About Madrigal

A madrigal is a form of Renaissance choral music known for beautiful harmonies. At Madrigal Pharmaceuticals, our work focuses on restoring balance and harmony to the liver, an organ that performs over 500 different vital functions in the human body.

What began as a small team of researchers in Conshohocken, Pennsylvania, is now a fully integrated biopharmaceutical company with hundreds of employees in the United States and Europe. Madrigal has established a leading clinical development program in MASH.

Our team is united by a single purpose: to lead the fight against MASH.

2008

The Madrigal story began in the early 2000s when founder Rebecca Taub, M.D., began applying her unique understanding of liver biology to explore therapies for MASH and metabolic disease. She identified a previously overlooked molecule – a thyroid hormone receptor-β (THR-β) agonist – and founded Madrigal to unlock its potential.

The overlooked molecule would ultimately become the first approved medication in MASH.

Madrigal is incorporated and initiates Phase 1 trial, focusing on safety and tolerability. This early data provides rationale for THR-β agonism’s potential as a therapeutic strategy for liver disease.

 Against MASH

No family should have to go through the experience of watching a loved one struggle with decompensated cirrhosis or a liver transplant due to MASH. That’s why we aim to develop therapies that will help patients and the health system with this devastating disease.

Our Relentless Pursuit of Innovation

Madrigal has established a leading clinical development program in MASH and delivered the first treatment for people living with MASH in the U.S. and EU. Because of Madrigal’s success, MASH is no longer a ‘graveyard’ for drug innovation, and we continue to study our medication in additional populations with high unmet need.
