TAK-438 20 mg

Lansoprazole 30 mg

Arm Description

H. pylori negative (HP -) participants: TAK-438 20 mg, tablets, orally, once daily (QD) and lansoprazole placebo-matching capsules, orally, QD for up to 6 weeks. H. pylori positive (HP +) participants: TAK-438 20 mg, tablets, orally, twice daily (BID) and lansoprazole placebo-matching capsules, orally, BID for first 2 weeks along with Bismuth-Containing Quadruple Therapy followed byTAK-438 20 mg, tablets, orally, QD and lansoprazole placebo-matching capsules, orally, QD for up to 4 weeks.

H. pylori negative (HP -) participants: lansoprazole 30 mg, capsules, orally, QD and TAK-438 placebo-matching tablets, orally, QD for up to 6 weeks. HP + participants: lansoprazole 30 mg, capsules, orally, BID and TAK-438 placebo-matching tablets, orally, BID for first 2 weeks along with Bismuth-Containing Quadruple Therapy followed by lansoprazole 30 mg, capsules, orally, QD and TAK-438 placebo-matching tablets, orally, BID for up to 4 weeks.

Outcomes

Primary Outcome Measures

Percentage of Participants With Endoscopically Confirmed Healing of Duodenal Ulcers
Endoscopic healing was defined as the disappearance of all white coats associated with duodenal ulcers as confirmed endoscopically.

Secondary Outcome Measures

Percentage of Helicobacter Pylori Infected (HP+) Participants With Successful HP Eradication After 4 or 6 Weeks of Treatment
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
Endoscopic healing is defined as the disappearance of all white coats associated with duodenal ulcers as confirmed endoscopically.
Percentage of Participants With Posttreatment Resolution of Gastrointestinal Symptoms Associated With Duodenal Ulcer at Weeks 2 Through 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.

5. Study Description

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.

12. IPD Sharing Statement

Plan to Share IPD
Yes
IPD Sharing Plan Description
Takeda makes patient-level, de-identified data sets and associated documents available for all interventional studies after applicable marketing approvals and commercial availability have been received (or program is completely terminated), an opportunity for the primary publication of the research and final report development has been allowed, and other criteria have been met as set forth in Takeda's Data Sharing Policy (see www.TakedaClinicalTrials.com for details). To obtain access, researchers must submit a legitimate academic research proposal for adjudication by an independent review panel, who will review the scientific merit of the research and the requestor's qualifications and conflict of interest that can result in potential bias. Once approved, qualified researchers who sign a data sharing agreement are provided access to these data in a secure research environment.
