Trial overview
Official title: An open-label, randomised, two-way crossover study, to evaluate and compare the pharmacokinetics of fluticasone furoate, administered from a novel dry powder device (repeat dose) and intravenously (single dose), in healthy Caucasian, Japanese, Korean and Chinese subjects
Trial description: Previous studies have shown potentially higher exposure to fluticasone furoate in Japanese subjects compared with Caucasian subjects. The reasons for these potential differences are unclear. Therefore this study is being done to look at and compare how fluticasone furoate is processed by the body in healthy Caucasian, Japanese, Korean and Chinese subjects after inhaled and intravenous administration. The data obtained will be used to help in the clinical development of the drug in Japanese and other East Asian populations.
Primary purpose:
Other
Trial design:
Crossover Assignment
Masking:
None (Open Label)
Allocation:
Randomized
Primary outcomes:
FF Pharmacokinetic parameters: AUC, Cmax, t1/2, tmax for inhaled and intravenous treatments. Volume of distribution (V) and plasma clearance (CL) for intravenous FF
Timeframe: up to 72hr PK sampling periods profiles on 4 separate occasions over a total period of approximately 4-5 weeks
Secondary outcomes:
Pharmacokinetic parameters MRT for both inhaled and intravenous treatments; MAT, AUC(0-t) for 200mcg dose,observed accumulation (Ro) and absolute bioavailability for inhaled treatment
Timeframe: up to 72hr PK sampling periods profiles on 4 separate occasions over a total period of approximately 4-5 weeks
Pharmacodynamics; serum cortisol for 200mcg inhaled FF treatment only: 24 hour weighted mean (on Day -1 and Day 7)
Timeframe: Two 24 hour sampling periods approximately 1 week apart
• Ratio of twenty-four hour urine cortisol to 6-beta-hydroxy-cortisol (on Day -1 of first treatment period only). Plasma 4-beta-hydroxy-cholesterol (single sample, on Day -1 of first treatment period only). Measure of baseline CYP3A4 activity
Timeframe: One collection period of up to 24 hours
• Vital signs, 12-lead ECG, Clinical laboratory tests, forced expiratory volume in 1 second (FEV1) (at screening), peak expiratory flow rate (PEFR), AEs.
Timeframe: Throughout study; approx 10 weeks
Quantity of the total emitted dose (TED), ex-throat dose (ETD) and mass less than 2 micrometer of inhaled FF for each subject, assessed by pharyngometry, inhalation profile, breath hold and lung volume measurements
Timeframe: Throughout study from screening to end of treatment periods; approximately 8 weeks

- Subjects who are able to use the inhalation device satisfactorily
Exclusion criteria:
- As a result of screening medical exam, the principal investigator or delegate physician deems the subject unsuitable for the study. Subjects must not have a systolic blood pressure above 145 mmHg or a diastolic pressure above 85 mmHg unless the Investigator confirms that it is satisfactory for their age.
- Any history of breathing problems in adult life
