Abstract
OBJECTIVE To review the pharmacologic and clinical profile of etrasimod in the treatment of ulcerative colitis (UC). DATA SOURCES A PubMed search was conducted from inception to November 2023 using the keywords etrasimod, ulcerative colitis, and sphingosine-1-phosphate receptor modulator. Information was also obtained from published abstracts and package insert. STUDY SELECTION AND DATA EXTRACTION Phase 2 and 3 studies plus relevant literature on etrasimod pharmacologic and clinical profile were reviewed. DATA SYNTHESIS Per ELEVATE, 2 phase 3 studies, a higher proportion of patients with moderately to severely active UC achieved clinical remission in the induction and maintenance phase with etrasimod compared with placebo. In addition, a higher proportion of patients achieved secondary endpoints of clinical response, endoscopic improvement-histologic remission, corticosteroid-free remission, and endoscopic improvement with etrasimod vs placebo. Common adverse events include anemia and headache. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON WITH EXISTING DRUGS Etrasimod is now the second orally administered sphingosine-1-phosphate modulator approved for UC, providing patients with additional treatment options. Efficacy rates of this treatment are in line with other UC medication options. Similar to other sphingosine-1-phosphate receptor modulators, various assessments are required at baseline and during treatment to ensure safe and appropriate use. CONCLUSION Etrasimod is another possibility in the armamentarium of UC treatment, providing patients with more oral medication options. Prior to treatment initiation, several assessments relating to safety, drug interactions, and pharmacogenomics factors are advised.

Abstract
INTRODUCTION Ulcerative colitis is a chronic inflammatory bowel disease, affecting the colorectal mucosae, with a relapsing-remitting course, characterized by the trafficking and gathering of lymphocytes in the inflammatory intestinal mucosa. Sphingosine-1-phosphate (S1P) receptor modulators preventing lymphocytes egress from lymphoid tissues to the active inflammation site is an alternative therapeutic option in this condition. AREA COVERED We carried out a comprehensive review of the literature available on Medline, Scopus and Embase regarding the pharmacokinetics of S1P receptor modulators. For each compound, we reviewed the mechanism of action, pharmacokinetic data and efficacy and safety data from phase 3 studies and real-life studies when available. EXPERT OPINION S1P receptor modulators, including ozanimod and etrasimod (both currently on the market) as well as VTX002 (under development), are a new class of drugs for the treatment of moderate to severe ulcerative colitis, inducing and maintaining the remission. Due to its pharmacokinetic features, this class of drugs has certain advantages such as an oral administration, a short half-life, a high volume of distribution, and no immunogenicity. On the other hand, there are risks of cardiological and ophthalmological side-effects, as well as drug-drug interactions risk, that require special attention from the healthcare providers.

Abstract
Etrasimod, a novel selective sphingosine-1-phosphate receptor modulator, was recently approved by the U.S. Food and Drug Administration and the European Medicinal Agency for the treatment of moderately to severely active ulcerative colitis in adults. In this research, the forced degradation study as an integral part of drug product and packaging development, which generates data on degradation mechanisms, is published. The development and validation of the stability-indicating method using a superior high-performance liquid chromatography technique coupled with a diode array detector and tandem mass spectrometer was performed to support the forced degradation study and monitor the formation of degradation products. Etrasimod demonstrated good stability under elevated temperature and basic stress conditions, while acidic hydrolysis, oxidative, and photolytic degradation produced eight degradation products. The knowledge of degradation products will be useful in the long-term stability study for establishing the acceptance criteria of etrasimod as a drug substance and dosage form during quality control and stability assessment. The eco-friendliness of the developed forced degradation procedure was evaluated using various greenness appraisal tools. The green metric tools showed that the forced degradation procedure obeys eco-friendly conditions.

Abstract
BACKGROUND Ozanimod showed efficacy and safety in the phase 2 STEPSTONE study conducted in patients with moderately to severely active Crohn's disease. AIMS This analysis assessed the effects of ozanimod on circulating lymphocytes in Crohn's disease. METHODS Patients received ozanimod 0.92 mg for 12 weeks. Lymphocyte subtypes were evaluated using multicolor flow analysis on blood samples collected before treatment and on Week 12. Absolute lymphocyte count changes were analyzed by Wilcoxon signed rank tests. Disease activity changes and efficacy outcomes were evaluated at Week 12, and associations with lymphocyte subtype levels were assessed using Spearman's correlation and logistic regression. RESULTS Reductions in median total T, Th, and cytotoxic T cells occurred at Week 12 (45.4%-76.8%), with reductions in most subtypes of 47.5% to 91.3% (P < 0.001). CD8+ terminally differentiated effector memory cells were largely unaffected (median change, - 19%; P = 0.44). Reductions in median total B cells occurred at Week 12 (76.7%), with reductions in subtypes of 71.4% to 81.7% (P < 0.001). Natural killer and monocyte cell counts were unchanged. Greater baseline levels and changes in nonswitched memory B cells were significantly associated with clinical, endoscopic, and histologic efficacy (P < 0.05, all comparisons). CONCLUSIONS Ozanimod reduced circulating levels of all B-cell and most T-cell subsets but not monocytes or natural killer cells. Key subsets relevant to immune surveillance were not reduced, supporting the low risk of infection and malignancy with ozanimod in chronic inflammatory diseases. Levels of nonswitched memory B cells were associated with efficacy, providing a potential marker for ozanimod response. TRIAL REGISTRATION ClinicalTrials.gov: NCT02531113, EudraCT: 2015-002025-19.

Abstract
The recent approval of new medications with novel mechanisms of action and emergence of updated safety information for existing therapies has changed the treatment landscape of inflammatory bowel disease (IBD). These advances led to unique adverse effect profiles and identification of new safety signals, resulting in the evolution of the safety, monitoring, and positioning of IBD therapies. In this updated review, we (1) examine the existing and updated safety data of monoclonal antibodies and small molecules for IBD, with a focus on recently Food and Drug Administration (FDA)-approved therapies, and (2) propose risk stratification and assessment considerations prior to and during IBD treatment.

Abstract
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.

Abstract
PURPOSE OF REVIEW Treatment of Inflammatory Bowel Diseases (IBD) is challenging; thus, the need for newer therapeutic options with an oral route of administration has led to the development of novel small molecules drugs (SMDs). We aim to highlight the most common Adverse events (AEs) associated with SMDs and recommendations on monitoring for AEs before and during treatment. RECENT FINDINGS SMDs, such as Tofacitinib, a JAK inhibitor, have been associated with laboratory abnormalities, infections, and risk of thromboembolic events. Therefore, oral agents with greater selectivity in JAK inhibition, such as tofacitinib and upadacitinib, were later developed. Ozanimod and etrasimod, S1PR agonists, require closer safety profile monitoring by clinicians. Multiple therapies have been recently developed with variable efficacy. However, they have been associated with AEs, and some require close monitoring prior to and during therapy. Clinicians should highlight these adverse events to patients while reassuring the safety profile of these novel SMDs for IBD is favorable.

Abstract
Four sphingosine 1-phosphate (S1P) receptor modulators (fingolimod, ozanimod, ponesimod, and siponimod) are approved by the US Food and Drug Administration for the treatment of multiple sclerosis. This review summarizes efficacy and safety data on these S1P receptor modulators, with an emphasis on similarities and differences. Efficacy data from the pivotal clinical trials are generally similar for the four agents. However, because no head-to-head clinical studies were conducted, direct efficacy comparisons cannot be made. Based on the adverse event profile of S1P receptor modulators, continued and regular monitoring of patients during treatment will be instructive. Notably, the authors recommend paying attention to the cardiac monitoring guidelines for these drugs, and when indicated screening for macular edema and cutaneous malignancies before starting treatment. To obtain the best outcome, clinicians should choose the drug based on disease type, history, and concomitant medications for each patient. Real-world data should help to determine whether there are meaningful differences in efficacy or side effects between these agents.

Abstract
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.

Abstract
Sphingolipids are essential components of all eukaryotic membranes. The bioactive sphingolipid molecule, Sphingosine 1-Phosphate (S1P), regulates various important biological functions. This review aims to provide a comprehensive overview of the role of S1P signaling pathway in various immune cell functions under different pathophysiological conditions including bacterial and viral infections, autoimmune disorders, inflammation, and cancer. We covered the aspects of S1P pathways in NOD/TLR pathways, bacterial and viral infections, autoimmune disorders, and tumor immunology. This implies that targeting S1P signaling can be used as a strategy to block these pathologies. Our current understanding of targeting various components of S1P signaling for therapeutic purposes and the present status of S1P pathway inhibitors or modulators in disease conditions where the host immune system plays a pivotal role is the primary focus of this review.

Abstract
Ozanimod is approved in multiple countries for the treatment of adults with either relapsing multiple sclerosis or moderately to severely active ulcerative colitis. Ozanimod is metabolized in humans to form seven active plasma metabolites, including two major active metabolites CC112273 and CC1084037, and an inactive metabolite. Here, the binding and activity of ozanimod and its metabolites across human sphingosine 1-phosphate receptors were determined. Binding affinity was assessed in Chinese hamster ovary cell membranes expressing recombinant human sphingosine 1-phosphate receptors 1 and 5 via competitive radioligand binding using tritium-labeled ozanimod; selectivity via functional potency assessment was performed using [35S]-guanosine-5'-(γ-thio)-triphosphate binding assays. Receptor internalization was assessed in human embryonic kidney 293 cells overexpressing sphingosine 1-phosphate receptor 1-green fluorescent protein and Chinese hamster ovary cells overexpressing sphingosine 1-phosphate receptor 5-hemagglutinin via fluorescence activated cell sorting. Functional activity was assessed in primary cultures of human astrocytes via phosphorylation assays. Ozanimod and its functionally active metabolites bound to the same sites within sphingosine 1-phosphate receptors 1 and 5, with metabolites displaying the same selectivity profile as ozanimod. Agonism at sphingosine 1-phosphate receptor 1 induced receptor internalization, whereas sphingosine 1-phosphate receptor 5 did not. Ozanimod, CC112273, and CC1084037 elicited functional intracellular signaling in human astrocytes, pharmacologically characterized to be mediated by sphingosine 1-phosphate receptor 1. The active plasma metabolites of ozanimod bound to sphingosine 1-phosphate receptors 1 and 5 and displayed similar pharmacologic profiles as their parent compound, likely contributing to clinical efficacy in patients with relapsing multiple sclerosis or moderately to severely active ulcerative colitis.

[PMID: 36434688 PMCID: PMC9701001 DOI: 10.1186/s13020-022-00684-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 11/03/2022] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Pulsatilla decoction (Bai-Tou-Weng-Tang, BTWT) is a classic formula prescription of a traditional Chinese medicine that is used to treat ulcerative colitis (UC). However, its active components and underlying mechanism of action remain unclear. In the present study, we aimed to identify potential immunomodulators from BTWT that act at therapeutic targets for UC. METHODS The protective effects of BTWT granules were examined in mice with colitis induced by dextran sulfate sodium. The absorbed components of BTWT were identified using LC-MS, and selected protein targets of these components in UC were investigated using molecular docking. RESULTS Oral administration of BTWT granules significantly alleviated disease severity and colon shortening, and inhibited the inflammatory response in mice with chronic colitis. In these mice, 11 compounds from the BTWT granules were detected in the serum and/or colon. The molecular docking study demonstrated that compounds from Radix pulsatillae, such as anemoside A3, interacted with STAT3 and S1PR1; compounds from Rhizoma coptidis and/or Cortex phellodendri, such as palmatine, interacted with JAK3, PD-1, and PD-L1; and components of Cortex fraxini such as aesculin interacted with S1PR1, JAK3, STAT3 and PD-L1. Further in-vitro experiments showing that the compounds inhibited TNF-α and IL-6 production and STAT3 activation in RAW 264.7 cells suggested that these compounds have immunomodulatory activities. CONCLUSION We revealed for the first time that 11 absorbed ingredients from BTWT were immunomodulators against therapeutic targets for UC. These findings suggest that the identified compounds are the active components of BTWT, and the identified protein targets underlie the mechanism of action of BTWT against UC.

Ozanimod as a novel oral small molecule therapy for the treatment of Crohn's disease: The YELLOWSTONE clinical trial program. Contemp Clin Trials 2022; 122:106958. [PMID: 36208720 PMCID: PMC10008122 DOI: 10.1016/j.cct.2022.106958] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 09/29/2022] [Accepted: 10/01/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND Ozanimod, an oral sphingosine 1-phosphate receptor modulator currently approved for the treatment of moderately to severely active ulcerative colitis and relapsing multiple sclerosis, showed clinical, endoscopic, and histological benefit in the phase 2 STEPSTONE trial for Crohn's disease (CD). We aim to describe the trial design of the YELLOWSTONE phase 3 program evaluating the safety and efficacy of ozanimod in patients with moderately to severely active CD. METHODS The YELLOWSTONE program consists of phase 3, randomized, double-blind, placebo-controlled induction (NCT03440372 and NCT03440385) and maintenance (NCT03464097) trials and an open-label extension (OLE) study (NCT03467958). Patients with inadequate response or intolerance to ≥1 CD treatment are randomized to receive daily ozanimod 0.92 mg (equivalent to ozanimod HCl 1 mg) or placebo for 12 weeks during induction. Those who respond to ozanimod are rerandomized to continue ozanimod or placebo maintenance therapy for 52 weeks. Patients who do not meet criteria for maintenance, experience relapse during maintenance, or complete maintenance or ≥ 1 year of STEPSTONE are eligible for open-label treatment for up to 234 weeks. Efficacy endpoints include clinical, endoscopic, and histologic outcomes. RESULTS Expected 2023 (induction studies), 2024 (maintenance study), and 2026 (OLE). CONCLUSION YELLOWSTONE will provide pivotal phase 3 data on the safety and efficacy of ozanimod in patients with moderately to severely active CD using state-of-the-art methods, including centrally read endoscopic and histologic measurements, along with subjective assessments of symptom control based on the Crohn's Disease Activity Index. These studies could enable approval of ozanimod as a new CD therapy. CLINICAL TRIAL REGISTRATION NUMBERS NCT03440372, NCT03440385, NCT03464097, NCT03467958.

Abstract
Incidence of gastrointestinal (GI) cancers is increasing, and late-stage diagnosis makes these cancers difficult to treat. Chronic and low-grade inflammation are recognized risks for most GI cancers. The GI mucosal immune system maintains healthy homeostasis and signalling molecules made from saturated fats, bioactive sphingolipids, play essential roles in healthy GI immunity. Sphingosine-1-phosphate (S1P), a bioactive sphingolipid, is a key mediator in a balanced GI immune response. Disruption in the S1P pathway underlies systemic chronic metabolic inflammatory disorders, including diabetes and GI cancers, providing a strong rationale for using modulators of the S1P pathway to treat pathological inflammation. Here, we discuss the effects of bioactive sphingolipids in immune homeostasis with a focus on S1P in chronic low-grade inflammation associated with increased risk of GI carcinogenesis. Contemporary information on S1P signalling involvement in cancers of the digestive system, from top to bottom, is reviewed. Further, we discuss the use of novel S1P receptor modulators currently in clinical trials and their potential as first-line drugs in the clinic for chronic inflammatory diseases. Recently, ozanimod (ZeposiaTM) and etrasimod have been approved for clinical use to treat ulcerative colitis and eosinophilic oesophagitis, respectively, which may have longer term benefits in reducing risk of GI cancers.
