Study Purpose

To determine the amount of telaglenastat that is safe and tolerable when given together with the recommended treatment regimen of pembrolizumab, carboplatin, and pemetrexed and to determine if the combination of standard drugs with telaglenastat is more active against your type of cancer than the standard drugs alone.
