Abstract:
Background/Aims:A subgroup analysis was conducted in Japanese patients with moderate to severe ulcerative colitis (UC) enrolled in the phase 3 VISIBLE 1 study, which evaluated the safety and efficacy of a new vedolizumab subcutaneous (SC) formulation.
Methods:Eligible patients received open-label infusions of vedolizumab 300 mg intravenous (IV) at weeks 0 and 2 in the induction phase. Patients with clinical response by complete Mayo score at week 6 entered the double-blind maintenance phase and were randomized to vedolizumab 108 mg SC every 2 weeks, placebo, or vedolizumab 300 mg IV every 8 weeks. The primary endpoint was clinical remission (complete Mayo score ≤ 2 points; no individual subscore > 1 point) at week 52.
Results:Of 49 patients who entered the induction phase, 22 out of 49 patients (45%) had clinical response at week 6 and were randomized to vedolizumab 108 mg SC (n = 10), placebo (n = 10), or vedolizumab 300 mg IV (n = 2). At week 52, 4 out of 10 patients (40%) who received vedolizumab SC had clinical remission versus 2 out of 10 patients (20%) who received placebo (difference: 20% [95% confidence interval, –27.9 to 61.8]). Two patients (2/10, 20%) who received vedolizumab SC experienced an injection-site reaction versus none who received placebo.
Conclusions:Our results indicate that the efficacy of vedolizumab SC in a subgroup of Japanese patients with UC are similar with those in the overall VISIBLE 1 study population, and with those established with vedolizumab IV. The safety and tolerability of vedolizumab SC were generally similar to that established for vedolizumab IV. (ClinicalTrials.gov ID NCT02611830; EudraCT 2015-000480-14)
