- Patients that have had a partial colectomy
- Patients that have underlying vasculitis or have been diagnosed with an underlying condition that predisposes to developing blood clots.
- History of cancer including melanoma (with the exception of localized skin cancers)
- Investigational drug within thirty (30) days of baseline
- History of clinically significant auto-immunity (other than UC) or any previous example of fat-directed autoimmunity. Note that auto-immmunity is defined as a systemic immune mediated disease for which the antigen is known or unknown. Autoimmune diseases other than UC are excluded. Extraintestinal manifestations of UC (specifically joint inflammation, eye inflammation, PSC, skin manifestations- i.e. pyoderma gangrenosum, erythema nodosum) will be allowable.
- Allergic to local anesthetics
- Pregnant patients or trying to become pregnant or breast feeding.
- Neoplasia of the colon and preoperative biopsy
- C. Difficile infection within 30 days of study injection
- Diagnosis of indeterminate colitis or suspicion of CD
