Study summary

The goal of this clinical trial is to learn if human placenta mesenchymal stem cells (MSC)-derived exosomes work to treat complex perianal fistula in adults without Crohn's disease. The safety of this treatment will also be learned. The main questions it aims to answer are:

  • Does treatment with MSC-derived exosomes lower the number of fistula recurrences in participants?
  • Is treatment with MSC-derived exosomes safe? We will compare treatment with MSC-derived exosomes to the routine treatment which is fistulotomy (surgery to close the fistula) alone to see if MSC-derived exosomes work better to treat complex fistula.

Participants will:

  • Undergo fistulotomy plus MSC-derived exosome injections or fistulotomy alone.
  • Visit the clinic the week after surgery and then every 4 weeks for checkups and tests

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
