About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled, Phase I Clinical Study to Assess the Pharmacokinetics, Safety and Tolerability of SRT2104 Administered as Single and Multiple Doses in the Fed State to Normal Healthy Male Volunteers
The purpose of this study is to assess the pharmacokinetic profile, safety, and tolerability of SRT2104 following administration of single and multiple oral doses (once a day for seven days) at a single dose level (2.0 g/day) to healthy male volunteers in the fed state.
Read the detailed description
This is a prospective, single center, clinical study of SRT2104 administered orally; a randomized, inpatient/outpatient study to assess the safety and pharmacokinetics (PK) of SRT2104 in healthy male volunteers. Ten (10) male subjects, aged 18-60, who fulfil the inclusion/exclusion criteria, will be enrolled in this study. Subjects will receive either a dose of 2.0 g SRT2104 (administered as eight 250 mg capsules) or placebo on eight occasions during the study; once as a single dose (study day 1) during Treatment Period 1, and once per day for seven consecutive days (study days 15 to 21) during Treatment Period 2. Every administration of SRT2104 will be in the fed state (i.e. within 30 minutes following the start of consumption of a standard meal).
Subjects will be asked to sign the informed consent form at the screening visit. If eligible and willing to participate, subjects will enter into the study. Subjects will be required to attend the research unit on eight separate occasions during the study, in addition to the screening visit. Treatment Period 1 requires the subject to attend the unit for two consecutive overnight stays (Day -1 and Day 1), after which subjects will be discharged from the unit on Day 2 (following the 24 hr post-dose PK blood sample). Subjects will then be required to return to the unit for PK blood samples to be obtained on Day 3 (48 hr post-dose), Day 4 (72 hr post-dose) and Day 8 (168 hr post-dose). Following a washout period of seven days, subjects will be required to attend the unit for Treatment Period 2, which will involve eight consecutive overnight stays (Days 14 to 21), after which subjects will be discharged from the unit on Day 22 (following the 24 hr post-dose PK blood sample). Subjects will then be required to return to the unit for PK blood samples to be obtained on Day 23 (48 hr post-dose), Day 24 (72 hr post-dose) and Day 28 (168 hr post-dose).
Subjects will be randomised 8:2 (active:placebo) to receive one of the following two treatments for the duration of the study:
- 2.0 g SRT2104 administered as eight 250 mg hard gelatin capsules B. Eight placebo capsules
Water will be restricted from 1 hour prior to dosing until 1 hour post-dose. Subjects will receive SRT2104 within 30 minutes following the start of consumption of a standardized non-high-fat meal (approximately 650 kcal with approximately 30% of calories derived from fat). A light lunch will be provided 4 hours post-dose, an evening meal approximately 8 hours post dose and a snack approximately 12 hours post dose.
Subjects will be discharged from the study on Day 28 after the 168 h PK sample has been obtained, all required safety assessments have been performed, and the subject has been confirmed clinically stable by the investigator/identified sub-investigator.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SRT2104Drug
2.0 g of SRT2104 will be supplied in hard gelatin capsules each containing 250 mg SRT2104. SRT2104 will be administered within 30 minutes following the start of consumption of a standardized non-high-fat meal (approximately 650 kcal with approximately 30% of calories derived from fat). The eight capsules of SRT2104 will be orally-administered with approximately 200 mL water.
PlaceboDrug
Placebo will be supplied in hard gelatine capsules containing an appropriate amount of placebo. Placebo will be administered within 30 minutes following the start of consumption of a standardized non-high-fat meal (approximately 650 kcal with approximately 30% of calories derived from fat). The eight capsules of placebo will be orally-administered with approximately 200 mL water.

What is being measured
The primary outcome is the main question the study is designed to answer.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing SRT2104 in people with Diabetes Mellitus, Type 2, run by GlaxoSmithKline at 1 site in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To assess the plasma pharmacokinetic profile of SRT2104 following administration of single and multiple oral doses (once a day for seven days) at a single dose level (2.0 g/day) to healthy male volunteers in the fed state. (time frame: Plasma samples will be collected pre-dose (0 h) and at the following time points following dosing on Days 1 and 21: 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 15, 24, 48, 72 and 168 h post-dose.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00933062, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2017; AzTrials last refreshed its copy on 8 Nov 2026.
