An Open Label Placebo Study to Assess the Inhalation Profile in Asthmatic Patients Using the Nexthaler® Dry Powder Inhaler (DPI) Device (NEXThalerPIF)
Phase IIa, single-centre, open-label, single-arm study, to evaluate the inspiration profile through the NEXThaler® device in adult asthmatic patients with varying degrees of disease control.
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
- Evaluation of inhalatory profile for 40 patients [ Time Frame: One visit per patient (visit 1) ] [ Designated as safety issue: No ]The study duration per patient is only one visit. At visit 1 the patient after having signed off the ICF and after having assessed the Eligibility Criteria should perform two evaluable inhalatory manoeuvres. Each manoeuvre lasts few seconds. After having completed the manoeuvres and have the same assessed as good by the Investigator, the study is completed. All the procedures are expected to be performed within a couple of hours for each patient.

Inhalation of Placebo Dry Powder
Each patient will perform at least two inhalations using the Chiesi NEXThaler DPI device containing placebo dry powder. There is no comparator and all patients will receive the same study treatment.
Device: Inhalation through Chiesi NEXThaler DPI
Inhalatory manoeuvre through Chiesi NEXThaler DPI repeated at least twice in order to have two evaluable data set
The primary objective of this study is to assess the inspiratory flow profile through the NEXThaler® device in adult asthmatics with varying degrees of disease control.
The study plan foresees one visit at clinic. At Visit 1, after the signature of the informed consent form, the inclusion/exclusion criteria will be checked and the lung function parameters will be evaluated. If the subjects meet the inclusion/exclusion criteria, they will be instructed to use the NEXThaler®. The patients will subsequently inhale through the device and the inspiration profile will be measured.
A total of 40 asthmatic adults (≥18 years), 20 with controlled stable disease and 20 with partly controlled or uncontrolled disease according to GINA guidelines (2011), will be enrolled.
