简要总结

  • This is a phase II randomized study of convalescent plasma for the treatment of non-immune individuals with COVID-19 infection at high risk of complications.
  • Subjects will be considered as having completed the study after 2 months (+/- 5) days, unless consent withdrawal or death occurs first.
  • Subjects will be randomized to receiving convalescent plasma or best supportive care.
  • Patients randomized to best supportive care may receive plasma should they require hospitalization for progression of COVID-19 disease.
  • The final analysis will be conducted once the last subject completes the 2-month visit or withdraws from the study.

详细描述

Overall study design

  • This is a phase II randomized study of convalescent plasma for the treatment of non-immune individuals with COVID-19 infection at high risk of complications.
  • Subjects will be considered as having completed the study after 2 months (+/- 5) days, unless consent withdrawal or death occurs first.
  • Subjects will be randomized to receiving convalescent plasma or best supportive care.
  • Patients randomized to best supportive care may receive plasma should they require hospitalization for progression of COVID-19 disease.
  • The final analysis will be conducted once the last subject completes the 2-month visit or withdraws from the study.

A total of 306 subjects will be recruited, 153 for each arm. If a patient in the best supportive care arm requires hospitalization, the patient will be eligible to receive convalescent plasma if requested and/or deemed medically appropriate by the admitting physician.

Overall study duration

  • The study begins when the first subject (donor or recipient) signs the informed consent. The study will end once the last enrolled subject completes the study (likely a recipient).
  • The expected duration of the study is approximately 12 months.

研究组 & 干预措施

Convalescent Plasma

Experimental

Fresh or frozen plasma will be infused one time to patients

干预措施: Convalescent Plasma (Biological)

Best Supportive Care

Active Comparator

Patients will receive best supportive care. Patients randomized to best supportive care may receive plasma should they require hospitalization for progression of COVID-19 disease.

干预措施: Best Supportive Care (Other)
