`ITEM 1. BUSINESS
`This Annual Report on Form 10-K contains forward-looking statements that involve risks and uncertainties relating to future events and the
`future performance of Regeneron Pharmaceuticals, Inc. ("Regeneron," "Company," "we," "us," and "our"), and actual events or results may
`differ materially from these forward-looking statements. Words such as "anticipate," "expect," "intend," "plan," "believe," "seek," "estimate,"
`variations of such words, and similar expressions are intended to identify such forward-looking statements, although not all forward-looking
`statements contain these identifying words. These statements concern, and these risks and uncertainties include, among others, the nature,
`timing, and possible success and therapeutic applications of our products, product candidates, and research and clinical programs now
`underway or planned, including without limitation sarilumab, dupilumab, fasinumab, and REGN2222; the likelihood and timing of achieving
`any of our anticipated clinical development milestones; unforeseen safety issues resulting from the administration of products and product
`candidates in patients, including serious complications or side effects in connection with the use of our product candidates in clinical trials;
`the likelihood and timing of possible regulatory approval and commercial launch of our late-stage product candidates and new indications for
`marketed products, including without limitation Praluent® (alirocumab) Injection, sarilumab, dupilumab, fasinumab, and REGN2222;
`ongoing regulatory obligations and oversight impacting our marketed products (such as EYLEA® (aflibercept) Injection and Praluent),
`research and clinical programs, and business, including those relating to patient privacy; determinations by regulatory and administrative
`governmental authorities which may delay or restrict our ability to continue to develop or commercialize our products and product candidates;
`competing drugs and product candidates that may be superior to our products and product candidates; uncertainty of market acceptance and
`commercial success of our products and product candidates; our ability to manufacture and manage supply chains for multiple products and
`product candidates; coverage and reimbursement determinations by third-party payers, including Medicare and Medicaid; unanticipated
`expenses; the costs of developing, producing, and selling products; our ability to meet any of our sales or other financial projections or
`guidance, including without limitation capital expenditures and income tax obligations, and changes to the assumptions underlying those
`projections or guidance; the potential for any license or collaboration agreement, including our agreements with Sanofi and Bayer
`HealthCare LLC, to be cancelled or terminated without any further product success; and risks associated with intellectual property of other
`parties and pending or future litigation relating thereto. These statements are made based on management's current beliefs and judgment, and
`the reader is cautioned not to rely on any such statements. In evaluating such statements, shareholders and potential investors should
`specifically consider the various factors identified under Part I, Item 1A. "Risk Factors," which could cause actual events and results to differ
`materially from those indicated by such forward-looking statements. We do not undertake any obligation to update publicly any forward-
`looking statement, whether as a result of new information, future events, or otherwise.
`General
`
`Regeneron Pharmaceuticals, Inc. is a fully integrated biopharmaceutical company that discovers, invents, develops, manufactures, and
`commercializes medicines for the treatment of serious medical conditions. We commercialize medicines for eye diseases, high low-density
`lipoprotein (LDL) cholesterol, and a rare inflammatory condition and have product candidates in development in other areas of high unmet
`medical need, including oncology, rheumatoid arthritis (RA), asthma, atopic dermatitis, pain, and infectious diseases.
`
`Our significant 2015 business highlights include:
`•
`EYLEA (aflibercept) Injection, which is approved by the U.S. Food and Drug Administration (FDA) for use in retinal indications,
`delivered net sales growth of 54% over 2014, and is now the market-leading, branded anti-VEGF therapy in the United States.
`• We, along with our partner Sanofi, received regulatory approval in the United States and Europe for Praluent (alirocumab) Injection for
`the treatment of uncontrolled LDL-cholesterol in certain patients. Praluent has been launched in the United States and certain European
`countries.
`• We reported positive data from three Phase 3 studies of sarilumab in rheumatoid arthritis and submitted a regulatory application to the
`FDA.
`• We reported positive, pivotal, Phase 2b data for dupilumab in the asthma indication and completed enrollment of three Phase 3 studies
`of dupilumab in atopic dermatitis.
`Two of our antibodies advanced to Phase 3 studies: REGN 2222 for the prevention of Respiratory Syncytial Virus (RSV) infection in
`infants; and fasinumab, an antibody against nerve growth factor (NGF), for osteoarthritis pain.
`• We entered into significant new research and development collaborations: a collaboration with Mitsubishi Tanabe Pharma Corporation
`for fasinumab in certain Asian countries and a broad immuno-oncology collaboration with Sanofi.
`Our initiatives in genomics also advanced, enabling us to sequence exomes at the rate of 100,000 per year.

`
`From a company growth perspective, we hired our 4,000th employee, expanded into two new buildings on our Tarrytown, New York
`campus, continued to expand our bulk drug product manufacturing operations in Rensselaer, New York, and continued building out
`and hiring people for our new Limerick, Ireland commercial manufacturing facility.
`• We were named one of the two top employers in the global biopharmaceutical industry by Science, for the fifth consecutive year.
`Our total revenues were $4,103.7 million in 2015, compared to $2,819.6 million in 2014 and $2,104.7 million in 2013. Our net income was
`$636.1 million, or $5.52 per diluted share, in 2015, compared to $338.1 million, or $2.98 per diluted share, in 2014, and $413.7 million, or $3.72
`per diluted share, in 2013. Refer to Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations -
`Results of Operations" below for further details of our financial results.
`
`We currently have three marketed products:
`
`•
`
`•
`
`•
`
`EYLEA (aflibercept) Injection, known in the scientific literature as VEGF Trap-Eye, is available in the United States, European Union
`(EU), Japan, and certain other countries outside the United States for the treatment of neovascular age-related macular degeneration (wet
`AMD), diabetic macular edema (DME), macular edema following retinal vein occlusion (RVO), which includes macular edema
`following central retinal vein occlusion (CRVO) and macular edema following branch retinal vein occlusion (BRVO). EYLEA is also
`available in Japan and the EU for the treatment of myopic choroidal neovascularization (mCNV) and in the United States for the
`treatment of diabetic retinopathy in patients with DME. Bayer HealthCare has additional regulatory applications for EYLEA for
`various indications pending in other countries. We are collaborating with Bayer HealthCare on the global development and
`commercialization of EYLEA outside the United States.
`Praluent (alirocumab) Injection, which is available in the United States where it is indicated as an adjunct to diet and maximally
`tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia or clinical atherosclerotic
`cardiovascular disease (ASCVD), who require additional lowering of LDL cholesterol. In September 2015, the European Commission
`granted marketing authorization of Praluent for the treatment of adult patients with primary hypercholesterolemia (heterozygous
`familial hypercholesterolemia (HeFH) and non-familial) or mixed dyslipidemia as an adjunct to diet: (a) in combination with a statin, or
`statin with other lipid-lowering therapies in patients unable to reach their LDL-cholesterol goals with the maximally-tolerated dose of a
`statin, or (b) alone or in combination with other lipid-lowering therapies for patients who are statin intolerant, or for whom a statin is
`contraindicated. The effect of Praluent on cardiovascular morbidity and mortality has not been determined. We are collaborating with
`Sanofi on the global development and commercialization of Praluent.
`ARCALYST® (rilonacept) Injection for Subcutaneous Use, which is available in the United States for the treatment of Cryopyrin-
`Associated Periodic Syndromes (CAPS), including Familial Cold Auto-inflammatory Syndrome (FCAS) and Muckle-Wells Syndrome
`(MWS), in adults and children 12 years and older.
`
`In February 2015, we and Sanofi entered into an amended and restated ZALTRAP® agreement (Amended ZALTRAP Agreement). Under the
`terms of the Amended ZALTRAP Agreement, Sanofi is solely responsible for the development and commercialization of ZALTRAP (ziv-
`aflibercept) Injection for Intravenous Infusion for cancer indications worldwide. Sanofi bears the cost of all development and commercialization
`activities and reimburses Regeneron for its costs for any such activities. Sanofi pays us a percentage of aggregate net sales of ZALTRAP during
`each calendar year of between 15% to 30%, depending on the aggregate net sales of ZALTRAP in such calendar year. Refer to "Collaboration
`Agreements - Collaborations with Sanofi - ZALTRAP" below for further details of the Amended ZALTRAP Agreement. ZALTRAP is currently
`available in the United States, EU, and certain other countries for treatment, in combination with 5-fluorouracil, leucovorin, irinotecan
`(FOLFIRI), of patients with metastatic colorectal cancer (mCRC) that is resistant to or has progressed following an oxaliplatin-containing
`regimen.
`
`We have 13 product candidates in clinical development, all of which were discovered in our research laboratories. These consist of a Trap-
`based clinical program and 12 fully human monoclonal antibody product candidates, as summarized below. Each of the antibodies in the table
`below was generated using our VelocImmune® technology.

`
`* Sanofi did not opt-in to or elected not to continue to co-develop the product candidate. Under the terms of our agreement, Sanofi is entitled to receive royalties on any future
`sales of the product candidate.
`** Antibodies targeting the PDGF family of receptors and ligands in ophthalmology and all other indications, and antibodies targeting the Ang2 receptor and ligand in
`ophthalmology were previously included in our antibody collaboration with Sanofi. Under the terms of our agreements, Sanofi is entitled to receive potential development
`milestones and royalties on any future sales of the product candidate.
`
`REGN1400, an antibody to ErbB3, REGN1154, an antibody against an undisclosed target, and REGN1193, an antibody to glucagon
`receptor (GCGR), each of which were previously in Phase 1 studies, are no longer in clinical development.
`
`Our core business strategy is to maintain a strong foundation in basic scientific research and discovery-enabling technologies, and to combine
`that foundation with our clinical development, manufacturing, and commercial capabilities. We are executing our long-term objective to build a
`successful, integrated, multi-product biopharmaceutical company that provides patients and medical professionals with innovative options for
`preventing and treating human diseases.
`
`We believe that our ability to develop product candidates is enhanced by the application of our VelociSuite® technology platforms. Our
`discovery platforms are designed to identify specific proteins of therapeutic interest for a particular disease or cell type and validate these targets
`through high-throughput production of genetically modified mice using our VelociGene® technology to understand the role of these proteins in
`normal physiology, as well as in models of disease. Our human monoclonal antibody technology (VelocImmune) and cell line expression
`technologies (VelociMab®) may then be utilized to discover and produce new product candidates directed against the disease target. Our
`antibody product candidates currently in clinical trials were developed using VelocImmune. We continue to invest in the development of
`enabling technologies to assist in our efforts to identify, develop, manufacture, and commercialize new product candidates.
`

`inherited, auto-inflammatory conditions characterized by life-long, recurrent symptoms of rash, fever/chills, joint pain, eye redness/pain, and
`fatigue. Intermittent, disruptive exacerbations or flares can be triggered at any time by exposure to cooling temperatures, stress, exercise, or other
`unknown stimuli.
`
`Net product sales of ARCALYST were $13.5 million in 2015, $14.4 million in 2014, and $17.1 million in 2013.

`
`EYLEA - Ophthalmologic Diseases
`
`Overview
`
`Vascular Endothelial Growth Factor (VEGF) is a naturally occurring protein in the body. Its normal role in a healthy organism is to trigger
`formation of new blood vessels (angiogenesis) supporting the growth of the body's tissues and organs. However, in certain diseases, such as wet
`AMD, it is also associated with the growth of abnormal new blood vessels in the eye, which exhibit abnormal increased permeability that leads
`to edema. Scarring and loss of fine-resolution central vision often results. CRVO is caused by obstruction of the central retinal vein that leads to a
`back-up of blood and fluid in the retina. Release of VEGF contributes to increased vascular permeability in the eye and macular edema. In
`BRVO, a blockage occurs in the blood vessels branching from the main vein draining the retina, resulting in the release of VEGF and consequent
`retinal edema. For centrally involved DME, VEGF-mediated leakage of fluid from blood vessels in the eye results in interference with vision.
`Wet AMD, diabetic retinopathy (which includes DME), and RVO are three of the leading causes of adult blindness in the developed world. In
`these conditions, severe visual loss is caused by neovascular proliferation and/or retinal edema.
`
`EYLEA is a recombinant fusion protein, consisting of portions of human VEGF receptors 1 and 2 extracellular domains fused to the Fc
`portion of human IgG1 and formulated as an iso-osmotic solution for intravitreal administration. EYLEA acts as a soluble decoy receptor that
`binds VEGF-A and placental growth factor (PlGF) and thereby can inhibit the binding and activation of these cognate VEGF receptors. EYLEA
`is specially purified and contains iso-osmotic buffer concentrations, allowing for injection into the eye.
`
`Neovascular Glaucoma
`
`NVG is a secondary glaucoma triggered by the formation of new blood vessels (neovascularization) on the iris and the anterior chamber
`angle. Neovascularization restricts aqueous outflow and consequently elevates intraocular pressure (IOP). NVG is a serious condition that may
`lead to permanent loss of vision, a persistently painful eye, and, especially in the advanced stages, is unlikely to respond to treatment. NVG is
`caused by eye diseases leading to retinal ischemia, mainly CRVO, proliferative diabetic retinopathy (PDR), and ocular ischemic syndrome (OIS).
`
`NVG meets the criteria for an orphan indication in Japan where the estimated number of NVG patients is 30,000 to 40,000. In the second
`quarter of 2015, Bayer HealthCare initiated a Phase 3 study in Japan to assess the efficacy and safety of intravitreal administration of aflibercept
`in comparison to sham treatment on the change in IOP in patients with NVG.

`
`Praluent for LDL cholesterol reduction
`
`Overview
`
`Elevated LDL cholesterol ("bad cholesterol") level is a validated risk factor leading to cardiovascular disease. Statins are a class of drugs that
`lower LDL cholesterol (LDL-C) through inhibition of HMG-CoA, an enzyme regulating the early and rate-limiting step in cholesterol
`biosynthesis that ultimately results in an increase in LDL receptors to increase the uptake of plasma LDL lipoproteins. Similar to statins, PCSK9
`impacts the number of available LDL receptors and therefore plays a key role in modulating LDL-C levels in the body. PCSK9 is a secreted
`protein that binds to and induces the destruction of the LDL receptor, thereby interfering with cellular uptake and increasing circulating levels of
`LDL cholesterol. In a landmark study published in The New England Journal of Medicine in March 2006, patients with lower than normal
`PCSK9 levels due to a genetic abnormality not only had significantly lower levels of LDL-C, but also a significant reduction in the risk of
`coronary heart disease (CHD). We used our VelocImmune technology to generate a fully human monoclonal antibody inhibitor of PCSK9, called
`Praluent, that is intended to lower LDL cholesterol.

`Phase 3 ODYSSEY Program. We and Sanofi initiated the global Phase 3 ODYSSEY program for Praluent in 2012. The ODYSSEY program
`consists of more than 25,000 patients, and includes clinical trials evaluating the effect of Praluent, dosed every two weeks, on lowering LDL
`cholesterol. In addition, the potential of Praluent to demonstrate cardiovascular benefit is being prospectively assessed in the ongoing 18,000-
`patient ODYSSEY OUTCOMES trial, which is fully enrolled and is expected to be completed in 2017. LDL cholesterol reduction is the primary
`efficacy endpoint for initial regulatory filings. Additionally, the ODYSSEY program includes two trials of Praluent dosed every four weeks,
`ODYSSEY CHOICE I and ODYSSEY CHOICE II. Patients in the ODYSSEY CHOICE I trial received Praluent 300 milligrams (mg) (most in
`combination with statins) every four weeks and patients in the CHOICE II trial received Praluent 150 mg monotherapy and in combination with
`non-statin lipid lowering therapy every four weeks.
`
`In 2013, we and Sanofi reported data from the ODYSSEY MONO trial, which evaluated the efficacy and safety of Praluent monotherapy
`versus ezetimibe monotherapy in patients with primary hypercholesterolemia. In 2014, we and
