|Leptomeningeal Neoplasm Metastatic Lung Carcinoma Metastatic Malignant Neoplasm in the Brain Recurrent Lung Non-Small Cell Carcinoma Stage IV Lung Cancer AJCC v8 Stage IVA Lung Cancer AJCC v8 Stage IVB Lung Cancer AJCC v8||Drug: Glutaminase Inhibitor CB-839 Hydrochloride Drug: Sapanisertib||Phase 1|
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.
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).
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.

Experimental: Treatment (CB-839 HCl, sapanisertib)
Patients receive glutaminase inhibitor CB-839 hydrochloride PO BID and sapanisertib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Drug: Glutaminase Inhibitor CB-839 Hydrochloride
Other Name: CB-839 HCl
- Maximum tolerated dose/recommended phase II dose of MLN0128 (sapanisertib) and CB-839 HCl (telaglenastat) in combination (dose-escalation) [ Time Frame: Up to 28 days ]Will be evaluated according to dose-limiting toxicities during cycle 1 graded using National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.
- Response rate (dose-expansion) [ Time Frame: Up to 27 months ]Response rate will be calculated for each cohort along with an exact 95% confidence interval.
- Median progression free survival (PFS) (dose-expansion) [ Time Frame: Up to 27 months ]Median PFS will be determined using the Kaplan-Meier method individual for each cohort and for all patients as well.
- Objective response rate (ORR) [ Time Frame: Up to 27 months ]ORR will be assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
- PFS [ Time Frame: Up to 27 months ]Will be evaluated by Kaplan-Meier estimates.
- Disease control rate (DCR) [ Time Frame: Up to 27 months ]DCR will be assessed by RECIST 1.1 criteria.
- Metabolic response (18Glutamine [GLN]-positron emission tomography [PET]/computed tomography [CT]; 18Fluorodeoxyglucose [FDG]-PET/CT) [ Time Frame: Up to 27 months ]Change in tumor uptake of radio-labelled glutamine on PET from baseline to cycle 1 day 8 will be quantified by the standardized uptake value maximum (SUVmax) (a standard PET parameter) in the largest measurable lesion. The before and after 18F-Gln PET values will be compared using log(after/before) as a measure of relative change.
- Genomic and metabolic signatures [ Time Frame: Up to 27 months ]Genomic and metabolic signatures will be correlated with responses. Changes in glutamine, glutamate, aspartate, and asparagine will be measured, and responders will be compared to non-responders using a two-sample t-test or Wilcoxon test.
