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.
