CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of the U.S. Provisional Patent Application No. 60/932,750 filed on Jun. 1, 2007, the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present invention relates to methods and compositions for the treatment of recurrent cancer, particularly recurrent ovarian cancer, comprising the administration of compositions comprising nanoparticles comprising taxane and a carrier protein (such as albumin).

BACKGROUND

Ovarian cancer forms in tissues of an ovary (one of a pair of female reproductive glands in which the ova, or eggs, are formed). Most ovarian cancers are either ovarian epithelial carcinomas (cancer that begins in the cells on the surface of the ovary) or malignant germ cell tumors (cancer that begins in egg cells). According to the National Cancer Institute, ovarian cancer is the seventh most common cancer, with an estimated 20,180 new cases in 2006, but is the fourth most deadly, with an estimated 15,310 deaths in 2006.

A possible genetic contribution to ovarian cancer risk is indicated by the increased incidence of this cancer among women with a family history, and by the observation of rare families in which multiple family members are affected with ovarian cancer, in a pattern compatible with autosomal dominant inheritance of cancer susceptibility. Formal studies of families (linkage analysis) have subsequently proven the existence of autosomal dominant predispositions to ovarian cancer and have led to the identification of several highly penetrant genes as the cause of inherited cancer risk in many cancer-prone families. Mutations in these genes are rare in the general population and are estimated to account for no more than 5% to 10% of ovarian cancer cases overall.

Although reproductive, demographic, and lifestyle factors affect risk of ovarian cancer, the single greatest ovarian cancer risk factor is a family history of the disease. A large meta-analysis of 15 published studies estimated an odds ratio (OR) of 3.1 for the risk of ovarian cancer associated with at least one first-degree relative with ovarian cancer.

Despite recent improvements, initial or first-line chemotherapy fails to produce a remission in more than 70% of patients with ovarian cancer. Furthermore, approximately 40-50% of the women who do achieve a remission after first-line chemotherapy will experience a recurrence of cancer within 3 years. Patients with recurrent ovarian, peritoneal, or fallopian tube cancer generally have a poor outcome with current therapies. There is a need for effective treatment method for patients with recurrent ovarian cancers. Preferably, the treatments overcome the shortcomings of current drug and transplant treatments, such as hypersensitivity reactions due to the solvent/surfactant in which drugs are dissolved.

Many anti-proliferative agents are dissolved in a solvent/surfactant which produces hypersensitivity reactions. Great efforts have been invested on the development of water soluble prodrugs and derivatives of anti-proliferative agents with higher hydrophilic groups to enhance water solubility and thus obviate the need for potentially toxic solvents/surfactants. Another approach to address the problem associated with the poor water solubility of anti-proliferative agents is the development of various formulations such as nanoparticles, oil-in-water emulsions, and liposomes. For example, Abraxane® is a nanoparticle composition of paclitaxel and albumin. Nanoparticle compositions of substantially poorly water soluble drugs and uses thereof have been disclosed, for example, in U.S. Pat. Nos. 5,916,596; 6,096,331; 6,749,868; and 6,537,579; U.S. Patent Appln. Pub. No. US20030199425; and PCT Application Pub. Nos. WO98/14174, WO99/00113, WO07/027,941 and WO07/027,819. Administration of Abraxane® to a patient with recurrent ovarian cancer is described in Mida et al., Gynecologic Oncology, 100:437-438 (2006).

BRIEF

SUMMARY

OF THE INVENTION

The present invention provides methods for the treatment of a recurrent cancer (such as a recurrent gynecological cancer) by administering a composition comprising nanoparticles comprising a taxane and a carrier protein (hereinafter referred to as “taxane nanoparticle composition”). In some embodiments, there is provided a method of treating a recurrent cancer (such as a recurrent gynecological cancer, for example recurrent ovarian, peritoneal, or fallopian tube cancer) in an individual, comprising administering to the individual an effective amount of a composition comprising nanoparticles comprising a taxane (such as paclitaxel) and a carrier protein (such as albumin). In some embodiments, the recurrent cancer (such as a recurrent gynecological cancer, for example recurrent ovarian, peritoneal, or fallopian tube cancer) is platinum sensitive. In some embodiments, the recurrent cancer (such as a recurrent gynecological cancer, for example recurrent ovarian, peritoneal, or fallopian tube cancer) is platinum resistant. In some embodiments, the recurrent cancer is a recurrent lung cancer.

In some embodiments, the recurrent cancer is a recurrent gynecological cancer. In some embodiments, the recurrent gynecological cancer is a recurrent ovarian cancer (such as a recurrent epithelial ovarian cancer). In some embodiments, the recurrent gynecological cancer is a recurrent peritoneal cancer. In some embodiments, the recurrent gynecological cancer is a recurrent fallopian tube cancer (including for example papillary serous adenocarcinomas, sarcomas, and transitional cell carcinomas). Other recurrent gynecological cancers such as recurrent malignant mixed mullerian tumor and serous endo can also be treated.

In some embodiments, the individual is a woman who is about 40 to about 85 years old, including for example about 60 to about 70 years old. In some embodiments, the individual has an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 (such as any of 0, 1, or 2) prior to the administration of the taxane nanoparticle composition. In some embodiments, the individual has received a prior cancer therapy (such as chemotherapy) and has a treatment free interval for more than about any of 3, 6, or 9 months since the completion of prior chemotherapy. In some embodiments, the individual has received a prior cancer therapy (such as chemotherapy) and has a treatment free interval for more than about any of 12, 18, 24, 36, or 48 months since the completion of prior chemotherapy. In some embodiments, the prior chemotherapy has a different mechanism of action than that of the taxane. In some embodiments, the individual has only been treated with platinum-based agent(s) prior to the administration of the taxane nanoparticle composition. In some embodiments, the individual has only been treated with one dosing regime prior to the administration of the taxane nanoparticle composition. In some embodiments, the individual has not previously been treated with a taxane-based therapy.

In some embodiments, the individual has received a prior cancer therapy (such as chemotherapy) and has a treatment free interval for more than about any of 3, 6, or 9 months prior to the initiation of the methods described herein. In some embodiments, the individual has received a prior cancer therapy (such as chemotherapy) and has a treatment free interval for more than about any of 12, 18, 24, 36, or 48 months prior to the initiation of the methods described herein. In some embodiments, the individual does not show a symptom of hypersensitivity (such as neuropathy) prior to the initiation of the methods described herein (such as within 12, 9, 6, 5, 4, 3, 2, or 1 month prior to the initiation of the methods described herein). In some embodiments, the individual does not show a symptom of hypersensitivity throughout the treatment period with methods described herein. In some embodiments, the individual does not show a symptom of hypersensitivity upon completion of the treatment with methods described herein.

In some embodiments when the method is directed to treatment of a recurrent ovarian, peritoneal, or fallopian tube cancer, the individual may be confirmed of having an ovarian, peritoneal, or fallopian tube cancer histologically or cytologically. In some embodiments, the individual is determined to have an ovarian, peritoneal, or fallopian tube cancer based on RECIST (Response Evaluation Criteria in Solid Tumors). In some embodiments, the individual has an elevated blood level of Cancer Antigen 125 (CA-125, for example a CA-125 level of more than about 40, 50, 60, 70, 80, or 90 units/ml, or about 2×, 3×, 4×, or more of that of the upper limit of a normal CA-125 level). In some embodiments, the individual has an altered level of a marker that is indicative of an ovarian, peritoneal, or fallopian tube cancer.

In some embodiments, the individual satisfies at least two of the criteria described above. For example, in some embodiments, the individual has a measurable disease by RECIST and an elevated blood level of CA-125. In some embodiments, the individual is confirmed of having an ovarian cancer histologically or cytologically and has only been treated with platinum-based agent(s) prior to administration of the nanoparticle compositions described above. In some embodiments, the individual satisfies at least any of two, three, four, five, or more criteria described above. In some embodiments, the individual satisfies all criteria described above.

In some embodiments, the recurrent cancer (such as recurrent ovarian cancer) is platinum-sensitive. For example, in some embodiments, the individual has received prior platinum-based chemotherapy and has a treatment-free interval for more than about any of 3, 6, or 9 months since the completion of the platinum-based chemotherapy. In some embodiments, the individual has received prior platinum-based chemotherapy and has a treatment-free interval for more than about any of 12, 18, 24, 36, or 48 months since the completion of the platinum-based chemotherapy.

DETAILED DESCRIPTION

OF THE INVENTION

The present invention provides methods for the treatment of a recurrent cancer (such as recurrent gynecological cancer) comprising administering to the individual an effective amount of a composition comprising nanoparticles comprising a taxane (such as paclitaxel) and a carrier protein (such as albumin). Specifically, we have shown that a composition comprising nanoparticles comprising a taxane and a carrier protein (hereinafter designated as a “taxane nanoparticle composition”), particularly, a composition comprising nanoparticles comprising paclitaxel and albumin, more particularly, a composition comprising nanoparticles albumin bound paclitaxel (“Nab-paclitaxel”), was very active as a single agent or in combination with a platinum-based agent (carboplatin) in patients with platinum sensitive recurrent gynecological cancer, including recurrent ovarian, peritoneal, or fallopian tube cancer. The overall response rate for the treatment was 64% and the clinical benefit rate was 77%. Complete response was attained in about 70% patients treated with Abraxane® and carboplatin. This demonstrates that a taxane nanoparticle composition is particularly suitable (either as a single agent or in combination with a platinum-based agent) for treating platinum-sensitive recurrent cancer, particularly recurrent gynecological cancer.

Accordingly, the present invention in one aspect provides a method of treating a platinum-sensitive recurrent cancer comprising administering to the individual an effective amount of a composition (such as Nab-paclitaxel or Abraxane®) comprising nanoparticles comprising a taxane (such as paclitaxel) and a carrier protein (such as albumin). In another aspect, there is provided a method of treating a recurrent ovarian cancer (such as platinum-sensitive recurrent ovarian cancer) comprising administering to the individual an effective amount of a composition (such as Nab-paclitaxel or Abraxane®) comprising nanoparticles comprising a taxane (such as paclitaxel) and a carrier protein (such as albumin).

DEFINITIONS

As used herein, “the composition” or “compositions” includes and is applicable to compositions of the invention. The invention also provides pharmaceutical compositions comprising the components described herein.

Reference to “taxane” herein applies to a taxane or its derivatives and accordingly the invention contemplates and includes all these variations. Reference to “taxane” is to simplify the description and is exemplary. Taxanes include, but are not limited to, compounds that are structurally similar to or are in the same general chemical class such as paclitaxel (i.e., taxol), docetaxel (i.e., taxotere), or ortataxel, and pharmaceutically acceptable salts, derivatives, or analogs of paclitaxel, docetaxel, and ortataxel. Taxanes are antimicrobial agents that inhibit cell replication by promoting the assembly and stabilization of microtubule from tubulin dimers

Unless clearly indicated otherwise, “an individual” as used herein refers to human.

As used herein, “treatment” or “treating” is an approach for obtaining beneficial or desired results including clinical results. For purposes of this invention, beneficial or desired clinical results include, but are not limited to, one or more of the following: decreasing one or more symptoms resulting from the disease, diminishing the extent of the disease, stabilizing the disease (e.g., preventing or delaying the worsening of the disease), delay or slowing the progression of the disease, ameliorating the disease state, decreasing the dose of one or more other medications required to treat the disease, increasing the quality of life, and/or prolonging survival (including overall survival and progression free survival. In some embodiments, the composition reduces the severity of one or more symptoms associated with cancer by at least about any of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 100% compared to the corresponding symptom in the same subject prior to treatment or compared to the corresponding symptom in other subjects not receiving the composition. Also encompassed by “treatment” is a reduction of pathological consequence of cancer. The methods of the invention contemplate any one or more of these aspects of treatment.

As used herein, “delaying” the development of cancer means to defer, hinder, slow, retard, stabilize, and/or postpone development of the disease. This delay can be of varying lengths of time, depending on the history of the disease and/or individual being treated. As is evident to one skilled in the art, a sufficient or significant delay can, in effect, encompass prevention, in that the individual does not develop the disease. A method that “delays” development of cancer is a method that reduces probability of disease development in a given time frame and/or reduces the extent of the disease in a given time frame, when compared to not using the method. Such comparisons are typically based on clinical studies, using a statistically significant number of subjects. Cancer development can be detectable using standard methods, such as routine physical exams or x-ray. Development may also refer to disease progression that may be initially undetectable and includes occurrence and onset.
