Efficacy, Safety and Immunological Evaluation of Upadacitinib for Relapsing Polychondritis

Relapsing polychondritis (RP) is a rare, systemic autoimmune disorder characterized by episodic inflammation of cartilaginous structures. The goal of this clinical trial is to learn if drug Upadacitinib works to treat relapsing polychondritis in adults. It will also learn about the safety of drug Upadacitinib. The main questions it aims to answer are: * Does drug Upadacitinib reduce the disease activity of relapsing polychondritis? * What medical problems do participants have when taking drug Upadacitinib? Researchers will compare drug Upadacitinib to conventional therapies (treatment with corticosteroids combined with immunosuppressants) to see if drug Upadacitinib works to treat relapsing polychondritis. Participants will: * Take drug Upadacitinib or corticosteroids combined with immunosuppressants every day for 24 weeks. * Visit the hospital once every month for checkups and tests. This clinical study will explore the efficacy and immunological evaluation of Upadacitinib in the treatment of RP.
