Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if Aquamin® works as a potential treatment to improve symptoms and if it will induce remission in patients with mild Ulcerative Colitis and extend remission in Ulcerative Colitis in remission.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This pilot study includes individuals with mild ulcerative colitis / ulcerative colitis in remission, and is a randomized, double-blind, placebo-controlled trial with two parallel treatment groups for the first 90 days. Subjects on placebo will be crossed over to Aquamin® after the halfway visit at day 90. Subjects on Aquamin® will continue their treatment until the end.
