This is a single-center, randomized, double-blind, placebo-controlled clinical Study to evaluate the efficacy of DA-5204 and proton pump inhibitor combination therapy compared with proton pump inhibitor alone therapy in patients with gastroesophageal reflux Disease.

Опис

Gastroesophageal reflux disease is a condition in which reflux of stomach contents into the esophagus causes troublesome symptoms, such as heartburn and acid regurgitation.

Proton pump inhibitors, as acid suppressor, are the agents recommended as the first-line treatment for gastroesophageal reflux disease. However, approximately 20-30% of patients have insufficient effect on this therapy alone.

DA-5204 is a medicine based on Artemisia asiatica 95% ethanol extract. DA-5204 has been administered to treat gastritis and gastric ulcers with antioxidative and cytoprotective actions on gastric mucosal damage. Therefore, we expect DA-5204 to be effective in reflux esophagitis (esophageal mucosal injury).

Исход

Примарне мере исхода

1. Endoscopically effective improvement [4 weeks]

A percentage of subjects showed effective improvement of erosive esophagitis (esophageal mucosal injury) by the endoscopy. The definition of "effective improvement" is the subjects showed score changed from 3 to 0, from 2 to 0, or from 3 to 1. [score 0(LA grade N): normal mucosa, score 1(LA grade M): minimal changes to the mucosa such as erythema, blurring and/or whitish turbidity, score 2(LA grade A): non-confluent mucosal breaks <5 mm in length, score 3(LA grade B): non-confluent mucosal breaks ≥5 mm in length]

2. Endoscopically complete improvement [4 weeks]

A percentage of subjects showed complete improvement of erosive esophagitis (esophageal mucosal injury) by the endoscopy. The definition of "complete improvement" is the subjects showed score changed from 3 to 0 or from 2 to 0.

Секундарне мере исхода

1. Symptom improvement [4 weeks]

A percentage of subjects showed sufficient improvement of reflux symptom score from Gastroesophageal Reflux Disease Questionnaire (GerdQ). The definition of "sufficient improvement" is the subjects showed ≥50% reduction from the initial sum of scores for GerdQ.
