About this study

Official title: The Haemostatic Effect of Deep-frozen Platelets Versus Room Temperature Stored Platelets in the Treatment of Traumatic or Vascular Bleeding. MAFOD: a Randomized Controlled Non-inferiority Trial

Primarily due to its logistical advantages The Netherlands Armed Forces (NLAF) have been successfully using deep frozen (-80°C) platelets (DTC) for the treatment of (massive) bleeding trauma patients in austere environments since 2001. However, high-quality evidence for effectiveness and safety in the treatment of these type of patients is currently lacking. The MAssive transfusion of Frozen bloOD (MAFOD) trial is therefore designed to compare the haemostatic effect of DTCs versus room temperature stored platelets (RSP) in the treatment of trauma- and vascular bleeding.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Deep-frozen platelets in people with Trauma and Bleeding, run by Alrijne Ziekenhuis Leiderdorp.

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 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: status not confirmed, as of the sponsor's last update on 1 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Tim Rijnhout (0715828282, twhrijnhout@alrijne.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of patients that achieved haemostasis and show signs of life. (time frame: At six hours). 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 NCT05502809, 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 1 Feb 2023.
