A Single Centre Study in Healthy Volunteers to Optimise the Rotacap Formulation and ROTAHALER Device for Delivery of Fluticasone Propionate/Salmeterol

• Status: Completed
• Trial end date: 2012-09-04

Summary

The purpose of this study is to optimise the device and/or formulation of the Fluticasone propionate (FP)/salmeterol (SALM) unit dose powder inhaler (Rotahaler) to achieve drug delivery characteristics comparable to the Fluticasone propionate /salmeterol DISKUS inhaler. The indication is asthma and chronic obstructive pulmonary disease. The study is an open-label, randomised, cross-over, single centre study in healthy volunteers and will be conducted in a maximum of 3 parts, A, B and C. The design is adaptive and pharmacokinetic (PK) data analysis follows each part to enable a decision on whether progression to the subsequent parts is required.

Part A of the study will test an alternative version of the Rotahaler with a low airflow resistance. The study will then test one or more of the following options depending on the outcome of part A. If progressed, part B will test modified Rotacap formulations including: (1) modified blend formulation, (2) reduced capsule fill weights, (3) different capsule types. Part B will also test other versions of the Rotahaler with intermediate airflow resistance. Part C will test the lower strength FP/salmeterol (100/50 mcg or lower) and/or a new unit dose DPI device (BUDI).

A total of 36 subjects will be enrolled in each part to ensure 32 complete. In each cross-over arm, subjects will be administered 7 doses (3.5 days bid) with PK sampling following administration of the 7th dose. A three-day minimum wash-out period will separate each cross-over arm.
