\n\u2013 New Exploratory Findings from 18-Month Analysis of HELIOS-A Suggest that Treatment with Investigational Vutrisiran May Benefit Patients with Hereditary ATTR (hATTR) Amyloidosis and Cardiac Involvement \u2013<\/i>\n<\/p>\n

\n\u2013 Improvements in NT-proBNP and Echocardiographic Parameters Seen in Cardiac Subpopulation \u2013<\/i>\n<\/p>\n

\n\u2013 Reductions in Technetium Uptake Observed in Patients with High Grade Uptake at Baseline \u2013<\/i>\n<\/p>\n

CAMBRIDGE, Mass.–(BUSINESS WIRE)–Alnylam Pharmaceuticals, Inc.<\/a> (Nasdaq: ALNY), the leading RNAi therapeutics company, today announced new positive results from an 18-month analysis of exploratory cardiac endpoints in the HELIOS-A Phase 3 study of vutrisiran, an investigational RNAi therapeutic in development for the treatment of transthyretin-mediated (ATTR) amyloidosis. The 18-month findings show that in a pre-defined cardiac subpopulation, treatment with vutrisiran was associated with improvements in exploratory cardiac endpoints relative to external placebo, including levels of NT-proBNP, a measure of cardiac stress, and a trend towards improvement in echocardiographic parameters. Consistent beneficial effects on cardiac measures were observed in the modified intent-to-treat (mITT) group. Additionally, in a planned cohort of patients from the mITT population, vutrisiran treatment reduced cardiac uptake of technetium on scintigraphy imaging relative to baseline in a majority of assessable patients, including those with Perugini grade \u22652 at baseline, suggesting that patients with the highest degrees of cardiac amyloid burden may recognize benefit from a TTR silencer.\n<\/p>\n

<\/a><\/p>\n

\nThe exploratory findings<\/a> were presented in a late breaking oral session during the annual congress of the Heart Failure Association of the European Society of Cardiology (Heart Failure 2022; May 21-24, 2022). Alnylam previously announced<\/a> that vutrisiran met its primary endpoint and all secondary endpoints at nine months in HELIOS-A, as well as all 18-month secondary endpoints in patients with hereditary ATTR (hATTR) amyloidosis with polyneuropathy, which were presented<\/a> at the Soci\u00e9t\u00e9 Francophone du Nerf P\u00e9riph\u00e9rique (SFNP) annual meeting earlier this year.\n<\/p>\n

\n\u201cWhile the full clinical significance of these findings requires further evaluation, the 18-month exploratory results from HELIOS-A continue to support the potential for vutrisiran to reduce amyloid burden in the heart and suggest that patients with a high degree of cardiac amyloid burden may benefit from this investigational RNAi therapeutic,\u201d said Rena N. Denoncourt, Vice President, TTR Franchise Lead. \u201cWe look forward to seeing data from the APOLLO-B and HELIOS-B studies, which are investigating the efficacy and safety of patisiran and vutrisiran, respectively, to treat the cardiomyopathy of wild-type and hereditary ATTR amyloidosis. We are committed to bringing highly impactful therapeutic options to patients worldwide living with this progressive, multi-system and life-threatening disease.\u201d\n<\/p>\n

\nAt 18 months, patients with pre-existing evidence of cardiac amyloid involvement (baseline LV wall thickness \u22651.3 cm and no aortic valve disease or hypertension in medical history; n=40\/122 vutrisiran; n=36\/77 external placebo group) treated with vutrisiran demonstrated improvement in NT-proBNP levels, with an adjusted geometric fold change of 0.95 compared to 1.93 in the external placebo group (p=0.0004). In the cardiac subpopulation, vutrisiran treatment was also associated with a trend towards improvement (nominal p values) in echocardiographic parameters at Month 18 relative to external placebo, including cardiac output (p=0.0426), LV end-diastolic volume (p=0.0607), global longitudinal strain (p=0.0781) and mean LV wall thickness (p=0.5397).\n<\/p>\n

\nIn a planned cohort of patients from the mITT population, vutrisiran also reduced cardiac uptake of technetium on scintigraphy imaging relative to baseline. 96 percent of assessable patients maintained a stable grade or improved by one grade or greater in the Perugini grading scale at Month 18 relative to baseline. Among vutrisiran-treated patients with Perugini grade \u22651 at baseline, 50 percent showed a one grade or greater improvement at Month 18. Of patients with baseline Perugini grade \u22652 who represent those with evidence of the greatest degree of cardiac amyloid burden evaluated in the analysis, the proportion with improvement in normalized left ventricle total uptake and heart-to-contralateral lung ratio was 100 percent (25\/25) and 77 percent (20\/26), respectively.\n<\/p>\n

\n\u201chATTR amyloidosis is a rapidly progressive disease that can affect multiple organs and tissues, including the heart, nerves and gastrointestinal tract, with potentially fatal outcomes,\u201d said Julian D. Gillmore, M.D., Ph.D., University College London. \u201cThe exploratory cardiac findings from the HELIOS-A Phase 3 study are encouraging as they add to the growing body of data that suggest vutrisiran has the potential to help improve multiple aspects of the disease, including cardiac manifestations that can be life-threatening for these patients.\u201d\n<\/p>\n

\nThe majority of adverse events reported in the vutrisiran arm of HELIOS-A were mild or moderate in severity. As previously reported, there were three study discontinuations in the vutrisiran arm (2.5 percent) by Month 18 due to adverse events, one due to a non-fatal event of heart failure and two due to deaths, none of which were considered related to the study drug. Vutrisiran demonstrated an acceptable cardiac safety profile through 18 months of treatment.\n<\/p>\n

\nVutrisiran is under review by the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), the Brazilian Health Regulatory Agency (ANVISA) and the Japanese Pharmaceuticals and Medical Devices Agency (PMDA). Vutrisiran has been granted Orphan Drug Designation in the U.S. and the European Union (EU) for the treatment of ATTR amyloidosis. Vutrisiran has also been granted a Fast Track designation in the U.S. for the treatment of the polyneuropathy of hATTR amyloidosis in adults. In April, Alnylam announced<\/a> a 3-month extension of the review period for the new drug application for vutrisiran in the U.S. with a new action date under the Prescription Drug User Fee Act (PDUFA) of July 14, 2022. The Company received Orphan Drug Designation in Japan for transthyretin type familial amyloidosis with polyneuropathy. A biannual 50mg dosing regimen is under evaluation within the ongoing randomized treatment extension (RTE) period in the HELIOS-A trial. Vutrisiran is also being evaluated in the HELIOS-B Phase 3 study for the treatment of patients with ATTR amyloidosis with cardiomyopathy, including both hATTR and wild-type ATTR (wtATTR) amyloidosis.\n<\/p>\n

\nAbout Vutrisiran<\/b>\n<\/p>\n

\nVutrisiran is an investigational, subcutaneously administered RNAi therapeutic in development for the treatment of ATTR amyloidosis, which encompasses both hereditary ATTR (hATTR) amyloidosis and wild-type ATTR (wtATTR) amyloidosis. It is designed to target and silence specific messenger RNA, potentially blocking the production of wild-type and variant transthyretin (TTR) protein before it is made. Quarterly, and potentially biannual, administration of vutrisiran may help to reduce deposition and facilitate the clearance of TTR amyloid deposits in tissues and potentially restore function to these tissues. Vutrisiran utilizes Alnylam\u2019s Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate delivery platform, designed for increased potency and high metabolic stability that may allow for infrequent subcutaneous injections. The safety and efficacy of vutrisiran have not been evaluated by the U.S. Food and Drug Administration, European Medicines Agency, or any other health authority.\n<\/p>\n

\nAbout hATTR Amyloidosis<\/b>\n<\/p>\n

\nHereditary transthyretin-mediated (hATTR) amyloidosis is an inherited, progressively debilitating, and fatal disease caused by variants (i.e., mutations) in the TTR gene. TTR protein is primarily produced in the liver and is normally a carrier of vitamin A. Variants in the TTR gene cause abnormal amyloid proteins to accumulate and damage body organs and tissue, such as the peripheral nerves and heart, resulting in intractable peripheral sensory-motor neuropathy, autonomic neuropathy, and\/or cardiomyopathy, as well as other disease manifestations. hATTR amyloidosis, represents a major unmet medical need with significant morbidity and mortality affecting approximately 50,000 people worldwide. The median survival is 4.7 years following diagnosis, with a reduced survival (3.4 years) for patients presenting with cardiomyopathy.\n<\/p>\n

\nAbout HELIOS-A Phase 3 Study
\n
<\/b>HELIOS-A (NCT03759379) is a Phase 3 global, randomized, open-label study to evaluate the efficacy and safety of vutrisiran. The study enrolled 164 patients with hATTR amyloidosis with polyneuropathy at 57 sites in 22 countries. Patients were randomized 3:1 to receive either 25mg of vutrisiran (N=122) via subcutaneous injection once every three months or 0.3 mg\/kg of patisiran (N=42) via intravenous infusion once every three weeks (as a reference comparator) for 18 months. The efficacy results of vutrisiran in HELIOS-A are compared to the placebo group from the landmark APOLLO Phase 3 study, which evaluated the efficacy and safety of patisiran in a patient population similar to that studied in HELIOS-A. The primary endpoint is the change from baseline in mNIS+7 at 9 months. Secondary endpoints at 9 months are the change from baseline in the Norfolk QoL-DN score and the timed 10-MWT. Changes from baseline in NT-proBNP were evaluated as an exploratory endpoint at 9 months. Additional secondary endpoints at 18 months were evaluated in the HELIOS-A study, including change from baseline in mNIS+7, Norfolk QoL-DN, 10-MWT, modified body mass index (mBMI), Rasch-built Overall Disability Scale (R-ODS), and serum transthyretin (TTR) levels. Additional exploratory cardiac endpoint data at the 18-month time point include NT-proBNP, echocardiographic measures and cardiac amyloid assessments with technetium scintigraphy imaging. Following the 18-month treatment period, all patients were eligible to receive vutrisiran for an additional 18 months as part of the randomized treatment extension where they receive either 25mg vutrisiran once quarterly or 50mg vutrisiran once every six months.\n<\/p>\n

\nAbout RNAi
\n
<\/b>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. 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 silencing messenger RNA (mRNA) \u2013 the genetic precursors \u2013 that encode for disease-causing 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
