* either serum C-reactive protein more than 2 mg/dl or ESR no less than 28 mm at 1 hour, with adequate safety profiles)
* be ACR functional class I-III
* have been receiving MTX 6 mg/week for a minimum of 3 months at a stable dose for at least 4 weeks at the time of study enrollment

Exclusion Criteria:

* the start of dose increment of PSL equivalents within 3 months of the study enrollment
* experience of antirheumatic therapy except for MTX and PSL equivalents
