Dataset Information

A clinical decision support tool may help to optimise vedolizumab therapy in Crohn's disease.

ABSTRACT:

Background

A clinical decision support tool (CDST) has been validated for predicting treatment effectiveness of vedolizumab (VDZ) in Crohn's disease.

Aim

To assess the utility of this CDST for predicting exposure-efficacy and disease outcomes.

Methods

Using data from three independent datasets (GEMINI, GETAID and VICTORY), we assessed clinical remission rates and measured VDZ exposure, rapidity of onset of action, response to dose optimisation and progression to surgery by CDST-defined response groups (low, intermediate and high).

Results

A linear relationship existed between CDST-defined groups, measured VDZ exposure, rapidity of onset of action and efficacy in GEMINI through week 52 (P < 0.001 at all time points across three CDST-defined groups). In GETAID, CDST predicted differences in clinical remission at week 14 (AUC = 0.68) and rapidity of onset of action (P = 0.04) between probability groups. The high-probability patients did not benefit from shortening of infusion intervals, and differences in onset of action between the high-intermediate and low-probability groups within GETAID were no longer significant when including low-probability patients who received a week 10 infusion. CDST predicted a twofold increase in surgery risk over 12 months of VDZ therapy among low- to intermediate-probability vs high-probability patients (adjusted HR 2.06, 95% CI 1.33-3.21).

Conclusions

We further extended the clinical utility of a previously validated VDZ CDST, which accurately predicts at baseline exposure-efficacy relationships and rapidity of onset of action and could be used to help identify patients who would most benefit from interval shortening and those most likely to require surgery while on active therapy.

Project description:BackgroundDespite advancements in the therapeutic armamentarium for Crohn's disease (CD), biologic and small molecule monotherapies are associated with sub-optimal response and remission rates. Utilizing dual biologic therapy (DBT) holds the potential to increase efficacy in the treatment of refractory or partially responsive CD. Evidence pertaining to this strategy remains limited.MethodsWe retrospectively examined refractory CD patients treated with a combination of ustekinumab and vedolizumab. Outcomes to DBT at week (wk) 52 were compared to monotherapy. The primary outcome constituted corticosteroid-free remission. Secondary outcomes included adverse events, infections, hospitalizations, surgeries, treatment persistence, and disease clearance.ResultsSixteen of 21 active refractory CD patients (76%) on DBT achieved disease remission at wk 52. Mucosal healing was observed in 38% (n = 6), biochemical remission in 25% (n = 4), and both clinical and biochemical remission in 38% (n = 6). Of these patients, 50% (n = 8) achieved corticosteroid-free remission. Three patients (37.5%) with corticosteroid-free remission achieved complete disease clearance. Paired median fecal calprotectin decreased from 508 to 118 µg/g (P < .0001). Paired C-reactive protein median decreased from 1.04 to 0.50 mg/dL (P < .0001). Median Harvey Bradshaw Index score reduced from 7 to 2 (P = .003). Endoscopic healing was achieved with a paired simple endoscopic score for CD decrease from 6 to 3 (P = .013). Corticosteroid dependency reduced from 17 to 8 patients discontinuing altogether. Patients still requiring corticosteroids experienced a decrease in average daily dose from 9 to 6 mg (P = .045). At wk 52, 5 patients (24%) did not meet the criteria for remission with 4 requiring CD-related surgical intervention. Mean CD-related hospitalizations reduced from 2.95 ± 2.33 to 0.52 ± 1.12 (P < .001) and surgeries from 1.76 ± 1.3 to 0.14 ± 0.4 (P < .001). Three infections with 1 requiring hospitalization and 1 report of headache were noted. Two patients discontinued DBT.ConclusionsDual biologic therapy with ustekinumab and vedolizumab is a safe and effective strategy to induce disease remission in refractory CD. Large-scale studies are necessary to validate findings in a prospective setting.

Project description:BackgroundDirect comparisons are lacking between vedolizumab and tumour necrosis factor (TNF)-antagonist therapy in Crohn's disease (CD).AimTo compare safety and effectiveness of vedolizumab and TNF-antagonist therapy in adult CD patients.MethodsRetrospective observational cohort (May 2014-December 2017) propensity score-weighted comparison of vedolizumab vs TNF-antagonist therapy (infliximab, adalimumab, certolizumab) in CD. Propensity scores were weighted for age, prior treatments, disease complications, extent and severity, steroid dependence, and concomitant immunosuppressive drug use. The primary outcome was comparative risk for infections or non-infectious serious adverse events (requiring antibiotics, antivirals, antifungals, hospitalisation, or treatment discontinuation, or resulting in death). Secondary comparative effectiveness outcomes were clinical remission (resolution of CD-related symptoms), steroid-free clinical remission and endoscopic remission (absence of ulcers/erosions).ResultsWe included 1266 patients (n = 659 vedolizumab). Rates of non-infectious serious adverse events (odds ratio [OR] 0.072, 95% confidence interval [CI] 0.012-0.242), but not serious infections (OR 1.183, 95% CI 0.786-1.795), were significantly lower with vedolizumab vs TNF-antagonist therapy. Safety comparisons for non-infectious serious adverse events remained significant after adjusting for differences in duration of exposure. No significant difference was observed between vedolizumab and TNF-antagonist therapy for clinical remission (hazard ratio [HR] 0.932, 95% CI 0.707-1.228), steroid-free clinical remission (HR 1.250, 95% CI 0.677-2.310) or endoscopic remission (HR 0.827, 95% CI 0.595-1.151). TNF-antagonist therapy was associated with higher treatment persistence compared with vedolizumab.ConclusionsThere was a lower risk of non-infectious serious adverse events, but not serious infections, with vedolizumab vs TNF-antagonist therapy, with no significant difference for achieving disease remission.
