• Male or female subjects, 18 - 65 years of age, inclusive.
• Females of non-childbearing potential.
• Male subjects willing to employ appropriate contraception.
• Except as noted elsewhere, subjects should have no significant known medical conditions other than T2DM that would affect the safety of the subject or the objectives of the study.

• AST and ALT < 2xULN; alkaline phosphatase and bilirubin <=1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). Subjects with Gilbert's syndrome are allowed to participate in the study.

• Systolic blood pressure > 150mmHg or <80mmHg or diastolic blood pressure > 95mmHg or <60mmHg at screening.
• Previous use of insulin as a treatment within 3 months of screening, or for >2 weeks when used for acute illness in the last 12 months prior to screening, or if used for more than 1 year when associated with gestational diabetes mellitus.
• History of: clinically significant symptoms of gastroparesis; symptomatic cholelithiasis or obstructive or inflammatory gallbladder disease within 3 months prior to screening; gastrointestinal disease that could affect fat or bile acid absorption, or the pharmacokinetics or pharmacodynamics of the study drugs, including inflammatory bowel disease, chronic diarrhea, Crohn's or malabsorption syndromes within the past year; gastrointestinal surgery that may affect the pharmacokinetics or pharmacodynamics of the study drugs; or, chronic or acute pancreatitis.
• History of regular alcohol consumption within 6 months.
• Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months.
• Has participated in a clinical trial and has received a drug or a new chemical entity within 30 days or 5 half-lives, or twice the duration of the biological effect of any drug (whichever is longer) prior to the first dose of current study medication.
• Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
• Is taking prohibited medications. In Parts A and B, subjects will not be allowed to wash-off of unapproved anti-diabetic medications in order to qualify for participation in this study. • Subjects must wash out from the following medications during the 7-day period prior to first dose, and must remain off these medications through discharge on Day 2 (Part A) or Day 15 (Part B): all statin agents, fat absorption blocking agents, bile acid sequestrants. Fibrates must be washed out for a 14-day period prior to first dose. • 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.

• 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 physician responsible, contraindicates their participation. This includes sensitivity to heparin or heparin-induced thrombocytopenia, if heparin will be used to maintain catheter patency.
• Where participation in the study would result in donation of blood in excess of approximately 500mL within a 56 day period.
