About This Trial

Venetoclax can bind to the BCL-2 protein, thereby initiating the apoptosis program and exerting anti-AML effects. The induction regimen combining venetoclax with hypomethylating agents (HMA) significantly improves the remission rate (over 60%) in elderly unfit AML patients and markedly prolongs survival in those achieving complete remission. Isocitrate dehydrogenase (IDH) 1 and 2 are involved in t…

Venetoclax can bind to the BCL-2 protein, thereby initiating the apoptosis program and exerting anti-AML effects. The induction regimen combining venetoclax with hypomethylating agents (HMA) significantly improves the remission rate (over 60%) in elderly unfit AML patients and markedly prolongs survival in those achieving complete remission. Isocitrate dehydrogenase (IDH) 1 and 2 are involved in the citric acid cycle. Approximately 20% of AML patients carry IDH1 or IDH2 mutations, which lead to the reduction of α-ketoglutarate to 2-hydroxyglutarate (2-HG). 2-HG can cause histone methylation and inhibit TET2 activity, resulting in DNA hypermethylation, thereby affecting gene expression and cell differentiation. IDH mutations are more common in elderly patients and are often associated with cytogenetic abnormalities; they may also co-occur with FLT3-ITD, NPM1, or DNMT3A mutations. Ivosidenib is an IDH1 inhibitor, and previous studies have confirmed its safety and efficacy in AML treatment. According to adult AML treatment guidelines, IDH-mutated patients eligible for intensive chemotherapy may receive IDH inhibitors during induction therapy. Based on the study by Montesinos et al. on the role of ivosidenib and azacitidine in IDH-mutated AML, for patients ineligible for intensive chemotherapy, a new treatment option has been added: IDH1-mutated AML patients may receive ivosidenib (500 mg, days 1-28) combined with azacitidine (75 mg/m²/day for 7 days) in 28-day cycles, or ivosidenib monotherapy. Recent studies have shown that a triple-drug regimen comprising ivosidenib, venetoclax, and azacitidine demonstrates excellent efficacy and safety. In chemotherapy-ineligible patients, the triple regimen achieved a composite complete remission rate (CRc) of 86% and an overall response rate (ORR) of 92%. At a median follow-up of 27.4 months, the 2-year overall survival (OS) was 72%, and the 2-year event-free survival (EFS) was 72%. Therefore, this study aims to conduct a multicenter, single-arm clinical trial to preliminarily evaluate the long-term efficacy of this combination in adult AML.

Inclusion Criteria: 1. Patients who meet AML according to WHO (2022) or AML and MDS/AML defined by ICC standards with IDH1 mutations detected by PCR or second-generation sequencing. 2. Age ≥14 years old, male or female. 3. The physical status assessment (ECOG-PS) of the Eastern Oncology Collaboration group was 0-2 points. 4. Fulfill the requirements of the following laboratory tests (performed within 7 days prior to treatment) : 1. Total bilirubin ≤ 1.5 times the upper limit of normal value (same age); 2.
