Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age above 18 years.

  • Must understand and voluntarily sign an Informed Consent for study participation obtained prior to undergoing any study-specific procedures
  • Diagnosed as COVID-19 based upon SARS-CoV-2 RT-PCR test positive

  • Clinically active malignant disease
  • Subjects who are receiving ECMO and CRRT currently
  • History of known pulmonary embolism or known secondary anti-phospholipid syndrome
  • Known or suspected hypersensitivity to any components used to culture the AdMSCs, e.g. BSA and sulfur containing products (e.g., DMSO)

  • Major trauma or surgery within 14 days of study treatment start
  • Mental condition rendering the subject (or the subject's legally acceptable representative[s]) unable to understand the nature, scope and possible consequences of the study
  • Alcohol, drug, or medication abuse within one year prior to study treatment start
  • Any condition that, in the Investigator's opinion, is likely to interfere with evaluation of the AdMSC therapy or satisfactory conduct of the study
  • Irreversible severe end organ failure, such as heart failure/attack, stroke, liver and renal failure due to other disease conditions

    Study Group

    Control Group

    Arm Description

    Each subject receives three separate doses of 200 million allogeneic adipose-derived mesenchymal stem cells via intravenously infusion on days 0, 3, and 6 with a total of 600 million AdMSCs during 7 days in addition to their standard of care.

    The control group will receive placebo infusion on day 0, 3 and 6 along with standard of care.

    Outcomes

    Primary Outcome Measures

    Safety of AdMSC injection will be evaluated by assessment of the frequency and nature of adverse events occurring during the study based on the rate of all AdMSC-associated adverse events (AEs) in all subjects.
