* At least one site of measurable disease by RECIST 1.1
* Arm 5: Received at least one prior line of therapy, but no more than three prior lines of therapy, for incurable (i.e. unresectable) or metastatic NSCLC. Up to one prior line of FDA-approved checkpoint inhibitor therapy is permitted (must have received at least 4 months of treatment) --OR--
* Arm 6: Received front line immunotherapy (with or without chemotherapy) for incurable or metastatic NSCLC and did not progress clinically or radiographically per RECIST 1.1 at the most recent imaging assessment, and will begin maintenance immunotherapy with standard of care pembrolizumab ± pemetrexed.
* Life expectancy ≥18 weeks
* Arm 5: Disease progression at study entry --OR--
* Arm 6: Documented Stable Disease, Partial Response, Complete Response (SD/PR/CR) per RECIST 1.1 after a minimum of 9 to 12 weeks of front line immunotherapy (with or without chemotherapy).
* Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1
* Central nervous system (CNS) metastases may be permitted but must be treated and neurologically stable
