E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
PURPOSE
The purpose of this study is to better understand the mechanistic effects of Azithromycin (AZM) in asthma, and to establish if AZM therapy is effective in a subgroup of patients with chronic asthma who have phenotypically distinct disease
PRIMARY OBJECTIVE
• To study the effects of AZM in well phenotyped patients with asthma.
|
|
E.2.2 | Secondary objectives of the trial |
• To determine if the clinical response to AZM therapy relates to the underlying asthma phenotype(individually distinct characteristics), including presence or absence of bacterial infection, or inflammatory subtype (eosinophilic vs. neutrophilic).
• To ascertain whether the in vitro response of human bronchial epithelia cells to AZM predicts the clinical response and provide a greater insight into the mechanism of action of this compound.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Asthmatics
