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

2017년 5월 31일 업데이트: 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.

  • Presence of chronic liver disease, with the exception of known Gilbert's syndrome
  • A positive pre-study Hepatitis B surface antigen, Hepatitis C antibody or HIV at Visit 1
  • Past or present disease that is judged by the investigator to have the potential to interfere with the study procedures or compromise the subject's safety
  • History of malignant neoplasm within the past 5 years, other than localized basal cell carcinoma, squamous cell carcinoma, or carcinoma in situ that has been resected or definitively treated with standard approaches
  • Prior diagnosis of flat colonic dysplasia or unresected raised colonic dysplasia (adenoma-like lesion or mass)
  • History of regular alcohol consumption within 6 months of the Screening (Visit 1) defined as an average weekly intake of >14 drinks (one drink is defined as 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of 80 proof distilled spirits) or presence of recreational drug abuse or dependence
  • Known bleeding disorders
  • Bowel surgery within 12 months prior to Visit 1
  • History of colectomy or partial colectomy
  • Treatment with oral aminosalicylates at doses >4.8 g per day or aminosalicylate dose modification (except transient shift lasting up to 3 days) within 4 weeks prior to study Day -5 (Note: if on this type of treatment, the dose must remain constant throughout the study treatment period)
  • Treatment with rectal aminosalicylates at any dose within 2 weeks of study Day -5
