Yittrium-90(Y-90) Fibroblast Activation Protein Inhibitor (FAPI) Therapy in Patients With Non-Small Cell Lung Cancer (Phase II)

Description:

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide and accounts for approximately 80% of all lung cancer cases. Despite advances in chemotherapy, radiotherapy, and immunotherapy, the prognosis of patients with advanced-stage metastatic NSCLC remains poor, with limited therapeutic options after the development of treatment resistance. Fibroblast Activation Protein (FAP) is highly expressed in cancer-associated fibroblasts in a wide range of solid tumors and represents a promising target for tumor-specific theranostic approaches. Gallium-68-labeled FAPI (Ga-68 FAPI) PET/CT has recently demonstrated high sensitivity in imaging primary lung tumors and metastatic lesions. This Phase II study aims to evaluate the safety, feasibility, dosimetry, and therapeutic efficacy of Yttrium-90-labeled FAPI (Y-90 FAPI) radionuclide therapy in patients with chemotherapy-resistant metastatic NSCLC showing significant FAP expression on Ga-68 FAPI PET/CT imaging.
