OP34 Efficacy and safety of advanced induction and maintenance therapies in patients with moderately to severely active Ulcerative Colitis: An indirect treatment comparison using Bayesian network meta-analysis
Abstract
The therapeutic armamentarium to treat adult patients with moderately to severely active ulcerative colitis (UC) continues to evolve. With this rapid innovation, the comparative efficacy and safety of more recent advanced therapies remain unknown.
Bayesian network meta-analysis was used to indirectly compare the efficacy and safety of advanced therapies for induction (6–10 weeks) and maintenance (44–54 weeks post-induction response) in adults with moderately-to-severely active UC. Efficacy was assessed separately in bio-naïve and bio-exposed populations by clinical remission (Full Mayo score [FM] of ≤2 with no subscore >1), clinical response (decrease from baseline in FM ≥3 points and ≥30% with decrease in rectal bleeding score [RBS] of ≥1 or absolute RBS ≤1) and endoscopic improvement (endoscopic score ≤1); ad hoc analyses were conducted on upadacitinib (UPA) RCT data to produce FM outcomes. Safety was assessed by discontinuation due to adverse events (AEs), serious AEs, and serious infections. Induction therapies included UPA 45 mg, adalimumab 160/80 mg, filgotinib 100 and 200 mg, golimumab 200/100 mg, infliximab 10 and 5 mg/kg, ozanimod 0.92 mg, tofacitinib 10 mg, ustekinumab (UST) 6 mg/kg, and vedolizumab (VED) 300 mg. The maintenance analysis included low and high maintenance doses of these therapies. Phase 3 randomized controlled trials (RCTs) were identified via systematic literature review. Random effects models were used to account for expected heterogeneity in…
