28 mei 2026 bijgewerkt door: Kyowa Kirin Co., Ltd.

A Phase 2, Multicenter, Open-Label Study of Ziftomenib Monotherapy in Japanese Patients With Relapsed or Refractory Acute Myeloid Leukemia With NPM1 Mutation

This is the first study to administer ziftomenib to Japanese patients. In this study, the efficacy, safety, and pharmacokinetics of ziftomenib will be evaluated in patients with relapsed or refractory NPM1-mutated acute myeloid leukemia
