Effect of Spacer Use on Exacerbation Risk in High-Risk Older Adults With Chronic Airway Diseases Receiving Triple Therapy
Effect of Spacer Use on Exacerbation Risk in High-Risk Older Adults With Chronic Airway Diseases Receiving Triple Therapy: A Multicenter Randomized Controlled Trial
Source: ClinicalTrials.gov · Last updated 26 Jun 2026
Brief summary (registry, in English)
This study evaluates whether adding a spacer device to triple inhaled therapy (ICS/LABA/LAMA via pMDI) can reduce acute exacerbations in elderly patients (≥65 years) with stable chronic airway diseases (COPD or asthma) who are classified as high-risk based on GOLD or GINA guidelines. High risk is defined as ≥1 hospitalization or ≥2 moderate exacerbations in the past 12 months. Despite receiving triple inhaled therapy, these patients often have poor inhaler technique due to age-related limitations. A spacer may improve drug delivery, adherence, and reduce local side effects. In this multicenter, open-label, randomized controlled trial, 380 participants will be assigned to standard therapy with or without a valved spacer. The primary outcome is the 3-month incidence of moderate-to-severe exacerbations. Secondary outcomes include lung function, adherence, inhalation technique, side effects, and patient satisfaction.

- Presence of severe systemic comorbidities (e.g., end-stage malignancy, advanced heart failure, hepatic or renal failure);
- Known allergy or hypersensitivity to spacer device materials.
Other
- Current or recent (within 4 weeks) acute exacerbation not fully resolved;
- Participation in another interventional clinical trial;
- Inability to use a mouthpiece-based spacer (e.g., structural oral/facial abnormalities, severe anxiety);
Who the study is looking for
