Clinical Trial Summary

To evaluate the safety, tolerability, and pharmacokinetics (PK) of quadruple therapy with bismuth, clarithromycin, amoxicillin, and TAK-438 versus quadruple therapy with bismuth, clarithromycin, amoxicillin, and lansoprazole.

Description:

This is a phase 1, double-blind, parallel group study in participants with Helicobacter pylori (HP positive) who are, additionally, cytochrome P-450 (CYP)2C19 extensive metabolizers (EM) to evaluate the safety, tolerability and pharmacokinetics (PK) of a quadruple therapy with bismuth, clarithromycin, amoxicillin, and TAK-438 versus quadruple therapy with bismuth, clarithromycin, amoxicillin, and lansoprazole. The study will enroll 30 participants.

The treatment phase consists of quadruple therapy twice daily (BID) with tripotassium bismuth dicitrate (600 mg), clarithromycin (500 mg), amoxicillin (1000 mg), and TAK-438 (20 mg) (Group B) or quadruple therapy BID with tripotassium bismuth dicitrate (600 mg), clarithromycin (500 mg), amoxicillin (1000 mg),and lansoprazole (30 mg) (Group A) from Days 1 to 14. Participants will be discharged on Day 15 after final PK blood samples are collected and all procedures performed.

This single-center will be conducted in Korea. Participants will remain confined to the study site from check-in (Day -1) through Day 15 and will followed up through call on Day 17 and return on Day 42 for a follow-up assessment.

3. Has history of gastroesophageal reflux disease (GERD), symptomatic GERD, erosive esophagitis, duodenal ulcer, gastric ulcer, Barrett's esophagus, or Zollinger-Ellison syndrome.

4. Has undergone therapeutic upper gastrointestinal endoscopic therapy (example, endoscopic hemostasis or excision including biopsy) within 30 days prior to Screening.

5. Has undergone major surgical procedures within the past 1 month or are scheduled to undergo surgical procedures that may affect gastric acid secretion (example, abdominal surgery, vagotomy, or craniotomy).

6. Has a history of cancer, except basal cell carcinoma or Stage 1 squamous cell carcinoma of the skin that has been in remission for at least 5 years prior to Day 1.

7. Has a positive test result for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody, human immunodeficiency virus (HIV) antibody/antigen at Screening.

8. Has used nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patch or nicotine gum) within 6 weeks prior to Check-in. Cotinine test is positive at Screening or Check-in.

9. Has poor peripheral venous access. Has donated or lost 450 milliliter (mL) or more of his blood volume (including plasmapheresis), or had a transfusion of any blood product within 90 days prior to Day 1.

10. Has abnormal Screening or Check-in laboratory values that suggest a clinically significant underlying disease or subject with the following laboratory abnormalities: alanine aminotransferase (ALT), aspartate aminotransferase (AST) or total bilirubin > the upper limit of normal (ULN).

11. Has reduced renal function assessed by having an estimated glomerular filtration rate <90 milliliter per min per 1.73 square meter (mL/min/1.73 m^2) (as estimated by Chronic Kidney Disease-Epidemology Collaboration) at Screening or Check-in.
