简要总结
This single-armed study aims to investigate the safety and efficacy of sonrotoclax in combination with intensive chemotherapy in subjects with newly diagnosed AML. Subjects will be stratified based on the genetic risk classification of 2022 European LeukemiaNet (ELN) recommendations and MRD status to receive specific consolidation therapy after the induction therapy.
详细描述
47 subjects who meet the eligibility criteria will receive no more than 2 cycles (each cycle is 28 days) of induction therapy with sonrotoclax on day5-14 combined with the standard 3+7 intensive chemotherapy regimen (3+7 regimen) containing cytarabine, and daunorubicin or idarubicin. In cycle(C)1 of induction therapy, sonrotoclax will be administered orally once daily by a 4-day dose rump-up of 20mg on Day(D)5, 40mg on D6, 80mg on D7, and 160mg on D8-14. The first 6 subjects will be enrolled in a Safety Run-in period in C1 to assess tolerability and determine the final sonrotoclax regimen. Within 42 days or before the next cycle of therapy, if ≤1 of 6 subjects has dose-limiting toxicities (DLT), the study will be continued with the sonrotoclax dose regimen as above, and if ≥2 of 6 subjects have DLTs, the dose will be adjusted. Adjustment may include reducing the dose, shortening the duration of each cycle, or terminating the study, based on the DLTs' characteristics.
Subjects who achieve a composite complete remission (CRc) after induction therapy will receive further consolidation therapy, which regimen will be decided based on the ELN risk at diagnosis and MRD status detected by MFC after induction therapy.
After consolidation, subjects will receive once daily sonrotoclax orally combined with azacitidine (AZA) subcutaneously once daily alternating with AZA monotherapy every 2 cycles as maintenance therapy until unacceptable toxicity, 12 months, recurrence, death, withdrawal of informed consent, or study termination determined by investigators.
This single-armed study aims to investigate the safety and efficacy of a risk-stratified regimen of sonrotoclax in combination with intensive chemotherapy in subjects with newly diagnosed AML.

研究组 & 干预措施
Assigned Interventions
Experimental: Sonrotoclax combined with intensive chemotherapy. Subjects receive induction therapy consisting of sonrotoclax combined with a 3+7 regimen. According to the ELN risks and MRD status, subjects who achieve composite complete remission (CRc) proceed with consolidation therapy, and allogeneic hematopoietic stem-cell transplant (allo-HSCT) can be included per investigator's decision.
After the consolidation, subjects will receive sonrotoclax combined with azacitidine (AZA) alternating with AZA monotherapy every 2 cycles as maintenance therapy until intolerable toxicity, 12 months, relapse, death, withdrawal of informed consent, or study termination determined by investigators, whichever occurs first.
