Cellular Senescence and COVID-19 Long-Hauler Syndrome

June 10, 2025 updated by: Ryan T. Hurt, M.D., Ph.D., Mayo Clinic

Cellular Senescence and Its Contribution to COVID-19 Long-Hauler Syndrome

The purpose of this study is to test if senescent cells and their secretome contribute to Long-Hauler Syndrome and if a clinical trial of senolytic drugs, which selectively eliminate senescent cells, should be initiated.

Study Population

Longhauler's Cohort: Patients must be at least 18 years or older, have a positive PCR or antibody test within six months, and report any ongoing symptoms associated with Post-COVID or Long-Haulers Syndrome.

Control Cohort: Patients must be at least 18 years or older, have not had a known case of COVID-19 or Longhauler's syndrome.

COVID Control Cohort: Patients must be at least 18 years or older and have had COVID-19 but no known Longhauler's syndrome.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation between features of Long-Hauler Syndrome with markers of cellular senescence and SASP factors
Time Frame: 6 months
If a correlation between features of Long-Hauler Syndrome with markers of cellular senescence and SASP factors can be demonstrated, or SASP factors are higher in Long-Hauler Syndrome clinic patients than age- and sex-matched controls (using archived samples) in this pilot study, a protocol will be submitted to the IRB for a trial in Long-Hauler Syndrome patients of senolytic drugs.
