  Purpose

The purpose of this study is to determine the bioequivalence of fluticasone furoate (FF) inhalation powder (single strip configuration) compared with FF inhalation powder (two strip configuration) and compared with FF / vilanterol (VI) inhalation powder. Fluticasone furoate (FF), is being developed both as a monotherapy for the treatment of asthma and in combination with vilanterol (VI) for the treatment of asthma and Chronic Obstructive Pulmonary Disease (COPD). Thirty healthy male and female subjects will be enrolled in the study to ensure twenty-four evaluable subjects.

Primary Outcome Measures:

From the plasma concentration-time data the following PK parameters will be determined as data permits: Area Under Curve from pre-dose to infinite time (AUC)(0-inf), Area Under Curve from pre-dose to time of last quantifiable concentration (AUC)(0-t), maximum plasma concentration (Cmax)


Secondary Outcome Measures:
  • Pharmacokinetic parameters for Fluticasone Furoate (FF) for all study participants [ Time Frame: 15 time points between pre-dose and 36 hours post-dose in each of the six treatment periods ] [ Designated as safety issue: No ]
    Measurement of amount of FF in the blood of study participants. From the plasma concentration-time data the following PK parameters will be determined as data permits: time to maximum plasma concentration (tmax), half-life (t1/2)

  • Adverse events (AEs) for all study participants [ Time Frame: From the start of first dosing until follow-up (approximately 7 weeks per subject) ] [ Designated as safety issue: No ]

Detailed Description:

Fluticasone furoate (FF; GW685698), a novel corticosteroid, is being developed both as a monotherapy for the treatment of asthma and in combination with vilanterol (VI; GW642444) for the treatment of asthma and COPD. The novel dry powder inhaler (NDPI) will be used to deliver both FF monotherapy and the FF/VI combination. The NDPI can be used with either a single strip or two strips, the single strip being used for FF monotherapy and two strips being used to deliver the FF/VI combination. In some previous FF monotherapy studies, including the phase IIB programme, conducted using the NDPI, the inhaler contained two strips (FF in the first strip and matched VI placebo in the second strip). This two strip configuration has been used for the majority of FF monotherapy treatment arms in previous and ongoing studies. The aim of this study is to determine the bioequivalence of FF monotherapy (single strip) compared with FF monotherapy (two strip), and to determine the bioequivalence of FF monotherapy (single strip) compared with FF/VI, administered via the NDPI. This data will facilitate the inclusion of FF monotherapy (two strip) data and FF/VI combination data to support the FF monotherapy product development. This will be a randomised, open-label, replicate, six-way crossover, single dose study in healthy male and female subjects. Thirty healthy male and female subjects will be enrolled in this study to ensure twenty-four evaluable subjects.

Pharmacokinetic samples will be taken over 36 hours. Safety will be assessed by adverse event (AE) monitoring throughout the study.

Criteria

Inclusion Criteria:

  • 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 parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.

  • 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.
  • History of sensitivity to any of the study medications, including immediate or delayed hypersensitivity to any beta-agonist, sympathomimetic drug, or any intranasal, inhaled or systemic corticosteroid therapy; known or suspected sensitivity to the constituents of the new powder inhaler (i.e. lactose or magnesium stearate), or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates participation.
  • History of severe milk protein allergy.
  • 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.
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 30 day period.
