Overview

Drug evaluation reveals improved progression-free survival with bezuclastinib plus sunitinib in gastrointestinal stromal tumors, highlighting an effective second-line combination strategy.

Key Points

To evaluate the pharmacology, clinical efficacy, safety, and therapeutic potential of bezuclastinib, particularly when combined with sunitinib, for advanced gastrointestinal stromal tumors.
Reviewed preclinical activity, pharmacokinetics, and clinical trial data from PubMed, ClinicalTrials.gov, regulatory sources, and congress proceedings searched through August 13, 2026.
Evaluated clinical efficacy and safety endpoints from the PEAK trial comparing bezuclastinib plus sunitinib against sunitinib alone in patients with advanced KIT-driven disease.
In the PEAK trial, bezuclastinib plus sunitinib extended median progression-free survival to 16.5 months compared to 9.2 months with sunitinib monotherapy.
The combination regimen increased the objective response rate from 25.8% to 45.6% in patients with advanced disease.
Clinical improvements were accompanied by an increased incidence of grade 3 or higher toxicities and a higher frequency of treatment modifications.
