Eplontersen, formerly known as IONIS-TTR-LRx and AKCEA-TTR-LRx, is an investigational LIgand-Conjugated Antisense (LICA) medicine designed to inhibit the production of transthyretin, or TTR protein. The investigational medicine is currently being evaluated in the Phase 3 CARDIO-TTRansform study for hereditary or wild-type transthyretin-mediated amyloid cardiomyopathy (ATTR-CM), a progressive and fatal condition that typically leads to progressive heart failure and often death within three-to-five years from disease onset.

Eplontersen was recently approved in the U.S. for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults, commonly referred to as hATTR-PN or ATTRv-PN under the brand name WAINUA™ (eplontersen). Please see full Prescribing Information.

About Transthyretin-Mediated Amyloid Cardiomyopathy (ATTR-CM)

ATTR-CM is an underdiagnosed and potentially fatal disease. It is caused by the accumulation of misfolded TTR protein in the cardiac muscle. Patients experience ongoing debilitating heart damage resulting in progressive heart failure, which results in death within three to five years from disease onset. ATTR-CM includes both the genetic and wild-type form of the disease. Worldwide, there are an estimated 300,000 – 500,000 patients with ATTR-CM.

Safety and efficacy have not been evaluated by any regulatory authorities for the ATTR-CM indication described.
