Primary | Percentage of participants with complete TMA response without the use of PE/PI and anti-C5 antibody | The number/percentage of participants treated with iptacopan achieving complete thrombotic microangiopathy (TMA) response during 26 weeks of study treatment.
Complete TMA Response is defined as (1) hematological normalization in platelet count (platelet count =150 x 10^9/L) and LDH (below ULN), and (2) improvement in kidney function (= 25% serum creatinine reduction from baseline), maintained for two measurements obtained at least four weeks apart, and any measurement in between |
26 weeks of study treatment | |
Primary | Long term safety and efficacy evaluations | Long term (one year) safety, tolerability and efficacy of iptacopan via 1) safety evaluations including adverse events/serious adverse events, safety laboratory parameters, vital signs etc. after 52 weeks of study treatment, and 2) efficacy evaluations including complete TMA response, hematological parameters (platelets, LDH, hemoglobin), eGFR, PROs after 52 weeks of study treatment | 52 weeks of study treatment | |
Secondary | Time to achieve complete TMA response | Effect of study treatment iptacopan on time to complete TMA response during the first 26 weeks of study treatment | 26 weeks of study treatment | |
Secondary | Percentage of participants with increase from baseline in hemoglobin levels = 2 g/dL | Response is defined as the percentage of participants with an increase in hemoglobin of = 2 g/dL from baseline, observed at two measurements obtained at least 4 weeks apart and any measurement in between during 26 weeks of study treatment | 26 weeks of study treatment | |
Secondary | Change from baseline on hematologic parameters | Change from baseline in hematologic parameters (platelets, LDH, hemoglobin) at Week 26 | At week 26 | |
Secondary | Percentage of participants on dialysis | For participants requiring dialysis within 5 days prior to iptacopan treatment initiation, the number of participants who no longer require dialysis through 26 weeks of study treatment will be evaluated by means of proportion and corresponding confidence interval | 26 weeks of study treatment | |
Secondary | Change from baseline on estimated glomerular filtration rate | Change from baseline in eGFR after 26 weeks of study treatment. | At week 26 | |
Secondary | Change from baseline in chronic kidney disease (CKD) stage | Change from baseline in CKD stage (1-5) based on eGFR categories at Week 26 | At week 26 | |
Secondary | Change from baseline in patient-reported outcomes score as measured by the Functional Assessment Of Chronic Illness Therapy (FACIT)-Fatigue Questionnaire | Change from baseline in patient-reported outcomes scores for FACIT-Fatigue Questionnaire at Week 26 | At week 26 | |
Secondary | Change from baseline in patient-reported outcomes score as measured by the EuroQol 5-level EQ-5D version (EQ-5D-5L) Questionnaire | Change from baseline in patient-reported outcomes scores for the EuroQol 5-level EQ-5D version (EQ-5D-5L) Questionnaire at Week 26 | At Week 26 | |
Secondary | Change from baseline in patient-reported outcomes score as measured by the Patient Global Impression of Severity (PGIS) questionnaire | Change from baseline in patient-reported outcomes scores for Patient Global Impression of Severity (PGIS) at Week 26 | At Week 26 | |
Secondary | Change from baseline in patient-reported outcomes score as measured by the Short-form 36 health survey questionnaire version 2 (SF-36 v2) | Change from baseline in patient-reported outcomes scores for Short-form 36 health survey questionnaire version 2 (SF-36 v2) at Week 26 | At Week 26 |
