About this study

Official title: COMPARison of Pre-hospital CRUSHed vs. Uncrushed Prasugrel Tablets in Patients With STEMI Undergoing Primary Percutaneous Coronary Interventions

The studys evaluates the effect of prehospital administration of crushed tablets of Prasugrel loading dose (in addition to ASA and standard care) versus uncrushed tablets of Prasugrel loading dose on efficacy and safety as well as pharmacodynamics as measured by platelet reactivity using VerifyNow.

Read the detailed description

The study is a two-centre, randomized, 1:1 trial comparing prehospital prasugrel initiation therapy between crushed vs. uncrushed prasugrel tablets on efficacy and safety as well as pharmacodynamics in STEMI patients.

Patients with STEMI planned for primary PCI will be screened and, if inclusion criteria are met, included at first medical contact (paramedics). After enrolment, patients will be randomly assigned (1:1) to receive 60mg prasugrel loading dose by ingesting integral or crushed tablets.

The follow-up duration is 12 months, i.e. clinical outcomes will be analysed in-hospital, at 30 days, and 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Prasugrel (Crushed tablets) and Prasugrel (Integral tablets) in people with Cardiovascular Diseases, run by Maasstad Hospital at 2 sites in Netherlands.

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 5 inclusion and 13 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 7 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Netherlands. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

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?

Co-primary endpoint is the percentage of patients reaching TIMI flow grade 3 of MI culprit vessel at initial angiography or a ≥70% ST-segment resolution directly post-PCI (time frame: directly post PCI). 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 NCT03296540, 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 7 May 2021.
