Trial summary

Alpha-1-antitrypsin deficiency is the most common congenital disease of the respiratory system, leading to early pulmonary emphysema or bronchiectasis. Pulmonary involvement significantly accelerates active cigarette smoking. Read more about this study

About this study

Official title: Czech Alpha-1 Antitrypsin Deficiency Registry, the National Observational Study.

Alpha-1-antitrypsin deficiency is the most common congenital disease of the respiratory system, leading to early pulmonary emphysema or bronchiectasis. Pulmonary involvement significantly accelerates active cigarette smoking. Patients with alpha-1-antitrypsin deficiency may also have liver cirrhosis, vasculitis, skin or intestinal disorders.

The AATD Registry is a non-interventional multicenter retrospective prospective longitudinal follow-up of patients with alpha-1-antitrypsin deficiency.

The aim of the AATD National Registry is to collect and analyze clinical data in patients with alpha-1 antitrypsin deficiency.

Read the detailed description

Alpha-1 antitrypsin deficiency is a genetic disorder that may result in lung disease or liver disease. It is assume that it affects 1 person from a cohort of 2,000-5,000 people of the general population. Among patients with COPD, the incidence of the disorder is significantly higher. The prognosis of these patients is incomparably worse compared to classic COPD, because it affects younger patients and the rate of lung tissue loss is faster. The diagnosis is made in patients with pre-existing COPD by examination of the plasma concentration of AAT. In case of its reduction, genetic examination is added. The progression of the disease is rapid and has been shown to be slowed by lifelong augmentation treatment with human AAT. However, in routine clinical practice, it is very difficult to assess the effectiveness of treatment, the progression of lung disease or the prognosis of the disease.

The AATD registry is a non-interventional multicenter retrospective prospective longitudinal follow-up of patients with alpha-1-antitrypsin deficiency. The national registry collects data from all patients with severe or rare AAT deficiency, regardless of the type of organ impairment and age, and thus provides a view of this genetic variation in the Czech population.

The aim of the AATD Registry is to collect and analyse clinical data of patients with alpha-1 antitrypsin deficiency and increase the professional awareness of this hereditary disease.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes of lung function parameters over time

    assessement of the rate of decline of FEV1 (ml, %predicted), measured annually

    Measured: within one year after completion

  2. Changes of exercise tolerance tolerance over time

    assessment of changes of peak oxygen consumption (peakVO2, ml/kg/min) measured every two years

    Measured: within one year after completion

  3. Changes of respiratory function over time

    assessement of the rate of decline of TLco (mol/min/kPa, %predicted), measured annually

    Measured: within one year after completion

  4. Changes of quality of life over time

    assessement of the rate of decline of COPD assessment test (CAT, points), measured annually

    Measured: within one year after completion

  5. Relationship of pulmonary function and lung CT densitometry to better determine phenotypes of COPD due to AAT deficiency

    Assessement of any possible relationship of primary outcomes 1-3 using LAA (low attenuation area, %) and distribution of emphysema (craniocaudal distribution of emhysema, points)

    Measured: within one year after completion

Secondary outcomes (2)
  1. Behavior of individuals with no or minimal lung involvement

    Assessement of prognosis of deficient non-smokers by monitoring primary outcome parameters 1-3

    Measured: within one year after completion

  2. Progression of other organ disorders, namely liver

    Laboratory detection of changes in liver tests (ALT, AST, ALP, GGT, ukat/l)

    Measured: within one year after completion

Questions about this trial

What is this clinical trial studying?

An observational study of Alpha-1-antitrypsin Deficiency, run by Thomayer University Hospital at 1 site in Czechia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 5 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Czechia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Katerina Kusalova, Ing (+420723949465, kusalova@biostatistika.cz), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes of lung function parameters over time (time frame: within one year after completion). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2022.
