On December 10, Tongrui Biopharmaceuticals (Chengdu) Co., Ltd. (hereinafter referred to as “Tongrui Bio”) successfully obtained the Class A Radiation Safety License once again. This achievement marks another breakthrough following its initial acquisition of the license in September 2023, further demonstrating the professionalism and efficiency of the Tongrui team.
This marks Tongrui Bio’s further expansion in the field of radionuclide production and handling. This significant milestone also demonstrates recognition by relevant authorities of Tongrui Bio’s expertise in multiple specialized areas, including nuclear physics, radiochemistry, and radiation safety.
The adjustment and upgrade of the radiation safety license are mainly reflected in three aspects:
01
R&D Laboratory Upgrade | Class A Workplace

02
New Production Line in Pilot-Scale Production Area | Class A Workplace


03
New Positron Emission Tomography (PET) Radiopharmaceutical Production Line

Conclusion
Tongrui Biopharma handles more than 30 diagnostic and therapeutic radionuclides. Leveraging state-of-the-art radiopharmaceutical R&D and manufacturing facilities, as well as a high-caliber multidisciplinary team with core competencies in radiochemistry, molecular imaging, dosimetry, and translational medicine, Tongrui Biopharma’s R&D platform covers the entire drug development process, including radiopharmaceutical process development, quality research, quality control, pharmacodynamics, pharmacokinetics, and safety evaluation. On one hand, Tongrui Biopharma provides one-stop CRDMO services to radiopharmaceutical companies, ranging from CRO services for early-stage discovery and PCC validation to IND filing, clinical supply, and commercial manufacturing, including downstream logistics and distribution. Tongrui Biopharma has established stable channels for radionuclide supply and product logistics, ensuring efficient, stable, and comprehensive operation of its supply chain system, with coverage across the Asia-Pacific region. On the other hand, Tongrui Biopharma offers molecular imaging CRO and companion diagnostic development services to conventional pharmaceutical companies, as well as validation services to assess the druggability of new drugs targeting innovative indications. Since launching its CRDMO services,Tongrui Biotech has cumulatively served 4 CDMO projects, 20+ theranostics and molecular imaging CRO projects, as well as multiple ongoing177Lu、225Ac-labeled radiopharmaceuticals and RDC drug development projects.
Looking ahead, Tongrui Biopharma will leverage its radiopharmaceutical R&D and manufacturing base compliant with global cGMP standards, along with state-of-the-art radioactive R&D and production facilities, to build an open “industry-academia-research-application” CRDMO service platform, continuously empowering and accelerating the new drug development process.
