Brief Summary

The primary objective of this study is to determine the absolute bioavailability of SRT2104 as a 250 mg suspension, and to define the intravenous pharmacokinetics of SRT2104. The secondary objective of this study is to assess the potential systemic metabolite burden of SRT2104, and to provide plasma and urine samples for subsequent metabolite profiling and identification.

Conditions

Diabetes Mellitus, Type 2

Outcome Measures

Primary Outcomes (2)

• Absolute bioavailability of SRT2104 250 mg suspension.

  Time points to measure the bioavailability of SRT2104 oral 250 mg suspension: 0, 1, 2, 3, 4, 5, 6, 8, 10, 12, 18, 24, 48, 72 hrs following administration.

• Define the intravenous pharmacokinetics of SRT2104.

  Time points to define the IV PK of SRT2104: Just before infusion (0); During infusion (5, 10 min); Post infusion (5, 10, 20, 30, 45 min and 1, 2, 3, 4, 6, 8, 10, 12, 15, 21, 45, 69 hours).

Secondary Outcomes (1)

• Potential systemic metabolite burden of SRT2104 following administration.

  At time points: Pre-dose; 0-12 hrs post dose; 12-24 hrs post dose).

• Subjects who have previously been enrolled in this study;
• Subjects who have ever sought advice from or been referred to a GP or counselor for abuse or misuse of alcohol, non medical drugs, medicinal drugs or other substance abuse e.g. solvents;
• Subjects who admit to any current or previous use of Class A drugs such as opiates, cocaine, ecstasy, lysergic acid diethylamide (LSD) and intravenous amphetamines (Subjects who admit to occasional past use of cannabis will not be excluded as long as they have a negative drugs of abuse test and have been abstinent for at least 12 months;)
• Positive drugs of abuse test result (Section 7.8);
• Regular alcohol consumption in males \>21 units per week (1 Unit = ½ pint beer, a 25 mL shot of 40% spirit or a 125 mL glass of wine);

• Radiation exposure from clinical trials, including that from the present study and from diagnostic x rays but excluding background radiation, exceeding 5 mSv in the last twelve months or 10 mSv in the last five years. No occupationally exposed worker, as defined in the Ionising Radiation Regulations 1999, shall participate in the study;
• Clinically significant abnormal biochemistry, haematology or urinalysis as judged by the PI (Section 7.8 )
• History of adverse reaction or allergy to study drug or its excipients, e.g. lactose.
• History of significant allergy. If subject suffers from hayfever they must not have or be expecting to have symptoms during the study period;
• Donation of blood within the previous three months;
• Subjects will be excluded from the study if they are considered by the PI to be at risk of transmitting, thorough blood or other body fluids, the agents responsible for acquired immunodeficiency syndrome (AIDS) or other sexually transmitted disease or hepatitis;
• Positive HBV, HCV or HIV results;
