ListOutcomeTime frameDescription
PrimaryPercent Change In Lactate Dehydrogenase Levels From Baseline To Day 183Baseline, Day 183
Lactate dehydrogenase (LDH) is an indicator of intravascular hemolysis that occurs in participants with paroxysmal nocturnal hemoglobinuria. A decrease in LDH indicates reduction (improvement) in hemolysis. Baseline was defined as the average of all available on-study assessments prior to the first study drug infusion. The percent change in LDH was analyzed using a mixed-effect model for repeated measures (MMRM) with the fixed, categorical effects of treatment, study visit, and study visit by treatment group interaction, as well as the continuous, fixed covariate of baseline LDH and the stratification randomization indicator of packed red blood cells transfusion history (yes/no within 12 months prior to Day 1).
SecondaryNumber Of Participants With Breakthrough Hemolysis Through Day 183Baseline through Day 183
Breakthrough hemolysis (BTH) was defined as at least one new or worsening symptom or sign of intravascular hemolysis (fatigue, hemoglobinuria, abdominal pain, dyspnea, anemia \[hemoglobin \<10 grams (g)/deciliter (dL)\], major adverse vascular event \[including thrombosis\], dysphagia, or erectile dysfunction) in the presence of elevated LDH ≥2 times the upper limit of normal (ULN).
SecondaryChange From Baseline To Day 183 In Functional Assessment Of Chronic Illness Therapy (FACIT)-Fatigue ScoresBaseline, Day 183
FACIT-Fatigue score ranges from 0 to 52, with a higher score indicating less fatigue. Baseline was defined as the last non-missing assessment value prior to first study drug dose. Change in FACIT-Fatigue score from Baseline to Day 183 was analyzed using an MMRM with the fixed, categorical effects of treatment, the stratification randomization indicator of packed red blood cells transfusion history (yes/no within 12 months prior to Day 1), study visit, and study visit by treatment group interaction, as well as the continuous fixed covariate of Baseline FACIT-Fatigue score.
SecondaryPercentage Of Participants Who Achieved Transfusion Avoidance Through Day 183Baseline through Day 183
Transfusion avoidance was defined as the percentage of participants who remained transfusion free and did not require a transfusion per protocol-specified guidelines (hemoglobin value of ≤9 g/dL with signs or symptoms of sufficient severity to warrant a transfusion, or a hemoglobin value of ≤7 g/dL regardless of presence of clinical signs or symptoms) through Day 183.
SecondaryPercentage Of Participants With Stabilized Hemoglobin Levels Through Day 183Baseline through Day 183Stabilized hemoglobin was defined as avoidance of a ≥2 g/dL decrease in hemoglobin level from Baseline in the absence of transfusion through Day 183.
SecondaryNumber Of Participants With Breakthrough Hemolysis Through End of StudyBaseline through end of study (up to 4 years)
BTH was defined as at least one new or worsening symptom or sign of intravascular hemolysis (fatigue, hemoglobinuria, abdominal pain, dyspnea, anemia \[hemoglobin \<10 g/dL\], major adverse vascular event \[including thrombosis\], dysphagia, or erectile dysfunction) in the presence of elevated LDH ≥2 times the ULN.
SecondaryChange From Baseline To End of Study In FACIT-Fatigue Scores Through End of StudyBaseline, End of Study (up to 4 years)
FACIT-Fatigue score ranges from 0 to 52, with a higher score indicating less fatigue. Baseline was defined as the last non-missing assessment value prior to first study drug dose. Change in FACIT-Fatigue score from Baseline to Day 183 was analyzed using an MMRM with the fixed, categorical effects of treatment, the stratification randomization indicator of packed red blood cells transfusion history (yes/no within 12 months prior to Day 1), study visit, and study visit by treatment group interaction, as well as the continuous fixed covariate of Baseline FACIT-Fatigue score.
SecondaryPercentage Of Participants Who Achieved Transfusion Avoidance Through End of StudyBaseline through end of study (up to 4 years)
Transfusion avoidance was defined as the percentage of participants who remained transfusion free and did not require a transfusion per protocol-specified guidelines (hemoglobin value of ≤9 g/dL with signs or symptoms of sufficient severity to warrant a transfusion, or a hemoglobin value of ≤7 g/dL regardless of presence of clinical signs or symptoms) through the end of study.
SecondaryPercentage Of Participants With Stabilized Hemoglobin Levels Through End of StudyBaseline through end of study (up to 4 years)Stabilized hemoglobin was defined as avoidance of a ≥2 g/dL decrease in hemoglobin level from Baseline in the absence of transfusion through end of study.
