Tongjiang Series Prescription Combined With PPIs Descending Ladder Withdrawal in Treating Nonerosive Reflux Disease

July 28, 2020 updated by: Xiyuan Hospital of China Academy of Chinese Medical Sciences

Randomized Double-Blind Clinical Trial of Tongjiang Theory and Syndrome Differentiation Serial Prescriptions Combined With Proton Pump Inhibitors(PPIs)Descending Ladder Withdrawal for the Treatment of Nonerosive Reflux Disease.

Nonerosive Reflux Disease (NERD) is a common refractory gastrointestinal disease. Proton Pump Inhibitors (PPIs), the preferred drug, have poor response, single target and poor acid inhibition effect in some patients in clinical application. Long-term use of PPI can lead to many side effects, even dependency. The main Traditional Chinese Medicine (TCM)syndrome types of NERD are liver-stomach depression-heat syndrome, spleen deficiency damp-heat syndrome and cold-heat complicated syndrome. TCM syndrome differentiation treatment has the advantages of overall regulation and individualized treatment. The purpose of this study is to evaluate the safety and efficacy advantages of syndrome differentiation series prescription combined with PPIs descending ladder withdrawal in the treatment of patients who use PPIs for a long time that can not stop, and to solve the problems of multiple side effects and dependency caused by long-term use of PPIs.

Detailed Description

Nonerosive Reflux Disease (NERD) accounts for about 70% of Gastroesophageal Reflux Disease (GERD), which is a common refractory gastrointestinal disease. Proton Pump Inhibitors (PPIs), the preferred treatment, have the following problems in clinical use: about 50% of patients respond to PPIs only partially or not at all; PPIs has a single target, and the effect of acid suppression alone is poor; long term use of PPIs can lead to dyspepsia, fundic gland polyp, atrophic gastritis, intestinal flora disorders, and even dependency. Liver-stomach depression-heat syndrome, spleen deficiency damp-heat syndrome and cold-heat complicated syndrome account for 80%-91% of NERD's Traditional Chinese Medicine (TCM) syndrome. TCM syndrome differentiation treatment has the advantages of overall regulation and individualized treatment, but it lacks high-level evidence-based medicine evidence. On the basis of previous work, the project plans to establish sub centers in 6 Chinese hospitals, including 180 patients with NERD who meet the requirements to carry out a multicenter, randomized, double-blind, placebo-controlled clinical study, in which 90 subjects in the experimental group received the treatment of syndrome differentiation series of prescriptions combined with PPIs descending ladder withdrawal, and 90 subjects in the control group received the treatment of placebo combined with PPIs descending ladder withdrawal. The therapeutic effects were evaluated from the following aspects: the VAS score of reflow and heartburn, the rate of discontinuation of antacids, the rate of recurrence of NERD symptoms, the score of TCM syndromes and the improvement of gastrointestinal function. The purpose of this study is to evaluate the efficacy advantage and safety of Tongjiang series prescription combined with PPIs descending ladder withdrawal compared with PPIs descending ladder withdrawal alone for patients who use PPIs for a long time that can not stop, so as to obtain evidence-based medical evidence of high-quality TCM syndrome differentiation treatment of NERD, and form an effective and popularized treatment plan to solve the problems of various side effects and dependency caused by long-term use of PPIs.

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
Measure Description
Time Frame
Changes of visual analogue (VAS) scores of reflow, heartburn and other major symptoms
Time Frame: 6 weeks during treatment period, 4 weeks during follow-up period
During the period of taking medicine, the patients recorded the reflow and heartburn attacks (attack times and duration) within 24 hours every day on the symptom diary card, and VAS scores were performed on the reflow and heartburn symptoms. The average score of each symptom in the past week was calculated. The decrease rate of symptom score ≥ 50% after weekly treatment was recorded as response, and the number of response weeks was more than 50% of the whole treatment period, which was considered effective.
6 weeks during treatment period, 4 weeks during follow-up period
Discontinuation rate of acid inhibitors
Time Frame: 6 weeks of treatment
Discontinuation rate of acid inhibitors = Number of drug discontinuation/ Total number of people in each group
6 weeks of treatment
The change of recurrence rate of main symptoms in Nonerosive Reflux Disease
Time Frame: 6 weeks of treatment, 4 weeks during follow-up period
The recurrence rate of the main symptoms, such as heartburn and reflux, was evaluated respectively. The recurrence rate = Number of symptom recurrence / Number of drug discontinuation.
6 weeks of treatment, 4 weeks during follow-up period

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
Measure Description
Time Frame
Changes in secondary symptom scores
Time Frame: 6 weeks during treatment period, 4 weeks during follow-up period
Secondary symptoms such as non cardiogenic chest pain, epigastric pain, burning sensation of epigastrium, belching, cough, asthma and foreign body sensation in pharynx were recorded and scored.
