This is a phase 3, multicenter, randomized, open-label, parallel-group, controlled study to assess the efficacy and safety of BE1116 compared with fresh frozen plasma (FFP) in adult participants undergoing complex cardiovascular surgery with CPB. The primary purpose of the study is to compare the efficacy of BE1116 and FFP in correcting coagulation factor deficiencies in bleeding participants undergoing complex cardiovascular surgery with CPB.
Adult greater than or equal to (≥) 18 years and has provided written informed consent.
Undergoing elective complex cardiovascular surgery requiring CPB, including procedures of the thoracic aorta (with or without additional cardiac interventions), aortic valve replacement + coronary artery bypass graft (CABG), complex valve surgeries, mitral valve repair + CABG, and mitral valve replacement + CABG and reoperative CABG. Reoperative procedures are permitted. Excluded surgeries are as follows: heart transplantation, insertion or removal of ventricular assist devices (except for intra-aortic balloon pumps), and acute repair of thoracoabdominal aneurysms.
INR ≥ 1.6 (point-of-care INR testing by Hemochron ≥ 5 to 10 minutes after protamine infusion for heparin reversal). If a participant needs a second dose of protamine, a new INR measurement should be performed to confirm eligibility.
Significant microvascular hemorrhage (ie, not due to surgical complications), as defined by a BSS score of ≥ 2.
Administration of any systemic hemostatic therapy, such as cryoprecipitate, platelets, FFP, PCC (eg, 4-factor / 3-factor PCC [4F-PCC / 3F-PCC]), Factor VIII (FVIII) inhibitor bypassing activity (FEIBA), recombinant activated Factor VIIa (rFVIIa), or other coagulation factor products, in the 24 hours before study surgery, except when FFP is added to the CPB circuit.
Parallel
BE1116
Biological/VaccineA single dose of BE1116 will be administered by intravenous (IV) infusion intraoperatively.
FFP
Biological/VaccineA single dose of FFP will be administered as investigational product (IP) by IV infusion intraoperatively.
Number of Participants With and Without a Successful Correction of Coagulation Factor Deficiency
Successful correction ("yes" vs "no") of coagulation factor deficiency as measured by an international normalized ratio (INR) of less than or equal to (≤) 1.4 at 30 minutes after the end of IP infusion.
Number of Participants With Effective or Not Effective Hemostatic Response from 30 Minutes to 24 Hours After the End of IP Infusion
The hemostatic response will be recorded as either effective or not effective. 'Effective' is defined as no hemostatic intervention was required, whereas 'non effective' is defined as a hemostatic intervention was required in the period from 30 minutes to 24 hours after the end of IP infusion. Hemostatic intervention includes surgical re-intervention for bleeding and / or the administration of any systemic hemostatic agents.
Number of Participants With and Without Successful Correction of Coagulation Factor Deficiency
Successful correction ("Yes or No") of coagulation factor deficiency measured by a rotational thromboelastometry (ROTEM) extrinsically activated thromboelastometric test (EXTEM) clotting time (CT) ≤ 80 seconds or thromboelastography (TEG) reaction time ≤ 8 minutes. ROTEM and TEG are viscoelastic coagulation tests that quantify the process of clot formation and degradation.
Change in INR from Baseline
Number of Participants With Effective and Not Effective Hemostatic Response From the Start of IP Infusion to 24 Hours After the Start of IP Infusion
The hemostatic response will be recorded as either effective or not effective. 'Effective' is defined as no hemostatic intervention was required, whereas 'non effective' is defined as a hemostatic intervention was required in the period from the start of IP infusion to 24 hours after the start of IP infusion. Hemostatic intervention includes surgical re-intervention for bleeding and / or the administration of any systemic hemostatic agents.
