Focusing on providing full-process, integrated services for radiopharmaceuticals from pre-clinical to clinical translation

C Ray Therapeutics is dedicated to delivering end-to-end solutions for innovative radiopharmaceuticals to clients around the world. Our services span process development, quality research, preclinical evaluation, IND Enabling, clinical supply, and commercial scale cGMP production, all backed by a reliable, robust logistics network. As of 2024, we have raised over USD 187 million in total funding.

C Ray has 28,000 square-meter, state-of-the-art, world class R&D and cGMP manufacturing facilities with the highest Class A Radiation Safety License allowing commercial scale operational volume of over 30+ radioisotopes. GLP-like preclinical study center has both small and large lab animal use permit with animal feeding and administration lab, animal PET/CT for imaging, gama counter and pathology lab for biodistribution and dosimetry analysis.

C Ray has successfully delivered and continues to operate 60 CRDMO projects, including 44 preclinical and molecular imaging CRO projects and 17 CDMO projects. Among these, 3 have entered the IND and IND-enabling stages, 9 have advanced to investigator-initiated trials (IITs), and 5 have entered the clinical supply stage, with 2 of them successfully progressing to a Phase III clinical study. The company has achieved comprehensive coverage of all critical links across the entire radiopharmaceutical R&D and manufacturing chain.

As a dedicated CRDMO partner in radiopharmaceuticals, one of our core strengths is a stable, diversified supply of radionuclides. We are actively developing high-quality domestic sources while playing a leading role in integrating and fortifying the global supply chain—most notably securing access to challenging isotopes such as Ac-225. To date, we have supported the development of 16 Ac-225–labeled projects.

Committed to empowering the industry, C Ray Therapeutics is building an open, integrated “production–academia–research–application” platform. By pooling resources across the value chain and pioneering critical radiopharmaceutical technologies, we accelerate the clinical translation of integrated diagnostic & therapeutic solutions. Our goal is to drive innovation and industrial upgrading in the radiopharmaceutical sector, establishing ourselves as a global benchmark in the field.
