RayzeBio
Defeating cancers with radiopharmaceutical medicines
RayzeBio, a Bristol Myers Squibb Company, is a dynamic clinical-stage radiopharmaceutical therapeutics (RPT) company headquartered in San Diego, CA. The company – which operates as a standalone entity within BMS – has an industry-leading position in actinium-based RPTs, a pipeline of potentially first-in-class and best-in-class drug programs, and a state-of-the-art manufacturing facility.
Despite therapeutic advances made in the last decade, there remains a high unmet need for new cancer treatments. RayzeBio is focused on improving the survival of people with cancer by harnessing the power of targeted radioisotopes. The company is developing innovative drugs against targets of solid tumors, potentially offering benefits for patients in safety and efficacy.
RayzeBio has two locations:
- An R&D Center of Excellence in San Diego, CA, equipped with full in vitro biological capabilities and internal small molecule and peptide chemistry
- A state-of-the-art research and manufacturing facility in Indianapolis, IN, to allow for end-to-end drug development and commercial production.
With the backing and support of Bristol Myers Squibb, RayzeBio has a vision to become the world’s leader in radiopharmaceutical therapeutics, one of the most promising new modalities for the treatment of cancer.

Science
We are focused on purposeful discovery, development and manufacturing of innovative radiopharmaceutical therapeutics (RPTs) for solid tumors.
RPT is positioned to a core modality in cancer treatment – with the potential to be combined across other modalities. This treatment has the advantage of being both diagnostic and therapeutic, and may offer advantages in efficacy and safety. RayzeBio is at the forefront of pioneering the application of RPTs using an alpha-emitting isotope, Ac225.
We expect to generate several therapeutic candidates by leveraging critical capabilities, infrastructure, and dedicated manufacturing facility.
Pipeline
With the backing of BMS, and the drive of a biotechnology company, we are focused on efficiently delivering for patients. We are focused on targets with a high expression in significant tumors and have created a pipeline of multiple drug and development candidates in therapeutic areas with significant market opportunities.
RayzeBio programs leverage Ac225, an alpha emitter. Alpha emitters are the next-generation of therapeutic radionuclides. Due to higher potency, Ac225 may enhance RPT results, enabling efficacy in tumors with lower target expression and overcoming resistance to beta radiation. Alpha particles deliver up to 400 times higher energy compared to beta particles, leading to double-stranded DNA breaks which are lethal to cancer cells.
