Brief Summary
The purpose of Phase 1b of this study is to:
- Asses the safety, tolerability and activity of carfilzomib, alone and in combination with induction chemotherapy, in children with relapsed or refractory acute lymphoblastic leukemia (ALL).
- Determine the maximum tolerated dose (MTD) and to recommend a phase 2 dose of carfilzomib in combination with induction chemotherapy. The purpose of Phase 2 of this study is to compare the rate of complete remission (CR) of carfilzomib in combination with vincristine, dexamethasone, PEG asparaginase, daunorubicin (VXLD) at the end of induction therapy to an appropriate external control.

Outcome Measures
Primary Outcomes (3)
Phase 1b: Number of Participants Who Experienced Treatment-emergent Adverse Events (TEAEs)
An adverse event (AE) is any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. TEAEs are AEs that occurred after the start of study treatment and up to the end of the study or 30 days of the last study treatment, whichever is earlier. Any clinically significant changes in vital signs, electrocardiograms, and clinical laboratory tests that occurred after study treatment administration were recorded as TEAEs. Treatment-related AEs (TRAEs) were TEAEs considered related to at least one study drug by the investigator, including those with unknown relationship. A serious AE (SAE) was defined as any untoward medical occurrence that resulted in death, was immediately life threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, or another medically important serious event.
From first dose up to 30 days after the last dose of study treatment; maximum duration of treatment was 8 weeks
Phase 1b: Number of Participants Who Experienced Dose Limiting Toxicities (DLTs)
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.
Up to approximately 35 days
Phase 2: Percentage of Participants With Complete Remission (CR) After Induction Therapy
CR was defined as: 1. Attainment of M1 bone marrow status (less than 5% blasts in a bone marrow aspirate and at least 200 cells counted) with no evidence of circulating blasts or extramedullary disease. 2. Recovery of peripheral counts: * Absolute neutrophil count (ANC) greater than or equal to 1000/µL * Platelet count greater than or equal to 100000/µL. * Assessed between days 29 and 45 Data was adjusted as inverse probability of treatment weight (IPTW) for the average treatment effect of the treated (IPTW-ATTW).
Up to Day 50 (28-day cycle of induction therapy + recovery window from Day 29 to Day 45 [Day 36 to Day 50 for infants])

Phase 1b: Percentage of Participants Who Achieved a Combined CR and CR Without Platelet Recovery (CRp) at the End of Induction Cycle
Up to approximately Day 29 of Induction Cycle (28-days cycle, assessment on Day 29)
Phase 1b: Percentage of Participants Achieving Minimal Residual Disease (MRD) Status of <10-³ and <10-⁴ Lymphoblasts at the End of Induction Cycle
Up to approximately Day 29 of Induction Cycle (28-days cycle, assessment on Day29)
