NCT ID: NCT01453491

Last Updated: 2017-06-01

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 17 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2012-02-13
• Study Completion Date: 2013-03-18

Brief Summary

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.

Conditions

Colitis, Ulcerative

Study Design

• Allocation Method: RANDOMIZED

Study Groups

50mg SRT2104

Single oral administration of 50mg SRT2104 study drug will be supplied as 25 mg and 250 mg capsules and will be taken orally once daily for 56 days. SRT2104 is to be taken at approximately the same time every morning, in the fasted state. Water is permitted ad libitum. Subjects are allowed to consume liquids but should refrain from eating solid food for approximately 1 hour after dosing.

Group Type: EXPERIMENTAL

SRT2104

Intervention Type: DRUG

SRT2104 drug substance is a new chemical entity which is supplied as a fine, yellowish/amber powder. The SRT2104 investigational product is prepared by packing 25mg or 250 mg of micronized SRT2104 powder with no additional additives into a size 00 opaque, hard gelatin capsule. All subjects will be provided with one dosing bottle per day that contains two 25 mg or 250 mg SRT2104 capsules for oral ingestion.

500mg SRT2104

Single oral administration of 500mg SRT2104 will be taken orally once daily for 56 days. SRT2104 is to be taken at approximately the same time every morning, in the fasted state. Water is permitted ad libitum. Subjects are allowed to consume liquids but should refrain from eating solid food for approximately 1 hour after dosing.
