Brief summary
This study evaluates the safety and tolerability of combining venetoclax with Vyxeos (CPX-351) in pediatric and young adult patients with acute leukemia that has come back or not responded to treatment.
Detailed description
This is a single-institution Phase I pilot study designed to test the safety and tolerability of combining venetoclax with Vyxeos (CPX-351, cytarabine and daunorubicin liposome) for the treatment of relapsed/refractory acute leukemia in young patients. Subjects will receive a single course of study therapy consisting of daily, oral or crushed venetoclax at an assigned dose level with a 3-day ramp-up to target dose and Vyxeos administered intravenously at the established dose on Days 1, 3, and 5. In addition to safety and tolerability, the overall response rate to these therapies will be estimated. Pharmacokinetic (PK) analysis will also be conducted to define the drug clearance of venetoclax in this combination.
Interventions
DRUGVyxeos
Vyxeos Dose: daunorubicin 44 mg/m2 and cytarabine 100 mg/m2 administered via intravenous infusion over 90 minutes on Days 1, 3, and 5.
DRUGVenetoclax
Venetoclax Dose: 1. Dose Level 0 - weight based daily dosing for 21 days 2. Dose Level -1 - weight based daily dosing for 14 days 3. Dose Level -2- weight based daily dosing for 10 days 4. Dose Level -3- weight based daily dosing for 7 days
