Rapamycin and Everolimus to support healthier aging in older adults

RESTOR [Rapamycin and Everolimus Study Towards Older Rejuvenation]: An exploratory PK/PD study of mTOR inhibition in older human subjects

NIH-funded research University of Texas Hlth Science Center · NIH-11163366

Healthy adults aged 65–90 will take short courses of rapamycin or everolimus so researchers can find safe dosing that may improve age-related biological markers.

What this research studies

You would be a healthy person aged 65–90 who takes short courses of rapamycin or everolimus for about six weeks while the team measures drug levels and biological effects. The open-label, adaptive trial compares daily versus intermittent dosing and adjusts doses to find safe regimens. Researchers will do regular blood tests to measure pharmacokinetics (how the drug moves through your body) and pharmacodynamics (how the drug changes mTOR-related markers such as p70S6K, ribosomal protein S6, Akt, and soluble ICAM-1). The goal is to find dosing that shows biological signs of mTOR inhibition with minimal side effects.

Who could benefit from this research

Good fit: Ideal candidates are generally healthy adults aged 65–90 who can attend study visits and agree to blood draws and short-term medication exposure.

Not a fit: People with active serious illnesses, weakened immune systems, major organ failure, or who cannot stop interacting medications may not be eligible or benefit from this study.

Why it matters

Potential benefit: If successful, the study could identify safe, age-appropriate dosing of these drugs that might slow some age-related declines and guide future treatments.

How similar studies have performed: Animal studies show lifespan and healthspan benefits, and small human trials have suggested immune and biomarker effects, but large-scale proof of anti-aging benefit in people is still limited.
