Brief Summary:
The primary purpose of this study is to determine if sapanisertib in combination with weekly paclitaxel improves progression-free survival (PFS) compared to weekly paclitaxel alone.

Condition or disease Intervention/treatment Phase
Endometrial Neoplasms Drug: Paclitaxel Drug: Sapanisertib Drug: MLN1117 Phase 2

Detailed Description:

The drugs being evaluated in this study are sapanisertib and MLN1117. Sapanisertib is being evaluated as a single agent and in combination with paclitaxel or MLN1117 to treat women with advanced, recurrent, or persistent endometrial cancer. This study will evaluate the efficacy and safety of each drug or drug combination.

The study will enroll approximately 241 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of 4 treatment groups:

  • Paclitaxel 80 mg/m^2
  • Paclitaxel 80 mg/m^2 + Sapanisertib 4 mg
  • Sapanisertib 30 mg
  • Sapanisertib 4 mg + MLN1117 200 mg

Participants will receive either paclitaxel intravenous (IV) weekly, Paclitaxel IV along with sapanisertib orally, sapanisertib orally, or sapanisertib and MLN1117 orally.

This is a multicenter, multinational trial. Participants will make multiple visits to the clinic, with an end of treatment visit (EOT) which will occur 30 to 40 days after receiving their last dose of study drug or before the start of any subsequent anticancer therapy. After EOT, participants will be followed for PFS and overall survival (OS).

Primary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Up to 30 months ]
    PFS is defined as the time in months from the date of randomization to the date of first documentation of progressive disease (PD) or death due to any cause, whichever occurs first. Per RECIST v1.1, PD was defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.


Secondary Outcome Measures :
  1. Number of Participants Who Experienced at Least One Treatment-emergent Adverse Event (TEAE) [ Time Frame: From the first dose of study drug through 30 days after the last dose of study drug (Up to 31 months) ]
    An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. A TEAE is defined as an adverse event with an onset that occurs after receiving study drug.

  2. Overall Survival (OS) [ Time Frame: Up to 36 months ]
    OS is defined as the time in months from the date of randomization to the date of death.

  3. Time to Tumor Progression (TTP) [ Time Frame: Up to 30 months ]
    TTP is defined as the time in months from the date of randomization to the date of first documentation of progression. Per RECIST 1.1, PD was defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

  4. Overall Response Rate (ORR) [ Time Frame: Up to 30 months ]
    ORR is defined as the percentage of participants who achieved a best response of a complete response (CR) or partial response (PR). Per RECIST v1.1, CR was defined as disappearance of all target lesions, non-target lesions, no new lesions, and normalization of tumor marker level. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesions.

  5. Clinical Benefit Rate (CBR) [ Time Frame: Up to 30 months ]
    CBR is defined as the percentage of participants with CR or PR or SD (SD of any duration). Per RECIST v1.1, CR was defined as disappearance of all target lesions, non-target lesions, no new lesions, and normalization of tumor marker level. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesions. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD was defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

  6. Clinical Benefit Rate (CBR) at Week 16 (CBR-16) [ Time Frame: Week 16 ]
    CBR-16 is defined as the percentage of participants who achieved CR or PR of any duration or have SD with a duration of at least 16 weeks. Per RECIST v1.1, CR was defined as disappearance of all target lesions, non-target lesions, no new lesions, and normalization of tumor marker level. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesions. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD was defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

Criteria

Inclusion Criteria:

Prior treatment may include chemotherapy, chemotherapy/radiation therapy, and/or consolidation/maintenance therapy. Chemotherapy administered in conjunction with primary radiation as a radio-sensitized therapy will be considered a systemic chemotherapy regimen.
  4. Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, defined as at least 1 lesion that can be accurately measured in at least 1 dimension (longest diameter to be recorded). Each lesion must be greater than or equal to (>=) 10 millimeter (mm) in long axis when measured by computed tomography (CT), magnetic resonance imaging (MRI), or caliper measurement by clinical exam. Lymph nodes must be >= 15 mm in short axis when measured by CT or MRI.
  5. Tumor accessible and participant consents to undergo fresh tumor biopsies.
  6. Female participants 18 years or older.
  7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
  8. Female participants 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 highly 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 [example, United States Prescribing Information (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 participant. (Periodic abstinence [example, calendar, ovulation, symptothermal, postovulation methods], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception.
