Last Updated: 2011-10-03

Results Overview

Participant Flow

The first participant enrolled on 01 July 2008, and the last participant completed the study on 08 April 2009. Participants were recruited from 61 centres in 14 countries in Europe, Southern Africa and South America.

Male or female adult patients with active rheumatoid arthritis (on background treatment of methotrexate) were randomly assigned to receive AZD5672 at 20, 50, 100 or 150 mg once daily, placebo or etanercept. It was planned to randomise approx 360 patients in total, 60 to the open-label etanercept arm and 300 in total to the AZD5672 or placebo arms.

SECONDARY outcome

Timeframe: Baseline to 12 Weeks

Change from baseline in the DAS28 composite score (a measure of RA symptoms including: joint swelling and tenderness; patient's assessment of disease activity; and ESR) after 12 Weeks' treatment. A change of zero indicates no effect of treatment and a negative change of 1.2 indicates a clinically important improvement in symptoms. The DAS scale runs from 0 to 10, with the higher scores indicating worse RA symptoms.

SECONDARY outcome

Timeframe: Baseline to 12 Weeks

Change from baseline in HAQ-DI (a measure of patients assessment of physical function scored between zero and 3) after 6 months' treatment, calculated as score at 12 Weeks minus score at baseline. A change of zero indicates no effect of treatment and a negative change of 0.22 or greater indicates an improvement in symptoms. The HAQ-DI scale runs from 0 to 3, with higher scores indicating greater disability.
