Reimagining Health and Disease

More than 20,000 genes make us human. Genes control critical aspects of health and disease — but what controls our genes?

A Flagship Pioneering company, Foghorn Therapeutics is developing therapies based on a system that directs which genes our cells express, and when, where, and in what order.


By manipulating this system with our unique Gene Traffic ControlTM Platform, Foghorn will change how genes turn “on” and “off.” Unlike approaches that edit genes, this novel way of thinking will alter what our DNA has in store for us—and rewrite destiny for millions of people living with disease.


With the Gene Traffic ControlTM Platform, Foghorn is pioneering a new, major class of drug targets to develop unprecedented therapies for cancer and other serious diseases. We have already validated multiple targets, are in the process of developing drug candidates in multiple types of cancer and are beginning to explore other diseases.

a pioneering culture

Foghorn’s focus is on discovering, developing, and delivering revolutionary medicines to our fellow human beings.

We’re building a company that puts people first, never stops trying to battle disease, puts teamwork at the core of everything, and is driven by science to find new ways to think about solving disease.
