|
E.4 | Principal exclusion criteria |

•History of HIV or any other immunodeficiency disease.

E.5 End points |
E.5.1 | Primary end point(s) |
•A subject is defined as a responder for the composite renal response endpoint if they meet the following criteria at the 9 months 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) an increase in C3 to ≥80% (i.e., ≥72 mg/dL or 0.72 g/L) of the lower limit of normal (LLN, 90 mg/dL or 0.9 g/L). Initiation of treatment with eculizumab or any other complement pathway modifying agent automatically designates the subject as a non-responder.
•Occurrence of clinically significant vital signs (msDBP, msSBP, heart rate), ECGs, and safety laboratory measurements, as well as adverse events (AEs), AEs of special interest, and study drug discontinuation due to an AE (or any safety issue). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
•9-months visit
•9-months visit, end of study |
|
E.5.2 | Secondary end point(s) |
•Change from baseline in log-transformed urine protein/creatinine ratio (UPCR), change from baseline in log-transformed urine albumin/creatinine ratio (UACR), change from baseline in serum creatinine concentration and change from baseline in estimated glomerular filtration rate (eGFR) at the 9 months visit in CLNP023B12001B.
•C3 deposit score, disease activity and chronicity scores from a renal biopsy at 6 to 9 months from entry to the CLNP023B12001B study. Biopsies will be compared to those obtained in the CLNP023X2202 study (if available).
•Change from baseline in circulating levels of complement components C3 (serum), change from baseline in Bb (plasma) and change from baseline in sC5b-9 (plasma) at the 9 months visit in CLNP023B12001B.
•Change from baseline in urinary kidney biomarkers such as neutrophil gelatinase-associated lipocalin (NGAL) at the 9 months visit in CLNP023B12001B compared to the baseline visit in CLNP023X2202.
•A subject is defined as a responder for the composite renal response endpoint if they meet the following criteria at times >9 months and up to 36 months 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) an increase in C3 to ≥80% (i.e., ≥72mg/dL or 0.72 g/L) of the lower limit of normal (LLN, 90 mg/dL or 0.9 g/L). Initiation of treatment with eculizumab or any other complement pathway modifying agent automatically designates the subject as a non-responder.
•Change from baseline in log-transformed UPCR, log-transformed UACR, serum creatinine concentration and estimated glomerular filtration rate (eGFR) at times >9 months and up to 36 months in CLNP023B12001B.
•Change in C3 deposit score, disease activity and chronicity scores from a renal biopsy at times >9 months and up to 36 months from entry to the CLNP023B12001B study.
•Change from baseline in circulating levels of complement pathway components C3, Bb and sC5b-9 at times >9 months and up to 36 months in CLNP023B12001B.
•Determine plasma LNP023 concentration up to 12 months at trough
