Efficacy and safety of biologics and small molecule drugs for patients with moderate-to-severe ulcerative colitis: a systematic review and network meta-analysis
Abstract
BACKGROUND
There is a growing armamentarium for the treatment of moderate-to-severe ulcerative colitis. We aimed to compare the relative efficacy and safety of biologics and small molecule drugs for the treatment of patients with moderate-to-severe ulcerative colitis.
METHODS
In this systematic review and network meta-analysis, we searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials without language restrictions for articles published between Jan 1, 1990, and July 1, 2021. Major congresses' databases from Jan 1, 2018, to July 3, 2021, were reviewed manually. Phase 3, placebo-controlled or head-to-head randomised controlled trials (RCTs) assessing the efficacy and safety of biologics or small molecule drugs as induction or maintenance therapies for patients with moderate-to-severe ulcerative colitis were included. Phase 2 RCTs were excluded because of their small sample sizes and inclusion of doses not further explored in phase 3 RCTs. Summary data from intention-to-treat analyses were extracted from included reports by JSL and PAO. The primary outcome was the induction of clinical remission. A network meta-analysis was done under the frequentist framework, obtaining pairwise odds ratios (ORs) and 95% CIs. The surface under the cumulative ranking (SUCRA) was used to rank the included agents for each outcome. Higher SUCRA scores correlate with better efficacy, whereas lower SUCRA scores correlate with better safety. Maintenance data on efficacy for…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 10 participants or records.
