CARLSBAD, Calif., May 23, 2024 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) announced today that it will present new subgroup analyses from Ionis and AstraZeneca's Phase 3 NEURO-TTRansform study of WAINUA™ (eplontersen) at the 2024 International Symposium on Amyloidosis (ISA) in Rochester, Minnesota, May 26-30. WAINUA was approved by the U.S. Food and Drug Administration (FDA) in December 2023 for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults, commonly referred to as hATTR-PN or ATTRv-PN.
Notable presentations include:
As part of a global development and commercialization agreement, AstraZeneca and Ionis are commercializing WAINUA for the treatment of ATTRv-PN in the U.S. and are seeking regulatory approval in Europe and other parts of the world.
Eplontersen is currently being evaluated in the Phase 3 CARDIO-TTRansform study for adults with transthyretin-mediated amyloid cardiomyopathy (ATTR-CM), a systemic, progressive and fatal condition that typically leads to progressive heart failure and often death within three-to-five years from disease onset. The CARDIO-TTRansform Phase 3 study is fully enrolled with more than 1,400 patients – making it the largest study in this patient population to date.
About WAINUA™ (eplontersen)
WAINUA™ (eplontersen) is a LIgand-Conjugated Antisense (LICA) medicine designed to inhibit the production of transthyretin, or TTR protein. WAINUA has been approved in the U.S. for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults (also referred to as ATTRv-PN). Please see full Prescribing Information.
INDICATION for WAINUA™ (eplontersen)
WAINUA injection for subcutaneous use 45 mg is indicated for treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults.
IMPORTANT SAFETY INFORMATION for WAINUA™ (eplontersen)

About the NEURO-TTRansform study
NEURO-TTRansform is a global, open-label, randomized trial evaluating the efficacy and safety of eplontersen in patients with ATTRv-PN at week 35, week 66 and week 85. The final analysis comparing eplontersen to an external placebo group was completed at week 66. All patients were then followed on treatment until week 85 and evaluated four weeks after the last dose in an end-of-trial assessment. Following treatment and the end-of-trial assessments, patients were eligible to enter an open-label extension study to continue receiving eplontersen once every four weeks or enter a 20-week post-treatment evaluation period.
About Hereditary Transthyretin-Mediated Amyloid Polyneuropathy (ATTRv-PN)
ATTRv-PN is caused by the accumulation of misfolded mutated TTR protein in the peripheral nerves. Patients with ATTRv-PN experience ongoing debilitating nerve damage throughout their body resulting in the progressive loss of motor functions, such as walking. These patients also accumulate TTR in other major organs, which progressively compromises their function. The damage from misfolded TTR protein accumulation leads to disability within five years of diagnosis and is generally fatal within a decade.
