Outcome Measures
Primary Outcomes (1)
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.
Up to 8 weeks
Secondary Outcomes (7)
The endoscopic healing rate of reflux esophagitis
Up to 4 weeks
Changes in the severity and frequency of heartburn compared to the baseline
Up to 8 weeks

Study Arms (2)
Anaprazole
EXPERIMENTALAnaprazole 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
ACTIVE COMPARATORRabeprazole 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.
Interventions
Anaprazole 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 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.
Eligibility Criteria
You may qualify if:
- 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.
You may not qualify if:
- 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).
- Patients with a history of Zollinger-Ellison syndrome, achalasia of the cardia, secondary esophageal motility disorders, irritable bowel syndrome, inflammatory bowel disease, or other gastrointestinal functional disorders.
- Patients with a history of malignant tumor or having received treatment for malignant tumor within 5 years prior to randomization.
- Patients with a history of mental illness or a history of drug or alcohol abuse within 12 months prior to screening.
- Patients who tested positive for HIV, HBsAg, and/or HCV antibodies during screening.
- Patients with malignant tumors or a predisposition to malignancy in the stomach or esophagus.
- Patients with abnormal liver function: AST and/or ALT levels ≥2.0×ULN, and/or total bilirubin (TBIL) levels ≥1.5×ULN.
- Patients with abnormal renal function: Serum creatinine levels ≥1.5×ULN, blood urea or blood urea nitrogen levels ≥1.5×ULN.
- Patients with clinically significant ECG abnormalities, including QTc interval prolongation (QTcF ≥450 ms for men and QTcF ≥470 ms for women).
- Patients with poorly controlled diabetes or hypertension.
- Patients who were unable to undergo esophagogastroduodenoscopy (EGD).
- Patients with a known allergy to the components or ingredients of Anaprazole or Rabeprazole.
