Brief Summary:
The objectives of this intermediate-size expanded access protocol are to assess the safety and efficacy of remestemcel-L in participants with MIS-C associated with COVID-19.

Condition or disease Intervention/treatment
Multisystem Inflammatory Syndrome in Children (MIS-C) Associated With Coronavirus Disease (COVID-19) Biological: Remestemcel-L Drug: Hydrocortisone Drug: Diphenhydramine

Detailed Description:
This intermediate-size expanded access protocol plans to treat approximately 50 children or adolescents, male and female, with MIS-C associated with COVID-19. Participants who are 2 months to 17 years of age, inclusive, will be enrolled at multiple clinical sites across the United States.

Layout table for eligibility information
Ages Eligible for Study:   2 Months to 17 Years   (Child)
Sexes Eligible for Study:   All

Inclusion Criteria

  1. 2 months to 17 years of age, inclusive
  2. Positive for current or recent SARS-CoV-2 (COVID-19) infection by real-time reverse transcription polymerase chain reaction (RT-PCR), serology, or antigen test; or COVID-19 exposure within the 4 weeks prior to the onset of symptoms AND no alternative plausible diagnoses
  3. Presenting with:

    • Fever (>38.0°C or >100.4°F for ≥24 hours) or reporting subjective fever lasting ≥24 hours
    • Laboratory evidence of inflammation with high sensitivity C-reactive protein (hsCRP) ≥4.0 milligrams per deciliter (mg/dL) and associated abnormalities of at least one of the following:

      • elevated erythrocyte sedimentation rate (ESR)
      • elevated fibrinogen
      • elevated procalcitonin
      • elevated d-dimer
      • elevated ferritin
      • elevated lactic dehydrogenase (LDH)
      • elevated interleukin 6 (IL-6)
      • elevated neutrophils
      • reduced lymphocytes
      • low albumin
    • Clinically severe multisystem illness requiring hospitalization with evidence for cardiac involvement plus at least one other organ involvement (renal, respiratory, hematologic, gastrointestinal, dermatologic or neurological)

      • Cardiac involvement is defined as reduced left ventricular ejection fraction (<55%) in addition to at least one of the following:

        • increased troponin I,
        • increased N-terminal pro-B-type natriuretic peptide (NT-proBNP) or BNP and/or
        • echocardiographic and/or other imaging evidence of left anterior descending coronary artery (LAD) and/or right coronary artery (RCA) dilation associated with a z-score > 2.5
  4. If on mechanical ventilation or ECMO, ≤72 hours post initiation of the respiratory support device

Exclusion Criteria

  1. Documented other microbial cause for MIS-C including bacterial sepsis, staphylococcal or streptococcal shock syndromes, or infections associated with myocarditis such as enterovirus. Of importance, waiting for results of these investigations should not delay initiation of remestemcel-L therapy.
  2. Females who are pregnant or lactating
  3. Body mass index (BMI) ≥40 kilograms per square meter (kg/m^2)
  4. Known hypersensitivity to dimethyl sulfoxide (DMSO) or to porcine or bovine proteins
  5. Aspartate aminotransferase/alanine transaminase (AST/ALT) ≥5x upper limit of normal (ULN)
  6. Creatinine clearance <30 mL/min
  7. Serum creatinine >2 mg/dL
  8. Any end-stage organ disease which in the opinion of the treating physician may possibly affect the safety of the remestemcel-L treatment.
