NCT04336254

Brief Summary

This clinical trial is set out to evaluate the safety and efficacy of allogeneic human dental pulp mesenchymal stem cells in the treatment of severe pneumonia caused by COVID-19; to explore the effects of human dental pulp mesenchymal stem cells in the treatment of severe pneumonia of COVID-19 in terms of reducing mortality and improving clinical prognosis; and to discover a new therapeutic strategy for COVID-19 using allogeneic human dental pulp mesenchymal stem cells.

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

You may qualify if:

  • Aged 18-65 years;
  • Voluntarily participate in this clinical trial and sign off "informed consent form";
  • Diagnosed with severe pneumonia of COVID: respiratory distress, RR \>30 times / min; resting oxygen saturation of 93% or less; arterial partial pressure of oxygen / oxygen concentration 300mmHg; SARS-CoV-2 nucleic acid test was positive.
  • Chest imaging confirm COVID-19 featured lesions in lung.

You may not qualify if:

  • Receive any clinical trial drug treatment for COVID-2019 within 30 days before the screening assessment;
  • Severe liver disease (e.g., Child Pugh score \>=C or AST\> 5 times of the upper limit);
  • Patients with known severe renal insufficiency (estimated glomerular filtration rate \<=30mL / min/1.73 m2) or patients receiving continuous renal replacement therapy, hemodialysis, peritoneal dialysis;
  • Co-infection of HIV, hepatitis B, tuberculosis, influenza virus, adenovirus or other respiratory infection viruses;
  • Female patients who have no sexual protection in the last 30 days prior to the screening assessment;
  • Pregnant or lactating women or women using estrogen contraception;
  • Patients who are planning to become pregnant during the study period or within 6 months after the end of the study period;
  • Other conditions that the researchers consider not suitable for participating in this clinical trial.
