About this study

ImmuneRACE is a study, which is designed to better understand the immune response to COVID-19. This is critically important because the immune system may be able to tell us important information about how our own bodies detect and respond to the disease that current tests cannot. De-identified data collected from this study may accelerate the development of better diagnostics for COVID-19 and improve outcomes for many.

PURPOSE Aim 1. Compare disease-specific TCR signatures in patients vs. controls Aim 2. Identify antigens that elicit a T-cell response Aim 3. Risk Stratification based on immune signature Aim 4. Early detection

Secondary Aim:

Aim 5. Identify and/or confirm antigenic binding (BCR PairSEQ/neutralizing antibodies)

STUDY POPULATION Approximately 1000 individuals, between the ages of 18 - 89 Cohort 1. EXPOSED to someone with a confirmed diagnosis of COVID-19 Cohort 2. ACTIVE COVID-19

Individuals with a previously confirmed diagnosed and cleared from active infection by either:

Testing negative on two consecutive swab tests, or Cleared by a healthcare professional, or Resolution of symptoms

METHODS Decentralized study (visits occur at participant's houses) Utilizing remote phlebotomy to collect (1) whole blood, (2) serum, (3) nose or throat swab Collection of relevant metadata by electronic questionnaire

What is being measured

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

  1. Comparison of disease-specific TCR signatures in patients and controls

    We will run immunoSEQ on approximately 1000 patient samples with disease status unblinded. After sequencing these samples, we will quantitatively describe the compartment of the T-cell repertoire specific for the disease of interest. We will then use these data to construct a classifier that accurately distinguishes patients from controls.

    Measured: Baseline

  2. Identify the immunodominant antigens that elicit a T-cell response to COVID-19

    We developed technology to query the antigen specificity of the T-cell repertoire to hundreds of peptide epitopes in a single blood sample5. This technology not only allows us to parse out immunodominant epitopes of a given infection from irrelevant epitopes, but also allows us to determine the TCR sequences of the T cells responding to these immunodominant epitopes. We will use this technology to determine which peptide epitopes derived from the SARS-CoV-2 genome commonly elicit an immunodominant T-cell response in different samples. The TCR sequence data generated from these studies will be used to boost the diagnostic classifier obtained in Aim 1. In addition, the identification of immunodominant epitopes can be disseminated to fuel studies in vaccine design and antigen specific T-cell responses relating to clinical outcome in other labs.

    Measured: Baseline

  3. Risk Stratification based on an individual's immune signature

    There is a critical need for a reliable risk stratification test to enable treatment prioritization given the potentially massive number of symptomatic patients. Despite an emerging understanding of the diagnosis of COVID-19, how it spreads, and the death rate, there is no currently available way to predict who needs hospitalization beyond age associated risk and limited epidemiologically linked comorbidities.

    Measured: Baseline

  4. Determine whether an immune signature can be detected in individuals exposed to SARS-CoV-2 earlier than currently available tests

    Another critical need to contain the spread of SARS-CoV-2 is to determine the false negative rate of the RNA test in asymptomatic people and offer an alternative diagnostic that is more sensitive in this cohort. For example, it is possible that early stage disease is not picked up by RNA tests because the virus may be isolated to regions such as the lower respiratory cavity that are not assessed by standard testing methods. We aim to determine whether the immune response can be used to detect the virus from a simple blood test thereby providing a more sensitive test in asymptomatic people even if the virus itself is not directly detectable in the upper respiratory region.

    Measured: Baseline

Secondary outcomes (1)
  1. Explore whether additional research assays could potential identify and/or confirm antigenic binding

    As a secondary aim, Adaptive will perform explorational research with additional sequencing-based research assays to profile the adaptive immune system, such as, but not limited to TCR pairSEQ26 and B-cell receptor (BCR) pairSEQ3. These assays use a combinatorial method for pairing TCR alpha and beta chain sequences and BCR heavy and light chain sequences. The output is a large set of full length paired BCR or TCR sequences, which allows reconstruction of a functional antibody or TCR. We regularly utilize the results of our pairSEQ assays to identify and/or confirm antigenic binding. For the case of BCR pairSEQ, the resulting antibody sequences could potentially have therapeutic value for imparting passive immunity.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19, run by Adaptive Biotechnologies at 1 site in United States.

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 2 inclusion and 14 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: finished, as of the sponsor's last update on 16 Feb 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 United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Comparison of disease-specific TCR signatures in patients and controls (time frame: Baseline). The study lists 4 primary outcomes in all. 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 16 Feb 2022.
