NCT05445349

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Lung deposition fraction

    Lung deposition fraction is the ratio of the drug dose depositing in the lungs to the dose available in the device. Lung dose will be evaluated by means of computer modelling based on input data (breathing parameters) measured in this study.

    July 1, 2023 - June 30, 2025

Secondary Outcomes (5)

  • Inhalation time

    August 1, 2022 - June 30, 2023

  • Peak inhalation flow

    August 1, 2022 - June 30, 2023

  • Inhaled volume

    August 1, 2022 - June 30, 2023

  • Ramp-up time

    August 1, 2022 - June 30, 2023

  • Breath-hold time

    August 1, 2022 - June 30, 2023

Study Arms (2)

Asthma patients

Patients with proven record of asthma disease.

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

COPD patients

Patients with proven record of COPD disease.

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

Interventions

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.

Sampling MethodProbability Sample
Study Population

We are recruiting participants for our test from different levels of healthcare servicing (university centre, regional institute, county hospital, panel clinic) aiming to minimize centre specific effects.

You may qualify if:

  • diagnosed obstructive lung disease (asthma or COPD)
  • proper usage of inhalation tool after being educated
  • availability of whole body plethysmography measurement data from the last 6 months or the possibility to perform them before the start of the study
  • subject under outpatient/inpatient therapy
  • capable of acting and cooperating

You may not qualify if:

  • the patient doesn't align with any of the criteria mentioned above
  • the patient is incapable of filling out the questionnaire/questionnaires' parts that are accorded to him/her
  • the patient doesn't agree to have data collected of him/her
  • diagnosed heavy, not treated chronic illness
  • not properly carried out /not evaluable lung function (spirometry) examination

The data sharing plan contains statements on the availability of individual participant data (including data dictionaries), information on what data in particular will be shared, what other documents will be available, when will data be available, with whom, for what type of analyses. In addition, the plan specifies the mechanism the data are be made available. According to the plan those IPD will be available that underlie the results published in research article(s) will be shared after deidentification. The frame of IPD sharing is defined below:

Shared Documents
STUDY PROTOCOL
Time Frame
Between months 9 and 36 after the publication of article(s).
Access Criteria
IPD (individual patient data) will be shared with investigators whose proposed use of the data has been approved by an independent review committee identified for this purpose. IPD will be shared to achieve aims in the approved proposal. Proposal may be submitted to farkasar@gmail.com.
