Ozanimod, sold under the brand name Zeposia, is a medication used to treat multiple sclerosis (MS) and ulcerative colitis (UC).[1][2] For MS this includes clinically isolated syndrome, relapsing-remitting, and active secondary progressive disease.[2] In UC it is used in those with moderate to severe disease.[2] It is taken by mouth.[2]
Common side effects include upper respiratory infection, liver inflammation, low blood pressure with standing, urinary tract infection, and back pain.[2] Other side effects may include heart arrhythmias, high blood pressure, and macular edema.[2] Use during or in the 3 months before pregnancy may harm the baby.[2] It is a sphingosine-1-phosphate (S1P) receptor agonist, which results in stopping lymphocytes from going to the brain and spinal cord.[1][2]
Ozanimod was approved for medical use in the United States, Europe, and Australia in 2020.[1][2][5] In the United Kingdom 4 weeks of medication costs the NHS about £1,400 as of 2021.[6] IN the United States this amount costs about 7,200 USD.[7]
In the United States, ozanimod is used to treat adults with relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease; and with moderately to severely active ulcerative colitis (UC).[4]
In the European Union and in Australia, ozanimod is indicated for the treatment of adults with relapsing remitting multiple sclerosis (RRMS).[5]
It is typically taken at a dose of 0.92 mg per day.[2] It; however, is started at 0.23 mg per day for 4 days, than 0.46 mg per day for 3 days, followed by the typical dose.[1]
Ozanimod is an agonist of the S1P1 and S1P5 receptors.[8] It demonstrates this effect in a dose-dependent manner, with 10-fold potency to three comparators.[8] This is an improvement of selectivity over its predecessor, fingolimod, which is non-specific to all 5 isotypes.[8] The agonism of S1P directly causes its internalization and degradation through the ubiquitin-proteosome pathway.[9] The loss of S1P leads to a decrease in the total lymphocyte count in circulation, specifically CD4+ CCR7+ and CD8+ CCR7+ T cells.[8][10]
Ozanimod has a high oral bioavailability, a circulating half-life of about 19 hours, and reaches highest blood plasma concentrations after about 6 hours.[8][10] Ozanimod is dehydrogenated by two CYP enzymes into two active metabolites, all with similar pharmacokinetics.[10] The decrease in lymphocyte count lasts for approximately 14 days after treatment discontinuation.[10] Unlike fingolimod, it does not require phosphorylation for activation, nor does it demonstrate cardiac abnormalities or hepatotoxicity.[8]
Ozanimod was discovered by The Scripps Research Institute and licensed to the biotech company Receptos Inc. which was acquired by Celgene Corp and then acquired by Bristol Myers Squibb.[11][12][13]
The US Food and Drug Administration (FDA) approved ozanimod based on evidence from two clinical trials (Trial 1/NCT02294058 and Trial 2/ NCT02047734) of 1767 subjects with relapsing forms of multiple sclerosis.[14] The trials were conducted at 173 centers in the United States, Belarus, Poland, Russia and Ukraine.[14] Subjects received ozanimod or comparator (interferon β1a, a product approved for the treatment of relapsing forms of multiple sclerosis) for up to one year (in Trial 1) or up to two years (in Trial 2).[14] Neither the subjects nor the health care providers knew which treatment was being given until the trials were completed.[14] The benefit of ozanimod was evaluated based on the percentage of subjects who experienced reduction in disease relapse in comparison to subjects treated with interferon β1a.[14]
In May 2021, the FDA approved ozanimod for an additional indcation for the treatment of moderately to severely active ulcerative colitis.[15]
After going public in May 2013, Receptos, Inc. stock surged with the clinical data ozanimod displayed as a S1P immunomodulating drug.[16][17] In August 2015, Receptos was acquired by Celgene for $7.2 billion through a combination of cash in hand and new debt, leading to a 22% increase in their stock value.[12][18] Receptos, Inc. (Celgene) patented the synthesis of ozanimod in July 2016.[19] With the expansion of Celgene's inflammation and immunology profile, the company had been expecting to generate $4 to $6 billion in annual sales from ozanimod; however, the FDA rejected its application for the drug's approval in February 2018.[17][20][21] Celgene refiled in March 2019.[citation needed] As the new owner, Bristol Myers Squibb received FDA approval on March 26, 2020, for ozanimod (Zeposia) oral capsules to treat adults with relapsing forms of multiple sclerosis (MS), including relapsing-remitting MS (RRMS), active secondary progressive MS (SPMS), and clinically isolated syndrome (CIS).[22] Ozanimod was approved for medical use in the European Union in May 2020,[1] and in Australia in July 2020.[3]
Ozanimod is in development for additional immune-inflammatory indications, including ulcerative colitis and Crohn's disease.[22][8][15]
Touchstone is a double-blind, placebo controlled phase II clinical for the treatment of ulcerative colitis.[23][24] 197 patients, ages 18–75, with moderate to severe UC (Mayo Score 6-10) were recruited and assigned either placebo, 0.5 mg or 1 mg of oral ozanimod followed by 1 week of dose escalation. The 1 mg dose showed a slight increase in rate of clinical remission of UC and total lymphocyte decrease as compared to the placebo, with the most common adverse effects being headaches and anemia.[23] The authors noted that limitations on this study included a brief duration and small sample size, meaning they could not assess safety nor efficacy.[23]
Radiance is a double-blind, placebo controlled phase combined II/III clinical trial for the treatment of relapsing multiple sclerosis.[25][26] For the phase II trial, 258 patients, ages 18–55 with RMS (Mean Expanded Disability Status Scale of 2.9) were assigned either placebo, 0.5 mg or 1 mg of oral ozanimod followed by 1 week of dose escalation.[25] Ozanimod significantly reduced MRI lesion activity in participants with relapsing multiple sclerosis over a period of 24 weeks.[25] Both doses of ozanimod reached anticipated range of 60-70% decreased lymphocyte count, and were well tolerated, with a safety profile consistent with a previous phase 1 study in healthy volunteers.[25][27] The most common adverse effects as compared to the placebo were: nasopharyngitis, headache, and urinary-tract infections, with no serious infectious or cardiac adverse effects.[25] With these results, both doses of ozanimod were taken forward into the 2-year long phase III trial and is completed but unpublished as of November 2016.[25][26]
Sunbeam is the second RMS phase III clinical trial to establish the dose with optimum safety-benefit relationship, with an estimated size of 1200 patients.[25][28]It began in November 2014, and has an estimated completion date of February 2017.[28][needs update]
