Outcome Measures
Primary Outcome Measures
- RBC transfusion independence for ≥ 28 days immediately prior to any scheduled clinical visit up to Week 24 [24 weeks]
Transfusion independence is defined as no RBC or platelet transfusion attributable to, or required to manage, thrombotic microangiopathy (TMA). Transfusions required for causes other than TMA will not be considered within the evaluation of the primary efficacy endpoints.
- Urine protein creatinine ratio ≤ 2 mg/mg [24 weeks]
Urine protein creatinine ratio ≤ 2 mg/mg
Secondary Outcome Measures
- Renal Function Improvement [24 weeks]
Percentage of patients who achieve the primary endpoint of urine protein creatinine ratio ≤ 2 mg/mg (the nephrotic threshold) for ≥ 28 days
- Platelet transfusion independence [24 weeks]
Platelet transfusion independence for ≥ 28 days within the 24 week timeframe
- Normalisation of lab parameters [24 weeks]
Serum sC5b-9 ≤ ULN
- Normalisation of lab parameters [24 weeks]
Lactate dehydrogenase (LDH) ≤ULN
- Normalisation of lab parameters [24 weeks]
Normalization of haptoglobin
- Safety and tolerability of nomacopan [28 weeks]
New or worsening AEs after dosing of investigational product will be recorded in the eCRF.
- Safety and tolerability of nomacopan [28 weeks]
Listings of subjects who have an SAE.
- Safety and tolerability of nomacopan [28 weeks]
Listings of subjects who discontinue from the study due to an AE.
- Safety and tolerability of nomacopan [28 weeks]
Occurrence of significant laboratory abnormalities will be summarized.
