  • The Efficacy and Safety of Recombinant Human Tumor Necrosis Factor-α Receptor Ⅱ: IgG Fc Fusion Protein for Treatment of Rheumatoid Arthritis

    ObjectiveTo investigate the efficacy and safety of recombinant human tumor necrosis factor-α receptor Ⅱ:IgG Fc fusion protein (rhTNFR:Fc) for treatment of active rheumatoid arthritis (RA). MethodsThis study included 86 patients with active rheumatoid arthritis treated between September 2011 and January 2013. They were divided into two groups randomly. Forty-three patients in the treatment group received rhTNFR:Fc (25 mg, twice a week) by subcutaneous injection and methotrexate (MTX) (10 mg, orally once a week), and the other 43 patients in the contrast group received MTX (10 mg, orally once a week), hydroxychloroquine (100 mg, orally twice daily), and leflunomide (10 mg, orally once daily). The clinical efficacy of the treatments 12 weeks later were compared between the two groups. American College of Rheumatology (ACR) 20, 50, and 70 evaluation criteria were used for efficacy evaluation. ResultsThe ACR 20, 50 and 70 effective rates in 4, 8 and 12 weeks after the treatment in the treatment group were significantly higher than those in the control group (P<0.05). The seven indicators including the duration of morning stiffness, joint tenderness index, joint swelling index, erythrocyte sedimentation rate, C-reactive protein, platelets and rheumatoid factors within 12 weeks after treatment were significantly improved in both the two groups, and the improvements in the treatment group were more significant (P<0.05). There was no significant difference in the incidence of adverse drug reactions between the two groups (P>0.05). ConclusionRhTNFR:Fc is effecive and safe in treating active RA.
