What was measured

A DLT was defined as any of the following toxicities assessed by the investigator as possibly, probably, or definitely attributable to carfilzomib, with protocol defined exclusions: Any Grade 4 nonhematologic toxicity, ≥ Grade 4 neutropenia or ≥ Grade 3 thrombocytopenia.

Analysis population: Phase 1b DLT Evaluable Analysis Set: All participants who received all planned dose of carfilzomib and the chemotherapy backbone per protocol during the lead-in window and induction cycle, or received at least one dose of carfilzomib and the chemotherapy backbone per protocol and experienced a DLT prior to completion of the lead-in window or induction cycle, or as clinically indicated.

Groups in this outcome

Phase 1b: Dose Escalation 1 (20 mg/m^2)

Participants with relapsed or refractory ALL received carfilzomib 20 mg/m\^2 in combination with R3 IV for approximately 9 weeks (1-week lead-in window, 28-day induction cycle, and 28-day optional consolidation cycle).

Phase 1b: Dose Escalation 1 (20/27 mg/m^2)

Participants with relapsed or refractory ALL received carfilzomib 20 mg/m\^2 for the first dose, followed by the target 27 mg/m\^2 dose in combination with R3 IV for approximately 9 weeks (1-week lead-in window, 28-day induction cycle, and 28-day optional consolidation cycle).

Phase 1b: Dose Escalation 2 (20/27 mg/m^2)

Participants with relapsed or refractory ALL received carfilzomib 20 mg/m\^2 for the first dose, followed by the target 27 mg/m\^2 dose in combination with VXLD IV for approximately 8 weeks (28-day induction cycle, and 28-day optional consolidation cycle).

Phase 1b: Dose Escalation 2 (20/36 mg/m^2)

Participants with relapsed or refractory ALL received carfilzomib 20 mg/m\^2 for the first dose, followed by the target 36 mg/m\^2 dose in combination with VXLD IV for approximately 8 weeks (28-day induction cycle, and 28-day optional consolidation cycle).

Phase 1b: Dose Escalation 2 (20/45 mg/m^2)

Participants with relapsed or refractory ALL received carfilzomib 20 mg/m\^2 for the first dose, followed by the target 45 mg/m\^2 dose in combination VXLD IV for approximately 8 weeks (28-day induction cycle, and 28-day optional consolidation cycle).

Phase 1b: Dose Escalation 2 (20/56 mg/m^2)

Participants with relapsed or refractory ALL received carfilzomib 20 mg/m\^2 for the first dose, followed by the target 56 mg/m\^2 dose in combination VXLD IV for approximately 8 weeks (28-day induction cycle, and 28-day optional consolidation cycle).
