ClinConnect Summary

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.

• • 1. Systolic BP \<90 mmHg or ≥140 mmHg and diastolic BP \<50 mmHg or
• • ≥90 mmHg
• 2. Heart rate \<50 beats per minute \[bpm\] or \>90 bpm Note: Assessments may be repeated once to confirm values. 8 Any clinically significant abnormalities on 12-lead ECG at screening and first admission to the study unit (first treatment period), as judged by the PI, and defined as:

The period of exclusion begins 3 months after the final dose or one month after the last visit whichever is the longest.
