118 participants in 6 patient groups

Telaglenastat 600 mg + Standard Dose Nivolumab
Experimental group
Description:
Telaglenastat 600 mg in combination with standard dose nivolumab in participants with advanced/metastatic clear cell renal cell carcinoma (ccRCC), melanoma, and non-small cell lung cancer (NSCLC).
Treatment:
Drug: CB-839
Drug: Nivolumab
Telaglenastat 800 mg + Standard Dose Nivolumab: ccRCC Naïve to Checkpoint Inhibitors
Experimental group
Description:
Telaglenastat 800 mg/standard dose nivolumab combination in participants with advanced/metastatic ccRCC who have previously received at least one tyrosine kinase inhibitor (TKI) but are treatment naïve to checkpoint modulators programmed death-1/programmed death ligand-1 (PD-1/PD-L1), cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), or any other agent that specifically targets a T-cell checkpoint or co-stimulation pathway.
Treatment:
Drug: CB-839
Drug: Nivolumab
Telaglenastat 800 mg + Standard Dose Nivolumab: ccRCC Recently Treated With Nivolumab
Experimental group
Description:
Telaglenastat 800 mg/standard dose nivolumab combination in participants with advanced/metastatic ccRCC who received nivolumab in most recent treatment line that had documented radiological disease progression OR are currently receiving nivolumab with stable disease for at least 24 weeks.
Treatment:
Drug: CB-839
Drug: Nivolumab
Telaglenastat 800 mg + Standard Dose Nivolumab: ccRCC With Prior PD-1 Therapy
Experimental group
Description:
Telaglenastat 800 mg/standard dose nivolumab combination in participants with advanced/metastatic ccRCC that had documented radiological disease progression while receiving an anti-PD-1/PD-L1 therapy in any prior line of therapy.
Treatment:
Drug: CB-839
Drug: Nivolumab
Telaglenastat 800 mg + Standard Dose Nivolumab: Melanoma With Prior PD-1 Therapy
Experimental group
Description:
Telaglenastat 800 mg/standard dose nivolumab combination in participants with unresectable or metastatic melanoma that had documented radiological disease progression while receiving an anti-PD-1 therapy in their most recent line of therapy.
Treatment:
Drug: CB-839
Drug: Nivolumab
Telaglenastat 800 mg + Standard Dose Nivolumab: NSCLC With Prior PD-1 Therapy
Experimental group
Description:
Telaglenastat 800 mg/standard dose nivolumab combination in participants with NSCLC that does not harbor an activating mutation in the epidermal growth factor receptor (EGFR) oncogene and who received nivolumab in most recent treatment line and had documented radiological disease progression OR are currently receiving nivolumab with Stable Disease for at least 24 weeks.
Treatment:
Drug: CB-839
Drug: Nivolumab
