Secondary Outcome Measures:
  • MACE @ discharge and 30 days post surgery; Change in renal function; Renal failure; Increased Cardiac Troponin T; Death rate; MI/stroke; Supplemental RBC transfusions; Total units RBC and HBOC-201; Intra Aortic Balloon Pump use, pump time; New onset CHF [ Time Frame: Duration of the study ]

Estimated Enrollment: 60
Study Start Date: February 2006
Estimated Study Completion Date: September 2008
Estimated Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: HBOC-201 (hemoglobin glutamer-250 bovine)
HBOC-201 is an investigational solution of purified, glutaraldehyde-polymerized bovine hemoglobin with a concentration of hemoglobin of 13 ± 1 g/dL
No Intervention: 2

Detailed Description:
The primary objective is to determine the safety and feasibility of administering Hemopure® (HBOC-201) to reduce myocardial necrosis, as measured by CK-MB enzyme elevation, and enhance tissue preservation during cardiopulmonary bypass.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subject is between the ages of 18 and 80.
  • Subject is an acceptable candidate for CABG.
  • Subject is scheduled for CABG (without planned valvular repair or replacement) by cardiopulmonary bypass.
  • Subject signs informed consent
  • Subject and the treating physician agree that subject can comply with all study procedures and follow-up visit at time of subject screening.

Exclusion Criteria:

  • Pre-operative myocardial infarction, defined as CK-MB level > 2 times upper limit of normal 24 hours prior to CABG surgery.
  • Renal failure defined as serum creatinine greater 220 µmol/L
  • Subject has an ejection fraction ≤ 30% (as measured by Echocardiography within 30 days of study enrollment).
  • Active infection.
  • History of prior stroke within last six months or history of prior stroke with residual neurological deficit.
  • Transient Ischemic attack within last 6 months.
  • Subject has a history of coagulopathy.
  • Subject is pregnant or currently breastfeeding.
  • History of allergy to beef products.
  • Pre-operative cardiogenic shock defined as cardiac index ≤ 1.8.L/min/m2 despite the use of vasopressors.
  • Underlying medical conditions that would limit subject's life expectancy to less than 12 months.
  • Severe pulmonary disease [based upon clinical diagnosis or pulmonary function tests (FEV <1 liter), if available] that may interfere with weaning subject from ventilator.
  • History of acute central nervous disorder (e.g., seizure or traumatic injury).
  • Severe hypertension (≥ 160/90 mm Hg) that cannot be medically controlled despite treatment with two antihypertensive therapies.
  • Severe liver dysfunction as defined by total bilirubin ≥ 51 µmol/L or 2 times the site normal limit of AST or ALT activity.
  • Subject has systemic mastocytosis.
  • Subject has any condition that predisposes the subject to systemic mast cell degranulation or hypersensitivity reactions or a history of severe allergic reactions to drugs or environmental allergens.
  • Subject has participated in another investigational drug, biologic or device study within 30 days prior to study enrollment.
