An Experiment to Evaluate the Safety of agenT-797 in COVID-19 Patients With Severe Difficulty Breathing.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Brief Summary:
A Phase 1 Study of AGENT-797 to treat moderate to severe acute respiratory syndrome in COVID-19 patients.

Condition or disease Intervention/treatment Phase
Respiratory Distress Syndrome, Adult Drug: agenT-797 Phase 1

Detailed Description:

This is a Phase 1 study to evaluate the safety and efficacy of agenT-797, an unmodified, allogeneic iNKT therapy, in patients with coronavirus disease 2019 (COVID-19), requiring mechanical ventilation, and with moderate to severe 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 patients will receive a single infusion of agent-797. Patients 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 patients in the Expansion Cohort.

Details of the analyses will be described in a statistical analysis plan.

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.

Arm Intervention/treatment
Experimental: Dosage and Cohorts

Cohort 1 100 × 106 iNKT Cohort 2 300 × 106 iNKT Cohort 3 1000 × 106 iNKT

Dosage Frequency and Mode of Administration: agenT-797 will be administered to hospitalized patients as a single IV infusion.

Drug: agenT-797
agenT-797 is an off-the shelf cell therapy consisting of ≥ 95% allogeneic human unmodified iNKT isolated from 1 healthy donor mononuclear cell apheresis unit and expanded ex-vivo.

Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [ Time Frame: 6 months ]
    Number and severity of adverse events (AEs)

  2. Number of Dose Limiting Toxicities [ Time Frame: 6 months ]
    Number of Dose Limiting Toxicities

Secondary Outcome Measures :
  1. To assess time to improvement in pulmonary function. [ Time Frame: 30 days ]

    Time to extubation.

    Assessment of ventilator-free days.

    Oxygenation improvement as per Berlin definition (ARDS 2012).

    Supportive interventions used (e.g. use of prone ventilation, paralytics, pulmonary vasodilators, and other interventions affecting oxygenation).

  2. Amount of virus detected in respiratory tract samples. [ Time Frame: 30 days ]
    Decay in quantitative viral burden from upper and lower respiratory tract samples collected.

  3. To assess longevity of agenT-797 infusion. [ Time Frame: 30 days ]
    Persistence of allogeneic invariant natural killer T cells (iNKT) non-transduced cells.
