Trial summary
The aim of this research is to measure fibrinolytic activity in neoplastic pathologies in order to provide preliminary data on which to base a future, larger-scale study to determine predictive markers of complication in order to improve patient management. Read more about this study

About this study
The aim of this research is to measure fibrinolytic activity in neoplastic pathologies in order to provide preliminary data on which to base a future, larger-scale study to determine predictive markers of complication in order to improve patient management.
Primary purpose: measure plasminogen concentration on day 1 in subjects diagnosed with malignant hematological disease, solid tumors, or septic shock, with coagulopathy.

Secondary purpose:
- Estimate the difference in plasminogen concentration at D1 in patients with coagulopathy between subjects with a diagnosis of haematological malignancy and those with solid tumor
- Estimate the difference in plasminogen concentration at D1 in patients with coagulopathy between subjects with a diagnosis of haematological malignancy and those with septic shock
- Estimate the difference in plasminogen concentration on Day 1 in patients with coagulopathy between subjects with a diagnosis of solid tumor and those with septic shock.
In the 3 groups, subjects with a diagnosis of haematological malignancy, solid tumor, septic shock, presenting with coagulopathy:
- Evaluate the correlation between the concentration of circulating plasminogen active on Day 1 and the occurrence of a bleeding complication within 28 days of admission to critical care.
- Evaluate the correlation between the concentration of circulating plasminogen active on Day 1 and the occurrence of a thrombotic complication, within 28 days of admission to critical care.
- Evaluate the predictive performance of circulating active plasminogen concentration on Day 1 in the need for extra renal purification within 28 days of admission to critical care.
- Estimate the differences at each time point (D1, D3, D7) in haemostasis markers and markers of fibrinolytic activity and its regulation.
Assess the link between fibrinolytic activity and :
- The diagnosis of disseminated intravascular coagulation (DIC),
- The risk of haemorrhage
- Risk of organ failures
- Thrombotic risk
- Risk of organ failure
- Neutrophile activation and circulating NETs levels
- Conditions
- Hematologic Neoplasms, Solid Tumor Metastatic Cancer Advanced Cancer, Disseminated Intravascular Coagulation
- Being tested
- An additional volume of blood will be drawn as part of routine follow-up care

- Hematologic Neoplasms, Disseminated Intravascular Coagulation
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
An additional volume of blood will be drawn as part of routine follow-up careBiological
The biological samples collected correspond to blood samples taken from venous or arterial catheters inserted at the time of admission as part of routine care. The total volume of blood collected at D1 and D7 was 18.5 mL (3 x 4 mL citrate tubes, 1 x 4 mL EDTA tube and 1 x 2.5 mL Paxgene tube). The volume of blood drawn at D3 was 16 mL (3 x 4 mL citrated tubes, one 4 mL EDTA tube).
Samples are immediately analyzed in the hematology/hemostasis laboratory for NETs and hemostasis, with the remaining portion of the tube centrifuged before plasma is frozen at -80°C for plasma analysis. The Paxgene tube can be used for non-identifying genetic analyses.
