E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of ISIS 420915 as compared to placebo, given for 65 weeks, as measured by the change from baseline in the modified Neuropathy Impairment Score +7 (mNIS+7) and in the Norfolk Quality of Life-Diabetic Neuropathy (Norfolk QOL-DN) questionnaire total score, in patients with Familial Amyloid Polyneuropathy (FAP). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of ISIS 420915 as compared to placebo based on the change from baseline in the following measures:
• Norfolk QOL-DN questionnaire symptoms domain score in Stage 1 patients and Norfolk QOL-DN questionnaire physical functioning/large fiber neuropathy domain score in Stage 2 patients
• Modified body mass index (mBMI) and body mass index (BMI)
• NIS and modified +7
• NIS+7
• Global longitudinal strain (GLS) by echocardiogram (ECHO) in the ECHO subgroup and in the Cardiomyopathy-ECHO (CM-ECHO) Set
To evaluate the pharmacodynamic (PD) effect of ISIS 420915 as compared to placebo, based on the change from baseline in transthyretin (TTR) and retinol binding protein 4 (RBP4).
To evaluate the safety and tolerability of ISIS 420915.
To evaluate the plasma trough levels of ISIS 420915 in all patients and to evaluate the plasma pharmacokinetic parameters of ISIS 420915 in a subset of patients. |
