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.
Day 1 Week 1 (Baseline), Week 5, Week 9, Week 13
Erythrocyte sedimentation rate (ESR)
Clinical biomarker parameter (ESR) is a blood test that detects and monitors inflammation in the body.
Day 1 Week 1 (Baseline), Week 5, Week 9, Week 13
C-reactive protein (CRP)
A measure of Clinical biomarker parameter (CRP), is an inflammatory marker.
Day 1 Week 1 (Baseline), Week 5, Week 9, Week 13
6-minute walk test (6MWT)
The 6MWT is simply a record of the distance (in meters) traveled by a given patient at his or her self-selected walking speed over a period of six minutes.
Day 1 Week 1 (Baseline), Week 5, Week 9, Week 13
Short physical performance battery (SPPB)
Clinical biomarker parameter (SPPB) assesses lower extremity function in older adults. The test battery consists of three physical tasks (walking, sit-to-stand and balance) to assess functional mobility. The test will be performed according to standardized procedure. The maximal total score is 12 and higher total scores indicate a better lower extremity functioning.
