The purpose of this study is to verify the safety and tolerability of AG011 and to determine whether AG011 can successfully treat the symptoms of Ulcerative Colitis (UC). Three different dosages will be used in reference to a placebo.~AG011 is an experimental medication. It has been developed as potential treatment for moderately active UC.~AG011 is the clinical formulation of a genetically modified L. lactis that has been engineered to secrete human Interleukin-10 (hIL-10). By delivering hIL-10 locally at inflamed tissue in the intestine, it is believed that, compared to hIL-10 given by injection, the effectiveness may be increased, with fewer adverse effects.~Study medication will be provided in capsule and enema (topical rectal application) forms by ActoGeniX NV.~Subjects will be entered sequentially into one of three dose groups, starting from the lowest dose group. Within each of the first two dose groups, 15 subjects will be entered. Within the highest dose group, 30 subjects will be entered. Within each dose group, subjects will be randomly assigned in a 2:1 ratio to receive either AG011 or placebo for 28 days.~Timely monitoring of safety data is planned for the study, such that subject enrollment can continue without interruption for the purpose of data collection between dose groups. Safety and tolerability will be closely monitored by the Clinical Safety Specialist (CSS) assigned to the study. The CSS will review adverse events and laboratory safety data and report any safety concerns to the Sponsor and a Data Safety Monitoring Committee (DSMC).~At least 8 subjects must have safely completed study treatment for 28 days at a specific dose level, prior to escalation to the next dose group. The DSMC will convene to assess safety data when 8 subjects have completed study treatment for 28 days at the specific dose level. The role of the DSMC for the study will be complete when all subjects in the study have completed study treatment.~For those patients randomized within the active group, UC symptoms could improve. As a result of the information gathered by this study, the knowledge and understanding of UC could improve.
