Eligibility Criteria
Inclusion
- Able and willing to give written informed consent.
- Healthy male and female subjects, aged 18-65 years. Women will be considered for inclusion if they are:
- Not pregnant, as confirmed by pregnancy test (see flow chart), and not nursing. Of non-child bearing potential (i.e. physiologically incapable of becoming pregnant, including any female who is pre-menarchial or post-menopausal, with documented proof of hysterectomy or tubal ligation, or meets clinical criteria for menopause and has been amenorrhoeic for more than 1 year prior to the screening visit).
- Of childbearing potential and using a highly effective method of contraception during the entire study (vasectomised partner, sexual abstinence - the lifestyle of the female should be such that there is complete abstinence from intercourse from two weeks prior to the first dose of study medication until at least 72 hours after treatment -, implants, injectables, combined oral contraceptives, hormonal IUDs or double-barrier methods, i.e. any double combination of IUD, condom with spermicidal gel, diaphragm, sponge, and cervical cap).
- Body mass index between 18 and 32 kg/m2
- Normal lung function with FEV1 predicted ≥ 80% and FEV1/FVC ≥ 70% at screening V1 ( or performed within 12 months prior to the screening visit at Fraunhofer ITEM and no evidence of clinical relevant abnormal findings in the lung function in the previous year before screening in the anamnesis).
- Nonsmokers with a history of less than 1 pack year having been nonsmokers for at least the last 12 months
- Emission of acceptable quantities of exhaled particles at screening (\>200ng particle mass within 15 min)
Exclusion
- Any clinically relevant abnormal findings, which, in the opinion of the investigator, may either put the subject at risk because of participation in the study or may influence the results of the study, or the subject's ability to participate in the study
- Past or present disease, which as judged by the investigator, may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, hepatic disease, renal disease, hematological disease, neurological disease, endocrine disease or pulmonary disease (including but not confined to asthma, chronic bronchitis, emphysema, tuberculosis, bronchiectasis or cystic fibrosis).
- Regular intake of any prescribed or over the counter medication. Exceptions include paracetamol for pain relief, oral contraceptive medication, hormonal replacement therapy, dietary and vitamin supplements
- Clinically relevant history of allergy as judged by the investigator
- Intolerance or contraindications to salbutamol
- Infections of the lower respiratory tract within 4 weeks before visit 1, visit 2 or visit 3. These patients can be rescreened starting from visit 1.
- Participation in another clinical trial with an IMP 30 days or five half-lives, whichever is longer, prior to enrollment
- History of drug or alcohol abuse
- Risk of non-compliance with study procedures
- Suspected inability to understand the protocol requirements, instructions and study-related restrictions, the nature, scope, and possible consequences of the study
- Significant nasal deformity, recent nasal surgery or obstructing nasal polyps
