* Severe or unstable cardiac condition within 6 months prior to starting study treatment
* Active, known, or suspected autoimmune disease that has required systemic treatment in the past 2 years
* Known second malignancy either progressing or requiring active treatment within the last 3 years

For both cohorts:

* Prior immune checkpoint inhibitors except in the context of adjuvant or neoadjuvant; Participants who were on control arm of a study with an investigational anti-PD-1/PD-L1 are eligible.
* Received adjuvant or neoadjuvant therapy during the 6 months prior to development of metastatic disease.
* For Cohort A: any prior systemic treatment for advanced/metastatic disease
* For Cohort B: >2 prior lines of any systemic treatment for advanced/metastatic disease
* Inability to undergo any contrast-enhanced radiologic response assessment
