MAUI, HAWAII – The effectiveness of methotrexate in psoriatic arthritis is a matter of debate, but Dr. Arthur Kavanaugh is a believer based in part upon a recent subanalysis of the TICOPA study.
Moreover, his new 5-year follow-up analysis from the GO-REVEAL study of golimumab (Simponi) with or without concomitant methotrexate suggests that methotrexate plus the tumor necrosis factor inhibitor provided synergistic efficacy, he said at the 2016 Rheumatology Winter Clinical Symposium.
The 5-year analysis doesn’t provide definitive proof of synergistic benefit because it wasn’t designed or powered with that endpoint in mind (Arthritis Care Res. 2016;68[2]:267–74). No randomized trial completed to date has been. But the first-ever trial set up to test the synergistic efficacy hypothesis is underway. It’s a 52-week, double-blind, multicenter, randomized trial of etanercept (Enbrel) and methotrexate versus either alone in combination with placebo. And while the Amgen-sponsored study won’t be completed until 2018, Dr. Kavanaugh is ready to predict the outcome based in part upon the message contained in his GO-REVEAL findings.
