Study to Evaluate the Pressor Effect of Oral Tyramine During Ozanimod Treatment in Healthy Adult Participants

Exclusion Criteria

• •The presence of any of the following will exclude a participant from enrollment:
• •1. an unstable SBP (ie, SBP exceeds a maximum range of 15 mm Hg between the lowest and highest values in three consecutive measurements within 15 minutes during Screening).
• •2. the presence or history of any clinically relevant abnormality, condition, or disease (such as glaucoma, liver disease or abnormal liver function tests, cardiovascular or pulmonary diseases) that, in the opinion of the Investigator, may affect absorption, distribution, metabolism, or elimination of the IPs, that would prevent the participant from participating in the study, or which places the participant at unacceptable risk if he/she were to participate in the study.
• •3. any condition that confounds the ability to interpret data from the study.
• •4. history of bipolar, depression or suicidal ideation or behavior, or a history of psychiatric illnesses.
• •5. history of clinically significant or unstable vascular disease, a history of syncope associated with hypotension within the last 2 years, a history of orthostatic hypotension (ie, SBP decrease of \> 20 mm Hg between 2 and 5 minutes after standing compared with supine SBP), or a history of tachycardia or hypertension.
• •6. an estimated glomerular filtration rate (eGFR) \< 80 mL/min/1.73 m2 according to the 2009 chronic kidney disease (CKD) epidemiology collaboration (CKD EPI) equation: eGFR = 141 × min(Scr/κ, 1) × max(Scr/κ, 1)-1.209 × 0.993Age × 1.018 \[if female\] × 1.159 \[if African American\] where: Scr is serum creatinine in mg/dL, κ is 0.7 for females and 0.9 for males, α is -0.329 for females and -0.411 for males, min indicates the minimum of Scr/κ or 1, and max indicates the maximum of Scr/κ or 1.
• •7. a seated heart rate outside 55 to 95 beats per minute at Screening or Day -1.
• •8. a resting QTcF \> 450 msec (males) or \> 470 msec (females) or PR interval \> 210 msec at Screening or Day -1 or at additional risk for QT interval prolongation.
• •9. a history of diabetes mellitus type 1, or uncontrolled diabetes mellitus type 2 with hemoglobin A1c (HbA1c) \> 8%.
• •10. a history of uveitis (within the last year prior to Screening) or clinically confirmed diagnosis of macular edema.
• •11. a history of alcoholism, drug abuse, or addiction within 24 months prior to Screening.
• •12. a known active bacterial, viral, fungal (excluding fungal infection of nail beds, minor upper respiratory tract infections, and minor skin infections), mycobacterial infection (including tuberculosis or atypical mycobacterial disease) or any major episode of infection that required hospitalization or treatment with intravenous antibiotics within 30 days of Screening or oral antibiotics within 14 days of Screening.
• •* In the case of prior SARS-CoV-2 infection, symptoms must have completely resolved and based on Investigator assessment in consultation with the Medical Monitor, there are no sequelae that would place the participant at a higher risk of receiving investigational treatment.
• •13. a positive serum test for human immunodeficiency virus, hepatitis B virus, or hepatitis C virus .
• •14. used any tobacco- or nicotine-containing products (including but not limited to cigarettes, pipes, cigars, electronic cigarettes, chewing tobacco, nicotine patches, nicotine lozenges, or nicotine gum) within 3 months prior to the first dose of IP.
• •15. consumed marijuana products within 3 months prior to the first dose of IP.
• •16. a positive urine drug test including cotinine at Screening or Day -1.
• •17. a positive alcohol breath or urine test at Screening or Day -1.
• •18. received any investigational drug within 30 days or 5 times the elimination half-life (if known), whichever is longer, prior to the first dose of IP.
• •19. received a live or live attenuated vaccine within 4 weeks prior to the first dose of IP.
• •20. used any over-the-counter medication (excluding acetaminophen up to 1 g/day), dietary or herbal supplement (excluding vitamins/multi-vitamins), octopamine within 14 days prior to the first dose of IP. St. John's wort must be discontinued at least 28 days prior to the first dose of IP.
• •21. used any systemic prescription medication (excluding hormonal contraceptives) within 28 days or 5 times the elimination half-life, whichever is longer, prior to the first dose of IP.
• •22. used any MAO inhibitors within 90 days prior to the first dose of IP.
• •23. a history of allergic reaction to tyramine, phenelzine, rasagiline, or S1P agonist.
• •24. a history of adverse reactions to tyramine-containing foods.
• •25. ingested alcohol within 7 days prior to the first dose of IP.
• •26. fails or is unwilling to abstain from strenuous physical activities for at least 24 hours prior to the first dose of IP.
• •27. poor peripheral venous access.
• •28. donated greater than 400 mL of blood within 60 days prior to Day 1.
