Brief summary: The purpose of this study is to compare the maintenance of mild to moderate ulcerative colitis remission with six months of treatment with 1.5 grams of mesalamine pellets each day versus placebo.

Detailed description: This is a phase 3, multicenter, double-blind, randomized, placebo controlled study evaluating the effectiveness and safety of eMG 1.5 g given once daily (QD) compared with placebo in approximately 300 subjects with demonstrated remission from UC. Eligible subjects are randomized in a 2:1 ratio (active:placebo) to receive 1 of 2 treatments: 1.5g eMG QD (four capsules total) or matching placebo capsules QD for 6 months.

The study consists of a Screening phase (completed within 7 days prior to randomization), a Treatment phase (6 months), and a Follow-up visit (2 weeks after end-of-study \[EOS\] visit). The Treatment phase consists of 4 scheduled study visits: Visit 1 (Baseline)/Randomization (Day 1), Visit 2 (Month 1), Visit 3 (Month 3), Visit 4/EOS (Month 6).

Primary objective:

To compare the maintenance of remission from mild to moderate ulcerative colitis (UC) as measured by rectal bleeding and endoscopic mucosal appearance after 6 months of treatment with encapsulated mesalamine granules (eMG) at 1.5 g QD, as compared with placebo.

Secondary objective:

To compare the safety and tolerability of long-term dosing with eMG at 1.5 g QD as compared with placebo in the maintenance of remission from mild to moderate UC.
