- Determining the highest-tolerated & safety-tested AT-100 dose [ Time Frame: From time of initial AT-100 dosing until the end of the dosing period, up to 7 days ]Dose escalation of AT-100 will occur to determine the maximum dose (in mg) that produces no significant Dose Limiting Toxicities or dose-related Adverse Events (AEs).
- Reduction in mechanical ventilation [ Time Frame: From mechanical ventilation initiation up to Day 28 ]Days on mechanical ventilation.
- Mortality [ Time Frame: Through study completion, up to Day 90 ]Incidence of death.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- The subject is an adult ≥18 years of age.
- The subject has documented, laboratory-confirmed SARS-CoV-2 infection within 2 weeks prior to enrollment.
- The subject has severe SARS-CoV-2 infection requiring intubation and mechanical ventilation.
- The subject has been receiving mechanical ventilation for <72 hours.
- The subject is receiving mechanical ventilation due to respiratory disease that is primarily due to SARS-CoV-2 infection.
- The subject, or legally authorized representative if acting on the subject's behalf, is able to provide informed consent.
Exclusion Criteria:
- The subject refuses to participate, or the subject's legally authorized representative acting on the subject's behalf refuses the subject's participation.
- The subject is pregnant or breastfeeding.
- The subject is anticipated to be transferred to another hospital that is not a study site within 36 hours of enrollment.
- The subject has received or is receiving extracorporeal membrane oxygenation (ECMO) treatment for COVID-19 treatment.
- The subject has Human Immunodeficiency virus (HIV) under highly active antiretroviral therapy (HAART).
- The subject has cancer and is receiving chemotherapy treatment at any time during trial duration, or has received chemotherapy treatment within 30 days of trial enrollment.
- The subject has a prior history of lung transplant, lobectomy, or other significant lung surgeries that would indicate an already compromised lung.
- The subject has known pulmonary air leaks, such as pneumothorax and pneumomediastinum.
- Concurrent enrollment in an investigational product, device, or treatment trial with exception of Remdesivir whether part of a clinical trial or standard-of-care management.
- The subject has a known allergy, sensitivity, or contraindication to any component of the test article (AT-100).
- The subject has any active do not resuscitate (DNR)-Comfort Care (CC) order in place. Subjects with an active DNR-Comfort Care Arrest (CCA) are not excluded.
- The subject's intubation, re-intubation, or remaining on intubation is not per clinical standard-of-care and is solely for the purposes of administration of study drug.
- The subject has any condition or is in a situation in which, in the Investigator's judgement, puts the subject at significant risk, could confound the trial results, or may significantly interfere with the subject's trial participation.
