Takeaway
Patisiran (PN) appears to maintain efficacy with an acceptable safety profile in patients with hereditary transthyretin-mediated amyloidosis with polyneuropathy (ATTRvPN).
Why this matters
ATTRvPN is a rare, progressive disease caused by transthyretin (TTR) gene mutations, whereby misfolded TTR accumulates as amyloid deposits in the organs and tissues; and patisiran (RNA interference agent) inhibits hepatic TTR synthesis, reducing serum levels.
The maintained efficacy and safety profile of PN provides a viable treatment option for patients with ATTRvPN, potentially improving quality of life; however, continued long-term surveillance is necessary for overall safety evaluation.
