Retrospective Analysis of Safety of Vedolizumab in Patients With Inflammatory Bowel Diseases.

ABSTRACT: BACKGROUND & AIMS:There are few real-world data on the safety of vedolizumab for treatment of Crohn's disease (CD) or ulcerative colitis (UC). We quantified rates and identified factors significantly associated with infectious and non-infectious adverse events in clinical practice. METHODS:We performed a retrospective review of data from a multicenter consortium database (from May 2014 through June 2017). Infectious and non-infectious adverse events were defined as those requiring antibiotics, hospitalization, vedolizumab discontinuation, or resulting in death. Rates were quantified as proportions and events per 100 patient years of exposure (PYE) or follow up (PYF). We performed multivariable logistic regression analyses to identify factors significantly associated with events and reported as odds ratios (OR) with 95% CIs. RESULTS:Our analysis comprised 1087 patients (650 with CD and 437 with UC; 55% female; median age, 37 years) with 861 PYE and 955 PYF. Infections were observed in 68 patients (6.3%; 7.9 per 100 PYE, 7.1 per 100 PYF); gastrointestinal infections (n = 31, 2.4 per 100 PYE, 2.2 per 100 PYF) and respiratory infections (n = 14, 1.6 per 100 PYE, 1.5 per 100 PYF) were the most common. Arthralgias were the most common non-infectious adverse events (n = 31, 2.9%; 3.6 per 100 PYE). Two patients developed malignancies (squamous cell skin cancer and colorectal cancer; 0.23 per 100 PYE, 0.21 per 100 PYF). Active smoker status (OR, 3.39) and number of concomitant immunosuppressive agents (corticosteroids or immunomodulators; OR, 1.72 per agent) used were independently associated with infections. CONCLUSION:In a retrospective cohort study of patients with IBD, we found vedolizumab to be well tolerated with an overall favorable safety profile. Active smoking and concomitant use of immunosuppressive agents were independently associated with infections.

Project description:Background: Vedolizumab (vedo) is effective for induction and maintenance of remission in adults with inflammatory bowel disease (IBD). Pediatric data are still limited, especially for the youngest children with very early onset disease (VEO-IBD). The aim of this study was to assess the safety and efficacy of vedo in VEO-IBD. Methods: We performed a retrospective review of pediatric IBD patients with VEO-IBD (defined as aged <6 years) receiving vedo. Data on demographics, disease behavior, activity, and previous treatments/surgeries were collected. Disease activity was assessed using the pediatric Crohn's disease (CD) activity index (PCDAI) for CD or pediatric ulcerative colitis (UC) activity index (PUCAI) for UC. Primary outcome was clinical response after induction therapy with vedolizumab (4th dose week). It was defined as a decrease in PCDAI of at least 12.5 points between baseline and 4th dose week for CD, and a decrease in PUCAI of at least 20 points between baseline and this time for UC. Descriptive statistics were performed to analyze the data. Results: The study included 16 patients with VEO-IBD who have received vedo: 4/16 (25%) with CD, and 12/16 (75%) with UC at the median age of diagnosis 33.7 months (6.6 months-4.5 years). Median age at vedo initiation was 6.5 years (2.2-16.5 years). Among the analyzed individuals, 56.25% had failed more than one anti-tumor necrosis factor (TNF) alfa agent. Clinical response at 4th dose week was observed in 9/16 (56.3%) patients: mean baseline PCDAI score was 34.4 ± 1.9 and 10.6 ± 1.8 after induction therapy with vedo, while PUCAI score was 26 ± 6 vs. 18 ± 8, respectively. There was improvement in patients' nutritional state: at baseline 2/16 (12.5%) children had body mass index (BMI) below 1 percentile and no child had such BMI after induction therapy with vedo. No infusion reactions or serious adverse events/infections were reported. Conclusion: Vedolizumab is safe and effective in the medical management of pediatric patients with VEO-IBD.

Project description:ImportanceObservational comparative effectiveness studies can inform the positioning of biologic therapies for older patients with inflammatory bowel disease (IBD) who are underrepresented in clinical trials.ObjectiveTo compare the effectiveness and safety of vedolizumab vs tumor necrosis factor (TNF) for older patients with IBD.Design, setting, and participantsThis active comparator, new-user design, comparative effectiveness study was conducted between January 1, 2005, and December 31, 2018, among 754 older patients (aged ≥50 years) with IBD from the Danish National Patient Register. The mean follow-up after treatment initiation took place at 32 to 40 weeks. Statistical analysis was performed from February 1 to April 27, 2022.InterventionsTreatment with vedolizumab or TNF antagonists.Main outcomes and measuresThe primary effectiveness outcome was treatment failure, defined as the composite risk of IBD-related hospitalization, IBD-related surgery, or a new corticosteroid prescription more than 6 weeks after initiation of treatment with biologic therapy. Secondary effectiveness outcomes were time to each individual component of the composite effectiveness outcome. The primary safety outcome was the risk of serious infections, defined as infections requiring hospitalization. A 1:1 propensity score-matched analysis was conducted, accounting for patient-, disease-, and treatment-associated factors.ResultsThe study compared 377 older patients with IBD with incident use of vedolizumab (202 women [53.6%]; mean [SD] age, 61.2 [8.3] years; 177 [46.9%] with Crohn disease) vs 377 patients with incident use of TNF antagonists (206 women [54.6%]; mean [SD] age, 61.3 [8.1] years; 182 [48.3%] with Crohn disease). Overall, vedolizumab was associated with an increased risk of treatment failure compared with TNF antagonists (1-year risk, 45.4% vs 34.7%; adjusted hazard ratio [HR], 1.31; 95% CI, 1.02-1.69), including higher risk of IBD-related hospitalization (1-year risk, 27.8% vs 16.3%; adjusted HR, 1.48; 95% CI, 1.03-2.15) and IBD-related major abdominal surgery (1-year risk, 21.3% vs 8.0%; adjusted HR, 2.39; 95% CI, 1.45-3.94). In subgroup analysis by IBD phenotype, among patients with Crohn disease, vedolizumab was associated with a 77% higher risk of treatment failure (adjusted HR, 1.77; 95% CI, 1.21-2.58), while no difference in risk of treatment failure was seen among patients with ulcerative colitis (adjusted HR, 1.04; 95% CI, 0.75-1.43; P = .03 for interaction). There was no significant difference in the risk of serious infections, overall (1-year risk, 8.2% vs 8.7%; adjusted HR, 1.04; 95% CI, 0.58-1.85) and by IBD phenotype.Conclusions and relevanceIn this comparative effectiveness study of older patients with IBD, vedolizumab was associated with a higher risk of treatment failure compared with TNF antagonists, particularly among patients with Crohn disease, without offering a significant safety advantage.

Project description:BACKGROUND:There has been limited evaluation of the association between vedolizumab trough concentration and clinical outcomes in patients with inflammatory bowel diseases (IBD). AIM:To perform a systematic review and meta-analysis to evaluate the potential role of therapeutic drug monitoring (TDM) for vedolizumab. METHODS:Through a systematic literature search through 28 February 2019, we identified five cohort studies (558 patients, 42% with ulcerative colitis) reporting the association between vedolizumab trough concentration and clinical outcomes in patients with IBD. We calculated mean difference (MD) in vedolizumab trough concentration in patients achieving vs not achieving clinical outcomes, and qualitatively synthesized thresholds associated with favourable outcomes. RESULTS:In patients with UC, median vedolizumab trough concentrations were consistently higher in patients achieving clinical remission (median, 14.3 ?g/mL vs 10.5 ?g/mL; MD, 5.1 ?g/mL, 95% CI, 2.8-7.4) or endoscopic remission (median, 13.0 ?g/mL vs 9.7; MD, 5.1 ?g/mL, 95% CI, 2.2-7.9). In patients with CD, there was no significant difference in median vedolizumab trough concentrations in patients achieving vs not achieving clinical remission (MD, 2.0 ?g/mL; 95% CI, -0.5 to 4.5) or endoscopic remission (MD, 3.6 ?g/mL; 95% CI, -1.4 to 8.6). In patients with UC, week 6 vedolizumab trough concentrations ?18.5-20.8 ?g/mL, and maintenance trough concentrations ?9.0-12.6 ?g/mL were associated with favourable clinical outcomes. Antibodies to vedolizumab were reported in 1.7%-3.0% patients on maintenance therapy. CONCLUSION:Based on meta-analysis, patients with UC who achieve endoscopic and clinical remission have significantly higher vedolizumab trough concentration during maintenance therapy. Vedolizumab trough concentration >20 ?g/mL at week 6, and >12 ?g/mL during maintenance may be associated with better outcomes, though cause-effect relationship remains unclear. Prospective studies on reactive and proactive therapeutic drug monitoring of vedolizumab (vs empiric dose escalation) are warranted.
