Main objective
Scope: Efficacy, Safety
The primary objective of the study is to evaluate the efficacy of FGTW in combination with Standard of care versus Placebo in combination with Standard of care in reducing the need for allogeneic transfusions during the first 24 hours after IMP administration in complex cardiac surgery patients.
Secondary objectives 1
- - To evaluate the efficacy associated with the use of FGTW versus Placebo in reducing the number of RBC, FFP, and platelet concentrate transfusions between 24 hours after IMP administration and the hospital discharge - To evaluate the efficacy associated with the use of FGTW versus Placebo in reducing the blood drainage volume during 12 hours after IMP administration or skin closure whichever comes last - To evaluate the number of patients with total avoidance of allogeneic transfusions after IMP administration - To evaluate the safety of FGTW - To evaluate the impact of FGTW on mortality and surgical morbidity - To evaluate the duration of hospitalization in both treatment arms - To evaluate the length of stay in ICU in both treatment arms

| 1 | Screening "The patient will be considered screened after ICF signature. Once ICF signature, the screening period
can be undertaken. Visit 1 will occur within a maximum of 32 days before surgery (D32 to D-1) to confirm eligibility of the patient."

Randomised Controlled | None | Standard of care + FGTW: The dose of FGTW will be based on the values of FIBTEM MCF and patient’s weight and administered intravenously after CPB discontinuation and administration of protamine. The Standard of care for patient blood management in adult cardiac surgery is defined and based on the European Guidelines Standard of care + Placebo: The dummy dose for Placebo will be based on the values of FIBTEM MCF and patient’s weight and administered intravenously after CPB discontinuation and administration of protamine.

|
| 2 | Day of surgery and Randomization Visit 2 will occur on the day of surgery (D1). If FIBTEM MCF is ≤10 mm during the last 20 minutes of CPB and the calculated IMP dose is ≤8 g, patients will be randomized to either Standard of care + FGTW or Standard of care + Placebo using a 1:1 allocation stratified by center and gender. They will receive one administration of up to 6 vials of IMP depending on their FIBTEM MCF results and their weight.

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 8
- Male or female adult patients ≥18 years
- Patients undergoing a planned complex cardiac surgery procedure involving CPB, including reoperation and/or complex surgical procedures. Complex surgical procedures are defined as any procedure other than first time isolated coronary artery bypass grafting (CABG), single valve repair/replacement and repair of atrial septal defect (ASD). This criterion represents the main eligibility criterion and so used in the definition of the full analysis set.
- With a FIBTEM MCF ≤10 mm during the last 20 minutes of CPB.
- Patients requiring an IMP dose ≤8 g calculated with the formula based on patient's weight and the value of FIBTEM MCF
- Signed and dated informed consent form (ICF)
- Willingness to comply with all study procedures and availability for the duration of the study
- Covered by healthcare insurance in accordance with local requirements
- FIBTEM MCF ≤14 mm during the screening period prior to the surgery. FIBTEM MCF is the recommended test, for consistency with end of CPB FIBTEM MCF. Fibrinogen concentration (Clauss method) may be substituted, with fibrinogen level ≤3 g/L. Note: the objective of this criterion is to allow to screen fail patients unlikely to meet inclusion criterion #3 prior to surgery rather than at the end of CPB and reduce the patient’s and site’s constraints of continuing the screening process throughout surgery. However, a patient with a preoperative FIBTEM MCF > 14 mm (or plasma fibrinogen > 3 g/L) can, under exceptional circumstances, continue to be screened until FIBTEM MCF measurement during the last 20 minutes of CPB, if, in the investigator’s judgement, the patient is considered at high risk of clinically significant bleeding (e.g., complex multiple procedures or an expected very long duration - several hours - of CPB).
Exclusion criteria 21
- Heart transplantation
- Repair of complex congenital abnormalities
- Any known pulmonary, hepatic, or renal disease or any other major concomitant significant medical condition that might interfere with treatment evaluation according to the Investigator's judgment
- Known hypersensitivity or other severe reaction to any component of the IMP
- Patients at high risk of thrombotic events unable to stop prophylactic low-molecular-weight heparin (LMWH) 12 hours and fondaparinux 24 hours before surgery (longer interval in case of impaired renal function)
- Patients unable to stop treatment by vitamin K antagonists 3-5 days before surgery to obtain an international normalized ratio (INR) <1.5
- Patients unable to stop treatment by direct oral anticoagulant at least 48 hours before surgery (except aspirin)
- 8. Patients unable to stop treatment by P2Y12 inhibitors before surgery (discontinuation duration before surgery: ticagrelor 3 days, clopidogrel 5 days, and prasugrel 7 days)
- Severe anemia with hemoglobin (Hb) ≤10 g/dL
- Excessive hemodilution with hematocrit (Ht) <22% in men and women at the time of taking sample for FIBTEM MCF during the last 20 minutes of CPB
- Congenital coagulation deficiencies (von Willebrand disease, factor V Leiden, Protein C deficiency, cryoglobulinemia, antiphospholipid syndrome…)
- Any known thromboembolic disorder
- Female of reproductive potential not using effective contraception (condoms; occlusive caps with spermicide; injectable, patch, or combined oral estro-progestative or progestative contraceptives; depot intramuscular medroxyprogesterone; or subcutaneous implants of progestative contraceptive implants) for at least one month prior to screening
- Known pregnancy or positive blood pregnancy test for women of childbearing potential and/or breast-feeding women
- Participation in another clinical study involving an investigational medicinal product within 30 days prior to screening or or 5 half-lives of this investigational medicinal product, whichever is longer, or concomitantly with this study
- Treatment with fibrinogen concentrate or cryoprecipitate within 32 days prior to randomization
- Previous cardiac surgical procedure within three months before randomization
- Evidence or suspicion of infection (fever >38.5°C and white blood cell count >11/mm3)
- Active endocarditis
- Emergency surgery, patients in cardiogenic shock, or expected mortality within 24 hours of surgery
- Pre-existing thrombocytopenia with platelet count < 150 000/ mm3

- Mortality at 24 hours, 7 days, and 30 days after IMP administration
- Percentage of patients with each surgical morbidity at 24 hours, 7 days, and 30 days after randomization (see Section 9.2.8)
- Percentage of patients with post-surgery stage 1 AKI (with increase in creatinine by >50% from baseline until hospital discharge)
- Percentage of patients with surgical re-exploration due to bleeding during 24 hours after IMP administration
- Percentage of patients with fibrinogen concentration below the LLN from visit 2 to visit 5
