  Purpose

The purpose of the study is to evaluate the improvements in signs and symptoms of rheumatoid arthritis (RA) for fostamatinib compared to placebo or adalimumab in patients who are Disease-Modifying anti-rheumatic drug (DMARD) naïve, DMARD intolerant or have had an inadequate response to DMARDs. The study will last for approximately six months

Primary Outcome Measures:
  • DAS28 score change from baseline to week 6 compared to placebo (DAS28 = Disease Activity Score based on a 28 joint count) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • DAS28 score change from baseline to week 24 compared to adalimumab [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Review of efficacy based on the following criteria: DAS28, DAS28 response criteria, ACR20, ACR50, ACR70, ACR-N [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    (ACR20 = American College of Rheumatology 20% response criteria) ACR50 = American College of Rheumatology 50% response criteria, ACR70 = American College of Rheumatology 70% response criteria, ACR N = numeric index of the ACR response)

  • Health Assessment Questionnaire - Disability Index (HAQ-DI). [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • 36-item Short Form Health Survey (SF-36) questionnaire [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Detailed Description:

Sub-study:

Full title: Optional Genetic Research

Date: 10 September 2010

Version: 1

Objectives: To collect and store, with appropriate consent , DNA samples for future exploratory research into genes/genetic variation that may influence response (ie, absorption, distribution, metabolism and excretion, safety, tolerability and efficacy) to fostamatinib disodium and/or adalimumab; and/or susceptibility to, progression of and prognosis of RA

The main study recruitment is complete, and sub study recruitment will continue until the target is reached, estimated to be June 2013

Full title: (Sub-study to OSKIRA-4): A Phase IIB, Multi-Centre, Randomised, Double-Blind, Placebo-Controlled, Parallel Group Study of the Efficacy and Safety of Fostamatinib Disodium Monotherapy Compared with Placebo or Adalimumab Monotherapy in Patients with Active Rheumatoid Arthritis: Magnetic Resonance Imaging Sub-Study

Date: 21 March 2011

Version: 1

Primary objective: Assess the efficacy of fostamatinib in reducing joint synovial disease activity as measured by:
