New hope for drug-resistant GIST: combo therapy targets stubborn tumors

NCT ID NCT06208748

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a new two-drug combination (bezuclastinib plus sunitinib) in 40 adults with advanced gastrointestinal stromal tumors (GIST) that grew while on sunitinib alone. The goal is to see if the combo can slow cancer progression and understand why some tumors resist treatment. Participants must have a specific KIT mutation and be in fair health.
