You may be eligible if
Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and electrocardiogram (ECG).
Within 28 or fewer days prior to enrollment, a complete blood count with differential, comprehensive serum chemistry profile, human immunodeficiency virus (HIV) antibody test, and Hepatitis C antibody test will be performed, with the following laboratory values:
Alanine aminotransferase (ALT), alkaline phosphatase and bilirubin less than or equal to upper limit of normal (ULN)
Hemoglobin greater than or equal to 12.0 for men, greater than or equal to11.0 for women
Serum creatinine less than or equal to1.5 mg/dL
Platelet count greater than or equal to 125,000 /cu mm
Absolute neutrophil count greater than or equal to 1250 /cu mm
HIV antibody test negative
Hepatitis C antibody negative
Male or female between 18 and 65 years of age inclusive, at the time of signing the 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 \[in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) \> 40 MlU/ml and estradiol \< 40 pg/ml (\<147 pmol/L) is confirmatory\]. or Child-bearing potential and agrees to use one of the contraception methods listed in the protocol for the time period between screening and dosing of study drugs to sufficiently minimize the risk of pregnancy at that point. Female subjects must also agree to use contraception throughout the study and until two weeks after the last dose of study medications.
Body weight in the range 53-100 kg (inclusive).
Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
You may not be if
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.
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 or 5 half-lives (whichever is longer).
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.
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.
If heparin is used during PK sampling, subjects with a history of sensitivity to heparin or heparin-induced thrombocytopenia should not be enrolled.
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.
Any illicit drug use within the preceding 2 months.
Consumption of red wine, seville oranges, grapefruit or grapefruit juice from 7 days prior to the first dose of study medication.
Pregnant females as determined by positive serum or urine human chorionic gonadotrophin (hCG) test at screening or prior to dosing.
Lactating females.
Unwillingness or inability to follow the procedures outlined in the protocol.
Subjects with a pre-existing condition interfering with normal gastrointestinal anatomy or motility, hepatic and/or renal function, that could interfere with the absorption, metabolism, and/or excretion of the study drugs. Subjects with a history of cholecystectomy, peptic ulceration, inflammatory bowel disease or pancreatitis should be excluded.
History/evidence of clinically significant pulmonary disease.
History of significant renal or hepatobiliary diseases.
History of severe or serious psychiatric disease ever requiring hospitalization, history of suicidal ideation or suicidal attempt, or undergoing psychiatric treatment.
Site investigator suspicion of active tuberculosis (TB).
History of Gilbert's disease.
