Ionis announces FDA acceptance of New Drug Application for eplontersen for the treatment of hereditary transthyretin-mediated amyloid polyneuropathy (ATTRv-PN)

Industry News In The News

CARLSBAD, Calif., March 7, 2023 /PRNewswire/ -- Ionis Pharmaceuticals (Nasdaq: IONS) today announced that the U.S. Food and Drug Administration (FDA) has accepted for review a New Drug Application (NDA) for eplontersen, an investigational antisense medicine for the treatment of people living with hereditary transthyretin-mediated amyloid polyneuropathy (ATTRv-PN). The application has been given a Prescription Drug User Fee Act (PDUFA) action date of Dec. 22, 2023.

In its acceptance letter, the FDA stated that it has not identified any review issues and did not make any additional data requests. The FDA also noted that it is not planning to hold an advisory committee meeting to discuss the application.

Patients with ATTRv-PN experience ongoing debilitating nerve damage throughout their body resulting in the progressive loss of motor function. These patients accumulate TTR in other major organs, which progressively compromises their function and eventually leads to death within five to fifteen years of disease onset.

"We are excited by today's FDA acceptance of our NDA filing as it brings Ionis and our partner, AstraZeneca, one step closer to making eplontersen available to patients with ATTR polyneuropathy," said Eugene Schneider, M.D., executive vice president and chief clinical development officer at Ionis. "Significant reductions in TTR protein levels were observed during the NEURO-TTRansform 35-week interim analysis. Overall, the interim analysis demonstrated eplontersen has the potential to make a positive impact on disease progression and improve quality of life in a substantial number of patients."
