September 1, 2020 updated by: Daewoong Pharmaceutical Co. LTD.

A Multi-center, Double-Blind, Randomized, Active-controlled, Parallel-group, Phase III Clinical Trial to Evaluate the Efficacy and Safety of DWP14012 as Maintenance Therapy in Patients With Healed Erosive Esophagitis

This study aims to demonstrate the noninferiority of DWP14012 to Lansoprazole 15 mg in the maintenance effect of treatment and confirm the safety of DWP14012 in patients with healed erosive esophagitis confirmed on EGD after medication treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Proportion (%) of subjects with remission maintained on esophagogastroduodenoscopy by Week 24
Time Frame: at 24 week
at 24 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Proportion (%) of subjects with remission maintained on esophagogastroduodenoscopy by Week 12
Time Frame: at 12 week
at 12 week

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
GERD-Health related quality life(HRQL)
Time Frame: at Weeks 4, 12, and 24
Changes from baseline in the total score of GERD-HRQL at Weeks 4, 12, and 24(The total score could range from 0 to 50 and lower score was evaluated as higher quality of life)
at Weeks 4, 12, and 24
Assessment on symptoms
Time Frame: Weeks 4, 12, and 24
Proportions of subjects without the major symptoms (heartburn and/or acid regurgitation) at Weeks 4, 12, and 24
