AbstractThe objective of this study is to evaluate the efficacy and safety of rhTNFR:Fc: a recombinant tumor necrosis factor receptor:Fc fusion protein compared with methotrexate (MTX) in patients with rheumatoid arthritis in China. We treated 238 patients with active rheumatoid arthritis with either twice weekly subcutaneous injection rhTNFR:Fc (25 mg) or weekly oral MTX (mean 15 mg per week) for 24 weeks (registration number: 2003L01264). Clinical responses were defined as the percent improvement in disease activity according to the criteria of the American College of Rheumatology (ACR-N). As compared with MTX-treated patients, more patients who received rhTNFR:Fc had ACR20 improvement in disease activity during the first 2 weeks (P < 0.05). Similarly, more patients treated with rhTNFR:Fc having ACR20, ACR50, ACR70 improvement in disease activity during 8 weeks (P < 0.05). At the end of 12-week treatment, patients received rhTNFR:Fc also had significant improvement at ACR20 (P < 0.05). Compared with oral MTX, patients received rhTNFR:Fc also had significant improvement at ACR70 at the end of 24 weeks treatment (P < 0.05). In conclusion, compared with oral MTX subcutaneous injection, rhTNFR:Fc acted more rapidly to release symptoms and signs of active RA in Chinese patients, and well tolerated in patients with rheumatoid arthritis in China.
