About this study

Official title: P2Y12 Inhibitors Utilization in Bifurcation and Chronic Total Occlusion PCI With Biologically Active Stents (P2BiTO) Registry

Prasugrel and ticagrelor were both associated with a significant reduction in the risk of MACE in patients undergoing PCI for an ACS, mostly through a reduced stent thrombosis. The 1-year relative risk reduction (RRR) of definite of probable stent thrombosis in patients receiving a DES were fairly different in TRITON-TIMI 38 and PLATO trials. The incidence of "biologically active" stent (DES or BVS) thrombosis is largely variable according to different lesion settings. We aim to verify the translation of the postulated different reduction in thrombosis rate among various P2Y12 inhibitors (clopidogrel, prasugrel and ticagrelor) in a high-risk setting such as the PCI with DES or BVS in CTO and bifurcating lesions.

Read the detailed description

All patients aged 18-80 who underwent PCI of a CTO or bifurcating lesion (all Medina types, side branch ≥2 mm) with "biologically active stents" (DES or BVS) between January 2012 and december 2014 at participating centers will be deemed eligible to enter the registry.

In-hospital outcomes will be recorded; all patients discharged alive will be followed up with a telephone interview (minimum follow-up 6 months).

The primary end-point will be the occurrence of a cluster of major adverse cardiovascular events at 1 year:

  1. Death from any cause.
  2. Myocardial infarction.
  3. Stent thrombosis, defined as definite, probable or possible following the Academic Research Consortium.

Sample size 3150 patients.

What is being measured

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

  1. Death, Myocardial infarction, Stent Thrombosis

    1. Death from any cause.
    2. Myocardial infarction, defined as an elevation of the creatine kinase MB fraction or cardiac troponins by a factor of 3 or more, or the development of new Q waves in 2 or more contiguous leads at surface ECG7. Levels of total creatine kinase and the creatine kinase MB fraction will be measured in all patients between 12 and 24 hours after PCI.
    3. Stent thrombosis, defined as definite, probable or possible3 following the Academic Research Consortium

    Measured: 30 months

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Arteriosclerosis, run by G. d'Annunzio University.

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 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: finished, as of the sponsor's last update on 30 Oct 2017. 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.

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?

Death, Myocardial infarction, Stent Thrombosis (time frame: 30 months). 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 NCT01967615, which also lists 8 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 30 Oct 2017.
