Description: FAPI-04, also known as FAPi-4, is a quinoline-based theranostic ligands for the targeting of Fibroblast Activation Protein. FAPI-4 was identified as the most promising tracer for clinical application. Compared with the previously published ligand, FAPI-4 showed excellent stability in human serum, higher affinity for FAP as opposed to CD26, and slower excretion in vitro. FAPI-4 represents a promising tracer for both diagnostic imaging and, possibly, targeted therapy of malignant tumors with a high content of activated fibroblasts, such as breast cancer.

More Info: Fibroblast activation protein (FAP) is overexpressed in cancer-associated fibroblasts and is involved in a variety of tumor-promoting activities such as matrix remodeling, angiogenesis, chemotherapy resistance, and immunosuppression. Because FAP shows low expression in most normal organs, it presents an interesting target for imaging and endoradiotherapy.

Biological target: seMpai is an AkaLumine analog, acting as an NIR emission luciferin.
In vitro activity: To be determined
In vivo activity: This study demonstrated the ability of FAPI-04 to detect primary and metastatic renal cell carcinoma (RCC) lesions in patients, presenting higher median values of SUVmax and tumor-to-background ratio compared to the standard FDG-PET/CT. FAPI-04 PET/CT displayed higher SUVmax values in the lungs and revealed potential staging insights for primary lesions based on TNM stages. FAPI-04 PET/CT has potential as a complementary imaging modality. Reference: Eur J Nucl Med Mol Imaging. 2023 Oct 7. https://pubmed.ncbi.nlm.nih.gov/37803246/
