The Safety and Efficacy of TET Enema in the Treatment of UC

Study Purpose

Colonic Transendoscopic enteral Tubing(TET) is a novel, safe, convenient, and reliable procedure for Fecal Microbiota Transplantation(FMT).This clinical trail aims to evaluate the efficacy and safety of Mesalazine and Compound Glutamine enema in the treatment of Ulcerative Colitis through Colonic TET.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Enema is a conventional treatment for Ulcerative Colitis(UC). Mesalazine is suitable for the patients with mild to moderate UC.But for the UC with extending lesions, the conventional anema with Mesalazine or other medicine can not very effective.Colonic Transendoscopic enteral Tubing(TET) is a novel, safe, convenient, and reliable procedure for Fecal Microbiota Transplantation(FMT).Compared with the conventional enema, which is only used for local administration, the Colonic TET enema can achieve total colonic administration.This study aims to evaluate the efficacy and safety of Colonic TET for UC.Patients in this study will be divided into 5 groups according to certain criteria: the Mesalazine conventional enema group, the Mesalazine TET enema group, the Compound Glutamine conventional enema group, the Compound Glutamine TET enema group, the Mesalazine and Compound Glutamine TET enema group.Each group was given enema for 7 days.The primary outcome measure was the clinical remission efficacy rate in each group. The secondary outcome measure was the safety of TET.
