New triple inhaler could help teens with Hard-to-Control asthma
NCT ID NCT05757102
First seen Jun 26, 2026 · Last updated Sep 10, 2026 · Updated 5 times
Summary
This study tests whether a triple-combination inhaler (containing three drugs) works better than a standard dual-combination inhaler for teenagers aged 12-17 whose asthma is not well controlled. About 292 participants will use either the triple or dual inhaler daily for 24 weeks. The main goal is to see if the triple inhaler improves lung function more than the dual one.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fluticasone furoate, umeclidinium, and vilanterol (a triple-combination inhaler)
- What this could lead to
- If it works, this could offer a more effective daily inhaler option for teenagers whose asthma is not well controlled with current two-drug inhalers.
- What could go wrong
- This is a relatively small, short-term study (24 weeks) in a specific age group. The triple inhaler may not prove significantly better than the standard dual inhaler, and long-term safety in teens is not yet established.

Inclusion Criteria: * Participant must be 12 to 17 years of age (inclusive), at the time of signing the informed consent/assent. * Participants who have a diagnosis of asthma as defined by the National Institutes of Health \[NIH, 2020\] at least 1 year prior to Visit 0. * Participants who have required daily Inhaled corticosteroids (ICS)/ Long-Acting Beta2-Agonist (LABA) treatment for at least 12 weeks prior to Visit 0 with no changes to maintenance asthma medications during the 6 weeks immediately prior to Visit 0 (including no changes to a stable total ICS dose of \>250 to \<=500 microgram (mcg)/day fluticasone propionate, or equivalent). * In the 1 year prior to Visit 1: A documented healthcare contact for acute asthma symptoms; OR A documented temporary change in asthma therapy for acute asthma symptoms, according to a prespecified asthma action plan (or equivalent). * Participants with inadequately controlled asthma (ACQ-6 score ≥1.5) at Visit 1, despite ICS/LABA maintenance therapy. * A best pre-bronchodilator FEV1 \>40% to \<=90% of the predicted normal value and a ≥12% increase in FEV1 with albuterol/salbutamol at Visit 1. Predicted values will be based on the European Respiratory Society (ERS) Global Lung Function Initiative. Exclusion Criteria: * Chest X-ray documented pneumonia in the 6 weeks prior to Visit 1. * Any asthma exacerbation requiring a change in maintenance asthma therapy and/or the use of systemic corticosteroids for at least 3 days in the 6 weeks prior to Visit 1. (Participants requiring a temporary change in asthma therapy (e.g., oral corticosteroids or increased dose of ICS) to treat an exacerbation in the 6 weeks prior to Visit 1 are not explicitly excluded at Visit 1 provided that, at the Investigator's discretion, the participant's condition is stable after they have resumed their pre-exacerbation maintenance asthma therapy (without modification), returned to their baseline asthma status and they are considered appropriate for enrollment into this study of up to 6 months duration) * History of Life-threatening Asthma * Participants with current evidence of active pulmonary diseases or abnormalities other than asthma (e.g., pneumonia, active tuberculosis, significant bronchiectasis, etc.). * Current smokers and users of other inhaled products for recreation with or without nicotine (defined as participants who use cigarettes, e-cigarettes, other/vaping-related devices, cigars or pipe tobacco\]) within 12 months prior to Visit 1.
