Phase I/II Study of Azacitidine (AZA) with Venetoclax (VEN) and Magrolimab (Magro) in Patients (pts) with Newly Diagnosed Older/Unfit or High-Risk Acute Myeloid Leukemia (AML) and Relapsed/Refractory (R/R) AML

Introduction: In spite of frontline response rates of 65-70% with AZA-VEN a majority of pts relapse, with only 35-40% alive at 3+ years. Outcomes in R/R AML are poor with median overall survival (mOS) 5 - 7months (m). Magro, an anti-CD47 antibody that blocks the "don't eat me signal" on macrophages, demonstrated efficacy with AZA in ND TP53wt (ORR: 63%, mOS 18.9m) and TP53mut AML (ORR 69%, mOS 12.9m). Combined blockade of CD47-SIRPa axis by...
