Drug-drug Interaction Study of Ozanimod With Inhibitor or Inducer of CYP2C8 and/or CYP3A

Completed · Phase 1

Conditions studied: Healthy Volunteer

In brief

The purpose of this study is to evaluate the effect of the following index inhibitors or inducers of CYP2C8 and/or CYP3A on the single-dose pharmacokinetics (PK) of ozanimod and its major active metabolite, CC112273, in healthy adult subjects: gemfibrozil (strong inhibitor of CYP2C8), rifampin (moderate inducer of CYP2C8 and strong inducer of CYP3A), and itraconazole (strong inhibitor of CYP3A). Study Design This is a Phase 1, randomized, parallel-group, open-label study with two parts, 1 and 2. Forty subjects will be enrolled in Part 1 and will be randomized into 1 of the 2 treatment groups, with 20 subjects in each treatment group. Sixty subjects will be enrolled in Part 2 and will be randomized into 1 of the 3 treatment groups, with 20 subjects in each treatment group. . Study parts and treatment groups are as follow: Part 1: * Treatment Group A (reference): A single dose of ozanimod. * Treatment Group B (test): Gemfibrozil 600 mg twice daily (BID) on Days 1 through 17. On Day 4, a single dose of ozanimod will be coadministered with the morning dose of gemfibrozil. Part 2: * Treatment Group C (reference): A single dose of ozanimod. * Treatment Group D (test): Itraconazole 200 mg once daily (QD) on Days 1 through 17. On Day 4, a single dose of ozanimod will be coadministered with itraconazole. * Treatment Group E (test): Rifampin 600 mg QD on Days 1 through 21. On Day 8, a single dose of ozanimod will be coadministered with rifampin. Study Population Subjects will be healthy men and non-pregnant, non-lactating women, ages 18 to 55 years, inclusive, with a body weight of at least 110 pounds (50 kg); body mass index (BMI) within the range of 18.0 to 30.0 kg/m2, inclusive. Length of Study The study duration ranges from 43 days to 50 days.

Who can join

Age: 18 and older, up to 55. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Subject is a man or non-pregnant, non-lactating woman, ages 18 to 55 years, inclusive, at the time of signing of the informed consent form (ICF).
• Female subjects must meet at least 1 of the following criteria:
• Negative serum pregnancy test at Screening and Day -1 (women of child-bearing potential [WOCBP] only).
• Postmenopausal (defined as 2 years after the last period and follicle-stimulating hormone [FSH] > 40 IU/L).
• Received surgical sterilization (eg, bilateral tubal ligation, bilateral oophorectomy, hysterectomy) at least 6 months before Screening with medical records.
• Females of child-bearing potential:
• Must agree to practice a highly effective method of contraception throughout the study until completion of the 75-day Safety Follow-up. 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.
• Acceptable methods of birth control in this study are the following:
• Combined hormonal (oestrogen 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, implantable
• Placement of an intrauterine device or intrauterine hormone-releasing system
• Bilateral tubal occlusion
• Vasectomized partner
• Sexual abstinence
• Male subjects:
• Must agree to use a latex condom with spermicide during sexual contact with WOCBP while participating in the study and until completion of the 75-day Safety Follow-up.
• All subjects:
• Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhea method are not acceptable methods of contraception. Female condom and male condom should not be used together.
• Male subjects must agree to refrain from donating sperm throughout the study and until completion of the 75-day Safety Follow-up.
• Subject has a body weight of at least 110 pounds (50 kg); body mass index (BMI) within the range of 18.0 to 30.0 kg/m2, inclusive (Screening and Day -1).
• Subject is in good health, as determined by no clinically significant findings from medical or surgical history, 12-lead ECG, physical examination, clinical laboratory tests, and vital signs.
• Subject must be able to comprehend and provide written informed consent, and must be able to comply with the requirements of the study, including the study visit schedule and other protocol requirements.

You may not qualify if…

• Subject with a seated pulse rate outside 55 to 90 bpm at Screening or Day -1.
• Subject has a presence or history of any abnormality or illness that, in the opinion of the investigator, may affect absorption, distribution, metabolism, or elimination of the Investigational product (IP) or would limit the subject's ability to participate in and complete this clinical study.
• Subject has a history of alcoholism, drug abuse, or addiction within 24 months prior to Screening.
• Subject has a positive serum test for human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV).
