In this episode, Rich provides an update on the exciting work of the Interventions Testing Program (ITP), an initiative designed to assess potential life-extending interventions in mice. Rich covers the notable successes like rapamycin, 17⍺-estradiol, and acarbose as well as notable failures like nicotinamide riboside, metformin, and resveratrol, providing valuable lessons about the intricacies of the aging process. Rich delves deep into aging biomarkers and aging rate indicators, unraveling crucial insights into the science of geroprotective molecules. Additionally, Rich discusses some surprising successes of recent molecules tested by the ITP and concludes with an optimistic look at future frontiers, including bridging the gap from mice to humans. We discuss: 0:00:00 - Intro 0:00:50 - An overview of the Interventions Testing Program (ITP) 0:08:51 - How the mice used by the ITP are superior for research relative to mouse models used in most research 0:17:11 - Design of ITP studies, outcomes tested, and metrics of interest 0:29:00 - The process and challenges of drug formulation for mice 0:36:11 - Four drugs identified by the ITP that extends the lifespan of mice 0:43:32 - The success of rapamycin and what it tells us about the biology of aging 0:51:49 - Other measures of healthspan evaluated by the ITP in stage 2 studies 0:59:18 - Distinguishing aging rate indicators from biomarkers of aging 1:01:16 - Aging rate indicators identified through the examination of slow-aging mice 1:15:36 - Why proteomics are essential to understand changes in the cell 1:25:30 - Unraveling aging rate indicators: dose-effect, duration, and future frontiers 1:31:54 - A closer look at aging rate indicators: bridging the gap from mice to humans 1:44:32 - What do laboratory mice die from? 1:48:09 - Distinguishing between a drug that improves an age-sensitive outcome and a drug that improves all aspects of aging 1:48:48 - The ITP study of 17⍺-estradiol: mechanisms of life extension and surprising sex differences 1:58:34 - Unsuccessful drugs studied by the ITP: resveratrol, metformin, and nicotinamide riboside 2:09:13 - Over-the-counter successes in the ITP: meclizine and astaxanthin 2:16:00 - A senolytic drug, fisetin, fails to extend lifespan 2:22:30 - Optimism about future findings -------- About: The Peter Attia Drive is a deep-dive podcast focusing on maximizing longevity, and all that goes into that from physical to cognitive to emotional health.

EPISODE SUMMARY
In this episode of Peter Attia MD, featuring Richard Miller and Peter Attia, 281 ‒ Longevity drugs, aging biomarkers, and updated findings from the Interventions Testing Program explores richard Miller Details ITP Mouse Findings, Aging Rate Indicators, and Failed Drugs Miller describes the ITP as a three-site, roughly $4.5 million per year NIA program that uses genetically heterogeneous UM-HET3 mice, pre-specified statistics, and drug-in-food dosing to screen candidate anti-aging drugs.
