About this study

This is an observational study based on data collected via an audit of electronic medical charts. The study population will include adult US patients treated with andexanet alfa or 4F-PCC during a hospitalization for an anticoagulation-related major bleed, and their characteristics, treatments and outcomes will be described.

Read the detailed description

This observational study will include adult US patients treated with andexanet alfa or 4F-PCC during a hospitalization for an anticoagulation-related major bleed. Data will be collected via an audit of electronic medical charts. The primary objectives are to describe the patients' characteristics, treatments and outcomes, including length of stay and in-hospital mortality. Secondary objectives include subgroup analyses, including by bleed location. Potential differences between patients treated with andexanet alfa versus 4F-PCC, and potential differences in patient characteristics over time, will be assessed. If this assessment confirms that treatment groups can be adequately balanced and that patient characteristics have not substantially changed over time (i.e. no channeling bias is observed), the risk of in-hospital mortality with andexanet alfa versus 4F-PCC will be assessed in a comparative effectiveness analysis. If treatment groups cannot be balanced or clear signs of channelling bias are observed, the comparative analyses will be considered unfeasible and will not be performed.

Questions about this trial

What is this clinical trial studying?

An observational study of Anticoagulant-related Major Bleed, run by AstraZeneca at 1 site in United States.

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 4 inclusion and 2 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 28 Nov 2023. 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 United States. 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.

What does the primary outcome measure?

Mortality (time frame: During hospitalisation, approximately 6 days). 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 NCT05548777, which also lists 2 linked publications.

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 28 Nov 2023.
