Study Description

Brief Summary

This is a nonrandomized study of ruxolitinib in combination with a standard multi-agent chemotherapy regimen for the treatment of B-cell acute lymphoblastic leukemia. Part 1 of the study will optimize the dose of study drug (ruxolitinib) in combination with the chemotherapy regimen. Part 2 will evaluate the efficacy of combination chemotherapy and ruxolitinib at the recommended dose determined in Part 1.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Ruxolitinib in combination with chemotherapy

Drug: Ruxolitinib
In Part 1, ruxolitinib will be administered at a protocol-defined starting dose in combination with chemotherapy, with dose escalation and de-escalation following the rolling 6 study design. The established recommended starting dose will be taken forward into Part 2.

    Outcome Measures

    Primary Outcome Measures

    1. Part 1: Safety/tolerability of ruxolitinib in combination with chemotherapy as measured by adverse events (AEs), vital signs, clinical laboratory tests, and echocardiograms [Part 1: AEs assessed from screening through up to 30 days after the last dose of study drug, expected to be 26 months (females) or 38 months (males)]

    2. Part 2: Efficacy of ruxolitinib in combination with chemotherapy as measured by Event-free survival, defined as the percentage of patients alive without relapse, progression, or death at 3 years from study Day 1 [Part 2: assessed at 3 years]

    Secondary Outcome Measures

    1. Safety and tolerability of the combination treatment for subjects beginning treatment at the recommended dose for Part 2, as assessed by AEs, vital signs, clinical laboratory tests, and echocardiograms [AEs assessed from screening through up to 30 days after the last dose of study treatment, expected to be 26 months (females) or 38 months (males)]
