- Masking: TRIPLE
- Phase: PHASE1

Eligibility Criteria:
Inclusion Criteria:~* Women must be of non-childbearing potential. Non-childbearing potential is defined as: Post-menopausal females defined as being amenorrhoeic for greater than one year with an appropriate clinical profile, e.g., age appropriate, history of vasomotor symptoms. However, if indicated, this should be confirmed by estradiol and FSH levels consistent with menopause (according to local laboratory ranges) Pre-menopausal females with a documented (medical report verification) hysterectomy or tubal ligation.~* A negative pre-study urine drug screen. A minimum list of drugs that will be screened includes amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines.~* Negative results for hepatitis C antibodies, hepatitis B surface antigen and HIV at screening, or have documented negative test results within the last 6 months.~* Signed and dated written informed consent prior to admission to the study.~* The subject is able to understand and comply with protocol requirements, instructions and protocol-stated restrictions.~* Subjects with the following clinical laboratory values: ALT and AST \< 2 times the upper limit of normal at screening and prior to the first dose; fasting triglycerides \< 400mg/dL at screening and prior to first dose; bilirubin \< 1.5 times the upper limit of normal at screening and prior to the first dose (total; subjects above this limit may only be included if direct bilirubin is within normal limits).~Other values must be within the normal range or not clinically significant at screening and check-in. Abnormal values, deemed clinically significant by the principal investigator, must be cleared by the medical monitor at GSK.~* Additional inclusion criteria for subjects in Part A: A subject will be eligible for inclusion in Part A of this study only if all of the following criteria apply: Healthy adult subjects aged 18 to 55 years inclusive, male and female subjects of non-childbearing potential.~* Body weight greater than or equal to 50kg for men and greater than or equal to 45kg for women and BMI within the range 19.0 to 30.0kg/m2 inclusive.~* Healthy as judged by responsible physician. No clinically significant abnormality identified on the medical or laboratory evaluation, including 12-lead ECG. A subject with a clinically significant abnormality, or laboratory parameters outside the reference range for this age group may be included only if the Investigator and Sponsor's Medical Monitor considers that the finding will not introduce additional risk factors and will not interfere with the study procedures.~* Part B: A subject will be eligible for inclusion in Part B of this study only if all of the following criteria are met: Subjects with documented type 2 diabetes mellitus diagnosis (diagnosed not less than 6 months; HbA1c less than or equal to 10 % and FPG \< 280 mg/dL at screening) who are either controlled by diet alone or monotherapy for a minimum of 3 months with either oral sulfonylureas, rosiglitazone, metformin, or acarbose. They must be willing/able to discontinue these medications during each dosing occasion for up to 72 hours (from check-in into the research unit until released after the last study assessment for each dosing period).~* Adult men and women between 30 - 60 years inclusive. Women must be of non-childbearing potential.~* BMI within the range 22 35kg/m2 inclusive.~* Subjects taking stable regimens of medications commonly used as prevention in diabetics (aspirin, ACE inhibitors, and statins) will be allowed if their dose regimen(s) remain constant throughout the study period. Concurrent usage of prescribed medications other than the medications listed above may be allowed to continue only with Sponsor's consent.~* No significant concomitant health problems other than type 2 diabetes mellitus and otherwise healthy as judged by a responsible physician.~* Systolic/Diastolic blood pressure: greater than or equal to 80/60 mmHg and less than or equal to 150/95 mmHg at screening.~Exclusion Criteria:~* History or presence of allergy to the study drug or drugs of this class or a history of drug or other allergy that, in the opinion of the physician responsible, contraindicates their participation.~* History or presence of gastrointestinal, hepatic or renal disease, or other condition known to interfere with the absorption, distribution, metabolism or excretion of drugs. Any acute gastrointestinal illness within 2 weeks prior to dosing.~* Use of diuretics, systemic corticosteroids, or any other medication that may result in electrolyte depletion, within 3 weeks of any scheduled dose.~* Blood electrolyte (K, Na, Cl, Mg or Ca or bicarbonate) values outside of the reference range at screening and admission. No deviation will be permitted unless there has been discussion on an individual basis between sponsor and investigator for the following parameters: sodium, potassium, chloride, bicarbonate, calcium and magnesium.~* If participation in the study will result in the subject having donated more than 1,500mL blood (males) or 1,000mL (females) in the previous 12 months and 6. where participation in study would result in donation of blood in excess of 550mL within a 56-day period.~* As a result of the medical interview, physical examination for screening investigations, the Physician Responsible considers the volunteer unfit for the study.~* They have suffered a urinary tract or bladder infection within 4 weeks of the start of the study.~* Abuse of alcohol~* Significant renal disease~* Any clinically significant abnormality identified on the medical or laboratory evaluation, including 12-lead ECG and 24 h Holter monitoring. A subject with a clinically significant abnormality or laboratory parameters outside the reference range for this age group may be included only if the Investigator and Sponsor's Medical Monitor consider that the finding will not introduce additional risk factors and will not interfere with the study procedures~* Participation in a study trial with any drug of new chemical entity within 90 days prior to the start of the study.~* Male subject unwilling to abstain from, or use a condom during sexual intercourse with a pregnant or lactating female; or male subject unwilling to use a condom plus another form of contraception (e.g., spermicide, IUD, birth control pills taken by female partner, diaphragm with spermicide) during sexual intercourse with a female who could become pregnant. Any male subject unwilling to adhere to the above contraceptive criteria from administration of study medication until completion of follow-up procedures.~* 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 and until released after the last study assessment after the last dosing period, unless in the opinion of the Investigator and Sponsor the medication will not interfere with the study procedures or compromise subject safety.~* Part A: A subject will not be eligible for inclusion in Part A of this study if the following applies: Past or present disease, which as judged by the Investigator, may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, hepatic disease, renal disease, haematological disease, neurological disease and endocrine disease.~* Part B: A subject will not be eligible for inclusion in Part A of this study if any of the following criteria apply: Currently requiring insulin therapy, or has been on insulin therapy for the previous 3 months prior to the screening examination.~* Medically unable or unwilling to discontinue their oral antidiabetic medications for up to 72 hours (from check-in into the research unit until released after the last study assessment for each dosing period).~* Past or present disease (other than type 2 diabetes mellitus) as judged by the Investigator, which may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, hepatic disease, renal disease, haematological disease, neurological disease and endocrine disease.
