Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, today announced that the Company will present data from its transthyretin amyloidosis (ATTR) and hypertension programs at the upcoming American Heart Association (AHA) Scientific Sessions 2024, November 16–18, 2024.

Data presentations for the Company’s flagship TTR franchise include new findings from an analysis of the HELIOS-B Phase 3 study of vutrisiran, an RNAi therapeutic in development for the treatment of ATTR amyloidosis with cardiomyopathy (ATTR-CM), as well as interim results from a Phase 1 study evaluating ALN-TTRsc04, a next generation RNAi therapeutic in development for the treatment of ATTR amyloidosis. Full results from the HELIOS-B study, the largest and most contemporary ATTR-CM study to date, were published in The New England Journal of Medicine earlier this year. The study achieved all 10 pre-specified primary and secondary endpoints. In addition, the Company will present a new analysis of the KARDIA-1 Phase 2 study of zilebesiran, an investigational RNAi therapeutic in development for the treatment of hypertension.

About AMVUTTRA^® (vutrisiran)

AMVUTTRA® (vutrisiran) is an RNAi therapeutic that delivers rapid knockdown of mutant and wild‑type transthyretin (TTR), addressing the underlying cause of transthyretin (ATTR) amyloidosis. Administered quarterly via subcutaneous injection, 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. Vutrisiran is also in development for the treatment of ATTR amyloidosis with cardiomyopathy (ATTR-CM), which encompasses both wild-type and hereditary forms of the disease. For more information about AMVUTTRA, including the full U.S. Prescribing Information, visit AMVUTTRA.com.

About ATTR

Transthyretin amyloidosis (ATTR) is an underdiagnosed, rapidly progressive, debilitating and fatal disease caused by misfolded transthyretin (TTR) proteins, which accumulate as amyloid deposits in various parts of the body, including the nerves, heart and gastrointestinal tract. Patients may present with polyneuropathy, cardiomyopathy or both manifestations of disease. There are two different forms of ATTR – 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 200,000-300,000 people worldwide.^1-4

About RNAi

RNAi (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.⁵ Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine.⁶ 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’s RNAi therapeutic platform, function upstream of today’s medicines by potently silencing messenger RNA (mRNA) – the genetic precursors that encode for disease-causing or disease pathway proteins – thus preventing them from being made.⁵ This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.
