Trial summary

Convalescent Plasma for COVID-19 Research (CONCOR-Donor) study, is a national, natural history study of plasma donors recovered from COVID-19. CONCOR-Donor study will address immune response, duration of protective immunity, and clinical factors and host genetics contributing to the variability of immune response.

About this study

Official title: Convalescent Plasma for COVID-19 Research (CONCOR) Donor Study

Convalescent Plasma for COVID-19 Research (CONCOR-Donor) study, is a national, natural history study of plasma donors recovered from COVID-19. CONCOR-Donor study will address immune response, duration of protective immunity, and clinical factors and host genetics contributing to the variability of immune response. We will also study long-term outcomes from COVID-19 infection. Results from the study will help define therapeutic strategies for COVID-19.

Read the detailed description

The outbreak caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) led to the global pandemic. There are currently no proven treatments for coronavirus disease (COVID-19), however, convalescent plasma has emerged as a potential therapeutic to prevent clinical deterioration. Convalescent plasma was successfully used for other infections, in small numbers, but there is limited evidence for the efficacy of administering specific, neutralizing antibodies by transfusion of convalescent plasma. The unknown role for convalescent plasma in treating COVID-19 necessitates further study.

As trials are underway to determine efficacy of using convalescent plasma, we will use this unique opportunity to conduct a national longitudinal cohort study of 1000 persons recovered from COVID-19 and volunteer to donate convalescent plasma. Our aims are to:1) determine if the variability of titers of viral neutralizing antibody and ELISA antibody are associated with clinical and demographic factors; 2) determine duration of protective immunity in recovered persons over 1 year and if modified by clinical and demographic factors; 3) determine genetic risk predictors of the antibody response, and 4) create a biorepository available to researchers from across Canada. Based on the World Health Organization (WHO) Coordinated Global Research Map, this project addresses the priority of the natural history of COVID-19 and clinical characterization of antibody response in the convalescent phase and beyond.

Study groupRoleWhat they receive
COVID-19 ConvalescentsThe cohort will include up to 1000 persons recovered from COVID-19, ages 17 - 65, that will provide a written consent form to participate in the study, complete questionnaires and provide a blood sample.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Seroprevalence and duration of protective immunity

    Determine if the titers of SARS-CoV-2-specific neutralizing antibody and serum ELISA antibodies, are correlated with clinical and demographic factors such as age, sex, comorbidities, geographic region, and severity of prior COVID-19 symptoms, during the convalescent phase.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19, run by The Hospital for Sick Children at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 25 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Seroprevalence and duration of protective immunity (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Oct 2022.
