One Harvard Way, Suite 5 Hillsborough Campus Somerville, NJ 08876 908-707-8872 Michael F. Corsello, 908-707-8872 Contact: October 12, 1998 Date: Device Names: Trade Names: MAX-ACT Activated clotting time test Common Name: Classification Name: Activated whole blood clotting time tests Legally Marketed Device: Array Medical Actalyke C-ACT test tube, K964609. Device Description: The MAX-ACT Activated Clotting Time test tubes utilize a "cocktail" of particulate activators (including celite, kaolin, and glass particles) and is intended for use in the measurement of the activated clotting time test (ACT) on Actalyke Models A1, A1P, A2, A2P, and Hemochron® Models 400, 401, 800, 801 and 8000. Intended Use: The MAX-ACT Activated Clotting Time test tubes are intended for use in the measurement of the activated clotting time test (ACT) on Actalyke Models A1, A1P, A2, A2P, and Hemochron® Models 400, 401, 800, 801 and 8000. {1}------------------------------------------------ Performance Data: Substantial equivalence of the MAX-ACT ACT test tubes to the Array Medical Actalyke C-ACT is supported by an in-house study. Whole blood was obtained from normal donors and heparinized in vitro up to 10.0 units of heparin/ml. Currently, the most common method for heparin monitoring in these heparinization ranges are the celite and kaolin based ACT tests (C-ACT (celite) and K-ACT (kaolin) (0.0-5.0 units/ml - 600 seconds) and HEMOCHRON CA510 (celite) (up to 600 seconds). Hemochron FTKACT (kaolin) (up to 600 seconds). The correlation of the MAX-ACT Activated Clotting Time test tube and various combinations of Actalyke and Hemochron instruments and ACT tubes were determined. In-vitro heparin sensitivity curves were generated from three normal, healthy volunteers. Samples (n=72) were generated by adding increasing amounts of heparin to aliquots of normal donor blood. MAX-ACT Activated Clotting Time Tests were performed. A positive correlation between the MAX-ACT and the C-ACT/FTCA510 was demonstrated when paired testing was performed. The MAX-ACT demonstrated a positive correlation with the C-ACT tubes (r=0.97, p=.0001, n=72) (Figure E1). The data is shown in Table E1. Studies were also conducted clinically at numerous institutions. A total of 330 paired blood samples were collected from patients (including adult bypass, pediatric bypass, and cardiac catheterization) before, during, and following heparinization. The patients were divided into four discrete groups. These groups consisted of: Study Group 1. Bypass Patients: Results obtained using a reference celite-based ACT test (C-ACT/FTCA510) were compared to those obtained using MAX-ACT test tubes. A total of 239 patient samples were collected from bypass patients (n=30) before, during, and following heparinization during cardiopulmonary bypass. The data vielded a correlation coefficient of r2 =0.82 (Figure E2) and r2 = 0.87 (Figure E3) when samples from the reference group were omitted which were outside the published linear range for the reference tube. The data is shown in Table E2. Study Group 2. Aprotinin Bypass Patients: Results obtained using a reference kaolin-based ACT test (ACTII/K-ACT/FTKACT) were compared to those obtained using MAX-ACT test tubes. A total of 28 patient samples were collected from bypass patients receiving antifibrinolytic therapy (aprotinin) (n=6) before, during, and following heparinization during cardiopulmonary bypass. The data yielded a correlation coefficient of r2 =0.89 (Figure E4). The data is shown in Table E3. {2}------------------------------------------------ Study Group 3. Pediatric Bypass: Results obtained using a reference celitebased ACT test (FTCA510) were compared to those obtained using MAX-ACT test tubes. A total of 41 patient samples were collected from pediatric bypass patients (n=5) before, during, and following heparinization during cardiopulmonary bypass. The data yielded a correlation coefficient of r2=0.86 (Figure E5). The data is shown in Table E4. Study Group 4. Catheterization Patients: Results obtained using a reference celite-based ACT test (FTCA510) were compared to those obtained using MAX-ACT test tubes. A total of 22 patient samples were collected from cardiac catheterization patients (n=10) before, during, and following heparinization during the procedure (diagnostic and interventional). The data vielded a correlation coefficient of 2 =0.88 (Figure E6). The data is shown in Table E5. {3}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/2 description: The image shows the logo for the U.S. Department of Health and Human Services.
