Official title
A Phase 1 Study to Evaluate the Safety and Tolerability of GS-5319 Monotherapy and Combination Therapy in Adults With MTAP-deleted Advanced Solid Tumors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical study is to learn more about the study drug, GS-5319, its dosing, safety and tolerability when given as a single medication and as a combined medication in adults with solid tumors, where the participants show a specific gene alteration in the tumor. The gene helps produce methylthioadenosine phosphorylase (MTAP) enzyme. MTAP enzyme helps in normal growth of cells. The primary objectives of the study are to assess the safety and tolerability of GS-5319 as monotherapy and combination therapy in participants with MTAP-deleted advanced solid tumors and identify the maximum tolerated dose (MTD)/maximum administered dose (MAD) and/or the recommended dose(s) for expansion (RDE).
