Brief Summary

This study is a randomized, double-blind, placebo-controlled Phase II clinical trial to evaluate the efficacy and safety of SHR-2173 in patients with Primary IgA Nephropathy(IgAN). The study consists of a screening period, a run-in period, a 48-week double-blind treatment period, and a 12-week follow-up period. Approximately 84 IgAN patients will be included.

Receivied immunosuppressive therapy within 12 weeks before randomization; 3. Received any investigational drug within 4 weeks before randomization or within the 5 half-lives of the trial drug, whichever was longer; 4. Received a live / attenuated live vaccine administered within 4 weeks before randomization 3、History and examination related to infection: 1. A history of infection (viral, bacterial, fungal, parasitic infection) within 3 months prior to screening, resulting in hospitalization and/or parenteral systemic antimicrobial therapy; Or a history of infection requiring systemic antimicrobial therapy within 14 days before randomization; 2. Tuberculosis (TB) or occult TB infection (one of the following conditions) : 1. Presence of active TB or clinical symptoms of active TB at screening; 2. Signs of active TB on imaging examination within 3 months before screening 4、 General situation: 1\) Pregnant or lactating women; 2) Investigators determine that there are circumstances that affect the safety and efficacy evaluation of the investigational drug, or other circumstances not appropriate for participation in this study.
