Coagulopathy of COVID-19 afflicts approximately 20% of patients with severe COVID-19 and is associated with need for critical care and death. COVID-19 coagulopathy is characterized by elevated D-dimer, an indicator of fibrin formation and clot lysis, and a mildly prolonged prothrombin time, suggestive of coagulation consumption. To date, it seems that COVID-19 coagulopathy manifests with thromboembolism, thus anticoagulation may be of benefit. We propose to conduct a parallel pragmatic multi-centre open-label randomized controlled trial to determine the effect of therapeutic anticoagulation compared to standard care in hospitalized patients admitted for COVID-19 with an elevated D-dimer.
The primary aim of this study is to determine whether Camostat mesylate reduces SARS-COV-2 associated coagulopathy. Additional aims are to determine the effect of Camostat mesylate on SARS-COV-2 associated myocardial injury, to assess duration of hypoxia or intubation, to evaluate the length of intensive care unit and hospital stay, and assess mortality rates.
The prognosis of traumatized hemorrhages is correlated with the nature of transfusion therapy: a 50% reduction in mortality for an early and massive supply of plasma, and 20% for an early and massive supply of platelets. However, this strategy encounters logistical difficulties, particularly in a context of collective emergency (attacks). The use of whole blood, widely documented by the Armed Forces, improves the availability of plasma and platelets, and simplifies handling by the various actors in the chain. T-STORHM is a randomized, controlled, parallel clinical trial.This study tests non-inferiority of whole blood transfusion therapy in the management of coagulopathy in patients with acute traumatic hemorrhage.
To determine whether the coagulopathy associated with COVID-19 infection is driven by overactivation of the renin angiotensin system (RAS)
Randomized, controlled study conducted in hospitalized patients with severe COViD-19 pneumonia and coagulopathy not requiring invasive mechanical ventilation. Aim of this study is to assess whether high doses of Low Molecular Weight Heparin (LMWH) (ie. Enoxaparin 70 IU/kg twice daily) compared to standard prophylactic dose (ie, Enoxaparin 4000 IU once day) are: 1. More effective to prevent clinical worsening, defined as the occurrence of at least one of the following events, whichever comes first, during hospital stay: 1. Death 2. Acute Myocardial Infarction [AMI] 3. Objectively confirmed, symptomatic arterial or venous thromboembolism [TE] 4. Need for either non-invasive - Continuous Positive Airway Pressure (Cpap) or Non-Invasive Ventilation (NIV) - or invasive mechanical ventilation for patients who are in standard oxygen therapy by delivery interfaces at randomisation 5. Need for invasive mechanical ventilation for patients who are in non-invasive mechanical ventilation at randomisation 2. Similar in terms of major bleeding risk during hospital stay
In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well-controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.(1,2,3,4) In 2019 alone, the United States Food and Drug Administration (FDA) has issued approvals for twenty-four new therapies for congenital and acquired hematologic conditions.(5) In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.(6) With this increase in potential new therapies on the horizon, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. ATHN Transcends is a cohort study to determine the safety, effectiveness, and practice of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. The study consists of 7 cohorts with additional study "arms" and "modules" branching off from the cohorts. The overarching objective of this longitudinal, observational study is to characterize the safety, effectiveness and practice of treatments for all people with congenital and acquired hematologic disorders in the US. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.(7)

This prospective, randomized, open-label, multi-center interventional study is designed to compare the safety and efficacy of two LMWH dosing protocols in patients admitted to the University of Iowa Hospitals with COVID-19 who meet the modified ISTH Overt DIC criteria score ≥3. Patients will be randomized to standard prophylactic dose LMWH (standard of care arm) or intermediate-dose LMWH (intervention arm).
Increased D-dimers at admission of COVID-19 infected patients entering hospital due to a severe disease is a risk factor for death. Understanding this acquired coagulopathy is a prerequisite before specific interventional studies. The study investigators aim to apply a normalized and automated thrombin generation test (TGT), developed for testing the thrombotic risk (triggered by 5 pM Tissue Factor, with a purified thrombomodulin (TM) challenge) and to study its association with survival.
