Study Endpoints

Primary Endpoints

Change from baseline in pre-bronchodilator FEV1 at Week 16
up to Week 16

FEV1 is the Forced expiratory volume in one second at study site

Number of Participants With Eczema Area and Severity Index (EASI) - 75 Response (>= 75% Improvement in Score From Baseline) at Week 16
Baseline, Week 16

The EASI score was used to measure the severity and extent of atopic dermatitis (AD) and measures erythema, infiltration, excoriation and lichenification on 4 anatomic regions of the body: head, trunk, upper and lower extremities. The total EASI score range from 0 (minimum) to 72 (maximum) points, with the higher scores reflecting the worse severity of AD.

Secondary Endpoints

Change from baseline in Chronic Obstructive Pulmonary Disease assessment tool (CAT) score
up to Week 16
Change from baseline in St. George's Respiratory Questionnaire (SGRQ) total score
up to Week 16
Percentage of participants with a decrease in SGRQ total score of ≥ 4 points from baseline to Week 16
