Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the effect of tralokinumab on eosinophilic airway infiltration in adult subjects with asthma inadequately controlled with ICS.;Primary end point(s): The change, expressed as a ratio, in number of airway submucosal eosinophils per mm2 determined by microscopic evaluation of bronchoscopic biopsies from baseline up to week 12.;Timepoint(s) of evaluation of this end point: Week 12; Secondary Objective: To evaluate the effect of tralokinumab on blood eosinophil levels in adult subjects with asthma inadeuately controlled with ICS. To evaluate the effect of tralokinumab on activation of eosinophils in adult subjects with asthma inadequately controlled with ICS.

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: Week 12; Secondary end point(s): 1. The change, expressed as a ratio, in number of blood eosinophils from baseline up to week 12. 2. The change, expressed as a ratio, in the number of differential sputum eosinophils from baseline up to week 12. 3. The change,expressed as a ratio, in blood and sputum free eosinophil cationic protein (ECP) concentrations from baseline up to week 12.
