About this study

Official title: Clinical and dEmographic chaRacteristics of Patients With Frequent COPD Exacerbations and Evaluation of Therapeutic Approaches in Treatment in Moscow

This Study is multicenter, non-interventional, ambispective registry to evaluate the demographic and clinical characteristics, therapeutic approaches and outcomes in COPD outpatients with frequent exacerbations in Moscow

Read the detailed description

This ambispective study consists of retrospective and prospective parts:

  • Retrospective part aims to describe the demographic and clinical characteristics, as well as therapeutic approaches in COPD outpatients with frequent exacerbations during the 52 weeks prior to screening;
  • Prospective part aims to evaluate current therapeutic approaches for such patients and their outcomes in real-world clinical practice.

The patient participation in the study will include two visits:

  • Visit 1 - baseline: inclusion into the study, retrospective collection of medical history and data on COPD course and treatment during the previous 52 weeks, and primary data collection trough patient interview and physician assessment;
  • Visit 2 - follow-up at Week 24 (±6): primary data collection trough patient interview and physician assessment.

All visits will be conducted by a study physician in accordance with routine clinical practice for the observation and management of COPD patients. For each eligible patient, the study physician will collect data in an individual electronic Case Report Form (eCRF) based on source medical documentation.

Expected duration of the inclusion period is 12 months OR until 500 eligible patients are included into the study, whichever occurs first. Overall expected duration of the study (from the first patient inclusion to the last patient last visit) is approximately 25 months.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 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 3 Sep 2026. 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 Russia. 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 AstraZeneca Clinical Study Information Center (1-877-240-9479, information.center@astrazeneca.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To describe the baseline mean age of outpatients with COPD in Moscow. (time frame: 52 weeks of retrospective data before visit 1). The study lists 22 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07307781.

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 3 Sep 2026.
