Alnylam Pharmaceuticals, Inc. (ALNY), the leading RNAi therapeutics company, announced today that the United States Food and Drug Administration (FDA) approved ONPATTRO™ (patisiran) lipid complex injection, a first-of-its-kind RNA interference (RNAi) therapeutic, for the treatment of the polyneuropathy of hereditary transthyretin-mediated (hATTR) amyloidosis in adults. ONPATTRO is the first and only FDA-approved treatment for this indication. hATTR amyloidosis is a rare, inherited, rapidly progressive and life-threatening disease with a constellation of manifestations. In addition to polyneuropathy, hATTR amyloidosis can lead to other significant disabilities including decreased ambulation with the loss of the ability to walk unaided, a reduced quality of life, and a decline in cardiac functioning. In the largest controlled study of hATTR amyloidosis, ONPATTRO was shown to improve polyneuropathy – with reversal of neuropathy impairment in a majority of patients – and to improve a composite quality of life measure, reduce autonomic symptoms, and improve activities of daily living.

“Alnylam was founded on the vision of harnessing the potential of RNAi therapeutics to treat human disease, and this approval heralds the arrival of an entirely new class of medicines. We believe today draws us ever-closer to achieving our Alnylam 2020 goals of becoming a fully integrated, multi-product biopharmaceutical company with a sustainable pipeline,” said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. “With the potential for the sequential launches of several new medicines in the coming years, we believe we have the opportunity to meaningfully impact the lives of people around the world in need of new approaches to address serious diseases with significant unmet medical needs.”
“Today’s historic approval marks the arrival of a first-of-its kind treatment option for a rare and devastating condition with limited treatment options,” said Akshay Vaishnaw, M.D., Ph.D., President of R&D at Alnylam. “We extend our deepest gratitude to the patients who participated in the ONPATTRO clinical trials and their families and caregivers who supported them. We are also grateful for the tireless efforts of the investigators and study staff, without whom this important milestone would not have been possible. We also look forward to working with the FDA to potentially expand the ONPATTRO indication in the future.”
The FDA approval of ONPATTRO was based on positive results from the randomized, double-blind, placebo-controlled, global Phase 3 APOLLO study, the largest-ever study in hATTR amyloidosis patients with polyneuropathy. Results from the APOLLO study were published in the July 5, 2018, issue of The New England Journal of Medicine.
In APOLLO, the safety and efficacy of ONPATTRO were evaluated in a diverse, global population of hATTR amyloidosis patients in 19 countries, with a total of 39 TTR mutations. Patients were randomized in a 2:1 ratio to receive intravenous ONPATTRO (0.3 mg per kg of body weight) or placebo once every 3 weeks for 18 months. The study showed that ONPATTRO improved measures of polyneuropathy, quality of life, activities of daily living, ambulation, nutritional status and autonomic symptoms relative to placebo in adult patients with hATTR amyloidosis with polyneuropathy. The primary endpoint of the APOLLO study was the modified Neuropathy Impairment Score +7 (mNIS+7), which assesses motor strength, reflexes, sensation, nerve conduction and postural blood pressure.
- Patients treated with ONPATTRO had a mean 6.0-point decrease (improvement) in mNIS+7 score from baseline compared to a mean 28.0-point increase (worsening) for patients in the placebo group, resulting in a mean 34.0-point difference relative to placebo, after 18 months of treatment.
- While nearly all ONPATTRO-treated patients experienced a treatment benefit relative to placebo, 56 percent of ONPATTRO-treated patients at 18 months of treatment experienced reversal of neuropathy impairment (as assessed by mNIS+7 score) relative to their own baseline, compared to four percent of patients who received placebo.
- Patients treated with ONPATTRO had a mean 6.7-point decrease (improvement) in Norfolk Quality of Life Diabetic Neuropathy (QoL-DN) score from baseline compared to a mean 14.4-point increase (worsening) for patients in the placebo group, resulting in a mean 21.1-point difference relative to placebo, after 18 months of treatment.
- As measured by Norfolk QoL-DN, 51 percent of patients treated with ONPATTRO experienced improvement in quality of life at 18 months relative to their own baseline, compared to 10 percent of the placebo-treated patients.
- Over 18 months of treatment, patients treated with ONPATTRO experienced significant benefit vs. placebo for all other secondary efficacy endpoints, including measures of activities of daily living, walking ability, nutritional status, and autonomic symptoms.
- The most common adverse events that occurred more frequently with ONPATTRO than with placebo were upper respiratory tract infections and infusion-related reactions. To reduce the risk of infusion-related reactions, patients received premedications prior to infusion.
“FDA approval of ONPATTRO represents an entirely new approach to treating patients with polyneuropathy in hATTR amyloidosis and shows promise as a new era in patient care,” said John Berk, M.D., Associate Professor of Medicine at Boston University School of Medicine and assistant director of the Amyloidosis Center at Boston University School of Medicine. “Given the strength of the APOLLO data, including data showing the possibility of halting or improving disease progression in many patients, ONPATTRO holds tremendous promise for people living with this disease.”
“For years I have witnessed the tragic impact of hATTR amyloidosis on generations of families. Today, we celebrate the FDA approval of ONPATTRO,” said Muriel Finkel, President of Amyloidosis Support Groups. “It’s extremely gratifying to see promising science translate into a treatment option that will allow patients to potentially experience an improvement in their disease and an improvement in their overall quality of life.”
“Today’s approval is significant in so many respects. It means the hATTR amyloidosis community of patients, families, caregivers and healthcare professionals in the United States now has a treatment option that offers renewed hope,” said Isabelle Lousada, Founder and Chief Executive Officer of the Amyloidosis Research Consortium. “With an FDA-approved treatment now available, I am more optimistic than ever that we can increase awareness of this rare disease and encourage more people to get tested and receive the proper diagnosis.”
ONPATTRO is expected to be available for shipment to healthcare providers in the U.S. within 48 hours.
Alnylam is committed to helping people access the medicines they are prescribed and will be offering comprehensive support services for people prescribed ONPATTRO through Alnylam Assist™. Visit AlnylamAssist.com for more information or call 1-833-256-2748.
ONPATTRO was reviewed by the FDA under Priority Review and had previously been granted Breakthrough Therapy and Orphan Drug Designations. On July 27, patisiran received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) for the treatment of hereditary transthyretin-mediated amyloidosis in adults with stage 1 or stage 2 polyneuropathy under accelerated assessment by the European Medicines Agency. The recommended Summary of Product Characteristics (SmPC) for the European Union (EU) includes data on secondary and exploratory endpoints. Expected in September, the European Commission will review the CHMP recommendation to make a final decision on marketing authorization, applicable to all 28 EU member states, plus Iceland, Liechtenstein and Norway. Regulatory filings in other markets, including Japan, are planned beginning in mid-2018.

IMPORTANT SAFETY INFORMATION
Infusion-related reactions (IRRs) have been observed in patients treated with ONPATTRO. In a controlled clinical study, 19% of ONPATTRO-treated patients experienced IRRs, compared to 9% of placebo-treated patients. The most common symptoms of IRRs with ONPATTRO were flushing, back pain, nausea, abdominal pain, dyspnea, and headache.
To reduce the risk of IRRs, patients should receive premedication with a corticosteroid, acetaminophen, and antihistamines (H1 and H2 blockers) at least 60 minutes prior to ONPATTRO infusion. Monitor patients during the infusion for signs and symptoms of IRRs. If an IRR occurs, consider slowing or interrupting the infusion and instituting medical management as clinically indicated. If the infusion is interrupted, consider resuming at a slower infusion rate only if symptoms have resolved. In the case of a serious or life-threatening IRR, the infusion should be discontinued and not resumed.
Reduced Serum Vitamin A Levels and Recommended Supplementation
ONPATTRO treatment leads to a decrease in serum vitamin A levels. Supplementation at the recommended daily allowance (RDA) of vitamin A is advised for patients taking ONPATTRO. Higher doses than the RDA should not be given to try to achieve normal serum vitamin A levels during treatment with ONPATTRO, as serum levels do not reflect the total vitamin A in the body.
Patients should be referred to an ophthalmologist if they develop ocular symptoms suggestive of vitamin A deficiency (e.g. night blindness).
The most common adverse reactions that occurred in patients treated with ONPATTRO were upper respiratory tract infections (29%) and infusion related reactions (19%).

About ONPATTRO™ (patisiran) lipid complex injection
ONPATTRO was approved by the U.S. Food and Drug Administration (FDA) for the treatment of the polyneuropathy of hereditary transthyretin-mediated (hATTR) amyloidosis in adults. ONPATTRO is the first and only RNA interference (RNAi) therapeutic approved by the FDA for this indication. ONPATTRO utilizes a novel approach to target and reduce production of the TTR protein in the liver via the RNAi pathway. Reducing the TTR protein leads to a reduction in the amyloid deposits that accumulate in tissues. ONPATTRO is administered through intravenous (IV) infusion once every 3 weeks following required premedication and the dose is based on actual body weight. Home infusion may be an option for some patients after an evaluation and recommendation by the treating physician, and may not be covered by all insurance plans. Regardless of the setting, ONPATTRO infusions should be performed by a healthcare professional. For more information about ONPATTRO, visit ONPATTRO.com.
About hATTR Amyloidosis
Hereditary transthyretin (TTR)-mediated amyloidosis (hATTR) is an inherited, progressively debilitating, and often fatal disease caused by mutations in the TTR gene. TTR protein is primarily produced in the liver and is normally a carrier of vitamin A. Mutations 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 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. The median survival is 4.7 years following diagnosis. Until now, people living with hATTR amyloidosis in the U.S. had no FDA-approved treatment options.
As part of Alnylam’s commitment to making therapies available to those who may benefit from them, Alnylam Assist will offer a wide range of services to guide patients through treatment with ONPATTRO, including financial assistance options for eligible patients, benefit verification and claims support, and ordering assistance and facilitation of delivery via specialty distributor or specialty pharmacy. Patients will have access to dedicated Case Managers who can provide personalized support throughout the treatment process and Patient Education Liaisons to help patients gain a better understanding of the disease.

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 “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. RNAi therapeutics are a new class of medicines that harness the natural biological process of RNAi. 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 proteins, thus preventing them from being made. This is a revolutionary approach in developing medicines to improve the care of patients with genetic and other diseases.
Alnylam (ALNY) is leading the translation of RNA interference (RNAi) into a whole new class of innovative medicines with the potential to improve the lives of people afflicted with rare genetic, cardio-metabolic, and hepatic infectious diseases. Based on Nobel Prize-winning science, RNAi therapeutics represent a powerful, clinically validated approach for the treatment of a wide range of severe and debilitating diseases. Founded in 2002, Alnylam is delivering on a bold vision to turn scientific possibility into reality, with a robust discovery platform. ONPATTRO, available in the U.S. for the treatment of the polyneuropathy of hereditary transthyretin-mediated (hATTR) amyloidosis in adults, is Alnylam’s first U.S. FDA-approved RNAi therapeutic. Alnylam has a deep pipeline of investigational medicines, including three product candidates that are in late-stage development. Looking forward, Alnylam will continue to execute on its "Alnylam 2020" strategy of building a multi-product, commercial-stage biopharmaceutical company with a sustainable pipeline of RNAi-based medicines to address the needs of patients who have limited or inadequate treatment options. Alnylam employs over 800 people worldwide and is headquartered in Cambridge, MA.
