Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this study is to evaluate the long-term safety and tolerability of fostamatinib in patients with active rheumatoid arthritis (RA) by assessment of adverse event (AE) reports, laboratory safety data, vital signs, electrocardiograms (ECGs) and physical examination.;Secondary Objective: The secondary objectives of the study are: •To assess the long-term efficacy of fostamatinib as measured by: -Signs and symptoms of RA, as measured by components of American College of Rheumatology (ACR) response criteria and Disease Activity Score based on a 28 joint count (DAS28) score. -Structural joint damage, as measured by radiographic modified total Sharp score (mTSS) and components of mTSS. •To assess physical function status of patients after administration of fostamatinib using the Health Assessment Questionnaire - Disability Index (HAQ-DI). •To investigate the effects of fostamatinib on patient reported health outcomes as measured by the 36-item Short Form Health Survey (SF-36).;Primary end point(s): As this is an extension study, no endpoints have been defined.
