Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of inotersen given for 65 weeks in participants with Familial Amyloid Polyneuropathy (FAP).

Condition or Disease Intervention/Treatment Phase
Phase 2/Phase 3

Detailed Description

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 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.

    Outcome Measures

    Primary Outcome Measures

    1. Change From Baseline In The Modified Neuropathy Impairment Score (mNIS) +7 Composite Score at Week 66 [Baseline and Week 66]

      The mNIS+7 composite score is a measure of neurologic impairment that evaluates muscle weakness, sensation, reflexes, nerve conduction, and autonomic function. The mNIS+7 Composite Score has a range of -22.32 to 346.32 and a higher mNIS+7 composite score indicates lower function.

    2. Change From Baseline In The Norfolk Quality Of Life Diabetic Neuropathy (QoL-DN) Questionnaire at Week 66 [Baseline and Week 66]

      The Norfolk QoL-DN score is a measure of physical function/large fiber neuropathy, symptoms, activities of daily living, small fiber neuropathy, and autonomic neuropathy. The Norfolk QoL-DN total score has a range of -4 to 136, and a higher Norfolk QoL-DN score indicates poorer QoL.

    Secondary Outcome Measures

    1. Change From Baseline In The Norfolk QoL-DN Questionnaire Symptoms Domain Score at Week 66 [Baseline and Week 66]

      The Norfolk QoL-DN symptoms score is a sub-score of the total Norfolk QoL-DN Questionnaire. The Norfolk QoL-DN symptoms domain score has a range of 0-32, and a higher Norfolk QoL-DN score indicates poorer QoL.

    2. Change From Baseline In The Norfolk QoL-DN Questionnaire Physical Functioning/Large Fiber Neuropathy Domain Score at Week 66 [Baseline and Week 66]

      The Norfolk QoL-DN physical functioning/large fiber neuropathy domain score is a sub-score of the total Norfolk QoL-DN Questionnaire. The Norfolk QoL-DN physical function/large fiber neuropathy domain score has a range of -4 to 56, and a higher Norfolk QoL-DN domain score indicates poorer QoL.

    3. Change From Baseline In Modified Body Mass Index (mBMI) at Week 65 [Baseline and Week 65]

      The mBMI is the BMI multiplied by the serum albumin g/L

    4. Change From Baseline In Body Mass Index (BMI) at Week 65 [Baseline and Week 65]

    5. Change From Baseline in Neuropathy Impairment Score (NIS) at Week 66 [Baseline and Week 66]

      The NIS score is a measure of neurologic impairment. The NIS Score has a range of 0 to 244 and a higher NIS score indicates lower function.

    6. Change From Baseline in Modified +7 at Week 66 [Baseline and Week 66]

      The Modified +7 score is a version of the NIS score that is a measure of neurologic impairment. The Modified +7 Score has a range of -22.32 to 102.32 and a higher NIS score indicates lower function.

    7. Change From Baseline in NIS+7 at Week 66 [Baseline and Week 66]

      The NIS+7 score is a version of the NIS score that is a measure of neurologic impairment. The NIS+7 Score has a range of -26.04 to 270.04 and a higher NIS score indicates lower function.

    8. Change From Baseline in Global Longitudinal Strain (GLS) by Echocardiogram (ECHO) at Week 65 in the CM-ECHO Set [Baseline and Week 65]

      GLS by ECHO is a measure of cardiac systolic function

    9. Change From Baseline in Global Longitudinal Strain (GLS) by Echocardiogram ECHO at Week 65 in the ECHO Subgroup [Baseline and Week 65]
