NCT07522099

Brief Summary

This is a Phase 2 study to assess the safety, efficacy, pharmacokinetics (PK) and pharmacodynamics of ADX-038 in adults with complement-mediated kidney diseases. The study will enroll Chinese adults with IgA nephropathy, complement 3 glomerulopathy (C3G) and immune complex membranoproliferative glomerulonephritis (IC-MPGN). The study will evaluate ADX-038 administered alone (Part A) and in combination with telitacicept (Part B).
