Individualized Induction Therapy for Non-elderly Acute Myeloid Leukemia Patients With Adverse Risk Features

Phase 2

• Conditions: Acute Myeloid Leukemia, Adult
• Interventions: Drug: venetoclax combined with decitabine

• Registration Number: NCT04752527
• Lead Sponsor: The First Affiliated Hospital of Soochow University

Brief Summary

Individualized induction therapy will be applied to the non-elderly acute myeloid leukemia (AML) patients with adverse genetic risk features guided by rapid screening with fluorescence in situ hybridization (FISH) and next-generation sequencing (NGS), such as the combination of Venetoclax plus decitabine, and Sorafenib for patients with high (FMS)-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) allelic ratio. This study aims to improve induction therapy for non-elderly AML patients with adverse genetic risk features, reduce treatment-related complications, and improve overall survival.

Detailed Description

The non-elderly AML patients who meet the adverse risk group defined as 2017 European LeukemiaNet (ELN) risk stratification, are more likely to be refractory to intensive induction and have low rates of long-term survival. Venetoclax (drug name) plus decitabine or azacitidine showed tolerable safety and favorable overall response rate (ORR )(complete remission (CR)+CR with incomplete hematologic recovery (CRi) rate: 67%) in elderly AML patients. In addition, combination therapy with sorafenib, cytarabine and idarubicin was able to induce a high CR rate in non-elderly AML patients with FLT3 mutations and a 1-year probability of survival of 74%. The fast next-generation sequencing together with FISH can identify the adverse genetic risk features in AML patients within 72 hours. Individualized induction therapy will be applied to the non-elderly AML patients with adverse genetic risk features guided by rapid screening with FISH and NGS, such as the combination of venetoclax plus decitabine, and Sorafenib for patients with high FLT3-ITD allelic ratio. This study aims to improve induction therapy for non-elderly AML patients with adverse genetic risk features, reduce treatment-related complications, and improve overall survival.
