This is a single-arm, open-label, investigator-initiated trial (IIT) designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of RD06-05 in patients with autoantibody-mediated autoimmune diseases. The enrolled population consists of patients with active autoimmune diseases, including systemic lupus erythematosus (SLE), systemic sclerosis (SSc), ANCA-associated vasculitis (AAV), idiopathic inflammatory myopathies (IIM), Sjögren's syndrome (SS), among others.
