NCT02388737

Brief Summary

This is a comparative study of vonoprazan (TAK-438) (10 mg or 20 mg) in participants in whom endoscopic healing of erosive esophagitis has been confirmed with vonoprazan or adequate treatment with a proton pump inhibitor (PPI), to demonstrate the non-inferiority of vonoprazan to lansoprazole in their maintenance treatment (6 months or 24 weeks) as well as to determine the clinically recommended dose for vonoprazan for maintenance therapy in erosive esophagitis.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Recurrence of Erosive Esophagitis as Confirmed on Endoscopy After the 24-week Maintenance Phase

    Erosive esophagitis recurrence is defined as participants endoscopically confirmed to have erosive esophagitis (Los Angeles \[LA\] classification grades A to D) during the Maintenance Phase (24 weeks). Grade A: \>/=1 mucosal breaks \</=5 mm, none of which extends between the tops of the mucosal folds; Grade B: \>/=1 mucosal breaks \>5 mm, none of which extends between the tops of two mucosal folds; Grade C: mucosal breaks that extend between the tops of two or more mucosal folds, but which involve \<75% of esophageal circumference; Grade D: mucosal breaks which involve \>/=75% of esophageal circumference.

    24 weeks

Secondary Outcomes (8)

  • Percentage of Participants With Recurrence of Erosive Esophagitis After 12 Weeks of Treatment in the Maintenance Phase

    12 weeks

  • Number of Participants With Adverse Events (AEs)

    From Day 1 to 14 days after the last dose of study medication (up to 26 weeks)

  • Number of Participants With Abnormal Clinical Laboratory Findings

    From Day 1 to 14 days after the last dose of study medication (up to 26 weeks)

  • Number of Participants With Abnormal Electrocardiogram (ECG) Findings

    From Day 1 to 14 days after the last dose of study medication (up to 26 weeks)

IPD Sharing
Will share

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.
