PHAEX Polymers

PHAEX is a German biotechnology company specializing in the development and production of high-purity poly(2-oxazoline)s (POx) for pharmaceutical and medical applications. Spun out from the Leibniz Institute of Polymer Research Dresden, the company provides a versatile polymer platform designed to overcome the limitations of conventional delivery systems like polyethylene glycol (PEG). Their technology enables the creation of advanced drug delivery vehicles, including high-capacity micelles and polymer-drug conjugates, which improve the solubility and stability of complex therapeutics. PHAEX focuses on enhancing the delivery of small molecules, peptides, and nucleic acids, particularly in the fields of oncology and inflammatory diseases. In addition to its internal development programs, the company offers custom polymer synthesis and analytical services to global pharmaceutical partners. By leveraging the unique properties of POx, PHAEX aims to enable next-generation nanomedicines with superior safety and efficacy profiles.
