Aizen Therapeutics is a biotechnology company pioneering the development of Mirror Peptides, a novel class of synthetic, fully D-amino acid peptides that offer superior therapeutic stability and reduced immunogenicity compared to natural peptides. Their proprietary DaX™ platform, leveraging generative AI and advanced computational models, enables rapid design-build-test cycles (~4 weeks) with high hit rates for drug development targeting neurological disorders, oncology, and genetic diseases. This platform enhances drug specificity, half-life, and solubility, positioning Aizen as a leader in next-generation peptide therapeutics with a focus on improving patient safety and efficacy.
