- Registration Number
- NCT04037072
- Lead Sponsor
- Fox Chase Cancer Center
- Brief Summary
This study evaluates Mitomycin C as treatment for dysphagia in adult subjects with documented complex esophageal anastomotic strictures. Patients will be randomized in a double-blinded fashion to topical application of normal saline (NS) or Mitomycin C (MMC) at the time of time of index procedure.

Inclusion Criteria
- Ability to understand and willingness to sign a written informed consent and HIPAA consent document
- Patients must have symptomatic (dysphagia ≥2), treatment naïve complex esophageal anastomotic stricture (length >2 cm or diameter ≤9mm).
- Age ≥ 18
- Esophago-gastro or esophago-jejunal anastomosis with or without having undergone neoadjuvant or adjuvant radio-chemotherapy
- Any patient taking antiplatelet agents such as Plavix, Effient, Brilinta, Aggrenox must be able to hold the drugs 5 days prior to dilation and may resume 3 days after the dilation.
- Any patient on vitamin K antagonists such as warfarin must be able to hold the drugs 5 days prior to dilation and may resume 3 days after the dilation. INR should be checked for such patients at least 24 hours before dilation and it must be < 1.5
- Patients taking direct thrombin inhibitors such as Pradaxa, Angiomax must be able to hold the drugs 5 days prior to dilation and may resume 3 days after the dilation
- Patients taking Factor Xa inhibitors must be able to hold the drugs 2 days prior to dilation and may resume 3 days after dilation
- Patients taking GIIB/IIIA inhibitors must be able to hold the drugs1 day prior to dilation and resume 3 days after the dilation.
- Patients taking unfractionated heparin must be able to hold the drug 6 hours before dilation and low molecular weight heparin must be held 24 hours before dilation. Unfractionated heparin may resume immediately after the dilation while low molecular weight heparin may resume 3 days after dilation
Exclusion Criteria
- Patients with malignant strictures
- Patients with non-complex benign strictures.
- Patients with anastomosis creation within ≤ 2 weeks
- Patients with suspected gastrointestinal perforation or leak that could result in extraluminal extravasation of Mitomycin C
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- Pregnant or breast feeding. Refer to section 4.4 for further detail.
- Patients receiving systemic chemotherapy during the treatment of esophageal stricture.
