VERAXA and Navigo Initiate Collaboration to Establish Pre-Targeting Strategies for Novel Affilin® Radio Conjugates

The agreement brings together Navigo Protein’s Affilin® platform with VERAXA’s proprietary click chemistry platform and conjugation expertise.

HEIDELBERG, GERMANY, December 12, 2024 /EINPresswire.com/ -- HEIDELBERG, and HALLE, Germany, December 12, 2024 -- VERAXA Biotech AG, an emerging leader in designing novel cancer therapies, and Navigo Proteins GmbH, an innovator developing next-generation targeted radiotheranostics, announced today the initiation of a research collaboration to evaluate a novel approach for precisely diagnosing and treating challenging cancers while reducing damage to healthy tissues using radioimmunoconjugates (RICs). The agreement brings together Navigo Protein’s Affilin^® platform capable of providing highly specific targeted radiotheranostics with VERAXA’s proprietary click chemistry platform and conjugation expertise.

Dr. Ulrich Haupts, CSO and Managing Director at Navigo Proteins, commented: “Today’s research alliance with VERAXA aims to evaluate a novel strategy for the use of our Affilin^® platform in Theranostics. Affilin^® ligands strike a well-defined balance between being of smaller size to increase tumor penetration, while exhibiting a longer half-life compared to shorter peptides used elsewhere in the industry. Taken together, our joint capabilities and platforms could deliver a series of next-generation radiopharmaceutical compounds by incorporating a novel pre-targeting strategy.”

“While VERAXA is focused on developing ADCs and bispecific T cell engagers, collaborating with Navigo Proteins in radioimmunoconjugates provides an ideal platform to showcase the capabilities of our technology suite across different anti-cancer strategies,” commented Christoph Antz, Ph.D., CEO and Co-Founder of VERAXA. “The fact that our platform features one of the fastest click-chemistry reactions on the market has significance in the pre-targeting setting. The speed of the in vivo conjugation step, maximum and stable saturation of the tumor-bound Affilins^® and rapid clearance of the excess radioligand are essential success factors for such therapies.”

Pre-targeting strategies rely on separate injection of a tumor-targeting agent and subsequent delivery of a radioactive payload. In the collaboration announced today, Affilin^® molecules selected by Navigo Proteins against tumor-associated antigens would be administered in the first step. VERAXA’s patented trans-cyclooctene (TCO)-based bioorthogonal click chemistry technology would then be applied to facilitate the in vivo conjugation step of the radioligand to the Affilin^® via a secondary binding site. Using such a two-component system has the potential to enhance the targeting of cancer cells by delivering targeted radiation directly to the tumor, while minimizing the exposure of healthy tissues to radiation.
