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

A Phase 1 Study of agenT-797 to Treat Moderate to Severe Acute Respiratory Syndrome in COVID-19 Patients

A Phase 1 study of agenT-797 to treat moderate to severe acute respiratory syndrome in Coronavirus disease 2019 (COVID-19) participants.

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.

Inclusion Criteria:

• Participants, or duly appointed health care proxy with the authority to consent, must consent to placement of a central venous access line for the administration of agenT-797.

Exclusion Criteria:

• Currently participating and receiving study therapy of an investigational agent that is not registered for any other indication. Note: Participants may receive the standard of care for SARS-CoV-2 infection as per institutional practices.
• Presence of comorbidities limiting expected survival of <1 month.
• Any comorbidity which in the opinion of the investigator may preclude/confound study required safety and efficacy assessments.
