About this trial
This Phase III clinical trial is designed to assess the efficacy and safety of Anaprazole 60 mg once daily (QD) administered over a period of up to 8 weeks, compared with Rabeprazole 20 mg QD, in patients with reflux esophagitis.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
The patients provided voluntary signed informed consent forms.
Aged ≥18 years and ≤75 years old.
Endoscopically diagnosed as reflux esophagitis (LA grade B-D) within 14 days before randomization.
Disqualifiers
Researchers believe that patients with uncontrolled primary diseases are not suitable for clinical trials, particularly those with a history of severe conditions affecting the cardiovascular, nervous, respiratory, hepatic, renal, or other systems.
Patients with concomitant diseases that may affect the esophagus or esophageal motility and, could potentially influence the efficacy evaluation.
Patients with a history of prior surgical procedures that could potentially impact esophageal function, or surgeries.
Patients confirmed to have active peptic ulcers or active upper/lower gastrointestinal bleeding within the last 30 days via esophagogastroduodenoscopy (EGD).

Treatments tested in this trial
Anaprazole + Rabeprazole placebo
DrugAnaprazole 3 tablets (20 mg/tablet) + Rabeprazole placebo 1 tablet (0.16 g/tablet), administered orally 30-60 minutes before breakfast once daily for up to 8 weeks. After 4 weeks of continuous treatment, if endoscopic evaluation confirms the cure of reflux esophagitis, treatment may be discontinued.
Rabeprazole + Anaprazole placebo
DrugRabeprazole 1 tablet (20 mg/tablet) + Anaprazole placebo 3 tablets (0.2 g/tablet), orally administered 30-60 minutes before breakfast once daily for up to 8 weeks. After 4 weeks of continuous treatment, if endoscopic evaluation confirms the cure of reflux esophagitis, treatment may be discontinued.

Trial outcomes
Primary outcomes
The endoscopic healing rate of reflux esophagitis
The endoscopic healing rate of reflux esophagitis is defined as the proportion of patients with reflux esophagitis who achieve complete mucosal healing. Complete healing is determined by the absence of mucosal breaks upon endoscopic evaluation post-treatment, and the lesion is classified as normal according to the LA classification.
Secondary outcomes
The endoscopic healing rate of reflux esophagitis
The endoscopic healing rate of reflux esophagitis is defined as the proportion of patients with reflux esophagitis who achieve complete mucosal healing. Complete healing is determined by the absence of mucosal breaks upon endoscopic evaluation post-treatment, and the lesion is classified as normal according to the LA classification.
Changes in the severity and frequency of heartburn compared to the baseline
The analysis was performed using a symptom assessment questionnaire. On Day 1 of treatment, participants reported their symptoms experienced during the 7 days prior to randomization. On Days 29 and 57 of treatment, and visits for early trial withdrawal, symptom data were recorded based on the completion status of the 7-day diary cards filled out by participants immediately preceding each visit. The severity of heartburn was evaluated using a 4-point scale, while the frequency of occurrence of heartburn was assessed using a 5-point scale.

The rate of improvement in the severity and frequency of heartburn
Standard for evaluating improvement in severity of individual symptoms: Calculate the average severity score for the 7 days prior to the 4-week and 8-week visits separately. The average score = total of individual scores recorded within 7 days / number of recording days. * Complete remission: The average score drops to 0 points * Improvement: The average score decreases by at least 1 point * No effect: The average score remains unchanged or increases. Standard for scoring the frequency of individual symptoms: 0 points: 0 days; 1 point: 1 day; 2 points: 2-3 days; 3 points: 4-5 days; 4 points: 6-7 days; The improvement rate of individual symptom severity/frequency = (Number of improved cases / Total number of cases) × 100%.
