A phase 1 study of the amino acid modulator pegcrisantaspase and venetoclax for relapsed or refractory acute myeloid leukemia.

Abstract

Glutamine dependency has been shown to be a metabolic vulnerability in acute myeloid leukemia (AML). Prior studies using several in vivo AML models showed that depletion of plasma glutamine, induced by long-acting crisantaspase (pegcrisantaspase [PegC]) was synergistic with the B-cell lymphoma-2 (BCL-2) inhibitor venetoclax (Ven), resulting in significantly reduced leukemia burden and enhanced survival. Here, we report a phase 1 study of the combination of Ven and PegC (VenPegC) for treating adult patients with relapsed or refractory AML, including patients who had previously received Ven. The primary end points were the incidence of regimen-limiting toxicities (RLTs) and the maximum tolerated dose (MTD). Twenty-five patients received at least 1 PegC dose with Ven, and 18
