About this study
Official title: EArly Discharge After Transradial Stenting of CoronarY Arteries in High-Risk Patients of Bleeding: Bivalirudin to Reduce Bleeding EASY-B2B Study
RATIONALE:
Transradial coronary stenting is associated with less risk of access site complications and bleeding compared to femoral approach.
Read more
Major bleeding post-PCI is a strong independent predictor of mortality and MACE. Depending of the antithrombotic regimen and access-site used, bleeding related to access-site represents 50-80% of the cases. Whereas transradial approach minimizes the risks of access-site bleeding, it has no impact on non-access site bleeding.
Peri-procedural anemia is also an independent predictor of mortality and MACE.
With femoral approach, bivalirudin compared to heparin ± glycoproteins IIb-IIIa has been associated with a significant reduction in access-site and non-access site related bleeding.
In a post-hoc analysis of patients treated by transradial approach in ACUITY, there was a trend for non-access site bleeding (organ bleeding) with bivalirudin compared to heparin ± glycoproteins IIb-IIIa.
HYPOTHESES:
In patients at high-risk of peri-procedural bleeding, bivalirudin ± glycoproteins IIb-IIIa reduces the risk of bleeding compared to heparin ± glycoproteins IIb-IIIa.
In patients at high-risk of bleeding and undergoing transradial PCI, bivalirudin significantly reduces the incidence of non-access site bleeding and peri-procedural anemia.

What is being measured
The primary outcome is the main question the study is designed to answer.
Major bleeding and Mace
The primary end-points will be 1) the incidence of major bleeding (Replace-2 criteria) at hospital discharge and 2) the incidence of 24h post-PCI anemia (WHO criteria)
Measured: 24h post-PCI and Discharge
Secondary outcomes (1)
EFFICACY and SAFETY PARAMETERS
The composite of death, MI (def 1 : Tn-t > 0.1 and def 2 : CK-MB > 30μg/l), urgent revascularization and major bleeding at 30 days post-PCI.
The incidence of ARC-defined stent thrombosis at 30 days. The incidence of access-site hematoma according to EASY scale. The incidence of radial artery occlusion at hospital discharge according to echo-doppler evaluation
Measured: 30 days

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Bivalirudin and Heparin in people with Coronary Artery Disease, run by Laval University at 1 site in Canada.
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 8 inclusion and 3 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 31 Jan 2018. 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 Canada. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Olivier F Bertrand, MD, PhD (418-656-8711, olivier.bertrand@criucpq.ulaval.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Major bleeding and Mace (time frame: 24h post-PCI and Discharge). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 31 Jan 2018; AzTrials last refreshed its copy on 8 Nov 2026.
