 104(3):596-601; Ramalingam et al., J. Clin. Oncology, 2006 ASCO Annual Meeting Proceedings, Part I., Vol. 24 (18S); and Kim M S, Cancer Res 2003.

Taxanes (such as paclitaxel and docetaxel) have been shown to have significant antineoplastic and anticancer effects in a wide variety of cancers. For example, paclitaxel acts by interfering with the normal function of microtubule breakdown. Paclitaxel binds to the beta subunit of tubulin, the building blocks of microtubules, causing hyper-stabilization of the microtubule structures. The resulting paclitaxel/microtubule structure is unable to disassemble, thereby arresting mitosis and inhibiting angiogenesis. The poor aqueous solubility for the taxanes, however, presents significant challenges for developing effective taxane-based cancer therapeutics. Furthermore, the interaction of different taxane formulations with other therapeutic agents in the combination therapy context remains to be studied.

Albumin-based nanoparticle compositions have been developed as a drug delivery system for delivering substantially water insoluble drugs such as taxanes. See, for example, U.S. Pat. Nos. 5,916,596; 6,506,405; 6,749,868, and 6,537,579, and 7,820,788 and also in U.S. Pat. Pub. Nos. 2007/0082838. The albumin-based nanoparticle technology utilizes the natural properties of the protein albumin to transport and deliver substantially water insoluble drugs to the site of disease. These nanoparticles are readily incorporated into the body's own transport processes and are able to exploit the tumors' attraction to albumin, enabling the delivery of higher concentrations of the active drug encapsulated in the nanoparticles to the target site. In addition, the albumin-based nanoparticle technology offers the ability to improve a drug's solubility by avoiding the need for toxic chemicals, such as solvents, in the administration process, thus potentially improving safety through the elimination of solvent-related side effects.

BRIEF SUMMARY OF THE INVENTION

The invention provides combination therapy methods of treating a proliferative disease (such as cancer), comprising administering to the individual a) an effective amount of a composition comprising nanoparticles comprising a taxane (such as paclitaxel) and a carrier protein (such as albumin), and b) an effective amount of at least one other agent that modifies the epigenetics in a cell (also referred herein as an â€œepigenetic modifierâ€ or â€œthe other agentâ€ ). In some embodiments, the invention provides a method of treating a proliferative disease (such as cancer) in an individual comprising administering to the individual a) an effective amount of a composition comprising nanoparticles comprising paclitaxel coated with an albumin (such as AbraxaneÂ® or â€œnab-paclitaxelâ€ ), and b) an effective amount of at least one other agent that modifies the epigenetics in a cell. In some embodiments, the other agent modifies (such as inhibits) DNA methylation. In some embodiments, the other agent modifies histone modification, which includes, but is not limited to, histone acetylation, histone methylation, histone sumoylation, and histone phosphorylation. In some embodiments, the other agent is an inhibitor of DNA methyltransferase (such as azacitidine). In some embodiments, the other agent is an inhibitor of DNA methyltransferase (such as decitabine). In some embodiments, the other agent is an inhibitor of a histone deacetylase (such as vorinostat).

In some embodiments, the proliferative disease is resistant or refractory to the treatment of taxane when administered alone or in conjunction with an agent other than the epigenetic modifier. In some embodiments, the proliferative disease is resistant or refractory to the treatment when the epigenetic modifier is administered alone or in conjunction with an agent other than the nanoparticle composition (such as a non-nanoparticle composition of a taxane including paclitaxel).

In some embodiments, the composition comprising nanoparticles (also referred to as â€œnanoparticle compositionâ€ ) and the other agent are administered simultaneously, either in the same composition or in separate compositions. In some embodiments, the nanoparticle composition and the other agent are administered sequentially, i.e., the nanoparticle composition is administered either prior to or after the administration of the other agent.

In some embodiments, the administration of the nanoparticle composition and the other agent is concurrent, i.e., the administration period of the nanoparticle composition and that of the other agent 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 the other agent. In some embodiments, the other agent is administered for at least any of one, two, three, or four weeks after the termination of the nanoparticle composition. In some embodiments, the nanoparticle composition and the epigenetic modifier are administered over the same treatment cycles.

In some embodiments, the administration of the nanoparticle composition and the other agent are non-concurrent. For example, in some embodiments, the administration of the nanoparticle composition is terminated before the other agent is administered. In some embodiments, the administration of the other agent is terminated before the nanoparticle composition is administered.

In some embodiments, the other agent is a histone deacetylase inhibitor, including, but not limited to, vorinostat, romidepsin, panobinostat, belinostat, and entinostat. In some embodiments, the other agent is an inhibitor of DNA methyltransferase, including, but not limited to, 5-azacytidine (azacitidine or Vidaza), 5-aza-2â€²-deoxycytidine (decitabine or Dacogen), 1-Î²-D-arabinofuranosil-5-azacytosine, dihydro-5-azacytidine, antisense oligonucleotide MG98, and zebularine.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides methods of combination therapy comprising a first therapy comprising administration of nanoparticles comprising a taxane (such as paclitaxel) and a carrier protein (such as albumin) in conjunction with a second agent that modifies the epigenetics in a cell (also referred to as an â€œepigenetic modifierâ€ ).

We hypothesize that combination therapy of a nanoparticle composition comprising a taxane (such as paclitaxel) and a carrier protein (such as albumin) with an epigenetic modifier would significantly improve the efficacy of nanoparticle forms of taxane-based therapy and/or the efficacy of the epigenetic modifier.

The present application thus provides methods of combination therapy. It is to be understood by a person of ordinary skill in the art that the combination therapy methods described herein requires that one agent or composition be administered in conjunction with another agent. â€œIn conjunction withâ€ refers to administration of one treatment modality in addition to another treatment modality, such as administration of a nanoparticle composition described herein in addition to administration of the other agent to the same individual. As such, â€œin conjunction withâ€ refers to administration of one treatment modality before, during or after delivery of the other treatment modality to the individual.

The methods described herein are generally useful for treatment of proliferative diseases. As used herein, â€œtreatmentâ€ is an approach for obtaining beneficial or desired clinical results. For purposes of this invention, beneficial or desired clinical results include, but are not limited to, any one or more of: alleviation of one or more symptoms, diminishment of extent of disease, preventing or delaying spread (e.g., metastasis, for example metastasis to the lung or to the lymph node) of disease, preventing or delaying recurrence of disease, delay or slowing of disease progression, amelioration of the disease state, and remission (whether partial or total). Also encompassed by â€œtreatmentâ€ is a reduction of pathological consequence of a proliferative disease. The methods of the invention contemplate any one or more of these aspects of treatment.

An â€œagent that modifies the epigenetics in a cellâ€ or â€œepigenetic modifierâ€ refers to an agent that modifies an epigenetic status of a cell, namely, a phenotype or gene expression in the cell that is caused by mechanisms other than changes in the DNA sequence. An epigenetic status of a cell includes, for example, DNA methylation, histone modification(s) and RNA-associated silencing.

Individuals having â€œtriple negative breast cancerâ€ used herein refer to individuals who are clinically negative for expression of estrogen receptor (ER), progesterone receptors (PR) and HER2 protein.

The term â€œeffective amountâ€ used herein refers to an amount of a compound or composition sufficient to treat a specified disorder, condition or disease such as ameliorate, palliate, lessen, and/or delay one or more of its symptoms. In reference to cancers or other unwanted cell proliferation, an effective amount comprises an amount sufficient to cause a tumor to shrink and/or to decrease the growth rate of the tumor (such as to suppress tumor growth) or to prevent or delay other unwanted cell proliferation.

The term â€œindividualâ€ is a mammal, including humans. An individual includes, but is not limited to, human, bovine, horse, feline, canine, rodent, or primate. In some embodiments, the individual is human.

The methods may be practiced in an adjuvant setting. â€œAdjuvant settingâ€ refers to a clinical setting in which an individual has had a history of a proliferative disease, particularly cancer, and generally (but not necessarily) been responsive to therapy, which includes, but is not limited to, surgery (such as surgical resection), radiotherapy, and chemotherapy. However, because of their history of the proliferative disease (such as cancer), these individuals are considered at risk of development of the disease. Treatment or administration in the â€œadjuvant settingâ€ refers to a subsequent mode of treatment. The degree of risk (i.e., when an individual in the adjuvant setting is considered as â€œhigh riskâ€ or â€œlow riskâ€ ) depends upon several factors, most usually the extent of disease when first treated.

The methods provided herein may also be practiced in a â€œneoadjuvant setting,â€ i.e., the method may be carried out before the primary/definitive therapy. In some embodiments, the individual has previously been treated. In some embodiments, the individual has not previously been treated. In some embodiments, the treatment is a first line therapy.

It is understood that aspect and embodiments of the invention described herein include â€œconsistingâ€ and/or â€œconsisting essentially ofâ€ aspects and embodiments.

Reference to â€œaboutâ€ a value or parameter herein includes (and describes) variations that are directed to that value or parameter per se. For example, description referring to â€œabout Xâ€ includes description of â€œXâ€ .

As used herein and in the appended claims, the singular forms â€œa,â€ â€œor,â€ and â€œtheâ€ include plural referents unless the context clearly dictates otherwise. It is understood that aspects and variations of the invention described herein include â€œconsistingâ€ and/or â€œconsisting essentially ofâ€ aspects and variations.

Modes of Administration

The composition comprising nanoparticles comprising taxane (also referred to as â€œnanoparticle compositionâ€ ) and the other agent can be administered simultaneously (i.e., simultaneous administration) and/or sequentially (i.e., sequential administration).

In some embodiments, the nanoparticle composition and the other agent (including the specific agents described herein) are administered simultaneously. The term â€œsimultaneous administration,â€ 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).

In some embodiments, the nanoparticle composition and the other agent are administered sequentially. The term â€œsequential administrationâ€ 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 the other agent may be administered first. The nanoparticle composition and the other agent are contained in separate compositions, which may be contained in the same or different packages.

In some embodiments, the administration of the nanoparticle composition and the other agent are concurrent, i.e., the administration period of the nanoparticle composition and that of the other agent 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 the other agent. In some embodiments, the other agent is administered for at least any of one, two, three, or four weeks. In some embodiments, the administrations of the nanoparticle composition and the other agent 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 the other agent 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 the other agent 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 other agent is initiated after (for example after about any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or we months) the initiation of the administration of the nanoparticle composition. In some embodiments, the administrations of the nanoparticle composition and the other agent are initiated and terminated at about the same time. In some embodiments, the administrations of the nanoparticle composition and the other agent are initiated at about the same time and the administration of the other agent 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 the other agent stop at about the same time and the administration of the other agent is initiated after (for example after about any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or we months) the initiation of the administration of the nanoparticle composition.

In some embodiments, the administration of the nanoparticle composition and the other agent are non-concurrent. For example, in some embodiments, the administration of the nanoparticle composition is terminated before the other agent is administered. In some embodiments, the administration of the other agent 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.

The dosing frequency of the drug-containing nanoparticle composition and the other agent 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 the other agent can be administered at different dosing frequency or intervals. For example, the drug-containing nanoparticle composition can be administered weekly, while another agent can be administered more or less frequently. In some embodiments, sustained continuous release formulation of the drug-containing nanoparticle and/or other agent may be used. Various formulations and devices for achieving sustained release are known in the art. Exemplary dosing frequencies are further provided herein.

The nanoparticle composition and the other agent can be administered using the same route of administration or different routes of administration. Exemplary administration routes are further provided herein. In some embodiments (for both simultaneous and sequential administrations), the taxane in the nanoparticle composition and the other agent are administered at a predetermined ratio. For example, in some embodiments, the ratio by weight of the taxane in the nanoparticle composition and the other agent 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 the taxane in the nanoparticle composition and the other agent 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 in the nanoparticle composition and the other agent 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.

The doses required for the taxane and/or the other agent may (but not necessarily) be lower than what is normally required when each agent is administered alone. Thus, in some embodiments, a subtherapeutic amount of the drug in the nanoparticle composition and/or the other agent are administered. â€œSubtherapeutic amountâ€ or â€œsubtherapeutic levelâ€ 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 the other agent 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).

In some embodiments, enough other agent 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 drug in the nanoparticle composition is administered so as to allow reduction of the normal dose of the other agent 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, the dose of both the taxane in the nanoparticle composition and the other agent are reduced as compared to the corresponding normal dose of each when administered alone. In some embodiments, both the taxane in the nanoparticle composition and the other agent are administered at a subtherapeutic, i.e., reduced, level. In some embodiments, the dose of the nanoparticle composition and/or the other agent is substantially less than the established maximum toxic dose (MTD). For example, the dose of the nanoparticle composition and/or the other agent is less than about 50%, 40%, 30%, 20%, or 10% of the MTD.

In some embodiments, the dose of taxane and/or the dose of the other agent 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 the other agent is substantially higher than the established maximum toxic dose (MTD). For example, the dose of the nanoparticle composition and/or the other agent is more than about 50%, 40%, 30%, 20%, or 10% of the MTD of the agent when administered alone.

In some embodiments, the nanoparticles comprise the taxane (such as paclitaxel) coated with a carrier protein, such as albumin (e.g., human serum albumin). In some embodiments, the composition comprises taxane in both nanoparticle and non-nanoparticle forms, wherein at least about any one of 50%, 60%, 70%, 80%, 90%, 95%, or 99% of the taxane in the composition are in nanoparticle form. In some embodiments, the taxane 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 taxane that is substantially free of polymeric materials (such as polymeric matrix).

In some embodiments, the nanoparticle composition is substantially free (such as free) of surfactants (such as CremophorÂ®, Tween 80, or other organic solvents used for the administration of taxanes). 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. In some embodiments, the weight ratio of carrier protein (such as albumin) and taxane 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 nanoparticle composition comprises one or more of the above characteristics.

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.

The nanoparticles described herein comprise a taxane and a carrier protein. The term â€œproteinsâ€ refers to polypeptides or polymers of amino acids of any length (including full length or fragments), which may be linear or branched, comprise modified amino acids, and/or be interrupted by non-amino acids. The term also encompasses an amino acid polymer that has been modified naturally or by intervention; for example, disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation or modification. Also included within this term are, for example, polypeptides containing one or more analogs of an amino acid (including, for example, unnatural amino acids, etc.), as well as other modifications known in the art. The proteins described herein may be naturally occurring, i.e., obtained or derived from a natural source (such as blood), or synthesized (such as chemically synthesized or by synthesized by recombinant DNA techniques).

Examples of suitable carrier proteins include proteins normally found in blood or plasma, which include, but are not limited to, albumin, immunoglobulin including IgA, lipoproteins, apolipoprotein B, alpha-acid glycoprotein, beta-2-macroglobulin, thyroglobulin, transferin, fibronectin, factor VII, factor VIII, factor IX, factor X, and the like. In some embodiments, the carrier protein is non-blood protein, such as casein, Î±-lactalbumin, and Î²-lactoglobulin. The carrier proteins may either be natural in origin or synthetically prepared. In some embodiments, the pharmaceutically acceptable carrier comprises albumin, such as human serum albumin. Human serum albumin (HSA) is a highly soluble globular protein of M_r65K 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 disulphide 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, 9^thed, 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 Gamido 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)).

The carrier protein (such as albumin) in the composition generally serves as a carrier for the taxane, i.e., the carrier protein in the composition makes the taxane 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 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 (including Cremophor ELÂ® (BASF)). In some embodiments, the nanoparticle composition is substantially free (such as free) of surfactants. A composition is â€œsubstantially free of Cremophorâ€ or â€œsubstantially free of surfactantâ€ 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.

The amount of carrier protein in the composition described herein will vary depending on other components in the composition. In some embodiments, the composition comprises a carrier protein in an amount that is sufficient to stabilize the taxane in an aqueous suspension, for example, in the form of a stable colloidal suspension (such as a stable suspension of nanoparticles). In some embodiments, the carrier protein is in an amount that reduces the sedimentation rate of the taxane in an aqueous medium. For particle-containing compositions, the amount of the carrier protein also depends on the size and density of nanoparticles of the taxane.

A taxane is â€œstabilizedâ€ 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 20-25Â° C.) or refrigerated conditions (such as 4Â° 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 40Â° C.

In some embodiments, the carrier protein is present in an amount that is sufficient to stabilize the taxane in an aqueous suspension at a certain concentration. For example, the concentration of the taxane 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, about 5 mg/ml. In some embodiments, the concentration of the taxane 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, the carrier protein 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).

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 carrier protein. In some embodiments, the composition, in liquid form, comprises about 0.5% to about 5% (w/v) of carrier protein.

In some embodiments, the weight ratio of carrier protein, e.g., albumin, to the taxane 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 carrier protein to taxane will have to be optimized for different carrier protein and taxane combinations, generally the weight ratio of carrier protein, e.g., albumin, to taxane (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, the carrier protein to taxane 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 carrier protein (such as albumin) and the taxane 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.

In some embodiments, the carrier protein allows the composition to be administered to an individual (such as human) without significant side effects. In some embodiments, the carrier protein (such as albumin) is in an amount that is effective to reduce one or more side effects of administration of the taxane to a human. The term â€œreducing one or more side effects of administration of the taxaneâ€ 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 can be reduced.

In some embodiments, the composition comprises AbraxaneÂ® (nab-paclitaxel). AbraxaneÂ® is a formulation of paclitaxel stabilized by human albumin USP, which can be dispersed in directly injectable physiological solution. When dispersed in a suitable aqueous medium such as 0.9% sodium chloride injection or 5% dextrose injection, AbraxaneÂ® forms a stable colloidal suspension of paclitaxel. The mean particle size of the nanoparticles in the colloidal suspension is about 130 nanometers. Since HSA is freely soluble in water, AbraxaneÂ® can be reconstituted in a wide range of concentrations ranging from dilute (0.1 mg/ml paclitaxel) to concentrated (20 mg/ml paclitaxel), including for example about 2 mg/ml to about 8 mg/ml, about 5 mg/ml.

Methods of making nanoparticle compositions are known in the art. For example, nanoparticles containing taxanes (such as paclitaxel) and carrier protein (such as 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, 7,820,788 and also in U.S. Pat. Pub. No. 2007/0082838, 2006/0263434 and PCT Application WO08/137,148.

Briefly, the taxane (such as paclitaxel) is dissolved in an organic solvent, and the solution can be added to a human serum 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.

EXAMPLESExample 1Treatment with Carboplatin and Nab Paclitaxel (CP) with or without Vorinostat in HER2-Negative Primary Operable Breast Cancer

This study included both a run-in phase to investigate the safety of 12 weekly doses of carboplatin (â€œCâ€ ) (AUC 2) and nab-paclitaxel (â€œPâ€ ) (100 mg/m²) with vorinostat 400 mg orally (â€œpoâ€ ) daily (first 3 out of every 7 days) in women with unresected stage II-III HER2-negative breast cancer and a randomized phase II portion. The purpose of the randomized double-blind phase II study was to evaluate response and surrogate biomarkers to carboplatin and nab-paclitaxel (CP) with or without vorinostat as preoperative systemic therapy (PST) in HER2-negative primary operable breast cancer.

The primary objective of the study was to evaluate the primary pathological complete response rate (pCR). The secondary objectives of the study were to evaluate the safety of these regimens in these patients; to evaluate the clinical response rates; to correlate baseline and change (C1D15) in SUV on FDG PET with clinical and pathological response to CP +/âˆ’ vorinostat; and to correlate baseline and C1D15 markers of proliferation and apoptosis with clinical and pathological response to CP +/âˆ’ vorinostat. The exploratory objectives of the study were to compare clinical and pathological response to the regimen in women with basal-like tumors and non basal-like tumors; to evaluate baseline and change in gene methylation and expression profiles; and to evaluate baseline and change in tissue histone acetylation.

The non-randomized run-in phase occurred prior to the primary study in which 6-12 subjects were to be enrolled to confirm the dose of vorinostat to be studied. The primary study was a randomized, double-blind phase II study with a 1:1 randomization to either chemotherapy and placebo or chemotherapy and vorinostat. Eligible patients were stratified by hormone receptor status. There was no formal comparison of response rates between the two treatment arms. A sample size of 31 patients per arm would enable detection of a 25% pCR rate from a null response rate of 10% using a Simon two-stage design with 80% power and a 10% Type I error rate.

The study design is shown in FIG. 1. The eligible patients were randomized to receive either (i) 12 weekly doses of carboplatin (â€œCâ€ ) (AUC 2) and nab-paclitaxel (â€œPâ€ ) (100 mg/m²) or (ii) 12 weekly doses of carboplatin (â€œCâ€ ) (AUC 2) and nab-paclitaxel (â€œPâ€ ) (100 mg/m²) with vorinostat 400 mg orally (â€œpoâ€ ) daily (first 3 out of every 7 days). N=62 (31 participants for each arm).

Eligible women were 18 years or older awaiting definitive surgery or preoperative systemic therapy. The eligibility criteria for the study included: histologically confirmed invasive breast cancer; any EP or PR status; HER2-negative; T2, T3, or T4 lesion, any N, M0 or T1c, N1-3, M0; ECOG performance status 0-1; adequate blood counts and organ function (including ANC â‰§1,500/mm³; platelet count â‰§150,000/mm³; hemoglobin â‰§9 g/dL; creatinine â‰¦1.5 times the upper limit of normal (ULN) with creatinine clearance â‰§50 mL/min; bilirubin with normal limits; and aspartate aminotransferase (â€œASTâ€ ) and alanine aminotransferase (â€œALTâ€ ) â‰¦2.5 times (ULN)); no prior chemotherapy, radiation therapy or hormonal therapy for the current cancer.

Six women completed the run-in-phase without dose-limiting toxicities. 6 patients had been randomized in the phase II portion, 2 women completed the phase II portion. The patient characteristics are shown in Table 1.

Example 2Evaluating Response and Surrogate Biomarkers to the Treatment with Carboplatin and Nab Paclitaxel (CP) with or without Vorinostat as Preoperative Chemotherapy in HER2-Negative Primary Operable Breast Cancer

This randomized double-blind phase II trial studies the effects of the treatment of carboplatin and paclitaxel albumin-stabilized nanoparticle formulation (nab-paclitaxel) with or without vorinostat in women with breast cancer that can be removed by surgery. In addition, this study evaluates the response and surrogate biomarkers to the treatment with carboplatin and nab-P (CP) with or without vorinostat.

There are two arms for this study. Arm I is Active Comparator: patients receive carboplatin intravascular (â€œIVâ€ ) and paclitaxel albumin-stabilized nanoparticle formulation IV on day 1 and an oral placebo on days 1-3. Treatment repeats weekly for 12 weeks in the absence of disease progression or unacceptable toxicity. Drug used for Arm I are: carboplatin given IV; paclitaxel albumin-stabilized nanoparticle formulation given IV; and placebo given orally. Arm II is Experimental: patients receive carboplatin and paclitaxel albumin-stabilized nanoparticle formulation as in arm I and oral vorinostat on days 1-3. Treatment repeats weekly for 12 weeks in the absence of disease progression or unacceptable toxicity. Drug used for Arm II are: carboplatin given IV; paclitaxel albumin-stabilized nanoparticle formulation given IV; vorinostat given orally.

The primary objective of the study is to determine pathological complete response (pCR) rates in patients with HER2-negative primary operable breast cancer treated with neoadjuvant therapy comprising carboplatin and paclitaxel albumin-stabilized nanoparticle formulation (CP) with versus without vorinostat. The secondary objectives of the study are: to evaluate the safety of these regimens in these patients; to estimate clinical complete response (cCR) rates in patients treated with these regimens; to correlate baseline and change (day 15) in surrogate uptake values (SUV) on FDG-PET with pathological and clinical response in patients treated with these regimens, and to determine what percent of women with â‰§25% or â‰§50% reduction in SUV on day 15 achieve a pCR and a cCR to CP with versus without vorinostat; to correlate baseline and change in markers of proliferation with pathological and clinical response in patients treated with these regimens; and to evaluate long term outcomes (e.g., recurrence of the breast cancer, development of a new cancer, or death) for patients treated with these regimens. The tertiary objectives are: to evaluate baseline and change in candidate gene methylation and expression profiles; to evaluate baseline and change in tissue and peripheral blood mononuclear cell histone acetylation; to compare cCR and pCR in women with basal-like features versus other subtypes.

The patient eligibility for the study includes: 18 Years and older; female; no healthy volunteers. The criteria for disease characteristics include: histologically confirmed infiltrating ductal breast cancer by core needle biopsy (mixed ductal and lobular disease allowed; infiltrating lobular cancer allowed in the run-in portion only); unresected, clinically measurable disease, meeting one of the following clinical staging criteria: (i) T2, T3, or T4 lesion, any N, M0 (ii) T1c, N1-3, M0; patients with skin metastases to the ipsilateral breast for whom chemotherapy is planned prior to definitive surgery are eligible for the primary study portion; HER2-negative disease; hormone receptor status meeting one of the following criteria: (i) estrogen receptor (ER)-negative and progesterone receptor (PR)-negative (ii) ER-positive (grade II or III) and PR-positive or PR-negative (note: any ER or PR status for the run-in portion).

The patient characteristics include: ECOG performance status 0-1; menopausal status not specified; ANC â‰§1,500/mm³; platelet count â‰§150,000/mm³; hemoglobin â‰§9 g/dL; creatinine â‰¦1.5 times the upper limit of normal (ULN); creatinine clearance â‰§50 mL/min; total bilirubin normal; AST(SGOT) and ALT(SGPT) â‰¦2.5 times (ULN); alkaline phosphatase â‰¦2.5 times ULN; PT such that INR â‰¦1.5 (or an in-range INR, usually between 2 and 3, if a patient is on a stable dose of therapeutic warfarin) and PTT â‰¦ULN; Adequate cardiac function defined as no evidence of PR prolongation or AV block on baseline electrocardiogram (ECG); willing to use effective, non-hormonal contraception while on treatment and for at least 3 months thereafter; not pregnant or nursing; no pre-existing peripheral neuropathy â‰§grade 2; no history of severe hypersensitivity reaction to any drug formulated with polysorbate 80 or to E. coli-derived products; no history of allergic reactions attributed to compounds of similar chemical or biologic composition to vorinostat; no medical condition which, in the opinion of the investigator, puts the patient at risk of potentially serious complications while on this therapy

The criteria for patients' prior concurrent therapy include: at least 4 weeks since prior valproic acid or other histone deacetylase inhibitor; no prior chemotherapy, radiotherapy, or endocrine therapy for this cancer (prior tamoxifen or raloxifene or another agent for prevention of breast cancer allowed as long as the patient has discontinued the treatment â‰§1 month prior to baseline study biopsy); no systemic treatment for prior cancer within the past 5 years (primary study portion); no prior or ongoing systemic treatment for this cancer (primary study portion); no concurrent combination antiretroviral therapy for HIV-positive patients; no other concurrent histone deacetylase inhibitor; no other concurrent chemotherapy, antiestrogen therapy, radiotherapy, or other investigational systemic therapy; no other concurrent biologic therapy; no other concurrent investigational drugs.

The study comprises a randomized phase II study (primary study portion) and a 6-12 patient run-in portion. For the run-in portion, patients receive carboplatin IV and paclitaxel albumin-stabilized nanoparticle formulation IV on day 1 and oral vorinostat on days 1-3. Treatment repeats weekly for 12 weeks in the absence of disease progression or unacceptable toxicity. Once safety of the combination of chemotherapy and vorinostat is confirmed, subsequently enrolled patients are entered to the primary study portion.

For the primary study portion, patients are stratified by hormone receptor status (estrogen receptor (ER)-negative and progesterone receptor (PR)-negative vs ER-positive and/or PR-positive). Patients are randomized to 1 of 2 treatment arms. Arm I: Patients receive carboplatin IV and paclitaxel albumin-stabilized nanoparticle formulation IV on day 1 and an oral placebo on days 1-3. Treatment repeats weekly for 12 weeks in the absence of disease progression or unacceptable toxicity. Arm II: Patients receive carboplatin and paclitaxel albumin-stabilized nanoparticle formulation as in arm I and oral vorinostat on days 1-3. Treatment repeats weekly for 12 weeks in the absence of disease progression or unacceptable toxicity.

Within 2-4 weeks after completion of neoadjuvant chemotherapy, patients undergo breast conserving surgery or mastectomy at the discretion of the treating physician.

Patients undergo tumor tissue biopsy at baseline, day 15, and at the time of definitive surgery. Samples are analyzed by immunohistochemistry (IHC), RNA extraction, and gene expression analysis using RT-PCR to identify candidate markers for response and molecular profiles that may be relevant to an understanding of drug mechanisms. Methylation of relevant genes (e.g., ERalpha, APC-1, RARbeta, cyclin D2, Twist, RASSF1A, and HIN-1) are evaluated by quantitative multiplex methylation-specific PCR. Changes in gene expression as a result of treatment are determined by IHC or quantitative RT-PCR. Blood samples are collected at baseline, day 15, at the time of definitive surgery, and 4 weeks after surgery for DNA methylation studies, pharmacogenomic studies, and histone acetylation assays. Patients also undergo fludeoxyglucose F 18-positron emission tomography (FDG-PET) or PET/CT at baseline and day 15 to assess treatment response as measured by standardized uptake values.

Example 3Using FDG-PET Prior to Neoadjuvant Therapy and Post Neoadjuvant Therapy to Predict Response to the Therapy in Breast Cancer Patients

This study used functional imaging, FDG-PET, to predict response to neoadjuvant therapy in patients with early stage breast cancer. For the patients with early stage breast cancer, FDG-PET was performed at baseline and 7 days after commencement of neoadjuvant therapy in women with early breast cancer. FIG. 2 shows the FDG-PET results from 2 patients. Patient 1 (top, FIG. 2) had a right-sided breast mass (Standardized Uptake Value (â€œSUVâ€ ) of 12.4) prior to neoadjuvant therapy and a reduction in SUV to 6.7 based on FDG-PET. Patient 1 had a partial response to the therapy. Patient 2 (bottom, FIG. 2) had a left-sided breast mass (SUV of 31) prior to neoadjuvant therapy and a reduction in SUV to 9.9 based on FDG-PET. Patient 2 had a complete response to therapy.

Example 6Evaluation of the Efficacy of Intraperitoneal and Intravenous AbraxaneÂ® with and without Decitabine in an Intraperitoneal Ovarian Carcinoma Model in Athymic Mice

The objective of this study is to evaluate and compare the efficacy of intraperitoneal treatments with AbraxaneÂ® alone or with Decitabine (â€œDACâ€ ) versus intravenous AbraxaneÂ® alone or with Decitabine in an intraperitoneal model of human ovarian carcinoma (OVCAR-3) in athymic mice.

Abraxane is reconstituted with sterile 0.9% saline and then diluted to the appropriate concentration. 50 mg of lyophilized Decitabine/Dacogen is reconstituted in 20 ml of sterile saline. Store 1.5 ml aliquots frozen at âˆ’80Â° C. Prior to dosing, aliquots of the stock solution are diluted 1:10 (dilute to total volume of 15 ml) with saline to obtain 0.25 mg/ml for IP or IV dosing at 2 mg/kg (approximately 50 ml/mouse).

A total of 99 animals (at least 9 animals per test group) are used in this study to evaluate the effect of AbraxaneÂ® and DAC intraperitoneally and intravenously administered in an intraperitoneal ovarian carcinoma model. Female NCr nude mice from Taconic are used in the study. Weight: 20-30 grams on the day of implantation. Age: at least 6 weeks old on the day of randomization; btc-x8014 ovcar/2.

Tumor Injection Procedure: Each animal are weighed, and then injected intraperitoneally with 1-4Ã—106 OVCAR-3 cells. The cells are suspended in 0.5 ml of Phosphate Buffered Saline (PBS).

Test Article Dosing (IP): Animals are injected intraperitoneally (IP) with 10 ml/kg of either Abraxane or DAC or both starting 1 week after implantation. Control animals are given 10 ml/kg IP. Abraxane is administered qdx5 starting on Day 8 after cell implant (Dosing Day 1). DAC is given on days âˆ’4, âˆ’3, âˆ’2 and days 8, 9, and 10.

Test Article Dosing (IV): Animals are injected intravenously (IV) via tail vein with 10 ml/kg of either Abraxane or DAC or both starting 1 week after implantation. Control animals are given 10 ml/kg IP. Abraxane is administered qdx5 starting on Day 8 after cell implant (Dosing Day 1). DAC is given on days âˆ’4, âˆ’3, âˆ’2 and days 8, 9, and 10.

Tumor Growth Assessment: Animals are examined grossly at the time they are weighed. Observations of apparent abdominal distention and palpation for intra abdominal masses are performed and findings recorded.

Body Weights: Animals are weighed prior to tumor cell injection, then 2-3 times per week until sacrifice.

Clinical Observations: Animals are observed once daily for general appearance, cachexia, and other abnormalities.

Mortality/Morbidity: All animals are examined twice daily for mortality/morbidity. Any animal judged moribund by the study director are euthanized. Euthanized animals and any animals found dead prior to rigor mortis are necropsied, at the discretion of the Study Director and Sponsor Representative.

Necropsy: After euthanasia, ascites fluid is collected if present. Large tumors is excised and divided equally into 3 sections. One third of the tumor is placed into 10% neutral buffered formalin overnight, transferred to 95% ethanol, and stored @ room temperature for IHC analysis. The other 2 sections are dispensed into 2 separate tubes and snap frozen in liquid nitrogen for gene array and methylation analysis. Cryo tapes are used for labeling each container with black permanent markers.

Example 7A Phase I/II Study of the Hypomethylating Agent Azacitadine with the Nanoparticle Albumin Bound Paclitaxel in the Treatment of Patients with Advanced or Metastatic Solid Tumors and Breast Cancer

This study evaluates the effect of paclitaxel and azacitidine for treatment of refractory advanced or metastatic solid tumors, including lymphoma, sarcoma, ovarian, lung, endometrial, pancreatic, and breast cancer.

Patients with evaluable advanced or metastatic solid tumors, including lymphoma, adequate organ function, PS 0-2, and unlimited prior cytotoxic chemotherapies, including taxanes, were eligible. Cohorts of 3-6 patients were enrolled and treated.

Escalating doses of azacitidine (75-100 mg/m²) were administered to patients subcutaneously on days 1-5, followed by a fixed dose of paclitaxel (100 mg/mg/m²) on days 8, 15, and 22 of a 28-day cycle, for a total of 6 cycles. Serum and/or tissue samples, where appropriate, were collected for correlative studies.

Patients were initially permitted to have an unlimited number of prior chemotherapies. However, the protocol was amended to permit no more than 2 prior cytotoxic regimens after two of the first five patients experienced dose limited toxicities and dose reduction of paclitaxel occurred in 3 patients. All affected patients had 4 or more prior cytotoxic regimens. Cohort 2 was treated at the same dose level (azacitidine 75 mg/m²) with no dose limited toxicities. Cohort 3 was treated at the next dose level (azacitidine 100 mg/m²). Two of 4 had dose limited toxicities of prolonged grade 4 neutropenia. Therefore, the maximum tolerated dose (MTD) of azacitidine in this regimen is 75 mg/m². Three additional patients were treated at the MTD dose with no grade 4 toxicity in cycle 1. To date, 16 patients have enrolled in the phase I part. Two patients were removed before completing cycle 1 because of disease progression. One patient was removed after cycle 4 for noncompliance.

Clinical activity included 1 durable complete response in refractory diffuse large B cell lymphoma, 6 partial responses in ovarian and endometrial cancer, 4 stable diseases in lung, sarcoma and pancreatic cancer, 1 unconfirmed partial response in breast cancer, and 1 progressive disease in chronic lymphocytic leukemia/small lymphocytic lymphoma. Two breast cancer patients in the phase II part had unconfirmed partial responses and are still getting treatments.

The results of this study suggest that an azacitidine dose of 75 mg/m²followed by weekly doses of 100 mg/m²paclitaxel was well tolerated and seemed to result in dramatic responses in heavily pre-treated patients with cancer of diverse histology.

Example 8SPARC Expression and Methylation Status in NSCLC Cell Lines and PD NSCLC Primary Tumors

This study evaluates the expression of SPARC in NSCLC cell lines and patient-derived (PD) NSCLC specimens. SPARC expression was examined by RT PCR in 13 NSCLC cell lines and 22 PD NSCLC tumor xenografts. Specimens were considered SPARC positive when SPARC expression was 75% or more relative to the expression of the endogenous control, GAPDH. Specimens were considered as SPARC negative if SPARC expression was less than 25% to the expression of GAPDH. Levels in-between are considered SPARC intermediate. As shown in Table 3, 8 of 13 (62%) NSCLC cell lines were SPARC negative relative to the expression of internal control GAPDH. Four of 13 (31%) NSCLC cell lines were SPARC positive. For the 22 PD NSCLC xenografts, 15 of them (68%) were SPARC negative; two were SPARC intermediate. The others are SPARC positive. These results are concordant with a previous report (Suzuki, M. et al. Br J Cancer 2005 92:942-948).

Materials and Methods

Cell Lines and Minimally Passaged (Fewer than 10 Passages) Primary Patient-Derived Tumor Specimen

NSCLC cell lines (H226, H358, H441, H522, H661, H727, H1299, H1650, H1703, H2935, H460, H157, and A549) were purchased from American Type Culture Collection (Manassas, Va.) and maintained in Roswell Park Memorial Institute medium 1640 with 10% fetal bovine serum (Sigma, St Louis, Mo.), 100 units/ml penicillin, and 100 Î¼g/ml streptomycin (Cellgro, Manassas, Va.) at 37Â° C. in 5% CO₂.

All patient-derived (PD) NSCLC tumor specimens were derived from patients whose surgeries were performed at Roswell Park Cancer Institute (RPCI; Buffalo, N.Y.). Specimens were processed through the Tissue Procurement Facility for pathologic assessment. Surgical samples were obtained with informed consent from patients and under a research protocol approved by the institutional review board and the research ethics committee at RPCI. Samples were examined for presence of malignant/normal areas before transplantation into animals. Animal experiments were approved by the Institutional Animal Care and Use Committee.

Real-Time Polymerase Chain Reaction

Total RNA was extracted from the samples with Trizol reagent (Invitrogen; Carlsbad, Calif.), and first-strand complementary DNA was generated using SuperScript III First-Strand Synthesis System (Invitrogen). The forward polymerase chain reaction (PCR) amplification primer of SPARC was 5â€²-AAGATCCATGAGAATGAGAAG-3â€² (Ex8-S), and the reverse primer was 5-AAAAGCGGGTGGTGCAATG-3â€² (Ex9-AS). Semiquantitative PCR was carried out for 4 minutes at 95Â° C. for initial denaturation, followed by 33 cycles of 94Â° C. for 25 seconds, 56Â° C. for 25 seconds, and 68Â° C. for 40 seconds. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was used as endogenous control. Quantitative real-time (RT) PCR was done with SYBR GreenER qPCR superMix for ABI PRISM (Invitrogen) using ABI 7300 RT PCR system (Invitrogen), and GAPDH was used as a housekeeping gene for purpose of normalization.

Example 9Tumoral SPARC Reexpression with Demethylating Agent

The objective of this study was to determine if demethylation of the promoter region of the SPARC gene results in reexpression of the SPARC gene in cancer cells. DNA methylation in gene promoter regions is a mechanism to silence gene expression. The loss of SPARC expression in a large proportion of NSCLC specimens may be due to the methylation in the promoter region of SPARC gene was investigated. Representative samples of NSCLC cell lines or PD xenografts were treated with decitabine (5 Î¼M) in vitro for three days and promoter methylation was analyzed.

Genomic DNA was obtained from cell lines and primary tumors by using DNeasy Blood and Tissue Kit (Qiagen; Valencia, Calif.) according to the manufacturer's handbook. The DNA methylation pattern in the CpG island of SPARC was determined using the method of methylation-specific PCR (MSP) and with the EZ DNA Methylation Kit (Zymo research, Irvine, Calif.). Primers for the methylated reaction were Sparc-unmsp-F: 5â€²-TTTTTTAGATTGTTTGGAGAGTG-3â€² (sense), Sparcunmsp-R: 5â€²-AACTAACAACATAAACAAAAATATC-3â€² (antisense), sparc-msp-F: 5â€²-GAGAGCGCGTTTTGTTTGTC-3â€² (sense), and sparc-msp-R: 5â€²-AACGACGTAAACGAAAATATCG-3â€² (antisense). PCR amplification was carried out with bisulfite-treated DNA as a template using specific primer sequences for the methylated and unmethylated status of the gene. Water blanks were included with each assay. PCR amplification was carried out for 12 minutes at 94Â° C. for initial denaturation, followed by 40 cycles of 94Â° C. for 30 seconds, 58Â° C. for 25 seconds, and 68Â° C. for 45 seconds. Results were confirmed by repeating the bisulfite treatment and MSP for all samples. PCR products were visualized on 1.5% agarose gels.

Western blot analysis was carried out using standard methods. Polyclonal antihuman SPARC antibody was purchased from R&D System (Minneapolis, Minn.). NSCLC cell lines A549, H460, and H157 were treated with 5 Î¼M decitabine for 3 days in vitro and then harvested for RT-PCR and Western blot analysis. PD NSCLC xenografts and H460 xenografts treated with or without decitabine at 1.5 mg/kg/d. Xenografts were harvested for SPARC expression analysis. GAPDH were used as the endogenous control. Xenograft lysates were prepared and subjected to immunoblot analysis using 50 Î¼g of cellular protein as described previously (Yu, C. et al. Blood 2003 102:3765-3774). The levels of Î²-actin (Sigma) were measured as control for equal loading. Immunoblots were developed with enhanced chemiluminescence (Amersham Bioscience, Golden Valley, Minn.).

H226, a SPARC-positive cell line, has the highest relative SPARC expression ratio to endogenous control GAPDH (4.469, Table 3). Methylation-specific PCT (MSP) results showed that there was no methylation detected within its promoter (FIG. 3). H460, a SPARC-negative cell line (Table 3), is methylated in the SPARC promoter region, and there is weak PCR signal with the unmethylated promoter region. On treatment with decitabine, the SPARC expression is up-regulated. This is shown as the increase of unmethylated promoter of SPARC in H460 (FIG. 3), which manifested as the upregulation of SPARC protein (FIG. 4A). Similar results were also observed in vitro with NSCLC cell lines (A549, H460, and H157) and in vivo with PD xenografts (NSCLC_â€”16325 and NSCLC_â€”16384) and H460 xenograft (FIGS. 3 and 4). The loss of SPARC expression in NSCLC specimens is largely attributed to the methylation in the promoter region of SPARC gene. These results show that SPARC expression can be up-regulated by exposure to decitabine in vitro or in vivo.

Example 10Endogenous Tumor SPARC Expression and Response to AbraxaneÂ® In Vivo

This study compares the antitumor efficacy of AbraxaneÂ® with equitoxic dose of taxol in a series of PD NSCLC xenografts with different SPARC expression status. SPARC expression in tumors has been shown to facilitate the transport of albumin-bound drugs (Trieu V et al. Proc. Ann. AACR 2007 abstract 3480). AbraxaneÂ® is an albumin-bound paclitaxel. NSCLC_â€”16372 is a SPARC-positive tumor and as shown in FIG. 5A, the growth of a NSCLC_â€”16372 xenograft was suppressed by treatment with either taxol or AbraxaneÂ® compared with vehicle control. AbraxaneÂ® was more effective than taxol in inhibiting xenograft growth (p=0.0239). Similar results were observed in NSCLC_â€”15946, a SPARC-intermediate specimen. The tumor growth was significantly inhibited with either taxol (p=0.0004) or AbraxaneÂ® (p<0.0001) compared with vehicle control. Again, exposure to AbraxaneÂ® displayed a more profound growth suppression than taxol (p<0.0001; FIG. 5B). NSCLC_â€”16465 and NSCLC_â€”16591 are SPARC-negative tumors. Neither administration of taxol nor administration of AbraxaneÂ® showed any effect on tumor growth compared with vehicle control in NSCLC_â€”16,591 (p=0.3628 of taxol to vehicle; p=0.1826 of AbraxaneÂ® to vehicle; FIG. 5D). Interestingly, in NSCLC_â€”16465 xenografts, AbraxaneÂ® demonstrated significantly greater antitumor effect compared with taxol (p<0.0001), which showed no difference compared with vehicle control. AbraxaneÂ® is, thus, generally more effective than taxol at equitoxic doses in inhibiting the growth of PD NSCLC xenografts, and this effect is not consistently correlated with tumor SPARC expression status.

Reagents

AbraxaneÂ® was provided by Abraxis BioScience. Taxol was purchased from Ben Venue Labs (Bedford, Ohio). Decitabine was purchased from Sigma-Aldrich (St. Louis, Mo.). All the drugs were prepared and aliquoted and stored at âˆ’80Â° C. for use within 1 week. For decitabine experiments with NSCLC cell lines in vitro, cells were cultured in medium with DEC (5 Î¼M) for 5 days, with medium changes on days 1 and 3. Either AbraxaneÂ® or taxol was added to the changed media on day 3. Control cells were only treated with vehicle of 1% DMSO in 1 ml of media. Cells were harvested for RNA extraction, SPARC expression analysis, or cell death rate assessment on day 5.

Experiments with Tumor Xenografts In Vivo

Experimental studies were carried out using 6- to 8-week-old CB.17 severe combined immunodeficiency (SCID)/SCID with an average body weight Ëœ25 g. H460 (5Ã—10⁶cells) or PD NSCLC xenografts (mouse-to-mouse passage), which were cut into small fragments (2-3 mm in size), were implanted subcutaneously at the flank region. Tumor growth was monitored by periodic visual inspection at the site of implantation, and the dimensions of the xenografts were measured every 2 to 3 days. Tumor volume was calculated using the following formula: V=LDÃ—(SD)²/2, where V is the tumor volume, LD is the longest tumor diameter, and SD is the shortest tumor diameter.

To establish a maximally tolerated dose to be used in experiments involving pretreatment with decitabine, groups of mice implanted with H460 cell lines were tested at four dose levels of decitabine, i.e., 0.75, 1.5, 2, and 4 mg/kg, administered intraperitoneally as a single dose and monitored for viability (weight loss and death). Two mice from each group were killed 48 hours after completing decitabine treatment alone and tumor xenografts harvested to affirm SPARC-expression status. For combination drug treatment, AbraxaneÂ® was administered by tail vein injection at 30 mg/kg/d for 5 consecutive days. Taxol and decitabine were used at 13.4 mg/kg/d and 1.5 mg/kg/d, respectively. The doses for AbraxaneÂ® and taxol have been previously demonstrated to be equitoxic at these levels (Desai N et al. Clin Cancer Res 2006 12:1317-1324). At the end of drug treatment, the mice were killed. Xenografts were harvested and assayed to determine SPARC status.

Example 11Tumor SPARC Reexpression/Upregulation and Response to AbraxaneÂ® or Taxol

The study evaluates tumor SPARC expression upregulation on treatment with decitabine in vitro and in vivo. To establish a tolerable dose to be used in experiments in vivo, groups of mice implanted with H460 cell lines were tested at four dose levels of decitabine, i.e., 0.75, 1.5, 2, and 4 mg/kg, respectively. This is based on prior publication showing that decitabine administered twice daily intraperitoneally for 5 days was toxic at 10 mg/kg/dose, and 2 mg/kg dose was associated with mild toxicity (Guo, Z S et al Cancer Res 2006 22:1105-1113). There is dose-dependent reexpression of SPARC in H460 xenografts on treatment with decitabine. Nevertheless, decitabine at 2 and 4 mg/kg was toxic with 6/8 (75%) mice dead between 8 and 12 days after only one decitabine dose (without AbraxaneÂ® treatment). Decitabine dose at 1.5 mg/kg was subsequently used in the combination experiments.

To further elucidate the effect of SPARC expression status on the differential antitumor efficacy of AbraxaneÂ® in comparison with equitoxic dose of taxol in vivo, experiments in two SPARC-negative PD NSCLC primary xenografts (NSCLC_â€”16325 or NSCLC_â€”16384) and one SPARC negative established NSCLC cell line (H460) were performed. First, SPARC expression in xenografts was up-regulated on exposure to decitabine (1.5 mg/kg; FIG. 4B). Second, compared with vehicle, on treatment with either AbraxaneÂ® or taxol alone, only administration with AbraxaneÂ® in NSCLC_â€”16325 showed significant antitumor efficacy (p=0.0065). There was, however, no significant difference between AbraxaneÂ® compared with taxol in suppressing the growth of these SPARC-negative PD xenografts (p=0.4577 in NSCLC_â€”16325 and p=0.9897 of NSCLC_â€”16384; FIGS. 6A, B). Third, we found that the antitumor activities of both taxol and AbraxaneÂ® were enhanced to a similar degree by pretreatment with DEC; however, this activity did not reach statistical significance (p=0.1374 of AbraxaneÂ®+decitabine versus AbraxaneÂ® and p=0.4713 of taxol+decitabine versus taxol in 16,325; p=0.8844 of AbraxaneÂ®+decitabine versus AbraxaneÂ® and p=0.7410 of taxol+decitabine versus taxol in NSCLC_â€”16,384; FIGS. 6A, B). Finally, in H460 xenografts, AbraxaneÂ® showed superior growth-suppressing activity compared with vehicle or taxol (p=0.0002). Nevertheless, decitabine pretreatment resulted in minimal change to AbraxaneÂ® antitumor activity, whereas a synergistic effect was seen in combination with taxol (p=0.0097). Nonetheless, the tumor growth inhibition achieved by AbraxaneÂ® alone seemed greater compared with decitabine with equitoxic dose of taxol, though not statistically significant (84% of AbraxaneÂ® versus 66% of decitabine+taxol, p=0.5402) (FIG. 6C).

Pretreatment with decitabine to enhance antitumor efficacy of taxol or AbraxaneÂ® was also verified in SPARC-negative NSCLC cell lines A549 and H460 in vitro. As shown in FIG. 7, decitabine enhanced the cytotoxicity of both taxol and AbraxaneÂ® in a wide range of doses (2.5, 5, 10, 20, and 50 nM). There is no difference in the antitumor activity between taxol and AbraxaneÂ® at equimolar doses.

Methods

Cell death rate analysis: NSCLC cells were seeded into 24-well plates and treated with DMSO or agents. Cells were then harvested and stained with trypan blue and viewed under light microscope. Treated cells were harvested and resuspended in trypan blue/phosphate-buffered saline solution. The number of dead/nonviable cells (blue cells) and viable cells (white cells) were counted in representative randomly selected regions, and the ratio of blue cells to white cells is calculated as the cell deathrate (%). Each experiment was performed in triplicate at least three times.

Statistical Analysis: Data from in vitro studies are expressed as the mean and standard deviation representing results from at least three independent experiments using cells derived from separate batches of cultures. To describe the observed variability in the in vivo data and test for differences between groups, a multivariate linear model was fit to each dependent variable (tumor volume). All tests were two sided and tested at a 0.05 nominal significance level. SAS version 9.2 statistical software (Cary, N.C.) was used for all statistical analyses. Difference was considered statistically significant when the calculated p value was less than 0.05.
