NCT04378712

Brief Summary

This was a randomized, multi-center, open-label clinical trial. Eligible patients were recruited from seven hospitals in China. On the basis of standard-of-care, patients in treatment group inhaled H2-O2 (66% hydrogen; 33% oxygen) at 3 L/min via nasal cannula by using the Hydrogen/Oxygen Generator (model AMS-H-03, Shanghai Asclepius Meditech Co., Ltd., China) until discharge. Patients in control group received standard-of-care (consisting of oxygen therapy) alone until discharge.

Intervention Group

EXPERIMENTAL

H2-O2 (66% hydrogen; 33% oxygen) inhalation. Patients in treatment group inhaled H2-O2 (66% hydrogen; 33% oxygen) at 3 L/min via nasal cannula by using the Hydrogen/Oxygen Generator (model AMS-H-03, Shanghai Asclepius Meditech Co., Ltd., China) until discharge.

Device: Hydrogen Oxygen Generator with NebulizerOther: Standard-of-care

Control Group

OTHER

Usual care referred to the standard-of-care (including oxygen therapy) recommended by Chinese National Health Commission.

Other: Standard-of-care

Interventions

Patients in treatment group inhaled H2-O2 (66% hydrogen; 33% oxygen) at 3 L/min via nasal cannula by using the Hydrogen/Oxygen Generator (model AMS-H-03, Shanghai Asclepius Meditech Co., Ltd., China) until discharge.

Intervention Group

Standard-of-care consisted of the supportive therapies (including oxygen therapy) recommended by the Chinese National Health Commission

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with lab-confirmed Covid-19 aged 18 to 75 years.
  • Had dyspnea both on hospital admission and at enrollment.
  • The patients volunteered to participate in this study and signed the informed consent

You may not qualify if:

  • Have other systemic diseases other than COVID-19 -- a disease that, according to the investigator's judgment, might increase the risk of developing adverse outcomes or affect the outcome measures after participation in the study.
  • Women who are pregnant or breastfeeding or plan to be pregnant during the study.
  • Subjects with one of the following respiratory diseases:
  • Subjects in critical or unstable conditions. Critical (meeting any of the following symptoms): 1. Respiratory failure occurs and mechanical ventilation is needed; 2. Shock occurs; 3. Other organ failure, ICU monitoring and treatment is needed.
  • Having immunosuppressive diseases (HIV), severe neurological disease affecting upper respiratory tract control, or other risk factors that the investigator believes can cause a significant risk of pneumonia in subjects.
  • Subjects with mental disorder and cognitive impairment.
  • Subjects who do not follow the study steps.
  • Patients with mental retardation, poor motivation, drug abuse (including drugs and alcohol) or other disease history restricting the effectiveness of informed consent in this study.
  • Use of antioxidants, including large doses of vitamin C and vitamin E.
  • Subjects who are not suitable for participation in this study in the judgment of investigator.
