Abstract
Objective To compare the relative efficacy of ustekinumab (UST) vs. other therapies for 1-year response and remission rates in patients with moderate-severe UC.Methods Randomized controlled trials reporting induction and maintenance efficacy of anti-TNFs (infliximab [IFX], adalimumab [ADA], golimumab [GOL]), vedolizumab (VDZ), tofacitinib (TOF) or UST were identified through a systematic literature review (SLR). Analyses were conducted for clinical response, clinical remission and endoscopic-mucosal healing for populations with and without failure of prior biologics (non-biologic failure [NBF]; biologic failure [BF]). Maintenance data from trials with re-randomized response designs were re-calculated to correspond to treat-through arms. Bayesian network meta-analyses (NMA) were conducted to obtain posterior distribution probabilities for UST to perform better than comparators.Results Six trials included NBF patients and four included BF patients. In NBF patients, UST as a 1-year regimen showed higher probabilities of clinical response, remission and endoscopic-mucosal healing vs. all treatments: Bayesian probabilities of UST being better than active therapies ranged from 91% (VDZ) to 100% (ADA) for response; 82% (VDZ) to 99% (ADA) for remission and 82% (IFX) to 100% (ADA and GOL) for endoscopic-mucosal healing. In BF patients, UST was the most effective treatment (Q8W dose); however, effect sizes were smaller than in the NBF population.Conclusions Results indicate a higher likelihood of response, remission and endoscopic-mucosal healing at 1 year with UST vs. comparators in the NBF population. In BF patients, a higher likelihood of response to UST vs. the most comparators was also observed, although results were more uncertain.
