Background: Corticosteroid-free clinical remission is important in ulcerative colitis.
Objective: This GEMINI 1 post hoc analysis evaluated vedolizumab efficacy in achieving sustained corticosteroid-free clinical remission in moderately to severely active ulcerative colitis.
Materials and Methods: GEMINI 1 included a 6-week induction period followed by a 46-week maintenance period. Patients received stable corticosteroid dosing at baseline/during induction and tapered dosing during maintenance. Analysis groups included vedolizumab (induction and maintenance); vedolizumab/placebo (vedolizumab induction, placebo maintenance); and placebo (induction and maintenance). The primary endpoint was sustained corticosteroid-free clinical remission (partial Mayo score ≤ 2, no individual subscore > 1, for ≥ 32 weeks). Multivariate analyses identified covariates associated with the primary endpoint. Safety endpoints included adverse events.
Results: Baseline demographics and concomitant corticosteroid use were similar across groups (n=454). A greater proportion (95% confidence interval) of the vedolizumab group achieved sustained corticosteroid-free clinical remission (10.2% [6.9 to 13.6]) vs the placebo group (1.4% [0.0 to 7.3]; difference 8.9% [– 3.8 to 21.4]). Proportions were similar between the vedolizumab/placebo and placebo groups. Covariates associated with sustained corticosteroid-free clinical remission (odds ratio [95% confidence interval]) were treatment (vedolizumab vs placebo: 9.35 [1.25 to 71.43]; p=0.0605), anti-tumor necrosis factor alpha exposure (yes vs no: 0.26 [0.12 to 0.57]; p=0.0008), and disease duration (≤ 2 vs > 2 years: 2.66 [0.99– 7.19]; p=0.0531). Adverse events were similar across groups.
Conclusion: A numerically greater proportion of vedolizumab-treated patients with ulcerative colitis achieved sustained corticosteroid-free clinical remission. Vedolizumab treatment, no previous anti-tumor necrosis factor alpha exposure, and shorter disease duration were associated with sustained corticosteroid-free clinical remission.
