About this study

Official title: A Novel Therapeutic Target in Non-Small Cell Lung Cancer: Evaluation of the Efficacy of Yttrium-90 (Y-90) Fibroblast Activation Protein Inhibitor (FAPI) - A Phase II Study

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.

Read the detailed description

Lung cancer remains the most common cause of cancer-related death globally, and non-small cell lung cancer (NSCLC) constitutes approximately 80% of all lung cancer cases. Patients with advanced or metastatic NSCLC have a particularly poor prognosis, with a 5-year survival rate of less than 10%, even among those who initially respond to systemic therapies. In patients with widespread metastatic disease, the addition of immune checkpoint inhibitors to chemotherapy and external beam radiotherapy provides only a limited survival benefit.

Fibroblast Activation Protein (FAP) is a cell surface protein expressed in up to 90% of cancer-associated fibroblasts and has emerged as a novel tumor-specific therapeutic target. Recent clinical studies have demonstrated that Ga-68 FAPI PET/CT is highly effective in visualizing primary NSCLC lesions as well as pleural, nodal, adrenal, and brain metastases.

Yttrium-90 (Y-90) is a beta-emitting radionuclide with a physical half-life of approximately 64 hours and favorable radiation characteristics for radionuclide therapy. Based on the high tumor uptake observed on Ga-68 FAPI PET/CT imaging, Y-90 FAPI is expected to selectively target FAP-expressing tumor lesions while minimizing radiation exposure to healthy tissues.

Although large-scale clinical trials investigating Y-90 FAPI therapy are currently lacking, limited case-based applications have been reported in other solid tumors, including breast cancer and osteosarcoma. This Phase II study aims to address this gap by systematically evaluating Y-90 FAPI therapy in patients with chemotherapy-resistant metastatic NSCLC.

Eligible patients will undergo Ga-68 FAPI PET/CT imaging prior to treatment. Patients demonstrating significant FAP expression in primary and metastatic tumor lesions will be selected for Y-90 FAPI radionuclide therapy. The radiolabeling of Y-90 FAPI will be performed under appropriate quality control conditions, including assessment of radiochemical purity and stability, prior to clinical administration.

Y-90 FAPI will be administered intravenously to selected patients. Patients will be followed with clinical assessments, laboratory tests, and radiological imaging. Post-therapy imaging and dosimetric evaluations will be performed using Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) to assess organ and tumor radiation doses. Safety and tolerability will be monitored throughout the study, and adverse events will be recorded and graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.

This study aims to establish a novel nuclear medicine-based theranostic treatment approach for patients with metastatic NSCLC who have exhausted standard therapeutic options and to evaluate the potential of Y-90 FAPI as a safe and effective targeted radionuclide therapy.

Y-90 FAPI Radionuclide TherapyExperimentalThis single-arm study includes patients with histopathologically confirmed advanced non-small cell lung cancer (NSCLC) who are eligible for radioligand therapy. All enrolled participants will receive Yttrium-90-labeled FAPI (90Y-FAPI) administered intravenously according to the study protocol. Treatment will be performed under standardized radiation safety conditions. Patients will undergo baseline clinical and imaging evaluation prior to therapy and will be followed prospectively with clinical assessment, laboratory tests, and serial imaging (including FAPI PET/CT and/or conventional imaging) to evaluate treatment response, biodistribution, dosimetry, safety, and tolerability. Adverse events will be monitored and recorded throughout the study period in accordance with CTCAE criteria.
