Clinical Characteristics and Mechanism Research of Deucravacitinib in the Idiopathic Inflammatory Myopathies

April 26, 2026 updated by: He Jing, Peking University People's Hospital

Real-world Experience With Deucravacitinib for the Treatment of Idiopathic Inflammatory Myopathies -- a Prospective Observational Study

This study aims to explore the clinical characteristics and mechanism of Deucravacitinib in the treatment of idiopathic inflammatory myopathies.Detailed Description: The investigators designed a single center, open-label, prospective study. Adults with active idiopathic inflammatory myopathies will be enrolled, meeting the Bohan & Peter Dermatomyositis/Polymyositis(DM/PM) or Rheumatology(ACR) & European allance of associations for rheumatology(EULAR)(2017) diagnostic criteria. Deucravacitinib 6 mg once a day was administered for 6 months to explore its efficacy and safety, which could help to evaluate Deucravacitinib clinical characteristics and mechanism. Patients would be evaluated the improvement of clinical and laboratory indexes. Changes of symptoms, immune cell subsets and cytokines were monitored. Symptoms were evaluated by Visual Analogue Scale (VAS) of patient global and physician global, manual muscle testing(MMT-8), the Health Assessment Questionnaire(HAQ), Creatine kinase, Myositis Disease Activity Assessment Tool(MDAAT).
