The application further provides combination therapy methods of treating cancer comprising administering to an individual an effective amount of nanoparticles that comprise rapamycin or a derivative thereof and a second therapy.
BACKGROUNDThe failure of a significant number of tumors to respond to drug and/or radiation therapy is a serious problem in the treatment of cancer. In fact, this is one of the main reasons why many of the most prevalent forms of human cancer still resist effective chemotherapeutic intervention, despite certain advances in the field of chemotherapy.
Cancer is now primarily treated with one or a combination of three types of therapies: surgery, radiation, and chemotherapy. Surgery is a traditional approach in which all or part of a tumor is removed from the body. Surgery generally is only effective for treating the earlier stages of cancer: While surgery is sometimes effective in removing tumors located at certain sites, for example, in the breast, colon, and skin, it cannot be used in the treatment of tumors located in other areas, inaccessible to surgeons, nor in the treatment of disseminated neoplastic conditions such as leukemia. For more than 50% of cancer individuals, by the time they are diagnosed they are no longer candidates for effective surgical treatment. Surgical procedures may increase tumor metastases through blood circulation during surgery. Most of cancer individuals do not die from the cancer at the time of diagnosis or surgery, but rather die from the metastasis and the recurrence of the cancer.
Other therapies are also often ineffective. Radiation therapy is only effective for individuals who present with clinically localized disease at early and middle stages of cancer, and is not effective for the late stages of cancer with metastasis. Radiation is generally applied to a defined area of the subject's body which contains abnormal proliferative tissue, in order to maximize the dose absorbed by the abnormal tissue and minimize the dose absorbed by the nearby normal tissue. However, it is difficult (if not impossible) to selectively administer therapeutic radiation to the abnormal tissue. Thus, normal tissue proximate to the abnormal tissue is also exposed to potentially damaging doses of radiation throughout the course of treatment. The efficacy of radiotherapeutic techniques in destroying abnormal proliferative cells is therefore balanced by associated cytotoxic effects on nearby normal cells. Because of this, radiotherapy techniques have an inherently narrow therapeutic index which results in the inadequate treatment of most tumors. Even the best radiotherapeutic techniques may result in incomplete tumor reduction, tumor recurrence, increased tumor burden, and induction of radiation resistant tumors.
Chemotherapy involves the disruption of cell replication or cell metabolism. Chemotherapy can be effective, but there are severe side effects, e.g., vomiting, low white blood cells, loss of hair, loss of weight and other toxic effects. Because of the extremely toxic side effects, many cancer individuals cannot successfully finish a complete chemotherapy regime. Chemotherapy-induced side effects significantly impact the quality of life of the individual and may dramatically influence individual compliance with treatment. Additionally, adverse side effects associated with chemotherapeutic agents are generally the major dose-limiting toxicity in the administration of these drugs. For example, mucositis is one of the major dose limiting toxicities for several anticancer agents, including 5-FU, methotrexate, and antitumor antibiotics, such as doxorubicin. Many of these chemotherapy-induced side effects if severe may lead to hospitalization, or require treatment with analgesics for the treatment of pain. Some cancer individuals die from the chemotherapy due to poor tolerance to the chemotherapy. The extreme side effects of anticancer drugs are caused by the poor target specificity of such drugs. The drugs circulate through most normal organs of individuals as well as intended target tumors. The poor target specificity that causes side effects also decreases the efficacy of chemotherapy because only a fraction of the drugs is correctly targeted. The efficacy of chemotherapy is further decreased by poor retention of the anti-cancer drugs within the target tumors.
Another problem associated with chemotherapy is the development of drug resistance. Drug resistance is the name given to the circumstances when a disease does not respond to a treatment drug or drugs. Drug resistance can be either intrinsic, which means that disease has never been responsive to the drug or drugs, or it can be acquired, which means the disease ceases responding to a drug or drugs that the disease had previously been responsive. Combination therapy, including combination chemotherapy, has the potential advantages of both avoiding the emergence of resistant cells and to kill pre-existing cells which are already drug resistant.
Due to the limitations of current treatments for cancer, the severity and breadth of neoplasm, tumor and cancer, there remains a significant interest in and need for additional or alternative therapies for treating, stabilizing, preventing, and/or delaying cancer. Preferably, the treatments overcome the shortcomings of current surgical, chemotherapy, and radiation treatments.

The present invention also provides methods for the treatment of cancer using combination therapies. The invention provides a method of treating cancer comprising a) a first therapy comprising administering to an individual an effective amount of a composition comprising nanoparticles comprising rapamycin or a derivative thereof and a carrier protein and b) a second therapy, such as surgery, radiation, gene therapy, immunotherapy, bone marrow transplantation, stem cell transplantation, hormone therapy, targeted therapy, cryotherapy, ultrasound therapy, photodynamic therapy, and/or chemotherapy (e.g., one or more compounds or pharmaceutically acceptable salts thereof useful for treating cancer).
In some embodiments, the invention provides a method of treating cancer in an individual comprising administering to the individual a) an effective amount of a composition comprising nanoparticles comprising a rapamycin or a derivative thereof and a carrier protein and b) an effective amount of at least one other chemotherapeutic agent. In some embodiments, the chemotherapeutic agent is any of (and in some embodiments selected from the group consisting of) taxane, antimetabolites (including nucleoside analogs), platinum-based agents, alkylating agents, tyrosine kinase inhibitors, anthracycline antibiotics, vinca alkloids, proteasome inhibitors, modulators of HER2/neu, modulators of EGFR, modulators of VEGFR, and topoisomerase inhibitors. In some embodiments, the chemotherapeutic agent is a platinum-based agent, such as carboplatin. In some embodiments, the chemotherapeutic agent is a modulator of HER2/neu (such as an inhibitor of HER2/neu for example Herceptin®). In some embodiments, the chemotherapeutic agent is a modulator of EGFR (such as an inhibitor of EGFR for example Erbitux®).

In some embodiments, a taxane is not administered to the individual. In some embodiments, the taxane administered is not in a nanoparticle composition.
In some embodiments, the composition comprising nanoparticles comprising a rapamycin or a derivative thereof and a carrier protein and the chemotherapeutic agent are administered simultaneously, either in the same composition or in separate compositions. In some embodiments, the nanoparticle composition comprising a rapamycin or a derivative thereof and a carrier protein and the chemotherapeutic agent are administered sequentially, e.g., the nanoparticle composition is administered either prior to or after the administration of the chemotherapeutic agent. In some embodiments, the administration of the nanoparticle composition comprising a rapamycin or a derivative thereof and a carrier protein and the chemotherapeutic agent are concurrent, e.g., the administration period of the nanoparticle composition and that of the chemotherapeutic agent overlap with each other.

The invention also provides any of the compositions described (e.g., a composition comprising nanoparticles that comprise rapamycin or a derivative thereof and a carrier protein) for any use described herein whether in the context of use as a medicament and/or use for manufacture of a medicament. Also provided are unit dosage forms of compositions described herein, articles of manufacture comprising the inventive compositions or unit dosage forms in suitable packaging (e.g., vials or vessels including sealed vials or vessels and sterile sealed vials or vessels), and kits comprising the unit dosage forms. The invention also provides methods of making and using these compositions as described herein.
It is to be understood that one, some, or all of the properties of the various embodiments described herein may be combined to form other embodiments of the present invention.
The present invention provides methods, compositions, and kits for the treatment or prevention of cancer using nanoparticles that comprise rapamycin or a derivative thereof and a carrier protein (such as albumin). The present invention further provides methods, compositions, and kits for use in combination therapy for the treatment or prevention of cancer using nanoparticles that comprise rapamycin or a derivative thereof and a carrier protein (such as albumin). Any of these compositions can be used to treat, stabilize, prevent, and/or delay cancer.
In particular, nanoparticles comprising rapamycin (also referred to as a “nanoparticle composition”) and the carrier protein albumin were shown to significantly inhibit the growth of a human mammary carcinoma implanted into a mouse model (Example 3) and inhibit tumor growth in mice with MM1S multiple myeloma tumor xenografts (Example 12B). This albumin-containing nanoparticle formulation of rapamycin was nontoxic at the doses tested and displayed linear pharmacokinetics with respect to dose (Example 2). The nanoparticle formulation of albumin and rapamycin enhances tumor penetration through albumin receptor (gp60)-mediated binding of the SPARC protein, which is upregulated in some cancer cells (e.g., breast cancer cells). This increased specificity of Nab-rapamycin may increase the effectiveness of rapamycin and may allow lower doses of rapamycin to be used, which would minimize toxic effects from rapamycin while still inhibiting, stabilizing, preventing, or delaying tumor growth. The increased specificity may also reduce toxic side-effects from interactions of rapamycin with noncancerous cells and tissues, such as intestinal toxicity that sometimes limits the dose of rapamycin that can be given to a patient. The nanoparticle formulation of rapamycin also increases the solubility of rapamycin and allows larger doses to be used, if desired.
DefinitionsAs 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.
The term, “rapamycin” herein refers to rapamycin or its derivatives and accordingly the invention contemplates and includes all these embodiments. Rapamycin is sometimes referred to elsewhere as sirolimus, rapammune, or rapamune. Reference to “rapamycin” is to simplify the description and is exemplary. Derivatives of rapamycin include, but are not limited to, compounds that are structurally similar to rapamycin, or are in the same general chemical class as rapamycin, analogs of rapamycin, or pharmaceutically acceptable salts of rapamycin or its derivatives or analogs. In some embodiments, rapamycin or a derivative thereof increases basal AKT activity, increases AKT phosphorylation, increases PI3-kinase activity, increases the length of activation of AKT (e.g., activation induced by exogenous IGF-1), inhibits serine phosphorylation of IRS-1, inhibits IRS-1 degradation, inhibits or alters CXCR4 subcellular localization, inhibits VEGF secretion, decreases expression of cyclin D2, decreases expression of survivin, inhibits IL-6-induced multiple myeloma cell growth, inhibits cancer cell proliferation, increases apoptosis, increases cell cycle arrest, increases cleavage of poly(ADPribose) polymerase, increases cleavage of caspase-8/caspase-9, alters or inhibits signaling in the phosphatidylinositol 3-kinase/AKT/mTOR and/or cyclin D1/retinoblastoma pathways, inhibits angiogenesis, and/or inhibits osteoclast formation. In some embodiments, the derivative of rapamycin retains one or more similar biological, pharmacological, chemical and/or physical properties (including, for example, functionality) as rapamycin. In some embodiments, the rapamycin derivative has at least about any of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95% or 100% of an activity of rapamycin. For example, the decrease in the size of a tumor, the number of cancer cells, or the growth rate of a tumor caused by a rapamycin derivative is preferably at least about any of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95% or 100% of the corresponding decrease caused by the same amount of rapamycin. An exemplary rapamycin derivative includes benzoyl rapamycin, such as that disclosed in paragraph [0022] of WO 2006/089207, which is hereby incorporated by reference in its entirety. Other exemplary rapamycin derivatives include WY-090217, AY-22989, NSC-226080, SiiA-9268A, oxaazacyclohentriacontine, temsirolimus (CCI 779 (Wyeth)), everolimus (RAD 001 (Novartis)), pimecrolimus (ASM981), SDZ-RAD, SAR943, ABT-578, AP23573, and Biolimus A9.
Unless clearly indicated otherwise, “an individual” as used herein intends a mammal, including but not limited to a primate, human, bovine, horse, feline, canine, or rodent.
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 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), preventing or delaying the spread (e.g., metastasis) of the disease, preventing or delaying the occurrence or recurrence of the disease, delay or slowing the progression of the disease, ameliorating the disease state, providing a remission (whether partial or total) of the disease, decreasing the dose of one or more other medications required to treat the disease, delaying the progression of the disease, increasing the quality of life, and/or prolonging 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, mammography, imaging, or biopsy. Development may also refer to disease progression that may be initially undetectable and includes occurrence, recurrence, and onset.
As used herein, an “at risk” individual is an individual who is at risk of developing cancer. An individual “at risk” may or may not have detectable disease, and may or may not have displayed detectable disease prior to the treatment methods described herein. “At risk” denotes that an individual has one or more so-called risk factors, which are measurable parameters that correlate with development of cancer, which are described herein. An individual having one or more of these risk factors has a higher probability of developing cancer than an individual without these risk factor(s).
“Adjuvant setting” refers to a clinical setting in which an individual has had a history of cancer, and generally (but not necessarily) been responsive to therapy, which includes, but is not limited to, surgery (e.g., surgical resection), radiotherapy, and chemotherapy. However, because of their history of the 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.
“Neoadjuvant setting” refers to a clinical setting in which the method is be carried out before the primary/definitive therapy.
As used herein, by “pharmaceutically active compound” is meant a chemical compound that induces a desired effect, e.g., treating, stabilizing, preventing, and/or delaying cancer.
As used herein, by “combination therapy” is meant a first therapy that includes nanoparticles comprising rapamycin or a derivative thereof and a carrier protein in conjunction with a second therapy (e.g., radiation, surgery, or chemotherapeutic agent) useful for treating, stabilizing, preventing, and/or delaying cancer. Administration in “conjunction with” another compound includes administration in the same or different composition(s), either sequentially, simultaneously, or continuously. In some variations, the combination therapy optionally includes one or more pharmaceutically acceptable carriers or excipients, non-pharmaceutically active compounds, and/or inert substances.
The term “effective amount” intends such amount of a composition (e.g., nanoparticles that comprise rapamycin or a derivative thereof and a carrier protein), first therapy, second therapy, or a combination therapy, which in combination with its parameters of efficacy and toxicity, should be effective in a given therapeutic form based on the knowledge of the practicing specialist. In various embodiments, an effective amount of the composition or therapy may (i) reduce the number of cancer cells; (ii) reduce tumor size; (iii) inhibit, retard, slow to some extent, and preferably stop cancer cell infiltration into peripheral organs; (iv) inhibit (e.g., slow to some extent and preferably stop) tumor metastasis; (v) inhibit tumor growth; (vi) prevent or delay occurrence and/or recurrence of a tumor; and/or (vii) relieve to some extent one or more of the symptoms associated with the cancer. In various embodiments, the amount is sufficient to ameliorate, palliate, lessen, and/or delay one or more of symptoms of cancer.
In some embodiments, the amount of the composition, first therapy, second therapy, or combination therapy is an amount sufficient to decrease the size of a tumor, decrease the number of cancer cells, or decrease the growth rate of a tumor by at least about any of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95% or 100% compared to the corresponding tumor size, number of cancer cells, or tumor growth rate in the same subject prior to treatment or compared to the corresponding activity in other subjects not receiving the treatment. Standard methods can be used to measure the magnitude of this effect, such as in vitro assays with purified enzyme, cell-based assays, animal models, or human testing.
As is understood in the art, an “effective amount” may be in one or more doses, i.e., a single dose or multiple doses may be required to achieve the desired treatment endpoint. An effective amount may be considered in the context of administering one or more therapeutic agents, and a nanoparticle composition (e.g., a composition including rapamycin and a carrier protein) may be considered to be given in an effective amount if, in conjunction with one or more other agents, a desirable or beneficial result may be or is achieved. The components (e.g., the first and second therapies) in a combination therapy of the invention may be administered sequentially, simultaneously, or continuously using the same or different routes of administration for each component. Thus, an effective amount of a combination therapy includes an amount of the first therapy and an amount of the second therapy that when administered sequentially, simultaneously, or continuously produces a desired outcome.
A “therapeutically effective amount” refers to an amount of a composition (e.g., nanoparticles that comprise rapamycin or a derivative thereof and a carrier protein), first therapy, second therapy, or a combination therapy sufficient to produce a desired therapeutic outcome (e.g., reducing the severity or duration of, stabilizing the severity of, or eliminating one or more symptoms of cancer). For therapeutic use, beneficial or desired results include, e.g., decreasing one or more symptoms resulting from the disease (biochemical, histologic and/or behavioral), including its complications and intermediate pathological phenotypes presenting during development of the disease, increasing the quality of life of those suffering from the disease, decreasing the dose of other medications required to treat the disease, enhancing effect of another medication, delaying the progression of the disease, and/or prolonging survival of patients.
A “prophylactically effective amount” refers to an amount of a composition (e.g., nanoparticles that comprise rapamycin or a derivative thereof and a carrier protein), first therapy, second therapy, or a combination therapy sufficient to prevent or reduce the severity of one or more future symptoms of cancer when administered to an individual who is susceptible and/or who may develop cancer. For prophylactic use, beneficial or desired results include, e.g., results such as eliminating or reducing the risk, lessening the severity of future disease, or delaying the onset of the disease (e.g., delaying biochemical, histologic and/or behavioral symptoms of the disease, its complications, and intermediate pathological phenotypes presenting during future development of the disease).
The term “simultaneous administration,” as used herein, means that a first therapy and second therapy in a combination therapy are administered with a time separation of no more than about 15 minutes, such as no more than about any of 10, 5, or 1 minutes. When the first and second therapies are administered simultaneously, the first and second therapies may be contained in the same composition (e.g., a composition comprising both a first and second therapy) or in separate compositions (e.g., a first therapy in one composition and a second therapy is contained in another composition).
As used herein, the term “sequential administration” means that the first therapy and second therapy in a combination therapy 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 first therapy or the second therapy may be administered first. The first and second therapies are contained in separate compositions, which may be contained in the same or different packages or kits.
The term “proteins” 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, including, 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 (e.g., blood) or synthesized (e.g., chemically synthesized or by synthesized by recombinant DNA techniques). Exemplary carrier proteins are described herein.
The term “antimicrobial agent” used herein refers to an agent that is capable of inhibiting (e.g., delaying, reducing, slowing, and/or preventing) the growth of one or more microorganisms. Significant microbial growth can be measured or indicated by a number of ways known in the art, such as one or more of the following: (i) microbial growth in a composition that is enough to cause one or more adverse effects to an individual when the composition is administered to the individual; (ii) more than about 10-fold increase in microbial growth over a certain period of time (for example over a 24 hour period) upon extrinsic contamination (e.g., exposure to 10-103 colony forming units at a temperature in the range of 20 to 25° C.). Other indicia of significant microbial growth are described in U.S. Ser. No. 11/514,030, filed Aug. 30, 2006, which is hereby incorporated by reference in its entirety.
“Sugar” as used herein includes, but is not limited to, monosaccharides, disaccharides, polysaccharides, and derivatives or modifications thereof. Suitable sugars for compositions described herein include, for example, mannitol, sucrose, fructose, lactose, maltose, and trehalose.
As used herein, by “pharmaceutically acceptable” or “pharmacologically compatible” is meant a material that is not biologically or otherwise undesirable, e.g., the material may be incorporated into a pharmaceutical composition administered to a patient without causing any significant undesirable biological effects or interacting in a deleterious manner with any of the other components of the composition in which it is contained. Pharmaceutically acceptable carriers or excipients have preferably met the required standards of toxicological and manufacturing testing and/or are included on the Inactive Ingredient Guide prepared by the U.S. Food and Drug administration.
As used herein, reference to “not” a value or parameter generally means and describes “other than” a value or parameter. For example, if a taxane is not administered, it means an agent other than a taxane is administered.
Reference to “about” a value or parameter herein includes (and describes) embodiments that are directed to that value or parameter per se. For example, description referring to “about X” includes description of “X”.
As used herein and in the appended claims, the singular forms “a,” “or,” and “the” include plural referents unless the context clearly dictates otherwise. It is understood that aspect and embodiments of the invention described herein include “consisting” and/or “consisting essentially of” aspects and embodiments.

In some embodiments of any of the methods of treatment related to combination therapy described herein, treatment with the combination of the first therapy (e.g., a nanoparticle composition comprising rapamycin or a derivative thereof and a carrier protein) and the second therapy (e.g., one or more compounds useful for treating cancer) may result in an additive or even synergistic (e.g., greater than additive) result compared to administration of either therapy alone. In some embodiments, a lower amount of each pharmaceutically active compound is used as part of a combination therapy compared to the amount generally used for individual therapy. Preferably, the same or greater therapeutic benefit is achieved using a combination therapy than by using any of the individual compounds alone. In some embodiments, the same or greater therapeutic benefit is achieved using a smaller amount (e.g., a lower dose or a less frequent dosing schedule) of a pharmaceutically active compound in a combination therapy than the amount generally used for individual therapy. Preferably, the use of a small amount of pharmaceutically active compound results in a reduction in the number, severity, frequency, or duration of one or more side-effects associated with the compound.
In some embodiments of any of the methods of treatment related to combination therapy, the rapamycin or derivative thereof and the second compound (e.g., a chemotherapeutic agent and/or hormone therapeutic agent) are present in a single composition containing at least two different nanoparticles, wherein some of the nanoparticles in the composition comprise the rapamycin or derivative thereof and a carrier protein, and some of the other nanoparticles in the composition comprise a second pharmaceutically active compound and a carrier protein. In some embodiments, only the rapamycin or derivative thereof is contained in nanoparticles. In some embodiments, simultaneous administration of rapamycin or derivative thereof in the nanoparticle composition and the second compound can be combined with supplemental doses of rapamycin and/or the second compound.
In some embodiments of any of the above embodiments related to combination therapies described herein, the first and second therapies are administered simultaneously, either in the same composition or in separate compositions. In some embodiments, the first and second therapies are administered sequentially, i.e., the first therapy is administered either prior to or after the administration of the first and second therapy. In some embodiments, the administration of the first and second therapies is concurrent, i.e., the administration period of the first therapy and that of the second therapy overlap with each other. In some embodiments, the administration of the first and second therapies is non-concurrent. For example, in some embodiments, the administration of the first therapy is terminated before the second therapy is administered. In some embodiments, the administration of the second therapy is terminated before the first therapy is administered. In some embodiments, the second therapy is radiation therapy. In some embodiments, the second therapy is surgery.
In some embodiments of any of the above embodiments related to combination therapy, the cancer is early stage cancer, non-metastatic cancer, primary cancer, advanced cancer, locally advanced cancer, metastatic cancer, cancer in remission, recurrent cancer, cancer in an adjuvant setting, cancer in a neoadjuvant setting, or cancer substantially refractory to hormone therapy. In some embodiments, the cancer is a solid tumor. In some embodiments, the cancer is not a solid tumor (i.e., other than a solid tumor). In some embodiments, the cancer is a plasmacytoma. In some embodiments, the cancer is multiple myeloma, renal cell carcinoma, prostate cancer, lung cancer, melanoma, brain cancer (e.g., glioblastoma), ovarian cancer, or breast cancer. In some embodiments, the cancer is a carcinoma (i.e., other than a carcinoma). In some embodiments, the cancer is not colon cancer (i.e., other than colon cancer). In some embodiments, the cancer is not breast cancer (i.e., other than breast cancer). In some embodiments, the cancer is not ovarian cancer, prostate cancer, or brain cancer.
In some embodiments of any of the above embodiments related to combination therapy, a taxane is not administered to the individual. In some embodiments, the taxane administered is not a nanoparticle composition. In some embodiments, the nanoparticle composition comprising rapamycin or a derivative thereof is not administered in conjunction with a taxane. In some embodiments, a taxane is not administered to the individual during the time period in which the individual is receiving one or more doses of a nanoparticle composition comprising rapamycin or a derivative thereof. In some embodiments, the individual was treated with a taxane before treatment begins with a nanoparticle composition comprising rapamycin or a derivative thereof. For example, the individual may have received a taxane one or more days, weeks, months, or years before treatment begins with a nanoparticle composition comprising rapamycin or a derivative thereof. In other embodiments, the individual never receives a taxane before treatment begins with a nanoparticle composition comprising rapamycin or a derivative thereof. In some embodiments, the individual is treated with a taxane after treatment with a nanoparticle composition comprising rapamycin or derivative thereof terminates. In other embodiments, the individual is never treated with a taxane after treatment with a nanoparticle composition comprising rapamycin or derivative thereof terminates. In some embodiments, the composition, first therapy, and/or second therapy do not contain a taxane. In other embodiments, the composition, first therapy, and/or second therapy comprise a taxane.
Dosing and Method of AdministrationThe dose of the inventive composition administered to an individual (such as a human) may vary with the particular composition, the method of administration, and the particular stage of cancer being treated. The amount should be sufficient to produce a desirable response, such as a therapeutic or prophylactic response against cancer. In some embodiments, the amount of the composition is a therapeutically effective amount. In some embodiments, that amount of the composition is a prophylactically effective amount. In some embodiments, the amount of rapamycin or a derivative thereof in the composition 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 is administered to the individual.
In some embodiments, the amount of rapamycin or a derivative thereof in the composition is an amount sufficient to increase basal AKT activity, increase AKT phosphorylation, increase PI3-kinase activity, increase the length of activation of AKT (e.g., activation induced by exogenous IGF-1), inhibit serine phosphorylation of IRS-1, inhibit IRS-1 degradation, inhibit or alter CXCR4 subcellular localization, inhibit VEGF secretion, decrease expression of cyclin D2, decrease expression of survivin, inhibit IL-6-induced multiple myeloma cell growth, inhibit cancer cell proliferation, increase apoptosis, increase cell cycle arrest, increase cleavage of poly(ADPribose) polymerase, increase cleavage of caspase-8/caspase-9, alter or inhibit signaling in the phosphatidylinositol 3-kinase/AKT/mTOR and/or cyclin D1/retinoblastoma pathways, inhibit angiogenesis, and/or inhibit osteoclast formation.

In yet another aspect, the invention provides a method of treating cancer in an individual by parenterally administering to the individual (e.g., a human) an effective amount of a composition comprising nanoparticles that comprise rapamycin or a derivative thereof and a carrier protein (e.g., albumin such as human serum albumin). In some embodiments, the route of administration is intravenous, intra-arterial, intramuscular, or subcutaneous. In various embodiments, about 54 mg to about 540 mg, such as about 180 mg to about 270 mg or about 216 mg, of the rapamycin or derivative thereof is administered per dose. In some embodiments, a taxane is not contained in the composition. In some embodiments, the rapamycin or derivative thereof is the only pharmaceutically active agent for the treatment of cancer that is contained in the composition.
The compositions described herein can be administered to an individual (such as human) via various routes, including, for example, intravenous, 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 may be used. For example, the inventive composition can be administered by inhalation to treat conditions of the respiratory tract. The composition can be used to treat respiratory conditions such as pulmonary fibrosis, broncheolitis obliterans, lung cancer, bronchoalveolar carcinoma, and the like. In one embodiment of the invention, nanoparticles (such as albumin nanoparticles) of the inventive compounds can be administered by any acceptable route including, but not limited to, orally, intramuscularly, transdermally, intravenously, through an inhaler or other air borne delivery systems and the like. In some embodiments, the rapamycin or derivative thereof is not coating a stent or is not administered using a stent.
The dosing frequency of the rapamycin-containing nanoparticle composition and the second compound may be adjusted over the course of the treatment based on the judgment of the administering physician. In some embodiments, the first and second therapies are administered simultaneously, sequentially, or concurrently. When administered separately, the rapamycin-containing nanoparticle composition and the second compound can be administered at different dosing frequency or intervals. For example, the rapamycin-containing nanoparticle composition can be administered weekly, while a second compound can be administered more or less frequently. In some embodiments, sustained continuous release formulation of the rapamycin-containing nanoparticle and/or second compound may be used. Various formulations and devices for achieving sustained release are known in the art. A combination of the administration configurations described herein can be used.
Modes of Administration of Combination TherapiesIn some embodiments, the present invention provides a method of treating cancer comprising a first therapy comprising administering nanoparticles comprising rapamycin or a derivative thereof and a carrier protein (e.g., albumin) and a second therapy comprising chemotherapy and/or hormone therapy. In some embodiments, the method comprises a) a first therapy comprising administering to the individual a composition comprising nanoparticles of rapamycin and an albumin; and b) a second therapy comprising chemotherapy and/or hormone therapy.
The dose of the inventive composition administered to an individual (e.g., a human) in combination therapy may vary with the particular composition, the method of administration, and the particular stage of cancer being treated. The amount should be sufficient to produce a desirable response, such as a therapeutic or prophylactic response against cancer. In some embodiments, the amount of the composition is a therapeutically effective amount. In some embodiments, that amount of the composition is a prophylactically effective amount. In some embodiments, the amount of rapamycin or a derivative thereof in the composition is below the level that induces a toxicological effect (e.g., 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 is administered to the individual.
The composition comprising nanoparticles comprising rapamycin or a derivative thereof and a carrier protein (e.g., albumin) (also referred to as “nanoparticle composition”) and the chemotherapeutic agent and/or hormone therapeutic agent can be administered simultaneously (e.g., simultaneous administration) and/or sequentially (e.g., sequential administration).
In some embodiments, the nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agents (including the specific chemotherapeutic agents described herein) are administered simultaneously. The term “simultaneous administration,” as used herein, means that the nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic 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 rapamycin or a derivative thereof in the nanoparticles and the chemotherapeutic agent and/or hormone therapeutic agent may be contained in the same composition (e.g., a composition comprising both the nanoparticles and the chemotherapeutic agent) or in separate compositions (e.g., the nanoparticles are contained in one composition and the chemotherapeutic agent is contained in another composition). For example, rapamycin or a derivative thereof and a carrier protein (e.g., albumin) and the chemotherapeutic agent may be present in a single composition containing at least two different nanoparticles, wherein some of the nanoparticles in the composition comprise rapamycin or a derivative thereof and a carrier protein, and some of the other nanoparticles in the composition comprise the chemotherapeutic agent and a carrier protein. The invention contemplates and encompasses such compositions. In some embodiments, only rapamycin or a derivative thereof is contained in nanoparticles. In some embodiments, simultaneous administration of the rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent can be combined with supplemental doses of the rapamycin or a derivative thereof and/or the chemotherapeutic agent and/or hormone therapeutic agent.
In some embodiments, the rapamycin or a derivative thereof nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent are administered sequentially. The term “sequential administration” as used herein means that the rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic 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 rapamycin or a derivative thereof nanoparticle composition or the chemotherapeutic agent and/or hormone therapeutic agent may be administered first. The rapamycin or a derivative thereof nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent are contained in separate compositions, which may be contained in the same or different packages.
In some embodiments, the administration of the rapamycin or a derivative thereof nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent are concurrent, e.g., the administration period of the nanoparticle composition and that of the chemotherapeutic agent and/or hormone therapeutic agent overlap with each other. In some embodiments, the administration of the rapamycin or a derivative thereof nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent are non-concurrent. For example, in some embodiments, the administration of the rapamycin or a derivative thereof nanoparticle composition is terminated before the chemotherapeutic agent and/or hormone therapy is administered. In some embodiments, the administration of the chemotherapeutic agent and/or hormone therapy is terminated before the rapamycin or a derivative thereof 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 rapamycin or a derivative thereof-containing nanoparticle composition and the chemotherapeutic agent and/or hormone therapy may be adjusted over the course of the treatment, based on the judgment of the administering physician. When administered separately, the rapamycin or a derivative thereof-containing nanoparticle composition and the chemotherapeutic agent and/or hormone therapy can be administered at different dosing frequency or intervals. For example, the rapamycin or a derivative thereof-containing nanoparticle composition can be administered weekly, while a chemotherapeutic agent and/or hormone therapeutic agent can be administered more or less frequently. In some embodiments, sustained continuous release formulation of the rapamycin or a derivative thereof-containing nanoparticle and/or chemotherapeutic agent and/or hormone therapeutic agent may be used. Various formulations and devices for achieving sustained release are known in the art.
The rapamycin or a derivative thereof nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent can be administered using the same route of administration or different routes of administration. In some embodiments (for both simultaneous and sequential administrations), the rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent are administered at a predetermined ratio. For example, in some embodiments, the ratio by weight of the rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent or the hormone therapeutic 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 rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent or hormone therapeutic agent is less than any of about 100:1, 50:1, 30:1, 10:1, 9:1, 8:1, 7.5:1, 7:1, 6:1, 5:1, 4:1, 3:1, 2:1, and 1:1. In some embodiments, the ratio by weight of the rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent or hormone therapeutic agent is more than any of about 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 7.5:1, 8:1, 9:1, 30:1, 50:1, 100:1. Other ratios are contemplated.
The doses required for the rapamycin or a derivative thereof and/or the chemotherapeutic agent and/or hormone therapeutic 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 rapamycin or a derivative thereof in the nanoparticle composition and/or the chemotherapeutic agent and/or hormone therapeutic agent are administered. “Subtherapeutic amount” or “subtherapeutic level” refer to an amount that is less than the therapeutic amount, that is, less than the amount normally used when the rapamycin or a derivative thereof in the nanoparticle composition and/or the chemotherapeutic agent and/or hormone therapeutic 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 chemotherapeutic agent and/or hormone therapeutic agent is administered so as to allow reduction of the normal dose of the rapamycin or a derivative thereof 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 rapamycin or a derivative thereof in the nanoparticle composition is administered so as to allow reduction of the normal dose of the chemotherapeutic agent and/or hormone therapeutic agent required to affect 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 rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent are reduced as compared to the corresponding normal dose of each when administered alone. In some embodiments, both the rapamycin or a derivative thereof in the nanoparticle composition and the chemotherapeutic agent and/or hormone therapeutic agent are administered at a subtherapeutic, e.g., reduced level. In some embodiments, the dose of the nanoparticle composition and/or the chemotherapeutic agent is substantially less than the established maximum toxic dose (MTD). For example, the dose of the rapamycin or a derivative thereof nanoparticle composition and/or the chemotherapeutic agent and/or hormone therapeutic agent is less than about 50%, 40%, 30%, 20%, or 10% of the MTD.
A combination of the administration configurations described herein can be used. The combination therapy methods described herein may be performed alone or in conjunction with another therapy, such as surgery, radiation, gene therapy, immunotherapy, bone marrow transplantation, stem cell transplantation, hormone therapy, targeted therapy, cryotherapy, ultrasound therapy, photodynamic therapy, and/or chemotherapy and the like. Additionally, a person having a greater risk of developing the proliferative disease may receive treatments to inhibit or and/or delay the development of the disease.
As will be understood by those of ordinary skill in the art, the appropriate doses of chemotherapeutic agents and/or hormone therapeutic agent will be approximately those already employed in clinical therapies wherein the chemotherapeutic agent and/or hormone therapeutic agent are administered alone or in combination with other chemotherapeutic agents. Variation in dosage will likely occur depending on the condition being treated. As described above, in some embodiments, the chemotherapeutic agents and/or hormone therapeutic agents may be administered at a reduced level.
The dose of the rapamycin or its derivative therein in the nanoparticle composition will vary with the nature of the combination therapy and the particular disease being treated. In some embodiments, the amount of rapamycin or a derivative thereof in the nanoparticle composition in the combination therapy is included in any of the following ranges: about 0.5 to about 5 mg, about 5 to about 10 mg, about 10 to about 15 mg, about 15 to about 20 mg, about 20 to about 25 mg, about 20 to about 50 mg, about 25 to about 50 mg, about 50 to about 75 mg, about 50 to about 100 mg, about 75 to about 100 mg, about 100 to about 125 mg, about 125 to about 150 mg, about 150 to about 175 mg, about 175 to about 200 mg, about 200 to about 225 mg, about 225 to about 250 mg, about 250 to about 300 mg, about 300 to about 350 mg, about 350 to about 400 mg, about 400 to about 450 mg, or about 450 to about 500 mg. In some embodiments, the amount of rapamycin or derivative thereof in the effective amount of the nanoparticle composition (e.g., a unit dosage form) for combination therapy is in the range of about 54 mg to about 540 mg, such as about 180 mg to about 270 mg or about 216 mg.

Suitable radioactive isotopes include, but are not limited to, astatine211, carbon14, chromium51, chlorine36, iron57, cobalt58, copper67, Eu152, gallium67, hydrogen3, iodine123, iodine131, indium111, iron59, phosphorus32, rhenium186, selenium75, sulphur35, technicium99m, and/or yttrium90.
In some embodiments, enough radiation is applied to the individual so as to allow reduction of the normal dose of the rapamycin or a derivative thereof in the nanoparticle composition required to affect 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 rapamycin or derivative thereof in the nanoparticle composition is administered so as to allow reduction of the normal dose of the radiation required to affect 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 rapamycin or a derivative thereof in the nanoparticle composition and the radiation are reduced as compared to the corresponding normal dose of each when used alone.
In some embodiments, the combination of administration of the rapamycin or a derivative thereof nanoparticle composition and the radiation therapy produce supra-additive effect. In some embodiments, the rapamycin or a derivative thereof in the nanoparticle composition is administered once at the dose of about 50 mg to 540 mg or about 30 mg/m2 to 300 mg/m2, and the radiation is applied five times at 80 Gy daily.
Administration of rapamycin or a derivative thereof nanoparticle compositions disclosed above in conjunction with administration of chemotherapeutic agent and/or hormone therapeutic agent is equally applicable to those in conjunction with radiation therapy and/or surgery.

Pharmaceutical AgentsProvided herein are compositions comprising nanoparticles that comprise rapamycin for use in the methods of treatment of cancer, methods of administration, and dosing regimes described herein. In some embodiments, rapamycin may be rapamycin or its derivatives or pharmaceutically acceptable salts and accordingly the invention contemplates and includes all these embodiments. Rapamycin is sometimes referred to elsewhere as sirolimus, rapammune, or rapamune. Derivatives of rapamycin include, but are not limited to, compounds that are structurally similar to rapamycin or are in the same general chemical class as rapamycin.
In some embodiments, the derivative of rapamycin retains one or more similar biological, pharmacological, chemical and/or physical properties (including, for example, functionality) as rapamycin. In some embodiments, the rapamycin derivative has at least about any of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95% or 100% of an activity of rapamycin. For example, the decrease in the size of a tumor, the number of cancer cells, or the growth rate of a tumor caused by a rapamycin derivative is preferably at least about any of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95% or 100% of the corresponding decrease caused by the same amount of rapamycin. An exemplary rapamycin derivative includes benzoyl rapamycin, such as that disclosed in paragraph [0022] of WO 2006/089207, which is hereby incorporated by reference in its entirety. Other exemplary rapamycin derivatives include WY-090217, AY-22989, NSC-226080, SiiA-9268A, oxaazacyclohentriacontine, temsirolimus (CCI-779 (Wyeth)), everolimus (RAD001 (Novartis)), pimecrolimus (ASM981), SDZ-RAD, SAR943, ABT-578, AP23573, and Biolimus A9.
Carrier ProteinsProvide herein are compositions comprising nanoparticles that comprise rapamycin and a carrier protein for use methods of treatment of cancer, methods of administration, and dosage regimes described herein. In some embodiments, rapamycin may be rapamycin or its derivatives or pharmaceutically acceptable salts and accordingly the invention contemplates and includes all these embodiments. In some embodiments, the carrier protein is albumin. In some embodiments, the carrier protein is human serum albumin.
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, α-acid glycoprotein, β-2-macroglobulin, thyroglobulin, transferin, fibronectin, factor VII, factor VIII, factor IX, factor X, and the like. In some embodiments, the carrier protein is a non-blood protein, such as casein, α-lactalbumin, or β-lactoglobulin. The carrier proteins may either be natural in origin or synthetically prepared. In some embodiments, the pharmaceutical acceptable carrier comprises albumin, such as human serum albumin (HSA). HSA is a highly soluble globular protein of Mr 65 K 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). 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 animals (including domestic pets and agricultural animals).
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 drugs, 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 (1981), 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 (1992), and Carter et al., Adv. Protein. Chem., 45, 153-203 (1994)).
The carrier protein (e.g., albumin) in the composition generally serves as a carrier for rapamycin or derivative thereof, i.e., the carrier protein in the composition makes the rapamycin or derivative thereof 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 for solubilizing rapamycin or a derivative thereof, and thereby can reduce one or more side effects of administration of rapamycin or a derivative thereof into an individual (e.g., human). In some embodiments, the composition is substantially free (e.g. free) of organic solvents or surfactants. A composition is “substantially free of organic solvent” or “substantially free of surfactant” if the amount of organic solvent or surfactant in the composition is not sufficient to cause one or more side effect(s) in an individual when the composition is administered to the individual.
Rapamycin is “stabilized” in an aqueous suspension if it remains suspended in an aqueous medium (e.g., 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 (e.g., human). Stability of the suspension is generally (but not necessarily) evaluated at storage temperature, such as room temperature (e.g., 20-25° C.) or refrigerated conditions (e.g., 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.
In some embodiments, the composition comprises nanoparticles comprising (in various embodiments consisting essentially of) rapamycin and a carrier protein. When rapamycin is in a liquid form, the particles or nanoparticles are also referred to as droplets or nanodroplets. In some embodiments, rapamycin is coated with the carrier protein. Particles (such as nanoparticles) of poorly water soluble pharmaceutical agents have been disclosed in, for example, U.S. Pat. Nos. 5,916,596; 6,506,405; and 6,537,579 and also in U.S. Pat. App. Pub. No. 2005/0004002A1.
The amount of carrier protein in the composition described herein will vary depending on the rapamycin or derivative thereof and other components in the composition. In some embodiments, the composition comprises a carrier protein in an amount that is sufficient to stabilize the rapamycin in an aqueous suspension, for example, in the form of a stable colloidal suspension (e.g., a stable suspension of nanoparticles). In some embodiments, the carrier protein is in an amount that reduces the sedimentation rate of rapamycin in an aqueous medium. For particle-containing compositions, the amount of the carrier protein also depends on the size and density of particles of rapamycin.
In some embodiments of any of the aspects of the invention, the rapamycin or a derivative thereof is coated with a carrier protein, such as albumin (e.g., human serum albumin). In various embodiments, the composition comprises more than about any of 50%, 60%, 70%, 80%, 90%, 95%, or 99% of the rapamycin or derivative thereof in nanoparticle form. In some embodiments, the rapamycin or derivative thereof constitutes more than about any of 50%, 60%, 70%, 80%, 90%, 95%, or 99% of the nanoparticles by weight. In some embodiments, the nanoparticle has a non-polymeric matrix. In some embodiments, the rapamycin or derivative thereof is in an anhydrous, amorphous, and/or non-crystalline form. In some embodiments, the rapamycin or derivative thereof is amorphous. In some embodiments, the nanoparticles comprise a core of rapamucin or derivative thereof that is substantially free of polymeric materials (such as polymeric matrix).
In some embodiments, the albumin to rapamycin weight ratio in the nanoparticles or in the nanoparticle composition 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, 7.5:1 or less, 7:1 or less, 6:1 or less, 5:1 or less, 4:1 or less, or 3:1 or less. In some embodiments, the composition comprises a stable aqueous suspension of particles (e.g., nanoparticles) comprising rapamycin or a derivative thereof and albumin (e.g., particles of rapamycin or a derivative thereof coated with albumin).
In some embodiments, the composition comprises nanoparticles of any shape (e.g., a spherical or non-spherical shape) with an average or mean diameter of no greater than about 1000 nanometers (nm), such as no greater than about any of 900 run, 800 nm, 700 nm, 600 nm, 500 nm, 400 run, 300 run, 200 nm, or 100 nm.

Methods of Making the CompositionsMethods of making compositions containing carrier proteins and poorly water soluble pharmaceutical agents are known in the art. For example, nanoparticles containing poorly water soluble pharmaceutical agents and carrier proteins (e.g., 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; and 6,537,579 and also in U.S. Pat. Pub. No. 2005/0004002A1, which are each hereby incorporated by reference in their entireties.
Briefly, the rapamycin or derivative hereof is dissolved in an organic solvent. Suitable organic solvents include, for example, ketones, esters, ethers, chlorinated solvents, and other solvents known in the art. For example, the organic solvent can be methylene chloride, chloroform/ethanol, or chloroform/t-butanol (for example with a ratio of about any 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 or with a ratio of about any of 3:7, 5:7, 4:6, 5:5, 6:5, 8:5, 9:5, 9.5:5, 5:3, 7:3, 6:4, or 9.5:0.5). The solution is added to a carrier protein (e.g., human serum albumin). The mixture is subjected to high pressure homogenization (e.g., using an Avestin, APV Gaulin, Microfluidizer™ such as a Microfluidizer™ Processor M-110EH from Microfluidics, Stansted, or Ultra Turrax homogenizer). The emulsion may be cycled through the high pressure homogenizer for between about 2 to about 100 cycles, such as about 5 to about 50 cycles or about 8 to about 20 cycles (e.g., about any of 8, 10, 12, 14, 16, 18 or 20 cycles). The organic solvent can then be removed by evaporation utilizing suitable equipment known for this purpose, including, but not limited to, rotary evaporators, falling film evaporators, wiped film evaporators, spray driers, and the like that can be operated in batch mode or in continuous operation. The solvent may be removed at reduced pressure (such as at about any of 25 mm Hg, 30 mm Hg, 40 mm Hg, 50 mm Hg, 100 mm Hg, 200 mm Hg, or 300 mm Hg). The amount of time used to remove the solvent under reduced pressure may be adjusted based on the volume of the formulation. For example, for a formulation produced on a 300 mL scale, the solvent can be removed at about 1 to about 300 mm Hg (e.g., about any of 5-100 mm Hg, 10-50 mm Hg, 20-40 mm Hg, or 25 mm Hg) for about 5 to about 60 minutes (e.g., about any of 7, 8, 9, 10, 11, 12, 13, 14, 15 16, 18, 20, 25, or 30 minutes).
If desired, human albumin solution may be added to the dispersion to adjust the human serum albumin to rapamycin ratio or to adjust the concentration of rapamycin in the dispersion. For example, human serum albumin solution (e.g., 25% w/v) can be added to adjust the human serum albumin to rapamycin ratio to about any of 18:1, 15:1 14:1, 13:1, 12:1, 11:1, 10:1, 9:1, 8:1, 7.5:1, 7:1, 6:1, 5:1, 4:1, or 3:1. For example, human serum albumin solution (e.g., 25% w/v) or another solution is added to adjust the concentration of rapamycin in the dispersion to about any of 0.5 mg/ml, 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, or 50 mg/ml. The dispersion may be serially filtered through multiple filters, such as a combination of 1.2 μm and 0.8/0.2 μm filters; the combination of 1.2 μm, 0.8 μm, 0.45 μm, and 0.22 μm filters; or the combination of any other filters known in the art. The dispersion obtained can be further lyophilized. The nanoparticle compositions may be made using a batch process or a continuous process (e.g., the production of a composition on a large scale).
If desired, a second therapy (e.g., one or more compounds useful for treating breast cancer), an antimicrobial agent, sugar, and/or stabilizing agent can also be included in the composition. This additional agent can either be admixed with the rapamycin and/or the carrier protein during preparation of the rapamycin/carrier protein composition, or added after the rapamycin/carrier protein composition is prepared. For example, the agent can be added along with an aqueous medium used to reconstitute/suspend the rapamycin/carrier protein composition or added to an aqueous suspension of the carrier protein-associated rapamycin. In some embodiments, the agent is admixed with the rapamycin/carrier protein composition prior to lyophilization. In some embodiments, the agent is added to the lyophilized pharmaceutical agent/carrier protein composition. In some embodiments when the addition of the agent changes the pH of the composition, the pH in the composition are generally (but not necessarily) adjusted to a desired pH. Exemplary pH values of the compositions include, for example, in the range of about 5 to about 8.5. In some embodiments, the pH of the composition is adjusted to no less than about 6, including for example no less than any of about 6.5, 7, or 8 (e.g., about 8).
The invention also provides methods of making the combination therapies described herein for use in the treatment of cancer. For example, there is provided a method of preparing a composition comprising rapamycin or a derivative thereof, a carrier protein (e.g., albumin), and a second therapy by combining (e.g., admixing) a composition containing rapamycin (or a derivative thereof) and a carrier protein with a second therapy (e.g., one or more other pharmaceutically active agents for the treatment of cancer). If desired, an antimicrobial agent, sugar, and/or stabilizing agent can also be included in the composition.

Example 1: Exemplary Methods for the Formation of Nanoparticle Compositions with Rapamycin and Albumin Example 1-AThis example demonstrates the preparation of a pharmaceutical composition comprising rapamycin and albumin in which the rapamycin concentration was 8 mg/mL in the emulsion and the formulation was made on a 300 mL scale. Rapamycin (2400 mg) was dissolved in 12 mL of chloroform/t-butanol. The solution was then added into 288 mL of a human serum albumin solution (3% w/v). The mixture was homogenized for 5 minutes at 10,000 rpm (Vitris homogenizer model Tempest I.Q.) in order to form a crude emulsion, and then transferred into a high pressure homogenizer. The emulsification was performed at 20,000 psi while recycling the emulsion. The resulting system was transferred into a Rotavap, and the solvent was rapidly removed at 40° C. at reduced pressure (25 mm of Hg). The resulting dispersion was translucent. At this stage, human serum albumin solution was added to the dispersion to adjust the human serum albumin to rapamycin ratio. The dispersion was serially filtered through multiple filters. The size of the filtered formulation was 85-100 nm (Zav, Malvern Zetasizer). The dispersion was further lyophilized (FTS Systems, Dura-Dry μP, Stone Ridge, N.Y.) for 60 hours. The resulting cake was easily reconstitutable to the original dispersion by the addition of sterile water or 0.9% (w/v) sterile saline. The particle size after reconstitution was the same as before lyophilization.
Example 1-BThis example demonstrates the preparation of a pharmaceutical composition comprising rapamycin and albumin in which the rapamycin concentration was 8.3 mg/mL in the emulsion and the formulation was made on a 200 mL scale. Rapamycin (1660 mg) was dissolved in 8.5 mL of chloroform/ethanol. The solution was then added into 191.5 mL of a human serum albumin solution (6% w/v). The mixture was homogenized for 5 minutes at 10,000 rpm (Vitris homogenizer model Tempest I.Q.) in order to form a crude emulsion, and then transferred into a high pressure homogenizer. The emulsification was performed at 20,000 psi while recycling the emulsion. The resulting system was transferred into a Rotavap, and the solvent was rapidly removed at 40° C. at reduced pressure (25 mm of Hg). The dispersion was serially filtered. The size of the 0.22 μm filtered formulation was 85 nm (Zav, Malvern Zetasizer). The dispersion was further lyophilized (FTS Systems, Dura-Dry μP, Stone Ridge, N.Y.) for 60 hours.

Example 4: Use of Human Clinical Trials to Determine the Ability of Compositions of the Invention to Treat, Stabilize, Prevent, and/or Delay CancerIf desired, any of the compositions described herein can also be tested in humans to determine the ability of the compositions to treat, stabilize, prevent and/or delay cancer (e.g., breast cancer). Standard methods can be used for these clinical trials.
In one exemplary method, subjects (e.g., healthy subjects, subjects with cancer such as breast cancer, or subjects at increased risk for cancer such as breast cancer) are enrolled in a tolerability, pharmacokinetics, and pharmacodynamics phase I study of Nab-rapamycin or a derivative thereof using standard protocols. For example, escalating doses of rapamycin or a derivative thereof up to about 250 mg/m2 as part of a composition of the invention can be tested. Then a phase II, double-blind randomized controlled trial is performed to determine the efficacy of the Nab-rapamycin or a derivative thereof. If desired, the activity of Nab-rapamycin or a derivative thereof can be compared to that of another treatment for cancer (e.g., breast cancer). Alternatively or additionally, the efficacy of a combination of Nab-rapamycin or a derivative thereof and another treatment for cancer (e.g., breast cancer) can be compared to that of either treatment alone.
Example 5: Multiple Myeloma (MM) Cell Lines for Use in Determination of Nab-Rapamycin ActivityInterleukin-6 (IL-6) and insulin like growth factor-1 (IGF-1) play a key role in the growth, survival, and drug resistance in multiple myeloma (MM) cells. Furthermore, their secretion in bone marrow stromal cells (BMSCs) is up-regulated by adherence of MM cells. IL-6 and IGF-1 mediate growth of MM cells via activation of the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3′-kinase/Akt kinase (PI3-K/Akt) signaling cascades. Several studies show that PI3-K/Akt signaling mediates growth, survival, migration and cell cycle regulation in MM. Activated Akt in turn phosphorylates downstream target molecules, including forkhead transcription factor (FKHR), glycogen synthase kinase (GSK)-3β, and mammalian target of rapamycin (mTOR).
MM cell lines can be used in standard cell-based assays to test the ability of any of the nanoparticle compositions of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) to treat MM. The nanoparticle compositions of the invention are desirable because they may allow rapamycin to be delivered at higher doses with improved efficacy.
For these cell-based assays, RPMI 8226 and U266 human MM cell lines are obtained from the American Type Culture Collection (ATCC) of Rockville, Md. Patient derived MM cells are purified from patient BM samples, as described by Y. T. Tai, G. Teoh, Y. Shima, et al., J. Immunol. Methods 235:11, 2000. Human MM cell lines are cultured in RPMI-1640 media (Sigma Chemical, St. Louis, Mo.), containing 10% fetal bovine serum (FBS), 2 nunol/L L-glutamine (L-glut, GIBCO, Grand Island, N.Y.), 100 U/mL penicillin and 100 mg/mL streptomycin (P/S, GIBCO). MM patient cells are 95% CD38+, CD45RA−. Bone marrow stromal cells (BMSCs) are prepared from aspirates of MM patients as well as healthy donors as described by D. Gupta, S. Treon, Y. Shima, et al. in Leukemia, 2001 and S. Gartner and H. S. Kaplan in Proc. Nag. Acad. Sci. USA 77:4756, 1980. Cells are cultured in ISCOVE's modified Dulbecco media containing 20% FBS, 2 mmol/L L-glut, and 100 μg/mL P/S. Human umbilical vein endothelial cells (HUVEC P168) are purchased from Clonetics, Biowhittaker, and maintained in EGM-2MV media (Clonetics, Biowhittaker). The nanoparticles comprising rapamycin and a carrier protein (such as albumin) are diluted in culture medium to concentrations ranging, e.g., from 0.01 to 100 μM.
Example 6: Panel of Drug-Resistant MM Cell Lines and Primary MM Tumor Cells for Use in Determination of Nab-Rapamycin ActivityEffectiveness of the nanoparticle compositions of the invention may further be evaluated in drug resistant cell lines. The use of drug resistant cells facilitates the determination of potential cancer patient subpopulations that may be effectively treated by the use of the nanoparticle compositions of the invention. The activity of any of the nanoparticle compositions of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) can be evaluated in a panel of drug-sensitive and drug-resistant human MM cell lines using standard methods. Exemplary cell lines include a dexamethasone (Dex)-sensitive MM-1S cell line, a Dex-resistant MM-1R cell line; the chemo-sensitive parental MM cell line RPMI-8226/S, and its chemo-resistant sublines RPMI-8226/Dox40 (doxorubicin-resistant), RPMI-8226/MR20 (mitoxantrone-resistant), and RPMI-8226/LR5 (melphalan-resistant) cells; MM-1S-TR15 is a TRAIL/Apo2L-resistant subline; MM-SAR-1 (also referred to as MM-SA-1) cells that are primary MM tumor cells from a patient resistant to the proteasome inhibitor bortezomib (PS-341) (cells maintained in vitro resistance to PS-341); OCI-My-5 cells; S6B45 cells; ARD; ARK; ARP-1; OPM-1; OPM-6; K620; LP-1; U266; and NCI-H929 cells. All cells are cultured in RPMI 1640 medium (Life Technologies, Grand Island, N.Y.) supplemented with 10% fetal bovine serum, L-glutamine, penicillin, and streptomycin (Life Technologies).
Primary MM tumor cells additionally may be isolated from bone marrow (BM) aspirates of patients, who are resistant to conventional (steroid- and cytotoxic chemotherapy-based) and more recently developed anti-MM agents (e.g. thalidomide or proteasome inhibitors). The resistant primary MM tumor cells are collected from patients as described above in Example 4.
Example 7: Co-Culture Assays of MM Cells with Bone Marrow Stromal Cells (BMSCs) Treated with Nab-RapamycinWhen adhering to BMSCs, MM cells have reduced sensitivity to conventional anti-MM therapies, such as dexamethasone or cytotoxic chemotherapeutics (Chauhan D. et al., Blood 1996, 87, 1104-1112). This form of drug resistance is considered a key reason why MM patients eventually relapse when they receive treatment based on administration of glucocorticoids and/or cytotoxic chemotherapy. Therefore, any of the nanoparticle compositions of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) can be tested to determine whether they overcome the molecular sequelae of the interaction of BMSCs with MM cells and achieve anti-MM activity in this context. In particular, an in vitro co-culture assay is performed using MM cells with BMSCs as previously described. BMSCs are grown on 24-well plates to confluency. Following washings with serum-free medium, primary tumor cells (greater than about 95% purity in CD138+ cells) isolated from MM patients are added to BMSC-coated or control wells as described previously (Uchiyama H. et al., Blood 1993, 82, 3712-3720; Mitsiades N. et al., Blood 2003, 101, 4055-4062) and incubated for 48 hours in the presence or absence of a nanoparticle composition of the invention, such as nab-rapamycin. Flow cytometric analysis is performed to detect the CD138+ population of viable MM cells and the effect of the nanoparticle composition on MM cell viability is expressed as a percent of viable cells in comparison to the respective vehicle-treated cultures.
Example 8: MTT Calorimetric Survival Assay of MM Tissue Culture Cells Treated with Nab-RapamycinIn this example, the effect of nanoparticle composition of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) on cell viability and survival is assessed. Cell survival is examined using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT; Sigma Chemical, St Louis, Mo.) colorimetric assay, as previously described (Mitsiades C. S. et al., Blood 2001, 98, 795-804; Mitsiades N. et al., PNAS 2002, 99, 14374-14379; Mitsiades N. et al., Blood 2003, 101, 2377-2380). Briefly, cells are plated in 48-well plates at 70% to 80% confluence in the presence of 2.5% fetal bovine serum (FBS) and in the presence of a nanoparticle composition of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) at final concentration of 0-100 nM rapamycin or DMSO vehicle control. At the end of each treatment, cells are incubated with 1 mg/mL MTT for 4 hours at 37° C. A mixture of isopropanol and 1 N HCl (23:2, vol/vol) is then added under vigorous pipetting to dissolve the formazan crystals. Dye absorbance (A) in viable cells is measured at 570 nm, with 630 nm as a reference wavelength. Cell viability is estimated as a percentage of the value of untreated controls. Experiments are typically repeated at least 3 times, and each experimental condition is typically repeated at least in triplicate wells in each experiment. Data is reported are average values+/−SD of representative experiments.
Example 9: Proliferation of MM Cells Treated with Nab-RapamycinIn this example, the effect of nanoparticle composition of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) on cell proliferation and viability is assessed. For proliferation and cell viability assays, MM cells are first starved for 12 hours in RPMI-1640 media containing 10% fetal bovine serum, and then plated into 96-well microtiter plates (Costar, Cambridge, Mass.), in the presence of a nanoparticle composition of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) or DMSO control. Proliferation is measured by the incorporation of 3H-thymidine (NEN Products, Boston, Mass.). Specifically, cells are pulsed with 3H-thymidine (0.5 .muck/well) for the last 6 hours of 48 hour cultures, harvested onto glass filters with an automatic cell harvester (Cambridge Technology, Cambridge, Mass.), and counted using a LKB Betaplate scintillation counter (Wallac, Gaithersburg, Md.). Measurement of cell viability is performed colorimetrically using a MTS assay, utilizing the CellTiter96 One Solution Reagent (Promega, Madison, Wis.). Cells are exposed to the MTS for the last 2 hours of 48 hour cultures, and absorbance is measured using an ELISA plate reader (Molecular Devices Corp., Sunnyvale, Calif.) at OD of 570 nm.

MM cells (1×106 cells) are cultured in the presence of a nanoparticle composition of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) or DMSO control for 24, 48 and 72 hours. Cells are then washed with phosphate buffered saline (PBS), fixed with 70% ethanol, and treated with RNAse (Sigma). Cells are next stained with propidium iodide (PI, 5 μg/mL), and the cell cycle profile is determined using the M software on an Epics flow cytometer (Coulter Immunology, Hialeah, Fla.).
Example 11: Other MM Cell Activity Assays for Cells Treated with Nab-RapamycinNanoparticle composition of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) can be further assessed by other activity assays known in the art. For example, the molecular mechanisms of anti-MM activities of nanoparticle composition of the invention may be assessed using, but not limited to, cell cycle profiling by caspases/PARP cleavage and quantification of anti-apoptotic proteins by Western blotting.

Mice are inoculated subcutaneously into the right flank with 3×107 MM cells in 100 mL of RPMI 1640, together with 100 μL matrigel basement membrane matrix (Becton Dickinson, Bedford, Mass.). On day 6 post injection, mice are assigned into two treatment groups receiving a nanoparticle composition of the invention (e.g., nanoparticles comprising rapamycin and a carrier protein such as albumin) or into a control group. Treatment with a nanoparticle composition of the invention is then intravenously administered either saline or nanoparticles comprising rapamycin and a carrier protein such as albumin at a dose level of 40 mg/kg with a three times weekly schedule for 4 weeks. The dosing volume is 2 ml/kg. Caliper measurements of the longest perpendicular tumor diameters are performed twice per week to estimate the tumor volume. Animals are sacrificed when their tumor reached 2 cm or when the mice become moribund. Survival is evaluated from the first day of tumor injection until death.
Example 12B: Effect of Nab-Rapamycin on Human MM1S Cells In VivoIn this example, the effect of Nab-rapamycin on MM I S cell growth in vivo was assessed. Mice were inoculated subcutaneously into the right flank with 3×107 MM1S cells in 100 mL of RPMI 1640, together with 100 μL matrigel basement membrane matrix (Becton Dickinson, Bedford, Mass.). On day 6 post injection, mice were assigned into three treatment groups receiving Nab-rapamycin or into a control group. Animals in the control group were administered with 0.9% NaCl solution (i.v.). Animals in the three treatment groups were administered with Nab-rapamycin at a dose schedule of 20 or 40 mg/kg three times weekly or at a dose schedule of 30 mg/kg daily for 15 days. The dosing volume was 2 ml/kg. Caliper measurements of the longest perpendicular tumor diameters were performed twice per week to estimate the tumor volume. Animals were sacrificed when their tumor reached 2 cm or when the mice became moribund. As shown in
The following example is disclosed in U.S. Ser. No. 11/359,286, which was filed Feb. 21, 2006 (i.e., U.S. Pat. Pub. No. 2006/0263434, published Nov. 23, 2006). Nude mice were implanted with 106 HT29 cells on their right flanks. Treatment was initiated once the tumors were palpable and were greater than 100-200 mm3. The mice were randomly sorted into 4 groups (n=8 per group). Group 1 received saline 3 times weekly for 4 weeks, i.v.; Group 2 received Abraxane™ at 10 mg/kg, daily for 5 days, i.p.; Group 3 received Nab-rapamycin at 40 mg/kg, 3 times weekly for 4 weeks, i.v.; and Group 4 received both Nab-rapamycin (40 mg/kg, 3 times weekly for 4 weeks, i.v.) and Abraxane™ (10 mg/kg, daily for 5 days, i.p.). As shown in
The antitumor activity of Nab-rapamycin was examined using HT29 human colon carcinoma xenograft in mice. Male athymic mice (3 per group) were implanted with 106 HT29 cells on their right flanks and allowed to grow to ˜100 mm3. The mice were then intravenously administered with either DMSO at 2 mL/kg or Nab-rapamycin at a dose level of 40 mg/kg with a three times weekly schedule for 4 weeks at a dosing volume of 5 mL/kg. Tumor growth data were analyzed by ANOVA.
Nab-rapamycin significantly inhibited in vivo tumor growth for HT29 tumors, achieving a tumor growth inhibition of 78.9% against the HT29 tumor xenograft (p=0.005 versus control, ANOVA;
The antitumor activity of Nab-rapamycin was examined using HCT-116 human colon carcinoma xenograft in mice. HCT-116 tumors were implanted subcutaneously into the right flanks of male athymic nude mice (10 per group) and allowed to grow to 100-221 mm3. The mice were then intravenously administered with either saline or Nab-rapamycin at a dose level of 40 mg/kg with a three times weekly schedule for 4 weeks at a dosing volume of 10 mL/kg. Tumor growth data were analyzed by ANOVA.
Nab-rapamycin significantly inhibited in vivo tumor growth for HCT-116 tumors, achieving a tumor growth inhibition of 71% against the HCT-116 tumor xenograft (p<0.0001 versus control, ANOVA;
