Brief Summary

The Fluticasone Propionate/Salmeterol combination (FSC) at a dose of 100/50 micrograms (mcg) twice daily in DISKUS inhaler (also known as ACCUHALER®, Ddpi) inhaler is a recognised and licensed therapy for the treatment of asthma. GlaxoSmithKline (GSK) is developing the ROTAHALER/ ROTACAPS® (Rdpi) inhaler as an alternative treatment option for asthmatic patients. This study is a Phase I, randomised, double-blind, double-dummy, two- treatment, four-way cross-over (replicate design), two sequence, repeat dose, two centre study in mild to moderate asthmatics to compare the pharmacokinetics and pharmacodynamics of fluticasone proprionate/salmeterol (100/50 mcg) delivered via the Rdpi versus the Ddpi. A total of 58 subjects will be enrolled to ensure 52 subjects complete all dosing occasions. Each subject will be allocated to one of two treatment sequences and will participate in four treatment periods, receiving each of the treatments twice. DISKUS, ACCUHALER, ROTAHALER and ROTACAPS are registered trademarks of GSK groups of companies.

Percent predicted will be calculated using the European Respiratory Society Global Lung Function Initiative reference equations. Subjects must abstain from short acting beta-2 agonists (SABA) use for 6 hours prior to the Screening visit.
• During the screening visit, subjects must either demonstrate the presence of reversible airway disease, defined as an increase in FEV1 of \>=12.0% over baseline and an absolute change of \>=200 millilitres (mL) within 60 minutes following 4 inhalations of albuterol/salbutamol inhalation aerosol (or equivalent nebulized treatment with albuterol/salbutamol solution) or in the absence of reversibility have documented evidence of a physician diagnosed asthma for at least 6 months
• Male/females aged between 18 and 65 years of age inclusive, at the time of signing the informed consent.
• Body weight \>= 50 kilograms (kg) and body mass index (BMI) within the range 18 - 35.0 kilogram/square meter (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 milliinternational units per/millilitre (MIU/mL) and estradiol \<40 picogram/millilitre (pg/mL) (\<147 picomoles per liter \[pmol/L\]) 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, 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 or human chorionic gonadotropin (hCG) test at screening or urine hCG test prior to dosing AND ; Agrees to use one of the contraception methods 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 the follow-up visit.; OR has only same-sex partners, when this is her preferred and usual lifestyle.
