Eligibility Criteria
Inclusion Criteria:
- Healthy as determined by a responsible physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinically significant abnormality or laboratory parameters significantly outside the reference range for the population being studied may be included only if the Investigator and the and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Male or female between 18 and 65 years of age.
- 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] greater than 40 mIU/mL and oestradiol less than 40 pg/mL [less than 140 pmol/L] is confirmatory).
Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to discontinue HRT to allow confirmation of post menopausal status prior to study enrolment. For most forms of HRT, at least 2 to 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 without use of a contraceptive method.
- Male subjects must agree to use one of the contraception methods alloed by the protocol. This criterion must be followed from the first dosing day until 3 months after the last dose.
- Body weight greater than or equal to 50 kg and BMI within the range 19 to 29.9 kg/m2 (inclusive).
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
- Demonstrates no evidence of mental impairment or co-morbid psychiatric disorders
Exclusion Criteria:
- History or presence of clinically significant cardiac arrhythmias, or other clinically significant cardiac disease.
- QTcB or QTcF greater than 450 msec.
- Subjects, who in the investigator's judgement, pose a significant suicide risk. Evidence of serious suicide risk may include any history of suicidal behavior and/or any suicidal ideation of type 4 or 5 on the C-SSRS in the last 6 months.
- The subject has a positive pre study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines.
- A positive pre study hepatitis B surface antigen (HBsAg) or positive hepatitis C virus (HCV) antibody test result within 3 months of Screening.
- A positive test result for antibodies to human immunodeficiency virus (HIV) 1/2.
- Significant renal abnormality (from medical history or as indicated by laboratory investigations). Additionally subjects with idiopathic haematuria or proteinuria or conditions such as benign orthostatic proteinuria and benign familial haematuria should be excluded from the study.
- Urinary cotinine levels indicative of smoking or history or regular use of tobacco or nicotine containing products within 6 months prior to Screening.
- Subjects, who in the investigator's judgement, pose a significant homicidal risk or have ever been homicidal.
- History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
- The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
- Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
- 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.
- History of regular alcohol consumption within 6 months of the study defined as the following Australian guidelines:
An average weekly intake of greater than 21 units or an average daily intake of greater than 3 units (males), or defined as an average weekly intake of greater than 14 units or an average daily intake of greater than 2 units (females). One unit is equivalent to 270ml of full strength beer, 470ml of light beer, 30ml of spirits and 100ml of wine.
- Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
- Unwillingness or inability to follow the procedures outlined in the protocol.
- Consumption of Seville oranges (including marmalade) and/or grapefruit and/or Chinese grapefruit (pomelo) and/or grapefruit hybrids and/or exotic citrus fruits and/or their fruit juices from 7 days prior to the first dosing day.
- Consumption of red wine from 7 days prior to the first dosing day.
