Rheumatoid arthritis drug study halted early – what we know
NCT ID NCT06031415
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested an experimental drug called GS-0272 in adults with rheumatoid arthritis to see if it is safe and how the body processes it. The trial was stopped early, so results are limited. About 55 people were planned to take part, receiving either the drug or a placebo.

Part B (Active RA Cohort)-Specific Inclusion Criteria: * Participant is seropositive as demonstrated by a positive anti-cyclic citrullinated peptide (anti-CCP) antibody and/or positive rheumatoid factor at screening. * Participant has an elevated high-sensitivity C-reactive protein (hsCRP) greater than upper limit of normal (ULN). * Participant has 6 or more swollen and 6 or more tender joints as assessed on the SJC66/TJC68. Distal interphalangeal joints will not be counted towards the 6 joint eligibility. * Participant has had inadequate response or intolerance to at least 1 but not more than 3 bDMARD/tsDMARD therapeutics with no more than 2 MOAs. A lack of response is defined as documented continued or recurrent disease activity after at least 12 weeks of treatment of RA.
