Evaluation of Long-term Safety and Effectiveness of Fostamatinib in the Treatment of Rheumatoid Arthritis (RA)

Mean DAS28-CRP Score

DAS28-CRP: Disease Activity Score based on a count of swollen and tender joints (out of 28 joints), blood test measures of inflammation (CRP) and the patient's own assessment. Scores can take any positive value with a lower value indicating a better clinical condition. Number of participants are those with data at entry to this study (Week 0). As no imputation was applied, the numbers at subsequent visits are lower. bid = twice daily, CRP = C-reactive protein, qd = once daily

Time frame: Weeks 0, 12, 24, 36 and 52

Mean mTSS Score

mTSS: modified total sharp score, a measure of structural progression based upon X-rays. Hand and foot joints are scored for erosions and joint space narrowing and the results summed to give a value between 0 and 488. A higher value represents more serious progression of the disease. Number of participants are those with data at entry to this study (Week 0). As no imputation was applied, the numbers at subsequent visits are lower. bid = twice daily, N/A = not applicable, qd = once daily

Time frame: Weeks 0 and 52

Mean HAQ-DI Score

HAQ-DI: Health Assessment Questionnaire - Disability Index, a measure of physical function. The HAQ-DI score is then calculated by summing the category scores from 8 sub-categories (ie, scores for patient ability in dressing and grooming, rising, eating, walking, hygiene, reach, grip and common daily activities) and dividing by the number of categories completed. The HAQ-DI score takes values between 0 and 3, with a higher score indicating greater disability. Number of participants are those with data at entry to this study (Week 0). As no imputation was applied, the numbers at subsequent visits are lower. bid = twice daily, qd = once daily
