    In a phase I trial of avapritinib (formerly BLU-285), which targets D816V mutant KIT, for the treatment of advanced systemic mastocytosis, patients experienced rapid and durable disease control. The overall response rate was 72%, and 56% of patients experienced a complete or partial response. No patients discontinued treatment due to adverse events, most of which were mild to moderate in nature.
