About this study

To collect blood and urine samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and SEID (Systemic Exertion Intolerance Syndrome) and controls for genomic, viral and metabolomic testing.

Read the detailed description

To analyze gene expression (genomic) and viral analysis data from patients diagnosed with ME/CFS, the study will collect blood samples (finger stick) and information from up to 500 subjects for analysis. In addition, urine will be collected for all subjects to evaluate the study subject's metabolomics.

All participants will complete a single Study Collection event consisting of at least one MCD (2nd sample is optional) and one urine collection from home: 10% of each group (ME/CFS and Control) will complete a second Study Collection event approximately 1 to 2 weeks after the initial Study Collection. The second collection is to compare data between two collections from the same participants to observe any time-related changes in the results.

What is being measured

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

  1. Collect blood samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and Systemic Exertion Intolerance Syndrome (SEID), and controls for genomic testing.

    To enable research focused on discriminating differentiated symptoms of various sources of CFS from other autoimmune and viral pathogenesis of disease which could prove valuable in researching for inflammation and immunity related therapeutics.

    Measured: 3 months

  2. Collect blood samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and Systemic Exertion Intolerance Syndrome (SEID), and controls for viral testing.

    To enable research focused on discriminating differentiated symptoms of various sources of CFS from other autoimmune and viral pathogenesis of disease which could prove valuable in researching for inflammation and immunity related therapeutics.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Fatigue Syndrome, run by DxTerity Diagnostics 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 17 inclusion and 9 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 15 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?

Collect blood samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and Systemic Exertion Intolerance Syndrome (SEID), and controls for genomic testing. (time frame: 3 months). The study lists 3 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 15 Feb 2022.
