E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy of 2 oral dosing regimens of fostamatinib (Regimen A - 100 mg twice daily (bid); Regimen B - induction with 100 mg bid for the first 4 weeks, 150 mg once daily (qd) maintenance thereafter) taken in combination with methotrexate, compared with placebo plus methotrexate, in patients with active rheumatoid arthritis (RA) who have had inadequate response to a single tumour necrosis factor-alpha (TNF-α) antagonist. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study are: •To further assess the efficacy of fostamatinib measured by ACR20, ACR 50% response criteria (ACR50), ACR 70% response criteria (ACR70), ACR-N and the individual components of the ACR score. •To assess physical function status of patients after administration of fostamatinib using the Health Assessment Questionnaire - Disability Index (HAQ-DI). •To evaluate the efficacy of fostamatinib as measured by Disease Activity Score based on a 28 joint count (DAS28) and DAS28 European League Against Rheumatism (EULAR) response criteria. •To investigate the effects of fostamatinib on patient reported health outcomes measures. •To assess the efficacy of fostamatinib in the prevention of structural joint damage, as measured by change in radiographic modified total Sharp score (mTSS) and the components of mTSS at Week 24.
