Eligibility
Key inclusion criteria
Inclusion Criteria

* Male/females aged between 18 and 65 years of age inclusive, at the time of signing the informed consent.
* Body weight >=50 kg and body mass index within the range 19.0 - 34.0 kilogram per square meter (inclusive).
* 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 for this definition, "documented" refers to the outcome of the investigator's/designee's review of the subject's medical history for study eligibility, as obtained via a verbal interview with the subject or from the subject's medical records; or postmenopausal defined as 12 months of spontaneous amenorrhea in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) >40 milli-international units per milliliter (MlU/mL) and estradiol < 40 picograms per milliliter (pg/mL) (<147 picomole per liter) is confirmatory. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods in listed in protocol 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 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 without use of a contraceptive method; Child-bearing potential with negative pregnancy test as determined by serum human chorionic gonadotropin (hCG) test at screening or urine hCG prior to dosing AND; Agrees to use one of the contraception methods listed in protocol for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until follow-up; OR has only same-sex partners, when this is her preferred and usual lifestyle.
* Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form
* Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the Investigator agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
* Alanine transaminase, alkaline phosphatase and bilirubin >1.5x upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
* Based on single or averaged corrected QT interval (QTc) values of triplicate ECGs obtained over a brief recording period: QTcF <450 milliseconds.
* Current non-smokers who have not used any tobacco- containing products within 3 months of screening and with a total pack year history of <=10 pack years [number of pack years = (number of cigarettes per day / 20) x number of years smoked].
* Able to use all medical device products included in the study adequately after training

Minimum age

Key exclusion criteria
Exclusion Criteria

* Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
* History of sensitivity to any of the study medications, or components thereof (including milk protein allergy) or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
* A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
* A positive pre-study breath carbon monoxide test or urine drug or breath alcohol screen.
* A positive test for HIV antibody.
* Screening PR interval outside the range 120 to 240msec; or an ECG that is not suitable for QT measurements (eg poorly defined termination of T-wave)
* Pregnant or lactating females or females actively trying to conceive.
* Where participation in the study would result in donation of blood or blood products in excess of 500 millilitres within a 56 day period.
* 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.
* An unwillingness to abstain from strenuous exercise starting 72 hours prior to each dosing day
* An unwillingness to abstain from caffeine- and xantheine- containing products for 24 hours prior to dosing.
* Subject is mentally or legally incapacitated

Part B

* Previous participation in Part A of this study (200921)
