Brief summary:
This study will assess up to 12 different oral formulations of apremilast to determine how much apremilast is absorbed by the body compared to a reference formulation.

Detailed description:
This will be a single-center, open-label, crossover, single modified-release-dose study in adult males to evaluate the pharmacokinetics (PK) of prototype modified-release (MR) formulations compared to the reference immediate-release (IR) apremilast formulation. Within 4 separate groups, participants will be randomly assigned to a treatment sequence. A total of up to 12 test MR formulations may be evaluated.

Group 1: A 4-sequence, 4-period design to compare three modified-release prototypes with the reference immediate-release formulation. A total of 16 participants will be enrolled to obtain at least 12 participants who complete all 4 periods.

Group 2: A 4-sequence, 4-period design to compare three MR prototypes with the reference IR formulation. Sixteen participants will be enrolled to obtain at least 12 participants who complete all four periods.

Group 3: A six-sequence, three-period design to compare two MR prototypes with the reference IR formulation. Eighteen participants will be enrolled to obtain at least 12 participants who complete all three periods.

Group 4: A 10-sequence, 5-period design to compare four MR prototypes with the reference IR formulation. Thirty participants will be enrolled to obtain at least 20 participants who complete all five periods.

Arms: arm 1: Participants received the following 4 treatments, given in 4 possible sequences (ADBC, BACD, CBDA, and DCAB) with 7 to 10 days between each treatment:

A) Two oral doses of 30 mg apremilast immediate release tablets 12 hours apart (reference formulation) B) A single oral dose 75 mg apremilast tablet prototype MR 1 C) A single oral dose 75 mg apremilast tablet prototype MR 2 D) A single oral dose 75 mg apremilast capsule prototype MR 3 arm 2: Participants received the following 4 treatments, given in 4 possible sequences (AGEF, EAFG, FEGA, and GFAE) with 7 to 10 days between each treatment:

A) Two oral doses of 30 mg apremilast immediate release tablets 12 hours apart (reference formulation) E) A single oral dose 75 mg apremilast capsule prototype MR 4 F) A single oral dose 75 mg apremilast capsule prototype MR 5 G) A single oral dose 75 mg apremilast capsule prototype MR 6 arm 3: Participants received the following 3 treatments, given in 6 possible sequences (AIJ, IJA, JAI, AJI, IAJ, or JIA) with 7 to 10 days between each treatment:

A) Two oral doses of 30 mg apremilast immediate release tablets 12 hours apart (reference formulation) I) A single oral dose 80 mg apremilast capsule prototype MR 8 J) A single oral dose 80 mg apremilast capsule prototype MR 9 arm 4: Participants received the following 5 treatments, given in 10 possible sequences (ALOMN, LMANO, MNLOA, NOMAL, OANLM, NMOLA, ONAML, AOLNM, LAMON, or MLNAO) with 7 to 10 days between each treatment:

A) Two oral doses of 30 mg apremilast immediate release tablets 12 hours apart (reference formulation) L) A single oral dose 80 mg apremilast capsule prototype MR 11 M) A single oral dose 80 mg apremilast capsule prototype MR 12 N) A single oral dose 80 mg apremilast capsule prototype MR 13 O) A single oral dose 80 mg apremilast capsule prototype MR 14
