Study Comparing IDRX-42 and Sunitinib for Treating Gastrointestinal Stromal Tumors After Imatinib Therapy

Sponsor: GlaxoSmithKline

Sponsor score: 60

ClinicalTrials ID:NCT07218926

This clinical trial is testing a new drug, IDRX-42, to see if it is effective and safe for adults with Gastrointestinal Stromal Tumors (GIST) that have spread or cannot be removed by surgery, and who have already been treated with imatinib. The study compares IDRX-42 to another drug called sunitinib.

Patient Parameters

Program Overview

The aim of this study is to determine if a new medication, IDRX-42, is effective in treating adults with Gastrointestinal Stromal Tumors (GIST) compared to the drug sunitinib. This study focuses on patients whose GIST has either spread to other parts of the body or cannot be surgically removed, and who have previously been treated with imatinib. Researchers will evaluate how well IDRX-42 works and its safety for these patients.
