A Study of JNJ-86974680 in Participants With Advanced Non-small Cell Lung Cancer

Inclusion Criteria:

- Individuals with histologically or cytologically confirmed stage IIIB-IV non-small cell lung cancer (NSCLC)

- Part 1: NSCLC with a known actionable genetic mutation (for example, epidermal growth factor receptor [EGFR], anaplastic lymphoma kinase [ALK], c-ros oncogene 1 [ROS1], v-raf murine sarcoma viral oncogene homolog B1 [BRAF]) must have received all approved targeted therapies and have progressed

- Part 2: No targetable mutations (for example, EGFR [epidermal growth factor receptor], ALK [anaplastic lymphoma kinase], ROS1[c-ros oncogene 1], and BRAF [B-Raf proto-oncogene, serine/threonine kinase])

- Part 1 and Cohort A of part 2: Must have been treated with (a) anti-programmed death protein 1 (anti-PD-1) or programmed cell death ligand 1 (PD-L1) therapy and (b) platinum-based chemotherapy

- For Cohort B of Part 2: Previously treated with anti-PD-1/PD-L1 therapy for metastatic disease as the prior line of therapy

- For Cohort C of Part 2: Treatment naïve

- Adequate organ function

Exclusion Criteria:

- Active central nervous system (CNS) disease involvement

- Active autoimmune disease

- Active infection

- History of solid organ or hematologic stem cell transplantation
