An Investigation of the Pharmacokinetics of GSK961081 and Fluticasone Propionate in Healthy Volunteers

• Status: Completed
• Trial end date: 2011-09-21
• Target enrollment: 0
• Participant gender: All

Summary

In the current study GSK961081 and fluticasone propionate will be administered in a blended formulation from a single device and compared with GSK961081 and fluticasone propionate administered alone and concurrently. This is a single centre, randomized, double-blind, double dummy, single dose, four way cross-over study investigating the pharmacokinetics and pharmacodynamics of GSK961081 and fluticasone propionate when administered alone, concurrently and as a combination blend in healthy subjects.

Criteria

Inclusion Criteria:

1. Male or female between 18 and 50 years of age inclusive, at the time of signing the informed consent.

2. Healthy as determined by the Investigator based on a medical evaluation including medical history, physical examination, laboratory tests and lung function testing. 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 agrees that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures and outcome.

3. A female subject of child bearing potential, is eligible if she agrees to use one of the contraception methods listed in Section 8.1 of the protocol 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 for 5 half-lives after the end of the study (i.e. until after the follow-up visit is complete).

4. Body Mass Index (BMI) within the range 19.0 - 29.9 kilogram per square meter (kg/m2) (inclusive).

5. Aspartate Transaminase (AST), Alanine Transaminase (ALT), alkaline phosphatase and bilirubin less than 1.5 times the upper limit of normal (<1.5xULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin is less than 35%).

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

7. Forced Expiratory Volume in 1 second (FEV1) greater than or equal to 80% predicted and a FEV1/ Forced Vital Capacity (FVC) ratio greater than or equal to 0.7.

8. 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 less than or equal to 10 pack years.

[number of pack years = (number of cigarettes per day/20) x number of years smoked]

Exclusion Criteria:

1. Any clinically relevant abnormality identified at the screening medical assessment (physical examination/medical history), clinical laboratory tests, or electrocardiogram (ECG, 12-lead)

2. History of regular alcohol consumption within 6 months of the study defined as: an average weekly intake of greater than 21 units for males or greater than 14 units for females. One unit is equivalent to 8 grams of alcohol: a half-pint (around 240 millilitres, ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits.

3. QTc value corrected for Bassett or Fredericia [QTc(B) and QTc(F)] at screening greater than 450 milliseconds on an individual ECG, the 3 screening ECGs are not within 10% of the mean QTC value, a PR interval outside the range 120-210 msec or an ECG that is not suitable for QT measurements (e.g. poorly defined termination of the T wave).

4. A supine blood pressure that is persistently higher than 140/90 millimetres of mercury (mmHg) at screening.

5. A supine mean heart rate outside the range 40-90 beats per minute (bpm) at screening.

6. 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: 90 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).

7. Exposure to more than four new chemical entities within 12 months prior to the first dosing day.

8. 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.

9. History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.

10. Where participation in the study would result in donation of blood or blood products in excess of 500 ml within a 90 day period.

11. Pregnant females as determined by positive serum Human Chorionic Gonadotrophin (hCG test) at screening or prior to dosing.

12. Lactating females.

13. Unwillingness or inability to follow the procedures outlined in the protocol.

14. Subject is mentally or legally incapacitated.

15. A history of respiratory disease (i.e. history of asthmatic symptoms) in the last 10 years.

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

17. A positive test for human immunodeficiency virus (HIV) antibody.

18. Urinary Cotinine/ Breath carbon monoxide (CO) levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.

19. Night shift workers
