Focal Segmental Glomerulosclerosis (FSGS), IgA Nephropathy (IgAN), Minimal Change Disease (MCD)
Conditions
Brief summary
This is a Phase 1b/2, open-label, multi-center study evaluating the therapeutic potential and safety of the investigational drug EVER001 in adults with FSGS, MCD, or IgAN. EVER001 acts on multiple immune pathways without directly affecting T cells or depleting B cells (both are lymphocytes). The study will be conducted at \ 30 centers in China, enrolling 45 participants aged 18-75 years (15 per indication). The IMP is a 100 mg oral capsule, dosed at 200 mg twice daily (2 capsules per dose, 4 daily) for 52 weeks.
Interventions
EVER001 200 mg, oral administration, twice daily (bid), for the treatment of proteinuric glomerular diseases including FSGS , MCD , and IgA
