NCT03715348

Brief Summary

The PROPHESY trial is a single centre pilot trial investigating Fresh Frozen Plasma (FFP) or Prothrombin Complex Concentrate (PCC) treatment for patients who are bleeding during cardiac surgery, and who are NOT receiving a vitamin K antagonist agent (e.g. warfarin). This pilot study will investigate the feasibility of delivering the different components of the trial, so that investigators can determine if it's feasible to move to a future large trial that will aim to compare the efficacy and safety of FFP versus PCC in adult patients who are actively bleeding during cardiac surgery.

Outcome Measures

Primary Outcomes (1)

  • Recruitment rate

    Proportion of eligible patients who consent to the study Proportion of patients who have consented and who bleed within 24 hours and who require FFP transfusion.

    Within 24 hours of surgery

Secondary Outcomes (4)

  • Delivery of different components of the trial to see if a larger trial is feasible

    Collected at 90 days or death, whichever occurs first

  • To compare the impact of FFP and PCC on the haemostatic capacity of bleeding patients after cardiac surgery

    Within 24 hours of surgery

  • Qualitative research involving completion of a Delphi survey to apprise the management and conduct of a larger trial

    Completed over a 4 month period during the study follow-up stage

  • Qualitative research involving interviews of patients and healthcare professionals involved in PROPHESY to apprise the management and conduct of a larger trial

    By the 90 days end of study visit

Study Arms (2)

Fresh Frozen Plasma (FFP)

ACTIVE COMPARATOR

Patients randomised to the comparator arm will receive Fresh Frozen Plasma (FFP) FFP will be provide as a solution for intravenous administration, once thawed. The dose of the FFP will be \~ 15 mL/kg. Subjects may receive multiple doses of FFP as required if bleeding continues, as per usual care

Biological: Fresh Frozen Plasma

Prothrombin Complex Concentrate (PCC)

EXPERIMENTAL

Patients randomised to the experimental arm will receive PCC at \~15 IU/kg. PCC will be reconstituted into a solution for intravenous administration. Subjects will receive a single dose of PCC, and if bleeding continues, standard treatment will be administered

Drug: Prothrombin Complex Concentrate (PCC)

Interventions

PCC is a blood product produced through pooling of thousands of human plasmas, which is then treated to inactivate enveloped viruses. From the pooled plasma, vitamin K dependent clotting factors (factors II, VII, IX and X, and protein C and protein S), are selected to produce the concentrated form called PCC.

Prothrombin Complex Concentrate (PCC)

Fresh Frozen Plasma a blood component manufactured from whole blood collection.
