Anti-CD20 Antibodies for Treatment of SLE-PAH

Summary

This is a prospective, single-arm, single-center, explorative clinical trial to evaluate the effect of Rituximab on disease progression in subjects with SLE-PAH receiving concurrent stable-dose standard medical therapy. The study will focus on assessment of clinical response and safety measures longitudinally. In addition, the biomarker of treatment efficacy with Rituximab and pathogenic autoantibody response in this disease will be investigated.
