Regeneron Presentations at ASH Highlight Expanding Clinical Research in Blood Cancers and Disorders

New data for REGN5458 (BCMAxCD3 bispecific antibody) in patients with heavily pre-treated multiple myeloma to be highlighted in an oral presentation

First data evaluating a combination therapy approach with pozelimab (C5 antibody) and Alnylam's cemdisiran (siRNA C5 inhibitor) in healthy volunteers

Regeneron will host an investor webcast on Monday, December 13 to provide further updates across its hematology portfolio

TARRYTOWN, N.Y., Nov. 4, 2021 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that new and updated data from its diverse hematology program in blood cancers and disorders will be presented at the 2021 American Society of Hematology (ASH) Annual Meeting from December 11-14 in Atlanta, GA.

"Our hematology portfolio continues to expand with multiple trials now underway to investigate our bispecific antibodies, RNA-based therapies and gene editing, among other approaches," said L. Andres Sirulnik, M.D., Ph.D., Senior Vice President, Translational and Clinical Sciences, Hematology at Regeneron. "Our diverse pipeline includes investigational medicines across several blood cancers including multiple myeloma and lymphoma, in addition to blood disorders such as paroxysmal nocturnal hemoglobinuria, aplastic anemia, amyloidosis and thrombosis. We continue to make progress across our hematology portfolio with eight assets currently in the clinic."  

Regeneron data at ASH include an oral presentation with updated Phase 1 results from the completed dose escalation for REGN5458, an investigational BCMAxCD3 bispecific antibody, in patients with heavily pre-treated multiple myeloma. REGN5458 has the potential to advance treatment for patients with relapsed refractory disease, and the Phase 2 portion of this trial is currently enrolling with registrational intent. In addition, Regeneron and collaborator Alnylam will share the first data from healthy volunteers for a novel investigational combination of Regeneron's C5 antibody pozelimab and Alnylam's C5-inhibiting siRNA cemdisiran. The combination is planned to be evaluated in patients with the rare blood disorder, paroxysmal nocturnal hemoglobinuria (PNH), and other complement-driven disorders.

Additional presentations will include updated Phase 2 data investigating pozelimab monotherapy in patients with PNH, as well as analyses of real-world quality of life and treatment preferences among patients with diffuse large B-cell lymphoma to inform Regeneron's therapeutic development in this tumor type.

About Regeneron in Hematology
At Regeneron, we're translating more than three decades of biology expertise with our proprietary VelociSuite® technologies to develop potentially paradigm-changing 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 using CRISPR and gene-knockout technologies, as well as investigational RNA-approaches that are being investigated for their ability to deplete abnormal proteins or block disease-causing cellular signaling.
