Brief Summary:
An open label clinical study to evaluate the safety and the efficacy of MesenCure, an allogeneic cell therapy product, for the treatment of the pulmonary manifestations in COVID19 patients

Condition or disease Intervention/treatment Phase
Covid19 Biological: MesenCure Phase 1 Phase 2

Detailed Description:

Primary endpoint: The IV administration of MesenCure is safe under the following conditions: in subjects hospitalized with COVID19 moderate to severe disease, defined upon clinical situation and radiologic findings.

Secondary endpoint: The IV administration of MesenCure is efficacious under the following conditions:

Clinical parameters: Health questionnaire, respiratory rate, heart rate, blood pressure, RA O2 saturation, hospitalization duration.

______________________________________________________ Laboratory findings: leukocyte and lymphocyte count, CRP, D-Dimer, renal and liver function, optional: cytokine levels.

______________________________________________________ Radiologic findings: pulmonary infiltrates, pleural effusion.

Arm Intervention/treatment
Experimental: MesenCure treatment

Clinical interventions:

Health questionnaire, respiratory rate, heart rate, blood pressure, RA O2 saturation, x-ray.

Blood tests: leukocyte and lymphocyte count, CRP, D-Dimer, renal and liver function, optional: cytokine levels.

Biological: MesenCure
Three administrations of MesenCure in addition to standard care

Primary Outcome Measures :

Secondary Outcome Measures :
  1. Improvement in RA-O2 saturation [ Time Frame: 14 days ]
    Elevation to 94% and above

  2. Elevation of lymphocytes level [ Time Frame: 14 days ]
    Elevation compared to day 0

  3. Reduction of CRP [ Time Frame: 14 days ]
    Reduction compared to day 0

  4. Improvement of health questionnaire [ Time Frame: 21 days ]
    Improvement compared to day 0

  5. Reduced hospitalization duration [ Time Frame: 30 days ]
    Reduced compared to clinical site matching historical data

  6. improvement in pulmonary infiltrates/ pulmonary congestion [ Time Frame: 30 days ]
    Improvement compared to day 0

  2. History of drug abuse.
  3. Heavy smokers (above 2 packages a day).
  4. Subjects incapable of giving consent.

Background medical conditions:

  1. Known history of any significant medical disorder, which in the investigator's judgment contraindicates the subject's participation.

  3. Known autoimmune diseases.
  4. Received any investigational drug within 30 days prior to screening day (Visit 1) (Remdesivir is not considered investigational, and is not an exclusion criteria).
  5. Immunocompromised condition from any reason, at screening.
  6. Abnormal clinically significant laboratory test findings, as per the investigator's judgment.
  7. Poorly controlled diabetic subjects (HbA1c > 9%).
  8. Known active lung malignancy.

Concomitant treatment:

  1. Currently treated with Immunosuppressive agents other than corticosteroids used for treating COVID19.
