About this study

Official title: Longitudinal Assessment of Clinical and Molecular Pathology of Chronic Obstructive Lung Disease and the Possible Influence of Inert Dusts in Working Volunteers of the Greater Vienna Area

The main objective of the study is the exploration of the natural course of COPD and its biological background. To this end, active workers without COPD and workers in functional classes GOLD 0-III are investigated by a combined clinical and molecular approach. The study has been designed as a prospective, intraindividual pilot in 160 male or female volunteers of the greater Vienna Area over a period of three years for each individual volunteer.

Read the detailed description

Primary endpoint Combined assessment of clinical and molecular data obtained in three sequential study visits over an investigative period of 36 months for each individual; this includes, in particular, the identification of single and clustered gene functions connected to deterioration or stability of pulmonary function at the end of the observation period.

Secondary endpoints Assessment of occupational and environmental exposure to primarily inert fine dusts in a random subset of the strata by means of 24h-measurement of quantity and quality of fine dust inhalation; Influence of intensified exposure to fine dusts due to occupational conditions; Development of lung function in the five different study groups (see below), particularly changes from one GOLD class into the next class;

Definition of Study Groups:

Group 1 (Control):

Healthy volunteers, age 18 to 35 yr, never smokers (n=20).

Group 2 (preferentially taxi or bus drivers; COPD °0):

Working men/women, age 18 to 65 yr, preferentially taxi drivers or bus drivers or comparable occupational burden, current smokers or ex-smokers, with symptoms suggestive of COPD, yet regular lung function test at rest at the time of study entry, no signs of significant other diseases, in particular no signs of cardiovascular disease (n=35).

Group 3 (preferentially taxi or bus drivers; COPD °I-III):

Working men/women, preferentially taxi drivers or bus drivers or comparable occupational burden, age 35 to 65 yr, current smokers or ex-smokers, with symptoms of COPD, and abnormal lung function at rest at the time of study entry, no signs of significant other diseases, in particular no signs of cardiovascular disease (n=35).

Group 4 (Welder; COPD °0):

Working men/women, active welders or comparable occupational burden, age 35 to 65 yr, current smoker or ex-smoker, with symptoms suggestive of COPD, yet regular lung function test at rest, no signs of significant other diseases, in particular no signs of cardiovascular disease (n=35).

Group 5 (Welder; COPD °I-III):

Working men/women, active welders or comparable occupational burden, age 35 to 65 yr, current smoker or ex-smoker, with symptoms of COPD and abnormal lung function at rest at the time of study entry, no signs of significant other diseases, in particular no signs of cardiovascular disease (n=35).

Exclusion criteria:

  • COPD °IV
  • Bronchial asthma
  • Major cardiovascular diseases, in particular stroke and myocardial infarction with reduced cardiac function
  • Age > 65 years
  • Acute or chronic bronchial infections, in particular bronchiectasis
  • Cancer

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Disease, Chronic Obstructive, run by Medical University of Vienna at 1 site in Austria.

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 3 inclusion and 6 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: finished, as of the sponsor's last update on 24 Aug 2012. 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 Austria. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00618137, which also lists 1 linked publication.

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 24 Aug 2012.
