Purpose

The purpose of this study assess the efficacy and safety of anti-SARS-CoV-2 convalescent plasma in hospitalized patients with acute respiratory symptoms up to 14 days after the onset of initial symptoms.

Inclusion Criteria

for Enrollment: 1. Patients ≥18 years of age 2. Hospitalized with COVID-19 3. Enrolled within 72 hours of hospitalization OR within day 14 from first signs of illness 4. Pulmonary infiltrates on chest imaging 5. Oxygenation of <95% on room air 6. Laboratory confirmed COVID-19

Exclusion Criteria

  1. Contraindication to transfusion due to inability to tolerate additional fluid, such as due to decompensated congestive heart failure 2. Baseline requirement for oxygen supplementation prior to COVID-19 infection or use of positive pressure therapy for sleep disordered breathing 3. Currently experiencing severe hypoxemic failure, as defined in study endpoints 4. Prior receipt of plasma products, IVIG, or hyperimmune globulin within past 3 months 5. 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. Note: Pregnancy is not exclusionary but will merit additional discussion of risks & benefits in the context of ongoing pregnancy

Intervention Model
Parallel Assignment
Intervention Model Description
Subjects enrolled in the study will be randomized using a web based randomization procedure to receive convalescent plasma versus non-immune plasma at a 1:1 ratio.
Primary Purpose
Treatment
Masking
Triple (Participant, Care Provider, Investigator)
Masking Description
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.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
COVID-19 Convalescent Plasma
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)
    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.
Placebo Comparator
Placebo
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
    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.

Detailed Description

A total of 50 eligible subjects will be randomized in a 1:1 ratio to receive either convalescent fresh frozen plasma (frozen within 8 hours of collection) of PF24 (frozen within 24 hours) from blood donors who have recovered from COVID-19 containing antibodies to SARS-CoV-2 or control (standard fresh frozen plasma collected prior to 12/1/2019 or with documented negative SARS-CoV-2 antibody). Should additional anti-COVID agents (anti-viral and/or anti-inflammatory) become available for use as standard of care during implementation, the sample size will be recalculated and increased to account for the estimated impact that these agents may have on the reducing the progression to the primary endpoint of severe hypoxemia.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
