Study to Look at and Compare How Inhaled and Intravenous Fluticasone Furoate and GW642444 Are Processed by the Body in Healthy Subjects

• Status: Completed
• Trial end date: 2010-07-15
• Target enrollment: 0
• Participant gender: All

Summary

This study is being done to look at the absolute bioavailability of fluticasone furoate and GW642444 inhalation powder when administered in healthy subjects. Bioavailability is determined by measuring the amount of the dose of inhaled medication that reaches the circulation; the amount of inhaled fluticasone furoate and GW642444 powder will be compared to the medication administered intravenously (where bioavailability is 100%).

• No significant abnormality on the Holter ECG at screening

• FEV1 ≥ 85% predicted at screening.

• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form

• Subjects who are able to use the inhalation device satisfactorily

Exclusion Criteria:

• As a result of medical interview, physical examination or screening investigations, 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

• History of milk protein allergy

• 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

• The subject has taken oral corticosteroids less than 8 weeks before the screening visit

• The subject has taken inhaled, intranasal or topical steroids less than 4 weeks before the screening visit

• History of alcohol/drug abuse or dependence within 12 months of the study

• 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

• Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period

• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.

• The subject has tested positive for HIV antibodies

• A positive pre-study urine drug screen or when randomly tested during the study
