PRIMARY OBJECTIVE: I. To determine the safety and tolerability of glutaminase inhibitor CB-839 hydrochloride (CB-839 HCl) (telaglenastat) in combination with MLN0128 (sapanisertib) and determine the recommended phase 2 dose (RP2D) of the combination.

PRIMARY OBJECTIVE: I. To determine the safety and tolerability of glutaminase inhibitor CB-839 hydrochloride (CB-839 HCl) (telaglenastat) in combination with MLN0128 (sapanisertib) and determine the recommended phase 2 dose (RP2D) of the combination. SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity. II. To examine preliminary efficacy of CB-839 HCl (telaglenastat) and MLN0128 (sapanisertib) in squamous cell lung cancers (LSCC) and in select, molecularly-defined non-small cell lung cancer (NSCLC) cohorts. IIa. To evaluate the objective response rate (ORR), progression-free survival (PFS), and disease control rate (DCR) of patients treated with CB-839 HCl (telaglenastat) and MLN0128 (sapanisertib). EXPLORATORY OBJECTIVES: I. To correlate genomic and metabolomic signatures with response. II. To evaluate metabolic response (18Glutamine [GLN]-positron emission tomography [PET]/computed tomography [CT]; 18Fluorodeoxyglucose [FDG]-PET/CT) in NSCLC tumors treated with CB-839 HCl (telaglenastat) and MLN0128 (sapanisertib) in the dose expansion. OUTLINE: This is a dose-escalation study of glutaminase inhibitor CB-839 hydrochloride. Patients receive glutaminase inhibitor CB-839 hydrochloride orally (PO) twice daily (BID) and sapanisertib PO once daily (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 quarterly.
