About Enzon

Enzon Pharmaceuticals, Inc. is a biotechnology company that had been dedicated to the research and development of innovative therapeutics for patients with high unmet medical needs.  Enzon receives royalty revenues on seven marketed products that utilize its proprietary Customized PEGylation Linker Technology (Customized Linker Technology®) platform, namely PegIntron®, Sylatron®, Macugen®, CIMZIA®, OMONTYS®*, Oncaspar and Adagen.


In December 2012, the Company announced that its Board of Directors retained Lazard Frères & Co. LLC (“Lazard”) to act as financial advisor in a review of the possible sale or disposition of one or more corporate assets or a sale of the Company and that its Board of Directors established a special committee to oversee the sale review process. In connection with the sale review process, Enzon has substantially suspended all clinical development activities with a goal of conserving capital and maximizing value returned to its stockholders. The sale review process entails numerous significant risks and uncertainties. There can be no assurance that Enzon’s sale review process will result in any transaction.


* On February 23, 2013, Affymax and Takeda announced a nationwide voluntary recall of all lots of OMONTYS (peginesatide) injection to the user level as a result of new postmarketing reports regarding serious hypersensitivity reactions, including anaphylaxis, which can be life-threatening or fatal. This recall will negatively affect the Company’s future royalty revenues from OMONTYS.
