Brief Summary:
This is an open label pilot study designed to provide access to treatment with investigational convalescent plasma and assess the relationship between NAb titers in the investigational convalescent plasma compared to changes in NAb levels in the recipient in hospitalized patients with COVID-19.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Convalescent Plasma Phase 2

Detailed Description:

Primary objectives are as follows:

  1. To provide access to treatment with investigational convalescent plasma to inpatients with documented COIVD-19 infection
  2. To measure NAb titers in an aliquot of the CP administered, to measure the volume of CP administered, and determine whether there is a correlation between the NAb dose (in NAb units/kg body weight, where a unit is the reciprocal of the endpoint NAb titer in the CP multiplied by the volume in ml) and change or lack of change when comparing pre-treatment and day one NAb titers.

Secondary, exploratory objectives are as follows:

  1. To evaluate the safety of convalescent plasma (CP) administration in hospitalized COVID-19 patients
  2. To evaluate viral shedding of SARSCoV-2 in nasopharyngeal or nasal samples before and on days 3, 7, and 14 after CP transfusion
  3. To perform genomic analysis of the SARS-CoV-2 from patients before and after treatment with CP transfusion
  4. Determine cumulative incidence of disease severity (transfer to ICU, type of respiratory support, LOS, and mortality)

Estimated Enrollment : 30 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: Open, Non-comparative Pilot Study to Provide Access to Treatment With Investigational Convalescent Plasma and Measure Antibody Levels in Patients Hospitalized With COVID-19
Actual Study Start Date : April 28, 2020
Estimated Primary Completion Date : April 28, 2021
Estimated Study Completion Date : April 28, 2025

Arm Intervention/treatment
Experimental: Single Arm
The investigational product is anti-SARS-CoV-2 convalescent plasma obtained from former patients identified as having recovered from COVID-19 and obtained by Vitalant from local and national donors following national blood donation guidelines. All subjects receive the convalescent plasma.
Drug: Convalescent Plasma
Study subjects will receive 1 unit (200mL) of SARS-CoV-2 convalescent plasma collected from a single donor who recovered from COVID-19.




Primary Outcome Measures :
  1. Correlation between the NAb dose titer in the convalescent plasma and change or lack of change when comparing pre-treatment and day one NAb titers to inpatients with documented COIVD-19 infection [ Time Frame: 14 days ]
    To provide access to treatment with investigational convalescent plasma and measure NAb titers in an aliquot of the CP administered, to measure the volume of CP administered, and determine whether there is a correlation between the NAb dose titer in the CP and change or lack of change when comparing pre-treatment and day one NAb titers to inpatients with documented COIVD-19 infection


Secondary Outcome Measures :
  1. Rapid deterioration as evidenced by increase in ordinal or news score within 4 hours of transfusion [ Time Frame: 14 days ]
    To evaluate the safety of convalescent plasma (CP) administration as determined by rapid deterioration of respiratory or clinical status on transfusion of SARS-CoV-2 convalescent plasma

  2. Number of participants with clearance of viral shedding of SARSCoV-2 in nasopharyngeal or nasal samples [ Time Frame: 14 days ]
    To evaluate number of participants with clearance of viral shedding of SARSCoV-2 in nasopharyngeal or nasal samples on days 3, 7, and 14 after CP transfusion.
