Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have had a previous suspected, probable, or confirmed SARS-CoV-2 infection.

Probably not a fit

Patients who do not have a history of SARS-CoV-2 infection or those under 18 years of age may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This platform protocol is designed to evaluate various interventions aimed at improving exercise intolerance and post-exertional malaise (PEM) in patients suffering from Long COVID. It is a multi-center, randomized, controlled trial that allows for flexibility in interventions, which may include personalized cardiopulmonary rehabilitation, structured pacing, education, and usual care. Participants will be screened for eligibility and then randomized to either an intervention group or a control group based on specific criteria. The goal is to enhance exercise capacity, daily activity tolerance, and overall quality of life for individuals affected by Post-Acute Sequelae of SARS-CoV-2 Infection (PASC).

Why it matters

Potential benefit: If successful, this study could significantly improve the quality of life and daily functioning for patients suffering from Long COVID.

How similar studies have gone: Other studies have shown promise in addressing similar issues related to Long COVID, but this platform approach is relatively novel.

Inclusion Criteria:

1. ≥ 18 years of age at the time of enrollment
2. Previous suspected, probable, or confirmed SARS-CoV-2 infection, as defined by the Pan American Health Organization\*

   * Suspected\* or probable SARS-CoV-2 infection will only be allowed if it occurred before May 1, 2021, and will be limited to no more than 10% of the study population. Otherwise, confirmed cases are required.

   Suspected case of SARS-CoV-2 infection - Three options, A through C:

   A. A person who meets the clinical OR epidemiological criteria. Clinical criteria: Acute onset of fever AND cough (influenza-like illness) OR Acute onset of ANY THREE OR MORE of the following signs or symptoms: fever, cough, general, weakness/fatigue, headache, myalgia, sore throat, coryza, dyspnea, nausea, diarrhea, anorexia. Epidemiological criteria: Contact of a probable or confirmed case or linked to a COVID-19 cluster; or B. Acute respiratory infection with history of fever or measured fever of ≥ 38°C; and cough; with onset within the last 10 days; and who requires hospitalization; or C. With no clinical signs or symptoms, NOR meeting epidemiologic criteria with a positive professional use or self-test SARS-CoV-2 Antigen-Rapid Diagnostic Test.

   Probable case of SARS-CoV-2 infection:

   A. A patient who meets clinical criteria above AND is a contact of a probable or confirmed case or is linked to a COVID-19 cluster.

   Confirmed case of SARS-CoV-2 infection - Two options, A and B:

   A. A person with a positive nucleic acid amplification test, regardless of clinical criteria OR epidemiological criteria; or B. Meeting clinical criteria AND/OR epidemiological criteria (See suspected case A above for criteria). With a positive professional use or self-test SARS- CoV-2 Antigen-Rapid Diagnostic Test.
3. Self-reported limitation to physical activity due to the presence of symptoms such as fatigue, shortness of breath, and/or PEM following a SARS-CoV-2 infection, that has persisted for at least 12 weeks and is present at the time of consent.
4. Willing, able, and agree to provide informed consent, complete questionnaires and outcome assessments, and participate in the study, including assigned intervention or control and study visits whether remote, hybrid, or in-person.

Exclusion Criteria:

An individual who meets any of the following criteria will be excluded from participation in this study:

1. Known active acute SARS-CoV-2 infection ≤ 4 weeks prior to the consent.
2. Known prior diagnosis of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), not related to SARS-CoV-2 infection.
3. Current or recent use (within the last 14 days) of a formal program utilizing one or more of the current study intervention(s) or similar intervention(s) to treat the underlying condition, unless a washout period is permitted per Appendices.
4. Participation in another interventional clinical trial.
5. Any condition that would make the participant, in the opinion of the investigator, unsuitable for the study.
