Summary

This is a comparative bioavailability study to compare the pharmacokinetics and pharmacodynamic effects of Fluticasone propionate and Salmeterol delivered in a capsule-based inhaler versus a multi-dose dry powder inhaler in patients with moderate asthma and in patients with moderate to severe Chronic obstructive pulmonary disease (COPD).

Co-primary endpoints will be the area under the curve (AUCτ) measured for plasma Fluticasone propionate (pharmacokinetic) and the pharmacodynamic effects of Fluticasone propionate (weighted mean serum cortisol over 0-12h) on the last day of each 10 day study treatment period. Secondary endpoints will include the following pharmacokinetic parameters for both fluticasone propionate and salmeterol: AUClast, AUC(0-t), Cmax, Cmin, tmax, λz, and t1/2 as well as the pharmacodynamic effects of salmeterol (pulse rate, blood pressure, electrocardiogram \[ECG\], potassium and glucose) and Fluticasone propionate (urine cortisol levels). Safety (adverse events and laboratory abnormalities) will also be assessed as a secondary endpoint.

The study is a randomised, double blind, double dummy, four-period cross-over study. Approximately 60 asthma or COPD patients will be randomised. Patients meeting eligibility criteria will receive Fluticasone propionate/salmeterol 250/50mcg bid, from a capsule-based inhaler and from a multi-dose dry powder inhaler for a period of 10 days each in a randomised order. All patients will receive treatment from each device twice. To maintain the double blind, each patient will receive active treatment and placebo at the same time from two separate devices.

Conditions

Interventions

DRUG

SERETIDE Rotacaps

The study consists of four treatment periods of 10 +/- 1 days each in a cross-over fashion. Each patient will be administered SERETIDE delivered via a capsule-based inhaler (Rotacaps) twice for two treatment periods and a placebo delivered via a capsule-based inhaler (Rotacaps) twice for two treatment periods in a randomised, double-blind, double-dummy fashion. Dosing is twice daily in the morning and evening over the duration of each treatment period.

DRUG

SERETIDE Diskus

The study consists of four treatment periods of 10 +/- 1 days each in a cross-over fashion. Each patient will be administered SERETIDE delivered via a multi-dose dry powder inhaler (Diskus) twice for two treatment periods and a placebo delivered via a multi-dose dry powder inhaler (Diskus) twice for two treatment periods in a randomised, double-blind, double-dummy fashion. Dosing is twice daily in the morning and evening over the duration of each treatment period.
