Official title

A Phase 1, Randomized, Parallel-Group, Open-Label Study to Evaluate the Effect of the Modulators of the Cytochrome P450 (CYP) 2C8 and/or 3A on the Single-Dose Pharmacokinetics of Ozanimod and CC112273 in Healthy Adult Subjects

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
