Inclusion Criteria

  • Voluntarily agree to participate and ability to provide informed consent or have duly appointed health care proxy with the authority to consent. - Confirmed diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection by polymerase chain reaction test or equivalent approved test. - Inpatient hospitalization. - Evidence of SARS-CoV-2 infection with the diagnosis of moderate to severe ARDS per Berlin definition, no more than 2 weeks prior to study enrollment. - 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

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. - Clinically significant cardiomyopathy. - Receipt of non-oncology vaccines containing live virus for prevention of infectious diseases within 4 weeks prior to first dose of study treatment. - Known hypersensitivity to natural killer cells or their preservation solution. - Active systemic bacterial or fungal infection or viral co-infection. - Legally incapacitated or has limited legal capacity. - Pregnant or lactating women.

Detailed Description

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.
