Outcome results

Primary

Percentage of Patients Who Had at Least 1 Adverse Event in Any Category

Time frame: Entry in extension to study termination (variable duration; maximum 52 weeks)

Population: The full analysis set was the primary population for reporting efficacy and safety data, and comprised all patients who received at least 1 dose of investigational product.

Secondary

Components of ACR Response Criteria Over Time

ACR = American College of Rheumatology, n/a = not applicable, PO = orally, QD = once daily

Time frame: Every 12 weeks for one year then every 24 weeks until study end

Population: Insufficient data were available for analysis due to sparse data collection and the early termination of the study.

Secondary

DAS28-CRP Score Over Time

CRP = C-reactive protein, DAS28 = disease activity score based on a 28 joint count, n/a = not applicable, PO = orally, QD = once daily

Time frame: Every 12 weeks for one year then every 24 weeks until study end

Population: Insufficient data were available for analysis due to sparse data collection and the early termination of the study.

Secondary

HAQ-DI Score Over Time

HAQ-DI = health assessment questionnaire - disability index, n/a = not applicable, PO = orally, QD = once daily

Time frame: Every 12 weeks for one year then every 24 weeks until study end

Population: Insufficient data were available for analysis due to sparse data collection and the early termination of the study.

Time frame: Every 12 weeks for one year then yearly until study end

Population: Insufficient data were available for analysis due to sparse data collection and the early termination of the study.
