|Study Start Date:||December 2012|
|Estimated Study Completion Date:||March 2017|
|Estimated Primary Completion Date:||November 2016 (Final data collection date for primary outcome measure)|
|Active Comparator: ISIS-TTR Rx||
Drug: ISIS-TTR Rx
300 mg ISIS-TTR Rx administered subcutaneously 3 times on alternate days in the first week and then once-weekly for 64 weeks.
|Active Comparator: Placebo||
Placebo administered subcutaneously 3 times on alternate days in the first week and then once-weekly for 64 weeks.
Familial Amyloid Polyneuropathy (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.
ISIS-TTR Rx is an antisense drug that is designed to decrease the amount of mutant and normal TTR made by the liver. It is predicted that decreasing the amount of TTR protein will 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 ISIS-TTR Rx can slow or stop the nerve damage caused by TTR deposits. This study will enroll late Stage 1 and early Stage 2 FAP patients. Patients will receive either ISIS-TTR Rx or placebo for 65 weeks.
