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.

| BE1116 | Biological | A single dose of BE1116 will be administered by intravenous (IV) infusion intraoperatively. |
|
| Measure | Description | Time Frame |
|---|---|---|
| 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. | At Day 1 after IP infusion (30 minutes after the end of infusion) |
| Measure | Description | Time Frame |
|---|---|---|
| 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. |

CSL will consider on a case-by-case basis requests to share Individual Patient Data (IPD) with external bona-fide, qualified scientific and medical researchers. For information on the process and requirements for submitting a voluntary data sharing request for IPD, please contact CSL at clinicaltrials@cslbehring.com.
Requests for IPD will generally be considered once review by major regulatory authorities (ie FDA, EMA) is complete and the primary publication is available.
Proposed research should seek to answer a previously unanswered important medical or scientific question.
Applicable country specific privacy and other laws and regulations will be considered and may prevent sharing of IPD.
If the request is approved and the researcher has executed an appropriate data sharing agreement, IPD that has been appropriately anonymized will be available.

| FFP | Biological | A single dose of FFP will be administered as investigational product (IP) by IV infusion intraoperatively. |
|
| Up to 24 hours after the end of IP infusion |
| 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. | At Day 1 after IP infusion (30 minutes after the end of infusion) |
| Change in INR from Baseline | From baseline (before IP infusion), to 30 minutes, 6 hours, 24 hours, and 48 hours after the end IP infusion |
| 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. | Up to 24 hours after the start of IP infusion |
| Change in Z-Scores for ROTEM EXTEM CT and TEG Reaction Time | Measurements on either ROTEM EXTEM CT or TEG reaction time will be collected. To combine these measurements, z-scores will be calculated for each method of measurement. The z-score standardizes each measurement by subtracting the mean and dividing by the standard deviation of the respective method. | From baseline (before IP infusion) to 30 minutes and 24 hours after the end IP infusion |
| Change in Bleeding Severity Scale (BSS) Score From Baseline | The BSS is a validated intraoperative scale used in clinical studies of hemostatic agents as a measure of bleeding severity. Bleeding is scored on a scale from 0 (no bleeding) to 4 (unidentified or inaccessible spurting or gush). A lower score indicates a better outcome. | From baseline (before IP infusion) to 30 minutes after end of IP infusion |
| Number of Participants in Each Universal Definition for Perioperative Bleeding (UDPB) Class | Bleeding is assessed based on 9 events occurring during surgery or within the first postoperative day. These 9 events will be used to determine UDPB class ranging from Class 0 to 5 as follows: Class 0 (insignificant), Class 1 (mild), Class 2 (moderate), Class 3 (severe), and Class 4 (massive). | During surgery (Day 1) and on the first postoperative day (Day 2) |
| Total Number of Units of Allogeneic Blood Products (ABPs) Administered | The ABPs include whole blood, cryoprecipitate, platelets, red blood cells (RBCs), and FFP (except the dose administered as IP). For the purposes of this study, a dose of fibrinogen concentrate will be counted as an ABP, because it is administered in lieu of cryoprecipitate. | From the start of IP infusion and up to 24 hours and 5 days after surgery |
| Number of Units of Individual ABPs Administered | The ABPs include whole blood, cryoprecipitate, platelets, RBCs, and FFP (except the dose administered as IP). For the purposes of this study, a dose of fibrinogen concentrate will be counted as an ABP, because it is administered in lieu of cryoprecipitate. | Up to 24 hours after the start of IP infusion |
| Volume of Chest Tube Output | Up to 24 hours after the end of surgery |
| Number of Participants Requiring Reoperation for Bleeding and for Other Reasons | Up to 30 days after surgery |
| Duration of Mechanical Ventilation | The duration of mechanical ventilation is defined as the number of days on mechanical ventilation after the study surgery. If there are multiple incidences of mechanical ventilation, the duration will be the sum of the number of days for all incidences. | Up to 30 days after surgery |
| Duration of Primary Intensive Care Unit (ICU) Stay | The duration of primary ICU stay is defined as the number of days in the ICU after the study surgery. | Up to 30 days after surgery |
| Duration of Primary Hospital Stay | The duration of primary hospital stay is defined as the duration in calendar days from the date of IP administration to the date of primary hospital discharge, or death in the hospital, or end of study (EOS) visit, whichever occurs first. | Up to 30 days after surgery |
| Number of Deaths | Up to Day 1 during the primary hospital stay, and within 28 days following IP infusion |
| Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious TEAEs, and Adverse Events of Special Interest (AESIs) | Up to 30 days after IP infusion |
| Change in Plasma Concentrations of Coagulation Factor II (FII), Factor VII (FVII), Factor IX (FIX), and Factor X (FX), and Proteins C and S From Baseline | From baseline to 30 minutes after the end of IP infusion |
| Plasma Concentrations of Coagulation FII, FVII, FIX, and FX and Proteins C and S | Up to 48 hours after the end of IP infusion |
