Recruitment & Eligibility

Status: ot Recruiting

Sex: All

Target Recruitment: 1000

Inclusion Criteria

1) Age = 18 years
2) A diagnosis of rheumatoid arthritis according to the American College of Rheumatology (ACR1987 classification) of at least six months’ duration from diagnosis at screening
3) Active disease at the time of screening as defined by:
- = 6 swollen joints (of 66 joints assessed)
and
- = 6 tender joints (of 68 joints assessed)
and
20 mm on the patient’s global VAS disease score
and
DAS28=3.2 (based on ESR)
Note: The swollen and tender joint counts will be re-assessed at baseline (Visit 2) to ensure these eligibility criteria are fulfilled prior to randomization. Where possible joint count reassessment must be performed at the baseline visit (Visit 2); if this is not feasible it can be done =3 days prior to visit 2.
4) RA functional class I, II or III
5) Treatment with 1 non-biologic DMARD for at least 12 weeks and at a stable dose for at least 4 weeks prior to Visit 2 (please refer to table 9 for permitted DMARDs)
6) Following receipt of verbal and written information about the study, the patient must provide signed informed consent before any study related activity including wash-out of other drug products is carried out
France: In France, a patient will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category.
