Brief Summary

Over the past decades, healthcare systems face significant challenges to meet the needs of an aging population due to progressive debility, functional decline and chronic diseases development. While there is a growing appreciation of the potential impact of mTOR inhibitors on slowing aging processes, preventing chronic disease and prolonging healthy lifespan, a major challenge in developing clinical trials to establish the clinical efficacy of mTOR inhibitors is the absence of pharmacokinetics (PK) and pharmacodynamics (PD) data in older adults. The proposed study will provide the foundation for future clinical trials assessing the role of mTOR inhibitors on aging related indications

  • Senescence-associated secretory phenotype (SASP) index

    Clinical biomarker parameter (SASP) index is a clinical biomarker parameter that measures the level of proteins secreted by senescent cells in the body.
