Brief Summary

This study is a clinical trial being done to investigate the efficacy of drug BRS201 as a treatment in patients with acute ulcerative colitis. Patients who qualify are adults who have not responded to treatments for their severe ulcerative colitis. Participation in this study will take 12 weeks long and the study is structured as an open-label pilot study in which participants will take the study drug for 4 weeks in the form of an oral medication. Participation may also involve receiving an IV dose of the medication. The study will require participants to attend 8 study visits, all of which will be conducted at a study site. Participation will involve taking an oral medication twice daily, tracking the medication in a log, and getting blood drawn and giving a stool and urine sample for a few lab tests throughout the study. Participants may also undergo a flexible sigmoidoscopy at the beginning and end of the study.

Study Groups

BRS201 Arm

In Group 1 of the study, subjects will take oral study drug at 1.2g daily, PO with 120mg oral butyrate twice daily (240mg daily) for 4 weeks.

In Group 3 of the study, subjects will take oral study drug at 1.2g twice daily, PO (2.4g daily) with 120mg oral butyrate twice daily (240mg daily) for 4 weeks.

In Group 3 of the study, subjects will take oral study drug at 1.2g twice daily, PO (2.4g daily) with 120mg oral butyrate twice daily (240mg daily) for 4 weeks. Subjects will also receive a one time 2.5g dose of study drug at initiation.
