Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Written informed consent from participant
2. Men and women 18-75 years of age with a diagnosis of Crohn's Disease for at least six months duration prior to Day 1
3. Single and/or multi-tract perianal fistula(s) with 2 or fewer openings, that are actively draining
4. Failed at least one medical therapy within the last year including, but not limited to, antibiotics, immunomodulators (6-MP, methotrexate, azathioprine), monoclonal antibodies (adalimumab, certolizumab, golimumab, guselkumab, infliximab, risankizumab, ustekinumab, vedolizumab), or small molecule inhibitors (tofacitinib, upadacitinib)
5. Previous failed surgical intervention, including seton placement at least two weeks prior to screening, or are not candidates for surgical intervention or are not willing to undergo surgical intervention for the management of their fistula
6. Medical therapy for CD stable for at least 2 months prior to Day 1 (Changes in dosing or dosing intervals related to serum drug levels are not permitted)

Exclusion Criteria

1. Lack of informed consent
2. Pregnant woman, woman of childbearing potential without a documented negative urine or serum pregnancy test, or woman who is breast feeding
3. A participant who is unwilling to use medically acceptable contraception methods during participation in study
4. Active perianal abscess or infection at screening or Day 1
5. Clinically significant medical conditions within six months before Day 1 that would, in the opinion of the Investigator, compromise the safety of the participant
6. Confirmed HIV, Hepatitis B, or Hepatitis C infections
7. History of cancer including melanoma (with the exception of localized non-melanoma skin cancers) within one year of screening
8. History of colorectal cancer within 2 years of screening
