Paroxysmal nocturnal haemoglobinuria (PNH)
Conditions
Brief summary
Cohort A: Percent change in lactate dehydrogenase (LDH), Cohort B: Adequate control of hemolysis (defined as LDH ≤1.5 × ULN) at each visit, Cohort B: Transfusion avoidance (not requiring a red blood cell (RBC) transfusion per the protocol)
