The subject demonstrates an ECG with values within ranges specified in the protocol at screening or baseline.
The subject is capable of giving written informed consent, which includes the ability to read, comprehend and comply with the protocol requirements and restrictions as described in the consent form.

Exclusion criteria

Has a known immediate or delayed hypersensitivity reaction or idiosyncrasy to any medication that is chemically related to the study drug or a history of drug or other allergy that, in the opinion of the physician responsible, contraindicates their participation in the study.
Has a known allergy to any of the tablet formulation excipients of GSK376501 or pioglitazone (as applicable).
Has sensitivity to heparin or history of heparin-induced thrombocytopenia.
Has a history of alcohol abuse or dependence within 12 months prior to the study.
Has a positive alcohol test at screening or baseline and/or is unwilling to abstain from alcohol for 72 hours prior to the start of dosing until discharged from the clinic and for 72 hours prior to the follow-up visit.

Is unwilling to refrain from the use of tobacco or illicit drugs during the trial, and/or tests positive for urine cotinine or drugs of abuse at screening or at baseline. At minimum, the list of drugs or classes of drugs that will be screened for include the following: amphetamines, barbiturates, benzoylecgonine, benzodiazepines, cannabinoids, cotinine, and opiates.
Where participation in the study would result in donation of blood in excess of 500 ml within a 56 day period.
