Clinical Trial Summary

A Phase I, single centre, open-label study to investigate the pharmacokinetics (PK), safety and tolerability of single and multiple twice daily doses of inhaled Aclidinium Bromide in healthy Chinese male and female subjects.

Description:

Screening will be performed within 21 days of dosing on Day 1. Eligible participants will be admitted to the trial center on Day -1.

Subjects will receive single dose on Day 1, twice daily regimen is from D5 to D8, and only morning dose will be given on Day 9.

During treatment period, from Day 1 through Day 11 at Visit 2, safety measurements (blood pressure, 12-lead ECG; and AE/SAE monitoring) and blood samples for PK assessments will be collected at predetermined time points.

Clinical laboratory tests (haematology, serum biochemistry and urinalysis) will be performed under fasting conditions at Day -1 at Visit 2.

A follow-up visit will be performed on Day 15.

12. Recent history of a disease or condition that would result in any residual upper respiratory airways/lung inflammatory process or residual limited lung function at the time of Day 1 at Visit 2.

13. History of confirmed COVID-19 infection.

14. Have any gastrointestinal, hepatic, or renal condition that might affect the absorption, distribution, biotransformation, or excretion of aclidinium bromide.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Observed Plasma Concentration (Cmax)	Characterization of Cmax, taken directly from the individual concentration-time curve after single dose or multiple dose.	Day 1 and Day 9
