Efficacy of biological therapies and small molecules in moderate to severe ulcerative colitis: systematic review and network meta-analysis
Abstract
Objective Biological therapies and small molecules continue to be evaluated in moderate to severely active ulcerative colitis, but are often studied in placebo-controlled trials, meaning their relative efficacy and safety is unknown. We examined this in a network meta-analysis. Design We searched the literature to October 2021 to identify eligible trials. We judged efficacy using clinical remission, endoscopic improvement, or clinical response, and according to previous exposure or non-exposure to antitumour necrosis factor (TNF)-α therapy. We also assessed safety. We used a random effects model and reported data as pooled relative risks (RRs) with 95% CIs. Interventions were ranked according to their P-score. Results We identified 28 trials (12 504 patients). Based on failure to achieve clinical remission, upadacitinib 45 mg once daily ranked first versus placebo (RR 0.73; 95% CI 0.68 to 0.80, P-score 0.98), with infliximab 5 mg/kg and 10 mg/kg second and third, respectively. Upadacitinib ranked first for clinical remission in both patients naïve to anti-TNF-α drugs (RR 0.69; 95% CI 0.61 to 0.78, P-score 0.99) and previously exposed (RR 0.78; 95% CI 0.72 to 0.85, P-score 0.99). Upadacitinib was superior to almost all other drugs in these analyses. Based on failure to achieve endoscopic improvement infliximab 10 mg/kg ranked first (RR 0.61; 95% CI 0.51 to 0.72, P-score 0.97), with upadacitinib 45 mg once daily, second, and infliximab 5 mg/kg third. Upadacitinib was more…
