Heart rate and blood pressure can be retested twice in the supine position at intervals of 5 min on a given day at screening and admission. - Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients including glucose/fructose intolerance for the standard oral glucose tolerance test (OGTT) - Presence or history of clinically significant allergy requiring treatment, as judged by the Investigator. - Donation or loss of greater than 400 mL of blood within the 3 months before first study dose - Subjects who are taking, or have taken, any prescribed, over-the-counter drug (other than 4 g per day paracetamol) or herbal remedies within 14 days, or for which 5 times the medication's elimination half-life will not be completed if longer, before the first dose of study medication. Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the Investigator and Sponsor's medical monitor. Standard dose multivitamins are permitted throughout the study period - Subjects who are currently using glucocorticoids or have a history of systemic glucocorticoid use at any dose within the last 12 months or 3 months for inhaled products - Subjects who are taking, or have taken enzyme inducers within 30 days before the first dose of study medication - Subject is expected to require use of any medication (with the exception of standard dose multivitamins) during the study period - Subject has a history or presence of any medical condition or disease which, in the opinion of the Investigator, could interfere with the conduct of the study or could put the subject at unacceptable risk.
