-
To evaluate the effect of SAR443122 relative to the control arm on laboratory markers of severe COVID-19
-
To evaluate the effect of SAR443122 relative to the control arm on mortality
-
To evaluate the effect of SAR443122 relative to the control arm on need for thrombolytic therapy
-
To evaluate the effect of SAR443122 relative to the control arm on need for vasopressor treatment
-
To evaluate the safety of SAR443122 as compared to the control arm up to End of Study
-
To evaluate the effect of SAR443122 relative to the control arm on total duration without high flow supplemental oxygen requirements

Eligibility Criteria
Criteria
Inclusion criteria:
-
Participant must be ≥18 years and ≤80 years of age inclusive, at the time of signing the informed consent.
-
Hospitalized (or documentation of a plan to admit to the hospital if the participant is in an emergency department) with evidence of COVID-19 lung disease diagnosed by chest radiograph, chest computed tomography or chest auscultation (rales, crackles) and with severe disease defined as follows: The participant requires supplemental oxygen administered by nasal cannula, simple face mask, or other similar oxygen delivery device (ie, increase in oxygen requirement following SARS-CoV-2 infection).
-
SARS-CoV-2 infection confirmed by RT-PCR, or other commercial or public health assay in any specimen, within 3 weeks prior to randomization, and no alternative explanation for current clinical condition.
-
At time of randomization, have demonstrated laboratory signs consistent with systemic inflammation.
-
Male and/or female participants, including women of childbearing potential (WOCBP).
-
Capable of giving signed informed consent.
Exclusion criteria:
-
In the opinion of the investigator, unlikely to survive after 48 hours, or unlikely to remain at the investigational site beyond 48 hours
-
Participants requiring use of invasive or non-invasive positive pressure ventilation at randomization.
-
Presence of significant liver enzyme abnormalities, thrombocytopenia or anemia at screening.
-
Any prior or concurrent use or plans to receive during the study period of immunomodulatory therapies (other than interventional drug) at screening.
-
Use of chronic systemic corticosteroids for a non-COVID-19-related condition in a dose higher than prednisone 10 mg or equivalent per day at screening.
-
Exclusion criteria related to tuberculosis (TB) and non-tuberculous mycobacterial (NTM) infections.
-
