RecruitingPhase 2Drug trialStudy of SA+X in the Treatment of Newly Diagnosed AMLThis is a phase II, open-label, multi-center study evaluating the efficacy and safety of sonrotoclax (SA) in combination with azacitidine (AZA) plus individualized targeted or chemotherapeutic agents in adult participants with newly diagnosed acute myeloid leukemia (AML). Eligible participants will be stratified into different treatment arms based on genetic background (FLT3/IDH1 mutation status) and fitness for intensive chemotherapy. All participants will receive sonrotoclax with dose escalation from 20 mg/day to 320 mg/day, followed by maintenance dosing, which may be temporarily held by the investigator from Day 14 to Day 28 of each 28-day cycle based on the participant's condition, combined with azacitidine 75 mg/m²/day intravenously on Days 1-7. For participants fit for intensive chemotherapy, additional anthracycline (daunorubicin 60 mg/m²/day or idarubicin 10 mg/m²/day on Days 1-3) will be administered. For participants with FLT3 mutations, gilteritinib 80 mg once daily on Days 1-14 will be added; for those with IDH1 mutations, ivosidenib 500 mg once daily on Days 1-28 will be added.
