Federal court jury found Amgen liable for violating antitrust and tort laws by using cross-therapeutic bundled rebates to prevent Praluent® (alirocumab) from competing in the market Jury awarded Regeneron $135.6 million dollars of compensatory damages and $271.2 million dollars in punitive damages TARRYTOWN, N.Y., May 15, 2025 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) applauds the jury verdict in the U.S. District Court for the District of Delaware that found that Amgen Inc. violated antitrust and tort laws by creating a bundling scheme that illegally leveraged its blockbuster anti-inflammatory drugs Enbrel® (etanercept) and Otezla® (apremilast) to convince pharmacy benefit managers (PBMs) to select Repatha® (evolocumab) as the exclusive PCSK9 category product over Praluent® (alirocumab). The jury found that Amgen violated the Clayton Act, the Sherman Act, the New York State Donnelly Act, the California Cartwright Act and Delaware tort law. Enbrel and Otezla are therapeutically different medicines that do not treat the heart conditions that Praluent or Repatha address. Amgen threatened to withhold rebates unless PBMs preferred Repatha and excluded Praluent. Amgen prevented Regeneron from competing on a level playing field and unfairly denied patients access to Praluent. This anticompetitive practice shut out an innovative therapy from the PCSK9 marketplace, not based on clinical merit or price. Because of Amgen’s size and unrelated product portfolio, their anticompetitive actions ultimately hurt competition and patients. The jury awarded Regeneron $135.6 million dollars of compensatory damages. The jury also awarded Regeneron $271.2 million dollars in punitive damages. Punitive damages may be awarded to punish a party for outrageous conduct and deter a party, and others like it, from engaging in similar conduct in the future. "Patients rely on the biotech industry to find solutions for their most urgent medical conditions. At Regeneron, we take this responsibility very seriously and are committed to delivering breakthrough therapies that improve patient lives. To achieve this, companies must be able to compete fairly based on the clinical and economic value of their products. Larger companies should not be allowed to use anticompetitive tactics to push competitors out of the market," said Leonard S. Schleifer, M.D., Ph.D., Board co-Chair, President and Chief Executive Officer of Regeneron. “Fair competition is critical as it expands patient access to life-changing therapies and drives innovation forward so we can continue to address the medical challenges of tomorrow.” “Since the FDA approved Praluent in 2015, Amgen has tried to remove and exclude Praluent from the market. After a failed patent litigation campaign, they pivoted toward an anticompetitive bundling scheme that created a dangerous precedent that virtually eliminated all competition,” said Joseph J. LaRosa, Executive Vice President, General Counsel and Secretary of Regeneron. “Today’s verdict validates Regeneron’s efforts to help protect patient access to our innovations and provides a clear sign that anticompetitive efforts will not remain unchecked.” Regeneron thanks the jury for their time and thoughtful consideration of the facts of this case. Regeneron’s lead counsel was Jonathan D. Polkes of White & Case LLP. About Praluent Praluent inhibits the binding of PCSK9 to the LDL receptor and thereby increases the number of available LDL receptors on the surface of liver cells to clear LDL, which lowers LDL-C levels in the blood. Praluent was developed by Regeneron and Sanofi under a global collaboration agreement and invented by Regeneron using the company's proprietary VelocImmune® technology that yields optimized fully-human monoclonal antibodies. In addition to the U.S., Praluent is approved in 60 countries, including the European Union, Japan, Canada, Switzerland and Brazil. About Regeneron’s VelocImmune Technology 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. Yancopouloswas 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 fully human monoclonal antibodies. This includes Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg). In addition, REGEN-COV®(casirivimab and imdevimab) had been authorized by the FDA during the COVID-19 pandemic until 2024.

18 presentations across five cancer types include new insights on the potential of checkpoint inhibitors and bispecific antibodies TARRYTOWN, N.Y. , May 01, 2025 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced new and updated data from its oncology and hematology portfolio will be shared at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place from May 30 to June 3 in Chicago, IL. Eighteen presentations will share the latest insights from ongoing research of approved and investigational treatment regimens across a range of difficult-to-treat cancers including non-melanoma and melanoma skin cancer, lung cancer, lymphoma and multiple myeloma. “Our broad oncology and hematology programs are uniquely designed to investigate regimens that could provide meaningful impact for people living with difficult-to-treat cancers across all stages of the treatment paradigm,” said George D. Yancopoulos , M.D., Ph.D., Board co-Chair, President and Chief Scientific Officer at Regeneron . “Our PD-1 inhibitor Libtayo is the standard of care in advanced cutaneous squamous cell carcinoma, and in clinical trials, our investigational BCMAxCD3 bispecific antibody linvoseltamab has demonstrated a compelling profile in relapsed or refractory multiple myeloma. At ASCO, our presentations showcase how we are seeking to further transform the treatment of these diseases with updates from two key programs – our Phase 3 trial exploring adjuvant Libtayo in high-risk cutaneous squamous cell carcinoma and early data from investigational combinations of linvoseltamab and different proteasome inhibitors in third-line or higher multiple myeloma.” Notable presentations at ASCO on Regeneron’s oncology pipeline include detailed efficacy and safety findings from the Phase 3 C-POST trial evaluating the adjuvant use of the PD-1 inhibitor Libtayo in post-surgical high-risk cutaneous squamous cell carcinoma (CSCC). The results will be presented in an oral session on Saturday, May 31 . In hematology, Regeneron will debut results from two cohorts of the LINKER-MM2 trial, which is exploring combinations of linvoseltamab, Regeneron’s investigational BCMAxCD3 bispecific antibody. These include combinations of linvoseltamab with carfilzomib or bortezomib in relapsed/refractory (R/R) multiple myeloma (MM) after at least two lines of therapy, which will be featured in two rapid oral presentations on Monday, June 2 . In addition, the results of a cooperative group study reporting on the primary analysis of a randomized Phase 2 trial of vidutolimod in combination with an anti-PD-1 versus anti-PD-1 as neoadjuvant therapy in stage 3 resectable melanoma will be presented in an oral session on Tuesday, June 3 . Vidutolimod is a toll like receptor 9 antagonist that was acquired by Regeneron in 2022. The full list of Regeneron presentations at ASCO includes: The potential uses of Libtayo in adjuvant CSCC, fianlimab, REGN7075, vidutolimod, and the combinations with linvoseltamab described above are investigational, and their safety and efficacy in these uses have not been fully evaluated by any regulatory authority. Fianlimab, REGN7075 and vidutolimod are not currently approved for use in any indication. Odronextamab is conditionally approved as Ordspono™ in the European Union for the treatment of R/R follicular lymphoma (FL) or diffuse large B-cell lymphoma (DLBCL) after two or more lines of systemic therapy, although its safety and efficacy have not been fully evaluated by any other regulatory authority. Linvoseltamab is conditionally approved as Lynozyfic™ in the European Union for the treatment of adult patients with R/R multiple myeloma who have received at least three prior therapies, including a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 monoclonal antibody, and have demonstrated disease progression on the last therapy, although its safety and efficacy have not been fully evaluated by any other regulatory authority. The U.S. Food and Drug Administration (FDA) accepted for review the Biologics License Applications for linvoseltamab and odronextamab with respective target action dates for FDA decisions of July 10, 2025 and July 30, 2025 .
