There is no controlled trial of parenteral methotrexate (MTX) in ulcerative colitis (UC). We conducted a prospective, controlled, randomized, double-blind trial of intra-muscular or subcutaneous MTX at a dose of 25mg/week vs placebo in patients with steroid-dependent UC.


Eligible patients had active or inactive UC and were on prednisone at a daily dose of 10 to 40 mg at inclusion. Exclusion criteria were resistance to oral steroids, need for colectomy, alcohol consumption, pulmonary, renal or liver disease, obesity or diabetes mellitus, pregnant or breast-feeding female subjects, infection with HIV, HBV, HCV, a past history of malignant condition, use of other immunosuppressants within 1 month prior to inclusion or anti-TNF treatment within 2 months prior to inclusion. The primary endpoint was success at week 16 as defined by a Mayo score < or = 2 with no item >1, complete steroid withdrawal with a forced tapering regimen, and no need for other IS, anti TNF or colectomy. Secondary endpoints were success at week 24, success at week 16 and 24, mucosal healing (Mayo endoscopic subscore = 0 or 1), clinical remission (Mayo clinical subscore < or =χ2 with no item>1) without steroids and no need for other IS, anti TNF or colectomy at week 16 and/or 24. Endpoints were compared using chi square tests. The analysis was performed on an intent-to-treat basis. We expected a success rate of 45% with methotrexate and 20% with placebo. One hundred and ten patients were deemed sufficient to show a statistically significant difference with a 80% power and an alpha risk of 5% (bilateral test).


One hundred and eleven patients (59 male, median age 42) were included in 26 European centers: 60 were randomized to the MTX arm and 51 to the placebo arm. Median dose of prednisone was 25 mg/d at inclusion. Rates of success at week 16 were 32% of patients among patients given MTX vs 20% among patients given placebo (difference 12.1% [CI 95%: -4.0%; +28.1%]; p=0.15). Clinical remission without steroids and no need for other IS, anti TNF or colectomy at week 16 was observed in 42% of patients given MTX vs 23.5% of patients given placebo (difference 18.1% [IC 95%: 1.1%; 35.2%]; p=0.04). The other secondary endpoints were not significant. Mucosal healing was observed in 35% of patients given MTX vs 25.5% of patients given placebo (difference 9.5% [CI 95%: -7.5% ; + 26.5]; p= 0.28). Rates of serious adverse events were 10% in the MTX group and 6% in the placebo group (p =0.5).

Treatment with parenteral MTX was not significantly superior to placebo for the primary endpoint. However it induced clinical remission without steroids in a significantly larger percentage of patients with steroid dependent UC than placebo.
