20A 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.
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.
agenT-797 is an off-the-shelf cell therapy consisting of ≥ 95% allogeneic human unmodified iNKT cells isolated from 1 healthy donor mononuclear cell apheresis unit and expanded ex vivo.
Cohort 1: 100 × 10^6 iNKT cells; Cohort 2: 300 × 10^6 iNKT cells; Cohorts 3 to 4: 1000 × 10^6 iNKT cells Dosage Frequency and Mode of Administration: agenT-797 will be administered to hospitalized participants as a single intravenous infusion.
