Main objective

Scope: Therapy, Efficacy, Dose response, Safety

The primary objective of this study is to evaluate the efficacy of two different doses of Atenativ, versus placebo, in restoring and maintaining heparin responsiveness in adult patients undergoing cardiac surgery necessitating cardiopulmonary bypass (CPB)

Secondary objectives 10

  1. The amounts of further therapy containing antithrombin required for restoring heparin responsiveness before CPB and maintaining it during CPB
  2. The effect of Atenativ on the coagulation parameter used for evaluating heparin resistance, namely the activated clotting time (ACT)
  3. The capacity of Atenativ to modify the antithrombin plasma concentration
  4. The impact of Atenativ on the intraoperative use of heparin following the infusion of Atenativ or placebo
  5. Any requirement for frozen plasma (FP) or antithrombin concentrates for reasons other than restoring or maintaining heparin responsiveness, both intraoperatively and postoperatively
  6. Any intraoperative and postoperative use of other allogeneic blood products, coagulation factor concentrates and other haemostatic-relevant therapies
  7. The volume of chest tube drainage and the need for reoperation due to bleeding
  8. The safety of Atenativ
  9. Any post-CPB requirement for additional therapy containing antithrombin to restore heparin responsiveness
  10. The patient’s postoperative course, as assessed by length of intensive care unit (ICU) stay.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 5

  1. Planned cardiac surgery with CPB
  2. Heparin-resistant patients: pre-CPB Hemochron ACT less than 480 seconds in the measurement performed between 2 and 5 minutes following intravenous administration of 500 U/kg BW UFH
  3. Patients ≥18 and ≤85 years of age
  4. Freely given written or electronic informed consent
  5. In female patients of childbearing potential (i.e., fertile, following menarche and until becoming post-menopausal unless permanently sterile), a pre-existing negative pregnancy test within 14 days prior to surgery

Exclusion criteria 9

  1. Receiving or have received one or more of the following medications within the specified time frames prior to the start of the surgery: a) vitamin K antagonists (within 3 days) b) direct oral anticoagulants (within 2 days) c) thienopyridines (ticlopidine within 14 days, prasugrel within 7 days, or clopidogrel within 5 days), unless platelet function is satisfactory d) ticagrelor (within 5 days), unless platelet function is satisfactory e) glycoprotein IIb/IIIa antagonist (within 24 hours)

  3. Renal insufficiency, defined as serum creatinine level >2.0 mg/dL
  4. Thrombocytosis, defined as platelet count >400,000 per µL
  5. Known hypersensitivity or allergic reaction to antithrombin or any of the excipients in Atenativ, i.e., human albumin, sodium chloride, acetyl tryptophan and caprylic acid

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The primary efficacy endpoint is the percentage of patients in each group in whom no further therapy containing antithrombin (i.e., FP or other antithrombin concentrates) is needed for restoring pre-CPB heparin responsiveness after administration of Atenativ or placebo, and for maintaining it during CPB.

Secondary endpoints 17

  1. The comparison between the amounts of further therapy containing antithrombin (i.e., FP or antithrombin concentrates) needed for restoring pre-CPB heparin responsiveness after administration of Atenativ or placebo, and for maintaining it during CPB
  2. The comparison between the change in ACT values following infusion of each of the Atenativ doses and placebo
  3. The comparison between the change in antithrombin plasma levels following infusion of each of the Atenativ doses and placebo
  4. The comparison between heparin usage following the infusion of each of the Atenativ doses and placebo
  5. The comparison between the number of units of FP transfused for reasons other than restoring or maintaining heparin responsiveness, both intraoperatively (from the start of Atenativ or placebo infusion until the start of CPB, during CPB, and from the end of CPB until the end of surgery) and postoperatively (from the end of surgery until 24 hours after the start of Atenativ or placebo infusion and until discharge or 7 days after surgery, whichever comes first), as well as cumulatively
  6. The comparison between postoperative use of antithrombin concentrates for reasons other than restoring heparin responsiveness (from the end of surgery until 24 hours after the start of Atenativ or placebo infusion and until discharge or 7 days after surgery, whichever comes first)
  7. The comparison between transfusion of other allogeneic blood products (i.e., red blood cells [RBCs], platelets, cryoprecipitate, whole blood, albumin, other transfusion), both intraoperatively and postoperatively, as well as cumulatively
  8. The comparison between administration of coagulation factor concentrates (fibrinogen concentrate, prothrombin complex concentrate (PCC), factor XIII concentrate, recombinant activated factor VII, other therapy), both intraoperatively and postoperatively, as well as cumulatively
  9. The comparison between administration of other haemostatic-relevant therapies (i.e., tranexamic acid, aminocaproic acid, protamine, other therapies), both intraoperatively and postoperatively, as well as cumulatively
  10. The comparison between postoperative chest tube drainage volume at 24 hours after the start of Atenativ or placebo infusion, and the comparison between total chest tube drainage volume until discharge or 7 days after surgery, whichever comes first
  11. Comparison of the need for reoperation for bleeding, including description of the cause of bleeding (surgical vs. non-surgical)
  12. The comparison between cell saver volume until the end of surgery
  13. Incidence of AEs in the three study groups
  14. Standard haematological parameters (i.e., RBC count, white blood cell count, haemoglobin levels, haematocrit, and platelet count) following Atenativ or placebo infusion, after the end of CPB, at the end of surgery, and at 24 hours after the start of Atenativ or placebo infusion
  15. Survival status in the different treatment groups.
  16. The comparison between the amounts of further therapy containing antithrombin (i.e., FP or antithrombin concentrates) needed for restoring heparin responsiveness from the end of CPB until 24 hours after start of Atenativ or placebo infusion and from the end of CPB until discharge or 7 days postoperatively, whichever comes first
  17. Comparison of the length of ICU stay between treatment groups.
