AstraZeneca and Ionis’ Wainua (eplontersen) has been approved in the US for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults, commonly referred to as hATTR-PN or ATTRv-PN.

Wainua is the only approved medicine for the treatment of ATTRv-PN that can be self-administered via an auto-injector.

Michael J. Polydefkis, M.D., Professor of Neurology at Johns Hopkins University School of Medicine and an investigator in the NEURO-TTRansform study, said: “Many people living with hereditary transthyretin-mediated amyloid polyneuropathy are unable to fully enjoy their lives because of the relentless, progressive and debilitating effects of the disease. Approval of Wainua represents a meaningful advancement in treatment, one that gives those who are living with transthyretin-mediated amyloid polyneuropathy help managing the disease.”

Ruud Dobber, Executive Vice-President, BioPharmaceuticals Business Unit, AstraZeneca, said: “There is an urgent medical need for new therapies for people living with hereditary transthyretin-mediated amyloid polyneuropathy. The US approval of Wainua offers a new treatment option that provides consistent and sustained reduction in serum TTR concentration compared to baseline while halting disease progression and improving quality of life for people living with this debilitating condition.”

Isabelle Lousada, President and CEO, Amyloidosis Research Consortium, said: “People with hereditary transthyretin-mediated amyloid polyneuropathy, and other forms of amyloidosis, are often misdiagnosed since symptoms can mirror other conditions. The path to getting an accurate diagnosis can often be a long, arduous journey and it is critical that a timely and accurate diagnosis is made not only for the individual experiencing symptoms but for their families and loved ones. It is exciting to see new innovations coming through and increased efforts to raise awareness in an area that has often been overlooked or neglected.”

Eplontersen is currently being evaluated in the CARDIO-TTRansform Phase III trial for treatment of 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.
