Trial Outcomes & Findings for Study to Examine Efficacy and Safety of Rituximab in Participants With Rheumatoid Arthritis (NCT NCT02699892)

NCT ID: NCT02699892

Last Updated: 2016-10-26

Results Overview

DAS28 score is a measure of participant's disease activity calculated using tender joint count \[28 joints\] (TJC28), swollen joint count \[28 joints\] (SJC28), participant's global assessment of disease activity (PGH) \[visual analog scale (VAS): 0=no disease activity to 100=maximum disease activity\] and erythrocyte sedimentation rate (ESR). DAS28 was calculated according to following formula: \[0.56 multiplied by (\*) square root (√) of TJC\] plus (+) \[0.28\*√SJC\]+\[0.70\*the natural logarithm (ln) ESR\]+\[0.014\*PGH\]. Total possible score of 0 to approximately 10, where higher scores represented higher disease activity. Scores below 2.6 indicated clinical remission, score of less than or equals to (\</=) 3.2 indicated low disease activity, score of greater than (\>) 3.2 to \</=5.1 indicated moderate disease activity, scores above 5.1 indicated high or severe disease.

SECONDARY outcome

Timeframe: Baseline, Weeks 24, 48 and 72

Population: ITT Population. Here, "number of participants analyzed" signified those participants who were evaluable for this outcome and "n" signified those participants who were evaluable for a specified time point.

Clinical response was assessed according to EULAR categorical DAS28 response criteria, which defined clinically meaningful improvement at Weeks 24, 48, and 72. EULAR response was based on change from baseline (CFB) in DAS28 score and on actual DAS28 score, at Weeks 24, 48, and 72. DAS28 score: participant's disease activity calculated using TJC28, SJC28, PGH \[VAS: 0=no disease activity to 100=maximum disease activity\] and ESR. DAS28 was calculated by following formula: (0.56\*√TJC)+(0.28\*√SJC)+(0.70\*ln ESR)+(0.014\*PGH). Total possible score = 0-10, higher scores represented higher disease activity. EULAR Good response: DAS28\</=3.2; reduction of DAS28 \>1.2.
