Brief summary

This study evaluates the safety and tolerability of extended dosing with IONIS-TTR Rx in patients with Familial Amyloid Polyneuropathy.

Detailed description

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. IONIS-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. This study evaluates the safety and tolerability of extended dosing with IONIS-TTR Rx in patients with Familial Amyloid Polyneuropathy.

A TEAE is defined as an adverse event with an onset that occurs after receiving study drug. An SAE is any untoward medical occurrence that at any dose that results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, leads to a congenital anomaly/birth defect, or is an important medical event. TEAEs considered related to the study drug as assessed by the Investigator are reported.

Percentage of Participants With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs, and TEAEs Related to Study Drug

An adverse event (AE) is any unfavorable and unintended sign (including a clinically significant abnormal laboratory finding, for example), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE is considered related to the investigational drug product. A TEAE is defined as an adverse event with an onset that occurs after receiving study drug. An SAE is any untoward medical occurrence that at any dose that results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, leads to a congenital anomaly/birth defect, or is an important medical event. TEAEs considered related to the study drug as assessed by the Investigator are reported.

Time frame: From first dose of study drug up to 3 months post treatment period of 260 weeks (Up to approximately 272 weeks)

Percentage of Participants With Change From Baseline in the Polyneuropathy Disability (PND) Score

PND score is defined as I = sensory disturbances in limbs without motor impairment; II = difficulty walking without the need of a walking aid; III = one stick or one crutch required for walking; IV = two sticks or two crutches needed. V = wheelchair required or patient confined to bed. The change from Baseline values have been categorized as: improved, not changed, worsened, and unknown. Percentage of participants with changes from Baseline are presented category-wise in this outcome measure. Only categories with at least one participant with event are reported.

Time frame: Baseline, Weeks 78 and 156 and at the end of each subsequent treatment year (Week 52 of each year)

Population: FAS included all enrolled participants who received at least 1 injection of inotersen in this study (CS3) and who had at least 1 post-baseline efficacy assessment for the mNIS+7 score or Norfolk QoL-DN questionnaire total score collected after CS3 Study Day 1. Number analyzed is the number of participants with data available for analysis at the given time point for the specified category.
