Patisiran – 2018 Pipeline Review

Hereditary transthyretin (TTR)-mediated amyloidosis (hATTR) is an inherited and debilitating disease that is characterized by mutations in the TTR gene. These gene mutations can cause accumulation of abnormal amyloid proteins in body organs and tissue, leading to damage of these areas, such as the peripheral nerves. Peripheral, autonomic, or cardiomyopathy can result from this accumulation and damage, making this a progressive and potentially fatal disease. Currently, liver transplantation is the only available treatment option for hATTR amyloidosis.

Alnylam Pharmaceuticals has utilized RNAi technology to develop patisiran, an investigational antisense RNAi oligonucleotide, for the treatment of hATTR amyloidosis (Familial Amyloid Neuropathies). Patisiran received Priority Review designation by the FDA on February 1, 2018 and has a PDUFA action date set for August 11, 2018.
