Bristol Myers Squibb and RayzeBio, Inc. announced a definitive merger agreement under which Bristol Myers Squibb will acquire RayzeBio for USD 62.50 per share in cash, for a total equity value of approximately 4.1 billion USD, or 3.6 billion USD net of estimated cash acquired. The transaction was unanimously approved by both the Bristol Myers Squibb and RayzeBio Boards of Directors.
RayzeBio is a clinical-stage radiopharmaceutical therapeutics (“RPT”) company with an innovation-leading position in actinium-based RPTs and a pipeline of potentially first-in-class and best-in-class drug development programs. Current pipeline programs are targeting the treatment of solid tumors, including gastroenteropancreatic neuroendocrine tumors (GEP-NETs), small cell lung cancer, hepatocellular carcinoma and other cancers. There remains a high, unmet need for more effective treatments in solid tumors, and RPTs enable a precision approach to patient treatment. RPTs bind to tumor cells and deliver targeted radiation to induce cancer cell death. Actinium-based RPTs offer potential advantages over currently available RPTs since the high potency and short firing range of the alpha-emitter create the possibility for stronger efficacy and more targeted delivery.
“This transaction enhances our increasingly diversified oncology portfolio by bringing a differentiated platform and pipeline, and further strengthens our growth opportunities in the back half of the decade and beyond,” said Christopher Boerner, Ph.D., Chief Executive Officer of Bristol Myers Squibb. “Radiopharmaceutical therapeutics are already transforming cancer care, and RayzeBio is at the forefront of pioneering the application of this novel modality. We look forward to supporting and accelerating RayzeBio’s preclinical and clinical programs and advancing its highly innovative radiopharmaceutical platform.”
“Acquiring RayzeBio’s differentiated actinium-based radiopharmaceutical platform will establish Bristol Myers Squibb’s presence in one of the most promising and fastest-growing new modalities for the treatment of patients with solid tumors – delivering radioactive payloads to cancer cells in a targeted manner,” said Samit Hirawat, M.D., Executive Vice President, Chief Medical Officer, Drug Development of Bristol Myers Squibb. “In addition, RayzeBio’s platform has the potential to be a significant IND engine, generating several therapeutic candidates in the future by leveraging our global drug development capabilities and infrastructure.”
Ken Song, M.D., President and CEO of RayzeBio, said, “Despite therapeutic advances in recent years, the need for more effective treatments in solid tumors persists, and radiopharmaceutical therapeutics are positioned to be an important next wave of innovation in oncology therapy. Bristol Myers Squibb’s well-established presence in oncology and deep expertise in developing, commercializing and manufacturing treatments on a global scale makes it the ideal partner for RayzeBio at this important moment in our evolution. I am excited to see what our team achieves as part of Bristol Myers Squibb.”
