Brief 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.
Detailed 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.
