Abstract
Background It is unknown which maintenance therapy is the most effective option for patients admitted for an acute severe ulcerative colitis (ASUC) episode responding to intravenous steroids.
Methods We conducted a multicentre, parallel-group, open-label randomised controlled trial among 23 French centres in thiopurine and biologics-naïve adults admitted for ASUC responding to intravenous steroids. Eligible patients were randomly assigned to receive infliximab (IFX) and azathioprine (AZA) with a 7-day steroid tapering scheme (IFX+AZA arm) or AZA and conventional standardised steroid tapering regimen (AZA arm). The primary composite endpoint was treatment failure at week 52, defined as the absence of steroid-free clinical remission, the absence of endoscopic response, the use of a prohibited treatment for relapse, severe adverse event leading to treatment interruption, colectomy or death. Multiple imputation for missing data was performed.
Findings Among the 64 patients randomised (Lichtiger score 13.5±2.0; median age of 34.5 (P25–P75 26.3–50.3) years, median C reactive protein of 29.0 (12.8–96.8) mg/L at baseline): 32 were assigned to the IFX+AZA arm and 32 to the AZA arm. In the ITT population, treatment failure at week 52 was observed in 22/27 (81.5%) in the AZA arm and 16/30 (53.3%) in the IFX+AZA arm (risk ratio 3.85, 95% CI (1.15 to 12.88), p=0.03). 29 adverse events were severe, including 13 disease exacerbations, 6 severe infections without any difference between both arms.
Interpretation Combination therapy with IFX+AZA was more effective at 1 year than AZA alone to avoid treatment failure in patients with ASUC responding to intravenous steroids.
