Background & aims

We compared the efficacy and safety of different first-line (biologic-naïve) and second-line (prior exposure to tumor necrosis factor [TNF] antagonists) agents for treatment of moderate to severely active ulcerative colitis in a systematic review and network meta-analysis.

Methods

We searched publication databases through September 30, 2019, for randomized trials of adults with moderate to severe ulcerative colitis treated with TNF antagonists, vedolizumab, tofacitinib, or ustekinumab, as first-line or second-line agents, compared with placebo or another active agent. Efficacy outcomes were induction and maintenance of remission and endoscopic improvement; safety outcomes were serious adverse events and infections. We performed a fixed-effects network meta-analysis using the frequentist approach, and calculated odds ratios (ORs) and 95% CI values. Agents were ranked using surface under the cumulative ranking (SUCRA) probabilities. Overall quality of evidence was rated using GRADE (Grading of Recommendations, Assessment, Development and Evaluation).

Results

In biologic-naïve patients, infliximab was ranked highest for induction of clinical remission (OR vs placebo, 4.07; 95% CI, 2.67-6.21; SUCRA, 0.95) and endoscopic improvement (SUCRA, 0.95) (moderate confidence in estimates [CE]). In patients with prior exposure to TNF antagonists, ustekinumab (SUCRA, 0.87) and tofacitinib (SUCRA, 0.87) were ranked highest for induction of clinical remission and were superior to vedolizumab (ustekinumab vs vedolizumab: OR, 5.99; 95% CI, 1.13-31.76 and tofacitinib vs vedolizumab: OR, 6.18; 95% CI, 1.003-8.00; moderate CE) and adalimumab (ustekinumab vs adalimumab: OR, 10.71; 95% CI, 2.01-57.20 and tofacitinib vs adalimumab: OR, 11.05; 95% CI, 1.79-68.41; moderate CE). Vedolizumab had the lowest risk of infections (SUCRA, 0.81), followed by ustekinumab (SUCRA, 0.63) in maintenance trials.

Conclusions

In a systematic review and network meta-analysis, we found infliximab to be ranked highest in biologic-naïve patients, and ustekinumab and tofacitinib were ranked highest in patients with prior exposure to TNF antagonists, for induction of remission and endoscopic improvement in patients with moderate to severe ulcerative colitis. More trials of direct comparisons are needed to inform clinical decision making with greater confidence.
