Key clinical point: Olokizumab significantly improved signs and symptoms of rheumatoid arthritis (RA) in patients with inadequate response to methotrexate and was reasonably well tolerated over a period of 24 weeks.
Major finding: At 12 weeks, the proportion of patients who achieved American College of Rheumatology 20% response was significantly higher with olokizumab every 2 (63.6%) and 4 (70.4%) weeks vs placebo (25.9%; both P < .0001). Most treatment-emergent adverse events were mild to moderate.
Study details: Findings are from CREDO 1 , a phase 3 trial of 428 patients with active RA despite treatment with methotrexate who were randomly assigned to receive subcutaneous olokizumab 64 mg once every 2 or 4 weeks or placebo with continuation of background methotrexate.
