About

The primary object of this clinical study is to investigate the efficacy and the safety of NOA-001 in patients with ARDS (ARDS caused by Non-COVID-19 or COVID-19).

Full description

(ARDS caused by Non-COVID-19 cohort): The objectives of this clinical study is to investigate the efficacy and safety of NOA-001 in patients with ARDS caused by Non-COVID-19. The number of patients enrolled is 30 (20 patients in the NOA-001 group and 10 patients in the standard therapy group).

(ARDS caused by COVID-19 cohort): The objectives of this clinical study is to investigate the efficacy and the safety of NOA-001 in patients with ARDS caused by COVID-19. The number of patients enrolled is 15 (in the NOA-001 group only).

Enrollment: 45 estimated patients

Sex: All

Ages: 16+ years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

(ARDS caused by Non-COVID-19 cohort)

Inclusion Criteria:

At Informed Consent

1. Patients with ARDS confirmed by the Berlin definition based on the following diagnostic criteria (a)-(d):

   1. Patients within 7 days from invasion or exacerbation of respiratory symptoms or acute onset of ARDS.
   2. Patients with respiratory failure not fully explained by cardiac failure or fluid overload; Need objective assessment (e. g., echo-cardiography) to exclude hydrostatic edema if no risk factor present
   3. Patients with bilateral opacities not fully explained by effusions, lobar/ lung collapse, or nodules on chest X-ray or CT scan
   4. Patients with PaO2/ FiO2 ratio ≤ 300 mmHg (PEEP ≥ 5 cmH2O)

2. Patients who are intubated and mechanically ventilated

3. Patients who can be enrolled in the study within 96 hours after initiation of mechanical ventilation

4. Patients aged ≥ 16 years at informed consent (Signed informed consent form from legally acceptable representative must be available if patient is aged < 20 years)

At Enrollment

1. Patients with PaO2/ FiO2 ratio ≥ 50 mmHg and ≤ 200 mmHg (PEEP ≥ 5 cmH2O)

7. Patients who have burns in excess of 15% total body surface area
8. Patients after resuscitation from cardiac arrest
9. Patients with a history of hypersensitivity to the anticoagulants (Heparin or Nafamostat mesylate)
10. Patients who have received cytapheresis, blood purification therapy with cytokine adsorbing devices or endotoxin removal therapy within 7 days prior to informed consent
11. Patients with pregnancy or lactating
12. Patients tested positive for COVID-19

4. Patients who have received cytapheresis, blood purification therapy with cytokine adsorbing devices or endotoxin removal therapy between informed consent and enrollment
5. Patients whose life expectancy is ≤ 24 hours after enrollment
6. Patients after resuscitation from cardiac arrest between informed consent and enrollment
7. Patients tested positive for COVID-19 between informed consent and enrollment
