Alnylam Pharmaceuticals and Gen Sign Distribution Agreement in Turkey for ONPATTRO (patisiran), the First-in-Class Gene-Silencing RNAi Therapeutic -…

Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, and Gen, a GMP-certified pharmaceutical company specializing in rare diseases, today announced an exclusive Distribution Agreement for ONPATTRO, a first-in-class RNAi therapeutic for the treatment of hATTR amyloidosis in adults with Stage 1 or Stage 2 polyneuropathy.

"Our partnership with Gen enables us to extend access to ONPATTRO to patients suffering from hereditary ATTR (hATTR) amyloidosis with polyneuropathy in Turkey where we currently dont have a presence," said Brendan Martin, Vice President and Acting Head of Canada, Europe, Middle East and Africa, Alnylam Pharmaceuticals. "There are a significant number of patients in Turkey who urgently need new treatment options and we are delighted to partner with Gen to bring ONPATTRO to those in need."

Abidin Glms, CEO of Gen stated: "We are proud of our reputation as one of Turkey's leading specialty pharmaceutical companies and are excited to have partnered with Alnylam. Through collaborations with leading international companies, we aim to bring innovative medicines to patients in Turkey in the fastest and most reliable way possible."

Patients in Turkey were among those who participated in the randomized, double-blind, placebo-controlled, global Phase 3 APOLLO study, the largest-ever study in hATTR amyloidosis patients with polyneuropathy, which led to the approval of ONPATTRO in the U.S. and EU in 2018.

About ONPATTRO (patisiran)

ONPATTRO is an RNAi therapeutic that was approved in the United States and Canada for the treatment of the polyneuropathy of hATTR amyloidosis in adults. ONPATTRO is also approved in the European Union, Switzerland and Brazil for the treatment of hATTR amyloidosis in adults with Stage 1 or Stage 2 polyneuropathy, and in Japan for the treatment of hATTR amyloidosis with polyneuropathy. Based on Nobel Prize-winning science, ONPATTRO is an intravenously administered RNAi therapeutic targeting transthyretin (TTR). It is designed to target and silence TTR messenger RNA, thereby blocking the production of TTR protein before it is made. ONPATTRO blocks the production of TTR in the liver, reducing its accumulation in the bodys tissues in order to halt or slow down the progression of the polyneuropathy associated with the disease.

Important Safety Information (ISI) for ONPATTRO

Infusion-Related Reactions

Infusion-related reactions (IRRs) have been observed in patients treated with patisiran. In a controlled clinical study, 19% of patisiran-treated patients experienced IRRs, compared to 9% of placebo-treated patients. The most common symptoms of IRRs with patisiran were flushing, back pain, nausea, abdominal pain, dyspnoea, and headache. Hypotension, which may include syncope, has also been reported as a symptom of IRRs.

To reduce the risk of IRRs, patients should receive premedication with a corticosteroid, paracetamol, and antihistamines (H1 and H2 blockers) at least 60 minutes prior to patisiran 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

Patisiran treatment leads to a decrease in serum vitamin A levels. Patients receiving patisiran should take oral supplementation of approximately 2500 IU vitamin A per day to reduce the potential risk of ocular toxicity due to vitamin A deficiency. Doses higher than 2500 IU vitamin A per day should not be given to try to achieve normal serum vitamin A levels during treatment with patisiran, 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. including reduced night vision or night blindness, persistent dry eyes, eye inflammation, corneal inflammation or ulceration, corneal thickening or corneal perforation).

Adverse Reactions

The most common adverse reactions that occurred in patients treated with patisiran were peripheral oedema (30%) and infusion-related reactions (19%).

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 Alnylams RNAi therapeutic platform, function upstream of todays 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 with the potential to transform the care of patients with genetic and other diseases.

About Alnylam

Alnylam (Nasdaq: ALNY) is leading 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 genetic, cardio-metabolic, hepatic infectious, and central nervous system (CNS)/ocular 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 RNAi therapeutics platform. Alnylams commercial RNAi therapeutic products are ONPATTRO (patisiran), approved in the U.S., EU, Canada, Japan, Brazil and Switzerland, and GIVLAARI (givosiran), approved in the U.S and the EU.
