To compare the efficacy and safety of Tripterygium wilfordii Hook F (TwHF) and methotrexate (MTX) for postmenopausal women with active rheumatoid arthritis (RA), a multicenter, randomized controlled trial will be conducted. Three hundred postmenopausal women with active RA will be randomly allocated (1:1) to treatment with TwHF 20mg thrice daily and MTX 10 mg once a week for 24 weeks, or MTX plus dummy TwHF. The primary outcome is the percentage of participants with American College of Rheumatology 20% at week 24.
This study is a multicenter, randomized, double-blinded, controlled trial with two parallel arms. The aim of the study is to evaluate whether Tripterygium wilfordii Hook F combined with methotrexate (MTX) might be better than MTX alone for postmenopausal women with active rheumatoid arthritis (RA).
