Efficacy/Safety of CPI-613 in Combination With HD Cyt. and Mito. vs HD Cyt. and Mito. in Older Patients With R/R AML

Phase 3 Multicenter Randomized Trial to Evaluate Efficacy and Safety of CPI-613 in Combination With HD Cyt. and Mito. vs HD Cyt. and Mito. Therapy and Control Sub-groups in Older Patients With R/R AML

A Phase III study to evaluate the safety and efficacy of CPI-613® (devimistat) in combination with High Dose Cytarabine and Mitoxantrone in comparison with high dose Cytarabine and Mitoxantrone and control sub-groups: combination of Mitoxantrone, Etoposide and Cytarabine (MEC) and combination of Fludarabine, Cytarabine, and Filgrastim (FLAG) in older patients with relapsed/refractory Acute Myeloid Leukemia. CPI-613® (devimistat) targets the altered energy metabolism and processes for production of ATP and essential bio-intermediates unique to and characteristic of most cancer cell types. The addition of CPI-613® (devimistat) to high dose cytarabine and mitoxantrone (CHAM) will improve the complete remission (CR) rate in patients 50 years or older with relapsed or refractory AML when compared to HAM alone or other control sub groups.

Study Overview

• Status: Terminated
• Conditions: Relapsed/Refractory Acute Myeloid Leukemia
• Intervention / Treatment: Drug: CPI-613 + High Dose Cytarabine and Mitoxantrone; Drug: High Dose Cytarabine and Mitoxantrone; Drug: Mitoxantrone, Etoposide and Cytarabine; Drug: Fludarabine, Cytarabine, Filgrastim

Detailed Description

Subjects were randomized in 1:1 allocation ratio by IWRS according to the stratification factors. However, the control sub-groups (MEC and FLAG) were capped at 100 (50 per sub-group).

Subjects in both Arm 1 and Arm 2 were planned to receive induction cycle 1 treatment for at least 14 days. Subjects will receive follow-up therapy based on results of the bone marrow aspirate, and CR/complete remission with incomplete recovery (CRi) status.
