A Single Dose PD & PK Study With Two Formulations of Abediterol in Patients With Asthma

• Status: Completed
• Trial end date: 2016-11-29
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to investigate the pharmacodynamics of single doses of abediterol given by 2 different devices in participants with asthma. Abediterol (AZD0548) is a potential for once daily treatment of asthma and chronic obstructive pulmonary disease (COPD) in fixed dose combination (FDC) with an inhaled corticosteroid (ICS) or a novel anti-inflammatory agent. The aim of the clinical studies is to enable further investigations in participants with asthma and COPD to evaluate and develop abediterol as an effective long acting bronchodilator with an acceptable safety profile compared to other inhaled bronchodilators on the market, for the treatment of asthma and COPD.

5. On stable dose of ICS or ICS/LABA FDC, for at least 1 month prior to Visit 1, at the doses approved in the country of enrolment.

6. Prebronchodilator FEV1 at Visit 2 ≥40% and ≤85% of predicted (1 repetition of the test is allowed before screen failure).

11. Patient must agree to all restrictions during the study.

Exclusion Criteria:

1. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).

2. Participation in another clinical study with an IP during the last 3 months.

3. Known or suspected hypersensitivity to the IP or excipients, including lactose (Note:

lactose intolerance is not an exclusion).

8. Treatment with biologicals such as monoclonal antibodies or chimeric biomolecules including omalizumab within 6 months or 5 half-lives before Visit 1 (whichever is longer).

9. Treatment with any investigational drug within 30 days or 5 half-lives (whichever is longer) prior to Visit 1.

10. Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to Visit 1.

11. Any laboratory abnormality or suspicion of any clinically relevant disease or disorder (on history or examination), including uncontrolled hypertension or uncontrolled diabetes, which, in the opinion of the Investigator, may either put the patient at risk because of participation in the study, or influence the results or the patient's ability to participate in the study, or any other safety concerns in the opinion of the Investigator.

12. Known chronic hepatitis or HIV infections at the time of enrolment.

13. Any active malignancy or treatment thereof within the 3 years prior to enrolment.

19. Unstable angina pectoris or stable angina pectoris classified higher than Canadian Cardiovascular Society Class II, or a myocardial infarction, or stroke within 6 months before Visit 1.

20. History of hospitalisation within 12 months caused by heart failure or a diagnosis of heart failure higher than New York Heart Association Class II.
