Plain English Summary

Background and study aims
Injury is a leading cause of death and disability worldwide. Around 7,800 people die in England every year, and many thousands more are left severely disabled. Uncontrolled bleeding is the main cause of death in 40% of cases. Transfusion therapy (which includes giving patients additional red blood cells, fresh frozen plasma, platelets and cryoprecipitate) is an important part of emergency treatment for major bleeding. Although the standard transfusion therapy is routinely followed in all hospitals, we are not sure whether by giving an additional source of fibrinogen, with a drug called fibrinogen concentrate, as quickly as possible works better than standard practice. The main objective of this clinical trial is to test whether it is possible to give fibrinogen concentrate within 45 minutes of admission to hospital to adult trauma patients with severe bleeding.

Who can participate?
People aged at least 16 with severe bleeding and shock.

What does the study involve?
Patients are randomly allocated to one of two groups. Those in group 1 are given 6g of fibrinogen concentrate within 45 minutes of being admitted to hospital, in addition to standard major haemorrhage therapy. Those in group 2 are given a placebo in additional to the standard major haemorrhage therapy. The effects of the two treatment regimens are then compared, focusing in particular on differences in blood test results and on clinical outcomes such as bleeding and organ failure.

What are the possible benefits and risks of participating?
The potential benefits associated of this study include early stopping of major bleeding which may lead to reduced need for transfusions of red cells, plasma or platelets. This, in turn, may lead to improved clinical outcomes such as reduced stays on intensive care, or total in hospital stay. It may have an effect on reducing the number of deaths, but this is not yet known. The theoretical risk of giving higher dose fibrinogen is to cause an increased chance of thromboembolism (blood clot) both in the vein (such as a pulmonary embolism or deep venous thrombosis) or in the artery (such as a heart attack or a stroke).

Where is the study run from?
The John Radcliffe Hospital (lead centre), the Royal London Hospital, Southampton General Hospital and the Edinburgh Royal Infirmary (UK)

When is the study starting and how long is it expected to run for?

Primary outcome measures

1. Feasibility of administering fibrinogen concentrate within 45 minutes of admission.
2. Proportion of patients with at least one Clauss fibrinogen level ≥ 2 g/L during active haemorrhage.

Secondary outcome measures

1. Transfusion volumes, in numbers of units, for red cells, plasma, platelets and cryoprecipitate at 3, 6 hours and 24 hours from admission
2. Clauss fibrinogen levels at day 7 post randomisation
3. ROTEM measures of coagulation (EXTEM and FIBTEM, where available) to day 7 post randomisation
4. Thrombotic events: clinically apparent venous thromboembolism (DVT, PE) and arterial events (MI, stroke) to day 28 from randomisation
5. Duration of and/or requirement for organ support to day 28 from admission, as defined by the CTCOFR score
6. All-cause mortality (including death from bleeding) at 3, 6 and 24 hours and up to day 28 from admission. Mortality at 1 year by longer term follow up
7. Hospital stay including ICU/HDU stay
8. Quality of life at 28 day from admission
9. Proportion of patients achieving haemostasis at 3 hours from admission (defined using a trial specific haemorrhage assessment tool)

Results and Publications

Publication and dissemination plan

The final study data set will be analysed and results published as soon as possible following completion of study follow up, final data checks and database lock. Individual Clinicians must not publish data concerning their patients that are directly relevant to questions posed by the trial until the Trial Management Group has published its report. The Trial Management Group will form the basis of the Writing Committee and will advise on the nature of publications.
