A Study of Tagraxofusp in Combination With Venetoclax and Azacitidine in Adults With Untreated CD123+ Acute Myeloid Leukemia Who Cannot Undergo Intensive Chemotherapy

Is NCT06456463 recruiting? Yes, currently enrolling (Jun 2026). This Phase 2 trial studies multiple treatments including Tagraxofusp and Venetoclax for acute myeloid leukemia.

Phase 2RecruitingStemline Therapeutics, Inc.NCT06456463Data as of Jun 2026Location: United States · Australia

Treatment: Tagraxofusp · Venetoclax · AzacitidineThis study will be divided into 2 parts (Part 1 and Part 2). Part 1 will evaluate 2 doses of tagraxofusp (9 and 12 micrograms/kilogram/day \[μg/kg/day\]), used in combination with venetoclax and azacitidine, to determine the dose for Part 2. This determined dose, in combination with venetoclax and azacitidine, will then be further evaluated in Part 2 in 2 cohorts (TP53 mutated and TP53 wild type). Both parts will be conducted in participants with previously untreated CD123+ AML who are ineligible for intensive chemotherapy.
