Primary Outcome Measures
NameTimeMethod
Change From Baseline in Volume of Mucin Per Surface Area of Basal LaminaAt baseline (visit 2) and at visit 5.

Change from baseline in volume of mucin per surface area of basal lamina. Volume of mucin per surface area of basal lamina (vs mu,bala) was determined by stereologic quantification of Periodic Acid Schiff's (AB/PAS) reagent staining in endobronchial biopsies at visit 2 (baseline) and at the end of the 4-week period of randomized treatment (visit 5).

Measurements visit 2 are used to standardize measurements at visit 5, and the standardized visit 5 value is calculated in percent (%) control as (visit5/visit2\*100).
