Evaluate the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of EVER001 in Participants With Selected Proteinuric Glomerular Diseases

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.
