Inclusion criteria

* Histologically confirmed diagnosis of NSCLC and homozygous MTAP deletion detected in tumor tissue and willingness to provide archival/fresh samples at screening for central MTAP status confirmation. * Advanced or metastatic NSCLC not amenable to curative therapies after progression on prior therapies at the time of enrollment (based on the American Joint Committee on Cancer, Ninth Edition). * At least 1 measurable lesion as per RECIST v1.1. * Documented radiographic disease progression on or after the most recent line of treatment. * Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. * Participant must be ≥ 18 years of age (or the legal age of consent in the jurisdiction in which the study is taking place) at the time of signing the ICF. * Capability to swallow tablets intact (without chewing or crushing).

Exclusion criteria

* Active brain metastases or carcinomatous meningitis. * History of gastrointestinal disease or other gastrointestinal conditions (eg, uncontrolled nausea, vomiting, malabsorption syndrome) likely to alter absorption of study treatment or result in inability to swallow oral medications. * Prior treatment with a PRMT5 or MAT2A inhibitor. * Known severe hypersensitivity to study treatment and/or any of its excipients. * Other protocol-defined inclusion/

Design outcomes

Primary

MeasureTime frameDescription
Number of participants who achieve Objective Response (OR) utilizing the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1Up to 3 years after the last participant's last dose of study treatmentOR is defined as confirmed complete response (CR) or partial response (PR)

Secondary

MeasureTime frameDescription
Number of participants who achieve disease control (DC) as assessed by RECIST v1.1Up to 3 years after the last participant's last dose of study treatmentDC is defined as Best Overall Response (BOR) of confirmed CR, confirmed PR, or stable disease (SD)
Number of participants who achieve clinical benefit (CB) as assessed by RECIST v1.1Up to 3 years after the last participant's last dose of study treatmentCB is defined as BOR of confirmed CR, confirmed PR, or SD for at least 6 months after start of treatment
Duration of response (DOR) as assessed by RECIST v1.1Up to 3 years after the last participant's last dose of study treatmentDOR is defined as the time between the date of the first documentation of objective tumor response (CR or PR) and the date of disease progression or to death from any cause (whichever occurs first)
Progression-free survival (PFS) as assessed by RECIST v1.1Up to 3 years after the last participant's last dose of study treatmentPFS is defined as the time between randomization and the date of disease progression or death from any cause (whichever occurs first)
Time to objective response (TTOR) as assessed by RECIST v1.1Up to 3 years after the last participant's last dose of study treatmentTTOR is defined as the time between randomization to the date of the first documentation of objective tumor response (CR or PR)
Number of participants with adverse events (AE)Up to 28 days after the last dose of study treatment
Number of participants with Serious AEs (SAEs)Up to 28 days after the last dose of study treatment
Number of participants with AEs leading to dose interruption, reduction, or discontinuationUp to 28 days after the last dose of study treatment
Number of deathsUp to 28 days after the last dose of study treatment
Number of participants who achieve Objective Response (OR) as assessed by RECIST v1.1Up to 3 years after the last participant's last dose of study treatment
Overall Survival (OS)Up to 3 years after the last participant's last dose of study treatmentOS is defined as the time between the randomization/the start of treatment to death due to any cause
Change from baseline in cancer-related symptoms and health-related quality of life as assessed by the Non-small Cell Lung Cancer Symptom Assessment Questionnaire (NSCLC-SAQ) total score and symptom scoreUp to 28 days after the last dose of study treatment
Change from baseline in cancer-related symptoms and health-related quality of life as assessed by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core Function Global Health Status functional scale scoreUp to 28 days after the last dose of study treatment
Change from baseline in cancer-related symptoms and health-related quality of life as assessed by the EORTC-QLQ-F17 quality-of-life (QoL) functional scale scoreUp to 28 days after the last dose of study treatment
