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

31 de mayo de 2017 actualizado por: Sirtris, a GSK Company

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

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.
