Real World Clinical Effectiveness and Safety of Ozanimod in the Treatment of Ulcerative Colitis: 1-Year Follow-Up from a Tertiary Center.

BACKGROUND: Ozanimod is a first-in-class Sphingosine-1-phosphate (S1P) receptor modulator approved for the treatment of moderately to severely active ulcerative colitis (UC). Real world data describing use of ozanimod are limited. AIM: To provide 1-year follow-up results of our UC patient cohort treated with ozanimod. METHODS: This prospective, observational cohort study includes consecutive patients who initiated ozanimod at the University of Chicago IBD Center between 5/2021 and 12/2022. We collected demographic, clinical, and laboratory data. Clinical disease activity was prospectively assessed using the Simple Clinical Colitis Activity Index. RESULTS: Forty-five patients with UC initiated ozanimod therapy and were included in the effectiveness analysis. The median age was 35 years (interquartile range (IQR) 28-52), median disease duration of 6 years (IQR 3-13), 26 (58%) were male, 23 (51%) had extensive colitis, 34 (76%) had previous advanced therapy exposure. Thirty-four patients had clinically active UC at the time of ozanimod initiation; week 10 clinical response and remission rates were 58% and 53%, respectively. By week 52, the rates were 25% for both clinical response and remission. In the 12 (39%) patients with a > 75% reduction in absolute lymphocyte count, numerically greater induction clinical response and remission rates were observed (80% vs 54%, p = 0.4 and 75% vs 53%, p = 0.4, respectively). There were no episodes of symptomatic bradycardia and no other new safety signals. CONCLUSION: Ozanimod effectively induced clinical response and remission patients with largely treatment refractory UC, however, had modest long-term effectiveness. The safety profile was favorable with no new signals.

Upadacitinib Is Effective and Safe in Both Ulcerative Colitis and Crohn's Disease: Prospective Real-World Experience.

BACKGROUND & AIMS: Upadacitinib is a novel selective Janus kinase 1 inhibitor that has shown efficacy in the treatment of moderate to severe ulcerative colitis (UC) and Crohn's disease (CD), and has received Food and Drug Administration approval for UC. We report a large real-world experience with upadacitinib in UC and CD. METHODS: We performed a prospective analysis of clinical outcomes on upadacitinib in patients with UC and CD using predetermined intervals at weeks 0, 2, 4, and 8 as part of a formalized treatment protocol at our institution. We used the Simple Clinical Colitis Activity Index and the Harvey-Bradshaw index, as well as C-reactive protein and fecal calprotectin to assess efficacy, and also recorded treatment-related adverse events and serious adverse events. RESULTS: A total of 105 patients were followed up for 8 weeks on upadacitinib, 84 of whom (44 UC patients, 40 CD patients) were initiated because of active luminal or perianal disease and included in the analysis. One hundred percent previously received anti-tumor necrosis factor therapy, and 89.3% had received 2 or more advanced therapies. At 4 and 8 weeks of treatment for UC, 19 of 25 (76.0%) and 23 of 27 (85.2%) achieved clinical response and 18 of 26 (69.2%) and 22 of 27 (81.5%) achieved clinical remission, respectively. Of those who previously were tofacitinib-exposed, 7 of 9 (77.8%) achieved clinical remission by 8 weeks. In CD, 13 of 17 (76.5.%) achieved clinical response and 12 of 17 (70.6%) achieved clinical remission by 8 weeks. Of those with increased fecal calprotectin and C-reactive protein levels, 62% and 64% normalized by week 8, respectively. Results were seen as early as week 2 in both UC and CD, with clinical remission rates of 36% and 56.3.%, respectively. Acne was the most commonly reported adverse event, occurring in 24 of 105 patients (22.9%). CONCLUSIONS: In this large real-world experience in medically resistant patients with UC or CD, we report that upadacitinib is rapidly effective and safe, including in those who had prior tofacitinib exposure. This study was approved by the Institutional Review Board at the University of Chicago (IRB20-1979).

The Arrival of Intestinal Ultrasound for Inflammatory Bowel Disease Care in the United States.

Intestinal ultrasound (IUS) is a noninvasive and highly reliable point-of-care tool to evaluate inflammation of the bowel. It offers comparable accuracy to endoscopy and magnetic resonance enterography. Although IUS has been incorporated into the management of inflammatory bowel disease (IBD) in other parts of the world, it has only recently arrived in the United States. However, barriers to integration of IUS into IBD care in the United States have included a lack of adoption by leading centers, lack of educational opportunities, and an unclear path for remuneration. This article provides information about the use of IUS in IBD, reviews the data comparing existing modalities of assessment of IBD with IUS, and summarizes strategies to overcome existing barriers to IUS implementation, including the newly available US-based training pathway and appropriate billing practice.

At-home Disease Monitoring by Patient-performed Intestinal Ultrasound in Severe Ulcerative Colitis.

We describe the first reported case of a nonmedically trained patient using a handheld ultrasound device to monitor his ulcerative colitis in real time at home during induction therapy for severe colitis.
