Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to evaluate the efficacy, dose-ranging and initial safety profiles of A006, an Albuterol dry powder inhaler (DPI), in the dose range of 25 to 180 mcg per dosing in comparison to a DPI Placebo Control and an Albuterol metered dose inhaler (MDI) Active Control.

This study will be conducted in male and female adult patients who have mild-to-moderate persistent asthma for at least 6 months, but are otherwise generally healthy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main objective of this study is to evaluate the efficacy, dose-ranging and initial safety profiles of A006, an Albuterol dry powder inhaler (DPI), in the dose range of 25 to 180 mcg per dose in comparison to the DPI Placebo Control and the Active (Reference) Control. The study results of this study together with that of A006-B study will be utilized to determine the optimum final dose range of A006 for further clinical studies.

The study will be conducted in male and female adult patients who have mild-to-moderate persistent asthma but are otherwise generally healthy.

* With mild-to-moderate persistent asthma for at least 6 months prior to screening and having used a beta-agonist(s) inhaler
* Demonstrate a Forced Expiratory Volume (FEV1) at 50-85 percent of predicted normal during screening baseline measurement
* Demonstrate an airway reversibility of greater than or equal to 15 percent within 30 minutes of inhaling 2 inhalations of Proventil MDI during screening visit
* Demonstrate Peak Inspiratory Flow Rate (PIF) within 80-150 L/min (after training), at least 2 times consecutively
* Demonstrate ability to use a DPI and MDI inhaler properly after training

* Properly agree to participate in the trial

Exclusion Criteria

* A smoking history of more than or equal to 10 years or having smoked within 6 months of screening visit
* Upper respiratory tract infections within 2 weeks or lower respiratory tract infection within 4 weeks prior to screening visit
* Asthma exacerbations that required emergency care or a hospital stay within 4 weeks prior to screening visit
* Any current or recent respiratory tract infections that might affect the response to the study drug as determined by the investigator, including cystic fibrosis, bronchiectasis, tuberculosis, emphysema and other significant respiratory diseases besides asthma
* Current clinically significant cardiovascular, hematological, renal, neurologic, hepatic, endocrine, psychiatric, malignant or other illnesses that could impact the study as determined by the investigator
