(NASDAQ: REGN) today announced financial results for the third quarter of 2024 and provided a business update. "Regeneron had a strong third quarter marked by 11% revenue growth. We continued to deepen the impact of our commercialized medicines this quarter, with ongoing leadership for our retinal franchise, expanded global reach of Libtayo, and notable growth from Dupixent," said Leonard S. Schleifer, M.D., Ph.D., Board co-Chair, President and Chief Executive Officer of Regeneron. "Over one million patients around the globe are currently being treated with Dupixent, with more to come following the approvals for COPD in the U.S., Europe and China. Our remarkably diverse clinical portfolio now includes approximately 40 product candidates and many pivotal studies underway. We continue to invest in the world-class research and development engine that drives our scientific and clinical productivity, with data expected over the next twelve months in diseases as varied as non-small cell lung cancer, thrombosis, retinal vein occlusion, severe allergy, COPD, melanoma, and obesity."

"We remain focused on translating cutting-edge science into differentiated medicines that have the greatest potential to serve patients, while deploying capital with the goal of maximizing shareholder returns, primarily through investing in innovation coupled with opportunistic share repurchases." Business Highlights Key Pipeline ProgressRegeneron has approximately 40 product candidates in clinical development, including a number of marketed products for which it is investigating additional indications. Updates from the clinical pipeline include: EYLEA HD (aflibercept) 8 mg The Company announced positive three-year (156-week) data from an extension study of the Phase 3 PHOTON trial in patients with diabetic macular edema (DME). At three years, the longer-term data showed the vast majority of EYLEA HD patients who entered the extension study sustained the visual gains and anatomic improvements achieved by the end of the second year. Of the EYLEA HD patients who completed the full 156 weeks of treatment, 48% were assigned a dosing interval of ≥20 weeks at the end of the third year. The results were presented at the American Academy of Ophthalmology (AAO) Annual Meeting. Dupixent (dupilumab) In September 2024, the U.S. Food and Drug Administration (FDA) approved Dupixent as an add-on maintenance treatment for adults with inadequately controlled COPD and an eosinophilic phenotype. With this approval, Dupixent is the first biologic medicine approved in the United States, European Union (EU), and China to treat these patients.In September 2024, the FDA approved Dupixent as an add-on maintenance treatment for adolescents aged 12 to 17 years with inadequately controlled chronic rhinosinusitis with nasal polyposis (CRSwNP).The European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending expanded approval of Dupixent in the EU to treat children aged 1 to 11 years with eosinophilic esophagitis (EoE). The European Commission (EC) is expected to announce a final decision in the coming months.The Company and Sanofi announced that a confirmatory Phase 3 trial met the primary and key secondary endpoints for the investigational treatment of patients with uncontrolled, biologic-naïve CSU receiving background therapy with antihistamines, showing treatment with Dupixent resulted in a nearly 50% reduction in itch and urticaria activity scores from baseline. This positive trial confirms results from the first Phase 3 trial of Dupixent in this setting and these data supported the recent resubmission of a supplemental Biologics License Application (sBLA) to the FDA.The Company and Sanofi announced that a Phase 3 trial in bullous pemphigoid met the primary and all key secondary endpoints evaluating the investigational use in adults with moderate-to-severe disease. In the trial, five times more Dupixent patients achieved sustained disease remission compared to those on placebo. This trial will support global regulatory submissions, including the anticipated fourth quarter 2024 submission in the United States. Oncology Programs In August 2024, the EC approved Ordspono™ (odronextamab) to treat adult patients with relapsed or refractory (R/R) follicular lymphoma (FL) or R/R diffuse large B-cell lymphoma (DLBCL), after two or more lines of systemic therapy.The Company announced five-year results from the final pre-specified overall survival (OS) analysis of a Phase 3 trial, which evaluated Libtayo (cemiplimab) monotherapy versus chemotherapy as a first-line treatment for certain adults with advanced non-small cell lung cancer (NSCLC) with ≥50% PD-L1 expression. The results were presented at the IASLC 2024 World Conference on Lung Cancer.The Company submitted a regulatory application in Japan for Libtayo for first-line advanced NSCLC (monotherapy and chemotherapy combination).A Phase 2 study for Libtayo in neoadjuvant NSCLC was initiated.The Company presented new, two-year results at the European Society for Medical Oncology (ESMO) Annual Meeting, evaluating the investigational combination of fianlimab, an antibody to LAG-3, and Libtayo in adults with advanced melanoma across three independent expansion cohorts of a first-in-human, multi-cohort trial. These longer-term results show high clinical activity, including deepening responses, per a blinded independent central review.In August 2024, the FDA issued a Complete Response Letter (CRL) for the BLA for linvoseltamab, a bispecific antibody targeting BCMA and CD3, in R/R multiple myeloma that has progressed after at least three prior therapies. The sole approvability issue identified is related to findings from a pre-approval inspection at a third-party fill/finish manufacturer. Resolution of this issue will be required for both FDA and EC regulatory approvals. Other Programs A Phase 3 study was initiated for pozelimab, an antibody to C5, in combination with cemdisiran, an siRNA therapy, in geographic atrophy.A Phase 2 study for REGN7999, an antibody to TMPRSS6, for the treatment of iron overload in patients with beta-thalassemia was initiated.

EYLEA HD was approved by the FDA in August 2023 and net product sales in the third quarter of 2024 were driven by the transition of patients from other anti-VEGF products, including EYLEA, as well as new patients naïve to anti-VEGF therapy. Net product sales of EYLEA in the third quarter of 2024 were adversely impacted by a lower net selling price compared to the third quarter of 2023. In addition, third quarter 2024 total EYLEA HD and EYLEA net product sales were favorably impacted by approximately $40 million as a result of higher wholesaler inventory levels for EYLEA HD at the end of the third quarter of 2024 compared to the end of the second quarter of 2024, partially offset by lower wholesaler inventory levels for EYLEA. Sanofi collaboration revenue increased in the third quarter of 2024, compared to the third quarter of 2023, due to an increase in the Company's share of profits from commercialization of antibodies, which were $1.09 billion in the third quarter of 2024, compared to $863 million in the third quarter of 2023. The change in the Company's share of profits from commercialization of antibodies was driven by higher profits associated with an increase in Dupixent sales. Sanofi collaboration revenue in the third quarter of 2023 was positively impacted by the recognition of the final $50 million sales-based milestone.

Acquired IPR&D expense in the third quarter of 2023 related to a $100 million development milestone in connection with the Company's collaboration with Alnylam Pharmaceuticals, Inc.GAAP and non-GAAP SG&A expenses increased in the third quarter of 2024, compared to the third quarter of 2023, due to higher commercialization-related expenses to support the Company's launch of EYLEA HD and higher headcount and headcount-related costs partly related to the Company's international commercial expansion.GAAP and non-GAAP COGS increased in the third quarter of 2024, compared to the third quarter of 2023, primarily due to higher start-up costs for the Company's Rensselaer, New York fill/finish facility. Other Financial Information GAAP other income (expense) included the recognition of net unrealized gains on equity securities of $135 million in the third quarter of 2024, compared to $100 million of net unrealized losses in the third quarter of 2023. GAAP and Non-GAAP other income (expense) also included interest income of $187 million in the third quarter of 2024, compared to $134 million in the third quarter of 2023. In the third quarter of 2024, the Company's GAAP effective tax rate (ETR) was 10.2%, compared to 9.3% in the third quarter of 2023. The GAAP ETR increased in the third quarter of 2024, compared to the third quarter of 2023, due to a lower benefit from income earned in foreign jurisdictions with tax rates lower than the U.S. federal statutory rate. In the third quarter of 2024, the non-GAAP ETR was 10.7%, compared to 11.9% in the third quarter of 2023. GAAP net income per diluted share was $11.54 in the third quarter of 2024, compared to $8.89 in the third quarter of 2023. Non-GAAP net income per diluted share was $12.46 in the third quarter of 2024, compared to $11.59 in the third quarter of 2023. A reconciliation of the Company's GAAP to non-GAAP results is included in Table 3 of this press release. During the third quarter of 2024, the Company repurchased shares of its common stock and recorded the cost of the shares, or $738 million, as Treasury Stock. As of September 30, 2024, $2.9 billion remained available for share repurchases under the Company's share repurchase program. 2024 Financial Guidance(c) The Company's full year 2024 financial guidance consists of the following components: 2024 Guidance Prior UpdatedGAAP R&D $5.020–$5.170 billion $5.055–$5.145 billionNon-GAAP R&D(a) $4.500–$4.600 billion $4.525–$4.575 billionGAAP SG&A $2.920–$3.060 billion $2.930–$3.020 billionNon-GAAP SG&A(a) $2.550–$2.650 billion $2.550–$2.600 billionGAAP gross margin on net product sales(d) Approximately 86% UnchangedNon-GAAP gross margin on net product sales(a)(d) Approximately 89% UnchangedCOCM(e)* $850–$910 million $860–$900 millionCapital expenditures* $750–$820 million $700–$740 millionGAAP effective tax rate 8%–9% UnchangedNon-GAAP effective tax rate(a) 10%–11% Unchanged * GAAP and non-GAAP amounts are equivalent as no non-GAAP adjustments have been or are expected to be recorded.

These non-GAAP financial measures are computed by excluding certain non-cash and/or other items from the related GAAP financial measure. The Company also includes a non-GAAP adjustment for the estimated income tax effect of reconciling items. A reconciliation of the Company's GAAP to non-GAAP results is included in Table 3 of this press release.The Company makes such adjustments for items the Company does not view as useful in evaluating its operating performance. For example, adjustments may be made for items that fluctuate from period to period based on factors that are not within the Company's control (such as the Company's stock price on the dates share-based grants are issued or changes in the fair value of the Company's investments in equity securities) or items that are not associated with normal, recurring operations (such as acquisition and integration costs). Management uses these non-GAAP measures for planning, budgeting, forecasting, assessing historical performance, and making financial and operational decisions, and also provides forecasts to investors on this basis. With respect to free cash flows, the Company believes that this non-GAAP measure provides a further measure of the Company's ability to generate cash flows from its operations. Additionally, such non-GAAP measures provide investors with an enhanced understanding of the financial performance of the Company's core business operations. However, there are limitations in the use of these and other non-GAAP financial measures as they exclude certain expenses that are recurring in nature. Furthermore, the Company's non-GAAP financial measures may not be comparable with non-GAAP information provided by other companies. Any non-GAAP financial measure presented by the Company should be considered supplemental to, and not a substitute for, measures of financial performance prepared in accordance with GAAP. (b)The casirivimab and imdevimab antibody cocktail for COVID-19 is known as REGEN-COV® in the United States and Ronapreve in other countries. Roche records net product sales of Ronapreve outside the United States. (c)The Company's 2024 financial guidance does not assume the completion of any business development transactions not completed as of the date of this press release. (d)Gross margin on net product sales represents gross profit expressed as a percentage of total net product sales recorded by the Company. Gross profit is calculated as net product sales less cost of goods sold. (e)Corresponding reimbursements from collaborators and others for manufacturing of commercial supplies is recorded within revenues.

Dupixent significantly reduced itch and hive activity from baseline; 41% of patients achieved well-controlled disease status Confirmatory data to support U.S. regulatory resubmission by year-end; if approved, Dupixent would be the first new targeted treatment for people living with chronic spontaneous urticaria in more than 10 years More than 300,000 people in the U.S. suffer from chronic spontaneous urticaria that is inadequately controlled by antihistamines Oct. 24, 2024 -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi will present positive data from the Phase 3 LIBERTY-CUPID Study C evaluating the investigational use of Dupixent® (dupilumab) in biologic-naïve patients with uncontrolled chronic spontaneous urticaria (CSU) who receive background therapy with antihistamines. Results showed treatment with Dupixent significantly reduced itch and urticaria activity (itch and hive) scores from baseline, and a higher proportion of patients achieved well-controlled disease status compared to placebo. The data are being shared in a late-breaking oral presentation at the American College of Allergy, Asthma & Immunology (ACAAI) 2024 Annual Scientific Meeting in Boston, Massachusetts. “Chronic spontaneous urticaria is an inflammatory skin condition that affects patients with unpredictable episodes of intense itching and hives, often severely impacting their daily lives," said Thomas B. Casale, M.D., Professor, Internal Medicine, Morsani College of Medicine at the University of South Florida, USA. "These data confirm results seen in the previous Study A and reinforce the potential of Dupixent to significantly alleviate symptoms for patients, helping them to better control this challenging disease.” Study C enrolled 151 children and adults who were randomized to receive Dupixent (n=74) or placebo (n=77) added to standard-of-care histamine-1(H1) antihistamines. At 24 weeks, Dupixent demonstrated significant improvements compared to placebo on: Itch severity score (8.64- vs. 6.10-point reduction from baseline; p=0.02) Urticaria (itch and hive) activity score (15.86- vs. 11.21-point reduction from baseline; p=0.02). Well-controlled disease status (urticaria activity score ≤6; 41% vs. 23%; p=0.005) Complete response (urticaria activity score=0; 30% vs. 18%; p=0.02) The safety results in Study C were generally consistent with the known safety profile of Dupixent in its approved dermatological indications. Overall rates of treatment emergent adverse events (AEs) were 53% for both Dupixent and placebo. AEs more commonly observed with Dupixent (≥5%) compared to placebo included injection site reactions (12% vs. 4%), accidental overdose (7% vs. 3%) and COVID-19 infection (8% vs. 5%). Dupixent has been approved for CSU in Japan and the United Arab Emirates (UAE) and is also under regulatory review in the European Union based on earlier trial readouts. Outside of Japan and the UAE, the safety and efficacy of Dupixent for CSU has not been fully evaluated by any regulatory authority. CSU is a chronic inflammatory skin disease driven in part by type 2 inflammation, which causes sudden and debilitating hives and persistent itch. CSU is typically treated with H1 antihistamines, medicines that target H1 receptors on cells to control symptoms of urticaria. However, the disease remains uncontrolled despite antihistamine treatment in many patients, some of whom are left with limited alternative treatment options. These individuals continue to experience symptoms that can be debilitating and significantly impact their quality of life. More than 300,000 people in the U.S. suffer from CSU that is inadequately controlled by antihistamines. The LIBERTY-CUPID Phase 3 program evaluating Dupixent for CSU consists of Study A, Study B and Study C. Study C was a randomized, double-blind, placebo-controlled clinical trial that evaluated the efficacy and safety of Dupixent as an add-on to standard-of-care antihistamines compared to antihistamines alone in 151 patients aged six years and older with CSU who remained symptomatic despite antihistamine use and were not previously treated with omalizumab (i.e., biologic-naïve). The primary endpoint assessed the change from baseline in itch at 24 weeks (measured by the weekly itch severity score [ISS7], 0-21 scale). Secondary endpoints at 24 weeks, measured by the weekly urticaria activity score (UAS7), included the change from baseline in itch and hives (UAS7, 0-42 scale), proportion of patients achieving well-controlled disease status (UAS7 ≤6), and complete response (UAS7=0). Dupixent, which was invented using Regeneron’s proprietary VelocImmune® technology, is a fully human monoclonal antibody that inhibits the signaling of the IL-4 and IL-13 pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in Phase 3 trials, establishing that IL-4 and IL-13 are two of the key and central drivers of type 2 inflammation that play a major role in multiple related and often co-morbid diseases. Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, prurigo nodularis, CSU, and chronic obstructive pulmonary disease in different age populations. More than 1,000,000 patients are being treated with Dupixent globally. Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create a substantial proportion of all original, FDA-approved or authorized fully human monoclonal antibodies. This includes REGEN-COV® (casirivimab and imdevimab), Dupixent, Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz™ (pozelimab-bbfg). Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical trials involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation. In addition to the currently approved indications, Regeneron and Sanofi are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in Phase 3 trials, including chronic pruritus of unknown origin and bullous pemphigoid. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.
