Dataset from An Open-label, Randomised, Cross-over, Single Dose Study in Healthy Volunteers to Evaluate the Unit Dose Dry Powder Inhaler (UD-DPI) With Four Different Formulations for the Delivery of Fluticasone Furoate and to Compare the Pharmacokinetic Profile With the Fluticasone Furorate ELLIPTA Presentation

This is an open-label, five- period, cross-over, randomized, single dose, single centre study in healthy subjects. This is the second clinical study for the UD-DPI. This study will ascertain whether the Pharmacokinetics (PK) systemic exposure [in terms of area under the plasma concentration-time curve (AUC) and maximum observed plasma concentration (Cmax)] of FF delivered via the UD-DPI is comparable to the systemic exposure of FF delivered via the ELLIPTA Dry Powder Inhaler (DPI). For this reason four treatment doses consisting of three dose strengths and 2 percentage blends will be assessed when delivered via the UD-DPI. This study is designed to compare the pharmacokinetic profile of various doses and blends of FF administered via UD-DPI and relative to FF administered via ELLIPTA DPI. Subjects will be screened 28 days prior to study initiation. During each treatment period, subjects will be at study site from evening prior to dosing until completion of the 48 hour post-dose PK sample collection on Day 3. Minimum 7 days washout will be between treatments after completion of all five treatments and the follow-up visit will be conducted 7-14 days post last dose. Duration of study is 13 weeks.
