|
E.2.2 | Secondary objectives of the trial |
- To assess the effect of CHF 6532 on severe asthma exacerbations compared to Placebo over 52 weeks of treatment.
- To assess the effect of CHF 6532 compared to Placebo in terms of change from baseline in pre-dose morning forced expiratory volume in the first second (FEV1) at Week 52.
- To perform a population PK analysis investigating the inter-subject variability in the drug exposure and the effect of selected covariates on PK.
- To assess the effect of CHF 6532 compared to Placebo in terms of change from baseline on SGRQ, ACQ-5, AQLQ+12, at Week 52.
- To collect data in order to assess the impact of study treatments on health economics outcome.
- To assess the safety and the tolerability of the study treatments with respect to adverse events, electrocardiograms (ECGs), Vital Signs and Laboratory tests. |

-to perform all trial related procedures including technically acceptable pulmonary function tests;
-to correctly use the electronic diary/peak flow meter.

4.Subjects with a history of near fatal asthma or of a past hospitalisation for asthma in intensive care unit which, in the judgement of the investigator, may place the subjects at undue risk.
5.Bacterial lower respiratory tract infection: Subjects with a history of more than 2 episodes of confirmed bacterial lower respiratory tract infection within the year prior to screening or with a bacterial lower respiratory tract infection during the run-in.
6. History of diagnosis of COPD, cystic fibrosis, bronchiectasis or alpha-1 antitrypsin deficiency, or any other significant lung disease which may interfere with study evaluations.

10.Subjects who have known clinically significant cardiovascular conditions
11.Subjects with a history of symptoms or significant neurological disease
12.Subjects with clinically significant abnormal serum biochemistry, haematology (not associated with the study indication) at screening according to the investigators judgement.

14.Subjects with historical or current evidence of uncontrolled concurrent disease
15.Subjects with a history of hypersensitivity and/or idiosyncrasy to any of the test compounds or excipients employed in this study.

20.Subjects with ALT or AST at screening ≥2xULN.
21.Subjects with other severe acute or chronic medical or malignancy or psychiatric conditions which are uncontrolled or laboratory abnormality that may increase the risk associated with study participation or study drug administration or may interfere with the interpretation of study results and would make the subjects inappropriate for entry into this study.
22.Subjects with a history of lung volume resection.
23.Lung cancer or history of lung cancer: Subjects with a diagnosis of lung cancer or a history of lung cancer.
24.Cancer or history of cancer (other than lung): Subjects with active cancer or a history of cancer with less than 5 years disease free survival time (whether or not there is evidence of local recurrence or metastases). Localised carcinoma (e.g. basal cell carcinoma, in situ carcinoma of the cervix adequately treated) is acceptable.
25.Participation to investigational trial: Subjects who have received an investigational drug within 30 days (60 days for biologics) or five half-lives (whichever is greater) prior to screening visit.
