Market-leading anti-VEGF approved in more than 100 countries for the treatment 
of key blindness-causing retinal conditions including wet age-related macular 
degeneration (AMD) and diabetic macular edema (DME). 

EYLEA global net sales exceeded $5 billion in 2016. In the United States, EYLEA net sales increased 

24% to $3.32 billion for the full year 2016 from $2.68 billion for the full year 2015. Outside of the United 

States, where our collaborator Bayer HealthCare commercializes EYLEA, net sales were $1.87 billion in 

2016, compared to $1.41 billion in 2015. Regeneron recognized $649 million from its share of net profit 

outside the United States in 2016, compared to $467 million in 2015.

“We’re proud that EYLEA has helped many patients over the last 
several years. We continue to work on new innovations for people 
with serious vision-threatening diseases in an effort to further 
improve outcomes for these patients.” 

— Robert L. Vitti, MD, Vice President and Head of Ophthalmology

In 2017, we continue to enroll patients in our ongoing Phase 3 study of EYLEA in non-proliferative diabetic 

retinopathy, a common eye disease that impacts many people with diabetes. In addition to this new indication, 

we are exploring EYLEA in combination with nesvacumab, an anti-angiopoietin 2 antibody, in two fully enrolled 

Phase 2 trials — RUBY in DME and ONYX in wet AMD. In 2016, we discontinued the development of another EYLEA 

combination therapy, aflibercept + rinucumab, an anti–platelet-derived growth factor receptor beta (anti-PDGFR-beta) 
antibody, which did not demonstrate improvement in best corrected visual acuity (BCVA) compared to aflibercept 

monotherapy in our Phase 2 CAPELLA study. Though pre-clinical data for the co-formulation of aflibercept and nesvacumab 

are more supportive, EYLEA sets a very high efficacy bar in the treatment of these disease indications.

Monoclonal antibody targeting PCSK9 (proprotein convertase 
subtilisin/kexin type 9) available in two doses, allowing for 
dose adjustment based on patients’ LDL-C–lowering needs. 

Praluent completed its first full year on the market in 2016, with $116 million in global net sales. Praluent 

is a PCSK9 inhibitor approved by the FDA as adjunct to diet and maximally tolerated statin therapy for the 

treatment of heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease 

in adults who require additional lowering of LDL-C (often referred to as “bad cholesterol”). The effect of 

Praluent on cardiovascular morbidity and mortality has not been determined. 

The ongoing ODYSSEY OUTCOMES clinical trial program, which is evaluating the potential of Praluent to 

prevent heart attacks, stroke and cardiac death, reached full enrollment in 2015, with more than 18,000 patients 

at over 2,000 study centers. Two prespecified interim analyses were performed by an independent Data 

Monitoring Committee in 2016 — the first, a futility analysis when 50% of cardiovascular events had occurred, and 

the second analysis, for both futility and overwhelming efficacy, when 75% of cardiovascular events had occurred. 

The trial continued as planned following both analyses, and we expect to complete the study in late 2017. 

We continue to be involved in patent litigation with Amgen related to Praluent. In 2016, a District Court jury ruled 

against us, upholding the validity of Amgen’s patents. In early 2017, the District Court granted a permanent 
injunction requested by Amgen, preventing the marketing, selling, or commercial manufacturing of Praluent in 

the United States. We have appealed both of these decisions to the U.S. Court of Appeals for the Federal 

Circuit, which hears all biopharmaceutical patent litigation appeals, and the court has stayed (suspended) 

the permanent injunction for Praluent that was granted by the District Court, pending appeal. This stay 

ensures that Praluent will continue to be available to patients during the ongoing appeal process. We 

strongly believe that the controlling law and facts support our position that Amgen’s asserted patent 

claims are invalid. We look forward to pursuing our appeal over the coming months.

First-in-class monoclonal antibody that treats moderate-to-severe atopic dermatitis (AD) by blocking IL-4 and 
IL-13, two key cytokines involved in allergic diseases.

  Dupixent patient

Dupixent has been approved in the United States and is under regulatory review in the European Union for the treatment of atopic 

dermatitis (AD). It is also being studied in other allergic conditions including asthma, nasal polyps, and eosinophilic esophagitis.

In March of 2017, Dupixent was approved by the FDA for the treatment of moderate-to-severe AD in adults whose disease is not 

adequately controlled with topical prescription therapies or for whom those therapies are not advisable. Dupixent can be used with 

or without topical corticosteroids. With our collaborator Sanofi, we launched the product to the commercial market shortly following 

approval. We are excited to provide this first-in-class medicine to adult patients who, up until the approval of Dupixent, had no 

FDA-approved biologic therapies to treat their uncontrolled moderate-to-severe AD. Additionally, in December of 2016, the European 

Medicines Agency (EMA) accepted for review the Marketing Authorization Application (MAA) for Dupixent for the treatment of 

moderate-to-severe AD in adults who are candidates for systemic therapy. We expect a decision from the EMA later in 2017.

In 2016, we reported positive data from three Phase 3 trials of Dupixent (LIBERTY AD SOLO 1, LIBERTY AD SOLO 2, and LIBERTY 

AD CHRONOS) in adult patients with moderate-to-severe AD. In these studies, treatment with Dupixent as monotherapy or as 

concomitant treatment with topical medications significantly improved measures of overall disease severity, skin clearing, and itching.

We are also studying dupilumab in pediatric patients with moderate-to-severe AD, and have been granted Breakthrough Therapy 
designation by the FDA for a subset of pediatric patients with moderate-to-severe AD. We began a Phase 3 trial in adolescents 

(aged 12 to 17 years) with moderate-to-severe AD in the first quarter of 2017, and we expect to initiate a trial in children (aged 6 to 11 

years) with severe AD later in 2017.

Our second pivotal study for the treatment of asthma, LIBERTY ASTHMA QUEST, is fully enrolled, with data expected in the second 

half of 2017. We plan to submit a U.S. regulatory filing for dupilumab in this indication by year-end 2017. In the second quarter of 2017, 

we anticipate beginning enrollment of a Phase 3 trial in uncontrolled, persistent asthma in children (aged 6 to 11 years).

Progress continues on our other indications as well. We have begun enrolling patients with nasal polyps in two Phase 3 trials, and 

expect to begin enrolling patients with food allergies in a Phase 2 trial in the second half of 2017. We also expect Phase 2 data from 

our ongoing trial in patients with eosinophilic esophagitis in the second half of 2017.

IL-6R antibody under U.S. and EU regulatory review for 
the treatment of rheumatoid arthritis (RA). Kevzara has 
been approved in Canada.

In 2016, we reported positive data from the Phase 3 SARIL-RA-MONARCH monotherapy 

study, which met its primary endpoint by demonstrating that Kevzara was superior to 
Humira® (adalimumab) in improving signs and symptoms in adults with active RA who were 
inadequate responders to, intolerant of, or inappropriate candidates for methotrexate. 

It was the first time a subcutaneously delivered IL-6 receptor blocker demonstrated 

superiority over adalimumab monotherapy in RA.

In 2016, the EMA accepted for review the MAA for sarilumab, and an application for marketing 

approval for sarilumab was submitted in Japan. In the United States, we, along with our 

collaborator Sanofi, submitted the U.S. Biologics License Application (BLA) for Kevzara in 

November 2015, and were assigned a Prescription Drug User Fee Act (PDUFA) date of 

October 30, 2016. On October 28, 2016, we received a Complete Response Letter (CRL) from 

the FDA related to a Sanofi manufacturing facility. In early 2017, after the facility completed a 

successful FDA re-inspection, we resubmitted the Kevzara BLA. We expect an FDA decision in 

the second quarter of 2017. Finally, in February 2017, Kevzara received approval and was 
launched in the commercial market in Canada for the treatment of moderately to severely 

active RA in adults who have had an inadequate response or intolerance to one or more 

biologic or non-biologic disease-modifying antirheumatic drugs (DMARDs). 

“RA impacts every aspect of 

my life and when its 

uncontrolled it makes me feel 

like I can’t do anything I love. 

I’m so glad people continue 

to develop new treatments so 

I can go back to doing the 

things I love – playing with my 

five grandchildren, quilting, 

and cooking.”

Fully human monoclonal antibody being investigated for 
the prevention of serious lower respiratory tract infections 
associated with respiratory syncytial virus (RSV).

In 2016, we continued enrollment of the Phase 3 NURSERY-preterm trial that is evaluating the efficacy, safety, 

pharmacokinetics (PK) and immunogenicity of suptavumab in infants born at a gestational age of 35 weeks or 

less who are younger than 6 months. We expect to report topline data from this trial in the second half of 2017.

FASINUMAB

Nerve growth factor–targeting antibody being evaluated for novel, 
non-opioid approach to certain chronic pain conditions.

In 2016, we announced a global collaboration to develop and commercialize fasinumab with Teva, a leading 

global pharmaceutical company with expertise in pain therapeutics. Under a previously announced collaboration 

agreement with Regeneron, Mitsubishi Tanabe Pharma Corporation (MTPC) has exclusive development and 

commercial rights to fasinumab in Japan, Korea, and nine other Asian countries. We believe both Teva and 
MTPC will be strong partners in potentially bringing fasinumab to the market and those patients in need.

We launched a large Phase 3 clinical program studying fasinumab for pain due to osteoarthritis (OA) in 2016 

and continue to enroll patients. The FDA placed our Phase 2 trial in chronic lower back pain (CLBP) on hold 

in the fourth quarter of 2016, following the observation of a case of rapidly progressing OA in a patient who 

was receiving high-dose fasinumab and had a history of advanced OA of the knee. This event prompted 

an unplanned interim analysis of the study, which had completed 70% of its targeted enrollment and 

showed clear evidence of efficacy and improvement in pain scores for all dosing groups. Following 

communications with the FDA, we plan to continue development of fasinumab in CLBP without 

advanced OA. In collaboration with Teva, we expect to initiate a Phase 3 trial in 2017.

Our portfolio in this rapidly developing field grew in 2016, through 
both new product candidates and new indications for existing 
candidates, supported by our ongoing collaboration with Sanofi.

Our growing clinical-stage immuno-oncology pipeline now includes three antibodies: a PD-1 

inhibitor, a CD20xCD3 bi-specific antibody, and an antibody to LAG3.

In 2016, we presented Phase 1 data from our PD-1 program, which helped us determine the 

therapeutic dose for our ongoing, potentially pivotal Phase 2 trial in cutaneous squamous cell 

carcinoma. This study is currently enrolling patients. In 2017, we plan to initiate a Phase 3 study 

in non-small cell lung cancer, as well as a potentially pivotal study in basal cell carcinoma.

We also presented interim data from our CD20xCD3 bi-specific program in 2016. The CD20xCD3 

antibody is currently in clinical trials both as a monotherapy and as a combination therapy with 

our PD-1 antibody.

We are also conducting studies of REGN3767, our antibody to LAG3, both as a monotherapy 

and as a combination therapy with our PD-1 antibody. A number of additional immuno-oncology 

antibodies are expected to enter the clinic in 2017 and 2018, and we continue to pursue business 

development opportunities with novel immuno-oncology approaches that have potential to be 

combined with antibodies.

RARE DISEASES

We are expanding our research into rare diseases, where serious unmet 
medical needs provide the opportunity to deliver on our mission of 
turning science into life-changing medicine. 

Our most clinically advanced rare disease antibody, evinacumab, an antibody to Angptl-3, is in clinical 

development for the treatment of homozygous familial hypercholesterolemia (HoFH), which is the most severe form 

of hypercholesterolemia. Patients with this disease are at a significantly higher risk of serious cardiac events, 

including heart attack and stroke. In the first half of 2016, we presented positive interim data from a Phase 2 

proof-of-concept study of evinacumab in patients with HoFH.

We also entered REGN2477, our antibody to Activin A, into clinical development for the treatment of fibroplasia 

ossificans progressiva (FOP). FOP is a progressive, severely disabling, and ultimately fatal disease in which muscles, 

ligaments, tendons, and other connective tissues are transformed into bone. We entered the drug into a Phase 1 

study in healthy volunteers in 2016, and expect to move into a Phase 2 trial in 2017. We also initiated a Phase 1 study 

of REGN2477 in combination with REGN1033, our antibody to GDF8, in 2016. REGN2477 has been granted orphan 

drug designation status by the FDA. 

In pre-clinical development we have a number of indications and programs identified, including transthyretin-related 

amyloidosis (TTR), juvenile X-Linked retinoschisis, and a C5 complement inhibitor for the treatment of paroxysmal 

nocturnal hemoglobinuria (PNH). We are working to advance these programs further in 2017.

Regeneron’s rapid response capabilities leverage our core 
VelociSuite® technologies to significantly compress the time 
required for discovery and pre-clinical validation of potential 
treatments for emerging infectious diseases. 

In 2016, work continued on our antibodies to the Ebola virus (REGN3470-3471-3479), where we began 

a Phase 1 study in healthy volunteers in the first half of 2016, and the antibody was granted orphan 

designation status by the FDA. This program is in development with the Biomedical Advanced 

Research and Development Authority (BARDA) of the U.S. Department of Health and Human Services.

In pre-clinical development, we also have antibodies to Middle Eastern respiratory virus (MERS) and 

the Zika virus.

The Regeneron Genetics Center (RGC) is one of the world’s largest 
genetic sequencing initiatives, providing important insights into target 
identification and clinical development. 

The Regeneron Genetics Center (RGC) is a leader in human genetics research. Our RGC scientists have 

sequenced more than 150,000 consented individuals, entered into more than 30 academic collaborations, and 

have continuously supported our clinical development efforts. We expect these efforts to help us discover new 

targets, indications and biomarkers that could better predict drug response, and help de-risk the process of 

bringing new medicines into the clinic. We ended 2016 with two simultaneous publications in Science, one of 

which provided the first overall description of the Geisinger-Regeneron Genetics Center (RGC) collaboration 

known as DiscovEHR, and the other demonstrated the underdiagnosis and undertreatment of familial 

hypercholesterolemia (FH) through pairing genetic variants causing FH with their de-identified medical histories. 

In March 2017, we announced a major new RGC initiative with UK Biobank and GSK, in which we will be 

sequencing 500,000 individuals in the UK Biobank’s health resource. We expect new and important 

publications and continued RGC progress in 2017.

REGENERON SCIENCE TALENT SEARCH

In 2016, Regeneron became the new sponsor of the Science Talent Search (STS), a program of 

the Society for Science & the Public, and our nation’s most prestigious science and math 

competition for high school seniors. This 76-year-old program was previously sponsored by 

Westinghouse and then by Intel. We made a 10-year, $100-million commitment, and nearly 

doubled the competition’s overall award distribution to $3.1 million annually. We are committed 

to expanding and diversifying the Science Technology Engineering and Math (STEM) talent pool, 

and have consequently earmarked $30 million for Society programs aiming to increase access 

to STEM education and resources for underrepresented populations.

In addition to the Regeneron STS, we focus our 
STEM education efforts across three areas of impact:

Regeneron is committed to supporting patients with serious diseases 
and ensuring that patients are able to access the medicines they need.

BRINGING ATTENTION TO A DEBILITATING DISEASE

The Understand AD national initiative aims to increase awareness and understanding of atopic dermatitis (AD), in 

partnership with the National Eczema Association (NEA) and the Dermatology Nurses’ Association (DNA). The 

most common form of eczema, AD is a chronic inflammatory disease with symptoms often appearing as a rash 

on the skin. The initiative offers a glimpse into the daily struggle of life with AD and connects people to 

helpful resources such as the NEA.

EDUCATION & AWARENESS FOR CHOLESTEROL MANAGEMENT

In 2016, Regeneron and Sanofi committed to support the American Heart Association’s cholesterol 

education program, Check.Change.Control.Cholesterol, which aims to drive millions of Americans to 

better cholesterol management. The three-year program will engage patients, caregivers and healthcare 

practitioners, and provide valuable educational resources to communities across the country. 

PARTNERING TO FIGHT A RARE DISEASE

Fibrodysplasia ossificans progressiva (FOP) is an exceedingly rare disease in which bone forms in the 

muscle and connective tissue. Over time, people living with FOP gradually lose the ability to move and even 

breathe as their rib cage loses flexibility. When Regeneron discovered that the protein Activin-A played a role 

in triggering FOP, we made it a priority to reach out to the small but strong FOP community to understand their 

daily struggles and treatment expectations. Since then, organizations such as the International Fibrodysplasia 

Ossificans Progressiva Association (IFOPA) and the National Organization for Rare Disorders (NORD) have been 

integral to informing the development of our investigational candidate REGN2477 and to helping us keep patient 
needs front and center in our efforts. We’ve also given back to the FOP community with grants and by sharing our 

genetically modified FOP mouse model with other scientists to advance basic and translational research. Through these 

mutually supportive relationships, we have come together with the FOP community to fight this devastating disease.
