Experimental drug aims to quiet gut inflammation in ulcerative colitis

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Ability to give consent * Patients with a confirmed diagnosis of UC for \> 3 months * History of ≥ 15 cm of colonic involvement as confirmed by colonoscopy * Disease activity based on calprotectin \> 200 * Allowed medications: mesalamine and sulfasalazine * Patients with primary sclerosing cholangitis are eligible to enroll Exclusion Criteria: * History of uncontrolled hypertension with systolic BP \> 140 and systolic BP \> 90 * Chronic kidney disease as defined by GFR \<55mL/min * Impaired hepatic function (transaminases elevated \> 2.5 x ULN) unless due to PSC * Evidence of C. difficile (Negative test result within 1 month is acceptable) * Infectious Colitis or drug induced colitis * Crohn's Disease or Indeterminate colitis * Decompensated liver disease * Patients who are pregnant or breastfeeding * Use of rectal therapies * Patients who have a confirmed malignancy or cancer within 5 years * Congenital or acquired immunodeficiencies * Other comorbidities including: Diabetes mellitus, systemic lupus * High likelihood of colectomy in the next 2 months * Participation in a therapeutic clinical trial in the preceding 30 days or simultaneously during this trial * Patients with a history or risk of cardiovascular conditions, including arrhythmia, long QT syndrome, congestive heart failure, stroke, or coronary artery disease * Prohibited medications: Vitamin C, prednisone, immune modulators (including but not limited to azathioprine, 6-mercaptopurine, mycophenolate mofetil, tacrolimus, cyclosporine, thalidomide, interleukin-10, interleukin-11, and Omvoh or mirikizumab-mrkz) and biologics within the past six weeks including anti-TNF agents within the past six weeks, vedolizumab within the past six weeks, ustekinumab Risankizumab), a JAKi (tofacitinib or upadacitinib), or Velsipity (etrasimod) within the past 6 weeks. (The aim is to treat people who are having disease activity and just on mesalamine.)
