A Randomized, Double-blind, Multicenter, Parallel-group, Phase IIIb 52 Week Study Evaluating the Efficacy and Safety of PT027 Compared With PT007 Administered as Needed in Participants 12 to < 18 Years of Age With Asthma (ACADIA)
A Randomized, Double-blind, Multicenter, Parallel-group, Phase IIIb 52 Week Study Evaluating the Efficacy and Safety of PT027 Compared With PT007 Administered as Needed in Participants 12 to < 18 Years of Age With Asthma (ACADIA)
The purpose of this study is to compare the effect of budesonide/albuterol metered-dose inhaler (BDA MDI) with albuterol sulfate metered-dose inhaler (AS MDI), both administered as needed, on the annualized rate of severe asthma exacerbations in adolescents with a documented clinical diagnosis of asthma and at least one severe exacerbation in the prior year.
This is a randomized, double-blind, multicenter, parallel-group Phase IIIb study with a fixed treatment period of 52 weeks.
The study will consist of 3 periods:
Participants who meet the eligibility criteria will be randomly assigned to BDA MDI 160/180 micrograms (μg) or AS MDI 180 μg treatment groups in a 1:1 ratio on top of their own usual maintenance therapy during treatment period.
This study will also include a pharmacokinetic (PK) sub-study with single visit scheduled after the safety follow-up visit in the main study. During PK sub-study, single dose of open-label BDA MDI 160/180 μg will be administered.
Inclusion Criteria:
Confirmed clinical diagnosis of asthma at least 12 months.
Receiving one of the following scheduled asthma maintenance therapies for at least 3 months with stable dosing for at least the last one month
Receiving inhaled short-acting β2-agonist (SABA) as needed.
A documented history of at least one severe asthma exacerbation within 12 months.
Use of Sponsor-provided albuterol sulfate inhalation aerosol medication.
Demonstrate acceptable MDI administration technique as assessed by the investigator; use of spacers is prohibited.
Able to perform acceptable and reproducible peak expiratory flow (PEF) measurements as assessed by the investigator.
Participants must adhere to protocol specific contraception methods.
Negative urine pregnancy test for participants of childbearing potential.
Have a BMI < 40 kg/ m^2.
Capable of giving assent (signing the assent form) to participate in the study which includes compliance with the requirements and restrictions. The caregiver of the patient must be capable of giving written informed consent for the patient's participation in the study. Consent and assent forms must be completed prior to any study-specific procedures.
