What this trial studies

This study evaluates the mass balance, metabolism, elimination, and drug levels of [14C]-BMS-986504 (MRTX1719) in participants who have advanced solid tumors with a homozygous deletion of the methylthioadenosine phosphorylase (MTAP) gene. It aims to understand how the drug behaves in the body and its potential effectiveness in this specific patient population. Participants must have previously received or been intolerant to standard cancer treatments. The study is interventional and is classified as Phase 1, focusing on the pharmacokinetics of the drug.

Who should consider this trial

Good fit: Ideal candidates are individuals with advanced, unresectable, or metastatic solid tumors that have a homozygous MTAP deletion.

Not a fit: Patients without the homozygous MTAP deletion or those who have not exhausted standard treatment options may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors that have a specific genetic alteration.

How similar studies have performed: While this approach is novel in targeting the MTAP deletion, similar studies have shown promise in evaluating targeted therapies for specific genetic alterations in tumors.
