Clinical Trial Summary

The study is intended to assess the relative bioavailability of 2 different abediterol nebulised formulations (test) and the dry powder formulation (reference). The study results will provide information on the pharmacokinetic (PK) profile following use of the 3 devices to be used in further clinical development.

Description:

This study will be an open-label, randomized, 4-period, single-dose, single-center, crossover study with a William's design in healthy subjects (males).

The study will comprise:

1. A screening period of maximum 28 days;

2. Four treatment periods during which subjects will be resident prior to the evening meal the night before dosing with abediterol (Day -1) until at least 48 hours following dosing for collection of PK samples; discharged on the morning of Day 3; and

3. A final safety post-treatment visit within 14 days after the last administration of abediterol.

There will be a minimum washout period of 14 days between each treatment period.

Each subject will be involved in the study for approximately 12 weeks.
