- Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring obtained at the Screening visit.
The determination of clinical significance will be made by the Investigator and the GlaxoSmithKline (GSK) Medical Monitor and will require that the finding is unlikely to introduce additional risk factors or interfere with the study procedures, or the integrity of the study
- Hemoglobin values at screening greater than the lower limit of the laboratory reference range and less than or equal to 16.0 gram (g)/decilitre (dL) for males and less than or equal to 14.0 g/dL for females
- No significant abnormality on 12-lead ECG at screening, including the following specific requirements:
Ventricular rate >= 40 beats per minute; PR interval <= 210milliseconds (msec); Q waves < 30msec (up to 50msec permitted in lead III only); QRS interval to be >= 60msec and < 120msec; The waveforms must enable the QT interval to be clearly defined; QTcF interval must be < 450msec.
- Body weight >= 50 kilograms (kg) and body mass index (BMI) within the range 19-29.9 kg/meter square (m^2) (inclusive).
- Female and Male:
Female subject is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin [hCG] test), not lactating, and at least one of the following conditions applies:

Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment
- Reproductive potential and agrees to follow the contraception requirement for female subjects from 30 days prior to the first dose of study treatment and until at least five terminal half-lives OR until any continuing pharmacologic effect has ended, whichever is longer after the last dose of study treatment and completion of the follow-up visit

NOTES:
- The QTc is the QTcF interval
- The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined prior to initiation of the study. In other words, several different formulae cannot be used to calculate the QTc for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trial

- History of regular alcohol consumption within 6 months of the study defined as:
An average weekly intake of >14 drinks for males or >7 drinks for females. One drink is equivalent to 12 g of alcohol: 12 ounces (360 mL) of beer, 5 ounces (150 mL) of wine or 1.5 ounces (45 mL) of 80 proof distilled spirits
