New hope for arthritis sufferers: experimental drug GenSci120 enters Mid-Stage trial
NCT ID NCT07423533
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug called GenSci120 in 450 adults with moderate-to-severe rheumatoid arthritis who haven't improved with standard treatments. Participants receive either GenSci120, an existing drug (adalimumab), or a placebo for 14 weeks, followed by an extension period. The main goal is to see if GenSci120 reduces joint pain and swelling better than placebo.
