About this study

The aim of the RAPID study is to assess the rapid onset of action of the 2 novel oral antiplatelet agents, Prasugrel and Ticagrelor, in 50 patients with STEMI undergoing PPCI with bivalirudin monotherapy.

Read the detailed description

Fifty consecutive patients with STEMI undergoing PPCI with bivalirudin (GP IIb/IIIa not allowed ) will be randomized to receive 60 mg Prasugrel loading dose (n= 25) or 180 Ticagrelor loading dose (n= 25) before PPCI. The loading dose will be performed as soon as possible in the Emergency Room or in the Cath Lab. In the case of vomit in the 2 hours after drug loading dose a new loading dose will be administered. All interventions will be performed by the femoral approach according to current standards. The use of thrombectomy before infarct-related artery stenting, of everolimus eluting stent and of closure devices will be strongly encouraged. Bivalirudin will be administered as a bolus 0.75 mg/kg followed by 1.75 mg/kg/h infusion during PCI. After PCI a reduced bivalirudin infusion of 0.25 mg/kg/h for 4 hours will be allowed. Dual antiplatelet therapy (100 mg aspirin associated with 5 or 10 mg Prasugrel or 180 mg Ticagrelor) will be recommended for 12 months.

Residual platelet reactivity will be assessed in all patients at baseline (time of loading dose), and after 2, 4, 8 and 12 hours by a point-of-care test VerifyNow bedside available in the Intensive cardiac care Unit. High residual platelet reactivity will be defined as a Platelet Reactivity Units (PRU) > 240 by VerifyNow. At the same time point, Activated Clotting Time (ACT) will be also assessed. Follow-up will be performed by outpatient visits or telephone interviews at 6 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PrasugrelDrug

    25 patients with STEMI undergoing PPCI with bivalirudin (GP IIb/IIIa not allowed ) will be enrolled to receive 60 mg Prasugrel loading dose before PPCI. The loading dose will be performed as soon as possible in the Emergency Room or in the Cath Lab. In the case of vomit in the 2 hours after drug loading dose a new loading dose will be administered.

  • TicagrelorDrug

    25 patients with STEMI undergoing PPCI with bivalirudin (GP IIb/IIIa not allowed ) will be enrolled to receive 180 Ticagrelor loading dose before PPCI. The loading dose will be performed as soon as possible in the Emergency Room or in the Cath Lab. In the case of vomit in the 2 hours after drug loading dose a new loading dose will be administered.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Residual platelet reactivity by VerifyNow

    Residual platelet reactivity will be assessed in all patients at baseline (time of loading dose), and after 2 hours by a point-of-care test VerifyNow bedside available in the Intensive cardiac care Unit.

    Measured: 2 hours

Secondary outcomes (1)
  1. High residual platelet reactivity

    High residual platelet reactivity will be defined as a Platelet Reactivity Units (PRU) > 240 by VerifyNow.

    Measured: 2,4,8,12 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Prasugrel and Ticagrelor in people with ST-segment Elevation Myocardial Infarction, run by Careggi Hospital at 1 site in Italy.

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 2 inclusion and 15 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 25 Sep 2014. 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 Italy. 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?

Residual platelet reactivity by VerifyNow (time frame: 2 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 NCT01510171, 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 25 Sep 2014.
