About this study

Official title: Formula-to-Syndrome Effect and Pharmacomicrobiomics Mechanism of Colon Delivery of Baitouweng Decoction for Treating Large Intestine Damp-heat Syndrome of Ulcerative Colitis

Baitouweng Decoction is traditionally used to treat large intestine damp-heat syndrome of ulcerative colitis (UC) by oral administration and rectal enema.The project applicant's invention of transendoscopic entral tubing (TET) has been used in Baitouweng Decoction for the treatment of UC across the whole colon, however, the efficacy have not been reported and the underlying mechanism is still unclear. Compared with oral and rectal enema, Baitouweng Decoction by colon TET can improve the therapeutic effect by increasing the concentration of drugs in the whole colon, which need to be verified. This project will reveal the prescription effect and drug-microbiome interaction mechanism of whole colon repeated administration of Baitouweng Decoction in the treatment of UC through clinical randomized controlled studies, deep intestinal dynamic sampling, integrated analysis of multi-omics and TCM prescription metabolomics studies, and provide key scientific basis for the establishment of a new approach of whole colon repeated administration of TCM and a new strategy for the treatment of UC.

Read the detailed description

A multi-center randomized controlled study will be conducted to compare the efficacy differences and multi-omics changes of colon TET, rectal enema and oral Baitouweng Decoction in the control of intestine damp-heat syndrome of UC. Moreover,a group of patients was designed to receive blank carrier solution through colon TET tube. After the study, the patients in this group were given compensation treatment of fecal microbiota transplantation as an ethical protection measure.The colonic TET will be implanted into the intestine and the whole colon will be covered with Baitouweng Decoction. The treatment period is 10 days. The primary outcome measure is the changes of fecal calprotectin before and after oral, colonic TET and rectal enema administration. And the secondary outcomes measure are the changes of disease condition, Mayo score and safety. Deep intestine fluid, stool, blood and urine samples were collected before and after treatment to study the changes of microbiomes, metabolomics and immunoomics. Identify the difference of the key material basis of Baitouweng Decoction and analyze its mechanism comprehensively. The key beneficial and harmful bacteria were identified by comprehensive analysis. A total of not less than 144 subjects are expected to be included and divided into colonic TET treatment group, colonic TET placebo group, rectal enema group, and oral group according to a ratio of 1:1:1:1.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The concentration of fecal calprotecin.

    To compare the concentration of fecal calprotecin before and after oral, colonic TET and rectal enema administration.

    Measured: Baseline; Day 15; Day 53

Secondary outcomes (2)
  1. The change of Mayo score.

    To compare the change of Mayo score before and after oral, colonic TET and rectal enema administration. The Mayo score included the number of bowel movements, blood in the stool, endoscopic findings and overall physician evaluation. The total score was 12 points. The higher the score, the higher the degree of disease activity.

    Measured: Baseline; Day 15; Day 22; Day 53; Day 99.

  2. Incidence of Treatment-Emergent Adverse Events

    The number of adverse reactions that are associated with Baitouweng Decoction reported by subjects from the start of treatment to the end of follow-up.

    Measured: Day 15; Day 22; Day 53; Day 99.
