This is an interventional basic science trial for Diabetes Mellitus, Type 2 Read More

Inclusion Criteria:

• Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the Sirtris Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
• Male between 18 and 55 years of age, inclusive, at the time of signing the informed consent.
• Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods that is permitted in the study. This criterion must be followed from the time of the first dose of study medication until the End of Study Safety Follow-up Visit.
• Body weight ≥50 kilogram (kg) and body mass index (BMI) within the range 18-29.9 kg/m^2 (inclusive).
• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.

Exclusion Criteria:

• Aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase and bilirubin ≥ 1.5x upper limit normal (ULN) (isolated bilirubin >1.5x ULN is acceptable if bilirubin is fractionated and direct bilirubin >35%).
• Have an abnormal 12-lead electrocardiogram (ECG) or an ECG with abnormality considered to be clinically significant in the opinion of the Investigator. Specifically, single QTcB > 450 msec; or QTc > 480 msec in subjects with Bundle Branch Block.
• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
• A positive pre-study drug/alcohol screen.
• A positive test for human immunodeficiency virus (HIV) antibody.
• History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units. One unit is equivalent to 8 gram (g) of alcohol: a half-pint (~240 ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits.
• The subject has participated in a clinical trial and has received an investigational product within the 3 months prior to the first dosing day in the current study.
• Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
• Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and Sirtris Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
• History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the Investigator or Sirtris Medical Monitor, contraindicates his/her participation.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
• Subjects who have asthma, history of asthma, are experiencing flu-like symptoms, or have had an upper respiratory tract infection within two weeks of screening.
• Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.
• Consumption of red wine, seville oranges, grapefruit or grapefruit juice and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication.
