Background and Aims: Vedolizumab is a gut-selective a4ß7 integrin antagonist therapy for ulcerative colitis and Crohn's disease. The GEMINI long-term safety [LTS] trial is an ongoing open-label study investigating the safety of vedolizumab. We present interim exploratory analyses of efficacy in patients with Crohn's disease. Methods: Patients from the C13004, GEMINI 2 and GEMINI 3 studies and vedolizumab-naïve patients could enrol in GEMINI LTS and received vedolizumab every 4 weeks. Data were collected from May 22, 2009 to June 27, 2013. Outcomes of clinical response and remission, defined by the Harvey-Bradshaw Index, and health-related quality of life [HRQL] were assessed for up to 152 weeks of treatment in the efficacy population. Results: Among patients with response at week 6 in GEMINI 2 who received vedolizumab continuously, 83% [n=100/120] and 89% [n=62/70] of patients with available data were in remission after 104 and 152 weeks, respectively. Increased dosing frequency from every 8 weeks [GEMINI 2] to every 4 weeks [GEMINI LTS] improved outcomes in patients who had withdrawn early from GEMINI 2, with 47% [n=27/57] experiencing clinical response and 32% [n=18/57] in remission at week 52 of GEMINI LTS [up from 39% and 4% before the dose increase]. Similar improvements were observed regardless of prior tumour necrosis factor [TNF] antagonist exposure. Long-term benefits of HRQL were also observed. Conclusions: The clinical benefits of vedolizumab continued with long-term treatment regardless of prior TNF antagonist exposure. Increased dosing frequency might improve outcomes in patients who lose response to conventional 8-weekly dosing.
