BioNTech : to Evaluate NanoTag’s Target Labeling System in Different Therapeutic Areas

MAINZ, Germany and GÖTTINGEN, Germany, May 22, 2024 - BioNTech SE (Nasdaq: BNTX, "BioNTech") and NanoTag Biotechnologies GmbH ("NanoTag"), a biotechnology company developing single-domain antibodies, today announced that BioNTech has exercised an exclusive option right under a previously signed Research Collaboration and License Agreement. BioNTech gains rights to exclusively evaluate NanoTag's target labeling system "ALFA" across indications in oncology and infectious diseases in both a preclinical and clinical setting.

The ALFA tagging system can be used to biologically label a target of interest in the laboratory setting (i.e., a protein on the cell membrane) with a protein tag. Protein tags are either short peptides or entire proteins fused to a protein of interest, providing an approach to isolate or track proteins in the cell. The tag in the ALFA system is bound specifically by a designed set of antibodies. The high specificity of the tag-antibody binding has the potential for different use cases that BioNTech intends to evaluate, including drug delivery.

Under the terms of the initial agreement signed in 2022, NanoTag will now receive an option exercise fee of EUR 1 million from BioNTech for the use of the ALFA system in its candidate development, and potential additional development, regulatory and commercial milestone payments, and royalty payments. BioNTech may advance any number of products under the licensing agreement.
