Comparison of TAK-438 (Vonoprazan) to Lansoprazole in the Treatment of Duodenal Ulcer Participants With or Without Helicobacter Pylori Infection
- Conditions
- Duodenal Ulcer
- Interventions
- Drug: TAK-438 PlaceboDrug: Bismuth-Containing Quadruple Therapy
- Registration Number
- NCT03050359
- Lead Sponsor
- Takeda
- Brief Summary
The purpose of this study is to demonstrate the non-inferior efficacy of TAK-438 versus lansoprazole in the treatment of participants with duodenal ulcer.
- Detailed Description
The drug being tested in this study is called TAK-438. TAK-438 is being tested to treat people who have duodenal ulcers and also may or may not have Helicobacter pylori (HP) infection. This study will look at duodenal ulcer healing and also the elimination of HP in people who take TAK-438 versus lansoprazole. The study will enroll approximately 530 patients.
Participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which remained undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):
* TAK-438 20 mg
* Lansoprazole 30 mg
HP+ participants will be asked to take a TAK- 438 tablet and a lansoprazole capsule twice daily in conjunction with bismuth-containing quadruple therapy for 2 weeks, followed up by a TAK-438 tablet and a lansoprazole capsule once daily for up to 4 weeks. HP negative (HP-) participants will be asked to take a TAK-438 tablet and a lansoprazole capsule once daily for up to 6 weeks.
This multi-center trial will be conducted China, Korea and Taiwan. The overall time to participate in this study is up to 10 weeks. Participants will make multiple visits plus final visit at 2 weeks or 4 weeks after last dose of study drug for a follow-up assessment.

-
Has a known acquired immunodeficiency syndrome (AIDS) or hepatitis infection, including hepatitis virus carriers (hepatitis B surface-antigen [HBsAg] - or hepatitis C virus (HCV)-antibody-positive) (the participant may be included in the study if he/she is HCV-viral load-RNA-negative).
-
Laboratory tests performed prior to randomization revealed any of the following abnormalities in the participant:
- Creatinine levels: >2 mg/dL (>177 μmol/L).
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST), or total bilirubin levels: > upper limit of normal (ULN).
-
Has hypersensitivity to TAK-438, proton pump inhibitors (PPIs), bismuth, clarithromycin, or amoxicillin. Skin testing may be performed according to local standard practice (for HP+ participants only).

- Primary Outcome Measures
Name Time Method Percentage of Participants With Endoscopically Confirmed Healing of Duodenal Ulcers Week 4 or Week 6 Endoscopic healing was defined as the disappearance of all white coats associated with duodenal ulcers as confirmed endoscopically.
- Secondary Outcome Measures
Name Time Method Percentage of Participants With Posttreatment Resolution of Gastrointestinal Symptoms Associated With Duodenal Ulcer at Weeks 2 Through 6 Week 2 up to Week 6 The percentage of participants with resolution of various gastrointestinal symptoms are reported as categories. Gastrointestinal symptoms included epigastric pain (postprandial, fasting, nocturnal), abdominal bloating, nausea/vomiting, heartburn and lack of appetite. The severity of subjective symptoms of erosive esophagitis were recorded as: none = 0, mild = 1, moderate = 2 or severe = 3.
Percentage of Helicobacter Pylori Infected (HP+) Participants With Successful HP Eradication After 4 or 6 Weeks of Treatment 4 weeks post treatment (Up to 10 weeks) HP infection status was determined by \^13C Urea Breath Test (\^13C-UBT). The urea breath test is used to detect infection with HP, a bacteria associated with stomach ulcers, by testing individual breath samples in a central laboratory.
Percentage of Participants With Endoscopically Confirmed Healing of Duodenal Ulcer at Week 4 Week 4 Endoscopic healing is defined as the disappearance of all white coats associated with duodenal ulcers as confirmed endoscopically.
