We’re developing the first drugs explicitly intended to extend healthspan and lifespan—first in dogs, and then in humans, too.
By quantifying and controlling the mechanisms of pathological aging, we hope to delay the onset & reduce the severity of age-related diseases. More, healthier years.
Backed by the best

Helping dogs live longer, healthier lives
Dogs are our closest companions – in every sense of the word. We co-evolved with dogs and have shared our environment for tens of thousands of years. Understanding and treating pathological dog aging may help us learn more about human aging, too.
