METHODS OF USING CARFILZOMIBCROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of priority to U.S. Provisional Patent Application No. 63 / 518,343, filed August 9, 2023, which is hereby incorporated by reference in its entirety.BACKGROUND

[0002] Carfilzomib is a proteasomal inhibitor that is currently marketed as KYPROLIS® and is approved in many countries for the treatment of relapsed and / or refractory multiple myeloma (RRMM). In Europe and the US, carfilzomib is approved for use in combination with dexamethasone (Kd), with lenalidomide and dexamethasone (KRd), with daratumumab and dexamethasone (KdD), as well as with isatuximab and dexamethasone (Isa-Kd). Carfilzomib as a single agent is also indicated to treat patients with RRMM in the US. The current route of administration for KYPROLIS® is IV (intravenous) and dosing is based on the body surface area of the patient. The final concentration of reconstituted carfilzomib solution prior to addition into intravenous bags is 2 mg / mL.SUMMARY

[0003] In some cases, a twice weekly (twice-a-week) intravenous administration may be inconvenient for the patient and present challenges when contemplating administering carfilzomib in combination with other therapies for multiple myeloma. Moreover, there is a known toxicity profile associated with carfilzomib that must be considered in the risk / benefit profile for multiple myeloma patients. Accordingly, once weekly (once-a-week) carfilzomib dosing regimens and methods to lower the toxicity associated with carfilzomib would be useful. In view of the foregoing, it may be useful to have safe and convenient alternative methods for treating a disease or condition (e.g., multiple myeloma) comprising administering carfilzomib or a pharmaceutically acceptable salt thereof.

[0004] Provided herein are methods for treating multiple myeloma in a patient, comprising administering to the patient a pharmaceutical composition comprising carfilzomib or a pharmaceutically acceptable salt thereof and an aqueous carrier, wherein the carfilzomib is administered at a dose volume of 2.5 mL / kg or higher.

[0005] Also provided herein are methods for treating multiple myeloma in a patient, comprising administering to the patient a pharmaceutical composition comprising carfilzomib or a pharmaceutically acceptable salt thereof and an aqueous carrier, wherein the carfilzomib is administered at a concentration of less than 2 mg / mL.

[0006] Also provided herein are methods for treating a disease or condition selected from the group consisting of cancer, autoimmune disease, graft or transplant-related condition, neurodegenerative disease, fibrotic- associated condition, ischemic-related conditions, infection (viral, parasitic or prokaryotic) and diseases associated with bone loss, the method comprising administering to a patient a therapeutically effective amount of carfilzomib or a pharmaceutically acceptable salt thereof at a dose volume of 10 mL / kg or higher.

[0007] Also provided herein are methods for treating a patient suffering from a disease or condition selected from the group consisting of cancer, autoimmune disease, graft or transplant-related condition,neurodegenerative disease, fibrotic-associated condition, ischemic-related conditions, infection (viral, parasitic or prokaryotic) and diseases associated with bone loss, the method comprising administering to the patient a therapeutically effective amount of carfilzomi b or a pharmaceutically acceptable salt thereof at a concentration of less than 2 mg / mL.BRIEF DESCRIPTION OF THE FIGURES

[0063] The present disclosure provides methods for treating a disease or condition comprising administering to a patient carfilzomib or a pharmaceutically acceptable salt thereof. As used herein, the terms "treat", "treating", and "treatment" as used herein refer to therapy, including without limitation, curative therapy, prophylactic therapy, and preventative therapy and generally include reversing, reducing, or arresting the symptoms, clinical signs, and underlying pathology of a condition in manner to improve or stabilize a patient's condition.Prophylactic treatment generally constitutes either preventing the onset of disorders altogether or delaying the onset of a pre-cl inically evident stage of disorders in individuals. The term "prophylactic or therapeutic" treatment is art- recognized and includes administration to the host of one or more of the subject compositions. If it is administered prior to clinical manifestation of the unwanted condition (e.g., disease or other unwanted state of the host animal), or after the condition has subsided, then the treatment is prophylactic (i.e., it protects the host against developing the unwanted condition), whereas if it is administered after manifestation of the unwanted condition, the treatment is therapeutic, (i.e., it is intended to diminish, ameliorate, or stabilize the existing unwanted condition or side effects thereof).

[0064] As used herein, the term "patient" as used herein refers to any mammal, including humans, and animals such as cows, horses, dogs and cats. Thus, the invention may be used in human patients as well as in veterinarian subjects and patients. In some embodiments, carfilzomib or a pharmaceutically acceptable salt thereof is administered to a human patient.

[0065] As used herein, the phrase "therapeutical ly-effective" or "therapeutically effective amount" is intended to quantify the amount of a compound (e.g., carfilzomib or a pharmaceutically acceptable salt thereof), which when administered as part of a desired dosage regimen (to a patient, e.g., a human) alleviates a symptom, ameliorates a condition, or slows the onset of disease conditions according to clinically acceptable standards for the disorder or condition to be treated or the cosmetic purpose, for example, at a reasonable benefit / risk ratio applicable to any medical treatment. Thus, it is the amount of a compound (e.g., carfilzomib or a pharmaceutically acceptable salt thereof) that can treat cancer, whether it is multiple myeloma or other hematologic malignancy or a solid tumor.

[0066] In some embodiments, the disclosure provides a method for treating a disease or condition selected from the group consisting of cancer, autoimmune disease, graft or transplant-related condition, neurodegenerative disease, fibrotic-associated condition, ischemic-related conditions, infection (viral, parasitic or prokaryotic) and diseases associated with bone loss, the method comprising administering to a patient a therapeutically effective amount of carfilzomib or a pharmaceutically acceptable salt thereof at a dose volume of 10 mL / kg or higher.

[0067] In some embodiments, the disclosure provides a method for treating a disease or condition selected from the group consisting of cancer, autoimmune disease, graft or transplant-related condition, neurodegenerative disease, fibrotic-associated condition, ischemic-related conditions, infection (viral, parasitic or prokaryotic) and diseases associated with bone loss, the method comprising administering to a patient a therapeutically effective amount of carfilzomi b or a pharmaceutically acceptable salt thereof at a concentration of less than 2 mg / mL.

[0068] In some embodiments, in conjunction with other embodiments, the disease or condition is cancer. As used herein, the terms "cancer" and "cancerous" when used herein refer to or describe the physiological condition in subjects that is typically characterized by unregulated cell growth. Examples of cancer include, without limitation, hematologic malignancies or blood borne cancers such as multiple myeloma and leukemia, and other cancers such as carcinoma, lymphoma, sarcoma, and blastoma. More particular examples of such cancers include squamous cell carcinoma, lung cancer, pancreatic cancer, cervical cancer, bladder cancer, hepatoma, breast cancer, colon carcinoma, and head and neck cancer. While the term "cancer" as used herein is not limited to any one specific form of the disease, it is believed that the methods of the invention will be particularly effective for cancers, in a subject, which have become resistant in some degree to treatment with anti-cancer agents, including without limitation chemotherapeutic agents, antimitotic agents, anthracyclines and the like, and for cancers which have relapsed post treatment with such anti-cancer agents. In some embodiments, the cancer is multiple myeloma (e.g., relapsed and / or refractory multiple myeloma or newly diagnosed multiple myeloma). In some embodiments, the multiple myeloma is relapsed and / or refractory multiple myeloma. In some embodiments, the multiple myeloma is newly diagnosed multiple myeloma.

[0069] In some embodiments, the disclosure provides a method for treating multiple myeloma in a patient, comprising administering to the patient a pharmaceutical composition comprising carfilzomib or a pharmaceutically acceptable salt thereof and an aqueous carrier, wherein the carfilzomib is administered at a dose volume of 2.5 mL / kg or higher.

[0070] In some embodiments, the disclosure provides a method for treating multiple myeloma in a patient, comprising administering to the patient a pharmaceutical composition comprising carfilzomib or a pharmaceutically acceptable salt thereof and an aqueous carrier, wherein the carfilzomib is administered at a concentration of less than 2 mg / mL.Dosing

[0071] The disclosed methods comprise administering carfilzomib or a pharmaceutically acceptable salt thereof, e.g., in a pharmaceutical composition, at a particular dose and / or dose volume. Applicant has surprisingly discovered that for a given dose of carfilzomib, a greater proteasomal inhibition activity from carfilzomib is provided by increasing the volume (i.e., increasing the dose volume). Moreover, Applicant has surprisingly discovered that a desired proteasomal inhibition response can be achieved by lowering the total dose amount of carfilzomib, for example, by decreasing the carfilzomib concentration and increasing its volume of administration. The disclosed methods provide several advantages over certain conventional administration,including but not limited to, lowering the toxicity profile of carfilzomib and providing once-weekly (once-per-week) intravenous dosing for carfilzomib.

[0072] The dose of carfilzomib can be calculated using body surface area (BSA). The BSA can be calculated using any suitable method. In some embodiments, carfilzomib is administered at a dose selected from 10 to 100 mg / m2body surface area (e.g., 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100 mg / m2body surface area). In some embodiments, in conjunction with other embodiments, carfilzomib is administered at a dose of 15, 20, 27, 36, 45, 56, or 70 mg / m2body surface area. In some embodiments, in conjunction with other embodiments, carfilzomib is administered at a dose of 27, 56, or 70 mg / m2body surface area.Dose Volume

[0086] The following examples further illustrate the disclosed methods, but of course, should not be construed as in any way limiting its scope.EXAMPLE 1

[0087] This example demonstrates embodiments of the disclosed methods comprising administering carfilzomib subcutaneously with and without hyaluronidase.1.1 Carfilzomib Formulation

[0088] Carfilzomib was weighed into appropriately sized reaction vessels (e.g., bottle or vial). 10 mM citrate, pH 3.1, 10% CAPTISOL® (Ligand; San Diego, CA) was added to the vessel with compound material to a final volume that resulted in a carfilzomib concentration of 0.3 mg / mL and 1 mg / mL. 10 mM citrate, pH 3.1, 25% CAPTISOL® was added to the vials with compound material to a final volume that resulted in a carfilzomib concentration of 5 mg / mL. The samples were stirred for 20 h at room temperature to allow for dissolution of the material. The samples were aseptically filled into vials, stoppered and capped. The samples were frozen at -70 °C for a period of 1 week prior to transport and dosing.

[0089] Vehicle solutions were prepared using the same procedure and contained the following: 10 mM citrate, pH 3.1, 10% CAPTISOL® and 10mM citrate, pH 3.1, 25% CAPTISOL®.1.2 Animal Dosing Study Design

[0090] Male BALB / c mice were distributed into seven groups as shown in Table 1 . Hyaluronidase (PH20) was administered first to the appropriate animals via subcutaneous injection into the lower flank (caudodorsal back) area once on Day 1 . The test and control articles were then administered to the appropriate animals via subcutaneous injection into the lower flank (caudodorsal back) area once on Day 1 . The second injection was made as close as possible (e.g., within 5 mm) of the site of the first injection. Samples from 6 male animals were collected from each group; 3 mice were bled at 1 h, 4 h and 24 h and 3 mice were bled at 2 h, 6 h, and 24 hours. Carfilzomib dose level (mg / kg) was maintained at the same 5 mg / kg among all the groups.1n=6 for each group; route of administration was subcutaneous

[0091] Blood samples were taken on Day 1 after dosing and tissues (heart, liver, kidney, brain and adrenal glands) were collected for all groups at 24 h post-dose. Pharmacodynamics testing was conducted on the blood pellets from samples collected at 1, 2, 4, 6, and 24 h post-dose (Table 2). The dosing, monitoring, sample collection and processing to blood lysates were performed. Tissues were snap frozen on dry ice after collection. Samples were then shipped to a lab for pharmacodynamic testing. The pharmacodynamic response was determined by measurement of proteasome activity in whole blood (primarily erythrocytes) and tissues using a fluorogenic substrate of the chymotrypsin-like activity of the proteasome.Table 2: Sample Collection Schedulea Collections at 1, 2, 4, and 6 hours postdose were non-terminal. b Collections at 24 hours postdose were followed immediately by euthanasia. A time range of 24 to 26 hours after the last dose was considered acceptable.1 .3 Proteasome Activity Assay

[0092] Proteolysis of a fluorescent tetrapeptide by the chymotrypsin-like (CT-L) activity of the proteasome was used to measure proteasome activity. Whole blood was lysed in 2 volumes of cold (4 °C) lysis buffer (20 mM Tris, pH 8.0, 5 mM EDTA) and snap frozen. Tissues were collected and snap frozen on dry ice. Frozen tissue samples and lysates of whole blood were stored at -80 °C until analyzed. All tissue samples were thawed on ice for 30 min, and then resuspended in cold lysis buffer. 300 piL of lysis buffer was used for approximately 0.1 g samples. Tissue samples were homogenized for 30 seconds on each side at 30 Hz in a Tissuelyser (Qiagen). Homogenized tissue samples and lysed whole blood samples were then spun at 14,000 rpm in a microcentrifuge at 4 °C for 15 minutes at maximum speed. 180 piL of lysates (supernatant) was then aliquoted into two 384-deep-well blocks. Plates were thawed a single time before analysis. After thawing on ice, lysates were diluted into lysis buffer, and protein concentration was determined via BCA protein assay (Pierce) using a BSA standard. Depending on protein concentrations, samples were adjusted with Assay Buffer (20 mM Tris, pH 8.0, 0.5 mM EDTA) to suitable 2X concentrations (2 mg / mL for whole blood and 0.7 mg / mL for tissues). Finally, 2X Suc-LLVY-AMC substrate (120 piM in Assay Buffer containing 2% DMSO) was added to the lysate and the fluorescence was monitored over time. Data are reported as the mean percent activity versus control article activity at respective time points. This number is a simple percent calculation obtained through equation 1 below, where the nM AMC is the concentration of the fluorescent product released in the CT-L proteasome reaction: Equation 1 : 100 * (sample nM AMC / sec / pig protein) / (vehicle AMC / sec / pig protein)1 .4 Carfi Izomi b Sample Analysis

[0093] All carfilzomib formulations were uniform, no visible particulates were noted during appearance testing. Endotoxin testing resulted in readings of less than 1.0 EU / mL for all formulations prepared. Aliquots of all pre and post dose formulations were taken and analyzed by HPLC using a 48 -minute reversed phase gradient method with UV detection. All formulations showed main peak carfilzomib percentages in the 97.8-98.5% range. Pre and post dose analysis of carfilzomib showed that active drug was at concentration of within 1 % of target. Carfilzomib samples were stable for the duration of the dosing. No notable decrease of main peaks were observed for any of the samples tested.1.5 Proteasomal Inhibition Activity of the Various Formulations
