Time frame
Up to Day 100 (28-day cycle of induction therapy + recovery window from Day 29 to Day 45 [up to Day 50 for infants] + 28-day cycle of consolidation therapy + + recovery window from Day 29 to Day 45 [up to Day 50 for infants])

What was measured

MRD was defined as the number of leukemia cells that remained in a participant's body after treatment. MRD was measured with NGS.

Analysis population: Phase 2 Consolidation Safety Analysis Set: All participants who started the consolidation cycle and received at least 1 dose of study treatment during the consolidation period.

Groups in this outcome

Phase 2: B-cell (20/56 mg/m^2)

Eligible participants with relapsed or refractory ALL (B-cell, after having received a targeted B-cell therapy) were treated with VXLD plus carfilzomib 20/56 mg/m\^2 for 1 cycle (induction), followed by assessment of treatment response. Participants who did not show progression during induction underwent a bone marrow and extramedullary disease evaluation after completion of induction therapy. Participants without disease progression after induction could at the investigator's discretion, be treated with 1 28-day consolidation cycle of BFM therapy (cyclophosphamide, cytarabine, 6-mercaptopurine, PEG-asparaginase, vincristine), and IT therapy plus carfilzomib.

Phase 2: T-cell (20/56 mg/m^2)

Eligible participants with relapsed or refractory ALL (T-cell) were treated with VXLD plus carfilzomib 20/56 mg/m\^2 for 1 cycle (induction), followed by assessment of treatment response. Participants who did not show progression during induction underwent a bone marrow and extramedullary disease evaluation after completion of induction therapy. Participants without disease progression after induction could at the investigator's discretion, be treated with 1 28-day consolidation cycle of BFM therapy (cyclophosphamide, cytarabine, 6-mercaptopurine, PEG-asparaginase, vincristine), and IT therapy plus carfilzomib.
