MRD-associated Non-intensive But Non-interruptive Treatment of Ph-negative Acute Lymphoblastic Leukemia Adult Patients

Summary

Non-intensive But Non-interruptive Treatment based on previously study RALL-2016 of Adult Ph-negative Acute Lymphoblastic Leukemia: No high-dose methotrexate (MTX) and high-dose cytarabine (ARA-C) consolidation blocks, L-asparaginaseis scheduled for 1 year of treatment, 21 intrathecal injections through the whole treament, T-ALL patients in complete remission (CR) with MRD-positive status after 2nd induction receive consolidation 1-3 with venetoclax (56 days), and B-ALL patients in complete remission (CR) with MRD-positive status after 2nd induction receive 1 consolidation with blinatumomab. After that consolidation bone samples are collected and tested for MRD and patients will continue therapy by protocol without HSCT if MRD-negative (by flow cytometry by aberrant immunophenotype in a centralized lab) status was achieved.
