VE202 in Patients With Mild-to-Moderate Ulcerative Colitis

Randomized, Double-Blind, Placebo-Controlled, Phase 2 Study of VE202 in Patients With Mild-to-Moderate Ulcerative Colitis

A Phase 2 study to evaluate the safety, efficacy, and microbiota changes of VE202 in patients with mild to moderate ulcerative colitis (UC).

A Phase 2 double-blind, placebo-controlled, randomized study to evaluate the safety, efficacy, and microbiota changes of VE202 in biologic-naïve patients with mild to moderate UC. In Parts 1 and 2 of the study, patients will receive VE202 or placebo for 8 weeks or 2 weeks. In Part 3, patients will be followed for safety for 1 year from the start of treatment.

KEY INCLUSION CRITERIA

3. Active mild to moderate UC, as defined by the following:

   1. Disease that extends at least 15 cm from the anal verge
   2. A modified Mayo score of 4 to 8 with: (i.) Mayo endoscopic subscore of ≥ 2 based on screening flexible sigmoidoscopy; (ii.) Rectal bleeding score of ≥ 1

4. Has never received a biologic agent, Janus kinase inhibitor, or sphingosine-1-phosphate modulator for the treatment of UC

5. If receiving corticosteroids, dose must be stable for at least 4 weeks before randomization

6. Doses of other allowable UC medications must be stable for at least 8 weeks before randomization
