Trial Title: EUS Evaluation of Perianal and Peri-rectal Fistulizing Crohn's Disease With CERTOLIZUMAB Treatment

Study Design Characteristics:
- Allocation: None
- Intervention Model: None
- Observational Model: COHORT
- Primary Purpose: None
- Time Perspective: PROSPECTIVE
- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
Inclusion Criteria:~* Conventional therapy here indicates non-biologic therapy. Study subjects would have failed conventional and standard regimens of treatment such as immunomodulators (azathioprine, 6-mercaptopurine, methotrexate) or mesalamines or corticosteroids. Certolizumab is actually an approved regimen of treatment for Crohn's disease as patients with perianal fistulas fall under those with moderately to severely active disease. It is not an off-label indication, therefore would not require an IND. The study goal is to look at EUS as a tool to determine how fistula healing occurs with the use of certolizumab which is one of the biologic therapies used to treat fistulizing Crohn's disease. Crohn's disease patients with peri-anal or peri-rectal fistulizing disease. Moderate to severe Crohn's disease patients between the ages of 18 and 70 years with active peri-anal or peri-rectal fistula.~Exclusion Criteria:~* Pre-existing fistula improving on current medical therapy. Contraindication to certolizumab use. Prior use of anti-TNF-alpha.

- Maximum Age: 70 Years
- Healthy Volunteers: f

Study Arms:
- Certolizumab (Type: None): Subjects will take the study drug certolizumab for 8 weeks. They will undergo a endoscopy before study drug and then again after study is complete. The study doctor will be looking for complete closure of the peri-anal fistula identified at visit 1 after the use of certolizumab based on and endoscopic ultrasound (EUS).

Based on this trial design, predict the completion outcome and termination type (if applicable).
