Shorter Disease Duration Is Associated With Higher Rates of Response to Vedolizumab in Patients With Crohn's Disease But Not Ulcerative Colitis.
Background & aimsPatients with Crohn's disease (CD), but not ulcerative colitis (UC), of shorter duration have higher rates of response to tumor necrosis factor (TNF) antagonists than patients with longer disease duration. Little is known about the association between disease duration and response to other biologic agents. We aimed to evaluate response of patients with CD or UC to vedolizumab, stratified by disease duration.MethodsWe analyzed data from a retrospective, multicenter, consortium of patients with CD (n = 650) or UC (n = 437) treated with vedolizumab from May 2014 through December 2016. Using time to event analyses, we compared rates of clinical remission, corticosteroid-free remission (CSFR), and endoscopic remission between patients with early-stage (≤2 years duration) and later-stage (>2 years) CD or UC. We used Cox proportional hazards models to identify factors associated with outcomes.ResultsWithin 6 months initiation of treatment with vedolizumab, significantly higher proportions of patients with early-stage CD, vs later-stage CD, achieved clinical remission (38% vs 23%), CSFR (43% vs 14%), and endoscopic remission (29% vs 13%) (P < .05 for all comparisons). After adjusting for disease-related factors including previous exposure to TNF antagonists, patients with early-stage CD were significantly more likely than patients with later-stage CD to achieve clinical remission (adjusted hazard ratio [aHR], 1.59; 95% CI, 1.02-2.49), CSFR (aHR, 3.39; 95% CI, 1.66-6.92), and endoscopic remission (aHR, 1.90; 95% CI, 1.06-3.39). In contrast, disease duration was not a significant predictor of response among patients with UC.ConclusionsPatients with CD for 2 years or less are significantly more likely to achieve a complete response, CSFR, or endoscopic response to vedolizumab than patients with longer disease duration. Disease duration does not associate with response vedolizumab in patients with UC

Changes in Vedolizumab Utilization Across US Academic Centers and Community Practice Are Associated With Improved Effectiveness and Disease Outcomes.
BACKGROUND:Vedolizumab effectiveness estimates immediately after Food and Drug Administration (FDA) approval for ulcerative colitis (UC) and Crohn\u27s disease (CD) are limited by use in refractory populations. We aimed to compare treatment patterns and outcomes of vedolizumab in 2 time frames after FDA approval. METHODS:We used 2 data sets for time trend analysis, an academic multicenter vedolizumab consortium (VICTORY) and the Truven MarketScan database, and 2 time periods, May 2014-June 2015 (Era 1) and July 2015-June 2017 (Era 2). VICTORY cumulative 12-month clinical remission, corticosteroid-free remission, and mucosal healing rates, and Truven 12-month hospitalization and surgery rates, were compared between Eras 1 and 2 using time-to-event analyses. RESULTS:A total of 3661 vedolizumab-treated patients were included (n = 1087 VICTORY, n = 2574 Truven). In both cohorts, CD and UC patients treated during Era 2 were more likely to be biologic naïve. Compared with Era 1, Era 2 CD patients in the VICTORY consortium had higher rates of clinical remission (31% vs 40%, P = 0.03) and mucosal healing (42% vs 58%, P \u3c 0.01). These trends were not observed for UC. In the Truven database, UC patients treated during Era 2 had lower rates of inflammatory bowel disease-related hospitalization (22.4% vs 9.6%, P \u3c 0.001) and surgery (17.2% vs 9.4%, P = 0.008), which was not observed for CD. CONCLUSION:Since FDA approval, remission and mucosal healing rates have increased for vedolizumab-treated CD patients, and vedolizumab-treated UC patients have had fewer hospitalizations and surgeries. This is likely due to differences between patient populations treated immediately after drug approval and those treated later
Retrospective Analysis of Safety of Vedolizumab in Patients With Inflammatory Bowel Diseases.
BACKGROUND & AIMSThere are few real-world data on the safety of vedolizumab for treatment of Crohn\u27s disease (CD) or ulcerative colitis (UC). We quantified rates and identified factors significantly associated with infectious and non-infectious adverse events in clinical practice.METHODSWe performed a retrospective review of data from a multi-center 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.RESULTSOur 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.CONCLUSIONIn 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
Predictors and Management of Loss of Response to Vedolizumab in Inflammatory Bowel Disease
Background: We quantified loss of response (LOR) to vedolizumab (VDZ) in clinical practice and assessed the effectiveness of VDZ dose intensification for managing LOR.Methods: Retrospective review (May 2014-December 2016) of a prospectively maintained inflammatory bowel disease (IBD) registry. Kaplan-Meier estimates were used to determine rates of LOR to VDZ . Independent predictors of LOR were identified using univariate and multivariable Cox proportional hazard regression. Success of recapturing response (\u3e50% reduction in symptoms from baseline) and remission (complete resolution of symptoms) after dose intensification was quantified.Results: Cumulative rates for VDZ LOR were 20% at 6 months and 35% at 12 months, with slightly lower rates in Crohn\u27s disease than in ulcerative colitis (6 months 15% vs 18% and 12 months 30% vs 39%, P = 0.03). On multivariable analysis, LOR to a tumor necrosis factor (TNF) antagonist before VDZ use was associated with an increased risk for LOR to VDZ [hazard ratio (HR) 1.93; 95% confidence interval (CI) 1.25-2.97] in all patients. For Crohn\u27s disease patients specifically, higher baseline C-reactive protein concentration was associated with increased risk for LOR to VDZ (HR 1.01 per mg/dL increase, 95% CI 1.01-1.02). Shortening of VDZ infusion interval from 8 to every 4 or 6 weeks recaptured response in 49% and remission in 18% of patients.Conclusions: LOR to a TNF antagonist before VDZ use and higher baseline C-reactive protein are important predictors of VDZ LOR. Treatment response can be recaptured in almost half of these patients with VDZ infusion interval shortening
