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

Study Overview
=================
Brief Summary
-----------------
This is a Phase 1, randomized, double-blind, placebo-controlled, active-controlled, comparator controlled, multi-dose, parallel-group study divided into three treatment periods and a follow-up period with five treatment groups. This study will be conducted at 1 clinical research unit (CRU) in the United States (US). Period 1 will consist of daily escalating doses of tyramine administered until tyramine pressor response (defined as the tyramine dose required to increase systolic blood pressure by at least 30 mm Hg from the daily defined baseline in 3 consecutive measurements within 4 hours after tyramine dosing) is achieved or Day 7. Participants who achieve tyramine pressor response at tyramine doses >/= 200mg and </= 700mg are eligible for continuation into Period 2 and will be randomized accordingly. Depending on the group to which a participant is randomized, participants will receive rasagiline, phenelzine, ozanimod (therapeutic dose), ozanimod (supra-therapeutic dose), or placebo in Period 2. The duration of dosing depends on the group to which a participant is randomized. In Period 3, all participants will undergo a sham tyramine challenge and receive a single dose of tyramine placebo. Participants who do not achieve tyramine pressor response following the sham challenge will continue with the tyramine challenge (ie, tyramine pressor tests) for up to 12 additional days. Participants who receive at least one dose of study drug in Period 2 will participate in a follow-up phase during which 2 follow-up telephone calls will be performed, the last of which will occur approximately 80 to 100 days after the last dose of study drug.

Inclusion Criteria: Participants must satisfy the following criteria to be enrolled in the study: Be a male or non-pregnant, non-lactating female, 25 to 55 years of age, inclusive, at the time of signing the informed consent form. Must understand and voluntarily sign an informed consent form prior to any study-related assessments/procedures being conducted. Is willing and able to adhere to the study visit schedule and other protocol requirements. Female participant must meet at least 1 of the following criteria: Have a negative serum pregnancy test at Screening and Day -1 (females of child-bearing potential only). Be postmenopausal (defined as 2 years after the last period and follicle-stimulating hormone > 40 IU/L). Have received surgical sterilization (eg, bilateral tubal ligation, bilateral oophorectomy, hysterectomy) at least 6 months before Screening. Female of child-bearing potential: Must agree to practice a highly effective method of contraception at least 28 days prior to first dose of investigational product until completion of the 90-day safety follow-up period. Highly effective methods of contraception are those that alone or in combination result in a failure rate of a Pearl index of less than 1% per year when used consistently and correctly. Examples of acceptable methods of birth control in this study are the following: Combined hormonal (estrogen and progestogen containing) contraception, which may be oral, intravaginal, or transdermal Progestogen-only hormonal contraception associated with inhibition of ovulation, which may be oral, injectable, or implantable Placement of an intrauterine device or intrauterine hormone-releasing system Bilateral tubal occlusion Vasectomised partner Complete sexual abstinence Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together. Has a body weight of at least 110 pounds (50 kg); body mass index within the range of 18.0 to 30.0 kg/m2, inclusive.

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. a positive serum test for human immunodeficiency virus, hepatitis B virus, or hepatitis C virus . 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. consumed marijuana products within 3 months prior to the first dose of IP. a positive urine drug test including cotinine at Screening or Day -1. a positive alcohol breath or urine test at Screening or Day -1. 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. received a live or live attenuated vaccine within 4 weeks prior to the first dose of IP. 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. 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. used any MAO inhibitors within 90 days prior to the first dose of IP. a history of allergic reaction to tyramine, phenelzine, rasagiline, or S1P agonist. a history of adverse reactions to tyramine-containing foods. ingested alcohol within 7 days prior to the first dose of IP. fails or is unwilling to abstain from strenuous physical activities for at least 24 hours prior to the first dose of IP. poor peripheral venous access. donated greater than 400 mL of blood within 60 days prior to Day 1.
