A Real-world Study on the Efficacy and Safety of Menin Inhibitors as Maintenance After Allo-HSCT
A Real-world Study on the Efficacy and Safety of Menin Inhibitors as Maintenance Therapy After Allogeneic Hematopoietic Stem Cell Transplantation
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.

Detaljeret beskrivelse
AML with KMT2A rearrangements are grouped as a high risk subtype. Allogenic hematopoietic stem cell transplantation is the only curative strategy for this subtype. However, patients with KMT2A rearrangements have a high incidence of relapse rates. Menin inhibitors have shown promising remission rates in patients with relpased or refractory patients haboring specific fusions including KMT2A rearrangements. The role of menin inhibitors in post-HSCT maintenance therapy remains unknown.

Beskrivelse
Inclusion Criteria:
- Age ≥ 15 years.
- Patients diagnosed with acute leukemia (including AML, ALL, and MPAL) according to the World Health Organization (WHO 2022) criteria.
- Must meet one of the following characteristics: a. Harboring an NPM1 gene mutation (without concurrent FLT3-ITD or FLT3-TKD mutation); b. Harboring a KMT2A gene rearrangement or KMT2A-PTD; c. Harboring a NUP98 gene rearrangement; d. Other acute leukemia subtypes dependent on the menin-KMT2A interaction, if evidenced, may be enrolled upon discussion with and approval from the principal research team.
- Has undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT), with ≥ 30 days elapsed since the date of graft infusion.
- Received menin inhibitor maintenance therapy after allo-HSCT and meets the following conditions: a. Received at least ≥ 2 complete cycles (7 days per cycle) of menin inhibitor therapy, or cumulative medication duration ≥ 14 days; b. Patient was in a state of CR/CRh/CRi at the initiation of maintenance therapy.
- No evidence of leukemia relapse during menin inhibitor maintenance therapy, defined as: a. Bone marrow blasts < 5%, and blasts do not exhibit morphological features of acute leukemia (e.g.Auer rods); b. No evidence of extramedullary leukemia (e.g. CNS leukemia or myeloid sarcoma).
- The menin inhibitors used include but are not limited to: Revumenib, BN104, Ziftomenib, HMPL-506, or other menin-KMT2A interaction inhibitors.
- Capable of understanding and voluntarily signing the informed consent form.
- Complete clinical data.
Exclusion Criteria:
- Presence of any of the following at the initiation of menin inhibitor maintenance therapy (including within 28 days prior to starting treatment): a. Morphologic relapse in bone marrow (bone marrow blasts ≥ 5%); b. Presence of leukemic cells in peripheral blood.
- Active infection that is deemed uncontrolled by the investigator.
- Severe organ dysfunction, including: a. Hepatic impairment: ALT or AST ≥ 5 × ULN (Upper Limit of Normal), or total bilirubin ≥ 3 × ULN; b. Severe renal impairment: eGFR < 30 ml/min/1.73 m²; c. Cardiac dysfunction: NYHA (New York Heart Association) Class III-IV.
- Concurrent acute graft-versus-host disease (aGVHD) ≥ Grade 2 or chronic graft-versus-host disease (cGVHD) ≥ Grade 3, requiring corticosteroids ≥ 1 mg/kg and ≥ 3 types of immunosuppressive therapy (including CNI, ruxolitinib, belumosudil, etc.).
- History of other malignancies requiring ongoing treatment (except for malignancies that have undergone curative treatment or are assessed to be in complete remission and require no systemic maintenance therapy or radiotherapy).
