Official title: A Phase 1b, Exploratory Study to Assess the Safety, Tolerability, Colonic Tissue Exposure, and Anti-Inflammatory Effects of Two Different Doses of SRT2104 in Subjects with Mild to Moderate Ulcerative Colitis
Trial description: The purpose of this research study is to: 1) Test the safety and tolerability of 2 different oral doses of SRT2104 in subjects with ulcerative colitis2) Determine the amount of SRT2104 measured from a single blood sample in addition to colon and/or rectal tissue samples (biopsies) 3) Determine whether SRT2104 has any anti-inflammatory effect on the colon and/or rectum when taken orally for 8 weeks4) Determine whether SRT2104 causes any detectable changes to specific biomarkers. A biomarker is a biological marker (or substance such as a protein) that is used as an indicator of changes in a biological state that corresponds to the risk or progression of a disease.
Primary purpose:
Treatment
Trial design:
Parallel Assignment
Masking:
Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Allocation:
Randomized
Primary outcomes:
Number of participants with adverse events and incidence of adverse events will be used as a measure of safety and tolerability of 50 mg and 500 mg of SRT2104 after repeat dosing for up to eight weeks in subjects with mild to moderate ulcerative colitis
Timeframe: 75 days
SRT2104 concentration in colonic tissue will be measured via endoscopic biopsy after repeat dosing for up to 8 weeks in subjects with mild to moderate ulcerative colitis
Timeframe: 56 days
Secondary outcomes:
Endoscopic scoring of colonic lesions assessed during flexible sigmoidoscopy will be used as a measure of the anti-inflammatory effect of SRT2104 after 8 weeks of treatment in subjects with mild to moderate ulcerative colitis
Timeframe: 75 days
Mayo score and Partial Mayo score will be used as a measure of the anti-inflammatory effect of SRT2104 after 8 weeks of treatment in subjects with mild to moderate ulcerative colitis
Timeframe: 75 days
Simple Clinical Colitis Activity Index (SCCAI) will be used as a measure of the anti-inflammatory effect of SRT2104 after 8 weeks of treatment in subjects with mild to moderate ulcerative colitis
Timeframe: 75 days
Fecal calprotectin will be used as a measure of the anti-inflammatory effect of SRT2104 after 8 weeks of treatment in subjects with mild to moderate ulcerative colitis
Timeframe: 75 days
Histopathologic scoring of colonic tissue biopsies obtained via flexible sigmoidoscopy will be used as a measure of the anti-inflammatory effect of SRT2104 after 8 weeks of treatment in subjects with mild to moderate ulcerative colitis
Timeframe: 75 days
SRT2104 concentration in plasma will be measured after repeat dosing for up to 8 weeks in subjects with mild to moderate ulcerative colitis
Timeframe: 56 days
