- •4. Body mass index (BMI) between 18 and 30 kg/m2 (inclusive)
- •5. Non-smoker or ex-smoker who has stopped smoking for >6 months before screening and have a smoking history of not more than 10 pack years
- •6. Diagnosed asthma for at least 6 months. Asthma is defined according to the global initiative for asthma (GINA), 2012
- •7. Pre-bronchodilator FEV1 =60% and =90% of predicted normal value and =1.5 L at screening
- •8. Increase in FEV1 of =15% within 30 minutes after a 2.5mg dose of nebulised salbutamol
- •9. Able to correctly use the study nebuliser
- •10. Able to complete the clinical study
- •11. Systolic blood pressure 90 to 145 mmHg, diastolic blood pressure 50 to 90 mmHg and heart rate 45 to 80 beats per minute (bpm) after resting for 5 minutes in a supine position (average from two measurements)
- •12. Patients must be capable of withdrawing from long acting ß2 agonists (LABAs) and long acting muscarinic antagonists (LAMAs) for 72 hours and short acting muscarinic antagonists (SAMAs) for 8 hours before the reversibility test at screening and expected to be able to withhold during study
- •13. Patients must be capable of withdrawing from short acting ß2 agonists (SABAs) for 8 hours before the reversibility test at screening and 8 hours before all study drug administrations
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 25

- •F.1.3.1 Number of subjects for this age range 5
排除标准
- •1. Asthma exacerbation (defined as requiring medical intervention) in the 3 months before screening
- •2. Any prior life threatening episode of asthma (intensive care admission)
- •3. Any clinically significant disease or disorder (e.g. cardiovascular, pulmonary other than asthma, chronic obstructive pulmonary disease [COPD], gastrointestinal, liver, renal, neurological, musculoskeletal, endocrine, metabolic, malignant, psychiatric, major physical impairment) which, in the opinion of the Investigator, may either put the patient at risk because of participation in the study, or influence the result of the study, or the patient´s ability to participate in the study
- •4. Any clinically relevant abnormal findings in physical examination, clinical chemistry, haematology, urinalysis, vital signs, ECG or lung function at screening, which, in the opinion of the Investigator, may put the patient at risk because of his/her participation in the study
- •5. QTcF interval >450 ms or QT interval >500 ms or other abnormality in ECG making interpretation more difficult, as judged by the Investigator
- •6. History of ischemic heart disease or heart failure. History of recurrent or current clinically significant arrhythmia or ECG abnormality as judged by the investigator
- •7. Treatment with systemic glucocorticosteroids within 30 days before screening
- •8. A definite or suspected personal history of intolerance or hypersensitivity to drugs and/or their excipients, judged to be clinically relevant by the Investigator
- •9. Donation of blood within 1 month or donation of plasma within 14 days before screening
- •10. History of, or current alcohol or drug abuse, as judged by the Investigator
- •11. A suspected/manifested infection according to the World Health Organisation (WHO) risk classification 2, 3 or 4
