Inpatient hospitalization 3. Evidence of SARS-CoV-2 infection with the diagnosis of moderate to severe ARDS secondary to SARS-CoV-2 or influenza per Berlin definition (ARDS 2012) 4. Participants, or study participant's duly appointed health care proxy with the authority to consent on behalf of the participant, must consent to placement of a central venous access line for the administration of agenT-797

Exclusion Criteria

Detailed Description

This is a Phase 1/2 study to evaluate the safety and potential efficacy of agenT-797, an unmodified, allogeneic invariant natural killer T (iNKT) cell therapy, in participants with moderate to severe ARDS secondary to SARS-CoV-2 or influenza, either with intubation or at high risk to be intubated, as determined using Berlin definition(s). Part 1 will employ a standard 3+3 dose escalation design of agenT-797. All participants will receive a single infusion of agenT-797. Participants will also receive other treatments and supportive care per discretion of the investigator. Once the maximum tolerated dose of agenT-797 has been cleared in Part 1, an Expansion Cohort will be opened. A safety monitoring committee will be established to assess safety and decide on escalation to next cohort and expansion dose, as well as any protocol modification to include less severe cases.
