• 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 in consultation with the Medical Monitor if required agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
• WEIGHT-Body Weight >= 50 kilogram and BMI within the range 19.0 - 34.0 kilogram per square metre (inclusive)
• SEX
• Male,
• Female subject : is eligible to participate if she is not pregnant [as confirmed by a negative serum human chorionic gonadotrophin (hCG) test at screening or urine hCG prior to dosing], not lactating, and at least one of the following conditions applies:
• Non-reproductive potential defined as: Pre-menopausal females with one of the following: Documented tubal ligation, Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, Hysterectomy, Documented Bilateral Oophorectomy
• Postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) and estradiol levels consistent with menopause (refer to laboratory reference ranges for confirmatory levels)]. 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 one of the options listed below in the GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) requirements from 30 days prior to the first dose of study medication and until completion of the follow-up visit.
• GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP)
• This list does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penile-vaginal intercourse on a long term and persistent basis.
• Contraceptive subdermal implant that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label
• Intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label
• Oral Contraceptive, either combined or progestogen alone
• Injectable progestogen
• Contraceptive vaginal ring
• Percutaneous contraceptive patches
• Male partner sterilization with documentation of azoospermia prior to the female subject's entry into the study, and this male is the sole partner for that subject
• These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.
• INFORMED CONSENT Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the consent form and in protocol.
• OTHER
• Capable of using the UD-DPI and the ELLIPTA DPI adequately after training
• Subjects who are current non-smokers, who have not used any tobacco products in the 6 month period preceding the screening visit, and have a pack history of <= 5 pack years.
• Number of pack years = (number of cigarettes per day/20) x number of years smoked

Exclusion criteria

• CONCURRENT CONDITIONS/MEDICAL HISTORY (INCLUDES LIVER FUNCTION AND QTc INTERVAL
• Alanine transaminase (ALT) and bilirubin >1.5x Upper Limit of Normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
• Clinically significant abnormal ECG finding. Significant is defined as any finding that, in the opinion of the investigator, would put the safety of the subject at risk through participation.
• CONCOMITANT MEDICATIONS
• Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study medication, or use of St. John's Wort within 14 days prior to the first dose of study medication. By exception, the volunteer may take paracetamol (<=2 grams/day) any time during the study. However, the Investigator and GSK study team can review medication on a case by case basis to determine if its use would compromise subject safety or interfere with the study procedures or data interpretation
• RELEVANT HABITS
• History of regular alcohol consumption within 2 months of the study defined as:
• For Australian sites: An average weekly intake of >21 units for males or >14 units for females. One unit (= standard drink) is equivalent to 10 g of alcohol: 270ml of full strength beer (4.8%), 375mL of mid strength beer (3.5%), 470mL of light beer (2.7%), 250mL pre-mix full strength spirit (5%), 100mL of wine (13.5%) and 30mL of spirit (40%).
• Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.
• 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.
• Consumption of red wine, Seville oranges, grapefruit or grapefruit juice pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication.
