This research study is a non-randomized, open-label Phase Ib clinical trial evaluating venetoclax (Ven) administered orally daily in combination with pegcrisantaspase (PegC) administered IV biweekly, as part of a 28-day treatment cycle in adult subjects with relapsed or refractory acute myeloid leukemia (R/R AML).~The trial will consist of dose escalation to evaluate the safety and tolerability of Ven-PegC and estimate the maximum tolerated doses (MTDs) and/or biologically active doses (e.g. recommended phase 2 doses [RP2Ds]) of Ven-PegC in patients with R/R AML~Venetoclax is an FDA (the U.S. Food and Drug Administration) approved drug, but this combination ( Ven-PegC) has not been approved by the FDA.
Evaluate the safety and tolerability of pegcrisantaspase in combination with venetoclax (Ven-PegC) and estimate the maximum tolerated doses and/or biologically active doses of Ven-PegC in patients with relapsed or refractory acute myeloid leukemia (R/R AML)
