简要总结
This is an open-label extension study to evaluate the long-term efficacy, safety and tolerability of iptacopan in subjects with C3 glomerulopathy or idiopathic immune-complex-membranoproliferative glomerulonephritis
详细描述
The primary purpose of this extension study is to collect long-term efficacy, safety and tolerability data in eligible participants receiving open-label iptacopan after completing treatment in the C3G Phase 2 proof of concept study CLNP023X2202.
The primary (at 9 months) and longer-term (>9 months) efficacy and safety data of iptacopan collected from CLNP023X2202 participants will be used to support health authority submissions.
This umbrella protocol will also allow:
- continued access to iptacopan to patients enrolled in the ongoing Phase 3 programs (C3G and IC-MPGN)
- C3G study (CLNP023B12301): adults and adolescents
- IC-MPGN study (CLNP023B12302): adults and adolescents
- provision of additional efficacy and safety information following longer-term treatment in C3G and IC-MPGN populations to support health authority submissions.
Efficacy and safety assessments at the 9 month visit of this extension study in combination with data from CLNP023X2202 (baseline plus 3 months of treatment) allowed evaluation of the effects of iptacopan on potential endpoint(s) at 12 months of iptacopan treatment in C3G participants. The enrollment of C3G and IC-MPGN participants (adults and adolescents) from Phase 3 studies, CLNP023B12301 and CLNP023B12302, permits longer-term evaluation of the persistence of effects observed after iptacopan treatment. These longer term efficacy and safety assessments may be compared to historical/concurrent control data available from relevant real world databases in C3G or IC-MPGN patients and used as supportive information for registration purposes.

结局指标
主要结局
CLNP023X2202 Cohort A-native C3G: Number of participants who achieve the composite renal endpoint
时间窗: 9-month visit
A participant meets the requirements of the composite renal endpoint if they satisfy the following criteria at the 9-month visit in CLNP023B12001B: (1) a stable or improved eGFR compared to the baseline visit in CLNP023X2202 (≤10% reduction in eGFR), and (2) either ≥50% reduction compared to the baseline visit in CLNP023X2202 or a reduction to \<300 mg/g in UPCR and (3) either a ≥50% increase in C3 compared to baseline or an increase to ≥90 mg/dL (i.e., ≥ the lower limit of normal (LLN)). Initiation of treatment with eculizumab or any other complement pathway modifying agent automatically designates the participant as not meeting the endpoint.
