A Trial to Evaluate the Effect of the Proton Pump Inhibitor Esomeprazole on the Single-dose Pharmacokinetics (PK) of Oral TAK-906 in Healthy Adult Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effect of the proton pump inhibitor (PPI) esomeprazole on the single-dose PK of orally administered TAK-906.

Detailed Description
-----------------
The drug being tested in this study is called TAK-906. TAK-906 is being tested in healthy participants to evaluate the effect of a PPI esomeprazole on the PK of TAK-906. The study will enroll approximately 12 participants. Participants will be assigned to the following treatment sequence: • TAK-906 25 mg; Esomeprazole 40 mg + TAK-906 25 mg All participants will be given an oral dose of TAK-906 and Esomeprazole. This single center trial will be conducted in the United States. The overall duration to participate in this study is 52 days. Participants will make visit to the clinic during Period 1 and Period 2 in addition to approximately 10 to 14 days after receiving their last dose of TAK-906 for a follow up assessment.

* Drug: TAK-906
* Drug: Esomeprazole


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Continuous non-smoker who has not used nicotine containing products for at least 3 months prior to the first dosing and throughout the study, based on screening urine cotinine test. Has a body mass index (BMI) greater than or equal to (>=) 18 and less than or equal to (<=) 30 kilogram per square meter (kg/m^2) at Screening. Exclusion Criteria: History or presence of alcoholism or drug abuse within the past 2 years prior to the first dosing. QT interval corrected using Fridericia's formula (QTcF) interval is greater than (>) 450 millisecond (msec) or ECG findings are deemed abnormal with clinical significance by the Investigator or designee at screening. Donation of blood or significant blood loss (example, approximately 500 milliliter [mL]) within 56 days prior to the first dosing. Plasma donation within 7 days prior to the first dosing. Participation in another clinical study within 30 days or 5 half-lives prior to the first dosing. The 30 day window or 5 half-lives will be derived from the date of the last blood collection or dosing, whichever is later, in the previous study to Day 1 of Study Period 1 of the current study.

| AUClast: Area Under the Plasma Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration for TAK-906 |  | TAK-906 25 mg: Day 1 pre-dose and at multiple time points (up to 48 hours) post-TAK-906 dose; Esomeprazole 40 mg and TAK-906 25 mg: Day 4 pre-dose and at multiple time points (up to 48 hours) post- TAK-906 dose | 
| AUC∞: Area Under the Plasma Concentration-time Curve From Time 0 to Infinity for TAK-906 |  | TAK-906 25 mg: Day 1 pre-dose and at multiple time points (up to 48 hours) post-TAK-906 dose; Esomeprazole 40 mg and TAK-906 25 mg: Day 4 pre-dose and at multiple time points (up to 48 hours) post- TAK-906 dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Who Experienced at Least One Treatment Emergent Adverse Event (TEAE), Serious Adverse Event (SAE), and Grade 3 or Higher TEAEs | A severity grade is defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0. Grade 1 scales as Mild (asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated); Grade 2 scales as Moderate (minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL); Grade 3 scales as severe(severe or medically significant but not immediately life threatening hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL); Grade 4 scales as life-threatening consequences, urgent intervention indicated, and Grade 5 scales as death related to AE. | Baseline up to 14 days after last dose of TAK-906 in Study Period 2 (Day 23) |
