Alnylam Pharmaceuticals Reports Fourth Quarter and Full Year 2019 Financial Results and Highlights Recent Period Activity

“In 2019 we saw continued and steady growth of patients on ONPATTRO, and we expect growth to continue in 2020, driven by new patient finding, geographic expansion, and evidence-generating activities. We also believe that our ongoing APOLLO-B Phase 3 study, if positive, can potentially enable future label expansion for patisiran to treat the cardiomyopathy of hereditary and wild-type ATTR amyloidosis. With the early U.S. approval of GIVLAARI in the fourth quarter, Alnylam became a multi-product commercial company, and we are pleased with the strong initial interest from patients, physicians, and payers in the short period since the drug’s approval by the FDA,” said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. “Also in the fourth quarter, we reported positive topline Phase 3 results with lumasiran, Alnylam’s third program in 2019 to achieve positive Phase 3 results, and we’ve initiated the rolling submission of an NDA, setting us up for a potential approval later this year. In addition, in 2020 we look forward to advancing additional late-stage programs closer to the market, namely vutrisiran – with the HELIOS-A and -B studies in ATTR amyloidosis – and, inclisiran and fitusiran with our partners at Novartis and Sanofi, respectively. With continued execution across these and other programs we are confident that by year-end we’ll achieve our Alnylam 2020 goals of building a multi-product, global biopharma company with a deep clinical pipeline to fuel future growth and a robust product engine for sustainable and organic innovation, a profile rarely achieved in our industry.”

Financial Results for the Quarter and Year Ended December 31, 2019

“We believe our fourth quarter and full year 2019 results reflect strong ONPATTRO patient demand and excellent execution by our commercial teams around the world. Notably, we saw significant ONPATTRO new patient growth in the U.S. and EU, and strong initial demand in Japan, together resulting in over 20 percent quarter-on-quarter growth in net product revenues. We expect growth to continue in 2020 and are guiding that we expect to achieve between $285 million and $315 million in ONPATTRO net product revenues for the year. We also look forward to now leveraging our global commercial capabilities for the launch of GIVLAARI,” said Jeff Poulton, Chief Financial Officer of Alnylam. “Our balance sheet remains strong with $1.55B in cash and investments at year-end, enabling continued investments in R&D and commercial execution. Looking forward, we are now focused on achieving a self-sustainable financial profile. The key elements of this transition include top line revenue growth from currently two marketed products – and in the not-too-distant future, potentially up to six marketed products – as well as disciplined investment in our operations.”

Net Product Revenues

• Net product revenues were $55.9 million in the fourth quarter 2019 representing 21% growth from the third quarter 2019 primarily driven by the addition of new patients on therapy and expansion into new markets.
• Net product revenues grew from $12.5 million in 2018 to $166.5 million in 2019 primarily driven by the continued global launch of ONPATTRO during its first full-year on the market.

Net Revenues from Collaborators

• Net revenues from collaborators were $15.7 million in the fourth quarter 2019, an increase from $9.0 million in the fourth quarter 2018 primarily due to revenues from the Regeneron collaboration.
• Net revenues from collaborators were $53.2 million in 2019, a decrease from $62.4 million in 2018 primarily due to a decline in reimbursable activities from the Sanofi Genzyme collaboration, offset by revenues from the Regeneron collaboration.

Research & Development (R&D) and Selling, General & Administrative (SG&A) Expenses

• R&D expenses increased in the fourth quarter and full year 2019 compared to the same periods in 2018 on a GAAP and non-GAAP basis primarily due to increased activity related to the advancement of the Company’s late stage programs.
• SG&A expenses increased in the fourth quarter and full year 2019 compared to the same periods in 2018 on a GAAP and non-GAAP basis primarily due to increases in commercial and medical affairs activities supporting continued investment in the ongoing ONPATTRO launch and the launch of GIVLAARI in late 2019.
• R&D and SG&A expenses on a GAAP basis also increased in the fourth quarter 2019 compared to the same period in 2018 due to an increase in stock-based compensation primarily due to the probability of or achievement of certain performance-based vesting events under outstanding equity awards.

Cash and Investments

• Cash and investments were $1.55 billion at the end of 2019 compared to $1.13 billion at the end of 2018. The increase was due to proceeds received under the Company’s equity offering in the first quarter of 2019 and proceeds received under the collaboration and equity agreements with Regeneron offset by cash used in the Company’s operations.

A reconciliation of GAAP to non-GAAP results is included in the tables of this press release.

2020 Financial Guidance

Full year 2020 financial guidance consists of the following:

• ONPATTRO net product revenues of $285 million – $315 million
• Net revenues from collaborators of $100 million – $150 million
• GAAP R&D and SG&A expenses of $1,180 million – $1,300 million
• Non-GAAP R&D and SG&A expenses of $1,025 million – $1,125 million*
• The Company expects that its current cash, cash equivalents, and marketable debt and equity securities will support company operations for multiple years based on its current operating plans.

*Excludes $155 million – $175 million of stock-based compensation from GAAP R&D and SG&A expenses.

Use of Non-GAAP Financial Measures
This press release contains non-GAAP financial measures, including expenses adjusted to exclude certain non-cash expenses and non-recurring gains outside the ordinary course of the Company’s business. These measures are not in accordance with, or an alternative to, GAAP, and may be different from non-GAAP financial measures used by other companies.

The items included in GAAP presentations but excluded for purposes of determining non-GAAP financial measures for the periods presented in the press release are stock-based compensation expense, a gain on equity securities, a gain on the change in fair value of a liability obligation, and a gain on litigation settlement. The Company has excluded the impact of stock-based compensation expense, which may fluctuate from period to period based on factors including the variability associated with performance-based grants for stock options and restricted stock units and changes in the Company’s stock price, which impacts the fair value of these awards. The Company has excluded the impact of the gain on equity securities, the change in fair value of liability obligation and the gain on litigation settlement because the Company believes these items are one-time events occurring outside the ordinary course of the Company’s business.

The Company believes the presentation of non-GAAP financial measures provides useful information to management and investors regarding the Company’s financial condition and results of operations. When GAAP financial measures are viewed in conjunction with non-GAAP financial measures, investors are provided with a more meaningful understanding of the Company’s ongoing operating performance and are better able to compare the Company’s performance between periods. In addition, these non-GAAP financial measures are among those indicators the Company uses as a basis for evaluating performance, allocating resources and planning and forecasting future periods. Non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. A reconciliation between GAAP and non-GAAP measures is provided later in this press release.

About ONPATTRO^® (patisiran)
ONPATTRO is an RNAi therapeutic that is 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 and Switzerland 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 body’s tissues in order to halt or slow down the progression of the polyneuropathy associated with the disease. For more information about ONPATTRO, visit ONPATTRO.com.

ONPATTRO Important Safety Information
Infusion-Related Reactions
Infusion-related reactions (IRRs) have been observed in patients treated with ONPATTRO. In a controlled clinical study, 19 percent of ONPATTRO-treated patients experienced IRRs, compared to 9 percent 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).

Adverse Reactions
The most common adverse reactions that occurred in patients treated with ONPATTRO were upper respiratory-tract infections (29 percent) and infusion-related reactions (19 percent).

For additional information about ONPATTRO, please see the full Prescribing Information.

About GIVLAARI™ (givosiran)
GIVLAARI is an RNAi therapeutic targeting aminolevulinic acid synthase 1 (ALAS1) that is approved in the U.S. for the treatment of adults with acute hepatic porphyria (AHP). In the pivotal study, GIVLAARI was shown to significantly reduce the rate of porphyria attacks that required hospitalizations, urgent healthcare visits or IV hemin administration at home compared to placebo. GIVLAARI is Alnylam’s first commercially available therapeutic based on its Enhanced Stabilization Chemistry (ESC) GalNAc conjugate technology to increase potency and durability. GIVLAARI is administered via subcutaneous injection once monthly at a dose based on actual body weight and should be administered by a healthcare professional. GIVLAARI works by specifically reducing elevated levels of ALAS1 messenger RNA (mRNA), leading to reduction of toxins associated with attacks and other disease manifestations of AHP. For more information about GIVLAARI, visit GIVLAARI.com.

GIVLAARI Important Safety Information
Contraindications
GIVLAARI is contraindicated in patients with known severe hypersensitivity to givosiran. Reactions have included anaphylaxis.

Anaphylactic Reaction
Anaphylaxis has occurred with GIVLAARI treatment (<1% of patients in clinical trials). Ensure that medical support is available to appropriately manage anaphylactic reactions when administering GIVLAARI. Monitor for signs and symptoms of anaphylaxis. If anaphylaxis occurs, immediately discontinue administration of GIVLAARI and institute appropriate medical treatment.

Hepatic Toxicity
Transaminase elevations (ALT) of at least 3 times the upper limit of normal (ULN) were observed in 15% of patients receiving GIVLAARI in the placebo-controlled trial. Transaminase elevations primarily occurred between 3 to 5 months following initiation of treatment.

Measure liver function tests prior to initiating treatment with GIVLAARI, repeat every month during the first 6 months of treatment, and as clinically indicated thereafter. Interrupt or discontinue treatment with GIVLAARI for severe or clinically significant transaminase elevations. In patients who have dose interruption and subsequent improvement, reduce the dose to 1.25 mg/kg once monthly. The dose may be increased to the recommended dose of 2.5 mg/kg once monthly if there is no recurrence of severe or clinically significant transaminase elevations at the 1.25 mg/kg dose.

Renal Toxicity
Increases in serum creatinine levels and decreases in estimated glomerular filtration rate (eGFR) have been reported during treatment with GIVLAARI. In the placebo-controlled study, 15% of patients receiving GIVLAARI experienced a renally-related adverse reaction. The median increase in creatinine at Month 3 was 0.07 mg/dL. Monitor renal function during treatment with GIVLAARI as clinically indicated.

Injection Site Reactions
Injection site reactions were reported in 25% of patients receiving GIVLAARI in the placebo-controlled trial. Symptoms included erythema, pain, pruritus, rash, discoloration, or swelling around the injection site. One (2%) patient experienced a single, transient, recall reaction of erythema at a prior injection site with a subsequent dose administration.

Drug Interactions
Concomitant use of GIVLAARI increases the concentration of CYP1A2 or CYP2D6 substrates, which may increase adverse reactions of these substrates. Avoid concomitant use of GIVLAARI with CYP1A2 or CYP2D6 substrates for which minimal concentration changes may lead to serious or life-threatening toxicities. If concomitant use is unavoidable, decrease the CYP1A2 or CYP2D6 substrate dosage in accordance with approved product labeling.

Adverse Reactions
The most common adverse reactions that occurred in patients receiving GIVLAARI were nausea (27%) and injection site reactions (25%).

For additional information about GIVLAARI, please see full Prescribing Information.

About LNP Technology
Alnylam has licenses to Arbutus Biopharma LNP intellectual property for use in RNAi therapeutic products using LNP technology.

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 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 Pharmaceuticals
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. Alnylam’s commercial RNAi therapeutic products are ONPATTRO® (patisiran), approved in the U.S., EU, Canada, Japan, and Switzerland, and GIVLAARI™ (givosiran), approved in the U.S. Alnylam has a deep pipeline of investigational medicines, including five product candidates that are in late-stage development. Alnylam is executing 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 1,300 people worldwide and is headquartered in Cambridge, MA.
