NCT06776029

Brief Summary

The goal of this single-arm trial is to learn if Fecal Microbiota Transplantation (FMT) works to treat hemorrhagic radiation-induced proctopathy. The main questions it aims to answer are:

  • Dose FMT alleviate the symptom of severe rectal bleeding?
  • Dose FMT improve the endoscopic findings of proctopathy? Participants will:
  • Take fecal microbiota capsules by 8 sessions over a 12-week period.
  • Visit the clinic once every 4 weeks for checkups and tests.
  • Keep a diary of their symptoms and the number of times they use other supportive care.

Outcome Measures

Primary Outcomes (1)

  • Number of participants with mild rectal bleeding (grade 0-1)

    The symptom of rectal bleeding will be assessed by LENT-SOMA scales

    At the time of 12 weeks since the start of treatment

Secondary Outcomes (2)

  • Number of participants with mild rectal bleeding (grade 0-1)

    At the time of 24 weeks since the start of treatment

  • Number of participants with improved colonoscopic findings

    At the time of 12 and 24 weeks since the start of treatment

Study Arms (1)

Fecal Microbiota Transplantation

EXPERIMENTAL

Fecal microbiota capsules are given by 8 sessions over a 12-week period, with the initial 3 sessions every other day in the first week and the subsequent sessions every two weeks. The FMT regimen involves oral intake of 40 capsules per session. The best supportive care is performed when necessary, including oral medicine, enema, blood transfusion, and endoscopic procedures.

Biological: Fecal Microbiota Transplantation Capsule

Interventions

FMT is delivered via oral capsules. Fecal microbiota capsules are given by 8 sessions over a 12-week period, with the initial 3 sessions every other day in the first week and the subsequent sessions every two weeks. The FMT regimen involves oral intake of 40 capsules per session. The best supportive care is performed when necessary, including oral medicine, enema, blood transfusion, and endoscopic procedures.
