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

Study Overview
=================
Brief Summary
-----------------
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
-----------------
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.

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.
