Escalating and Cumulative-Dose Study of Pharmacokinetics (PK), Pharmacodynamics (PD) and Safety of A006

Completed · Phase 2 · Has a placebo group

Conditions studied: Asthma, Bronchospasm, Chronic Obstructive Pulmonary Disease (COPD)

In brief

The main objective is to evaluate the bronchodilatory efficacy, safety and pharmacokinetic profiles of A006 (Albuterol Dry Powder Inhaler (DPI)), in comparison with those of an active control, Proventil-HFA (Albuterol Metered Dose Inhaler (MDI)), and a Placebo DPI in escalating and cumulative-doses up to 1440 mcg, eight (8) times of the proposed clinical dose.
