The objective of this observational study is to evaluate the efficacy and safety of menin inhibitor maintenance therapy in patients with acute leukemia who have undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT).
Eligible patients will receive menin inhibitor maintenance therapy as part of their routine clinical practice. Acceptable agents include, but are not limited to, Revumenib, BN104, Ziftomenib, HMPL-506, or other menin-KMT2A interaction inhibitors. This study imposes no additional interventions on clinical management. The specific menin inhibitor, initiation timing, dose adjustments, and treatment duration are determined at the investigator's discretion based on the patient's individual condition and clinical circumstances.
Patients will enter the follow-up phase upon initiation of menin inhibitor maintenance therapy. Efficacy and safety will be assessed at every cycle during the treatment period. Following the completion of treatment, survival follow-up visits will be conducted every three cycles. The primary endpoint is 2-year relapse-free survival rate since enrollment. The secondary endpoints included overall survival, event-free survival, cumulative incidence of relapse, non relpase related mortality and safety.
