Sapanisertib, Carboplatin, and Paclitaxel in Treating Patients With Recurrent or Refractory Malignant Solid Tumors

PRIMARY OBJECTIVE:

I. To determine the safety and tolerability of the combination of sapanisertib (TAK-228 [MLN0128]) plus paclitaxel, when given with carboplatin, and to determine the optimal dose triplet, or maximum tolerated dose (MTD), in patients with advanced cancers refractory to standard therapy.

SECONDARY OBJECTIVES:

I. To assess the clinical tumor response of this combination. II. To assess toxicity of this combination. III. To assess progression free survival. IV. To assess molecular signatures predictive of sensitivity and resistance.

OUTLINE: This is a dose escalation study.

Patients receive sapanisertib orally (PO) once daily (QD) on days 2-4, 9-11, and 16-18, paclitaxel intravenously (IV) over 3 hours on days 1, 8, and 15, and carboplatin IV over 60 minutes on day 1. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive sapanisertib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

Inclusion criteria

Female and male condoms should not be used together.)
• Male patients, even if surgically sterilized (i.e., status post-vasectomy), who: agree to practice highly effective barrier contraception during the entire study treatment period and through 120 days after the last dose of study drug, OR agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods for the female partner], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.) Agree not to donate sperm during the course of this study or within 120 days after receiving their last dose of study drug.

• Total bilirubin =< 1.5 x upper limit of normal (ULN).
• Transaminases (aspartate aminotransferase/serum glutamic oxaloacetic transaminase [AST/SGOT] and alanine aminotransferase/serum glutamic pyruvic transaminase [ALT/SGPT]) =< 2.5 x ULN (=< 5 x ULN if liver metastases are present).
• Creatinine clearance >= 50 mL/min based either on Cockcroft-Gault estimate or based on urine collection (12 or 24 hour).
• Glycosylated hemoglobin (HbA1c) < 7%.
• Fasting serum glucose =< 130 mg/dL.
• Fasting triglycerides =< 300 mg/dL.
• Ability to swallow oral medications.
• Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
• Patients who have a history of brain metastasis are eligible for the study provided that all the following criteria are met: a) Brain metastases which have been treated b) No evidence of disease progression for >= 3 months before the first dose of study drug. c) No hemorrhage after treatment d) Off-treatment with dexamethasone for 4 weeks before administration of the first dose of TAK-228 e) No ongoing requirement for dexamethasone or anti-epileptic drugs.
• Patients must have evaluable or measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
• Patients must be 4 weeks beyond previous treatment of any chemotherapy or radiotherapy, and must have recovered to =< grade 1 or previous baseline for each toxicity. Exception: Patients may have received palliative low dose radiotherapy to the limbs 1-4 weeks before this therapy provided pelvis, sternum, scapulae, vertebrae, or skull were not included in the radiotherapy field. Patients who have received non-chemotherapeutic biological agents will need to wait at least 5 half-lives or 4 weeks, whichever is shorter, from the last day of treatment of non-chemotherapeutic biological agents.

Exclusion criteria

• Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
• Diagnosed or treated for another malignancy within 2 years before administration of the first dose of study drug, or previously diagnosed with another malignancy and have any evidence of residual disease.
