   1. Males with non-pregnant Women of childbearing potential (WOCBP) partners: they and/or their partner of childbearing potential must be willing to use a highly effective birth control method in addition to the male condom from the signature of the informed consent and until 90 days after the follow-up visit. Subjects must not donate sperm during the study and for 90 days after the follow-up visit or
   2. Males with pregnant WOCBP partner: they must be willing to use male contraception (condom) from the signature of the informed consent and until 90 days after the follow-up visit. Subjects must not donate sperm during the study and for 90 days after the follow-up visit or

   1. WOCBP with fertile male partners: they and/or their partner must be willing to use a highly effective birth control method with low user dependency from the signature of the informed consent and until 30 days after the follow-up visit or
   2. WOCBP with non-fertile male partners (contraception is not required in this case).
8. Females of non-childbearing potential defined as physiologically incapable of becoming pregnant (i.e. post-menopausal or permanently sterile). Tubal ligation or partial surgical interventions are not acceptable. If indicated, as per investigator's request, post-menopausal status may be confirmed by follicle-stimulating hormone levels (according to local laboratory ranges)
9. 12 -lead digitised Electrocardiogram (12-lead ECG) considered as normal at screening and at Day -1

Additional Criteria only for Healthy Volunteers and Asthmatic patients:

1. Male and female subjects aged 28-55 years inclusive;
2. Non- or ex-smokers who smoked \< 5 pack years (pack-years = the number of cigarette packs per day times the number of years) and stopped smoking \> 6 months prior to screening;

Additional Inclusion Criteria only for Healthy Volunteers:

1. Lung function measurements within normal limits at screening: FEV1 equal to or more than 80% of predicted

Additional Inclusion Criteria only for Asthmatic patients:

1. Diagnosis of asthma: Established diagnosis of permanent asthma for at least 12 months according to GINA guidelines
2. Patients with a pre-bronchodilator 60%≤ FEV1 \< 80% of the predicted normal value
3. Patients with a documented reversibility defined as an increase ≥ 12% and 200mL over baseline within 30 min after inhalation of 400µg salbutamol pMDI

Additional Inclusion Criteria only for COPD patients:

1. Male and female patients aged 40-80 years inclusive
2. A smoking history of at least 10 pack-years
3. Current or ex-smokers are eligible.
4. Established diagnosis of COPD
5. A post-bronchodilator FEV1 ≤ 50% of the predicted normal value and a post-bronchodilator FEV1/FVC \< 0.7 10-15 minutes after 4 puffs (4x100 µg) of Salbutamol pMDI.
