Researchers are evaluating the safety and effectiveness of tezepelumab in children aged 5 to under 12 years who have severe uncontrolled asthma. These children must be on medium to high doses of inhaled corticosteroids along with at least one other asthma controller medication, with or without oral corticosteroids. This phase 3, multicenter, double-blind, placebo-controlled study aims to better understand how tezepelumab affects asthma control in this pediatric population. Participants will be randomly assigned in a 2:1 ratio to receive either subcutaneous injections of tezepelumab or a matching placebo for 52 weeks during the double-blind treatment period. Before this, there is a 4 to 6 week screening and run-in phase. After the treatment period, a 12-week follow-up phase occurs without treatment. Eligible participants can then join an optional open-label extension, receiving tezepelumab for an additional 104 weeks followed by another 12-week post-treatment follow-up. Throughout the study, participants will have regular assessments including lung function tests, asthma control questionnaires, and monitoring for asthma exacerbations. Researchers will measure the annualized rate of severe asthma flare-ups from the start of treatment to week 52. Safety and treatment adherence will also be closely monitored during all study phases, with total participation potentially extending over two years for those in the extension period.

This research aims to evaluate the effectiveness and safety of a fixed-dose combination of fluticasone propionate (Fp) and albuterol sulfate (ABS) delivered via an integrated electronic module multidose dry powder inhaler (eMDPI) compared to ABS alone in reducing severe clinical asthma exacerbations in patients with asthma. The study also assesses the efficacy of a low dose of Fp/ABS versus ABS and examines the impact on systemic corticosteroid exposure. This is a phase 3 randomized, double-blind, active-controlled trial involving patients diagnosed with asthma for at least one year. Participants will receive either a high dose or low dose of Fp/ABS or ABS alone through oral inhalation powder during a double-blind treatment period lasting a minimum of 24 weeks. The study includes a 2-week screening phase, a 2 to 4-week run-in period, and the treatment phase. Because this is an event-driven study, the total duration for individual participants may extend up to approximately 42 months depending on enrollment timing and study completion. During the study, participants will be closely monitored for time to first severe clinical asthma exacerbation while using the inhaler device. Safety and tolerability will be evaluated throughout the study. Researchers will also track systemic corticosteroid use and overall asthma control. The minimum participation time is 28 weeks, including screening and run-in, with extended monitoring possible based on study events and criteria.

Researchers are evaluating the effects of two inhalers, budesonide/albuterol metered-dose inhaler (BDA MDI) and albuterol sulfate metered-dose inhaler (AS MDI), both taken as needed, on reducing severe asthma attacks in adolescents aged 12 to under 18 years who have a clinical diagnosis of asthma and have experienced at least one severe asthma exacerbation in the past year. This is a Phase IIIb randomized, double-blind, multicenter study lasting 52 weeks with a safety follow-up period after treatment. Participants will be randomly assigned to receive either BDA MDI 160/180 micrograms (two puffs of 80/90 micrograms) or AS MDI 180 micrograms (two puffs of 90 micrograms) as needed, alongside their usual asthma maintenance therapy, for 52 weeks. The study includes a 7 to 28-day screening period before treatment and a safety follow-up visit 7 to 14 days after the end of treatment. Additionally, a pharmacokinetic sub-study involves a single dose of open-label BDA MDI administered after the safety follow-up. During the study, participants will be monitored for the annual rate of severe asthma exacerbations from randomization to week 52. Assessments include evaluating inhaler technique, peak expiratory flow measurements, and adherence to contraception methods for participants of childbearing potential. Safety will be monitored throughout the treatment and follow-up periods. The total study duration includes screening, 52 weeks of treatment, and safety follow-up.
