简要总结
This study is a prospective, open-labelled, randomized, controlled, single-center clinical trial. The aim of this study is to investigate the remission rate of patients treated with Telitacicept combined with Rituximab in remission-induction and Telitacicept alone in remission-maintain treatment.
详细描述
Background: The basic theme of AAV is relapse and remission. The maintenance therapy of AAV aimed to reduce or prevent relapse is very challenge. Although many medications have been used for the maintenance of AAV, Telitacicept (a BAFF/APRIL dual-target-inhibitor, which has been proved to be effect in treatment of SLE) has not been studied yet. One study tested the efficacy of Belimumab in the maintenance therapy for AAV. When taken Rituximab as remission-induction treatment, no relapse was observed. However, the sample size of this study is small, and the Belimumab, as a BAFF inhibitor, was not been proved to have effect on APRIL.
Many experiences have been accumulated about the efficacy and safety of Telitacicept in Chinese patients with rheumatic diseases. But there is no study to show its effectiveness in the reduction of the relapse of AAV in China. In this study, we take Telitacicept as maintain treatment in AAV patients who receive Rituximab as remission-induction treatment, to verify the effectiveness of Telitacicept in maintenance therapy of AAV.
Objectives: To investigate the effectiveness of Telitacicept in reducing relapse rate by using from remission-induction treatment combined with Rituximab to maintenance treatment of AAV.
Study Design: This is a prospective, randomized, open-label, control, pilot study.

研究组 & 干预措施
Placebo arm
Patients with active AAV will be treated with Rituximab and glucocorticoid to induce remission. And the placebo of Telitacicept would be given 80 mg every week subcutaneously for 12 months. Glucocorticoid would be tapered as recommended by 2022 EULAR AAV recommendation (as protocol of PEXIVAS study)
干预措施: Placebo of Telitacicept (Other)
Telitacicept treatment arm
Patients with active AAV will be treated with Rituximab and glucocorticoid to induce remission. And the Telitacicept would be given 80 mg every week subcutaneously for 12 months. Glucocorticoid would be tapered as recommended by 2022 EULAR AAV recommendation (as protocol of PEXIVAS study)
干预措施: Telitacicept (Drug)
