What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Marginal Proportion (Expressed as Percentage) of Participants With Sustained Increase in Hemoglobin Levels From Baseline of ≥ 2 g/dL in the Absence of Red Blood Cell Transfusions
Time Frame: Baseline, hemoglobin between Day 126 and Day 168 and absence of transfusions between Day 14 and Day 168
|
Sustained increase in hemoglobin levels (responder) is defined as an increase from baseline in hemoglobin levels of ≥ 2 g/dL on three out of four measurements between Day 126 and 168 of the core treatment period, without requiring red blood cell (RBC) transfusions between Day 14 and Day 168. Requiring RBC transfusions refers to any patient receiving transfusions or meeting protocol defined criteria (Hemoglobin level of ≤9 g/dL (≤8 g/dL for Chinese population) with signs and or symptoms of sufficient severity to warrant a transfusion or Hemoglobin of ≤7 g/dL (≤6 g/dL for Chinese population), regardless of presence of clinical signs and/or symptoms). The term 'marginal proportion' can be interpreted as the population average probability of being a responder. Results incorporated a method to handle missing data using multiple imputation. Hence, all 40 patients enrolled contributed to the primary analysis. |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent Change From Baseline in LDH
Time Frame: Baseline, Day 126 to 168
|
Percent change from baseline in lactate dehydrogenase (LDH) levels as mean of visits between Day 126 and Day 168. Percentage change from baseline was analyzed using a mixed model for repeated measures (MMRM) which includes age (indicator variable of age ≥ 45 years), sex, history of transfusion (yes/no) prior to study treatment, visit, baseline LDH as fixed effects and visit*baseline LDH as interaction. Results incorporated a method to handle missing data using multiple imputation. Hence, all 40 patients enrolled contributed to the analysis. |
Baseline, Day 126 to 168
|
Change From Baseline in Absolute Reticulocyte Count
Time Frame: Baseline and mean of visits between Day 126 and 168
|
Change from baseline in absolute reticulocyte counts as mean of visits between Day 126 and Day 168. Change from baseline was analyzed using a MMRM which includes age (indicator variable of age ≥ 45 years), sex, history of transfusion (yes/no) prior to study treatment, visit, baseline reticulocyte counts as fixed effects and visit*baseline reticulocyte counts as interaction. |
Baseline and mean of visits between Day 126 and 168
|
Marginal Proportion (Expressed as Percentage) With Sustained Hemoglobin Levels of ≥ 12 g/dL in the Absence of Red Blood Cell Transfusions
Time Frame: Hemoglobin between Day 126 and Day 168 and absence of transfusions between Day 14 and Day 168
|
Sustained hemoglobin levels (responder) is defined as hemoglobin levels ≥ 12 g/dL on three out of four measurements between Day 126 and 168 of the core treatment period, without requiring red blood cell (RBC) transfusions between Day 14 and Day 168. Requiring RBC transfusions refers to any patient receiving transfusions or meeting protocol defined criteria (Hemoglobin level of ≤9 g/dL (≤8 g/dL for Chinese population) with signs and or symptoms of sufficient severity to warrant a transfusion or Hemoglobin of ≤7 g/dL (≤6 g/dL for Chinese population), regardless of presence of clinical signs and/or symptoms). The term 'marginal proportion' can be interpreted as the population average probability of being a responder. Results incorporated a method to handle missing data using multiple imputation. Hence, all 40 patients enrolled contributed to the analysis. |
Hemoglobin between Day 126 and Day 168 and absence of transfusions between Day 14 and Day 168
|
Marginal Proportion (Expressed as Percentage) of Participants Who Remain Free From Transfusions
Time Frame: Between Day 14 and Day 168
|
Marginal proportion (expressed as percentage) of participants who did not require transfusions between Day 14 and Day 168. Requiring RBC transfusions refers to any patient receiving transfusions or meeting protocol defined criteria (Hemoglobin level of ≤9 g/dL (≤8 g/dL for Chinese population) with signs and or symptoms of sufficient severity to warrant a transfusion or Hemoglobin of ≤7 g/dL (≤6 g/dL for Chinese population), regardless of presence of clinical signs and/or symptoms). The term 'marginal proportion' can be interpreted as the population average probability of being a responder. The 95% CI was obtained using the bootstrap method |
Between Day 14 and Day 168
|
Change From Baseline in Hemoglobin Levels in the Core Treatment Period
Time Frame: Baseline, Day 126 to 168
|
Change from baseline in hemoglobin levels as mean of visits between Day 126 and Day 168. In order to factor out the effect of transfusions in this analysis, if a patient had a transfusion during the core treatment period, the hemoglobin (Hb) values during 30 days following the transfusion were excluded and Hb data were imputed. Change from baseline was analyzed using a mixed model of repeated measures which included age (indicator variable of age ≥ 45 years), sex, history of transfusion (yes/no) prior to study treatment, visit, and baseline hemoglobin as fixed effects and the interaction between visit and baseline hemoglobin levels. |
Baseline, Day 126 to 168
|
Adjusted Annualized Clinical BTH Rate in the Core Treatment Period
Time Frame: Between Day 1 and Day 168
|
Adjusted annualized rate of clinical breakthrough hemolysis (BTH) events is carried out using the Wilson method.
The breakthrough is defined clinical if either there is a decrease in hemoglobin levels equal to or more than 2 g/dL (compared to the latest assessment, or within 15 days) or if patients present signs or symptoms of gross hemoglobinuria, painful crisis, dysphagia or any other significant clinical PNH-related signs & symptoms, in presence of laboratory evidence of intravascular hemolysis.
|
Between Day 1 and Day 168
|
Change From Baseline in FACIT-Fatigue Score
Time Frame: Baseline and mean of visits between Day 126 and Day 168
|
Change from baseline in FACIT-Fatigue scores as mean of visits between Day 126 and Day 168. The FACIT-Fatigue is a 13-item questionnaire with support for its validity and reliability in PNH that assesses patient self-reported fatigue and its impact on daily activities and function. All FACIT scales are scored so that a high score is better. As each of the 13 items of the FACIT-F Scale ranges from 0-4, the range of possible scores is 0-52, with 0 being the worst possible score and 52 the best. Change from baseline was analyzed using a Mixed Model of Repeated Measures (MMRM) which includes age (indicator variable of age ≥ 45 years), sex, history of transfusion (yes/no) prior to study treatment, visit, baseline FACIT-Fatigue score as fixed effects and visit*baseline FACIT-Fatigue score as interaction. |

|
Adjusted Annualized Major Adverse Vascular Events Rate in the Core Treatment Period
Time Frame: Between Day 1 and Day 168
|
Adjusted annual rate is carried out using the Wilson method.
A MAVE is defined as: acute peripheral vascular occlusion, amputation (non-traumatic; nondiabetic), cerebral arterial occlusion/cerebrovascular accident, cerebral venous occlusion, dermal thrombosis, gangrene (non-traumatic; nondiabetic), hepatic/portal vein thrombosis (Budd-Chiari syndrome), mesenteric/visceral arterial, thrombosis or infarction, mesenteric/visceral vein thrombosis or infarction, myocardial infarction, pulmonary embolus, renal arterial thrombosis, renal vein thrombosis, thrombophlebitis / deep vein thrombosis, transient ischemic attack, unstable angina or other.
