Safety Profile of Biologic Drugs in the Therapy of Ulcerative Colitis: A Systematic Review and Network Meta-Analysis.

We compared the safety profile of biologic drugs in patients with moderately to severely active ulcerative colitis (UC). A systematic literature search was performed using Medline (PubMed), Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases through February 9, 2016. We included randomized controlled trials (RCTs) that compared the safety of biologic drugs (infliximab, adalimumab, golimumab, and vedolizumab) with one another or with placebo in patients with UC. Two reviewers independently conducted the search and selection of studies and rated the risk of bias in each trial. The network meta-analysis (NMA) was conducted for an induction phase (6-8 weeks) and maintenance phase (52-54 weeks) with a Bayesian hierarchical random effects model in Aggregate Data Drug Information System (ADDIS) software. The PROSPERO registration number was CRD42016032607. Seven RCTs were included in the systematic review with NMA. In the case of the induction phase, the NMA could be conducted for the assessment of the relative safety profile of adalimumab, golimumab, and vedolizumab, and in the case of the maintenance phase of infliximab, adalimumab, golimumab, and vedolizumab. The methodological quality of the included RCTs was evaluated as low risk of bias, but high risk of bias in the case of attrition bias (incomplete outcome data) according to the Cochrane criteria. No significant differences were found in the rate of adverse events in patients treated with the reviewed biologics. Vedolizumab was most likely to have the most favorable safety profile in the induction phase as was infliximab for the maintenance phase. The assessment of the relative safety profile revealed no significant differences between the biologic drugs. Further studies are needed to confirm our findings including head-to-head comparisons between the analyzed biologics.

Safety profile of biologic drugs in the therapy of Crohn disease: A systematic review and network meta-analysis.

Crohn disease (CD) is an inflammatory bowel disease which occurs especially in developed countries of Western Europe and North America. The aim of the study was to compare the safety profile of biologic drugs in patients with CD. A systematic literature search was performed using PubMed, Embase, and CENTRAL databases, until April 27, 2016. We included randomized controlled trials (RCTs) that compared the safety of biologic drugs (infliximab, adalimumab, vedolizumab, certolizumab pegol, and ustekinumab) with one another or with placebo in patients with CD. The network meta-analysis (NMA) was conducted for an induction phase (6-10 weeks) and maintenance phase (52-56 weeks) with a Bayesian hierarchical random effects model in the ADDIS® software. The PROSPERO registration number was CRD42016032606. Ten RCTs were included in the systematic review with NMA. In the case of the induction phase, the NMA could be conducted for the assessment of the relative safety profile of adalimumab, vedolizumab, certolizumab pegol, and ustekinumab, and in the case of the maintenance phase-of infliximab, adalimumab, and vedolizumab. There were no significant differences in the rate of adverse events in patients treated with biologics. Statistical analysis revealed that vedolizumab had the greatest probability of being the safest treatment in most endpoints in the induction phase and adalimumab-in the maintenance phase. No significant differences between the biologics in the relative safety profile analysis were observed. Further studies are needed to confirm our findings, including head-to-head comparisons between the analyzed biologics.
