RayzeBio
Defeating cancers with radiopharmaceutical medicines
Rayzebio is a dynamic biotechnology company headquartered in San Diego, CA.
Launched in late 2020 and recently acquired by Bristol Myers Squibb (BMS) as a wholly owned subsidiary, the company is focused on improving survival of people with cancer by harnessing the power of targeted radioisotopes.
Rayzebio will operate as a standalone entity within the BMS organization, maintaining its biotech culture with the opportunity to leverage the best-in-class oncology capabilities of BMS. Rayzebio is developing innovative drugs against targets of solid tumors.

Our approach
Purposeful discovery, development and manufacturing of innovative radiopharmaceuticals for solid tumors.
We believe we have established a leadership position in the emerging radiopharmaceutical therapeutics modality through a product-centric approach and have created a pipeline of multiple drug and development candidates in therapeutic areas with significant market opportunities.
Background
Despite recent therapeutic advances, there remains a high unmet need for new cancer treatments. External beam radiation, administered by high-energy rays, is a proven approach for many cancers. In contrast, radiopharmaceutical therapy (RPT) delivers radioisotopes to tumors intravenously.
We believe RPT is a promising new modality for treating solid tumors, offering both diagnostic and therapeutic benefits. The same drug conjugate can be used for diagnostic imaging and therapy by switching the radioisotope.
Both antibody drug conjugates (ADCs) and RPT consist of a binder, linker and payload targeting cancer cells. However, we believe RPT may offer advantages over ADCs in efficacy and safety.
