Avapritinib in Relapsed Refractory or MRD-positive CBF-AML With KIT Mutations
AML with t(8; 21)(q22; q22) or inv(16)(p13; q22)/t(16; 16)(p13; q22) is known as CBF-AML. KIT mutations are common in CBF-AML, which have a worse prognosis.This study is aimed to evaluate the efficacy of Avapritinib, an highly specific inhibitor of the KIT gene, in CBF-AML with KIT mutations.
• Patients with acute myeloid leukemia accompanied by t(8; 21)/RUNX1-RUNX1T1, or inv(16)/t(16; 16)/CBFβ-MYH11;
• Accompanied by KIT mutation
• Disease recurrence after the first remission, or the mol-MRD remains positive after the morphologic remission of AML.
• No active infection.
