Study acronym | HAVAS-Study |
Study objectives | Evaluation of the efficacy and safety of Haemate HS in this clinical setting |
Ethics approval(s) | Approved by the Ethics Committee of the Heinrich Heine University Medical Center (Duesseldorf, Germany) on 25 April 2007. First amendment approved on 28 November 2007. |
Health condition(s) or problem(s) studied | Severe intraoperative hemorrhage during aortic-valve replacement |
Intervention | Intervention group: Intraoperative infusion Haemate HS 500/1000 IU (vWF/F VIII:C concentrate), time of infusion according to inclusion criteria. Control group: Intravenous infusion of 0.9% NaCl solution (100 ml) |
Intervention type | Drug |
Pharmaceutical study type(s) | |
Phase | Not Specified |
Drug / device / biological / vaccine name(s) | Haemate HS (intraoperative infusion) |
Primary outcome measure | Intra- and postoperative transfusion requirements according to defined transfusion thresholds. |
Secondary outcome measures | 1. Requirement of rethoracotomy, assessed during patients stay at the intensive care unit 2. Surgeons' subjective rating of therapeutic efficacy after application of Haemate HS or placebo (classification of bleeding after therapy as "better", "equal" or "worse") 3. Survival (perioperative mortality, mortality during hospital stay, mortality within a 90 day period following surgery) 4. Duration of treatment on intensive care ward 5. Adverse events and therapy-related side effects, assessed within the first 10 days after surgery. A second assessment is carried out after 3 month (at day 90) |
Overall study start date | 19/10/2007 |
Completion date | 31/12/2009 |
Eligibility
Participant type(s) | Patient |
---|---|
Age group | Adult |
Lower age limit | 18 Years |
Sex | Both |
Target number of participants | 40 patients (20 per arm) |
Key inclusion criteria | 1. Patients with isolated valvular aortic stenosis or combined aortic-valve defect with prevailing stenosis (mean transvalvular gradient >50 mmHg) with severe bleeding during aortic-valve replacement 2. Age >18 years. 3. Written informed consent. 4. All patients that fulfill at least one of the following criteria 15 minutes after the end of extracorporal circulation and application of protamine: 4.1. Excessive bleeding without surgical explanation according to the surgeons' impression (Classification of bleeding as "normal", "moderate" or "excessive" by the surgeon. Classification as "excessive" bleeding leads to recruitment to the study). 4.2. Drainage volume >40 ml in 5 minutes following application of protamine and thorax closure. |
Key exclusion criteria | 1. Participation in other interventional studies that potentially impair the interpretation of results 2. History suggestive for inherited or acquired bleeding disorder 3. Written informed consent not to be obtained 4. Active endocarditis 5. Concomitant coronary heart disease 6. Agents impairing platelet function at the time of surgery 7. Pregnancy 8. Known or suspected intolerance against Haemate HS 9. Previous thromboembolic complications 10. Known hepatitis B, hepatitis C or HIV infection 11. Known or suspected intolerance against standard medication (e.g., heparin) 12. Emergency surgery within the last 7 days 13. Previous chemotherapy |
