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

Trial Status: Active

This phase I trial studies the sides effects and best dose of sapanisertib, carboplatin, and paclitaxel in treating patients with malignant solid tumors that have come back (recurrent) or do not respond to treatment (refractory). Sapanisertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing cells, by stopping them from dividing, or by stopping them from spreading. Giving sapanisertib, carboplatin, and paclitaxel may work better in treating patients with malignant solid tumors.

Inclusion Criteria

  • Patients must have a diagnosis of a solid tumor malignancy and is refractory to standard therapies who have relapsed after standard therapy, or whose cancers have no standard therapy.
  • Eastern Cooperative Oncology Group (ECOG) performance status and/or other performance status =< 1.
  • Female patients who: Are postmenopausal for at least 1 year before the screening visit, OR are surgically sterile, OR if they are of childbearing potential, agree to practice 1 effective method of contraception and 1 additional effective (barrier) method, at the same time, from the time of signing the informed consent through 90 days (or longer as mandated by local labeling [e.g., United Surgical Partners International (USPI), summary of product characteristics (SmPC), etc,]) 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], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. 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.

  • 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

  • Carboplatin or paclitaxel exposure within past 6 months.
  • Central nervous system (CNS) metastasis.
  • Other clinically significant co-morbidities, such as uncontrolled pulmonary disease, active central nervous system disease, active infection, or any other condition that could compromise the patient’s participation in the study.
  • Known history of human immunodeficiency virus infection.
  • Known history of hepatitis B surface antigen-positive, or known or suspected active hepatitis C infection.
  • 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. Patients with non-melanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection.
  • Breast feeding or pregnant.
  • Treatment with any investigational products within 4 weeks before the first dose of study drug.
  • Previous treatment with dual PI3K/mTOR inhibitors, TORC1/2 inhibitors or TORC1 inhibitors.
  • Manifestations of malabsorption due to prior gastrointestinal (GI) surgery, GI disease, or for an unknown reason that may alter the absorption of TAK-228. In addition, patients with enteric stomata are also excluded.
  • History of any of the following within the last 6 months before administration of the first dose of the drug: a) Ischemic myocardial event, including angina requiring therapy and artery revascularization procedures b) Ischemic cerebrovascular event, including transient ischemic attack and artery revascularization procedures c) Requirement for inotropic support (excluding digoxin) or serious (uncontrolled) cardiac arrhythmia (including atrial flutter/fibrillation, ventricular fibrillation or ventricular tachycardia) d) Placement of a pacemaker for control of rhythm e) New York Heart Association (NYHA) class III or IV heart failure f) Pulmonary embolism.
  • Significant active cardiovascular or pulmonary disease including: a) Uncontrolled hypertension (i.e., systolic blood pressure > 150 mm Hg, diastolic blood pressure > 90 mm Hg). Use of anti-hypertensive agents to control hypertension before cycle 1 day 1 is allowed. b) Pulmonary hypertension c) Uncontrolled asthma or oxygen (O2) saturation < 90% by arterial blood gas analysis or pulse oximetry on room air d) Significant valvular disease; severe regurgitation or stenosis by imaging independent of symptom control with medical intervention, or history of valve replacement e) Medically significant (symptomatic) bradycardia f) History of arrhythmia requiring an implantable cardiac defibrillator g) Baseline prolongation of the rate-corrected QT interval (QTc) (e.g., repeated demonstration of QTc interval > 480 milliseconds, or history of congenital long QT syndrome, or torsades de pointes).

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.
