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
