Official title
A Prospective, Open-label, Controlled, Single Center Clinical Study of the Efficacy and Safety for Telitacicept in the Remission Maintenance Treatment of ANCA-associated Vasculitis
Overview
This study is a prospective, open-labelled, randomized, controlled, single-center clinical trial. The aim of this study is to compare the remission rate of patients treated with Telitacicept combined with azathioprine and azathioprine alone in remission-maintenance treatment of AAV.
Detailed description
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 add Telitacicept to azathioprine in maintain treatment in AAV patients who receive Rituximab as remission-induction treatment, to compare the relapse rates of Telitacicept combining azathioprine and azathioprine alone in maintenance therapy of AAV.
Objectives: To compare the relapse rates of Telitacicept combining azathioprine and azathioprine alone in maintenance treatment of AAV.
Study Design: This is a prospective, randomized, open-label, control, pilot study.
Interventions
- Drug Azathioprine
All patients included into this study will be treated with Azathioprine tablets 100mg QD for 12 months. - Drug Telitacicept
Patient will be treated with Telitacicept (Taiai the commercial name) 160 mg every week subcutaneously for 12 months
Primary outcome measures
- The time of first relapse during 12 months follow-up of two groups [Time frame: from inclusion to the end of the study, 12 months in total]
Secondary outcome measures (7)
- The percentage of patients with severe relapse at months 12 [Time frame: from inclusion to the end of the study, 12 months in total]
- The percentage of patients with moderate relapse at months 12 [Time frame: from inclusion to the end of the study, 12 months in total]
- The percentage of patients with mild relapse at months 12 [Time frame: from inclusion to the end of the study, 12 months in total]
- The percentage of patients with sustained remission at months 12 [Time frame: from inclusion to the end of the study, 12 months in total]
- The rate of adverse events [Time frame: from inclusion to the end of the study, 12 months in total]
- The percentage of patients who progress to ESRD [Time frame: from inclusion to the end of the study, 12 months in total]
- The rate of complication of AAV [Time frame: from inclusion to the end of the study, 12 months in total]
