CAMBRIDGE, Mass.–(BUSINESS WIRE<\/a>)–Alnylam Pharmaceuticals, Inc.<\/a> (Nasdaq: ALNY), the leading RNAi therapeutics company, today announced the U.S. Food and Drug Administration (FDA) approval of the supplemental New Drug Application (sNDA) for its RNAi therapeutic, AMVUTTRA\u00ae<\/sup> (vutrisiran), for the treatment of the cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis (ATTR-CM) in adults to reduce cardiovascular mortality, cardiovascular hospitalizations and urgent heart failure visits. The approval expands the indication for AMVUTTRA, which now becomes the first and only therapeutic approved by the FDA for the treatment of ATTR-CM and the polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR-PN) in adults.\n<\/p>\n This press release features multimedia.

There is no cure for ATTR-CM, and the deposition of misfolded transthyretin (TTR) fibrils causes irreversible damage over time which can lead to premature death. Today, most patients remain undiagnosed and untreated, and a significant portion of those who are treated with commonly used therapies experience disease progression.\n<\/p>\n \n\u201cThe FDA approval of AMVUTTRA for ATTR-CM marks a pivotal advancement for patients, providing a new and clinically differentiated treatment option that has been shown to improve outcomes, including cardiovascular mortality, and reduce progression for those living with this devastating disease,\u201d said Yvonne Greenstreet, MBChB, Chief Executive Officer of Alnylam. \u201cI would like to extend my deepest gratitude to the patients who participated in our clinical trials, their families and caregivers, the clinical researchers, regulators, and my colleagues at Alnylam who made this approval possible. Today represents a significant milestone in our nearly twenty years of partnership with the ATTR amyloidosis community, but we are not stopping here. We will continue to innovate for patients with ATTR amyloidosis so they can live longer, better, healthier lives.\u201d\n<\/p>\n \nAMVUTTRA is an RNAi therapeutic that works upstream to deliver rapid knockdown of TTR, addressing the disease at its source, with only four convenient subcutaneous doses per year. By rapidly knocking down TTR production, AMVUTTRA substantially decreases deposition of TTR fibrils, which form amyloid and cause irreversible cardiovascular damage and premature death in patients with ATTR-CM.\n<\/p>\n \n\u201cThis FDA approval provides an opportunity to further transform ATTR-CM treatment with a new mechanism of action. The HELIOS-B clinical trial found that vutrisiran allowed patients to live longer, experience fewer hospitalizations, and improve how they function and feel,\u201d said Ronald Witteles, M.D., HELIOS-B Investigator, Professor of Medicine at Stanford University School of Medicine and Co-Director of the Stanford Amyloid Center. \u201cThe trial enrolled patients who mirror the real-world population with this disease, and I am very encouraged by vutrisiran\u2019s ability to demonstrate meaningful clinical benefits across both cardiovascular outcomes and multiple measures of disease progression. This is a very exciting day for patients with this challenging disease.\u201d\n<\/p>\n \nThis approval is based on the HELIOS-B Phase 3 clinical trial which evaluated AMVUTTRA for the treatment of ATTR-CM. The trial achieved statistical significance compared to placebo on all 10 pre-specified primary and secondary endpoints. The results were presented<\/a> at the European Society of Cardiology Congress and simultaneously published in The New England Journal of Medicine<\/i><\/a>. In the overall population, AMVUTTRA reduced the risk of all-cause mortality (ACM) and recurrent cardiovascular (CV) events by 28% during the double-blind treatment period of up to 36 months. Mortality in this population was significantly reduced by 36% through 42 months in a pre-specified secondary endpoint analysis which included up to 36 months of the double-blind period plus six months of open-label extension. In the monotherapy population, AMVUTTRA significantly reduced the risk of ACM and recurrent CV events by 33% in the double-blind period and significantly reduced the risk of mortality by 35% through 42 months. As compared to patients treated with placebo, patients treated with AMVUTTRA also experienced preservation of functional capacity and quality of life, as well as early improvements in biomarkers NT-proBNP and troponin I, which are predictive of cardiovascular outcomes. The safety and tolerability of AMVUTTRA are well-established, as demonstrated in the positive HELIOS-A clinical trial for AMVUTTRA in hATTR-PN which resulted in FDA approval in 2022 and over 5,000 patient-years exposure to-date, globally. In that study, the most common adverse reactions in patients treated with AMVUTTRA were pain in extremity (15%), arthralgia (11%), dyspnea (7%), and vitamin A decreased (7%). No new safety concerns were identified in the HELIOS-B clinical trial of patients with ATTR-CM.\n<\/p>\n \n\u201cDespite recent advances, there remains a significant need for patients living with ATTR-CM and I\u2019ve witnessed, firsthand, the impact that ATTR amyloidosis can have on families, including diminished quality of life and the loss of loved ones,\u201d said Muriel Finkel, President of the Amyloidosis Support Groups. \u201cThe availability of this groundbreaking treatment option is a significant moment for patients living with ATTR amyloidosis. It represents a beacon of hope for our community.\u201d\n<\/p>\n \nAMVUTTRA in hATTR-PN is covered by insurers for ~99% of patients with the majority paying $0 out-of-pocket. Similar broad coverage and out-of-pocket costs are expected in ATTR-CM given comparable payer dynamics and the clinical value demonstrated in the HELIOS-B clinical trial. Alnylam has a proven track record of working closely with payers to ensure broad patient access to our medicines, including pioneering innovative value-based agreements linked to clinical outcomes that ensure value and predictability for payers.\n<\/p>\n \nAlnylam offers multiple support services and resources for patients prescribed its products through Alnylam Assist\u00ae<\/sup>, the only in-house patient support program in ATTR-CM. Alnylam Assist\u00ae<\/sup> is designed to provide one-on-one support for patients and their healthcare teams to help navigate the treatment journey, and includes a Quick Start program that provides eligible patients who encounter coverage delays or delays in treatment with an initial dose at no cost. In addition, Alnylam Assist\u00ae<\/sup> offers support with insurance coverage, financial assistance, and disease and treatment education for a seamless start to the AMVUTTRA treatment experience.

Alnylam remains on track to proceed with additional global regulatory submissions for vutrisiran in 2025.\n<\/p>\n \nVisit AMVUTTRA.com\/attr-cm<\/a> for more information.\n<\/p>\n Investor Webcast Information<\/b><\/p>\n \nAlnylam management will discuss the FDA approval of AMVUTTRA for ATTR-CM via webcast today at 6:00 pmET. A live audio webcast of the call will be available on the Investors section of the Company\u2019s website at www.alnylam.com\/events<\/a>. An archived webcast will be available on the Company\u2019s website approximately two hours after the event.\n<\/p>\n INDICATIONS AND IMPORTANT SAFETY INFORMATION<\/b><\/p>\n Indications<\/b><\/p>\n \nAMVUTTRA\u00ae<\/sup> (vutrisiran) is indicated for the treatment of the:\n<\/p>\n Important Safety Information<\/b><\/p>\n Reduced Serum Vitamin A Levels and Recommended Supplementation<\/b><\/p>\n \nAMVUTTRA treatment leads to a decrease in serum vitamin A levels.\n<\/p>\n \nSupplementation at the recommended daily allowance (RDA) of vitamin A is advised for patients taking AMVUTTRA. Higher doses than the RDA should not be given to try to achieve normal serum vitamin A levels during treatment with AMVUTTRA, as serum vitamin A levels do not reflect the total vitamin A in the body.\n<\/p>\n \nPatients should be referred to an ophthalmologist if they develop ocular symptoms suggestive of vitamin A deficiency (e.g., night blindness).\n<\/p>\n Adverse Reactions<\/b><\/p>\n \nIn a study of patients with hATTR-PN, the most common adverse reactions that occurred in patients treated with AMVUTTRA were pain in extremity (15%), arthralgia (11%), dyspnea (7%), and vitamin A decreased (7%).\n<\/p>\n \nIn a study of patients with ATTR-CM, no new safety issues were identified.\n<\/p>\n For additional information about AMVUTTRA, please see the full <\/b>Prescribing Information<\/b><\/a>.<\/b><\/p>\n About AMVUTTRA\u00ae (vutrisiran)<\/b><\/p>\n \nAMVUTTRA\u00ae<\/sup> (vutrisiran) is an RNAi therapeutic that delivers rapid knockdown of transthyretin (TTR), addressing the underlying cause of transthyretin (ATTR) amyloidosis. Administered quarterly via subcutaneous injection by a healthcare professional, AMVUTTRA is approved and marketed in more than 15 countries for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR-PN) in adults and is approved in the U.S. for the treatment of the cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis (ATTR-CM) in adults to reduce cardiovascular mortality, cardiovascular hospitalizations and urgent heart failure visits.

Patients may present with polyneuropathy, cardiomyopathy, or both manifestations of disease. There are two different forms of ATTR \u2013 hereditary ATTR (hATTR), which is caused by a TTR gene variant and affects approximately 50,000 people worldwide, and wild-type ATTR (wtATTR), which occurs without a TTR gene variant and impacts an estimated 200,000 \u2013 300,000 people worldwide.1-4<\/sup><\/p>\n About RNAi<\/b><\/p>\n \nRNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as \u201ca major scientific breakthrough that happens once every decade or so,\u201d and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines known as RNAi therapeutics is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam\u2019s RNAi therapeutic platform, function upstream of today\u2019s medicines by potently silencing messenger RNA (mRNA) \u2013 the genetic precursors \u2013 that encode for disease-causing or disease pathway proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.\n<\/p>\n About Alnylam Pharmaceuticals<\/b><\/p>\n \nAlnylam Pharmaceuticals (Nasdaq: ALNY) has led the translation of RNA interference (RNAi) into a whole new class of innovative medicines with the potential to transform the lives of people afflicted with rare and prevalent diseases with unmet need.
