Pediatric-inspired Regimen Combined With Venetoclax for Adolescent and Adult Patients With de Novo Philadelphia Chromosome-Negative Acute Lymphoblastic Leukemia

Registration Number
NCT05660473
Lead Sponsor
Institute of Hematology & Blood Diseases Hospital, China
Brief Summary

The pediatric-inspired regimen has greatly improved the prognosis of adult patients with with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph- ALL), but relapse remains a great challenge. Venetoclax (Ven) is an oral, selective inhibitor of B-cell lymphoma 2 (Bcl-2). Although this drug is currently used primarily for acute myeloid leukemia, in vitro as well as small cohort studies suggest a effect in acute lymphoblastic leukemia. This study proposes to combine pediatric-inspired regimen with venetoclax for the treatment of adult patients with Ph- ALL, aiming to improve the MRD-negative complete remission rate measured by flow cytometry after induction and to reduce relapse, thus further improving patients overall survival.
