2. Has a Functional Capacity Classification of I-III (as described in Appendix E of the protocol).

3. Has been stable on oral MTX therapy (5 to 25 mg administered as a single weekly dose) for at least 12 weeks.

4. Has RA activity at screening and at baseline (Day 1, pre-morning dose), defined as a 28-joint disease activity score (DAS28) of =3.2 and a change in DAS28 score from screening to baseline that is >0 and =1.2 (baseline minus screening).

5. Between 18 and 65 years of age inclusive.

6. Is able to give voluntary written informed consent to participate in this trial.
