Trial design

Randomised, open-label, two arms: vac (cusatuzumab 20 mg/kg iv on day 3 and day 17 of the 28-day cycle in combination with venetoclax and azacitidine 75 mg/m2 sc or iv on days 1-7 of each 28-day cycle) versus va (venetoclax and azacitidine 75 mg/m2 sc or iv on days 1-7 of each 28-day cycle). part b notes cusatuzumab 10 mg/kg iv on day 3 and 17 for cycles 1 and 2 then 20 mg/kg iv on day 3 and day 17 for cycle 3 and beyond, with venetoclax and azacitidine as above.-controlled, adaptive Phase II trial in Germany, Spain.

Comparator
Two arms: VAC (cusatuzumab 20 mg/kg IV on Day 3 and Day 17 of the 28-day cycle in combination with venetoclax and azacitidine 75 mg/m2 SC or IV on Days 1-7 of each 28-day cycle) versus VA (venetoclax and azacitidine 75 mg/m2 SC or IV on Days 1-7 of each 28-day cycle). Part B notes cusatuzumab 10 mg/kg IV on Day 3 and 17 for cycles 1 and 2 then 20 mg/kg IV on Day 3 and Day 17 for cycle 3 and beyond, with venetoclax and azacitidine as above.
Adaptive
True, dose-escalation element for cusatuzumab (Part B: initial 10 mg/kg IV on Day 3 and 17 for cycles 1-2, escalating to 20 mg/kg IV on Day 3 and 17 from cycle 3 onward).
