A recent study has reviewed biologic therapies for ulcerative colitis (Ann Intern Med. 2014;160(10):704-711). Here’s the abstract link: bit.ly/1o5PpRX .

Data Synthesis: ..There were 7 double-blind, placebo-controlled trials that were rated as low risk of bias and showed that all biological agents (adalimumab, golimumab, infliximab, and vedolizumab) resulted in more clinical responses, clinical remissions, and mucosal healings than placebo for induction therapy. The results of network meta-analysis suggested that infliximab is more effective to induce clinical response (odds ratio, 2.36 [95% credible interval, 1.22 to 4.63]) and mucosal healing (odds ratio, 2.02 [95% credible interval, 1.13 to 3.59]) than adalimumab. No other indirect comparison reached statistical significance. For maintenance, 6 double-blind, placebo-controlled trials that were rated high risk of bias showed that all biological agents have greater clinical efficacy than placebo. The occurrence of adverse events was not different between biological agents and placebo.

Limitation: Few trials, no head-to-head comparisons, and inadequate follow-up in maintenance trials.

Conclusion: Biological agents are effective treatments for UC, but head-to-head trials are warranted to establish the best therapeutic option.
