About this study

Official title: Probing Metabolism, Circulating Inflammatory Molecules, Extracellular Vesicles and Immune Dysregulation in Individual Immune Cells in ME/CFS

This study aims to collect and identify key outcome measures or disease parameters in ME/CFS that are altered during elevated symptoms relative to baseline by gathering information before and after symptom provocation using a two-day cardiopulmonary exercise test.

Read the detailed description

The phenomenon of post-exertional malaise (PEM), in which an ME/CFS patient's symptoms are elevated following even low-level exertion, is a hallmark feature of the disease. The cause of PEM, like the cause of ME/CFS, is not understood. This study aims to utilize a two-day CPET to invoke PEM. This provides a unique opportunity to collect data on how key outcome measures or disease parameters are altered during elevated symptoms relative to baseline within each patient by gathering information before and after symptom provocation.

A total of 90 participants and 90 controls will undergo CPET testing. Participation will be split amongst three different sites (Ithaca, NY, New York, NY, and Los Angeles, CA). Subjects will be located in urban and rural areas to establish relatively diverse study populations.

This study is a component of the Cornell ME/CFS Collaborative Research Center (CRC). Blood samples taken before and after CPET will be utilized in associated projects with the Cornell ME/CFS CRC. CPET data along with the analysis of blood samples has great potential to reveal why exercise negatively affects ME/CFS patients and thus perhaps why patients are also impaired even before increasing their activity level.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Two-day cardiopulmonary exercise testOther

    A series of two cardiopulmonary exercise tests (CPETs) performed over two days. Participants will perform a CPET and then will return approximately 24 hours later to perform the second CPET. The CPET begins with 3 minutes of seated rest followed by cycling during incremental workloads which increases 15 watts throughout each minute of exercise. The participant will cycle until volitional exhaustion and/or the participant and/or test administrator determines to stop the test. Actual exercise time usually varies between 8-10 minutes.

What is being measured

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

  1. Volume of oxygen consumed at peak effort

    Volume of oxygen consumed at peak effort during CPET 1 and during CPET 2.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  2. Volume of oxygen consumed at ventilatory/anaerobic threshold (VAT)

    VAT is a non-invasive surrogate measure for anaerobic threshold, which is indicated during incremental exercise by a non-linear increase in rate of carbon dioxide production relative to rate of oxygen consumption.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  3. Rate of work performed at peak effort

    Rate of work performed at peak effort during CPET 1 and during CPET 2. Rate of work is measured in Watts.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  4. Rate of work performed at VAT

    Rate of work performed at VAT during CPET 1 and during CPET 2. Rate of work is measured in Watts.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  5. Heart rate at peak effort

    Heart rate at peak effort during CPET 1 and during CPET 2.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  6. Heart rate at VAT

    Heart rate at VAT during CPET 1 and during CPET 2.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  7. Systolic blood pressure at seated rest

    Systolic blood pressure at seated rest 1-minute before the start of CPET 1 and 1-minute before the start of CPET 2.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  8. Systolic blood pressure at peak effort

    Systolic blood pressure at peak effort during CPET 1 and during CPET 2.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

  9. Respiratory Exchange Ratio (RER) at peak effort

    RER at peak effort during CPET 1 and during CPET 2. RER is calculated as the rate of carbon dioxide production divided by the rate of oxygen consumption, and during exercise is an indicator of participant effort.

    Measured: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.

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 21 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 7 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

Volume of oxygen consumed at peak effort (time frame: During intervention on day 1 and during intervention on day 2; assessed through study completion, approximately 4 years from study start date.). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04026425, which also lists 1 linked publication.

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.
