A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Adults ≥ 18 years of age and ≤ 65 years of age
- Previous Covid-19 (SARS-CoV-2 infection) within the past four years, as determined by the site investigator using the following certainty scale (based on available clinical history and/or serologic data): 3 – Confirmed Infection (PCR or n-Capsid Test): Prior positive nasopharyngeal or salivary PCR test for Covid-19 (documented proof and/or verbal confirmation by participant) or has positive nucleocapsid antibodies results. 2 – Probable Infection (Antigen Test): Participant verbally confirms a prior positive rapid antigen test without PCR confirmation. 1 – Possible Infection (Viral Syndrome and Epidemiological Link): Participant verbally confirms experiencing symptoms consistent with Covid-19 infection and has an epidemiological link (i.e., exposure to a confirmed case) without any positive testing.
- Persistent or new symptoms diagnosed as "Long Covid" as defined by the World Health Organization; "the continuation or development of new symptoms 3 months after the initial SARS-CoV-2 infection (Covid-19), with these symptoms lasting for at least 2 months with no other explanation". This diagnosis may come from a healthcare professional experienced in Long Covid diagnosis, or the site investigator. These symptoms must be present for more days than not and must not have been present prior to the onset of SARS-CoV-2 (Covid-19) infection.
- At the time of screening, participants should be experiencing at least one of the following self-reported symptoms or symptom clusters. Participant has self-reported issues with: Fatigue Breathing Circulation Memory, thinking, and/or communication Muscles and/or joints These five symptoms or symptom clusters were selected based on unpublished data from the National Institutes for Health and Care Research (NIHR, United Kingdom) and their alignment with five validated SBQ scales. The selection was driven by their prevalence and their significant impact on quality of life as reported in symptom assessments.
- Participant has the ability and is willing to follow study procedures throughout the study
- Participant can provide informed consent
You likely can't join if
- Participants who do not meet the criteria outlined above
- Absolute lymphocyte count (ALC) below 500 cells/mm³
- Alkaline phosphatase (ALP) levels equal to or greater than three times the upper limit of normal (ULN)
- Creatine phosphokinase (CPK) levels equal to or greater than three times the ULN
- Platelet count below 100,000 cells/mm³, confirmed with repeat testing
- Platelet count above 500,000 cells/mm³, confirmed with repeat testing
