Oral presentation shares head-to-head results for investigational combination pozelimab plus cemdisiran vs. ravulizumab in paroxysmal nocturnal hemoglobinuria

Initial results for odronextamab in first-line follicular lymphoma showcase compelling monotherapy potential and progress in the confirmatory trial

Additional oral presentations explore odronextamab in areas of high unmet need, including the primary analysis in diffuse large B-cell lymphoma progressing after CAR-T therapy and first results in relapsed/refractory marginal zone lymphoma

TARRYTOWN, N.Y., Nov. 13, 2024 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced new and updated data from its hematology pipeline will be shared across 23 abstracts at the American Society of Hematology (ASH) 2024 Annual Meeting, taking place from December 7-10 in San Diego, CA. The latest research advances demonstrate the potential of Regeneron's diverse pipeline, which aims to address unmet needs in ten types of blood cancers and disorders. These innovative and differentiated approaches include CD3 bispecific antibodies, costimulatory bispecific antibodies, and a pioneering combination of a monoclonal antibody and small interfering RNA (siRNA).

"Our presentations at ASH demonstrate the progress we are making toward transforming care for a range of blood cancers and disorders where advancements are desperately needed," said L. Andres Sirulnik, M.D., Ph.D., Senior Vice President and Hematology Clinical Development Unit Head at Regeneron. "These include new head-to-head data exploring a novel combination that aims to maximize disease control in paroxysmal nocturnal hemoglobinuria compared to a standard-of-care treatment, as well as initial results from our confirmatory odronextamab trial in first-line follicular lymphoma. Together, our presentations underscore our commitment to work towards translating scientific breakthroughs to differentiated medicines for hematology patients."

At ASH, abstracts in blood disorders include an oral presentation from an exploratory cohort of a Phase 3 trial investigating a novel combination of pozelimab with cemdisiran compared to ravulizumab in patients with paroxysmal nocturnal hemoglobinuria (PNH) who were naïve to complement inhibition at baseline. Notably, the presentation will detail interim results from patients who were initially randomized to ravulizumab but crossed over to the combination in an open label extension portion of the trial.

Progress on the odronextamab development program will be featured in twelve abstracts. Among them are initial results in patients with previously untreated follicular lymphoma (FL) from Part 1 of the Phase 3 OLYMPIA-1 confirmatory trial, which consists of a non-randomized safety run-in (Part 1) followed by a randomized efficacy portion (Part 2) comparing odronextamab monotherapy to rituximab plus standard-of-care chemotherapies. Two oral presentations on the ELM-1 and pivotal ELM-2 trials will feature new analyses in settings with significant unmet needs: one in patients with diffuse large B-cell lymphoma (DLBCL) who progressed after CAR-T therapy and the other in relapsed/refractory (R/R) marginal zone lymphoma (MZL).

Other notable abstracts include the latest linvoseltamab efficacy and safety results from the pivotal LINKER-MM1 study in R/R multiple myeloma (MM), preclinical data evaluating a CD38xCD28 costimulatory bispecific antibody in combination with linvoseltamab, and preclinical data on TMPRSS6 inhibition in beta-thalassemia.

The full list of Regeneron presentations at ASH includes:

*Agreement with Alnylam Pharmaceuticals, Inc.

Linvoseltamab as well as the combination of pozelimab and cemdisiran are investigational, and the potential uses of odronextamab in R/R MZL and rare subtypes of R/R aggressive B-cell non-Hodgkin lymphoma are also investigational and have not been approved by any regulatory authority. Odronextamab is approved in the European Union as Ordspono to treat R/R FL or DLBCL after two or more lines of systemic therapy, but the safety and efficacy of odronextamab have not been fully evaluated by any other regulatory authority.

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 various combinations 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.

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 a substantial proportion of all original, FDA-approved or authorized fully human monoclonal antibodies. This includes REGEN-COV (casirivimab and imdevimab), Dupixent (dupilumab), Libtayo, Praluent (alirocumab), Kevzara (sarilumab), Evkeeza (evinacumab-dgnb), Inmazeb (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz (pozelimab-bbfg).
