- Participants with Gilbert's syndrome will be eligible for the study
CPI-Naïve Participants (Part 1 Cohort A + C):
- Participants must not have received CPI therapy (for example, anti- cytotoxic T-lymphocyte-associated protein 4 [anti-CTLA-4], anti-programmed death-1 [anti-PD-1]/anti-PD-L1) before study enrollment
- Participant must have progressed on at least one previous systemic therapy for advanced or metastatic disease

CPI-Experienced Participants (Part 1 Cohort B and Part III Cohort H):
- Participants must have experienced documented disease progression on or after CPI therapy (investigational or approved)
- The CPI may have been administered as monotherapy or as part of a combination regimen at any time during the anti-cancer treatment before study enrollment
- Participants with suspected or documented disease progression within the first 12 weeks of CPI therapy may not be eligible and require discussion with the Sponsor.Screening tumor assessment should confirm previous progression
- No history of severe immune-related adverse effects from CPI treatment (National Cancer Institute Common Terminology Criteria for AEs [NCI CTCAE] Grade 3 and 4)
CPI-Experienced Participants (Part 1 Cohort D):
- Participants who experienced disease progression during or following treatment with a platinum-containing regimen and a checkpoint inhibitor, given in combination as one line of therapy or as two separate lines of therapy.
- Participants should have experienced disease progression on docetaxel therapy.
Participants with High-Tumor PD-L1 Expression (Part 2 Cohort E) - Participants with a PD-L1 TPS greater than 50%, who have not received any prior systemic therapy for metastatic NSCLC and who must not have any target mutations and/or rearrangements.
