Novartis signs deal with iTheranostics to develop, commercialise compounds targeting FAP

Novartis has obtained exclusive worldwide rights to develop and commercialise therapeutic applications for a library of Fibroblast Activation Protein (FAP) targeting agents including FAPI-46 and FAPI-74, through an assignment agreement with iTheranostics, an affiliate of SOFIE Biosciences. The FAP assets were originally developed at the University of Heidelberg. The agreement also includes co-exclusive rights for Novartis to develop imaging applications for these assets.

Fibroblast activation protein (FAP) is a cell-surface protein expressed at low levels in most normal adult tissues, but overexpressed in common cancers, particularly on cancer-associated fibroblasts that form the tumour stroma, which is essential for growth. High FAP expression on cancer-associated fibroblasts is generally associated with worse prognosis in solid tumours due to promotion of tumorigenesis and progression.

“We continue to invest in radioligand therapy as one of the four unique platforms of Novartis Oncology. We believe working across multiple approaches is the key to reimagining cancer care,” said Susanne Schaffert, President, Novartis Oncology. “FAP is an exciting target and these agents are a great fit with our radioligand therapy pipeline, which we are actively investigating across multiple tumour types. We believe this technology has the potential to transform many patients’ lives.”

Targeted radioligand therapy is a type of precision medicine combining two key elements: a targeting compound, or ligand, and a radioactive isotope, causing DNA damage that inhibits tumour growth and replication. These targeted drugs bind to markers or proteins over-expressed by certain tumours, or tumour-associated tissue, such as stroma. Due to the high-affinity of these agents for specific tumour cells or associated tumour tissue, surrounding healthy tissue is less affected.
