A Clinical Trial to Evaluate the Safety of agenT-797 in COVID-19 Participants With ARDS

This is a Phase 1 study to evaluate the safety and efficacy of agenT-797, an unmodified, allogeneic invariant natural killer T cells (iNKT) therapy, in participants with COVID-19, requiring mechanical ventilation, and with moderate to severe acute respiratory distress syndrome (ARDS) as determined by the Berlin definition. The study will be conducted in 2 parts. 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 principal investigator. Once the maximum tolerated dose of agenT-797 has been cleared in Part 1, Part 2 of the study will be opened and enroll eligible participants in the Expansion Cohort. 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.
