What is ONPATTRO® (patisiran) and how does it work?

In individuals with hATTR amyloidosis, a genetic mutation causes a protein called transthyretin (TTR) to misfold and build up into clusters (amyloid deposits) throughout the body, leading to symptoms of the disease.

ONPATTRO is a medicine that treats the polyneuropathy of hATTR amyloidosis in adults. It addresses the underlying cause of the disease by decreasing the production of TTR protein. This results in a reduction of amyloid deposits.
