Study summary

The Primary objective of this study is to determine, using unblinded samples, if it is possible to develop an algorithm for the classification of specific blood RNA from patients with long COVID together and separately from the apparent health normal controls and other medical conditions that share the signs and symptoms of long COVID.

Read the detailed description

Participants will be screened and provide two blood samples28 (+/- 2) days apart. Based on the participants survey results they will be placed into one of fourteen groups that reflect the type of Long COVID the patient is experiencing. Samples will be shipped to the sponsor who will develop an AI process to validate the type of Long COVID and assess its severity. The long term goal is to develop a reliable test to identify the presence of Long COVID and its severity.

Study arms

  • Active comparator
    Participants never infected by SARS-COV-2

    Participants with no history of SARS-COV-2 infection. This is a control arm of the study. Participants will complete an ethnic survey, medical history survey and undergo two blood draws.

    Diagnostic Test: RNA Biomarker Blood Test

  • Active comparator
    Participants with SARS-COV-2 post-infection without long COVID

    Participants with a history of SARS-COV-2 infection, but never developed long term sequalae. This is a control arm of the study. Participants will complete an ethnic survey, medical history survey and undergo two blood draws.

    Diagnostic Test: RNA Biomarker Blood Test

  • Active comparator
    Participants with long COVID and current/active respiratory symptoms

    Participants with a history of SARS-COV-2 infection and developed long term sequalae associated with their respiratory system: continued shortness of breath, etc.. This is an experimental arm of the study. Participants will complete an ethnic survey, medical history survey and undergo two blood draws.

    Diagnostic Test: RNA Biomarker Blood Test

  • Active comparator
    Participants with long COVID and current/active neurological symptoms

    Participants with a history of SARS-COV-2 infection and developed long term sequalae associated with their neurologic system: brain fog, confusion, etc.. This is an experimental arm of the study. Participants will complete an ethnic survey, medical history survey and undergo two blood draws.

    Diagnostic Test: RNA Biomarker Blood Test

  • Active comparator
    Participants who have long COVID with current/active both respiratory and neurological symptoms

    Participants with a history of SARS-COV-2 infection and developed long term sequalae associated with both their respiratory system and their neurologic system. This is an experimental arm of the study. Participants will complete an ethnic survey, medical history survey and undergo two blood draws.

    Diagnostic Test: RNA Biomarker Blood Test

  • Active comparator
    Participants who have other current/active long COVID symptoms

    Participants with a history of SARS-COV-2 infection and developed long term sequalae not associated with respiratory or neurological conditions.

    Diagnostic Test: RNA Biomarker Blood Test

  • Active comparator
    Participants with neurological symptoms prior to 1 November 2019 without SARS-COV-2 infection

    Participants without a history of SARS-COV-2 infection and had neurological conditions prior to 1 November 2019.

What researchers measure

Primary outcomes

  1. Develop algorithm to classify RNA sequences to identify long COVID

    The Primary objective of this study is to determine, using unblinded samples, if it is possible to develop an algorithm for the classification of specific blood RNA from patients with long COVID together and separately from the apparent health normal controls and other medical conditions that share the signs and symptoms of long COVID

    Time frame: 30 days

Secondary outcomes

  1. Develop algorithm to subclassify specific RNA sequences to subclassify types of Long COVID

    The secondary objective of this study is to determine if it is possible to develop an algorithm that can subclassify specific blood RNA biomarkers in long COVID patients into various symptom-related subcategories to provide clinically relevant treatment options.

    Time frame: 30 Days
