Brief summary:
The purpose of this study is to evaluate the oral bioavailability of two new tablet formulations of TAK-385 (T4 Formulation B and T4 Formulation C) under fasted and fed conditions, relative the T2 Formulation tablet; and to estimate the effect of food on the pharmacokinetics (PK) of a single oral dose of the T4 Formulation B tablet and the T4 Formulation C tablet.

Detailed description:
The drug being tested in this study is called TAK-385. In this study, two new formulations of TAK-385 are being evaluated under fasted and fed conditions, relative to a previous formulation of TAK-385, to assess its bioavailability and how it is processed by the body. This study will look at lab results of people who take TAK-385.

The study will enroll approximately 54 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups (Arms). Participants in Arm 1 will receive TAK-385 T2 Formulation 120 mg tablet (80mg + 40mg tablets) under fasted conditions, TAK-385 T4 Formulation B 120 mg tablet under fasted conditions, and TAK-385 T4 Formulation B 120 mg tablet under fed conditions. Participants in Arm 2 will receive TAK-385 T2 Formulation 120 mg tablet (80mg + 40mg tablets) under fasted conditions, TAK-385 T4 Formulation C 120 mg tablet under fasted conditions, and TAK-385 T4 Formulation C 120 mg tablet under fed conditions. Participants in each arm will be randomized to receive study drug in one of 6 treatment sequences. Study medication will be administered as a single dose on Days 1, 11 and 21. There will be a 10-day washout period between each dose.

This single-centre trial will be conducted in the United States. The overall time to participate in this study is 51 days. Participants will make 10 visits to the clinic, including three 4-day periods of confinement to the clinic, and will be contacted by telephone 30 days after last dose of study drug for a follow-up assessment.

Arms:
arm 1: T2 Formulation Regimen A (T2-A) TAK-385, 120 mg tablet (80 mg + 40 mg tablets), orally, under fasted conditions, T4 Formulation B Regimen B (T4B-B) TAK-385, 120 mg tablet, orally, under fasted conditions, and T4 Formulation B Regimen C (T4B-C) TAK-385, 120 mg tablet, orally, under fed conditions. There were 6 randomized sequences. Study medication was administered as a single dose on Days 1, 11 and 21. There was a 10-day washout period between each dose. arm 2: T2 Formulation Regimen A (T2-A) TAK-385, 120 mg tablet (80 mg + 40 mg tablets), orally, under fasted conditions, T4 Formulation C Regimen D (T4C-D) TAK-385, 120 mg tablet, orally, under fasted conditions, and T4 Formulation C Regimen E (T4C-E) TAK-385, 120 mg tablet, orally, under fed conditions. There were 6 randomized sequences. Study medication was administered as a single dose on Days 1, 11 and 21. There was 10-day washout period between each dose.
