Abstract
Background: The NEURO-TTRansform trial showed that after 66 weeks of treatment, eplontersen significantly reduced neuropathic impairment and improved quality of life (QoL) in patients with hereditary transthyretin-mediated amyloidosis with polyneuropathy (ATTRv-PN). In this secondary analysis from NEURO-TTRansform, autonomic impairment, and the impact of eplontersen on autonomic impairment progression was evaluated through 85 weeks in patients randomised to eplontersen (n = 144) versus external placebo (n = 60; through Week 66 from the NEURO-TTR trial).
Methods: Change from baseline in modified Neuropathy Impairment Score +7 (mNIS+7) composite score, Norfolk Quality of Life-Diabetic Neuropathy (Norfolk QoL-DN) total score, and the Neuropathy Symptoms and Change (NSC) total score was evaluated. Exploratory assessments were change in autonomic components of these instruments, Composite Autonomic Symptom Score-31 (COMPASS-31) total score, and nutritional status (modified body mass index [mBMI]).
Results: Patients reported profound autonomic dysfunction at baseline. Improvements with eplontersen versus placebo were observed up to Week 66 in autonomic components of mNIS+7, Norfolk QoL-DN, NSC, and mBMI; eplontersen results were sustained up to Week 85, including improvements in COMPASS-31 (Week 81).
Conclusions: Eplontersen demonstrated benefit across multiple measures of autonomic impairment known to progress rapidly and negatively impact QoL without treatment, without deterioration in nutritional status.
期刊介绍：
Amyloid: the Journal of Protein Folding Disorders is dedicated to the study of all aspects of the protein groups and associated disorders that are classified as the amyloidoses as well as other disorders associated with abnormal protein folding. The journals major focus points are:
etiology,
pathogenesis,
histopathology,
chemical structure,
nature of fibrillogenesis;
whilst also publishing papers on the basic and chemical genetic aspects of many of these disorders.
Amyloid is recognised as one of the leading publications on amyloid protein classifications and the associated disorders, as well as clinical studies on all aspects of amyloid related neurodegenerative diseases and major clinical studies on inherited amyloidosis, especially those related to transthyretin. The Journal also publishes book reviews, meeting reports, editorials, thesis abstracts, review articles and symposia in the various areas listed above.
