Inclusion criteria

* Participants must have Metastatic (Stage IV or recurrent) non-small cell lung cancer (NSCLC) (as defined by the American Joint Committee on Cancer, Ninth Edition) with no prior systemic anti-cancer therapy for metastatic disease. * Participants must have histologically confirmed diagnosis of NSCLC and homozygous methylthioadenosine phosphorylase (MTAP) deletion or MTAP loss. * Participants must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. * Participants must have at least 1 measurable lesion as per RECIST v1.1.

Exclusion criteria

* Nonsquamous participants must not have documented targetable oncogenic mutation or actionable genetic alterations (AGAs) for which there is a standard of care (SoC) available as first-line (1L) therapy. * Participants must not have symptomatic brain metastases or spinal cord compression. * Participants must not have any prior systemic therapy (chemotherapy, immunotherapy, targeted therapy, or biological therapy) for metastatic non-small cell lung cancer (mNSCLC). Note: One cycle of SoC treatment prior to randomization will be allowed for participants who require immediate treatment if clinically indicated. * Participants must not have any known or suspected impairment of gastrointestinal function that may prohibit the ability to absorb or swallow an oral medication without chewing or crushing. * Other protocol-defined Inclusion/
