This is an interventional basic science trial for Diabetes Mellitus, Type 2
Eligibility Criteria
Inclusion Criteria:

- Have a normal 12-lead ECG or an ECG with abnormality considered to be clinically insignificant. Specifically, the QTcB must be ≤ 450 msec, and no evidence of bundle branch block must be present.
- Have the ability to communicate with the investigative site staff in a manner sufficient to carry out all protocol procedures as described.
- Subject and his partner must agree to use an acceptable double barrier method for birth control from the Screening visit through 3 months after the last dose of test material.
Exclusion Criteria:
- Subject has had a major illness in the past three months or any significant ongoing chronic medical illness that the Investigator would deem unfavorable for enrollment.
- Subject has renal or liver impairment.
- Subject has clinically significant findings on Screening 24 hour 12-lead Holter.
- Subject has a history of gastro-intestinal surgery or has a current gastrointestinal disease which may influence drug absorption.
- Subject has a history, within 3 years, of drug abuse (including benzodiazepines, opioids, amphetamine, cocaine, and THC) or a positive drug result at Screening.
- Subject has a history of smoking, within 3 months, or is currently a smoker.
- Subject has a history of alcoholism, and/or is currently drinking more than three drinks per day on a regular basis [one drink is equal to one unit of alcohol (one glass of wine, half a pint of beer, one measure of a spirit)].
- Subject has participated in a clinical trial within the past three months.
- Subject has a history of difficulty in donating blood or accessibility of veins in left or right arm.
- Subject has donated blood (one unit or 350 mL) within three months prior to receiving test material.
- Subject is taking herbal and dietary supplements or prescription drug therapy for which 5 times the half-life is longer than 21 days (i.e., the Screening period) prior to enrollment into the study. Please note: subjects must refrain from taking herbal or dietary supplements for the duration of the study.
- Unwillingness or inability to follow the procedures outlined in the protocol.
- Subject is mentally or legally incapacitated.

Cohort 1 will be administered at approximately the same time every dosing day after fasting for 10hrs. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving 25 mg SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving 25 mg SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study. The other cohorts will be dosed sequentially allowing for a comprehensive safety assessment prior to initiation of an escalated dose in a subsequent cohort.
Cohort 2 will be administered at approximately the same time every dosing day after fasting for 10hrs. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving 75 mg SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving 75 mg SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study. The other cohorts will be dosed sequentially allowing for a comprehensive safety assessment prior to initiation of an escalated dose in a subsequent cohort.
Cohort 3 will be administered at approximately the same time every dosing day after fasting for 10hrs. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving 250 mg SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving 250 mg SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study. The other cohorts will be dosed sequentially allowing for a comprehensive safety assessment prior to initiation of an escalated dose in a subsequent cohort.
Cohort 4 will be administered at approximately the same time every dosing day after fasting for 10hrs. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving 500 mg SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving 500 mg SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study. The other cohorts will be dosed sequentially allowing for a comprehensive safety assessment prior to initiation of an escalated dose in a subsequent cohort.
Cohort 5 will be administered at approximately the same time every dosing day after fasting for 10hrs. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving 1000 mg SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving 1000 mg SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study.

Cohort 6 will be administered at approximately the same time every dosing day after fasting for 10hrs. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving 2000 mg SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving 2000 mg SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study. The other cohorts will be dosed sequentially allowing for a comprehensive safety assessment prior to initiation of an escalated dose in a subsequent cohort.
Cohort 7 will be administered at approximately the same time every dosing day after fasting for 10hrs. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving 3000 mg SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving 3000 mg SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study. The other cohorts will be dosed sequentially allowing for a comprehensive safety assessment prior to initiation of an escalated dose in a subsequent cohort.
Cohort 8 will be administered at approximately the same time every dosing day and 30 minutes following the start of consumption of a standardized high-fat meal. Two subjects will be dosed on Day 1 of the single dose period with one subject receiving SRT2379 and one subject receiving placebo. The remainder of subjects in this cohort will be dosed on Day 2 of the single dose period with five subjects receiving SRT2379 and one subject receiving placebo, assuming that no significant safety issues arise in the two subjects dosed on Day 1. Subjects will remain on a fixed dose of test material for all dosing days in the study. The dose of SRT2379 administered to subjects in the fed state is planned to be 500 mg, however this may be modified upwards or downwards following evaluation of safety and pharmacokinetic data from earlier cohorts. The fed cohort will be the final cohort dosed in the study.
