A Randomized, Placebo-controlled, Parallel Group Study Designed to Assess the Change in Mucociliary Clearance After 12 Weeks of Treatment With Dupilumab in Patients With Moderate to Severe Asthma
Single center, randomized, placebo- controlled study to assess change in mucociliary clearance of moderate to severe asthma patients after treatment with dupilumab or placebo.
• Moderate - Severe Th2 (Type 2) High asthma, as defined by Forced Expiratory Volume in one second (FEV1) \<90% predicted, on medium to high dose inhaled corticosteroids (ICS) with or without a second controller
• Age \> 18
• Inhaled steroid doses of 500micrograms (mcg) per day or more (Fluticasone equivalent)
• Reversibility \>/= 12% at screening or within the past 2 years, or a positive methacholine challenge test within the past 2 years, or a positive methacholine challenge during screening
• FEV1/Forced Vital Capacity (FVC)\<75%
• Blood Eosinophils (EOS) \>300 cells per mm3
• Exhaled Nitric Oxide (FeNO) \>25 parts per billion (ppb)
• Asthma Control Test (ACT) score \<20
