Onpattro is a medicine used to treat nerve damage caused by hereditary transthyretin (hATTR) amyloidosis, a disease in which abnormal proteins called amyloids build up in tissues around the body including around the nerves. (europa.eu)
In patients with hATTR amyloidosis, a protein called transthyretin which circulates in the blood is defective and breaks easily. (europa.eu)
