Brief Summary:
This is an open-label extension study to evaluate the long-term efficacy, safety and tolerability of LNP023 in subjects with C3 glomerulopathy

Condition or disease Intervention/treatment Phase
C3 Glomerulopathy Drug: LNP023 Phase 2

Detailed Description:
The purpose of this extension study is to collect and evaluate long-term efficacy, safety and tolerability data in eligible participants receiving open label LNP023 after completing the C3G proof of concept (PoC) study CLNP023X2202. Efficacy assessments at the 9 month visit of the extension study in combination with data from CLNP023X2202 (baseline plus 3 months of treatment) will afford the opportunity to evaluate the effects of LNP023 on potential endpoint(s) for the Phase III trial in C3G at 12 months of treatment. Longer-term efficacy assessments may be used as supportive information for registration purposes.

Primary Outcome Measures :
  1. Number of participants with composite renal response [ Time Frame: 9-months visit ]
    A participant is defined as a responder for the composite renal response endpoint if they meet 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 a non-responder.

  2. Number of participants with Adverse Events [ Time Frame: 90 days post LPLT ]
    Evaluate the long-term safety and tolerability of LNP023 in subjects with C3G by occurrence of clinically significant vital signs (msDBP, msSBP, heart rate), ECGs, and safety laboratory parameters, as well as adverse events (AEs), AEs of special interest, and study drug discontinuation due to an AE (or any safety issue).


Secondary Outcome Measures :
  1. Change in urine protein/creatinine ratio (UPCR) [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on renal function in C3G subjects by assessing the change in UPCR at 9 months visit compared to CLNP023X2202 baseline

  2. Change in Urine albumin/creatinine ratio (UACR ) [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on renal function in C3G subjects by assessing the change in UACR at 9 months visit compared to CLNP023X2202 baseline

  3. Change in serum creatinine [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on renal function in C3G subjects by assessing the change in serum creatinine at 9 months visit compared to CLNP023X2202 baseline

  4. Change in estimated glomerular filtration rate(eGFR) [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on renal function in C3G subjects by assessing the change in eGFR at 9 months visit compared to CLNP023X2202 baseline

  5. Status of C3G disease progression [ Time Frame: 6 to 9 months ]
    Describe the status of C3G disease progression based on glomerular histopathology in a renal biopsy at 6 to 9 months from entry to the study compared to those obtained prior to treatment in the CLNP023X2202 study

  6. Levels of complement component C3 [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on specific component of the complement pathway by assessing the change from CLNP023X2202 baseline in circulating levels of complement component C3 at the 9 months visit

  7. Levels of complement component Bb [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on specific component of the complement pathway by assessing the change from CLNP023X2202 baseline in circulating levels of complement component Bb at the 9 months visit

  8. Levels of complement component sC5b-9 [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on specific component of the complement pathway by assessing the change from CLNP023X2202 baseline in circulating levels of complement component sC5b-9 at the 9 months visit

  9. Urine markers of renal damage [ Time Frame: 9-months visit ]
    Long-term effect of LNP023 on urine markers of renal damage by assessing the change from baseline in urinary kidney biomarkers such as neutrophil gelatinase-associated lipocalin (NGAL) at the 9 months visit in study compared to the CLNP023X2202 baseline visit

  10. Longer term effect on the composite renal response endpoint, renal function, renal histopathology and specific components of the complement pathway [ Time Frame: > 9 months ]
    Responder is defined if following criteria at times >9 and < 36 mon are met: (1) a stable or improved eGFR compared to baseline visit (≤10% reduction in eGFR), and (2) either ≥50% reduction compared to baseline visit 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., LLN). Initiation of treatment with eculizumab or any other C-pathway modifying agent automatically designates the participant 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 and < 36 mon. Change in C3 deposit score, disease activity and chronicity scores from a renal biopsy at times >9 and < 36 mon from entry to the study. Change from baseline in circulating levels of C-pathway components C3, Bb and sC5b- 9 at times >9 and < 36 mon.

  11. Pharmacokinetics of LNP023 in subjects under prolonged treatment by determining plasma LNP023 concentration up to 12 months at trough [ Time Frame: 3-months, 6-months, 9-months and 12-months visits ]
    Measurement of LNP023 plasma concentration.

  12. Change from baseline in log-transformed urine protein/creatinine ratio (UPCR) [ Time Frame: 3 months ]
    To assess the effect of LNP023 on UPCR

  13. Change from baseline in log-transformed urine albumin/creatinine [ Time Frame: 3 months visit ]
    To assess the effect of LNP023 on urine albumin/creatinine
