Clinical Trial Summary

A Phase 1/2 study of agenT-797 to treat moderate to severe acute respiratory distress syndrome (ARDS) secondary to acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or influenza.

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.
