Brief Summary:
The overall aim of the study is to evaluate the efficacy, safety, and tolerability of Nefecon 16 mg per day in the treatment of patients with primary IgAN (Immunoglobulin A nephropathy) at risk of progressing to end-stage renal disease (ESRD), despite maximum tolerated treatment with renin-angiotensin system (RAS) blockade using angiotensin converting enzyme inhibitors (ACEIs) or angiotensin II type I receptor blockers (ARBs).

Condition or disease Intervention/treatment Phase
Primary IgA Nephropathy Drug: Nefecon Drug: Placebo oral capsule Phase 3

Detailed Description:
This is a Phase 3, randomized, double-blind, placebo-controlled, multicenter study to evaluate the efficacy, safety, and tolerability of oral Nefecon compared to matching placebo in patients with primary IgAN on a background of optimized RAS inhibitor therapy. The study will consist of 2 parts, Part A and Part B. Part A will include a 9 month blinded Treatment Period, and a 3-month Follow up Period. Part B will consist of an observational Long-term Follow up Period in which the patients will be followed until 100 clinical events, measured as reduction in eGFR compared to baseline. Part A and B will be blinded. Safety will be monitored by an independent Data Safety Monitoring Board.

Primary Outcome Measures :
  1. Change in Proteinuria, measured as Urine Protein to creatinine ratio (UPCR). [ Time Frame: 9 months ]
    The primary outcome measure is UPCR (based on 24-hour urine collections) at 9 months following the first dose of study drug compared to baseline

  2. Events based on renal function measured as estimated glomerular filtration rate (eGFR) [ Time Frame: Up to 6 years ]
    Events based on eGFR measure compared to baseline calculated using the CKD-EPI formula


Secondary Outcome Measures :
  1. The incidence of treatment-emergent adverse events. [ Time Frame: From enrollment and up to 6 years ]
  2. Renal function [ Time Frame: Up to 6 years ]
    Renal function measured as eGFR using the CKD-EPI formula
