   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. Female patients 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)

   Additional Inclusion criteria for Healthy /volunteers and Asthmatic patients:

9. Males and females aged 18-55

10. Non- or Ex-smokers who smoked < 5 pack years (pack-years = number of cigarette packs per day times the number of years) and stopped smoking > 1 year

    Additional Inclusion Criteria only for Healthy volunteers:

11. Lung function within normal limits: FEV1 ≥ 80% of predicted (according to the Global Lung Function Initiative, ERS Task Force Lung Function Reference Vales) and FEV1/FVC ratio > 0.70 at screening

    Additional Inclusion Criteria only for Asthmatic patients:

12. Pre-bronchodilator 60% ≤ FEV1 ≤ 80% of predicted (according to the Global Lung Function Initiative, ERS Task Force Lung Function Reference Vales) and FEV1/FVC ratio > 0.70 at screening. If this criterion is not met at Screening, the test can be repeated once before Day -1.

13. Positive reversibility test as defined by an increase in FEV1 ≥ 12% and at least 200 ml compared to the initial value 20-30 minutes after inhalation of 400 μg Salbutamol at screening. If this criterion is not met at Screening, the test can be repeated once before Day -1.

    Additional Inclusion Criteria only for COPD patients:

14. Males and females aged 40-75

15. Current or ex- smokers (stopped smoking > 1 year ) minimum smoking history of 10 pack-years (packyears = number of cigarette packs per day times the number of years)

16. 30% ≤ FEV1 < 50% of predicted and FEV1/FVC < 0.70 after inhalation of 400 μg Salbutamol. If this criterion is not met at Screening, the test can be repeated once before Day -1.

Exclusion Criteria for all subjects:

1. Pregnant or lactating women

2. Documented history of drug abuse (within 12 months before screening) and/or positive urine drug test at screening and/or at treatment period

3. History of hypersensitivity to M3 Antagonists, β2-agonist, corticosteroids or any of the excipients contained in any of the formulations used in the trial;
