Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to simulate the deposition of aerosol drugs within the airways of asthma and COPD patients based on realistic breathing patterns measured at different pulmonology centers.

Further goal of the study is to find correlations between the amount of drug depositing in the lungs and the measured breathing parameters, as well as disease status and demographic data. The results of the study will be part of a major objective targeting the optimization and personalization of aerosol drug therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The inhalation of aerosol drugs is a key element of current asthma and COPD treatment. The efficiency of the therapy is highly influenced by the dose depositing in the lungs. However, the amount of drug depositing in the lung is a result of complex drug particle-inhaler-patient interaction, thus it is inhaler-, drug- and patient-specific. Assuming that the airflow dependent aerodynamic characteristics of the drugs are known, the lung dose depends on the patient's breathing parameters during the inhalation of drug through the inhaler. In this study the inhalation parameters of asthmatic and COPD patients are measured and lung deposition assessed by a validated numerical lung deposition model. Effects of different breathing parameters (inhalation time, inhaled volume, average flow rate, peak flow rate, time until peak flow rate is reached, breath-hold time) as well as patient demographic data, disease type and disease severity on the lung dose are studied. The correlations are analysed for asthma and COPD groups separately.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Asthma patients

Patients with proven record of asthma disease.

Emptied dry powder inhalers (DPI) used in routine asthma and COPD therapy

Intervention Type DEVICE

The DPI inhaler devices are empty, without any active ingredient or/and carrier substances. Patients are not inhaling drug doses because of the study. They are inhaling only the type and quantity of aerosol drugs that they would inhale because of their treatment. The study does not influences the undergoing treatment by medication in any way.

COPD patients

Patients with proven record of COPD disease.

Emptied dry powder inhalers (DPI) used in routine asthma and COPD therapy

Intervention Type DEVICE

The DPI inhaler devices are empty, without any active ingredient or/and carrier substances. Patients are not inhaling drug doses because of the study. They are inhaling only the type and quantity of aerosol drugs that they would inhale because of their treatment. The study does not influences the undergoing treatment by medication in any way.
