Lindsay Rein, MD, and Frederick Lansigan, MD, compare the mechanisms of action and pharmacologic profiles of the investigational agent bezuclastinib (CGT9486) and the previously-approved therapy avapritinib (Ayvakit) in non-advanced systemic mastocytosis. They discuss differences in kinase selectivity, potency, and potential clinical implications. Rein and Lansigan provide context on how these distinctions may translate into efficacy and tolerability considerations.
