Rapa-CV Substudy E

Effect of mTOR Inhibition and Other Metabolism Modulating Interventions on the Elderly: Immune, Cognitive, and Functional Consequences (Substudy E – RAPA cMRI with LGE)

Purpose of this Study

Rapamycin is a medication  approved by the US Food and Drug Administration (FDA) as an immunosuppressant drug (a drug that reduces the human body’s normal immune response) used to prevent rejection in organ transplantation; it is especially useful in kidney transplants. Rapamycin reduces the effects of mTOR, which is a substance that controls growth of cells in your body.  Rapamycin that has been shown to increase lifespan in laboratory animals.

The safety of Rapamycin in humans has been tested in prior research studies alone or in combination with another drug, to evaluate effects on physical function, cognitive function and immune health.

This new study will help find out what effects, Rapamycin has on people who take the drug and the drug’s effect on heart function, heart muscle stiffening, and other effects on circulation.
