How do scientists decide which interventions are worth testing in humans for potential health- and/or lifespan benefits?

One way to start is to examine how interventions perform in model organisms such as mice. The Interventions Testing Program (ITP), a federally-funded initiative that began in 2002, tests drugs that may delay mouse aging, with the hope of eventually identifying new longevity interventions for humans. The program aims to take an unbiased approach to interventions testing as possible and to make all data publicly available.

In this episode, Matt goes over recent ITP tests of a broad range of interventions that includes a vasodilator, a beta-blocker, a drug to reverse cyanide poisoning, and more. The drugs are alpha-ketoglutarate, 2,4-dinitrophenol, hydralazine, nebivolol, 16α-hydroxyestriol, sodium thiosulfate, and canagliflozin. He discusses which of these interventions produces lifespan benefits in mice, gender differences in effects, results from previous studies of the interventions, and the importance of examining the life expectancy of controls when evaluating the results of lifespan experiments.

Matt has served on the ITP steering committee since 2012.

Hi, I'm Matt Kaeberlein. I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.

On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!
