A diagnostic tool that identifies biomarkers that predict response prior to and during induction of ozanimod will have a major impact on improving outcomes in UC patients. Using SOMAscan from SomaLogic (Boulder, CO), our study aims to discover serum protein biomarkers in UC patients that predict response to ozanimod and to gain insight into the pathophysiological mechanisms underlying ozanimod response.

Inclusion Criteria:

1. Patients ≥18 years of age with established diagnosis of UC starting ozanimod therapy as part of their clinical care
2. Patients with moderate to severe UC, determined by a 3-component Mayo score of 5-9 with an endoscopic subscore ≥ 2.Endoscopy must be performed within 90 days of ozanimod initiation
3. Elevated CRP (greater than upper limit of normal on assay) and/or fecal calprotectin (>250 mcg/g) within 90 days of drug initiation

Exclusion Criteria:

1. Diagnosis of Crohn's disease or indeterminate colitis
2. Total (procto)colectomy
3. Ileoanal pouch anastomosis
4. Current ileostomy or colostomy
5. Untreated Clostridium difficile infection
6. Known pregnancy
