Not Applicable

Recruiting

• Conditions: Acute Respiratory Distress Syndrome
• Interventions: Device: NOA-001

• Registration Number: NCT04804943
• Lead Sponsor: Toray Industries, Inc

Brief Summary

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).

Detailed 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).

   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

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)
