Brief summary:
The purpose of this study is to evaluate the relative bioavailability of apremilast once-daily formulation relative to a twice daily formulation when administered as multiple doses (Part 1), and when administered as a single dose under fasting and fed conditions (Part 2). Information on safety and tolerability will also be obtained.

Detailed description:
Part 1: This is an open-label, randomized, two-period, two-sequence, crossover study in healthy subjects. The study will consist of a screening phase, a baseline phase, two treatment periods, and a follow-up phone call. Each period will be ten days in duration including 7 days of dosing and sample collection for up to 72 hours post Day 7 morning dose. There will be a washout between period 1 and period 2.

Part 2: This is an open-label, randomized, four-period, four-sequence crossover study to evaluate the PK and exposure of apremilast following single dose administration of different formulations of apremilast. Part 2 will consist of a screening phase, baseline, four treatment periods, and a follow-up phone call. Each period will be four days in duration for dosing (Day 1) and sample collection for up to 72 hours post Day 1.

Arms:
arm 1: Participants received apremilast 30 mg immediate release (IR) tablet twice a day (BID) for 7 days in treatment period 1 then apremilast 75 mg extended release (XL) formulation once a day (QD) for 7 days in treatment period 2. arm 2: Participants received apremilast 75 mg XL formulation once a day for 7 days in treatment period 1 then apremilast 30 mg IR tablet twice a day for 7 days in treatment period 2. arm 3: Participants received a single dose of apremilast in each of 4 treatment periods according to the following:

Treatment period 1: Apremilast 30 mg IR tablet under fasted conditions; Treatment period 2: Apremilast 75 mg XL formulation after a high-fat meal; Treatment period 3: Apremilast 75 mg XL formulation under fasted conditions; Treatment period 4: Apremilast 75 mg XL formulation after a standard meal. arm 4: Participants received a single dose of apremilast in each of 4 treatment periods according to the following:

Treatment period 1: Apremilast 75 mg XL formulation under fasted conditions; Treatment period 2: Apremilast 30 mg IR tablet under fasted conditions; Treatment period 3: Apremilast 75 mg XL formulation after a standard meal; Treatment period 4: Apremilast 75 mg XL formulation after a high-fat meal. arm 5: Participants received a single dose of apremilast in each of 4 treatment periods according to the following:

Treatment period 1: Apremilast 75 mg XL formulation after a standard meal; Treatment period 2: Apremilast 75 mg XL formulation under fasted conditions; Treatment period 3: Apremilast 75 mg XL formulation after a high-fat meal; Treatment period 4: Apremilast 30 mg IR tablet under fasted conditions. arm 6: Participants received a single dose of apremilast in each of 4 treatment periods according to the following:

Treatment period 1: Apremilast 75 mg XL formulation after a high-fat meal; Treatment period 2: Apremilast 75 mg XL formulation after a standard meal; Treatment period 3: Apremilast 30 mg IR tablet under fasted conditions; Treatment period 4: Apremilast 75 mg XL formulation under fasted conditions.
