Proportion of participants achieving a sustained increase in hemoglobin levels of ≥ 2 g/dL in the absence of red blood cell transfusion |
|
E.2.2 | Secondary objectives of the trial |
- Proportion of participants achieving sustained hemoglobin levels ≥ 12 g/dL in the absence of red blood cell transfusions - Transfusion avoidance (TA) defined as the proportion of participants who remain free from transfusions - Change from baseline in hemoglobin - Percent change from baseline in LDH - Rate of breakthrough hemolysis (BTH) - Change from baseline in reticulocyte counts - Change in fatigue score, using the FACIT-Fatigue questionnaire - Rates of Major Adverse Vascular Events (MAVEs incl. thrombosis) |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Male and female participants ≥ 18 years of age with a diagnosis of PNH confirmed by high-sensitivity flow cytometry with RBCs and WBCs clone size ≥ 10% - Mean hemoglobin level <10 g/dL • LDH > 1.5 x Upper Limit of Normal (ULN) - Vaccination against Neisseria meningitidis infection is required, and is recommended at least 2 weeks prior to initiation of iptacopan treatment.However, administration of these vaccines less than 2 weeks prior to start of iptacopan treatment or up to 2 weeks (up to Day 14) after iptacopan initiation, is at the discretion of the investigator. If iptacopan treatment is started less than 2 weeks post-vaccination or before a specific vaccination is given, participant must be given prophylactic antibiotic at the start of iptacopan and for at least 2 weeks after vaccination. -If not received previously, vaccination against Streptococcus pneumoniae and Haemophilus influenzae should be given (if available and according to local/national regulations), and are recommended at least 2 weeks prior to initiation of iptacopan treatment. However, administration of these vaccines less than 2 weeks prior to start of iptacopan treatment or up to 2 weeks (up to Day 14) after iptacopan initiation, is at the discretion of the investigator. If iptacopan treatment is started less than 2 weeks post-vaccination or before a specific vaccination is given, participant must be given prophylactic antibiotic at the start of iptacopan and for at least 2 weeks after vaccination.
Other protocol defined inclusion/exclusion criteria may apply. |

E.4 | Principal exclusion criteria |
- Prior treatment with a complement inhibitor, including anti-C5 antibody - Known or suspected hereditary complement deficiency - History of hematopoietic stem cell transplantation - Patients with laboratory evidence of bone marrow failure (reticulocytes <100x109/L; platelets <30x109/L; neutrophils <0.5x109/L). - Active systemic bacterial, viral (incl. COVID-19)or fungal infection within 14 days prior to study drug administration - History of recurrent invasive infections caused by encapsulated organisms, e.g. meningococcus or pneumococcus. - Major concurrent comorbidities including but not limited to severe kidney disease (e.g., dialysis), advanced cardiac disease (e.g., NYHA class IV heart failure), severe pulmonary disease (e.g., severe pulmonary hypertension (WHO class IV)), or hepatic disease (e.g., active hepatitis) that in the opinion of the investigator precludes participant's participation in the study.
Other protocol defined inclusion/exclusion criteria may apply. |
