- 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.
- 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.
- 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.
- 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.
- Overall Survival (OS) [ Time Frame: 36 months ]OS is defined as the time from randomization to death due to any cause.
- Overall Survival (OS) at 6 Months [ Time Frame: 6 months ]OS is defined as the time from randomization to death due to any cause.
- Overall Survival (OS) at 12 Months [ Time Frame: 12 months ]OS is defined as the time from randomization to death due to any cause.

Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Stage IV squamous NSCLC.

- Has study-eligible mutation in NFE2L2 or wild-type NFE2L2 using NGS from a College of American Pathologists- (CAP)-accredited and/or a Clinical Laboratory Improvement Amendments- (CLIA)-certified laboratory
- Must have at least one radiographically measurable lesion per RECIST v1.1 defined as a lesion that is ≥ 10 mm in longest diameter or lymph node that is ≥ 15 mm in short axis imaged by computerized tomography (CT) scan or Magnetic Resonance Imaging (MRI).
- Target lesions situated in a previously irradiated area may be considered measurable if progression has been demonstrated subsequent to radiation therapy.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-1

-
A female patient of childbearing potential must:
- Have a negative serum or urine pregnancy test within 7 days prior to the first dose of study treatment
- Agree to use acceptable methods of contraception(See Section 8.1.2) during the study and for a minimum of 14 days following the last dose of sapanisertib
- Post-menopausal females (no menses for >1 year without an alternative medical cause) and surgically sterilized females are exempt from these requirements.
- Male patients must use an effective barrier method of contraception if sexually active with a female of childbearing potential and refrain from donating sperm during the study and for a minimum of 14 days following the last dose of sapanisertib.
Exclusion Criteria:
- Non-squamous cell histology and mixed histology tumors with any small-cell/neuroendocrine component.
- Prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment per investigator's discretion.
-
Receipt before the first dose of study drug of any of the following:
i. Any investigational agent within 4 weeks. ii. Chemotherapy with 3 weeks (6 weeks for nitrosoureas or mitomycin C) iii. Any radiotherapy within 2 weeks prior to randomization with the exception of palliative radiotherapy for isolated tumor lesions
- Major surgery or other anticancer therapy not previously specified within 4 weeks.
- Unable or unwilling to discontinue proton pump inhibitor (PPI) use ≥ 5 days prior to randomization.
- Interstitial lung disease or a history of pneumonitis that required oral or intravenous glucocorticoid treatment.
- Any condition including social, psychiatric or medical (including uncontrolled significant concurrent illness) that in the opinion of the Investigator could interfere with treatment or protocol-related procedures.
- Patients who are pregnant or lactating.
- Symptomatic ascites or pleural effusion. Exception: Patients who are clinically stable following treatment for these conditions (including therapeutic thoraco-or paracentesis) are eligible.
- Refractory nausea and vomiting, uncontrolled diarrhea, malabsorption, significant small bowel resection or gastric bypass surgery, use of feeding tubes or other situation that may preclude adequate absorption of oral study medication.

- Patients receiving systemic corticosteroids greater than prednisone 10 mg or equivalent (excluding inhalers or low-dose hormone replacement therapy) within the 7 days before treatment initiation.
- Previous intolerance to mammalian target of rapamycin (mTOR), AKT, or dual PI3K/mTOR inhibitors.
- Patients with symptomatic, active/untreated central nervous system metastasis and/or leptomeningeal disease are not eligible.
- Significant active cardiovascular disease
- Participants who are known to be HIV-positive, unless assessed to be healthy with a low risk of AIDS-related outcomes.
- Known active Hepatitis B or C infection.
- Manifestations of malabsorption due to prior gastrointestinal (GI) surgery, GI disease, or for an unknown reason that may alter the absorption of the study drug.
