Outcome Measures

Primary Outcomes (1)

  • Mechanical Ventilation or Death Endpoint

    Number of participants that progressed to mechanical ventilation or death within the first 14 days of enrollment.

    Day 14

Secondary Outcomes (2)

  • Mechanical Ventilation or Death Endpoint

    Day 28

  • 8-Point Ordinal Scale Endpoint

    Day 29

Study Arms (2)

COVID-19 Convalescent Plasma

EXPERIMENTAL

Subjects in the COVID-19 convalescent plasma group will receive a single infusion of 250 ml anti-SARS-CoV-2 convalescent fresh frozen plasma, ABO compatible with the patient, within 24 hours of randomization.

Biological: COVID-19 Convalescent Plasma (CCP)

Placebo

PLACEBO COMPARATOR

Subjects in the placebo group will receive a single infusion of 250 ml of standard fresh frozen plasma, ABO compatible with the patient, within 24 hours of randomization.

Biological: Placebo

Interventions

COVID-19 Convalescent Plasma (CCP) is a form of passive antibody therapy that involves the administration of anti-SARS-CoV-2 antibodies to a susceptible individual for the purpose of preventing or treating the infectious disease it causes. Convalescent plasma for this trial will be obtained from Vitalant (or American Red Cross if necessary). Patients identified as having recovered from COVID-19 will serve as potential donors. Potential donors will be screened using an anti-SARS-CoV-2 serologic assay and antibody levels will be determined.

COVID-19 Convalescent Plasma
PlaceboBIOLOGICAL

Standard plasma will be obtained from Vitalant (or American Red Cross if necessary) and will be either collected prior to 12/1/2019 or tested and confirmed to be negative for anti-SARS-CoV-2.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients ≥18 years of age
  • Hospitalized with COVID-19
  • Enrolled within 72 hours of hospitalization OR within day 14 from first signs of illness
  • Pulmonary infiltrates on chest imaging
  • Oxygenation of \<95% on room air
  • Laboratory confirmed COVID-19

You may not qualify if:

  • Contraindication to transfusion due to inability to tolerate additional fluid, such as due to decompensated congestive heart failure
  • Baseline requirement for oxygen supplementation prior to COVID-19 infection or use of positive pressure therapy for sleep disordered breathing
  • Currently experiencing severe hypoxemic failure, as defined in study endpoints
  • Prior receipt of plasma products, IVIG, or hyperimmune globulin within past 3 months
  • Not currently enrolled another interventional clinical trial of COVID-19 treatment.
  • Note: If taking medications with potential anti-COVID activity for the purpose of COVID-19 treatment that do not yet have data to support efficacy, such as IL-6 antagonists, these medications must be stopped prior to enrollment. Receipt of current standard of care COVID-19 treatment, including remdesivir and dexamethasone is permitted and should be recorded as a concomitant medication.

Limitations and Caveats

This study was limited by the small sample of hospitalized, hypoxic patients, limiting the generalizability of the results. Most participants were beyond 72 hours of symptom onset, the period when studies suggest CCP is most likely to be beneficial.

Masking Details
Study investigators analyzing the data and participants will be blinded to the randomization. It may not be feasible to blind nursing staff to the treatment assignment to ensure proper ABO checking of the plasma unit at bedside per standard transfusion procedures, but every effort will be made to preserve blinding of the investigators, participant, and primary team providing care. An unblinded research assistant who is not involved in other aspects of the study will randomize the participant once enrolled. Randomization will be provided to an unblinded provider who is not part of the care team who will place the order for the plasma (CCP vs. control plasma) using a paper order that will not be part of the electronic medical record. The safety monitoring committee (SMC) will review study data, including unblinded data, to evaluate the safety, efficacy, study progress, and conduct of the study.
