FAP is a rare, hereditary disease caused by mutations in the transthyretin (TTR) protein. TTR is made by the liver and secreted into the blood. TTR mutations cause it to misfold and deposit in multiple organs causing FAP.
Inotersen (also known as ISIS 420915) is an antisense drug that was designed to decrease the amount of mutant and normal TTR made by the liver. It was predicted that decreasing the amount of TTR protein would result in a decrease in the formation of TTR deposits, and thus slow or stop disease progression.
The purpose of this study was to determine if inotersen could slow or stop the nerve damage caused by TTR deposits. This study enrolled late Stage 1 and early Stage 2 FAP participants. Participants received either inotersen or placebo for 65 weeks.
