Moderately Active Rheumatoid Arthritis

Brief summary

The primary endpoint is the mean change in DAS28-CRP, from baseline to day 43, of CIT-013 the 50 mg CIT-013 and 100 mg CIT-013 arms pooled, compared to placebo.

Mean change in DAS28-CRP, from baseline to day 85, per arm of the originally assigned treatment., 3.1. Proportion of ACR20, ACR50, ACR707 responders, from baseline to day 43, per arm of the originally assigned treatment. 3.2. Proportion of ACR20, ACR50, ACR70 responders, from baseline to day 85, per arm of the originally assigned treatment., 3.3. Proportion of participants reaching low disease activity, defined as DAS28-CRP equal or less than 3.2, from baseline to day 43 and day 85, per arm of the originally assigned treatment. 3.4.
