ALISERTIB AND PACLITAXEL FOR TREATING SMALL CELL LUNG CANCERCROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 587,628 filed October 3, 2023, the disclosure of which is incorporated herein by reference in its entirety.FIELD
[0002] Provided herein are methods for the treatment of small cell lung cancer (SCLC) comprising administering alisertib. Specific patient populations are contemplated in the methods and compositions disclosed herein, including patients with certain biomarkers and / or genetic profiles as well as resistant or refractory patients with certain biomarkers and / or genetic profiles. Also provided herein are methods for the treatment of small cell lung cancer (SCLC) comprising administering alisertib and a taxane. Further, provided herein are pharmaceutical compositions and dosage forms of alisertib. Further provided herein are methods for using the pharmaceutical compositions, and dosage forms of alisertib for treating and / or managing SCLC.BACKGROUND
[0003] Small cell lung cancer (SCLC) is an aggressive malignancy, accounting for 13% to 18% of all lung cancer diagnoses (Alvarado-Luna G, et al., Transl Lung Cancer Res. 2016;5:26- 38. 3; Sorensen M, et al., Ann Oncol. 2010;21(suppl 5):vl20-vl25; Arcaro A. Crit Rev Oncol Hematol. 2015;95:154-164). In treated extensive-stage SCLC, the median overall survival (OS) is just 7 to 12 months. (Hamilton G, et al., Transl Lung Cancer Res. 2016;5:71-77.) The prognosis for relapsed or refractory SCLC is more dismal, with a median OS of 4 to 5 months. (Jett JR, et al., Chest. 2013;143:e400S-e419S.) Response rates are particularly poor (≤ 10%) in patients with resistant or refractory disease who relapse 3 months or less from the end of initial therapy. (Chest. 2013;143:e400S-e419S). Patients with platinum-sensitive disease (relapse >3 months from end of initial therapy) have a relatively better outcome (response rate approximately 25%).
[0004] Aurora A kinase (AAK), is a key regulator of mitosis. (Barr AR, et al. J Cell Sci. 2007;120:2987-2996). AAK is amplified or overexpressed in several solid tumors, includingSCLC, and may play a role in tumorigenesis.. Knocking down the expression of Aurora-A gene inhibits cell proliferation and induces G2 / M phase arrest in human small cell lung cancer cells. Oncol Rep. 2014;32:243-249; Marumoto T, et al. J Biol Chem. 2003;278:51786-51795).Inhibition of AAK leads to disrupted mitosis and cell death, reduced proliferation, and induction of apoptosis in SCLC cells. (Oncol Rep. 2014;32:243-249; Cowley DO, et al., Mol Cell Biol.2009;29:1059-1071.)
[0005] Amplification of v-myc avian myelocytomatosis viral oncogene homolog gene (MYC) in SCLC cell lines is associated with improved sensitivity to Aurora kinase inhibitors. (Hook KE, et al. Mol Cancer Ther. 2012; 11 :710-719; Sos ML, et al. Proc Natl Acad Sci USA. 2012;109:17034-17039). Amplification and overexpression of the MYC gene family occurs in 18% to 31% of SCLCs and is more common in chemorefractory disease. The gene product, c- Myc (a transcription factor), binds directly to AAK, and inhibition of this interaction by AAK inhibitors results in c-Myc degradation and cell death. (Brockmann M, et al. Cancer Cell.2013;24:75-89; Dauch D, et al. Nat Med. 2016;22:744-753). Thus, the Myc-AAK protein complex represents an actionable drug target for AAK inhibitors.
[0006] Alisertib (MLN8237) is a selective, oral, small molecule AAK inhibitor that has been studied in various solid tumors and hematologic malignancies. (Barr PM, et al. J Clin Oncol.2015;33:2399-2404; Falchook G, et al. JAMA Oncol. 2019;5:el83773; Falchook GS, et al.Drugs R D. 2016;16:45-52; Goldberg SL, et al. LeukRes Rep. 2014;3:58-61; Matulonis UA, et al. Gynecol Oncol. 2012;127:63-69; Melichar B, et al. Lancet Oncol. 2015: 16:395 405.) Single-agent activity of alisertib was demonstrated in a phase II study of patients with relapsed or refractory solid tumors, including SCLC (n = 48); in patients with SCLC, the objective response rate (ORR) was 21% and the median progression- free survival (PFS) was 2.1 months. (Melichar B, et al. Lancet Oncol. 2015;16:395-405.)
[0007] Alisertib plus paclitaxel was evaluated in patients with breast and ovarian cancer and showed promise over paclitaxel alone (JAMA Oncol. 2019;5:el83773). A Phase II study of paclitaxel plus alisertib versus paclitaxel plus placebo as second line therapy for SCLC wasconducted. (Journal of Thoracic Oncology Vol. 15 No. 2: 274-287). The study did not assess the treatment of patients with particular genetic mutations.
[0008] Because of poor responses to current treatments, there is a critical unmet medical need in patients with SCLC.BRIEF DESCRIPTION OF THE DRAWINGS

[0043] 2. Definitions
[0044] As used herein, the terms “small cell lung cancer” or “SCLC” refer to a neuroendocrine carcinoma that exhibits aggressive behavior, rapid growth, early spread to distant sites, exquisite sensitivity to chemotherapy and radiation, and frequent association with distinct paraneoplastic syndromes, including hypercalcemia, Eaton-lambert syndrome, syndrome of inappropriate antidiuretic hormone (SIADH) secretion, and many others. SCLC is divided into the 2 subtypes: oat cell carcinoma and combined- SCLC. Combined SCLC is defined as SCLC with non-small cell components such as squamous cell or adenocarcinoma. (StatPearls Publishing; 2023 Jan-. Available from: https : / / www.ncbi.nlm.nih.gov / books / NBK482458 / ).Nearly 60% of SCLC patients present with metastatic disease. Most common sites of metastases include the brain, liver, adrenal glands, bone, and bone marrow. If left untreated, SCLC is characterized by rapid tumor progression with a median survival of 2 to 4 months. Treatment is highly dependent on stage. Patients with limited-stage SCLC are candidates for curative-intent radiation therapy and chemotherapy. Patients with extensive-stage disease are treated with chemotherapy with radiation (RT) reserved for select candidates and palliation. Limited Stage: While the majority of patients present with locally advanced disease, a small minority maypresent with T1-2N0 disease. These patients may be candidates for lobectomy with mediastinal sampling or dissection. If surgery demonstrates mediastinal nodal involvement, adjuvant chemoradiation is indicated. If they are not surgical candidates, stereotactic ablative body therapy (SABR) may be employed. Adjuvant cisplatin-based systemic therapy typically follows both local approaches. The remainder of limited stage patients is treated with concurrent chemotherapy and radiation. Cisplatin and etoposide is the current standard of care. The addition of radiation to chemotherapy significantly increases local control and overall survival. The early incorporation of RT with CT has been shown to further increase overall survival compared to late incorporation. Prophylactic cranial irradiation (PCI) is indicated for patients with a complete or partial response to therapy. PCI significantly increases overall survival and decreases the incidence of brain metastases. Extensive Stage: The mainstay of therapy for patients with the extensive stage is systemic chemotherapy. Patients who have a complete or partial response to therapy can be evaluated for consolidative thoracic RT. This therapy has been associated with an increase in overall survival and is typically well tolerated. PCI is also indicated for ES and has been associated with an increase in survival with a decrease in brain metastases incidence. There is currently no role for the addition of consolidation radiation to limited volume metastatic sites. The efficacy of platinum-based chemotherapy for frontline therapy has been established in randomized clinical trials with objective responses in approximately 70% of patients with limited stage SCLC and in 50% of patients with extensive stage disease (Oncology (Williston Park) 1998;12:647-58. discussion 661-3; Oncology (Williston Park) 2008;22:1495-6; . N Engl J Med. 2002;346:85-91.) Despite this high initial response, the majority of SCLC patients require salvage therapy for disease progression within several months following frontline therapy. (J Thorac Oncol. 2012 May; 7(5): 866-872.)
[0045] As used herein, the term “patient” means an animal, in one embodiment a mammal, and in another embodiment a human. In some embodiments, the patient has a pathologically (histologically or cytologically) confirmed diagnosis of SCLC. In one embodiment, the patient has progressed within 180 days of last platinum dose, after receiving a standard platinum-based chemotherapy regimen as first-line treatment and has measurable disease per the Response Evaluation Criteria in Solid Tumors version 1.1. In one embodiment, the patient has not received prior treatment with an Aurora A kinase inhibitor (e.g., alisertib), a pan- Aurora-targetedagent, paclitaxel, or any other taxane. In one embodiment, the patient has not received prior treatment with any other investigational agent for relapsed disease. In one embodiment, the patient has limited stage SCLC. In one embodiment, the patient has extensive stage SCLC.
[0046] The term “mutation” as used herein refers to an alteration in a gene or protein which is not present in the wild-type gene or protein. The terms “mutant,” “mutation,” or “mutations” as used herein are interchangeable. In one embodiment, the term “mutant” as used herein encompasses one or more mutations and is not limited to a single mutational status.
[0047] The terms “sensitive,” “sensitive relapse,” or “platinum sensitive” as used herein refer to SCLC in which progression of disease is observed >90 days from the last dose of first-line platinum-based chemotherapy.
[0048] The term “resistant” or “resistant relapse” as used herein refers to SCLC in which progression of disease is observed ≤90 days after first-line platinum-based chemotherapy.
[0049] The term “refractory” or “refractory relapse” as used herein refers to SCLC in which no objective response is achieved and disease progression occurs either during or immediately after first-line platinum-based chemotherapy.
[0050] It will be understood that encompassed herein is SCLC which is resistant / refractory or relapsed SCLC, resistant / refractory SCLC, platinum sensitive SCLC, platinum-resistant SCLC, platinum resistant or refractory SCLC, and sensitive relapse SCLC.
[0051] The term “c-Myc positive” as used herein refers to SCLC positive for c-Myc expression. In one embodiment, c-Myc positive as used herein refers to c-Myc expression measured by immunohistochemistry analysis in which modal intensity is 1+, 2+, or 3+. In one embodiment, c-Myc positive includes c-Myc overexpression and / or amplification, and / or c-Myc alteration.
[0052] An improvement in SCLC can be characterized as a complete or partial response. “Complete response” (CR) refers to disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to about < 10 mm.“Partial response” (PR) refers to at least about a 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or90% decrease in all measurable tumor burden (i.e., decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters) in the absence of new lesions. The term “treatment” contemplates both a complete and a partial response. “Progressive Disease” (PD): refers to at least about a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of about 20%, the sum must also demonstrate an absolute increase of at least about 5 mm. The appearance of one or more new lesions is also considered progression. “Stable Disease” (SD) refers to neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.
[0053] As used herein, and unless otherwise specified, the term “sensitivity” and “sensitive” when made in reference to treatment with a compound disclosed herein is a relative term which refers to the degree of effectiveness of the compound in lessening or decreasing the progress of SCLC. For example, the term “increased sensitivity” when used in reference to treatment of SCLC in connection with a compound disclosed herein refers to an increase of, at least a 5%, or more, in the effectiveness of the SCLC treatment.
[0054] As used herein, and unless otherwise specified, the terms “determining”, “measuring”, “evaluating”, “assessing” and “assaying” as used herein generally refer to any form of measurement, and include determining if an element is present or not. These terms include both quantitative and / or qualitative determinations. Assessing may be relative or absolute.“Assessing the presence of” can include determining the amount of something present, as well as determining whether it is present or absent.
[0055] The expressions “therapeutically effective” and “therapeutic effect” refer to a benefit including, but not limited to, the treatment or amelioration of symptoms of a disorder discussed herein. It will be appreciated that the therapeutically effective amount or the amount of agent required to provide a therapeutic effect will vary depending upon the intended application (in vitro or in vivo), or the subject and disease condition being treated (e.g., nature of the severity ofthe condition to be treated, the particular inhibitor, the route of administration and the age, weight, general health, and response of the individual patient), which can be readily determined by a person of skill in the art. For example, an amount of a selective inhibitor of Aurora A kinase such as alisertib with an amount of a taxane such as paclitaxel is therapeutically effective if it is sufficient to effect the treatment or amelioration of symptoms of a disorder discussed herein.
[0056] The expressions “prophylactically effective” and “prophylactic effect” refer to a benefit including, but not limited to, the prophylaxis of symptoms of SCLC discussed herein. It will be appreciated that the prophylactically effective amount or the amount of agent required to provide a prophylactic effect will vary depending upon the intended application (in vitro or in vivo), or the subject and disease condition being prevented (e.g., nature of the severity of the condition to be prevented, the particular inhibitor, the route of administration and the age, weight, general health, and response of the individual patient), which can be readily determined by a person of skill in the art. For example, an amount of alisertib with an amount of a taxane such as paclitaxel is prophylactically effective if it is sufficient to effect the prophylaxis of symptoms of SCLC discussed herein. In one embodiment, the symptom is neutropenia. In another embodiment, a prophylactically effective amount of an agent is an amount effective to reduce grade 3 or higher neutropenia.

[0057] As used herein, the term “taxane” refers to a class of diterpenes produced by the plants of the genus Taxus (yews). Examples of taxanes include, but are not limited to, paclitaxel(TAXOL®), docetaxel (TAXOTERE®), ABRAXANE® (Paclitaxel Injection), and nab- paclitaxel (nanoparticle albumin-bound paclitaxel).
[0058] As used herein, the term “in combination” refers to use of both alisertib and a taxane in the treatment of the same disease or condition in the same patient and may include a further therapeutic agent (e.g, G-CSF). As further described below, unless explicitly specified, the term “in combination” does not restrict the timing and mode of administration of alisertib, the taxane, or other therapeutic agent.
[0059] As used herein, and unless otherwise specified, the term “about” or “approximately” means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined. In certain embodiments, the term “about” or “approximately” means within 1, 2, 3, or 4 standard deviations. In certain embodiments, the term “about” or “approximately” means within 50%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, or 0.05% of a given value or range.
[0060] As used herein, the term “or” is to be interpreted as an inclusive “or” meaning any one or any combination. Therefore, “A, B or C” means any of the following: “A; B; C; A and B; A and C; B and C; A, B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive. CLINICAL TRIAL ENDPOINTS FOR SCLC APPROVAL
[0061] Overall survival” (OS) is defined as the time from first dose until death from any cause, and is measured in the intent-to-treat population. Overall survival should be evaluated in randomized controlled studies. Demonstration of a statistically significant improvement in overall survival can be considered to be clinically significant if the toxicity profile is acceptable, and has often supported new drug approval. In one embodiment, patients are followed for overall survival (OS) every 2 months (±2 weeks) until approximately 80% of all patients in the intent-to-treat (ITT) population have died or 14 months after the last patient was randomized, whichever occurred first.
[0062] Several endpoints are based on SCLC assessments. These endpoints include disease free survival (DFS), objective response rate (ORR), including complete response, time to progression (TTP), progression-free survival (PFS), event-free survival (EFS), duration of response (DOR), disease control rate (DCR), time-to-treatment failure (TTF), safety and / or tolerability. The collection and analysis of data on these time-dependent endpoints are based on indirect assessments, calculations, and estimates. In one embodiment, end points such as safety and / or tolerability, OS, ORR including complete response, and DCR as used herein are secondary end points. Generally, “disease free survival” (DFS) is defined as the time from randomization until recurrence of cancer or death from any cause. Although overall survival is a conventional endpoint for most adjuvant settings, DFS can be an important endpoint in situations where survival may be prolonged, making a survival endpoint impractical. DFS can be a surrogate for clinical benefit or it can provide direct evidence of clinical benefit. This determination is based on the magnitude of the effect, its risk-benefit relationship, and the disease setting. The definition of DFS can be complicated, particularly when deaths are noted without prior cancer progression documentation. These events can be scored either as disease recurrences or as censored events. Although all methods for statistical analysis of deaths have some limitations, considering all deaths (deaths from all causes) as recurrences can minimize bias. DFS can be overestimated using this definition, especially in patients who die after a long period without observation. Bias can be introduced if the frequency of long-term follow-up visits is dissimilar between the study arms or if dropouts are not random because of toxicity.
[0063] “Objective response rate” (ORR) is defined as the sum of the percentage of patients who achieve complete and partial responses. Response duration usually is measured from the time of initial response until documented cancer progression. Generally, the FDA has defined ORR as the sum of partial responses plus complete responses. When defined in this manner, ORR is a direct measure of drug anticancer activity, which can be evaluated in a single-arm study. If available, standardized criteria should be used to ascertain response. A variety of response criteria have been considered appropriate (e.g., RECIST criteria) (Therasse et al.,(2000) J. Natl. Cancer Inst, 92: 205-16). The significance of ORR is assessed by its magnitude and duration, and the percentage of complete responses (no detectable evidence of cancer).
[0064] “Duration of response” (DOR) is the time from achieving a response until relapse or disease progression.
[0065] “Time to progression” (TTP) and “progression-free survival” (PFS) have served as primary endpoints for drug approval. TTP is defined as the time from randomization until objective cancer progression; TTP does not include deaths. PFS is defined as the time from randomization until objective cancer progression or death. Compared with TTP, PFS is the preferred regulatory endpoint. PFS includes deaths and thus can be a better correlate to overall survival. PFS assumes patient deaths are randomly related to cancer progression. However, in situations where the majority of deaths are unrelated to cancer, TTP can be an acceptable endpoint.
[0066] As an endpoint to support drug approval, PFS can reflect cancer growth and be assessed before the determination of a survival benefit. Its determination is not confounded by subsequent therapy. For a given sample size, the magnitude of effect on PFS can be larger than the effect on overall survival. However, the formal validation of PFS as a surrogate for survival for the many different malignancies that exist can be difficult. Data are sometimes insufficient to allow a robust evaluation of the correlation between effects on survival and PFS. Cancer trials are often small, and proven survival benefits of existing drugs are generally modest. The role of PFS as an endpoint to support licensing approval varies in different cancer settings. Whether an improvement in PFS represents a direct clinical benefit or a surrogate for clinical benefit depends on the magnitude of the effect and the risk-benefit of the new treatment compared to available therapies. In one embodiment, PFS as contemplated herein, is a primary end point. In one such embodiment, PFS is measured as time from randomization to progressive disease or death. In one such embodiment, patients are stratified by type of relapse after primary treatment (sensitive versus resistant or refractory disease) and presence of brain metastases. In one embodiment, PFS is also analyzed in patient subgroups according to baseline characteristics.
[0067] “Event- free survival” (EFS) is the time from study entry until any treatment failure, including disease progression, treatment discontinuation for any reason, or death.
[0068] ‘Time-to-treatment failure” (TTF) is defined as a composite endpoint measuring time from randomization to discontinuation of treatment for any reason, including disease progression, treatment toxicity, and death. TTF is not recommended as a regulatory endpoint for drug approval. TTF does not adequately distinguish efficacy from these additional variables. A regulatory endpoint should clearly distinguish the efficacy of the drug from toxicity, patient or physician withdrawal, or patient intolerance.
[0069] “Disease control rate” (DCR) is defined as complete response, partial response, or stable disease ≥ 8 weeks.
[0070] In one embodiment, encompassed herein are exploratory end points including correlative biomarker studies to evaluate the impact of c-Myc expression and / or genetic alterations on clinical outcomes (PFS and OS).
[0071] In certain embodiments, the methods provided herein are useful for achieving one or more of these clinical trial endpoints in a patient. In certain embodiments, the methods provided herein are useful for improving one or more of these clinical trial endpoints in a patient. In certain embodiments, the methods provided herein increase PFS relative to treatment of SCLC with a taxane. In some embodiments, the method of treating SCLC comprising alisertib and paclitaxel as provided herein increases PFS relative to treatment of SCLC with paclitaxel. In some embodiments, such increase in PFS is 2 fold, 3 fold, or 4 fold, or by 10%, 20%, 25%, 30%, 35, or 40%. In certain embodiments, the methods provided herein increase OS relative to treatment of SCLC with a taxane. In some embodiments, the method of treating SCLC comprising alisertib and paclitaxel as provided herein increases OS relative to treatment of SCLC with paclitaxel. In some embodiments, such increase in OS is 2 fold, 3 fold, or 4 fold, or by 10%, 20%, 25%, 30%, 35%, or 40%. In some such embodiments, the taxane is paclitaxel or nab-paclitaxel.

[0087] Additionally, it will be appreciated that the frequency with which any of these therapeutic agents can be administered can be once or more than once over a period of about 2 days, about 3 days, about 4 days, about 5 days, about 6 days, about 7 days, about 8 days, about 9 days, about 10 days, about 20 days, about 28 days, about a week, about 2 weeks, about 3 weeks, about 4 weeks, about a month, about every 2 months, about every 3 months, about every 4 months, about every 5 months, about every 6 months, about every 7 months, about every 8 months, about every 9 months, about every 10 months, about every 11 months, about every year, about every 2 years, about every 3 years, about every 4 years, or about every 5 years.
[0088] For example, an agent may be administered daily, weekly, biweekly, or monthly for a particular period of time. In some embodiments, a certain amount of alisertib can be administered on a daily basis over a period of three days. Alternatively, an agent may be administered daily, weekly, biweekly, or monthly for a particular period of time followed by a particular period of non-treatment. In some embodiments, a certain amount of alisertib can be administered daily for three days followed by four days of no administration, followed by administration daily for three days followed by four more days of no administration, followed by administration daily for three days followed by four more days of no administration. In some embodiments, a certain amount of a taxane can be administered weekly over a three week period.
[0089] In some embodiments, alisertib and the taxane are cyclically administered to a patient. Cycling therapy involves the administration of a first agent (e.g., a first prophylactic or therapeutic agents) for a period of time, followed by the administration of a second agent and / or third agent (e.g., a second and / or third prophylactic or therapeutic agents) for a period of time and repeating this sequential administration. Cycling therapy can reduce the development of resistance to one or more of the therapies, avoid or reduce the side effects of one of the therapies, and / or improve the efficacy of the treatment.
[0090] In one embodiment, alisertib and the taxane are administered for at least 1 to 12 cycles. In one embodiment, alisertib and the taxane are administered for at least 1 to 6 cycles. In one embodiment, alisertib and the taxane are administered for at least 1 cycle. In one embodiment, alisertib and the taxane are administered for at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, or at least 12 cycles. In one embodiment, alisertib and the taxane are administered for at least 1 cycle. In one embodiment, alisertib and the taxane are administered for at least 2 cycles. In one embodiment, alisertib and the taxane are administered for at least 3 cycles. In one embodiment, alisertib and the taxane are administered for at least 4 cycles. In one embodiment, alisertib and the taxane are administered for at least 5 cycles. In one embodiment, alisertib and the taxane are administered for at least 6 cycles.
[0091] In some embodiments, the treatment period during which an agent is administered is then followed by a non-treatment period of a particular time duration, during which the therapeutic agents are not administered to the patient. This non-treatment period can then be followed by a series of subsequent treatment and non-treatment periods of the same or different frequencies for the same or different lengths of time. In some embodiments, the treatment and non-treatment periods are alternated. It will be understood that the period of treatment in cycling therapy may continue until the patient has achieved a complete response or a partial response, at which point the treatment may be stopped. Alternatively, the period of treatment in cycling therapy may continue until the patient has achieved a complete response or a partial response, at which point the period of treatment may continue for a particular number of cycles. In some embodiments, the length of the period of treatment may be a particular number of cycles, regardless of patient response. In some other embodiments, the length of the period of treatment may continue until the patient relapses.
[0092] For example, a certain amount of alisertib can be administered twice daily for 3 days followed by 11 days of non-treatment followed by 3 days of twice daily administration. In some embodiments, the treatment and non-treatment periods are alternated. In other embodiments, afirst treatment period in which a first amount of alisertib is administered can be followed by another treatment period in which a same or different amount of the same alisertib is administered. The second treatment period can be followed by other treatment periods. During the treatment and non-treatment periods, one or more additional therapeutic agents can be administered to the patient.
[0093] In one embodiment, the administration is on a 21 -day dose schedule in which alisertib is administered twice-daily in a schedule of 7 days on followed by 14 days off. In some embodiments, a first treatment period in which a first amount of alisertib is administered can be followed by another treatment period in which a same or different amount of the same alisertib is administered. The second treatment period can be followed by other treatment periods. During the treatment and non-treatment periods, one or more additional therapeutic agents can be administered to the patient.

[0116] A wide variety of therapeutic agents may have a therapeutically relevant added benefit in combination with alisertib and a taxane of the present disclosure. Combination therapies that comprise alisertib and a taxane disclosed herein with one or more other therapeutic agents can be used, for example, to: 1) enhance the therapeutic effect(s) of the methods disclosed herein and / or the one or more other therapeutic agents; 2) reduce the side effects exhibited by the methods disclosed herein and / or the one or more other therapeutic agents; and / or 3) reduce theeffective dose of alisertib and / or the taxane of the present disclosure and / or the one or more other therapeutic agents.
[0117] In some embodiments, the method disclosed herein comprises administration of alisertib and a taxane and an additional therapeutic agent, wherein the amounts of each agent are therapeutically effective when used in combination.
[0118] In certain embodiments, alisertib and a taxane are administered with the concomitant or sequential administration of cisplatin or doxorubicin. It will be appreciated that the therapy includes administration of the therapeutic agents concurrently or sequentially. Alternatively, the therapeutic agents can be combined into one composition which is administered to the patient.
[0119] Examples of therapeutic agents that may be used in combination with alisertib and a taxane of the present disclosure include, but are not limited to, anti-proliferative agents, anticancer agents, alkylating agents, antibiotic agents, antimetabolic agents, hormonal agents, plant-derived agents, and biologic agents. Examples of some of the above classes of additional therapeutic agents are listed below for purposes of illustration and not for purposes of limitation, as these examples are not all-inclusive. Many of the examples below could be listed in multiple classes of anti-cancer agents and are not restricted in any way to the class in which they are listed.
[0120] Alkylating agents are polyfunctional compounds that have the ability to substitute alkyl groups for hydrogen ions. Examples of alkylating agents include, but are not limited to, bischloroethylamines (nitrogen mustards, e.g. chlorambucil, cyclophosphamide, ifosfamide, mechlorethamine, melphalan, uracil mustard), aziridines (e.g. thiotepa), alkyl alkone sulfonates (e.g. busulfan), nitrosoureas (e.g. carmustine, lomustine, streptozocin), nonclassic alkylating agents (altretamine, dacarbazine, and procarbazine), platinum compounds (carboplastin and cisplatin). These compounds react with phosphate, amino, hydroxyl, sulfihydryl, carboxyl, and imidazole groups. Under physiological conditions, these drugs ionize and produce positively charged ion that attach to susceptible nucleic acids and proteins, leading to cell cycle arrest and / or cell death. Combination therapy including a compound of the present disclosure and analkylating agent may have therapeutic synergistic effects on cancer and reduce sides affects associated with these chemotherapeutic agents.
[0121] Antibiotic agents are a group of drugs that produced in a manner similar to antibiotics as a modification of natural products. Examples of antibiotic agents include, but are not limited to, anthracyclines (e.g. doxorubicin, daunorubicin, epirubicin, idarubicin and anthracenedione), mitomycin C, bleomycin, dactinomycin, plicatomycin. These antibiotic agents interfere with cell growth by targeting different cellular components. For example, anthracyclines are generally believed to interfere with the action of DNA topoisomerase II in the regions of transcriptionally active DNA, which leads to DNA strand scissions. Bleomycin is generally believed to chelate iron and forms an activated complex, which then binds to bases of DNA, causing strand scissions and cell death. Combination therapy including a compound of the present disclosure and an antibiotic agent may have therapeutic synergistic effects on cancer and reduce sides affects associated with these chemotherapeutic agents.
[0122] Antimetabolic agents are a group of drugs that interfere with metabolic processes vital to the physiology and proliferation of cancer cells. Actively proliferating cancer cells require continuous synthesis of large quantities of nucleic acids, proteins, lipids, and other vital cellular constituents. Many of the antimetabolites inhibit the synthesis of purine or pyrimidine nucleosides or inhibit the enzymes of DNA replication. Some antimetabolites also interfere with the synthesis of ribonucleosides and RNA and / or amino acid metabolism and protein synthesis as well. By interfering with the synthesis of vital cellular constituents, antimetabolites can delay or arrest the growth of cancer cells. Examples of antimetabolic agents include, but are not limited to, fluorouracil (5-FU), floxuridine (5-FUdR), methotrexate, leucovorin, hydroxyurea, thioguanine (6-TG), mercaptopurine (6-MP), cytarabine, pentostatin, fludarabine phosphate, cladribine (2-CDA), asparaginase, and gemcitabine. Combination therapy including a compound of the present disclosure and a antimetabolic agent may have therapeutic synergistic effects on cancer and reduce sides affects associated with these chemotherapeutic agents.
[0123] Hormonal agents are a group of drug that regulate the growth and development of their target organs. Most of the hormonal agents are sex steroids and their derivatives and analogs thereof, such as estrogens, androgens, and progestins. These hormonal agents may serve as antagonists of receptors for the sex steroids to down regulate receptor expression and transcription of vital genes. Examples of such hormonal agents are synthetic estrogens (e.g. diethylstibestrol), antiestrogens (e.g. tamoxifen, toremifene, fluoxymesterol and raloxifene), antiandrogens (bicalutamide, nilutamide, and flutamide), aromatase inhibitors (e.g., aminoglutethimide, anastrozole and tetrazole), ketoconazole, goserelin acetate, leuprolide, megestrol acetate and mifepristone. Combination therapy including a compound of the present disclosure and a hormonal agent may have therapeutic synergistic effects on cancer and reduce sides effects associated with these chemotherapeutic agents.
[0124] Plant-derived agents are a group of drugs that are derived from plants or modified based on the molecular structure of the agents. Examples of plant-derived agents include, but are not limited to, vinca alkaloids (e.g., vincristine, vinblastine, vindesine, vinzolidine and vinorelbine), and podophyllotoxins (e.g., etoposide (VP- 16) and teniposide (VM-26)). These plant-derived agents generally act as antimitotic agents that bind to tubulin and inhibit mitosis. Podophyllotoxins such as etoposide are believed to interfere with DNA synthesis by interacting with topoisomerase II, leading to DNA strand scission. Combination therapy including a compound of the present disclosure and a plant-derived agent may have therapeutic synergistic effects on cancer and reduce sides affects associated with these chemotherapeutic agents.
[0125] Biologic agents are a group of biomolecules that elicit cancer / tumor regression when used alone or in combination with chemotherapy and / or radiotherapy. Examples of biologic agents include, but are not limited to, immuno-modulating proteins such as cytokines, monoclonal antibodies against tumor antigens, tumor suppressor genes, and cancer vaccines. Combination therapy including a compound of the present disclosure and a biologic agent may have therapeutic synergistic effects on cancer, enhance the patient’s immune responses totumorigenic signals, and reduce potential sides affects associated with this chemotherapeutic agent.
[0126] Cytokines possess profound immunomodulatory activity. Some cytokines such as interleukin-2 (IL-2, aldesleukin) and interferon have demonstrated antitumor activity and have been approved for the treatment of patients with metastatic renal cell carcinoma and metastatic malignant melanoma. IL-2 is a T-cell growth factor that is central to T-cell-mediated immune responses. The selective antitumor effects of IL-2 on some patients are believed to be the result of a cell-mediated immune response that discriminate between self and nonself. Examples of interleukins that may be used in conjunction with the compounds disclosed herein include, but are not limited to, interleukin 2 (IL-2), and interleukin 4 (IL-4), interleukin 12 (IL-12).
[0127] Interferons include more than 23 related subtypes with overlapping activities, all of the IFN subtypes are within the scope of the present disclosure. IFN has demonstrated activity against many solid and hematologic malignancies, the later appearing to be particularly sensitive.
[0128] Other cytokines that may be used in conjunction with the compounds disclosed herein include those cytokines that exert profound effects on hematopoiesis and immune functions.Examples of such cytokines include, but are not limited to erythropoietin, granulocyte-CSF (G- CSF, filgrastim or Neupogen®), and granulocyte, macrophage-CSF (sargramostim). These cytokines may be used in conjunction with a compound disclosed herein to reduce chemotherapy-induced myelopoietic toxicity.
[0129] Other immuno-modulating agents other than cytokines may also be used in conjunction with the compounds disclosed herein to inhibit abnormal cell growth. Examples of such immuno-modulating agents include, but are not limited to bacillus Calmette-Guerin, levamisole, and octreotide, a long-acting octapeptide that mimics the effects of the naturally occurring hormone somatostatin.
[0130] Tumor suppressor genes are genes that function to inhibit the cell growth and division cycles, thus preventing the development of neoplasia. Mutations in tumor suppressor genes cause the cell to ignore one or more of the components of the network of inhibitory signals,overcoming the cell cycle check points and resulting in a higher rate of controlled cell growth — cancer. Examples of the tumor suppressor genes include, but are not limited to, DPC-4, NF-1, NF-2, RB, p53, WT1, BRCA1, and BRCA2.
[0131] RB codes for the pRB protein, a nuclear protein that is a major inhibitor of cell cycle. RB is involved in retinoblastoma as well as bone, bladder, small cell lung and breast cancer. P53 codes for p53 protein that regulates cell division and can induce apoptosis. Mutation and / or inaction of p53 is found in a wide ranges of cancers, including SCLC. The tumor suppressor gene can be transferred into the tumor cells where it exerts its tumor suppressing functions. Combination therapy including a compound disclosed herein and a tumor suppressor may have therapeutic synergistic effects on patients suffering from SCLC.
[0132] Cancer vaccines are a group of agents that induce the body’s specific immune response to tumors. Most of cancer vaccines under research and development and clinical trials are tumor-associated antigens (TAAs). TAA are structures (i.e. proteins, enzymes or carbohydrates) which are present on tumor cells and relatively absent or diminished on normal cells. By virtue of being fairly unique to the tumor cell, TAAs provide targets for the immune system to recognize and cause their destruction. Example of TAAs include, but are not limited to gangliosides (GM2), prostate specific antigen (PSA), alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA) (produced by colon cancers and other adenocarcinomas, e.g. breast, lung, gastric, and pancreas cancer s), melanoma associated antigens (MART-1, gp100, MAGE 1,3 tyrosinase), papillomavirus E6 and E7 fragments, whole cells or portions / lysates of autologous tumor cells and allogeneic tumor cells.
[0133] An adjuvant may be used to augment the immune response to TAAs. Examples of adjuvants include, but are not limited to, bacillus Calmette-Guerin (BCG), endotoxin lipopolysaccharides, keyhole limpet hemocyanin (GKLH), interleukin-2 (IL-2), granulocytemacrophage colony-stimulating factor (GM-CSF) and cytoxan, a chemotherapeutic agent which is believe to reduce tumor-induced suppression when given in low doses.
[0134] In certain embodiments, the one or more additional treatments is selected from radiation, chemotherapy, immunotherapy, or other targeted anticancer therapy.

No previous irradiation to a site of measurable or evaluable disease was permitted, unless there was evidence of progression. Patients who had not fully recovered from surgery within 3 weeks (2 weeks for minor surgery), or radiation therapy within 2 weeks, of enrolment could not be included in the study.
[0152] Other key exclusion criteria included: prior history of grade ≥2 neurotoxicity that was not resolved to grade ≤1; symptomatic and / or progressive brain metastases or carcinomatous meningitis; treatment with clinically significant enzyme inducers within 14 days of the first dose of study drug or requirement for treatment with a proton pump inhibitor, H2 antagonist, or pancreatic enzymes; prior history of malignancy (within 3 years of the first dose of study drug orwith any residual disease); or any other severe acute or chronic medical or psychiatric condition that would make the patient unsuitable for the study (including uncontrolled diabetes or cardiovascular disease).
[0153] iii. Assessment of c-Myc Expression
[0154] c-Myc expression was assessed in archival tumor tissue samples (obtained prior to treatment), if available, by immunohistochemical analysis of formalin-fixed, paraffin-embedded tissue blocks. The c-Myc immunohistochemistry assay was a clinically validated test from PhenoPath (Seattle, WA, USA). Slides were incubated with the primary antibody (c-Myc Y69, Abeam, ab32072) and 3,3 ’-diaminobenzidine was used as the detection chromogen. Whole slide scans were scored by a trained pathologist for percent positive tumor cells and modal intensity (0, 1+, 2+, 3+).
[0155] iv. Next-Generation Sequencing of Circulating Tumor DNA
[0156] Baseline plasma samples were requested from all patients enrolled on the study Plasma samples were collected and processed for next-generation sequencing (NGS) analysis of circulating tumor DNA (ctDNA). Patient samples were sequenced successfully, and mutations were called in and used for the correlative analysis. A custom PlasmaSelect-R™ (Personal Genome Diagnostics, Inc., Baltimore, MD, USA) targeted gene NGS panel was designed to evaluate 80 genes selected based on recurrent dysregulation in the small-cell lung cancer (SCLC) literature (Table 1). Genes involved in cell cycle regulation, NOTCH and phosphoinositide 3- kinase (PI3K) signaling, and histone modification, along with other known oncogenic activating mutations, were selected. Full coding regions were analyzed in all 80 genes, with copy number variations specifically analyzed for AURKA and MYC. Although CRIPAK was included on the gene panel, these results were excluded from the correlative analyses due to its status as a potential pseudogene. (Abascal F, et al. Nucleic Acids Res. 2018;46:7070-7084.) The assay targets a read coverage of 20,000x with sensitivity >0.1% for single nucleotide variants and >0.2% for amplifications.
[0157] v. Statistical Methods
[0158] Assuming a median PFS of 3 months for the placebo / paclitaxel arm, and that alisertib / paclitaxel could improve median PFS to 5 months (a 40% reduction of hazard), a minimum of 138 PFS events were required for the primary analysis (two-sided alpha: 0.05; power 85%). Patient enrollment was estimated based on 16 months of accrual (at 6-13 patients per month), 6 months of PFS follow-up, a dropout rate of about 15%, and 1 : 1 randomization to treatment.
[0159] PFS was tested using a two-sided stratified (by randomization stratification factors) log-rank test to compare treatment arms (alpha: 0.05). Hazard ratios (HRs) and 95% confidence intervals (CI) were estimated using a stratified Cox proportional hazard regression model, with treatment as the explanatory variable. Kaplan-Meier survival curves were provided for each arm. OS and other time-to-event endpoints were analyzed using similar methods. Death events were to be obtained from approximately 80% of patients in the ITT population or at 14 months after the last patient was randomized. Duration of response was summarized descriptively for responders only.
[0160] Stratified Cochran-Mantel-Haenszel tests were used to compare responses (overall response rate [complete response or partial response] and disease control rate) between arms, with logistic regression models used to estimate treatment effect.
[0161] Assessment of c-Myc expression by immunohistochemistry was analyzed in two ways: percentage of positive cells or a dichotomized readout converted to a binary variable (positive / negative) based on the modal intensity. For both methods, a Cox proportional hazard model was used to analyze PFS, with treatment and c-Myc expression as the main effects; their interaction was also assessed.
[0162] Interactions between genetic alterations and treatments (alisertib versus placebo) were tested with a Cox proportional hazards model for PFS and OS. The genetic alterations tested included: single gene mutations (mutant allele frequency [MAF] ≥0.01), pathway gene mutations, and mutation load. Pathway gene mutations were categorized based on the 876 MetaCore™ molecular signaling pathways and the status of pathway-level mutation was definedby: 1) counting the number of mutated member genes in a given pathway, and 2) converting the count of mutated genes into a binary variable with ‘mutant’ and ‘wild-type’ variants (i.e., if the count was ≥1, it was ‘mutant’; otherwise, it was ‘wild type’).

[0164] vi. Results
[0165] a. Correlative Analysis of Genetic Alterations in Relation to Clinical Efficacy
[0166] The association between genetic alterations in ctDNA and clinical outcomes (PFS and OS) during treatment with alisertib / paclitaxel was assessed. The correlative analysis of clinical outcomes (PFS and OS) was assessed in relation to individual gene mutations, biological pathway gene mutations, and overall mutation load. PFS and OS were compared between the two treatment arms (alisertib / paclitaxel versus paclitaxel / placebo) with patients categorized based on the presence of mutations termed “mutant.” The mutations identified in a post-hoc analysis are listed in Table 2 and Table 3.
[0167] In patients with SCLC with c-Myc positive and RB1 mutations and in the patients with c-Myc positive and TP53 mutations, the combination of alisertib and paclitaxel gave a very strong statistically significant benefit in PFS and OS and the magnitude of the benefit is much larger than in patients with c-Myc positive alone.
[0168] Patients with c-Myc positive SCLC had median PFS = 4.63 versus 2.27 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.35 [95% CI: 0.16-0.78], p = 0.006. (FIG. 1A). In the same population, median OS = 7.20 versus 4.44 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.27 [95% CI: 0.11-0.70], p = 0.004. (FIG. 1B).
[0169] Patients with RB1 mutant SCLC had median PFS = 3.68 versus 1.84 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.41 [95% CI: 0.25-0.69], p ≤ 0.001. (FIG. 2A). In the same population, median OS = 7.20 versus 4.47 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR= 0.47 [95% CI: 0.28-0.77], p = 0.002. (FIG. 2B).
[0170] Patients with c-Myc positive and RB1 mutant SCLC had median PFS = 5.54 versus 1.99 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.17 [95% CI: 0.05-0.64], p = 0.003. (FIG. 3A). In the same population, median OS = 9.56 versus2.92 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.12 [95% CI: 0.03-0.55], p = 0.002. (FIG. 3B).
[0171] Patients with TP53 mutant SCLC had median PFS = 3.32 versus 2.17 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.60 [95% CI: 0.40-0.89], p = 0.009. (FIG. 4A). In the same population, median OS = 5.98 versus 5.13 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.74 [95% CI: 0.49-1.11], p = 0.139. (FIG. 4B).
[0172] Patients with c-Myc positive and TP53 mutant SCLC had median PFS = 4.63 versus 1.99 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.37 [95% CI: 0.14-0.94], p = 0.027. (FIG. 5A). In the same population, median OS = 9.56 versus 4.21 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.24 [95% CI: 0.08-0.76], p = 0.009. (FIG. 5B).
[0173] Patients with RB1 mutant and TP53 mutant SCLC had median PFS = 3.58 versus 2.10 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.43 [95% CI: 0.25-0.72], p = 0.001. (FIG. 6A). In the same population, median OS = 7.20 versus 4.44 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.48 [95% CI: 0.28-0.80], p = 0.004. (FIG. 6B).
[0174] Patients with RB1 mutant, TP53 mutant and c-Myc positive SCLC had median PFS = 5.54 versus 1.99 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.17 [95% CI: 0.05-0.64], p = 0.003. (FIG. 7A). In the same population, median OS = 9.56 versus 2.92 months in the alisertib / paclitaxel and placebo / paclitaxel arms, respectively (HR = 0.12 [95% CI: 0.03-0.55], p = 0.002. (FIG. 7B).
[0175] The data showed that SCLC patients with c-Myc positive, and / or RB1 mutant, and / or TP53 mutant SCLC showed a benefit from the treatment with alisertib and paclitaxel as compared to placebo / paclitaxel.
