Regeneron Pharmaceuticals Stock Price, News & Analysis

Regeneron's Phase 2 trial data for odronextamab in relapsed/refractory follicular lymphoma revealed an impressive 82% response rate among patients, with 75% achieving complete responses. The median progression-free survival was reported at 20 months, while overall survival remains not reached. These outcomes are critical for anticipated regulatory submissions in 2023, including to the FDA. The study involved 121 patients, all of whom had undergone prior treatments. Safety evaluations noted adverse events mostly of grade 3 or higher, with cytokine release syndrome being common.

Regeneron Pharmaceuticals announced initial positive data from a pivotal Phase 2 trial for linvoseltamab (200 mg dose) at the ASH Annual Meeting. The trial included patients with high disease burden, showing a 64% response rate and 45% achieving very good partial responses. With a median follow-up of 3 months, results suggest ongoing efficacy and safety. Notably, 95% of patients reported adverse events, with 66% being severe. The complete dataset is under evaluation as the drug aims to address unmet needs in relapsed/refractory multiple myeloma.

Regeneron Pharmaceuticals (REGN) announced promising results from a Phase 1 and pivotal Phase 2 trial of odronextamab, showing a 49% objective response rate (ORR) in CAR-T naive patients, with 31% achieving a complete response (CR). In patients post-CAR-T therapy, an ORR of 48% and 32% CR were noted. Data will support regulatory submissions planned for 2023. The ongoing trials include ELM-1 and ELM-2, focusing on treating relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Adverse events were reported in 99% of patients, but no Grade 4 or 5 cytokine release syndrome cases were observed.

Regeneron Pharmaceuticals (REGN) announced key findings from its oncology pipeline at the ESMO IO Congress 2022 in Geneva. The results included initial data on the investigational combination of fianlimab and Libtayo in treating advanced non-small cell lung cancer (NSCLC). The Phase 1 trials indicated a 27% objective response rate in anti-PD-1/PD-L1-naïve patients and a 7% rate in experienced patients, demonstrating potential therapeutic benefits. Safety assessments showed adverse events but no treatment-related deaths. Additional presentations include analyses on melanoma and cervical cancer.

Regeneron Pharmaceuticals, Inc. (REGN) has announced that the FDA has accepted its supplemental Biologics License Application (sBLA) for Evkeeza® (evinacumab-dgnb) under Priority Review. This would establish Evkeeza as the first treatment for children aged 5 to 11 with homozygous familial hypercholesterolemia (HoFH). This condition affects 1,300 patients in the U.S. The trial indicated a significant average LDL-C reduction of 48% after 24 weeks of treatment. The FDA decision is expected by March 30, 2023.

Regeneron Pharmaceuticals announced the European Commission's approval of Libtayo (cemiplimab) for adult patients with recurrent or metastatic cervical cancer after platinum-based chemotherapy. This decision follows positive results from the Phase 3 EMPOWER-Cervical 1 trial, which demonstrated a 31% reduction in the risk of death compared to chemotherapy. Libtayo is now approved for four cancer types in the EU, marking a significant milestone in treatment options for advanced cervical cancer, which affects approximately 600,000 new cases globally each year.

Regeneron Pharmaceuticals and CytomX Therapeutics have entered a significant collaboration to develop next-generation bispecific immunotherapies. CytomX will receive an upfront payment of $30 million and could earn up to $2 billion in future milestones. The collaboration focuses on utilizing CytomX's Probody^® technology and Regeneron's Veloci-Bi^® platform to create therapies that activate specifically in tumor environments, potentially improving treatment efficacy and reducing side effects. The partnership aims to expand cancer treatment options significantly.

Regeneron Pharmaceuticals and Sanofi announced a positive opinion from the European Medicines Agency (EMA) recommending Dupixent (dupilumab) for treating adults with moderate-to-severe prurigo nodularis. If approved, Dupixent will be the first targeted medicine for this condition in the EU. Supported by two pivotal Phase 3 trials, the drug significantly improved itch, skin lesions, and health-related quality of life. Dupixent is already FDA-approved for the same indication in the U.S. The final decision from the European Commission is anticipated shortly.
