Comparing two types of nebulizer solutions for COPD patients

A Randomized, Parallel Group, Phase III, Non-inferiority Study Comparing Ipratropium / Levosalbutamol Fixed Dose Combination and Ipratropium and Levosalbutamol Free Dose Combination Nebuliser Solutions in Stable Chronic Obstructive Pulmonary Disease (COPD)

Phase 3 Interventional Neutec Ar-Ge San ve Tic A.Ş · NCT05890638

This study is testing which type of nebulizer solution works better for helping people with COPD breathe easier, using a fixed dose versus a free dose of two common medications.

What this trial studies

This clinical trial aims to evaluate the effectiveness of a fixed dose combination of Ipratropium and Levosalbutamol versus a free dose combination of the same medications in patients with stable moderate to very severe Chronic Obstructive Pulmonary Disease (COPD). Participants will be assessed based on their lung function and symptom severity using standardized scales. The study will involve patients aged 40 and older who meet specific criteria related to their COPD diagnosis and smoking history. The goal is to determine which nebulizer solution provides better acute bronchodilator effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 and older with stable moderate to very severe COPD and specific lung function measurements.

Not a fit: Patients with mild COPD or those who have experienced an exacerbation in the past four weeks may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with COPD, enhancing their breathing and overall quality of life.

How similar studies have performed: Previous studies have shown varying results with similar approaches, but this specific comparison is novel.

* Recent (within ≤3 months prior the screening visit) history of heart attack, heart failure, acute ischemic heart disease or presence of serious cardiac arrhythmia requiring drug treatment.
* Regularly use of daytime CPAP (continuous positive airway pressure) oxygen therapy for longer than 1 hour per day.
* Initiation of pulmonary rehabilitation within the 3 months prior the screening visit.
* History of lung volume reduction surgery
* Drug or alcohol abuse
