Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study investigates the safety, pharmacokinetics and effects of GSK1292263 when taken alone or when co-dosed with atorvastatin to subjects with dyslipidemia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This compound has been studied in healthy subjects and subjects with type II diabetes and is now being studied in subjects with dyslipidemia. Because many patients with dyslipidemia are on statins, it is important to study how GSK1292263 behaves when taken with a potent statin, atorvastatin. The cholesterol lowering drug, ezetimibe, is included for comparison.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy adult males and females of non-child-bearing-potential, aged 18-75 years who is capable of giving informed consent.
* A female subject is eligible to participate if she is of:

* Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea. In questionable cases, a blood sample with simultaneous follicle stimulating hormone (FSH) \> 40 MlU/ml and estradiol \<40 pg/ml (\<140 pmol/L) is confirmatory in the absence of a clear post-menopausal history.
* Females on hormone replacement therapy (HRT) must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study.
* Male subjects must agree to use one of the contraception methods listed in the protocol. This criterion must be followed from the time of the first dose of study medication until seven days following the last dose.
* Body weight \> 50 kg (110 pounds) and body mass index (BMI) between 19.0 and 39.0 (inclusive).
* Part A: (i) Subjects who are on 80mg or 40mg atorvastatin for \>= 4 weeks and are tolerating the drug well, or (ii) Subjects not on lipid-modifying therapy who have a fasting low density lipoprotein cholesterol (LDLc) \>= 130mg/dL.
* In Part B at Screening: Subjects who are on statins or Vytorin treatment for \>= 4 weeks.
* Part B at the end of the 4 week washout: Subjects who have a fasting LDL cholesterol of \>=120mg/dL and \<=180mg/dL and fasting triglycerides of \>=100mg/dL and \<=400mg/dL.
* Part B at the end of the 4 week run-in on atorvastatin: Subjects who are tolerating well atorvastatin 10mg or 80mg (as determined by the Investigator).
* Part B: Subjects must be willing to discontinue statins or Vytorin for the duration of the study.
* Liver enzymes, AST and ALT \< 2x upper limit of normal (ULN); 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.

* 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 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.

* 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.
