Treatment for Ph-negative ALL for Adults up to 65 Years

Overview

The goal of this trial is to provide a protocol for treatment for adults with Ph-negative acute lymphoblastic leukemia (ALL) and to learn if this provides higher probability of survival than the previous one. The main question is to know if the incorporation of blinatumomab for B-cell precursor ALL, substituting some chemotherapy blocks, offers better probability of survival than the previous trial, which did not use immunotherapy. In addition, T-cell precursor ALL participants will receive different treatment approaches depending on the stage of maturation of the tumor.

Participants will be uniformly treated with four drug-induction: vincristine (VCR), prednisone (PDN), pegylated asparaginase (PegASP), daunorubicin (DNR). Resistant participants will receive a second induction with inotuzumab for B-cell precursor ALL or with FLAG-Ida (fludarabine, cytarabine, idarubicin and granulocyte colony stimulating factor) for T-cell precursor ALL. B-cell precursor ALL participants with adequate MRD clearance after cycle 1 of blinatumomab will receive 3 blocks of early consolidation. If adequate MRD clearance and good genetic background, the patients will proceed to delayed intensification, reinduction and maintenance. The remaining patients will receive early or delayed alloHSCT. T-cell precursor ALL participants with adequate MRD clearance after the first cycle of consolidation will receive 2 blocks of early consolidation and reinduction. If adequate MRD clearance and good genetic background, the patients will proceed to delayed intensification and maintenance. The remaining patients will receive early or delayed alloHSCT.
