Experimental: Autologous mesenchymal stem cells
Adipose derived, autologous mesenchymal stem cells (AD-MSCs) at a dose of 15 million or 30 million cells will be administered via intra-arterial delivery with interventional radiology to the inferior mesenteric artery in subjects with medically refractory ulcerative colitis.
Drug: Adipose derived, autologous mesenchymal stem cells
Fat tissue will be enzymatically treated and cells will be cultured until a sufficient number are obtained for the treatment protocol.
Other Name: AD-MSC
- Number of participants with treatment-related adverse events [ Time Frame: 24 months ]Evaluate safety by assessment of adverse events defined as worsening (change in nature, severity, or frequency of bowel movements, bleeding per rectum, or tenesmus) of UC present at the time of the study, intercurrent illnesses, abnormal laboratory values (this includes clinically significant shifts from baseline within the range of normal that the investigator considers to be clinically significant) or clinically significant abnormalities in physical examination, vital signs, weight, frequency of bloody stools or change in stools.
- Number of participants with mucosal healing [ Time Frame: 6 months ]Mucosal appearance at endoscopy via Adapted Mayo Score (defined as score of 0 or 1)
- Number of participants with clinical symptom response [ Time Frame: 24 months ]To assess the clinical symptom response of luminal healing induced by the intra-arterial delivery of autologous AD-MSCs for the treatment of UC. Using the validated via Adapted Mayo Score (decrease from Baseline ≥ 2 points and ≥ 30%, including a decrease in rectal bleeding sub-score ≥ 1 or an absolute rectal bleeding sub-score ≤ 1)
- Number of participants with improved healing on pathology [ Time Frame: 24 months ]Histopathology: Improved healing on surgical pathology (colectomy specimen or post-intervention colonic biopsies) as compared to pre-operative endoscopic biopsies
