PEGylation attaches polyethylene glycol to therapeutic molecules to potentially extend their time in the body and improve treatment characteristics. The company’s historical product portfolio included ADAGEN (pegademase bovine), a treatment for adenosine deaminase deficiency; ONCASPAR (pegaspargase), used in the treatment of acute lymphoblastic leukemia; and other PEGylated therapies developed independently or with pharmaceutical partners. Enzon also licensed its PEGylation technology to other companies for use in drug development. Enzon was based in Bridgewater, New Jersey, and served the biopharmaceutical and healthcare markets through products and technology partnerships. The company later significantly reduced its operations and pursued strategic alternatives, so historical descriptions of its business may not reflect an active operating pharmaceutical company today.AI Generated.
