Bezuclastinib Achieves 87% Response Rate in Pivotal Trial for Non-Advanced Systemic Mastocytosis
- Cogent Biosciences' bezuclastinib demonstrated superior symptom improvement with a placebo-adjusted difference of 8.91 points in total symptom score at 24 weeks (p=0.0002) in the SUMMIT trial.
- The drug showed remarkable efficacy on mast cell burden, with 87.4% of patients achieving at least 50% reduction in serum tryptase compared to 0% in the placebo group.
- Bezuclastinib exhibited a favorable safety profile with most adverse events being low-grade, supporting its potential for chronic use in systemic mastocytosis patients.
- The company plans to submit a New Drug Application to the FDA by the end of 2025 based on these positive results from the registration-directed trial.
