Study summary

This study will evaluate the diagnostic measures (including blood eosinophil counts) commonly used by lung specialist's in routine clinical care of subjects with COPD in Germany and how these diagnostic tests influence the physician's treatment decisions. The study will be conducted in three parts. In the first part, lung specialist's, who will not participate in the survey, will develop doctor's questionnaire. The second part is an interventional cross-sectional study, wherein approximately 30 lung specialists will be enrolled and data on their perspective on diagnosis and treatment of COPD subjects will be collected via the revised doctor's questionnaire. The third part is a retrospective non-interventional study where each doctor will collect retrospective data from selected subjects with COPD from the time of informed consent up to 12 months before. The retrospective data will be collected from subject files of approximately 250 subjects with COPD.

Study population

Approximately 30 lung specialists (up to 50) in Germany with sufficient number of COPD subjects under supervision in a hospital or office based setting will be enrolled in the study. Data from the survey of lung specialists and retrospective medical data of 250 subjects with COPD under supervision of the 30 lung specialists (up to 50) enrolled in the study will be included in the analysis.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

For participating centers (Sample 1: 30 lung specialists from Germany)

  • More than 10 years of experience in respiratory medicine
  • At least 500 subjects under supervision in hospital- or office-based setting: a) Focus on obstructive lung diseases. b) Board certification. c) to participate in this study and to share files of consenting subjects.

For subjects (Sample 2: 250 subjects from these 30 doctors from sample 1)

  • Written informed consent to use his/her data.
  • Age >=40 years
  • Pack years >10, current or former smoking
  • Duration of COPD: >=1 year since COPD diagnosis record in subject files (also confirmed by spirometry)
  • No concurrent asthma diagnosis
  • At least one year of documented disease history at participating study doctors and have to be under the care of the before mentioned physician during this time because of COPD.

Exclusion criteria

Exclusion Criteria:

  • Subjects who are pregnant and breastfeeding (in the last 12 months)
  • Subjects currently participating in any interventional study
  • Subjects with severe comorbidities which would have influence on the therapy
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 15, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
