Brief Summary:
A Randomized, Double-Blind, Placebo-Controlled, Multiple Dose, Multicenter Study to Assess Efficacy and Safety of SER-287 in Adults with Active Mild-to-Moderate Ulcerative Colitis

Condition or disease Intervention/treatment Phase
Ulcerative Colitis Drug: Vancomycin Pre-Treatment Drug: Placebo for Vancomycin Pre-Treatment Drug: SER-287 Drug: Placebo for SER-287 Phase 2

Detailed Description:
This is a Phase 2B randomized, double-blind, placebo-controlled, multiple dose, multicenter study designed to evaluate the efficacy, safety and microbiome alterations associated with two dose levels of SER-287, after pre-treatment with vancomycin, in adult subjects, age 18-80, with active mild-to-moderate ulcerative colitis (UC).
