Bristol Myers Squibb concludes acquisition of RayzeBio

“We are excited to complete this transaction, which adds radiopharmaceutical therapeutics (RPTs), one of the fastest-growing new modalities for treating patients with solid tumors,” said Chris Boerner, Ph.D., Chief Executive Officer, Bristol Myers Squibb. “By strengthening and further diversifying our oncology pipeline beyond I-O, we will unlock exciting opportunities that support BMS’s growth in the back half of the decade and beyond. RayzeBio is a pioneer in the application of this novel modality, and we look forward to working with their talented team to accelerate their preclinical and clinical programs for the benefit of patients around the world.”

This transaction brings a promising pipeline of RPTs to Bristol Myers Squibb, including RayzeBio’s lead program RYZ101 (²²⁵Ac-DOTATATE), which targets somatostatin receptor 2 (SSTR2), over-expressed in GEP-NETs and extensive stage small cell lung cancer (ES-SCLC). A Phase 3 clinical trial is currently enrolling patients to evaluate RYZ101 in patients with SSTR-positive GEP-NETs who have previously been treated with lutetium-177 based somatostatin therapies. RayzeBio previously reported the interim results of the Phase 1b portion of the ACTION-1 clinical trial, suggesting encouraging efficacy and tolerability. A Phase 1b clinical trial is also currently enrolling patients to evaluate RYZ101 as a first-line treatment of ES-SCLC in combination with standard-of-care therapy. The platform has the potential to be a significant IND engine to generate a number of candidates and comes with a state-of-the-art RPT manufacturing facility, which is expected to begin operating in the first half of 2024.
