A Long-term, Randomized, Double-blind, Multicenter, Parallel-group, Phase III Study Evaluating the Efficacy and Safety of PT027 Compared to PT007 Administered as Needed in Response to Symptoms in Symptomatic Adults and Children 4 Years of Age or Older With Asthma
A Long-term, Randomized, Double-blind, Multicenter, Parallel-group, Phase III Study Evaluating the Efficacy and Safety of PT027 Compared to PT007 Administered as Needed in Response to Symptoms in Symptomatic Adults and Children 4 Years of Age or Older With Asthma
This is a randomized, double-blind, multicenter, parallel-group, variable-length study to compare 2 doses of BDA MDI (PT027) with AS MDI (PT007) on the time to first severe asthma exacerbation in adult, adolescent, and pediatric subjects with moderate to severe asthma.
Inclusion Criteria:
Female or male aged ≥4 years at the time of informed consent
Physician diagnosis of asthma documented for at least 1 year
Receiving 1 of the following scheduled asthma maintenance therapies for 3 months with stable dosing for at least the last 4 weeks before Visit 1:
Prebronchodilator forced expiratory volume in 1 second (FEV1) of ≥40 to <90% predicted normal value for adults and adolescents, and ≥60 to <100% predicted normal value for subjects aged 4 to 11 years after withholding specified medications including short/rapid-acting β2-adrenoreceptor agonist (SABA)
Demonstrate reversibility at Visit 1, with an increase in FEV1 ≥12% (and ≥200 mL for subjects aged ≥18 years) relative to baseline after administration of sponsor provided Ventolin via central spirometry. One re-test for reversibility testing is allowed within the screening period in advance of Visit 2
Demonstrate acceptable spirometry performance (i.e., meet American Thoracic Society/European Respiratory Society acceptability/repeatability criteria)
A documented history of at least 1 severe asthma exacerbation within 12 months before Visit 1
Able to perform acceptable and reproducible peak expiratory flow (PEF) measurements as assessed by the investigator
