Can a second drug stop the body from rejecting arthritis treatment?
NCT ID NCT01895764
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding methotrexate to adalimumab (a biologic drug) reduces the chance that the body makes antibodies against adalimumab in people with ankylosing spondylitis. About 110 adults with active disease who did not respond well to NSAIDs took part. The goal was to see if the combination helps the biologic stay effective longer.
