PD-L1 Specific [68Ga]Ga-THP-PDL1-3 Probe for PET Imaging in Solid Tumors

Summary

To utilize the \[68Ga\]Ga-THP-PDL1-3 molecular probe to non-invasively detect PD-L1 expression in primary and metastatic lesions of patients with solid tumors. Furthermore, to assess the heterogeneity of PD-L1 expression within the same lesion and across different lesions, and to observe changes in PD-L1 expression during the course of treatment. This approach aims to facilitate patient screening, therapeutic monitoring, and early warning of drug resistance and/or recurrence or metastasis in the treatment of solid tumors with high PD-L1 expression, ultimately enabling personalized targeted therapy in oncology.
