Transcenta Announces the Publication of Preclinical Results of [177Lu]Lu-TST001 Radionuclide Antibody Conjugate as Potential Novel Treatment Option for Metastatic Gastric Cancer in the European Journal of Nuclear Medicine and Molecular Imaging
PRINCETON, N.J. and SUZHOU, China, Dec. 13, 2023 /PRNewswire/ -- Transcenta Holding Limited ("Transcenta") (HKEX: 06628), a clinical stage biopharmaceutical company with fully-integrated capabilities in discovery, research, development and manufacturing of antibody-based therapeutics, announces that the preclinical anti-tumor efficacy and safety results of [177Lu]Lu-TST001 have been published on European Journal of Nuclear Medicine and Molecular Imaging (EJNMMI). In this preclinical studies, [177Lu]Lu-TST001 demonstrated significant antitumor efficacy with acceptable toxicity. It exhibits strong potential for clinical translation, providing a new promising treatment option for CLDN18.2-overexpressing tumors, including gastric cancer.
This research was conducted in collaboration between Transcenta and the team of Professor Hua Zhu from Beijing Cancer HospitalCancer Hospital. In this study, a [177Lu]Lu-TST001 radionuclide antibody conjugate was developed that targets CLDN18.2 using a DOTA-TST001 as a precursor and is labeled with 177Lu, a therapeutic radionuclide. The clear molecular imaging, favorable biodistribution, and pharmacokinetics of [177Lu]Lu-TST001 were validated in a mouse xenograft GC model. Moreover, this study explored the short-term therapeutic efficacy of [177Lu]Lu-TST001 radioimmunotherapy (RIT) against CLDN18.2-positive tumors and determined the optimal therapeutic dose in a GC tumor model. Safety under the treatment dose of the probe was also examined. Significant therapeutic effects with acceptable short-term toxicity were achieved in the mouse model.
"Compared to localized gastric cancer, advanced metastatic gastric cancer often cannot be cured by chemotherapy or external radiation alone. In such cases, targeted RIT provides an opportunity to deliver radiation selectively to disease sites in patients with metastases, regardless of disease stage, offering a potential clinical treatment strategy for advanced tumor patients. We look forward to continuing our work with Prof Zhu and his team in an effort to bring [177Lu]Lu-TST001 radionuclide antibody conjugate to patients in the near future." said Dr. Xueming Qian, CEO of Transcenta.
