Introduction
The efficacy and safety of vedolizumab, a gut-selective α4β7 integrin antibody, were demonstrated in the GEMINI 1 and GEMINI 2 clinical trials of adults aged 18–80 years. We investigated the efficacy and safety of vedolizumab in patients stratified by age from the GEMINI trials.
Methods
Safety and efficacy, including clinical response, clinical remission, and corticosteroid-free remission, at week 6 and/or 52 were determined post hoc in patients aged <35, 35 to <55, and ≥55 years.
Results
At baseline, 353, 412, and 130 ulcerative colitis (UC) and 582, 443, and 90 Crohn’s disease (CD) patients were aged <35, 35 to <55, and ≥55. Of these patients, 56 were aged ≥65 years (UC: 33, CD: 23). Trends favoring vedolizumab over placebo were observed for most efficacy endpoints irrespective of patient age; some variability between subgroups was observed. Safety profiles of vedolizumab and placebo were similar in all age groups. Vedolizumab-treated patients aged ≥55 had the lowest incidence of serious infections (0.9 per 100 person–years) and adverse events leading to hospitalization (14.8 per 100 person–years). There were no age-related differences in the incidence of adverse hematological events, malignancy, or death.
Conclusions
The safety and efficacy of vedolizumab in patients with UC or CD were similar for all age groups. The number of patients in the oldest age group in these analyses was small; thus further studies of vedolizumab in larger cohorts of elderly patients are warranted.
