Arms Assigned Interventions
Experimental: leflunomide
Leflunomide 10-20 mg/d
Drug: leflunomide

Leflunomide 10-20 mg, orally, once daily for up to 48 weeks. Twelve weeks after the initial Leflunomide induction, patients were randomized into two groups (LEF+CTX:LEF+MTX=2:1) if the DAS 28 were higher than 2.6, or continuing leflunomide use without dosing change. Then, the disease activity was assessed using DAS 28 every 12 weeks. The regimen should remain unchanged if the DAS 28 reached to less than 2.6, otherwise, a third (24 weeks) or fourth (36 weeks) DMARs should be added.

Intravenous CTX was administrated once 200-400mg per 3 weeks.

Active Comparator: methotrexate
MTX 7.5-15 mg/week
Drug: methotrexate

MTX 7.5-15 mg, orally, once weekly for up to 48 weeks. Twelve weeks after the initial MTX induction, patients were randomized into two groups (MTX+CTX:LEF+MTX=2:1) if the DAS 28 were higher than 2.6, or continuing MTX use without dosing change. Then, the disease activity was assessed using DAS 28 every 12 weeks. The regimen should remain unchanged if the DAS 28 reached to less than 2.6, otherwise, a third (24 weeks) or fourth (36 weeks) DMARs should be added.

Intravenous CTX was administrated once
