CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sep 20, 2022--
Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, today announced that the European Commission (EC) has granted marketing authorization for AMVUTTRA ® (vutrisiran), an RNAi therapeutic for the treatment of hereditary transthyretin-mediated (hATTR) amyloidosis in adult patients with stage 1 or stage 2 polyneuropathy. The EC approval is based on positive 18-month results from the HELIOS-A Phase 3 study, where AMVUTTRA significantly improved the signs and symptoms of hATTR amyloidosis, with more than 50 percent of patients experiencing halting or reversal of their polyneuropathy manifestations.
“On behalf of patients across Europe, we could not be prouder to announce the approval of AMVUTTRA, our second RNAi therapeutic for hATTR amyloidosis. We are committed to delivering continued innovation to people affected by rare, life-limiting conditions where high unmet need still exists. Today’s decision now means we can progress working with health authorities across Europe to achieve responsible and sustainable access arrangements that allow us to bring AMVUTTRA to patients as quickly as possible. Our thanks go to the patients, families, investigators and study staff who have enabled us to reach this significant milestone,” said Kasha Witkos, SVP, Head International Region at Alnylam.
“Although the considerable research into hATTR amyloidosis over the past few years has resulted in a more positive outlook for those diagnosed with the condition, there remain unmet needs in treatment for patients living with this rapidly progressive, multi-system disease”, said Professor David Adams, Head of the Neurology department at Bicêtre hospital AP-HP, University of Paris-Saclay and Lead Investigator for the HELIOS-A Study. “RNAi therapeutics are changing the future of medicine and I am honored to have contributed to these research efforts that have enabled us to bring an innovative new medicine to patients. Results from the HELIOS-A study have shown the potential AMVUTTRA has to benefit patients with hATTR amyloidosis with stage 1 or stage 2 polyneuropathy, whilst also helping reduce treatment burden through subcutaneous dosing once every three months.”
HELIOS-A was a global, randomized, open-label, multicenter, Phase 3 study that evaluated the efficacy and safety of AMVUTTRA across a diverse group of patients with hATTR amyloidosis with stage 1 or stage 2 polyneuropathy. Results of the HELIOS-A study were published in Amyloid in July, 2022.
In the HELIOS-A study, AMVUTTRA met the primary and all secondary endpoints of the study at both 9 months and 18 months, demonstrating reversal in neuropathy impairment and an encouraging safety and tolerability profile. AMVUTTRA demonstrated improvement in the mean change from baseline in modified Neuropathy Impairment Score + 7 (mNIS+7) at 18 months (the primary endpoint for the EU), as compared to external placebo data from the landmark APOLLO Phase 3 study of patisiran.
After 18 months of dosing, the most frequently occurring adverse reactions in AMVUTTRA-treated patients were arthralgia (joint stiffness) and pain in extremity (pain in arms and legs). Other less frequent adverse reactions reported with AMVUTTRA were dyspnea (shortness of breath), injection site reaction and an increase in blood alkaline phosphatase (a liver enzyme).
Vutrisiran was previously granted Orphan Drug Designation in the European Union (EU) and U.S. for the treatment of ATTR amyloidosis and in Japan for transthyretin type familial amyloidosis with polyneuropathy. In June 2022, AMVUTTRA was approved by the U.S. Food and Drug Administration (FDA) for the treatment of the polyneuropathy of hATTR amyloidosis in adults. Vutrisiran is under review by the Brazilian Health Regulatory Agency (ANVISA) and the Japanese Pharmaceuticals and Medical Devices Agency (PMDA).
About AMVUTTRA ® (vutrisiran)
AMVUTTRA is an RNAi therapeutic, which is designed to target and silence specific messenger RNA (mRNA), blocking the production of wild-type and variant transthyretin (TTR) protein before it is made. AMVUTTRA utilizes Alnylam’s Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate delivery platform, designed for increased potency and high metabolic stability to allow for quarterly, and potentially biannual, subcutaneous administration. Vutrisiran is also in development for the treatment of ATTR amyloidosis with cardiomyopathy, which encompasses both hereditary ATTR (hATTR) and wild-type ATTR (wtATTR) amyloidosis.
About hATTR Amyloidosis
Hereditary 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.
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. 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. 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 silencing messenger RNA (mRNA) – the genetic precursors – 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.
IMPORTANT SAFETY INFORMATION
Reduced Serum Vitamin A Levels and Recommended Supplementation
AMVUTTRA treatment leads to a decrease in serum vitamin A levels. Supplementation of approximately, but not exceeding, 2500 IU to 3000 IU vitamin A per day is advised for patients taking AMVUTTRA. Patients should be referred to an ophthalmologist if they develop ocular symptoms suggestive of vitamin A deficiency (e.g., night blindness).
Adverse Reactions
The most frequently occurring adverse reactions in patients treated with AMVUTTRA were arthralgia and pain in extremity. Other commonly reported adverse reactions with AMVUTTRA were dyspnoea, injection site reaction and increase in blood alkaline phosphatase.
