Alnylam Pharmaceuticals Reports Second Quarter 2020 Financial Results and Highlights Recent Period Activity

Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, today reported its consolidated financial results for the second quarter 2020 and reviewed recent business highlights.

“In the second quarter of 2020, the world experienced unprecedented challenges as it continued to confront the COVID-19 pandemic. While the pandemic continues in some countries and states, our global commercialization strategy is now enabling some customer-facing activities to resume in most markets as we enter the third quarter. We are very pleased with our ONPATTRO and GIVLAARI commercial performance in the second quarter, in the face of the ongoing pandemic, and believe it reflects strong demand for our products as well as our team’s unwavering commitment to assure access to these RNAi therapeutics for patients around the world,” said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. “In the quarter, we also continued advancing our robust late-stage pipeline of investigational RNAi therapeutics, where, notably, we presented full results from the ILLUMINATE-A Phase 3 study and completed regulatory filings for lumasiran, and continued enrollment in our APOLLO-B and HELIOS-B Phase 3 studies of patisiran and vutrisiran, respectively. Further, a key business highlight in the second quarter was our completion of a landmark strategic financing collaboration with Blackstone, which we believe will secure our ability to achieve a self-sustainable financial profile without the need for future equity financing. These and other achievements position us to realize our Alnylam 2020 vision of building a multi-product, global biopharma company with a deep clinical pipeline to fuel continued growth and a robust, organic product engine to drive sustainable innovation and further value creation.”

Financial Results for the Quarter Ended June 30, 2020

“We are extremely pleased with our financial results for the second quarter, particularly in the face of these challenging circumstances. Our team’s ability to swiftly adapt to virtual engagement with stakeholders and to support the transition of patients, where needed, to alternate sites of care, in addition to strong international results, led to commercial performance for both ONPATTRO and GIVLAARI that exceeded the initial expectations we communicated in May 2020. As a result, we are further revising our full-year revenue guidance for ONPATTRO, with an increase in the midpoint of our guidance as we narrow the range from $270-$300 million to $280-$300 million,” said Jeff Poulton, Chief Financial Officer of Alnylam. “Outside of our commercial performance, a key business highlight in the second quarter was our achievement of year-over-year improvement in our non-GAAP operating loss versus 2019. Driven by strong top-line year-over-year growth and disciplined investment in our operations, we continue to believe 2019 represents our peak operating loss year as we begin our journey towards a self-sustainable financial profile. In summary, we believe that we’re well positioned to effectively navigate through the pandemic and continue to deliver on the promise of RNAi therapeutics, bringing transformative therapies to patients with serious diseases around the world.”

Net Product Revenues

• Net product revenues were $77.5 million in the second quarter 2020 representing 103% growth from the second quarter 2019 as a result of the addition of new patients on therapy and expansion into new markets for ONPATTRO, as well as the ongoing U.S. commercial launch and initial European launch of GIVLAARI.

Net Revenues from Collaborations

• Net revenues from collaborations were $26.4 million in the second quarter 2020, an increase from $6.5 million in the second quarter 2019, primarily due to increases in revenues recognized from our Regeneron and Vir collaborations.

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

• R&D expenses decreased in the second quarter 2020 compared to the same period in 2019 on a GAAP and non-GAAP basis primarily due to nonrecurring expenses in 2019 from license fees related to the execution of our collaboration agreement with Regeneron, as well as a decrease in expenses associated with material manufactured for clinical trials.
• SG&A expenses increased in the second quarter 2020 compared to the same period in 2019 on a GAAP and non-GAAP basis primarily due to increased investment in commercial and medical affairs activity to support the ongoing launches of ONPATTRO and GIVLAARI and initial launch preparation activities for lumasiran.

Cash and Investments

• Cash, cash equivalents, marketable debt and equity securities, and restricted investments were $1.95 billion at the end of the second quarter 2020 compared to $1.55 billion at the end of 2019. The increase was primarily due to $600.0 million in proceeds received in the second quarter of 2020 from the sale of future royalties and issuance of common stock to Blackstone and its affiliates, partially offset by cash used in our operations to support overall growth.

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

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 expenses, unrealized gain on marketable equity securities, costs associated with our strategic financing collaboration, a gain on contractual settlement, and a gain on the change in fair value of a liability obligation. 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 unrealized gain on marketable equity securities, costs associated with our strategic financing collaboration, the gain on contractual settlement, and a gain on the change in fair value of a liability obligation because the Company believes these items are non-recurring transactions 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 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. 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 (patisiran). 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).

Adverse Reactions

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

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) approved in the United States and Brazil for the treatment of adults with acute hepatic porphyria (AHP). GIVLAARI is also approved in the European Union for the treatment of AHP in adults and adolescents aged 12 years and older. In the pivotal study, givosiran was shown to significantly reduce the rate of porphyria attacks that required hospitalizations, urgent healthcare visits or intravenous 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 aminolevulinic acid synthase 1 (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, 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, Switzerland and Brazil, and GIVLAARI (givosiran), approved in the U.S., EU and Brazil. Alnylam has a deep pipeline of investigational medicines, including six 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 is headquartered in Cambridge, MA. For more information about our people, science and pipeline, please visit www.alnylam.com and engage with us on Twitter at @Alnylam or on LinkedIn.
