We evaluated the real-world effectiveness and safety of ustekinumab (UST) in patients with Crohn's disease (CD).This study used a retrospective, multicenter, multinational consortium UST-treated CD patients. Data included patient demographics, phenotype, activity, treatment history, concomitant medications. Cumulative rates clinical, steroid-free, endoscopic, radiographic remissions were assessed using time-to-event analysis, clinical predictors by multivariate Cox proportional hazard...

Abstract Background We studied the efficacy and safety of ustekinumab (UST) vs adalimumab (ADA) through 1 year in biologic-naïve patients (pts) with moderate-to-severe Crohn’s disease. Methods SEAVUE was a multicenter, randomized, blinded, parallel-group, active-controlled study adults CD Activity Index (CDAI) scores ≥220/≤450. Biologic-naïve pts failing/intolerant to conventional therapy any size ulcer on baseline (BL) ileocolonoscopy were eligible. Pts randomized 1:1 UST (⁓6mg/kg IV at BL...

Abstract Background Perianal fistulas are common and cause significant quality of life impairment in patients (pts) with Crohn’s disease (CD). In previous phase 2/3 studies, ustekinumab (UST) showed some evidence efficacy on fistula resolution, no clear dose-response relationship. Additional studies needed to evaluate the role UST perianal treatment. Here, we report data from two recent CD, SEAVUE STARDUST. Methods SEAVUE, biologic-naïve pts moderate-to-severe CD were randomized receive...

To estimate long-term persistence among bio-naïve patients with CD initiated on ustekinumab or adalimumab.Adults initiating adalimumab (index date, between September 23, 2016 and August 1, 2019) were sampled from the IBM MarketScan Commercial Database. Patients without CD-indicated biologics (bio-naïve) no diagnoses for other autoimmune diseases 12 months pre-index date (baseline) included. Cohorts balanced baseline characteristics inverse probability of treatment weighting. Persistence was...

Our hypothesis states that variceal pressure and wall tension increase dramatically during esophageal peristaltic contractions. This in is a natural consequence of the anatomy physiology esophagus venous plexus. The purpose this study was to evaluate hemodynamics contraction. A simultaneous ultrasound probe manometry catheter placed distal nine patients with varices. Simultaneous luminal images varices were recorded Maximum cross-sectional area pressures at which varix flattened, closed,...

In UNITI-1 and 2, pivotal induction studies of ustekinumab (UST) in patients with CD, 467 non-responders to UST 130 mg or ~6 mg/kg IV received 90 SC at Week 8. Overall, 50.5% achieved response 16 (delayed responders, DR).1 We sought characterise DR population induced identify predictors for delayed response. 2 who were UST~6 had a dose 8 included this post hoc analysis classified as 8-responders (ER), (no 8/response 16) (NR, no Weeks 16).

<h3>Introduction</h3> Perianal fistulas are common and cause significant quality of life impairment in patients (pts) with Crohn's disease (CD). We report data on fistula closure from the SEAVUE STARDUST studies. <h3>Methods</h3> In SEAVUE, biologic-naïve pts moderately-to-severely active CD were randomized to blinded UST (∽6 mg/kg IV at baseline then 90mg SC q8w) or adalimumab (ADA; 160/80 mg baseline/W2, 40mg q2w).
