Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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 is 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 is to determine if inotersen can slow or stop the nerve damage caused by TTR deposits. This study will enroll late Stage 1 and early Stage 2 FAP participants. Participants will receive either inotersen or placebo for 65 weeks.
