Treatment Strategies in IgG4-RD Patients With Re-elevation of Serum IgG4 Level During Maintenance Remission Period

Summary

This study has been designed as a 52-week, randomized double blind placebo controlled multicenter clinical trial. The study aims to compare the efficacy and safety of two treatment strategies in IgG4-RD patients with re-elevation of serum IgG4 level during maintenance remission period: basic maintenance treatment group (continue use of basic maintenance treatment of IgG4-RD) and enhanced treatment group (use low dose mycophenolate mofetil as an add-on therapy of basic maintenance treatment of IgG4-RD).
