The purpose of the study is to evaluate the effects of a high fat meal on the pharmacokinetics of a single dose of 30 mg apremilast in healthy adults.

Participants will be randomized to receive a single dose of 30 mg apremilast during each of the 2 periods; once under fasting conditions and once after a high fat meal. Participants will be randomly assigned to receive apremilast either fasted first, then fed, or fed first then fasted. Participants will check into the study center on Day -1 of each period, will be dosed on Day 1, and discharged from the study center on Day 3 after all scheduled pharmacokinetic blood draws and safety evaluations. After a washout of 5 to 10 days, participants will return for period 2 during which they will receive apremilast according to their assigned sequence.

3. Exposure to an investigational drug (new chemical entity) within 30 days prior to the first dose administration or 5 half-lives of that investigational drug, if known (whichever is longer).
4. Subjects with known serum hepatitis, is a known carrier of hepatitis B surface antigen, hepatitis C antibody, or human immunodeficiency virus antibody.
5. Subjects who have used prescription systemic or topical medications within 30 days of dosing, unless it is being used to treat a stable, chronic medical condition. This includes medication that is an inhibitor or inducer of P-glycoprotein transporter and CYP-3A4/5 used within 14 days of dosing.

De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request

Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.

From first dose of study drug in Period 1 up to 5 to 10 days after dosing in Period 2, approximately 20 days.

Adverse events are reported for all participants who received at least 1 dose of study drug.
