Linvoseltamab

Acceptance follows resolution of third-party fill/finish manufacturing issues FDA decision expected by July 10, 2025 TARRYTOWN, NY, USA I February 11, 2025 I Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the resubmission of the Biologics License Application (BLA) for linvoseltamab for the treatment of adult patients with relapsed/refractory (R/R) multiple myeloma (MM) who have received at least four prior lines of therapy or those who received three prior lines of therapy and are refractory to the last line of therapy. The target action date for the FDA decision is July 10, 2025. Acceptance of the BLA resubmission follows the resolution of third-party fill/finish manufacturing issues, which was the sole approvability issue identified by the FDA in the previous submission. The BLA is supported by data from the pivotal LINKER-MM1 trial investigating linvoseltamab in R/R MM, and linvoseltamab is also under review by the European Medicines Agency (EMA) for the same patient population. Linvoseltamab is investigational and has not been approved by any regulatory authority. About Multiple Myeloma As the second most common blood cancer, there are over 187,000 new cases of MM diagnosed globally every year, with more than 36,000 diagnosed and 12,000 deaths anticipated in the U.S. in 2025. In the U.S., there are approximately 8,000 people who have MM that has progressed after three lines of therapy, and 4,000 whose disease has progressed after four or more therapies. The disease is characterized by the proliferation of cancerous plasma cells (MM cells) that crowd out healthy blood cells in the bone marrow, infiltrate other tissues and cause potentially life-threatening organ injury. Despite treatment advances, MM is not curable and while current treatments are able to slow progression of the cancer, most patients will ultimately experience cancer progression and require additional therapies. About the Linvoseltamab Clinical Development Program Linvoseltamab is an investigational BCMAxCD3 bispecific antibody designed to bridge B-cell maturation antigen (BCMA) on MM cells with CD3-expressing T cells to facilitate T-cell activation and cancer-cell killing. The ongoing, open-label, multicenter Phase 1/2 dose-escalation and dose-expansion LINKER-MM1 trial is investigating linvoseltamab in 282 enrolled patients with relapsed/refractory MM. The Phase 1 dose-escalation portion of the trial – which is now complete – primarily assessed safety, tolerability and dose-limiting toxicities across nine dose levels of linvoseltamab and explored different administration regimens. The ongoing Phase 2 dose expansion portion is assessing the safety and anti-tumor activity of linvoseltamab, with the primary endpoint of objective response rate. Key secondary endpoints include duration of response, progression-free survival, rate of minimum residual disease negative status and overall survival. Eligibility in the Phase 2 portion requires patients to have received at least three prior lines of therapy or have triple-class refractory MM. Linvoseltamab is administered with an initial step-up dosing regimen followed by the full 200 mg dose administered weekly. At week 16, all patients transition to every two-week dosing. A response-adapted regimen further enables patients to shift to every four-week dosing if they achieve a very good partial response or better and have completed at least 24 weeks of therapy. The regimen requires a total of two 24-hour hospitalizations for safety monitoring. Linvoseltamab is being investigated in a broad clinical development program exploring its use as a monotherapy as well as in combination regimens across different lines of therapy in MM, including earlier lines of treatment, as well as plasma cell precursor disorders. They include evaluating linvoseltamab in a Phase 1b trial ( LINKER-MM2 ) in combination with other cancer treatments in R/R MM as well as a Phase 3 confirmatory trial ( LINKER-MM3 ) as a monotherapy in R/R MM.

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 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. About Regeneron Regeneron (NASDAQ: REGN) is a leading biotechnology company that invents, develops and commercializes life-transforming medicines for people with serious diseases. Founded and led by physician-scientists, our unique ability to repeatedly and consistently translate science into medicine has led to numerous approved treatments and product candidates in development, most 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, neurological diseases, hematologic conditions, infectious diseases, and rare diseases. Regeneron pushes the boundaries of scientific discovery and accelerates drug development using our proprietary technologies, such as VelociSuite , which produces optimized fully human antibodies and new classes of bispecific antibodies. We are shaping the next frontier of medicine with data-powered insights from the Regeneron Genetics Center ® and pioneering genetic medicine platforms, enabling us to identify innovative targets and complementary approaches to potentially treat or cure diseases.

再生元（Regeneron Pharmaceuticals）宣布，美国FDA已受理其为双特异性抗体疗法linvoseltamab所重新提交的生物制品许可申请（BLA），用于治疗已接受至少四线治疗，或已接受三线治疗且对最后一线治疗耐药的成年复发/难治性多发性骨髓瘤（MM）患者。FDA预计在2025年7月10日前对该申请做出审评决定。Linvoseltamab同时正在接受欧洲药品管理局（EMA）针对相同患者群体的审评。 Linvoseltamab是一种旨在将多发性骨髓瘤细胞上的B细胞成熟抗原（BCMA）与表达CD3的T细胞桥接，以促进T细胞活化和癌细胞杀伤的双特异性抗体。此次BLA重新提交的受理是在再生元解决第三方充填/封装制造问题之后进行的，该问题是FDA在之前该公司BLA提交中所唯一提出的问题。该BLA得到了关键性LINKER-MM1试验数据的支持，该试验评估了linvoseltamab在复发/难治性多发性骨髓瘤患者中的疗效。 2023年12月公布的试验结果显示，中位随访时间为11个月时，在1/2期临床试验（n=117）中接受剂量为200 mg的linvoseltamab治疗的患者中观察到客观缓解率为71%，46%达到完全缓解或更佳。 截至数据截止，所有接受200 mg治疗的患者均发生了不良事件（AE），其中85%的患者发生了≥3级不良事件（AE）。最常发生的AE为细胞因子释放综合征（CRS；46%）。在CRS病例中，大多数（35%）为1级，10%为2级，1例（1%）为3级CRS。 再生元的linvoseltamab全球项目负责人Karen Rodriguez-Lorenc博士此前在接受行业媒体Fierce Biotech采访时表示，在可比药物中，linvoseltamab所展现的CRS发生率处于“较低范围”。由于linvoseltamab是通过静脉注射，CRS病例发生在治疗后更早的时间点，因此允许更容易的监测和护理，此外，该药物的应答率在同类药物中处于“较高的范围”，因此linvoseltamab为潜在“best-in-class”靶向BCMA与CD3的双特异性抗体。 参考资料： [1] Linvoseltamab BLA Accepted for FDA Review for the Treatment of Relapsed/Refractory Multiple Myeloma.
