(NASDAQ: REGN) today announced the presentation of new and updated data on multiple combination therapies from its oncology pipeline at the European Society for Medical Oncology Immuno-Oncology (ESMO IO) Congress 2023 from December 6 to 8 in Geneva, Switzerland. Highlights include first Phase 1 dose-escalation data for the investigational costimulatory bispecific antibody REGN5668 (MUC16xCD28) in combination with PD-1 inhibitor Libtayo® (cemiplimab) showing encouraging initial activity in patients with recurrent ovarian cancer. Additionally, a late-breaking oral presentation will detail the first results from a Phase 2 trial investigating neoadjuvant Libtayo in combination with low-dose stereotactic body radiotherapy (SBRT) in patients with early-stage hepatocellular carcinoma (HCC). “Our ESMO IO presentations highlight the continued progress of Regeneron’s oncology pipeline, which was strategically curated to have the potential to offer novel and differentiated combinations targeting several types of difficult-to-treat cancers. We look forward to sharing first clinical data from our costimulatory bispecific program in patients with recurrent ovarian cancer, which is investigating a MUC16xCD28 bispecific antibody in combination with our PD-1 inhibitor Libtayo,” said Israel Lowy, Senior Vice President, Translational and Clinical Oncology at Regeneron. “This is our second costimulatory bispecific program to report clinical data, with a total of four such agents currently in the clinic, and adds to the evidence showing that our novel CD28 costimulatory bispecifics can potentially enhance the anti-tumor activity of anti-PD-1 therapies in a synergistic fashion. Studies are also underway exploring the combination of CD28 costimulatory bispecifics with CD3 bispecifics, including REGN5668 with ubamatamab, our MUC16xCD3 bispecific.” Per initial results to be s...
