Researchers are evaluating the effectiveness and safety of a combination inhaler containing fluticasone propionate and albuterol sulfate, delivered via a multidose dry powder inhaler with an electronic module, in participants aged 12 years and older with asthma. This Phase 3 trial aims to compare this combination treatment to fluticasone propionate alone, albuterol sulfate alone, or a placebo inhaler. The study also assesses different dosing schedules, safety, tolerability, and pharmacokinetics of these inhalers. Participants will be randomly assigned to one of four groups receiving either the combination inhaler, fluticasone propionate inhaler, albuterol sulfate inhaler, or placebo, all with integrated electronic modules. Treatments are administered over a 4-week period with dosing four times daily. Pharmacokinetic assessments will be conducted after a single dose administration. The study is double-blind and placebo-controlled, with a parallel group design. Throughout the approximately 10-week study period, including screening and treatment, participants will undergo evaluations including lung function tests measuring forced expiratory volume in one second FEV1, asthma control questionnaires, and safety assessments. Researchers will monitor treatment-emergent adverse events and measure blood concentrations of the inhaled drugs. The study includes electronic monitoring of inhaler use and collects data at baseline, during treatment, and at week 4, with follow-up to assess efficacy and safety.
