What is being tested?
The trial is testing the effectiveness and safety of patisiran for patients with wtATTR amyloidosis who are experiencing nerve damage symptoms. It aims to see if patisiran can improve neurological functions and life quality.
What are the potential side effects?
While not specified here, common side effects of drugs like patisiran may include injection site reactions such as pain or swelling; potential liver issues which could be monitored by blood tests; fatigue; rash; nausea; or other infusion-related reactions.
