OBJECTIVES: Study the efficacy and safety of mycophenolate mofetil (MMF) combined with methotrexate (MTX) compared to cyclophosphamide (CYC) followed by azathioprine (AZA) to treat active Takayasu arteritis (TAK).
METHODS: Adults with active TAK were randomised in a 2:1 ratio to receive oral MMF plus MTX or intravenous CYC followed by oral AZA. All subjects also received high-dose oral glucocorticoids with a predefined taper. The primary endpoint was overall response rate at week 52, defined as achieving a complete response (CR) or partial response (PR). Secondary endpoints included rates of CR and PR at weeks 28 and 52.
RESULTS: A total of 111 patients with TAK were enrolled: 74 in the MMF+MTX group and 37 in the CYC/AZA group, with comparable baseline demographic and clinical features. The overall response rates at 28 and 52 weeks were 58.1% and 55.4% in the MMF+MTX group, respectively, higher than 32.4% at both time points in the CYC/AZA group (P = .011 and .022). CR and PR rates at 28 and 52 weeks were also higher in the MMF+MTX group. Relapse occurred in 4 patients in the MMF+MTX group and 2 in the CYC/AZA group. One serious adverse event, neutropenia with fever, occurred in 1 patient in the CYC/AZA group.
CONCLUSIONS: Treatment of active TAK with MMF+MTX has more favourable efficacy compared to CYC/AZA. These findings provide evidence to use the combination of MTX and MMF, 2 generally well-tolerated and inexpensive therapies, to treat TAK.
