Regeneron Presents New Data at ASH from Advancing Hematology Pipeline across Multiple Blood Cancers and Disorders

"We've made significant strides toward developing a comprehensive hematology portfolio that has the potential to address diverse and difficult-to-treat blood cancers and blood disorders," said L. Andres Sirulnik, M.D., Ph.D., Senior Vice President, Translational and Clinical Sciences, Hematology at Regeneron. "Our ASH presentations not only showcase some of the many modalities we're exploring – which includes monoclonal antibodies, bispecific antibodies, gene modifying technologies, and siRNA inhibition – but also the depth of research we're conducting in support of our pipeline."

Notable Regeneron blood cancer presentations at ASH include the first interim data from the Phase 2 ELM-2 study of odronextamab (CD20xCD3) in relapsed/refractory (R/R) follicular lymphoma (FL) and R/R diffuse large B-cell lymphoma (DLBCL), which will be shared in two oral sessions. Updated Phase 1/2 data will also be presented for linvoseltamab (REGN5458; BCMAxCD3 bispecific antibody) in patients with heavily pre-treated multiple myeloma. Based on these findings, a recommended dose was selected for the Phase 2 portion of the linvoseltamab trial.

Additionally, first clinical data from two Phase 2 studies evaluating pozelimab (C5 antibody) in combination with Alnylam Pharmaceuticals, Inc.'s cemdisiran (siRNA C5 inhibitor) in patients with paroxysmal nocturnal hemoglobinuria (PNH), a rare blood disorder, will be shared.

About Regeneron in Hematology
At Regeneron, we're applying more than three decades of biology expertise with our proprietary VelociSuite® technologies to develop medicines for patients with diverse blood cancers and rare blood disorders.

Our blood cancer research is focused on bispecific antibodies that are being investigated both as monotherapies and in combination with each other and emerging therapeutic modalities. Together, they provide us with unique combinatorial flexibility to develop customized and potentially synergistic cancer treatments.

Our research and collaborations to develop potential treatments for rare blood disorders include explorations in antibody medicine, gene editing and gene-knockout technologies, and investigational RNA-approaches focused on depleting abnormal proteins or blocking disease-causing cellular signaling.

If you are interested in learning more about our clinical trials, please contact us ( clinicaltrials@regeneron.com or 844-734-6643) or visit our clinical trials website.

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. 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 approximately one in five of all original, FDA-approved or authorized fully human monoclonal antibodies. This includes REGEN-COV® (casirivimab and imdevimab), Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb) and Inmazeb™ (atoltivimab, maftivimab and odesivimab-ebgn).

About Regeneron
Regeneron is a leading biotechnology company that invents, develops and commercializes life-transforming medicines for people with serious diseases. Founded and led for nearly 35 years by physician-scientists, our unique ability to repeatedly and consistently translate science into medicine has led to nine FDA-approved treatments and numerous product candidates in development, almost all of which were homegrown in our laboratories. Our medicines and pipeline are designed to help patients with eye diseases, allergic and inflammatory diseases, cancer, cardiovascular and metabolic diseases, pain, hematologic conditions, infectious diseases and rare diseases.

Regeneron is accelerating and improving the traditional drug development process through our proprietary VelociSuite technologies, such as VelocImmune, which uses unique genetically humanized mice to produce optimized fully human antibodies and bispecific antibodies, and through ambitious research initiatives such as the Regeneron Genetics Center®, which is conducting one of the largest genetics sequencing efforts in the world.
