COVID-19 is a respiratory disease caused by a novel coronavirus (SARS-CoV-2) and causes substantial morbidity and mortality. There is currently no vaccine to prevent Covid-19 or infection with SARS-CoV-2 or therapeutic agent to treat COVID-19.
This protocol CORIMUNO19-COAG will evaluate the efficacy and safety of active anticoagulation using heparin: Tinzaparin (INNOHEP®) or unfractionated heparin (Calciparine®, Héparine Sodique Choay®) in COVID-19 patients hospitalized in conventional or intensive care units.
It will use a phase 2 randomized open-label multicentre clinical trial, where patients will be randomly allocated to anticoagulation versus Standard of Care.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
COVID19 Pneumonia | Drug: Tinzaparin or unfractionated heparin | Phase 2 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 808 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Randomized clinical trial with 2 parallels arms, 1:1, stratified on disease severity (ventilation or not) |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |
Official Title: | Cohort Multiple Randomized Controlled Trials Open-label of Immune Modulatory Drugs and Other Treatments in COVID-19 Patients CORIMUNO-COAG Trial |
Estimated Study Start Date : | April 20, 2020 |
Estimated Primary Completion Date : | July 31, 2020 |
Estimated Study Completion Date : | September 30, 2020 |

Arm | Intervention/treatment |
---|---|
Experimental: Active Coagulation |
Drug: Tinzaparin or unfractionated heparin
Tinzaparin INNOHEP ® 175 IU/kg/24h for 14 days if creatinine clearance Cockcroft ≥ 20mL/min, Otherwise unfractionated heparin (Calciparine®, Héparine Sodique Choay®) subcutaneously or intravenous with an anti-Xa target between 0.5 and 0.7 IU/mL for 14 days |
No Intervention: Standard of Care
Control patients will receive the best standard of care and a subcutaneous preventive anticoagulation for at least 14 days with enoxaparin 4000 IU/24h, tinzaparin 3500 IU/24h or dalteparin 5000 IU/24h if creatinine clearance (Cockcroft) ≥ 30mL/min or unfractionated heparin 5000 IU/12h if creatinine clearance < 30mL/min.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- group 1 : patients not requiring ICU at admission with mild disease to severe pneumopathy according to The Who Criteria of severity of COVID pneumopathy, and with symptom onset before 14 days, with need for oxygen but No non-invasive ventilation (NIV) or High flow
-
group 2 :
- Respiratory failure AND requiring mechanical ventilation
- WHO progression scale ≥ 6
- No do-not-resuscitate order (DNR order)
Exclusion Criteria:
-
Patients with contraindications to anticoagulation
- Congenital hemorrhagic disorders
- Hypersensitivity to tinzaparin or UHF or to any of the excipients
- Current or history of immune-mediated heparin-induced thrombocytopenia
- Active major haemorrhage or conditions predisposing to major haemorrhage. Major haemorrhage is defined as fulfilling any one of these three criteria: a) occurs in a critical area or organ (e.g. intracranial, intraspinal, intraocular, retroperitoneal, intra-articular or pericardial, intra-uterine or intramuscular with compartment syndrome), b) causes a fall in haemoglobin level of 20 g/L (1.24 mmol/L) or more, or c) leads to transfusion of 2 or more units of whole blood or red blood cells.
- Septic endocarditis
- Patients with need for anticoagulant therapy. For example: atrial fibrillation, venous thromboembolism, mechanical valve, etc.
