Inclusion Criteria:

• Male/Females aged between 18, 20 for Korean subjects, and 65 years of age inclusive, at the time of signing the informed consent.
• 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 documents that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
• Caucasian, defined as having four grandparents who were descendents of European Caucasians, or Korean origin defined as being born in mainland Korea, having four ethnic Korean grandparents, holding a Korean passport or identity papers and being able to speak Korean. Korean subjects should also have lived outside their respective countries for less than 10 years.
• Body weight >=50 kilogram (kg), >=45 kg for Korean subjects, and body mass index (BMI) within the range 18 - 30 Kilogram per meter square (kg/m^2) (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 (MIU/mL) and estradiol <40 picogram/milliliter (pg/mL) (<147 picomole/liter) is confirmatory]; child-bearing potential with negative pregnancy test as determined by urine Human Chorionic Gonadotropin (hCG) test at screening or prior to dosing AND agrees to use one of the contraception methods as described 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 8 days post-last dose.
• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form
• Alanine aminotransferase (ALT), alkaline phosphatase and bilirubin <=1.5 x Upper Limit of Normal (ULN) [isolated bilirubin >1.5 x ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%].
• Based on single or averaged corrected QT interval (QTc) values of triplicate electrocardiograms (ECGs) obtained over a brief recording period: QT interval corrected for heart rate using Fridericia'sformulas (QTcF) <450 milliseconds (msec).

Exclusion Criteria:

• Criteria Based Upon Medical Histories:
• 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 regular alcohol consumption within 6 months of the study defined as: For Australian (AUST) sites: An average weekly intake of >21 units for males or > 14 units for females. In Australia one unit (=standard drink) is equivalent to 10 grams (g) of alcohol: 270 mL of full strength beer (4.8%), 375 mL of mid strength beer (3.5%), 470 mL of light beer (2.7%), 250 mL pre-mix full strength spirit (5%), 100 mL of wine (13.5%) and 30 mL of spirit (40%).
• 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 GlaxoSmithKline (GSK) Medical Monitor, contraindicates their participation.
• Nasal abnormalities likely to affect the outcome of the study, i.e., nasal septal perforation, nasal polyps, other nasal malformations.
• History of frequent nosebleeds.
• Subjects should be non-smokers, which for this study is defined as having smoked < 10 pack years in their lifetime, and have not smoked in the 6 months prior to the screening visit.

Criteria Based Upon Diagnostic Assessments

• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
• A positive pre-study drug/alcohol screen.
• A positive test for human immunodeficiency virus (HIV) antibody.
• Urine cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.
• Other Criteria:
• Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
• Lactating females.
• 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.
• Any history of nasal surgery which may affect the outcome of the study (i.e., turbinectomy, major nasal reconstruction, septal perforation repair).
• Any history in the past 5 years of either perennial or seasonal allergic rhinitis, or any subject expected to have symptoms of allergic rhinitis during the study.
• Subjects with recent upper respiratory tract infections (URTIs) will be allowed in the study only if their nasal symptoms associated with the URTI have been completely resolved for more than 3 weeks prior to screening
