A Phase 1b Study to Assess the Safety and Anti-inflammatory Effects of Two Different Doses of SRT2104 in Patients With Ulcerative Colitis

Completed · Phase 1

Conditions studied: Colitis, Ulcerative

In brief

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 colitis * 2\) 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 weeks * 4\) 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.
