A Clinical Trial to Evaluate agenT-797 Plus Standard of Care in Participants With Severe Pneumonia With Moderate to Severe Acute Hypoxemic Respiratory Failure

May 22, 2026 updated by: MiNK Therapeutics

Phase 2 Adaptive Randomized, Placebo -Controlled Trial of agenT-797 + Standard of Care Vs. Placebo + Standard of Care in Severe Pneumonia With Moderate to Severe Acute Hypoxemic Respiratory Failure (AHRF) By Global ARDS Criteria

This clinical trial will evaluate the efficacy and safety of a single intravenous dose of agenT-797 administered in addition to standard of care (SOC), compared with placebo plus SOC, in reducing short-term mortality in adult participants with severe pneumonia and moderate to severe AHRF. All participants will receive SOC management for severe pneumonia and acute respiratory distress syndrome (ARDS).

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This trial will be conducted in 2 parts (Run-in Phase; Phase 2). The Run-in Phase is designed to characterize the baseline population of the site, where participants will receive open-label agenT-797 plus SOC. After completion of the Run-in Phase, participants will be enrolled and randomized to receive either agenT-797 plus SOC or placebo plus SOC during the double-blinded Phase 2.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Key Inclusion Criteria:

  • Admission to an intensive care unit (ICU) with severe pneumonia of any etiology (viral, bacterial, fungal, or mixed), with and without trauma based on clinical suspicion
  • Acute hypoxemic respiratory failure (AHRF)
  • Evidence of moderate to severe acute respiratory distress syndrome (ARDS) based on Global ARDS criteria
  • Onset of severe pneumonia with AHRF ≤7 days prior to informed consent

Key Exclusion Criteria:

  • More than two vasopressors to maintain a mean arterial pressure ≥65 millimeters of mercury at the time of informed consent
  • Pregnancy or breastfeeding
  • History of cytokine release syndrome, as documented in the medical record or reported by the participant, legally authorized representative, or close relative
