A Pharmacokinetic Study of TAK-438 in Healthy Adult Chinese Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the pharmacokinetics (PK) of TAK-438 in healthy adult Chinese participants after both single and multiple dose administration.

Detailed Description
-----------------
The drug being tested in this study is called TAK-438. TAK-438 is being tested in healthy participants in order to evaluate the PK of single and multiple oral dose. The study will enroll approximately 36 healthy participants. Participants will be assigned to one of the three treatment groups: TAK-438 10 mg tablet once daily TAK-438 20 mg tablet once daily TAK-438 20 mg tablet twice daily All participants will be asked to take TAK-438 tablet at the same time on Day 1 and Days 3-9. This single-centre trial will be conducted in China. The overall time to participate in this study is 18 days. Participants will remain confined to the clinic from Day 1 up to Day 11 and will be followed-up by telephone or visit on Day 18.

Exclusion Criteria: Has uncontrolled, clinically significant cardiovascular disease or other abnormality, which may impact the ability of the participant to participate or potentially confound the study results. Is lactose intolerant or has a known hypersensitivity to any component of the formulation of TAK-438. Has poor peripheral venous access. Has donated or lost 400 milliliter (mL) or more of his or her blood volume (including plasmapheresis), or had a transfusion of any blood product within 90 days prior to Day 1; or participant has donated or lost more than 200 mL or more of his or her blood in the last 28 days. Has a history of symptomatic gastroesophageal reflux disease (GERD), Erosive Esophagitis, duodenal ulcer (DU), gastric ulcer (GU), dyspepsia, Barrett's Esophagus, or Zollinger-Ellison (ZE) syndrome or has current or recent (within 6 months) gastrointestinal disease that would be expected to influence the absorption of drugs.
