  • Known allergy to Angiomax or hirudin derived drugs, or known sensitivity to any component of these products.
  • Patients receiving clopidogrel within the previous 5 days of randomization.
  • Patients receiving a glycoprotein IIb/IIIa inhibitor within 48 hours if abciximab (ReoPro) or within 24 hours if eptifibatide (Integrilin) and tirofiban (Aggrastat) of randomization

About this study

Official title: A Study Comparing Angiomax (Bivalirudin) to Heparin With Protamine Reversal in Patients Undergoing Coronary Artery Bypass (OPCAB) Surgery

What participants receive

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

  • BivalirudinDrug

    250 mg vial administered as 0.75 mg/kg intravenous (IV) bolus and 1.75 mg/kg/h IV infusion for the duration of surgery with the option to increase or decrease the infusion in 0.25 mg/kg/h increments or to administer additional 0.1-0.5 mg/kg boluses to maintain an activated clotting time (ACT) >300 seconds (s).

  • HeparinDrug

    : Per institutional practice, at 1.5-3.5 mg/kg (200-400 U/kg) IV bolus to achieve a target ACT of >300 s followed by weight-adjusted boluses as needed during surgery to achieve/maintain the target ACT. Batches from hospital stock.

  • ProtamineDrug

    Per institutional practice. Batches from hospital stock.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Bivalirudin, Heparin and Protamine in people with Cardiac Surgery and Coronary Artery Bypass Surgery, run by The Medicines Company at 1 site in United States.

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 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 10 Nov 2011. 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 United States. 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 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?

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 (time frame: Hospital discharge or Day 7). The study lists 4 primary outcomes in all. 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 10 Nov 2011.
