简要总结
The purpose of the study was to find out if iptacopan is effective and safe in adult patients with Paroxysmal Nocturnal Hemoglobinuria (PNH) who switched from their current standard of care treatment (eculizumab or ravulizumab) to study treatment, iptacopan/LNP023.
详细描述
This was a multicenter, single-arm, open label trial, with iptacopan treatment for 24 weeks in adult PNH patients. This study was comprised of two periods: * A Screening period lasting up to 8 weeks. * A 24-week open-label, iptacopan Treatment period. After completion of the treatment period, participants who continued to benefit from the iptacopan treatment based on the study doctor's evaluation were able to join the Roll-over extension study (CLNP023C12001B).

结局指标
主要结局
Change in Hb Levels as Mean of Visits Between Day 126 and Day 168 Compared to Baseline Tested for Non-inferiority
时间窗: Baseline, Day 126 to Day 168
Change in hemoglobin (Hb) levels as mean of visits between Day 126 and Day 168 compared to baseline. Baseline is defined as as the mean of three Hb assessments conducted at the central laboratory: two during screening and the third on Day 1. The estimation of change from baseline in Hb levels was handled by the hypothetical strategy where participants were assumed as if they did not receive RBC transfusions while on treatment (RBC transfusions were expected to be rare). Assuming that participants had stable Hb levels at study entry, the mean change from baseline in Hb level between Day 126 and Day 168 was expected to be unchanged should participants have continued on anti-C5 treatment. Non-inferiority of iptacopan was therefore tested by the null hypothesis (H0) against the alternate hypothesis (H1) comparing the mean change from baseline in Hb level in iptacopan between Day 126 and Day 168 (μ) to -1 g/dL: H0: μ \<= -1, H1: μ \> -1.
