An overview of ozanimod as a therapeutic option for adults with moderate-to-severe active ulcerative colitis

Cardiovascular Safety of Ozanimod in Patients With Ulcerative Colitis: True North and Open-Label Extension Analyses

BACKGROUND & AIMS

Evaluating cardiovascular safety of sphingosine 1-phosphate (S1P) receptor modulators is warranted due to S1P receptor expression on cardiomyocytes and vascular endothelial cells. This analysis reports the cardiovascular safety of ozanimod, an S1P receptor modulator, in patients with moderately to severely active ulcerative colitis from the phase 3 True North (TN) and open-label extension (OLE).

METHODS

All patients who received ozanimod in TN (n = 796) and all eligible TN patients who entered the OLE (n = 823) were included. Cardiovascular-related adverse events were evaluated in patients with up to 146 weeks of ozanimod exposure (2219 patient-years), which included 52 weeks during TN.

RESULTS

On TN day 1, first-dose ozanimod resulted in a 0.2 beats per minute mean decrease in heart rate from pretreatment to hour 6; 2 patients experienced bradycardia, which resolved without treatment modification. Mean systolic and diastolic blood pressure increases of 5.1 and 2.2 mm Hg, respectively, were observed at TN week 52. No second-degree Mobitz type II atrioventricular block events were reported; 1 third-degree atrioventricular block unrelated to ozanimod occurred in the OLE. Cardiac and vascular treatment-emergent adverse events were infrequent (3.8% [31 of 823] and 8.5% [70 of 823]); no ozanimod-related cardiovascular deaths occurred. The incidences of deep-vein thrombosis (0.2%; 2 of 823), pulmonary embolism (0.2%; 2 of 823), and ischemic stroke (0.4%; 3 of 823) in the OLE were low.

CONCLUSIONS

No new cardiovascular safety signals were identified, consistent with findings from previous ozanimod studies. There were few major adverse cardiovascular events or thromboembolic events, which were unrelated or unlikely related to ozanimod. Ozanimod has a well-tolerated cardiovascular safety profile when prescribed in accordance with the label.

Clinician's Guide to Using Ozanimod for the Treatment of Ulcerative Colitis

The emergence of advanced therapies [eg, biologics, Janus kinase inhibitors] over the past few decades has revolutionised the treatment of ulcerative colitis. However, the limitations of these therapies leave an unmet need for safer and more effective or convenient treatment options. There is growing interest in the development of novel oral small molecule therapies for the treatment of ulcerative colitis. Ozanimod is an oral small molecule therapy that is approved in the USA, the European Union, and other countries as the first sphingosine 1-phosphate receptor modulator for the treatment of moderately to severely active ulcerative colitis in adults. This review provides guidance for ozanimod use for the treatment of ulcerative colitis, based on the prescribing information, clinical trial and real-world data, and the authors' clinical experiences. This guidance outlines patient characteristics to consider when deciding if ozanimod treatment is suitable and describes how to educate patients on risks and best practices. It also details the nature and frequency of monitoring during treatment, which should be adapted to the individual patient based on pre-existing risk factors and events that possibly occur during treatment. This review also provides insights into the patient characteristics and clinical scenarios best suited for ozanimod treatment, based on its efficacy, safety profile, and risks compared with other therapies.

PURPOSE OF REVIEW

Ulcerative colitis (UC) is a chronic disease with an increasing incidence. Recent guidelines emphasize treating toward objective targets, requiring the use of effective, steroid-sparing therapies. This review summarizes the safety and efficacy data of available therapies as well comparative effectiveness studies in order to help the reader make rational treatment decisions.

RECENT FINDINGS

Following the approval of tumor necrosis factor alpha antagonists, we have seen recent regulatory approval of several additional biologic and small molecule agents from several therapeutic classes (integrin antagonists, interleukin 12/23 antagonists, Janus kinase inhibitors, and sphingosine-1-phosphate receptor antagonists) for UC. Randomized, controlled trials, real-world analyses, and network meta-analyses have investigated the comparative safety and efficacy of these therapies in order to help clinicians better position these therapies in clinical practice. Numerous agents are now approved for the treatment of UC. This evidence-based review will help the reader understand the important factors weighing into treatment decisions for patients with UC and enable patient education and discussion with a focus on a shared decision-making approach.
