On December 2, 2021 ITM Isotope Technologies Munich SE, a leading radiopharmaceutical biotech company and Navigo Proteins GmbH, a premier protein engineering company developing optimized scaffold protein-based affinity ligands called Affilin molecules from its Precision Targeting toolbox, reported a research collaboration for the development of a fibroblast activation protein (FAP)-targeted radiopharmaceutical program for the treatment of solid tumors (Press release, ITM Isotopen Technologien Munchen, DEC 2, 2021, View Source [SID1234596411]). The program is planned to be added to ITM’s growing proprietary pipeline of Targeted Radionuclide Therapies spanning multiple radioisotopes and targeting molecules for optimal therapeutic effect. FAP-Targeted Radionuclide Therapy is a promising new approach to treating cancer within the precision oncology field.

Under the terms of the agreement, Navigo’s proprietary protein engineering platform will be used to develop and select a FAP-targeting Affilin molecule which will then be coupled with a therapeutic radioisotope provided by ITM. Following candidate selection, ITM will have the exclusive rights to further advance the radiolabeled FAP-specific Affilin through clinical testing in potentially multiple cancer indications. The agreement also includes a non-exclusive license for diagnostic use in radio-imaging. Further details of the agreement were not disclosed.
"FAP-targeting approaches have received heightened attention for good reason. We believe this approach holds the potential to treat a wide range of cancer indications. As such, we look forward to exploring this innovative targeted radiopharmaceutical approach for our growing precision oncology pipeline, further expanding its reach and breadth. We believe that developing a new candidate by combining our radioisotopes with an Affilin ligand targeting FAP has the opportunity to make a difference in the lives of patients," commented Steffen Schuster, CEO of ITM.
FAP is a highly attractive tumor target for Targeted Radionuclide Therapy that is preferentially expressed on cancer cells and in particular on cancer associated fibroblasts (CAFs). It is detectable in most epithelial cancers, including over 90% of breast, lung, colorectal and pancreatic carcinomas. High expression levels are associated with poor prognosis, and therefore warrant additional medical research and focus. ITM and Navigo are addressing this urgent need through their research collaboration and combined efforts to develop a promising FAP-targeted radiopharmaceutical.
"We welcome the opportunity to extend our productive partnership with ITM with yet another promising project. We strongly believe in the potential of our technology to generate high-quality Affilin ligands targeting FAP and capable of breaking the tumor microenvironment. By joining forces with ITM, we are fully equipped to build a strong FAP-targeting candidate, that ITM will then advance through clinical development," said Henning Afflerbach, CEO of Navigo Proteins.
The therapeutic candidate developed together by ITM and Navigo will enable a direct attack against tumor cells by irradiating them via crossfire effects in a highly precise manner. Through the direct depletion of CAFs it additionally provides a new access point to modify the tumor microenvironment in which CAFs play a central role in upholding the barrier for effective immune cell infiltration.
This agreement further strengthens the existing partnership between the two organizations, combining ITM’s deep expertise in developing promising Targeted Radionuclide Therapies for cancer patients with Navigo’s proprietary Affilin molecules and protein engineering proficiency.
