Plain English summary of protocol
Background and study aims
Newborn babies and infants needing surgery for congenital heart disease suffer the most from bleeding within the chest. As a result, they are frequently exposed to many blood products, and may also suffer consequences of blood loss. We want to find out whether giving a new blood product, human fibrinogen concentrate, to these infants, will reduce bleeding and exposure to other blood products. A unique aspect of this study will be that study drug exposure and dose will be personalised to the patient on the basis of bleeding risk. Because bleeding risk cannot be estimated accurately before the operation, we will assess this during the operation using a test for coagulation, known as rotational thromboelastometry (ROTEM).
Who can participate?
Babies who are aged less than 36 weeks with congenital heart disease requiring surgery.
What does the study involve?
We will give the study drug to only those infants who are at higher risk of bleeding during the ROTEM screening during the operation. These infants will be randomly allocated to receive either fibrinogen or a placebo (dummy). Infants at lower risk will not be allocated to any group, but remain in the study, forming an observational group. All infants will receive standard care with respect to all other aspects.
What are the possible benefits and risks of participating?
As this is an early phase trial, it is impossible to delineate risks or benefits in any meaningful way.
Where is the study run from?
Evelina Childrens Hospital (UK)
When is the study starting and how long is it expected to run for?
The study starts in June 2014 and ends in March 2016

| Scientific title | Fibrinogen concentrate supplementation in the management of bleeding during paediatric cardiopulmonary bypass: a phase 1B/2A, open-label dose-escalation study |
| Study objectives | Fibrinogen concentrate supplementation during paediatric cardiopulmonary bypass may decrease the incidence and severity of postoperative bleeding, and reduce the need for transfusion of blood and ancillary blood products (platelets, fresh frozen plasma, and cryoprecipitate). The primary objective of this trial is to determine the dose of intraoperative fibrinogen concentrate required to achieve physiological levels of fibrin polymerization of 8 to 13 mm as measured by the rotational thromboelastometry (ROTEM) measure of fibrin-based clotting: FibTEM MCF (equating to plasma fibrinogen concentrations of 1.5 to 2.5 g/L), immediately prior to separation from cardiopulmonary bypass in neonates and children < 12 kg. |

| Health condition(s) or problem(s) studied | Topic: Children; Subtopic: All Diagnoses; Disease: All Diseases |
| Intervention | Fibrinogen concentrate: IMP will be administered while on cardiopulmonary bypass. Patients will be screened while on cardiopulmonary bypass (approx 1 hour before end of operation) using Rotational Thromboelastometry: FibTEM MCF. If MCF<7mm, patients will be randomised to IMP:placebo 2:1. Dose will be tailored to patient based upon measured FibTEM MCF and desired target range.; Study Entry : Registration and One or More Randomisations |

| Key inclusion criteria | 1. Congenital heart disease requiring non-emergency* surgery on cardiopulmonary bypass 2. Age range: >36 weeks corrected gestation 3. Weight 2.5 to 12 kg 4. Informed consent to participate *Non-emergency is defined as surgery that can be delayed >24 hours following diagnosis of congenital heart disease |
| Key exclusion criteria | 1. Known pre-existing inherited coagulopathy 2. Known pre-existing inherited thrombophilia 3. Recent, acute (within previous 2 weeks) thrombosis in a major vessel or thrombotic related major complications (as defined in protocol sections 2.43 and 7.3) 4. Administration of antiplatelet agents (e.g. aspirin) <48 hours prior to surgery 5. Known hypersensitivity/allergy to the study drug or similar products 6. History of anaphylaxis 7. Enrolment in another clinical trial in the previous 3 months 8. Parent/guardian unable to provide informed consent (this can include insufficient understanding of the trial, as judged by the clinician taking consent) 9.
