E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to compare the clinical efficacy of twice daily, orally administrated AZD1981 with that of placebo over a 4-week treatment period in adults with persistent asthma. |
|
E.2.2 | Secondary objectives of the trial |
A secondary objective of the study is to evaluate the safety and tolerability. Other secondary objectives are pharmacokinetics, exploratory pharmacodynamics, and pharmacogenetics of AZD1981 given at repeated oral doses. |

E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
1. Provision of ICF (Informed Consent Form) could be obtained at an information visit prior to Visit 1 or at Visit 1 (according to local regulations), but before any study related procedures has been performed. 2. Men and post menopausal or surgically sterilized women, aged 18-60 years. Women will be considered post menopausal if they have been amenorrheic for at least 12 months, and an FSH plasma concentration within the post menopausal range as defined by the laboratory. 3. Minimum of 6 month’s documented history of asthma according to the ATS definition (ATS 1987). 4. Daily use of ≤400 µg inhaled GCS during 30 days prior to Visit 1. 5. FEV1 ≥60 - <100% of predicted normal value pre-bronchodilator. 6. Reversible airway obstruction either according to the reversibility test performed at Visit 1, or as historic data found in medical record (not older than 2 years) Reversibility is defined as an increase in FEV1 of ≥12% relative baseline and ≥200 mL after an inhalation of in total 1 mg Bricanyl Turbuhaler. If not fulfilled at Visit 1, criterion No 11 should be fulfilled at Visit 2. 7. The patient must not have had a clinically important asthma exacerbation, as judged by the investigator, one month before Visit 1. 8. A positive skin prick test to airway allergens (at least one) such as: pollen from birch, grass, or mugwort, animal fur for example dog, cat, horse, or house dust mite at Visit 1 or as historic data found in medical records not older than 2 years. 9. Able to read and write and use electronic devices. 10. Use of as-needed medication at least 4 times during the last week of the run-in period. 11. If the reversibility criterion is not met at Visit 1 (either from historic data or from the spirometry measurement) the patient must either show an increase in FEV1 of ≥12% relative baseline and ≥200 mL after an inhalation of in total 1 mg Bricanyl Turbuhaler or show a variation in PEF of at least 20% on at least 2 days during the run-in period. This should be calculated as follows: (max PEF - min PEF) / max PEF (all values from the same day). 12. The patient must not have taken more than 12 inhalations of as-needed medication on any single day during the run-in period. 13. The patient must not have had a clinically important asthma exacerbation, as judged by the investigator, during the run-in period. 14. Patients must not have used 8 inhalations or more of as-needed medication/24 hours on more than 2 days/week (any 7 days period) during the run-in period. 15. The patient must not have used iGCS during the run-in period. 16. No clinical relevant abnormal findings in clinical chemistry, haematology, FSH (females only), urinalysis, which, in the opinion of the investigator, may put patient at risk because of his/her participation in the study. 17. Provision of informed consent for pharmacogenetic research |
|
E.4 | Principal exclusion criteria |
1. Inability to tolerate withdrawal of asthma therapy as required for the study. 2. Hospitalisation for asthma within the last 2 years prior to Visit 1. 3. Respiratory infection significantly affecting the asthma, as judged by the investigator, within 30 days prior to Visit 1. 4. Any of the following: - current smoker, - patient with a history of smoking for more than 10 pack years (one pack year= 1 pack (20 cigarettes) per day for 1 year or equivalent), - ex-smoker since less than 1 year. 5. Body Mass Index (BMI) <18 kg/m 2 and body weight <50 kg. 6. A history of additional risk factors for Torsade de pointes (eg, heart failure, hypokalemia, family history of Long QT syndrome). 7. Use of concomitant medications that prolong the QT/QTc interval other than terbutaline or albuterol. 8. Use of β -blocker medication (including eye-drops) 9. Pregnancy or breast feeding. 10. Any significant disorder (eg, cardiovascular, pulmonary (other than asthma), gastrointestinal, hepatic, renal, neurological, musculosceletal, infectious, endocrine, metabolic, malignant, psychiatric, major physical impairment) which, in the opinion of the investigator, either put the patient at risk because of participating in the study or may influence the results of the study, or the patients ability to participate in the study. 11. Any clinical relevant abnormal findings in physical examination, pulse, blood pressure or ECG at Visit 1, which, in the opinion of the investigator, may put patient at risk because of his/her participation in the study. 12. Previous randomisation of treatment into the present study, see Section 3.5. 13. Planned hospitalisation during the course of the study. 14. Suspected poor capability to follow instructions of the study, as judged by the investigator. 15. Past or present alcohol or drug abuse. 16. Involvement in the planning and conduct of the study (applies to both AstraZeneca staff and staff at the study site). 17. Patients currently on immunotherapy, or who have had a course within the last 2 years. 18. Participation in another clinical study involving an investigational product within 3 months before Visit 1. |
