CORIMUNO-19 – Tocilizumab Trial – TOCI (CORIMUNO-TOCI)

Overview

The overall objective of the study is to determine the therapeutic effect and tolerance of Tocizilumab in patients with moderate, severe pneumonia or critical pneumonia associated with Coronavirus disease 2019 (COVID-19). Tocilizumab (TCZ) is an anti-human IL-6 receptor monoclonal antibody that inhibits signal transduction by binding sIL-6R and mIL-6R. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering Tocilizumab administration to patients enrolled in the COVIMUNO-19 cohort. Tocilizumab will be administered to consenting adult patients hospitalized with CORVID-19 either diagnosed with moderate or severe pneumonia requiring no mechanical ventilation or critical pneumonia requiring mechanical ventilation. Patients who will chose not to receive Tocilizumab will receive standard of cares. Outcomes of Tocilizumab-treated patients will be compared with outcomes of standard of care treated patients as well as outcomes of patients treated with other immune modulators.

Clinical Trial Outcome Measures

Primary Measures

  • Survival without needs of ventilator utilization at day 14. Group 1
    • Time Frame: 14 days
    • Group 1. Survival without needs of ventilator utilization (including non invasive ventilation and high flow) at day 14. Thus, events considered are needing ventilator utilization (including Non Invasive Ventilation, NIV or high flow), or death. New DNR order (if given after the inclusion of the patient) will be considered as an event at the date of the DNR.
  • WHO progression scale <=5 at day 4. Group 1.
    • Time Frame: 4 days
    • Group 1. Proportion of patients alive without non-invasive ventilation of high low at day 4 (WHO progression scale ≤ 5). A patient with new DNR order at day 4 will be considered as with a score > 5. WHO progression scale: Uninfected; non viral RNA detected: 0 Asymptomatic; viral RNA detected: 1 Symptomatic; Independent: 2 Symptomatic; Assistance needed: 3 Hospitalized; No oxygen therapy: 4 Hospitalized; oxygen by mask or nasal prongs: 5 Hospitalized; oxygen by NIV or High flow: 6 Intubation and Mechanical ventilation, pO2/FIO2>=150 OR SpO2/FIO2>=200: 7 Mechanical ventilation, (pO2/FIO2<150 OR SpO2/FIO2<200) OR vasopressors (norepinephrine >0.3 microg/kg/min): 8 Mechanical ventilation, pO2/FIO2<150 AND vasopressors (norepinephrine >0.3 microg/kg/min), OR Dialysis OR ECMO: 9 Dead: 10
  • Cumulative incidence of successful tracheal extubation (defined as duration extubation > 48h) at day 14. Group 2.
    • Time Frame: 14 days
    • Group 2. Cumulative incidence of successful tracheal extubation (defined as duration extubation > 48h) at day 14 if patients have been intubated before day 14 ; or removal of NIV or high flow (for > 48h) if they were included under oxygen by NIV or High flow (score 6) and remained without intubation. Death or new DNR order (if given after the inclusion of the patient) will be considered as a competing event.
  • WHO progression scale at day 4. Group 2.
    • Time Frame: 4 days
    • Group 2 Early end point : proportion of patients with a decrease of WHO score of at least 1 point at day 4. WHO progression scale: Uninfected; non viral RNA detected: 0 Asymptomatic; viral RNA detected: 1 Symptomatic; Independent: 2 Symptomatic; Assistance needed: 3 Hospitalized; No oxygen therapy: 4 Hospitalized; oxygen by mask or nasal prongs: 5 Hospitalized; oxygen by NIV or High flow: 6 Intubation and Mechanical ventilation, pO2/FIO2>=150 OR SpO2/FIO2>=200: 7 Mechanical ventilation, (pO2/FIO2<150 OR SpO2/FIO2<200) OR vasopressors (norepinephrine >0.3 microg/kg/min): 8 Mechanical ventilation, pO2/FIO2<150 AND vasopressors (norepinephrine >0.3 microg/kg/min), OR Dialysis OR ECMO: 9 Dead: 10

Secondary Measures

  • WHO progression scale
    • Time Frame: 7 and 14 days
