Efficacy and Safety of PT001 to Placebo and Open-label Spiriva® Respimat® in Subjects With Persistant Asthma

Change from baseline in forced expiratory volume in 1 second (FEV1) area under the curve from 0 to 4 hours (AUC0-4)AUC was normalized for length of follow up (e.g. typically 4 hours).

Rate of moderate to severe Asthma exacerbations (A deterioration of asthma requiring a new or increased dose of ICS for at least 3 days) or severe Asthma exacerbation (Use of systemic corticosteroids (tablets, suspension, or injection) for at least 3 days OR a hospitalization or ER visit because of asthma)

ACQ-7: The ACQ, comprising 7 questions, is completed in the clinic and requires subjects to recall their experiences during the previous week (7 days) prior to the study visit. The ACQ-5 measures 5 symptoms (woken at night by symptoms, wake in the morning with symptoms, limitation of daily activities, shortness of breath, and wheeze); the ACQ-6 is these symptom measurements plus daily rescue medication use as recalled by the subject; and the ACQ 7 is the ACQ 6 plus airway caliber as measured by pre-bronchodilator FEV1 percent predicted. Each question is scored on a 7-point scale (generally, 0=no impairment, 6=maximum impairment), the questions are equally weighted, and the ACQ score is the mean of the item responses and therefore ranges from 0 (totally controlled) to 6 (severely uncontrolled.

AQLQ +12 - Asthma Quality of Life Questionnaire The AQLQ +12 is a 32-item validated subject-administered questionnaire that was developed to measure the functional problems (physical, emotional, social and occupational) that are most troublesome to adults (≥18 years of age) and adolescents (12 to 17 years of age) with asthma. The 32 questions in the AQLQ +12 are in 4 domains (symptoms, activity limitation, emotional function, and environmental stimuli). All 4 domains contain standard specific questions relating to each domain. Subjects are asked to think about how they have been during the previous 2 weeks. Responses to each of the 32 questions are on a 7-point scale (7=no impairment to 1=severe impairment). The overall AQLQ +12 score is the mean of all 32 responses. Overall scores range from 1=severe impairment to 7=no impairment.
