Higher Trough Vedolizumab Concentrations During Maintenance Therapy are Associated With Corticosteroid-Free Remission in Inflammatory Bowel Disease.

ABSTRACT: BACKGROUND AND AIMS:Vedolizumab is an anti-?4?7 biologic approved for ulcerative colitis [UC] and Crohn's disease [CD]. We aimed to examine the association of maintenance vedolizumab concentrations with remission. METHODS:We performed a cross-sectional multi-centre study of inflammatory bowel disease [IBD] patients on maintenance vedolizumab. A homogeneous mobility shift assay [HMSA] was used to determine trough serum concentrations of vedolizumab and anti-drug antibodies [ATVs]. The primary outcome was corticosteroid-free clinical and biochemical remission defined as a composite of clinical remission, normalized C-reactive protein [CRP] and no corticosteroid use in 4 weeks. Secondary outcomes included corticosteroid-free endoscopic and deep remission. Vedolizumab concentrations were compared between patients in remission and with active disease. Logistic regression, adjusting for confounders, assessed the association between concentrations and remission. RESULTS:In total, 258 IBD patients were included [55% CD and 45% UC]. Patients in clinical and biochemical remission had significantly higher vedolizumab concentrations [12.7 µg/mL vs 10.1 µg/mL, p = 0.002]. Concentrations were also higher among patients in endoscopic and deep remission [14.2 µg/mL vs 8.5 µg/mL, p = 0.003 and 14.8 µg/mL vs 10.1 µg/mL, p = 0.01, respectively]. After controlling for potential confounders, IBD patients with vedolizumab concentrations >11.5 µg/mL were nearly 2.4 times more likely to be in corticosteroid-free clinical and biochemical remission. Only 1.6% of patients had ATVs. CONCLUSIONS:In a large real-world cohort of vedolizumab maintenance concentrations, IBD patients with remission defined by objective measures [CRP and endoscopy] had significantly higher trough vedolizumab concentrations and immunogenicity was uncommon.

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.

Project description:BackgroundCorticosteroid-free clinical remission is important in ulcerative colitis.ObjectiveThis GEMINI 1 post hoc analysis evaluated vedolizumab efficacy in achieving sustained corticosteroid-free clinical remission in moderately to severely active ulcerative colitis.Materials and methodsGEMINI 1 included a 6-week induction period followed by a 46-week maintenance period. Patients received stable corticosteroid dosing at baseline/during induction and tapered dosing during maintenance. Analysis groups included vedolizumab (induction and maintenance); vedolizumab/placebo (vedolizumab induction, placebo maintenance); and placebo (induction and maintenance). The primary endpoint was sustained corticosteroid-free clinical remission (partial Mayo score ≤2, no individual subscore >1, for ≥32 weeks). Multivariate analyses identified covariates associated with the primary endpoint. Safety endpoints included adverse events.ResultsBaseline demographics and concomitant corticosteroid use were similar across groups (n=454). A greater proportion (95% confidence interval) of the vedolizumab group achieved sustained corticosteroid-free clinical remission (10.2% [6.9 to 13.6]) vs the placebo group (1.4% [0.0 to 7.3]; difference 8.9% [-3.8 to 21.4]). Proportions were similar between the vedolizumab/placebo and placebo groups. Covariates associated with sustained corticosteroid-free clinical remission (odds ratio [95% confidence interval]) were treatment (vedolizumab vs placebo: 9.35 [1.25 to 71.43]; p=0.0605), anti-tumor necrosis factor alpha exposure (yes vs no: 0.26 [0.12 to 0.57]; p=0.0008), and disease duration (≤2 vs >2 years: 2.66 [0.99-7.19]; p=0.0531). Adverse events were similar across groups.ConclusionA numerically greater proportion of vedolizumab-treated patients with ulcerative colitis achieved sustained corticosteroid-free clinical remission. Vedolizumab treatment, no previous anti-tumor necrosis factor alpha exposure, and shorter disease duration were associated with sustained corticosteroid-free clinical remission.ClinicaltrialsgovNCT00783718.
