Novel JAK1 Inhibitor Hits the Mark in Rheumatoid Arthritis Trial

Ivarmacitinib, a novel Janus kinase 1 inhibitor, alleviates symptoms, reduces disease activity, and improves physical function and quality of life in patients with moderate to severe rheumatoid arthritis (RA) who have an inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs).

This phase 3 trial, conducted across 59 sites in China, evaluated the efficacy and safety of ivarmacitinib in patients with moderate to severe active RA despite treatment with one or more csDMARDs.

This study was led by Jinjing Liu and Xiaofeng Zeng, Department of Rheumatology and Clinical Immunology, Peking Union Medical College Hospital, Beijing, China. It was published online on November 27, 2024.
