Treatment With Investigational Convalescent Plasma and Measure Antibody Levels in Patients Hospitalized With COVID-19

University of New Mexico12 enrolled

Overview

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.

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)

Medical Language ↔ Plain English

Inclusion Criteria: 1. Patients must be 18 years of age or older. 2. Hospitalized with COVID-19 respiratory symptoms and confirmation via COVID-19 SARS-CoV-2 RT-PCR testing. If COVID-19 test results are pending or done at enrolment, test results must be positive prior to administration of convalescent plasma. 3. Patient (or legally authorized representative, LAR) is willing and able to provide written informed consent and comply with all protocol requirements. 4. For patients unable to consent, consent by the legally authorized representative (LAR) may be obtained by phone. Exclusion Criteria: 1. Female subjects with positive pregnancy test or breastfeeding. 2. Receipt of pooled immunoglobulin in past 30 days. 3. Contraindication to transfusion or history of prior severe allergic reactions to transfused blood products. 4. On ECMO or in refractory shock at entry
