The Study of Chinese Medicine for the Treatment of Chronic Atrophic Gastritis
Condition: Chronic Atrophic Gastritis
MeSH terms: Gastritis; Gastritis, Atrophic; Atrophy
Study type: Interventional

Summary: 
      The purpose of this study is to evaluate efficacy of Chinese medicine treatment for chronic
      atrophic gastritis. It is a multi-center, randomized, placebo-controlled trial.
    

Detailed description: 
      A prospective, double-blind, randomized, placebo-controlled, multi-center trial is carried
      out in this study.The sample size is 468 patients ( 312 in treatment group, 156 in control
      group). The investigators will screen the patients for inclusion according to the inclusion
      and exclusion criteria. All patients detect of H.pylori, undergo upper digestive endoscopy
      and biopsies for histological investigation. Patients infected of H.pylori must receive
      H.pylori eradication therapy under the guidance of Kyoto global consensus report on H.pylori
      gastritis. Then they are assigned to treatment group or control group with an allocation
      ratio of 2:1. Patients intreatment group take the traditional Chinese medicine prescription,
      while the control group take simulate granule of the prescription. Both two groups are under
      symptomatic treatment. Treatment duration lasts 24 weeks. Investigators also follow up
      another 24 weeks. Histological changes are used as the primary outcome index. Endoscopy
      findings, symptoms are assessed. Serum level of pepsinogen and patient-reported outcome
      instrument are also administered during the study. All biopsy specimens are collected to
      build the biological specimen bank. Central blinded histological assessment (Histological
      diagnosis is determined independently by three experienced pathologists who are blinded to
      the information of the patients.) are used to insure the accuracy and consistency.
      Tele-medicine and information management system is established to help achieve follow-up
      interviews.

      Random numbers are generated by SAS 9.4 software. The subjects, caregivers, investigators and
      outcomes assessors in this study are all blinded.
