Summary

This Phase 2 trial is testing whether the drug sirolimus can slow aging in adults aged 65 to 80. Ten participants will be randomly assigned to receive sirolimus or standard care, and researchers will measure aging biomarkers like walking speed and cellular changes after one year. The goal is to see if sirolimus can reduce age-related decline and prevent chronic diseases.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Sirolimus (a drug that may slow aging at the cellular level)
What this could lead to
If it works, this could point toward a treatment that delays aging and reduces chronic diseases like skin cancer.
What could go wrong
This is a very small early-phase trial with only 10 participants, so results may not apply to everyone. Sirolimus is an immunosuppressant and can have side effects like increased infection risk.
