Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Diagnosed with coronavirus disease 2019 (COVID-19) and confirmed severe acute respiratory syndrome coronavirus 2 (SARS-coV-2) viral infection
* Severe or critical COVID-19, or National Institute of Allergy and Infectious Diseases (NIAID) 8-point ordinal score 2, 3 or 4 (Scale 2: requiring invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); Scale 3: non-invasive ventilation or high flow oxygen devices; Scale 4: supplemental oxygen support; a peripheral capillary oxygen saturation (SpO2) \</= 94% or tachypnea (respiratory rate \>/= 24 breaths/min). Intubation should be within 7 days

Exclusion Criteria

* Participants who are pregnant, breastfeeding, or have a positive pregnancy test result before enrollment
* Participants previously enrolled in the efprezimod alfa study
* Intubation for invasive mechanical ventilation is over 7 days
* Documented acute renal or hepatic failure
* The investigator believes that participating in the trial is not in the best interests of the participant, or the investigator considers unsuitable for enrollment (such as unpredictable risks or subject compliance issues)
