The European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended granting a marketing authorisation for Onpattro (patisiran), for the treatment of hereditary transthyretin-mediated amyloidosis (hATTR amyloidosis) in adult patients with stage 1 or stage 2 polyneuropathy (a condition in which the peripheral nerves are damaged). This medicine is expected to affect the course of the disease and improve patient functioning and quality of life.
