Brief summary
The purpose of this study is to test the safety and effectiveness of individually or simultaneously blocking IL-6 and IL-1 versus standard of care on blood oxygenation and systemic cytokine release syndrome in patients with COVID-19 coronavirus infection and acute hypoxic respiratory failure and systemic cytokine release syndrome
Detailed description
There are currently no treatments directed at halting the cytokine storm and acute lung injury to stop the progression from manageable hypoxia to frank respiratory failure and ARDS in patients with COVID-19 infection. Preventing progression from early acute hypoxia and cytokine release syndrome to frank hypoxic respiratory failure and ARDS could have a huge impact on the foreseeable overflow of the ICU units. In ventilated patients, preventing the onset of ARDS, or shortening ICU stay could also be crucial in this regard. The clinical status after 15 days treatment is evaluated to measure the effectiveness of tocilizumab, tocilizumab and anakinra, siltuximab, siltuximab and anakinra and anakinra on restoring lung homeostasis,using single IV injection (siltuximab or tocilizumab) combined or not with daily subcutaneous injections of anakinra until 28 days or hospital discharge, whichever is first. During the treatment period, daily clinical assesments of severity, daily laboratory check-up, measurements of oxygen saturation (pulse oximetry) in relation to FiO2, regular arterial blood gas measurements, regular chest X-rays, chest CT scans on indication will be performed.
Interventions
Usual Care
Anakinra will be given as a daily subcutaneous injection of 100 mg for 28 days or until hospital discharge, whichever is first
Siltuximab will be given via single IV infusion at a dose of 11 mg/kg
Tocilizumab will be given via single IV infusion at a dose of 8 mg/kg with a maximum infusion of 800 mg/injection

Eligibility
Inclusion criteria
* Recent ( ≥ 6 days of flu-like symptoms or malaise yet ≤16 days of flu-like symptoms or malaise prior to randomization) infection with COVID-19. * Confident COVID-19 diagnosis confirmed by antigen detection test and/or PCR and/or positive serology, or any emerging and validated diagnostic laboratory test for COVID-19 within this period. * In some patients, it may be impossible to get a confident laboratory confirmation of COVID-19 diagnosis after 24h of hospital admission because viral load is low and/or problems with diagnostic sensitivity. In those cases, in absence of an alternative diagnosis, and with highly suspect bilateral ground glass opacities on recent (\<24h) chest-CT scan (confirmed by a radiologist and pulmonary physician as probable COVID-19), and a typical clinical and chemical diagnosis with signs of cytokine release syndrome, a patient can be enrolled as probable COVID-19 infected. In all cases, this needs confirmation by later seroconversion. * Presence of hypoxia defined as PaO2/FiO2 below 350 while breathing room air in upright position or PaO2/FiO2 below 280 on supplemental oxygen and immediately requiring high flow oxygen device or mechanical ventilation * signs of cytokine release syndrome defined as ANY of the following: 1. serum ferritin concentration \>1000 mcg/L and rising since last 24h 2. single ferritin above 2000 mcg/L in patients requiring immediate high flow oxygen device or mechanical ventilation 3. lymphopenia defined as \<800 lymphocytes/microliter) and two of the following extra criteria * Ferritin \> 700 mcg/L and rising since last 24h * increased LDH (above 300 IU/L) and rising last 24h * D-Dimers \> 1000 ng/mL and rising since last 24h * CRP above 70mg/L and rising since last 24h and absence of bacterial infection * if three of the above are present at admission, no need to document 24h rise * Chest X-ray or CT scan showing bilateral infiltrates within last 2 days * Admitted to specialized COVID-19 ward or an ICU ward taking care of COVID-19 patients * Age ≥ 18yrs * Male or Female * Willing and able to provide informed consent or legal representative willing to provide informed consent
Exclusion criteria
* Patients with known history of serious allergic reactions, including anaphylaxis, to any of the study medications, or any component of the product. * mechanical ventilation \> 24 h at Randomization * Patient on ECMO at time of screening * clinical frailty scale above 3 (This frailty score is the patient status before first symptoms of COVID-19 episode.) * active bacterial or fungal infection * unlikely to survive beyond 48h * neutrophil count below 1500 cells/microliter * platelets below 50.000/microliter * Patients enrolled in another investigational drug study * patients on high dose systemic steroids (\> 20 mg methylprednisolone or equivalent) for COVID-19 unrelated disorder * patients on immunosuppressant or immunomodulatory drugs * patients on current anti-IL1 or anti-IL6 treatment * signs of active tuberculosis * serum transaminase levels \>5 times upper limit of normal * bowel perforation or diverticulitis * pregnant or breastfeeding females (all female subjects deemed of childbearing potential by the investigator must have negative pregnancy test at screening) * Women of childbearing potential must have a negative serum pregnancy test pre-dose on day 1. Woùmen of childbearing potential must consistently and correctly use (during the entire treatment period and 3 months after last reatment) 1 highly effective method for contraception.
