NCT07168161
The primary aim is to study the efficacy of treatment with BDB-001 Injection to induce remission in patients with active anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), when used in combination with cyclophosphamide followed by azathioprine, or in combination with rituximab

Autoimmune diseases refer to a common category of diseases caused by the immune system reacting to self-antigens, leading to tissue damage. Autoimmune diseases encompass a wide variety of conditions, such as systemic lupus erythematosus（SLE）, Sjögren's syndrome (SS), systemic sclerosis (SSc), inflammatory myopathies (IM), ANCA-associated vasculitis (AAV), and antiphospholipid syndrome (APS). They affect the quality of life, while in severe cases, they can be life-threatening. Additionally, they impose a heavy economic burden on society. Current treatments for autoimmune diseases include glucocorticoid, immunosuppressants, and biologics. B cell-driven humoral immune abnormalities are a central pathogenic mechanism in many autoimmune diseases. When autoreactive B cells are excessively activated, they produce large amounts of autoantibodies and immune complexes. These antibodies and immune complexes can cause damage to various tissues and organs, leading to the development of multiple autoimmune diseases. Therefore, targeting B cells to treat autoimmune diseases is an attractive therapeutic strategy. Chimeric Antigen Receptor (CAR)-T cells targeting the B cell surface molecule CD19 have achieved significant clinical progress in acute lymphoblastic leukemia and B cell non-Hodgkin lymphoma, with several CD19 CAR-T therapies approved for marketing worldwide. Increasingly, clinical studies are exploring the use of CD19 CAR-T cells for the treatment of autoimmune diseases, and their therapeutic efficacy has been demonstrated. In this study, the investigators used γδ T cells as carrier cells to investigate the safety and efficacy of universal CAR-γδ T cells in the treatment of autoimmune diseases.
NCT06611696
The goal of this clinical trial is to learn if avacopan in combination with short-term (4 weeks) reduced-dose glucocorticoid and rituximab works to treat patients with newly-onset ANCA-associated vasculitis. It will also learn about the long-term safety of avacopan. The main questions it aims to answer are: Is avacopan in combination with short-term reduced-dose glucocorticoid and rituximab as effective as the combination of 20 week reduced-dose glucocorticoid and rituximab in the proportion of the patients achieving remission? Does avacopan lower the relapse rate compared to the 6 monthly rituximab maintenance therapy? What medical problems do participants have when taking long-term avacopan? Participants will: Be treated with avacopan in combination with short-term (until 4 weeks) reduced-dose glucocorticoid and rituximab (at 0 week) or reduced-dose glucocorticoid (until 20 weeks) and rituximab (at 0, 26, 52 and 78 weeks). Be assessed at 0, 4, 8, 16, 26, 52, 78 and 104 weeks regarding disease status (remission/relapse), disease activity by Birmingham Vasculitis Activity Score ver3, disease damage by Vasculitis Damage Index and adverse events. The primary endpoint is remission rates at 26 weeks.

NCT06642870
The rare autoimmune rheumatic diseases (RAIRDs) are life-long multi-system diseases that are life or organ threatening. RAIRDs can impair quality of life similar to chronic diseases such as heart failure. The aim of the study is to explore content and structure of a support programme for people with RAIRDs in focus groups and survey meetings.
