Brief Summary:
This is a multicenter, randomized, open-label Phase 2 study of sapanisertib in biomarker-defined populations of sqNSCLC. Patients with NFE2L2 (the name for gene encoding the protein called NRF2)-mutated or wild-type sqNSCLC should have disease that has progressed on or after at least two prior systemic therapies for metastatic disease including platinum-doublet chemotherapy and a programmed cell death 1 ligand 1 (PD-L1) inhibitor. The study will evaluate sapanisertib monotherapy in patients with relapsed/refractory sqNSCLC as two separate groups: Group A: NFE2L2-mutated sqNSCLC and Group B: NFE2L2-WT sqNSCLC.

Condition or disease Intervention/treatment Phase
Non-Small Cell Lung Cancer Squamous Non-small-cell Lung Cancer Squamous Non-Small Cell Neoplasm of Lung NFE2L2 Gene Mutation Drug: sapanisertib Phase 2

Detailed Description:
NFE2L2 mutation status for all patients will be identified using local or central next generation sequencing (NGS) testing on archival or fresh tissue or circulating tumor deoxyribonucleic acid (ctDNA), the results of which must be reviewed and approved by the Sponsor prior to enrollment. Each group will be randomized 1:1 to one of two doses/schedules of sapanisertib. Approximately 30 NFE2L2-mutant and 20 NFE2L2-wild type patients will be enrolled. Patients will be treated with sapanisertib until disease progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1), unacceptable toxicity, withdrawal of consent, or death.

Primary Outcome Measures :
  1. Investigator-Assessed Overall Response Rate (ORR) per RECIST v1.1. [ Time Frame: 36 months ]
    ORR is defined as the percentage of participants with complete response (CR) or partial response (PR) according to the RECIST v1.1 criteria as assessed by the investigator.

  2. Number of Participants With Adverse Events (AEs), Serious AEs, Deaths, and Discontinuations Due to AEs [ Time Frame: after the first dose of study drug through 28 days after the last dose of sapanisertib (up to 36 months) ]
    An adverse event (AE) is any untoward, undesired, or unplanned medical occurrence in a patient administered a medicinal product whether or not considered drug related. A serious adverse event (SAE) is an AE that occurs after receiving study treatment (or after signing informed consent and before receiving study treatment if due to a protocol-mandated procedure) that either results in death, is life-threatening, requires inpatient hospitalization, results in persistent or significant disability, results in congenital anomaly or birth defect, or otherwise meets criteria as an important medical event.

Secondary Outcome Measures :
  1. Duration of Response (DOR) [ Time Frame: 36 months ]
    DOR will be calculated as the time between the first documentation of partial response (PR) or a complete response (CR) to the first documentation of progressive disease or death, whichever occurs first.

  2. Progression-Free Survival (PFS) [ Time Frame: 36 months ]
    PFS is defined as the time from randomization to the first occurrence of disease progression as determined by the investigator using RECIST v1.1 or death from any cause, whichever occurs first.

  3. Overall Survival (OS) [ Time Frame: 36 months ]
    OS is defined as the time from randomization to death due to any cause.

  4. Overall Survival (OS) at 6 Months [ Time Frame: 6 months ]
    OS is defined as the time from randomization to death due to any cause.

  5. Overall Survival (OS) at 12 Months [ Time Frame: 12 months ]
    OS is defined as the time from randomization to death due to any cause.
