Key Recent Clinical Data
-
INTRIGUE Trial (NCT03740489): Published in the New England Journal of Medicine (2021), demonstrated that ripretinib significantly improved median progression-free survival (mPFS) over sunitinib (6.3 months vs 1.2 months; p<0.001). Overall response rate (ORR) was 9% vs 0%.
-
Real-World Evidence: Post-marketing surveillance indicates improved patient outcomes with manageable adverse events (AEs), primarily alopecia, fatigue, hypertension, and gastrointestinal symptoms.
Ongoing Trials
- Combination Studies: Ripretinib combined with immune checkpoint inhibitors (NCT04676402), targeting synergistic effects in resistant GIST and other KIT-dependent malignancies.
- Expanded Indications: Trials exploring activity in systemic mastocytosis (NCT02957680) and other KIT-driven tumors.
