Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Active Comparator: BRS201 Arm
In Group 1 of the study, subjects will take oral study drug at 2g twice daily, PO (4g daily) with 120mg oral butyrate twice daily (240mg daily) for 4 weeks. In Group 2 of the study, subjects will take oral study drug at 2g twice daily, PO (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. In Group 3 of the study, subjects will repeat the previous conditions of the group that proves to be the most effective. |
Groups 1, 2, and 3 will all contain 6 subjects each, with each subject receiving active study drug and placebo in a 2:1 randomized order; 4 will receive active treatment for the first for four weeks followed by placebo for four weeks, while the remaining 2 will receive placebo for four weeks followed by active treatment for four weeks.

Placebo Comparator: Placebo Comparator: Placebo Arm
In Group 1 of the study, subjects will take oral placebo at 2g twice daily, PO (4g daily) with 120mg oral butyrate twice daily (240mg daily) for 4 weeks. In Group 2 of the study, subjects will take oral placebo at 2g twice daily, PO (4g daily) with 120mg oral butyrate twice daily (240mg daily) for 4 weeks. Subjects will also receive a one time 100mg dose of cyanocobalamin at initiation. In Group 3 of the study, subjects will repeat the previous conditions of the group that proves to be the most effective. |
Groups 1, 2, and 3 will all contain 6 subjects each, with each subject receiving active study drug and placebo in a 2:1 randomized order; 4 will receive active treatment for the first for four weeks followed by placebo for four weeks, while the remaining 2 will receive placebo for four weeks followed by active treatment for four weeks.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Normalization of fecal calprotectin lab measurements
Time Frame: 4 weeks
|
The primary endpoint for this study is the capacity of study drug to normalize fecal calprotectin levels from baseline (week 0) compared to end of active treatment (4 weeks).
|
4 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Simple Clinical Colitis Activity Index (SCCAI)
Time Frame: 12 weeks
|
Clinical symptoms assessed by SCCAI which measures patient reported outcomes on a scale of 0 to 19, where a higher score indicates more severe activity and active disease is a score of 5 or more.
|
12 weeks
|
Plasma nitrite, nitrate, or nitrosothiol
Time Frame: 8 weeks
|
Correlation between changes in plasma nitrite, nitrate or nitrosothiol levels and fecal calprotectin
|
8 weeks
|
Partial Mayo score
Time Frame: 4 weeks
|
Change in partial Mayo scores from baseline to end of active treatment.
The partial Mayo score measures disease activity on a scale of 0 to 9, where a higher score indicates more severe disease activity and a score of 1 or less indicated remission.
|
4 weeks
|
Measurement of sulfur metabolites in urine
Time Frame: 8 weeks
|
Analysis of urine for measurement of thiosulfate, thiocyanate, nitrate and nitrite
|
8 weeks
|
Change in fecal calprotectin lab measurements
Time Frame: 4 weeks
|
Change in fecal calprotectin to < ULN at the end of active treatment
|
4 weeks
