| Primary | 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 | 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 | Marginal Proportion (Expressed as Percentage) With Sustained Hemoglobin Levels of ≥ 12 g/dL in the Absence of Red Blood Cell Transfusions | 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. |
| Secondary | Marginal Proportion (Expressed as Percentage) of Participants Who Remain Free From Transfusions | 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 |
| Secondary | Change From Baseline in Hemoglobin Levels in the Core Treatment Period | 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. |
| Secondary | Percent Change From Baseline in LDH | 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. |
| Secondary | Adjusted Annualized Clinical BTH Rate in the Core Treatment Period | 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. |
| Secondary | Change From Baseline in Absolute Reticulocyte Count | 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. |
| Secondary | Change From Baseline in FACIT-Fatigue Score | 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. |
| Secondary | Adjusted Annualized Major Adverse Vascular Events Rate in the Core Treatment Period | 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. |
| Other | Percentage of Patients Meeting Hematological Response Criteria Irrespective of RBC Transfusions | Baseline, Day 336 | Patients with hematological response are those with an increase in Hb from baseline ≥ 2g/dL irrespective of red blood cell (RBC) transfusions and patients achieving Hb ≥ 12g/dL irrespective of RBC transfusions. |
| Other | Marginal Proportion (Expressed as Percentage) of Patients Not Receiving and Not Requiring RBC Transfusions | Between Day 14 and Day 336 | Requiring Red Blood Cells (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). |
| Other | Change From Baseline in Hemoglobin Levels | Baseline, Day 336 | Change from baseline in Hemoglobin at Visit Day 336 |
| Other | Change From Baseline in LDH at Visit Day 336 | Baseline, Day 336 | Change from baseline in Lactate dehydrogenase (LDH) at Visit Day 336 |
| Other | Adjusted Annualized Clinical BTH Rate After the Start of LNP023 Treatment | Between Day 1 and Day 336 | 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. |
| Other | Change From Baseline in Absolute Reticulocyte Count at Day 336 | Baseline, Day 336 | Change from baseline in absolute reticulocyte count at visit Day 336. |
