The safety of vedolizumab for ulcerative colitis and Crohn's disease

Abstract

Objective: Vedolizumab is a gut-selective antibody to α4β7 integrin for the treatment of ulcerative colitis (UC) and Crohn's disease (CD). We report an integrated summary of the safety of vedolizumab.

Design: Safety data (May 2009-June 2013) from six trials of vedolizumab were integrated. Adverse events were evaluated in patients who received ≥1 dose of vedolizumab or placebo and were reported as exposure-adjusted incidence rates as the number of patients experiencing the event per 100 person-years (PYs) of exposure. Predictors of serious infection were assessed using a Cox proportional hazards model.

Results: In total, 2830 patients had 4811 PYs of vedolizumab exposure (median exposure range, 1-1977 days). No increased risk of any infection or serious infection was associated with vedolizumab exposure. Serious clostridial infections, sepsis and tuberculosis were reported infrequently (≤0.6% of patients). No cases of progressive multifocal leucoencephalopathy were observed. Independent risk factors for serious infection in UC were prior failure of a tumour necrosis factor α antagonist (HR, 1.99; 95% CIs 1.16 to 3.42; p=0.0122) and narcotic analgesic use (HR, 2.68; 95% CI 1.57 to 4.58; p=0.0003), and in CD were younger age (HR, 0.97; 95% CI 0.95 to 0.98; p<0.0001), corticosteroid (HR, 1.88; 95% CI 1.35 to 2.63; p=0.0002) or narcotic analgesic use (HR, 2.72; 95% CI 1.90 to 3.89; p<0.0001). Investigator-defined infusion-related reactions were reported for ≤5% of patients in each study. Eighteen vedolizumab-exposed patients (<1%) were diagnosed with a malignancy.

Conclusions: Vedolizumab has a favourable safety profile with low incidence rates of serious infections, infusion-related reactions and malignancies over an extended treatment period.

Patient distribution within the overall safety population. The overall safety population includes all patients who received ≥1 dose of study drug in the six studies. The phase 3 safety population includes patients from the phase 3 GEMINI studies only. Patients randomised to PBO in GEMINI 1, GEMINI 2 or GEMINI 3 and who enrolled into GEMINI LTS received open-label VDZ in that study. Thus, VDZ-exposed patients may also have been exposed to PBO. CD, Crohn's disease; LTS, long-term safety; PBO, placebo; PD, pharmacodynamics; PK, pharmacokinetics; UC, ulcerative colitis; VDZ, vedolizumab. aOne enrolled patient randomised to VDZ was not dosed. bIncludes 38 and 421 VDZ-naïve patients who enrolled directly into C13004 or GEMINI LTS, respectively. cIncludes data collected from 22 May 2009 to 27 June 2013.
