About this trial

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

Eligibility Criteria

18 Years - 55 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Be a healthy male or female within the age range of 18 to 55 years.
  • Voluntarily sign a Research Ethics Committee (REC)-approved informed consent form to participate in the study after all relevant aspects of the study have been explained and discussed with the subject.
  • Have Hematology, Coagulation, Clinical Chemistry and Urinalysis test results that are within normal, allowable limits (if out-of-range, must be considered clinically significant to be exclusionary) and performed within 21 days of receiving first dose of test material.
  • Have a BMI (Body Mass Index) between 18.0 and 30.0 kg/m^2.
  • Be clear of any history of HIV and hepatitis B and C.
  • Have no significant disease or clinically significant abnormal laboratory value as deemed by the investigator on the laboratory evaluations, medical history, or physical exam.
  • Have a normal 12-lead ECG or an ECG with abnormality considered to be clinically insignificant.
  • Have the ability to communicate with the investigative site staff in a manner sufficient to carry out all protocol procedures as described.
  • All subjects and their 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.
  • All female subjects must be of non-childbearing potential. For the purposes of this study, this is defined as the subject being amenorrheic for at least 12 consecutive months or at least 6 weeks post-surgical bilateral oophorectomy with or without hysterectomy. (Menopausal status will be confirmed by demonstrating levels of follicle stimulating hormone (FSH) of 20 - 138 mIU/ml and oestradiol < 20 pg/ml at entry. In the event a subject's menopause status has been clearly established (for example, the subject indicates she has been amenorrheic for 10 years), but FSH and/or oestradiol levels are not consistent with a post-menopausal condition, determination of subject eligibility will be at the discretion of the principal investigator following consultation with the sponsor.
  • Subject agrees to refrain from consumption of grapefruits and/or grapefruit juice from 7 days prior to day -1 of treatment visit 1 through to the end of subject's final study visit.

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 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 smokes more than 5 cigarettes a day.
  • Subject has a history of alcoholism, and/or is currently drinking more than three drinks per day [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 (defined as three months from the date of last dose of an investigational medicinal product).
  • 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 products, over-the-counter medication or prescription drug therapy (with the exception of hormone replacement therapy for female subjects) for which 5 times the half-life is longer than 21 days (i.e., the Screening period) prior to enrollment into the study.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

0.5g SRT2104

Arm Description

Cohort 1 (10 males) & Cohort 2 (10 females) must attend the clinic on 4 separate treatment visits during the study; each treatment visit will be one week apart. At each treatment visit, subjects will receive one of the following 4 treatments: A) 0.5g SRT2104 administered as an oral suspension in the fasted state B) 0.5g SRT2104 administered as an oral suspension following consumption of a standard meal C) 0.5g SRT2104 administered as two 0.25g capsules in the fasted state D) 0.5g SRT2104 administered as two 0.25g capsules following consumption of a standard meal. For treatments A and C, subjects will have fasted for at least 10 hours overnight. Water will be restricted from 1h prior to dosing until 1h post dose. A light lunch will be provided 4h post dose. For treatments B and D, subjects will receive SRT2104 within 30 min following the start of consumption of a standardized non high-fat meal (approximately 650 kcal with approximately 30% of calories derived from fat).

Outcomes

Primary Outcome Measures

Characterize and compare the pharmacokinetic profile of a single 500 mg dose of SRT2104 administered as an oral suspension and as a capsule formulation.

Secondary Outcome Measures

Assess the safety and tolerance of SRT2104.

Intervention Type
Drug
Intervention Name(s)
0.5g SRT2104
Intervention Description
SRT2104 will be supplied in two forms: as 0.5g powder which will be prepared by the pharmacist/designee into a liquid suspension and as two hard gelatin capsules, each containing 0.25g SRT2104. The dosing vehicle for the liquid suspension is 1% (by weight) hypromellose acetate succinate in water, which is used as a suspension aid and a dispersant for the SRT2104. Each formulation of test material will be administered orally, in a single dose to the subjects in the fasted state and following consumption of a standard meal. Neither the investigator nor the subjects enrolled will be blinded to treatment assignment.
Primary Outcome Measure Information:
Title
Characterize and compare the pharmacokinetic profile of a single 500 mg dose of SRT2104 administered as an oral suspension and as a capsule formulation.
