About this study
The overall objective of the study is to determine the therapeutic effect and tolerance of Sarilumab in patients with moderate, severe pneumonia or critical pneumonia associated with Coronavirus disease 2019 (COVID-19). Sarilumab is a human IgG1 monoclonal antibody that binds specifically to both soluble and membrane-bound IL-6Rs (sIL-6Rα and mIL-6Rα) and has been shown to inhibit IL-6-mediated signaling through these receptors. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering Sarilumab administration to patients enrolled in the CORIMUNO-19 cohort. Sarilumab will be administered to consenting adult patients hospitalized with COVID-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 Sarilumab will receive standard of care. Outcomes of Sarilumab-treated patients will be compared with outcomes of standard of care-treated patients as well as with outcomes of patients treated with other immune modulators.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With WHO Clinical Progression Scale > 5 at Day 4 -- Severe COVID Population (WHO Clinical Progression Scale =5 at Baseline)
Percentage of participants who has died or needed non-invasive or mechanical ventilation by day 4 (WHO clinical progression scale > 5). A patient with new do-not-resuscitate 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
Measured: 4 days
Percentage of Participants With Non-invasive Ventilation, Mechanical Ventilation or Death at Day 14 (WHO Clinical Progression Scale =5 at Baseline)
Survival without needs of ventilator utilization (including non invasive ventilation and high flow) at day 14. Percentage of non-invasive ventilation, mechanical ventilation or death. Thus, events considered are needing ventilator utilization (mechanical or non-invasive ventilation including high flow oxygen), or death. New do-not-resuscitate (DNR) order (if given after the inclusion of the patient) will be considered as an event at the date of the DNR.
Measured: Day 1 to Day 14
Percentage of Participants With no Improvement in WHO Clinical Progression Scale at Day 4 -- Critical COVID Population ( WHO Clinical Progression Scale >5 at Baseline)
Results are presented as the percentage not improved, so that an effective treatment would be associated with a decrease in percentage
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
Measured: 4 days
Cumulative Incidence (Percentage of Participants) With Successful Tracheal Extubation at Day 14 -- Critical COVID Population (WHO Clinical Progression Scale >5 at Baseline)
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 Non Invasive Ventilation or high flow (for > 48h) if they were included under oxygen by Non Invasive Ventilation or High flow (score 6) and remained without intubation. Death or new do-not-resuscitate order (if given after the inclusion of the patient) will be considered as a competing event.
Measured: Day 1 to Day 14

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The overall objective of the study is to determine the therapeutic effect and tolerance of Sarilumab in patients with moderate, severe pneumonia or critical pneumonia associated with Coronavirus disease 2019 (COVID-19). Sarilumab is a human IgG1 monoclonal antibody that binds specifically to both soluble and membrane-bound IL-6Rs (sIL-6Rα and mIL-6Rα) and has been shown to inhibit IL-6-mediated signaling through these receptors. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering Sarilumab administration to patients enrolled in the CORIMUNO-19 cohort. Sarilumab will be administered to consenting adult patients hospitalized with COVID-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 Sarilumab will receive standard of care. Outcomes of Sarilumab-treated patients will be compared with outcomes of standard of care-treated patients as well as with outcomes of patients treated with other immune modulators.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Sarilumab in people with Corona Virus Infection, run by Assistance Publique - Hôpitaux de Paris at 4 sites in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 14 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Jun 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
