简要总结

This is a randomized phase II placebo controlled clinical trial. Active arm: Allogeneic Wharton's jelly derived MSCs (WJ-MSCs). Both groups will receive standard of care treatment for COVID (e.g. dexamethasone)

详细描述

Allogeneic Wharton's jelly-MSCs (WJ-MSC) will be provided by NextCell Pharma under the commercial name of ProTrans®. ProTrans® will be administered at a fixed dose of 100 million cells per patient in a single infusion at bedside.

Placebo: Sodium chloride buffer supplemented with 5% HSA and 10% DMSO same volume and mode of administration as treatment group (NextCell Pharma).

入选标准

  • Male or female, aged 18 years-old or older
  • Laboratory-confirmed SARS-CoV-2 infection determined by reverse-transcription polymerase chain reaction (RT-PCR) prior to randomization
  • Hospitalized patients
  • Severe COVID-19 pneumonia defined as patients who cannot saturate > 96% on 4 L/min but are NOT on "non-invasive" ventilation nor invasive mechanical ventilation nor Extracorporeal membrane oxygenation (ECMO). Patients on high flow would be eligible if they receive treatment in a non-critical care unit only.
  • Use of contraception or acceptable birth control for the duration of the study in women of childbearing potential
  • Provision of written or verbal informed consent by the patient or designated substitute decision maker

排除标准

  • Inability to provide informed consent
  • Patients expected to survive less than 24 hours
  • Advanced directives of patient's wishes to refuse intubation.
  • Patients on mechanical ventilation
  • Pregnant women [pregnancy defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotrophin (hCG) laboratory test]
  • Breastfeeding
  • Weight > 100 kg or < 50 kg
  • Cancer not in remission or active serious illness unrelated to COVID-
  • Any of the following laboratory results at screening: Absolute neutrophil count (ANC) ≤ 1.0 x 109/L, Platelets (PLT) < 50 G /L, Alanine transaminase (ALT) or Aspartate transaminase (AST) > 5N, eGFR < 30 mL/min
  • Current documented bacterial infection
  • Known infection with Human immunodeficiency virus, Treponema pallidum, Hepatitis B antigen (serology consistent with previous vaccination and a history of vaccination is acceptable) or Hepatitis C
  • On-going therapy against tuberculosis, or exposed to tuberculosis or have travelled in areas with high risk of tuberculosis or mycosis within the last 3 months
  • Known allergies to a component of the ProTrans® product
  • Pre-existing chronic respiratory diseases requiring long-term oxygen therapy or severe pulmonary hypertension (PAPS >30 mm HG) or pulmonary fibrosis
  • Pre-existing cirrhosis with basal Child and Pugh of C
