A proprietary drug delivery technology that takes advantage of tissue targeting via a modified / optimized antibody (3E10) that has intracellular-delivery capabilities dependent on membrane expression of the nucleoside transporter (ENT2). Because the ENT2 transporter is naturally enriched in muscle and neurons (and elevated in certain cancers), Valerion is able to generate proprietary product candidates utilizing substrates (proteins, enzymes, oligonucleotides, etc.) not previously deliverable to target tissues (ex. heart & skeletal muscle fibers); thereby, providing a novel way to treat a number of diseases with limited or no current therapeutic options.
