Clinical Trial Summary

The purpose of this study is to demonstrate the non-inferior efficacy of TAK-438 versus lansoprazole in the treatment of participants with gastric ulcer.

Description:

The drug being tested in this study is called TAK-438. TAK-438 is being tested to treat people who have stomach ulcers and also may or may not have Helicobacter pylori (HP) infection. This study will look at stomach ulcer healing and also the elimination of HP in people who take TAK-438 versus lansoprazole. The study will enroll approximately 830 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participants and study doctor during the study (unless there is an urgent medical need): - TAK-438 20 mg - Lansoprazole 30 mg Study treatment will depend upon the Helicobacter pylori infection status of the participant, and include bismuth-containing quadruple therapy for the first 2 weeks in H pylori infected (HP+) participants. HP+ participants will be asked to take a TAK- 438 tablet or a lansoprazole capsule twice daily in conjunction with bismuth-containing quadruple therapy for 2 weeks, followed up by a TAK-438 tablet or a lansoprazole capsule once daily for up to 6 weeks. HP- participants will be asked to take a TAK-438 tablet or a lansoprazole capsule once daily for up to 8 weeks. This multi-center trial will be conducted in China, Korea, Taiwan, and Philippines. The overall time to participate in this study is up to 12 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.

16. Laboratory tests performed prior to randomization revealed any of the following

abnormalities in the participant:

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Endoscopically Confirmed Healing of Gastric Ulcers (GUs) at Weeks 4 or 8	Endoscopic healing was defined as the disappearance of all white coats associated with GUs confirmed endoscopically.	Week 4 or 8
Secondary	Percentage of Helicobacter Pylori Infected (HP+) Participants With Successful HP Eradication After 4 or 8 Weeks of Treatment	HP infection status was determined by 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. The data is provided only for HP+ participants. The participant could take 4 or 8 weeks of treatment for GU healing, then additional 4 weeks later, to have the urea breath test (UBT) test to detect HP.	4 weeks post treatment (up to approximately 12 weeks)
Secondary	Percentage of Participants With Endoscopically Confirmed Healing of GU at Week 4	Endoscopic healing was defined as the disappearance of all white coats associated with GUs confirmed endoscopically.	Week 4
Secondary	Percentage of Participants With Post-treatment Resolution of Gastrointestinal Symptoms Associated With GU	The gastrointestinal symptoms included epigastric pain [postprandial, fasting, nocturnal], abdominal bloating, nausea/vomiting, heartburn, lack of appetite. The severity of gastrointestinal symptoms associated with GU were recorded as: none = 0, mild = 1, moderate = 2 or severe = 3. The data is reported in categories for percentage of participants with resolution of gastrointestinal symptoms associated with GU.	Week 2 up to Week 8
