Clinical Trial Summary

The purpose of this research study is to find out if CCP is safe and to determine the safest and most effective level of anti-viral antibody when given to people admitted to the hospital with confirmed COVID-19 infection. Participants enrolled on this study will be transfused with 2 units of CCP through an IV. These units will be given one at a time 4 to 24 hours apart. Participants will be randomized to receive either 2 units with standard antibody levels as recommended by the FDA or 2 units with an antibody level higher than that recommended by the FDA. This study is experimental and CCP is investigational and has not been approved by the FDA for the treatment of COVID-19. The CCP is collected per FDA guidelines from persons recovered from COVID-19 infection. The plasma contains antibodies and possibly other properties that inhibit the virus. The investigators do not know if the level of antibodies present in the CCP will make a difference in how the participant's body is able to fight the infection and hope to learn that in this study.

Description:

This randomized, double-blinded, phase 2 trial will assess the efficacy and safety of anti-SARS-CoV-2 convalescent plasma in hospitalized patients with less than 8 days of symptoms. Eligible participants will receive institutional-guided standard-of-care (SOC) and ABO-compatible convalescent COVID-19 plasma (CCP). The CCP units will be tested for the presence of anti-SARS-CoV-2 antibodies and pre-assigned as high-titer (CCP1) or standard-titer (CCP2) in a 1:1 randomization. Participants and clinical investigators will be blinded to the CCP titer group identities.

The investigators plan to enroll approximately 56 participants (28 in each group) at UNC-Chapel Hill. Participants will be randomized within 48 hours of admission to a COVID service and will receive convalescent plasma within 24 hours of randomization. At least two units of CCP will be transfused 4-24 hours apart on study Day 0. If available, a third unit may be administered. All participants will undergo a series of safety and efficacy assessments pre-, during, and post-transfusion. Samples for research will be collected on Day 0 through Day 28, unless previously discharged. Additionally, after discharge, participants can provide longitudinal samples collected at 1, 3, and 6-month timepoints after the infusion.

Primary	Total Number of Serious Adverse Events (SAE) Through Study Day 14	Total number of SAE among all participants through Day 14; Definition of SAE per protocol and will only be included if related to COVID-19 Convalescent Plasma (CCP): 1. Death; 2. Life-threatening (immediate risk of death); 3. Prolongation of existing hospitalization; 4. Persistent or significant disability or incapacity; OR 5. Important medical events that may not result in death, be life threatening, or require intervention or escalation of care may be considered a serious adverse event when, based upon appropriate medical judgment, they may jeopardize the subject and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Examples of such medical events include allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood dyscrasias, or convulsions that do not result in inpatient hospitalization.	14 days
