Overview
Brief Summary
The study aims to determine maximum tolerated dose (MTD) or recommended combination dose of the MTA-cooperative PRMT5 inhibitor Anvumetostat administered in combination with other therapies in adult participants with metastatic or locally advanced methylthioadenosine phosphorylase (MTAP)-deleted thoracic tumors. The study also aims to determine the safety profile of Anvumetostat administered in combination with other therapies in adult participants with metastatic or locally advanced MTAP-deleted thoracic tumors.

Outcomes
Primary Outcomes
Number of Participants Experiencing Serious Adverse Events (SAE)
Time Frame: Up to approximately 3 years
An SAE is defined as any AE that results in death, is life threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital abnormality/birth defect or important medical events that do not meet the preceding criteria but based on appropriate medical judgment may jeopardize the participant or may require medical or surgical intervention to prevent any of the outcomes listed above.
Number of Participants Experiencing Dose Limiting Toxicities (DLT)
Time Frame: Up to approximately 21 days
Number of Participants Experiencing Treatment Emergent Adverse Events (TEAE)
Time Frame: Up to approximately 3 years
TEAEs are any event that occurred after the participant received study treatment. Any clinically significant changes in vital signs, electrocardiograms, and clinical laboratory tests that occurred after study treatment administration were recorded as TEAEs. A serious TEAE is any untoward medical occurrence in a clinical study participant after first dose irrespective of a causal relationship with the study treatment(s) that resulted in death, was immediately life threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, or another medically important serious event.
