A Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Administering Multiple Oral Doses of GSK1292263 Alone and With Atorvastatin

A medical history of the following:

* Clinical or angiographic cardiovascular disease, including history or current evidence of coronary heart disease, heart failure, cerebrovascular disease (including stroke and transient ischemic attack \[mini-stroke\]), peripheral vascular disease. Subjects pending diagnostic procedures for any of those conditions at the time of screening will not be eligible for participation.

* Homozygous familial hypercholesterolemia or family history of familial hypercholesterolemia (Part B only). Note: Subjects with heterozygous familial hypercholesterolemia on 80mg atorvastatin who are tolerating this drug well and fulfill the other eligibility criteria may participate in Part A only.

* History of recurrent or unexplained muscle aches (e.g., fibromyalgia), myopathy or myositis, whether or not it is related to treatment with statins or other lipid modifying drugs.

* Renal impairment as defined by a calculated glomerular filtration rate \< 60 mL/min

* History of diabetes mellitus, or history of post-prandial and/or random blood glucose \> 200 mg/dl or fasting glucose \> 125 mg/dL or currently taking diabetes medications to manage fasting glucose levels (e.g., thiazolidinediones, sulfonylureas, insulin, metformin).

* History of pancreatitis within 10 years of screening.

* Any concurrent serious illness (e.g., severe chronic obstructive pulmonary disease, sleep apnea, history of malignancy other than skin cancer within 5 years of initial diagnosis or with evidence of recurrence) that may interfere with a subject from completing the study.

* Current or chronic history of liver disease, or known hepatic or biliary abnormalities.

* Active peptic ulcer disease and/or history of peptic ulcer disease or gastrointestinal bleeding within 12 months prior to screening.

* History of kidney stones within 10 years of screening.

* History of uncorrected thyroid dysfunction or an abnormal thyroid function test assessed by thyroid stimulating hormone (TSH) at Screening. (NOTE: subjects with hypothyroidism on a stable dose of thyroid replacement therapy for at least 3 months prior to screening and who have a screening TSH within the normal range may participate.)

* 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 disease or malabsorption syndromes within the past year.

* Gastrointestinal surgery that may affect the pharmacokinetics or pharmacodynamics of the study drugs.

Note: Subjects may be enrolled in the study if they have had a cholecystectomy three or more months before the time of screening and are stable and asymptomatic.

For females a hemoglobin \< 11.5g/dL, and for males a hemoglobin \< 12.5g/dL.

Current inadequately controlled hypertension (blood pressure \>= 160mmHg systolic or \>= 100mmHg diastolic at screening). If blood pressure medication is changed as a result of screening, blood pressure will be re-measured after 6 weeks and must again meet these criteria.

Significant electrocardiogram (ECG) abnormalities, defined as follows:

Heart Rate \< 50 and \>100bpm PR Interval \<120 and \> 220ms QRS duration \< 70 and \>120ms QTC Interval (Bazett) \> 450ms Or, has clinically significant rhythm abnormalities identified during 24-hour screening Holter assessment. Subjects with left bundle branch block are excluded from the study. Subjects with partial right bundle branch block may be considered for inclusion following consultation with the GlaxoSmithKline (GSK) Medical Monitor. Subjects with Wolf-Parkinson-White (WPW) syndrome are excluded from the study.

Creatinine phosphokinase (CPK) \>= 2x ULN at screening.

A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.

A positive test for HIV antibody.

The subject has a positive pre-study drug-of-abuse screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines.

History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of \>14 drinks/week for men or \>7 drinks/week for women. One drink is equivalent to (12 g alcohol) = 5 ounces (150 ml) of wine or 12 ounces (360 ml) of beer or 1.5 ounces (45 ml) of 80 proof distilled spirits.

Subjects will be excluded if they require treatment with systemic corticosteroids.

Treatment with an investigational drug within 30 days or 5 half-lives (whichever is longer) prior to dosing.

Exposure to more than four new chemical entities within 12 months prior to the first dosing day.

History of sensitivity or untoward reaction to the study medications (GSK1292263, atorvastatin or ezetimibe), or components thereof or a history of drug or other allergy that, in the opinion of the physician responsible, contraindicates their participation.

History of intolerance to statins.

Any change in concomitant medication (including multivitamins, herbal remedies, dietary supplements, and over-the-counter medication) within six weeks prior to screening that is not approved by GSK.

On a diet that may affect study outcomes, or any change in diet, exercise habits or smoking status within six weeks prior to screening or planned change during study (e.g., new exercise program) other than that in the dietary instructions in the Study Procedures Manual.

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, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.

Where participation in study would result in donation of blood in excess of approximately 500mL within a 56 day period.

Subject is mentally or legally incapacitated.

Unwillingness or inability to follow the procedures outlined in the protocol.

Pregnant females as determined by positive urine hCG test at screening or prior to dosing.

Lactating females.

History of sensitivity to heparin or heparin-induced thrombocytopenia.

Consumption of red wine, Seville oranges, grapefruit or grapefruit juice and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication.

Unwilling to abstain from caffeine-or xanthine-containing products from Day -2 until Day 15.
