Interventions

  • Tagraxofusp — DRUG
    Tagraxofusp will be administered by intravenous infusion for 3 consecutive days during each 28-day cycle.
  • Venetoclax — DRUG
    Venetoclax will be administered as an oral tablet (400 milligrams \[mg\]) daily, with ramp up in Cycle 1, and should be continued at target dose (400 mg) for the remainder of Cycle 1 and subsequent cycles of 28 days each.
  • Azacitidine — DRUG
    Azacitidine will be administered subcutaneously or by intravenous infusion (75 milligrams/square meter) over 7 days of each 28-day cycle, per institutional guidelines/physician choice.

Study Details

This 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.
