Enzon Pharmaceuticals, Inc. (Nasdaq: ENZN) today announced its financial results for the second quarter of 2010. For the second quarter of 2010, Enzon reported a loss from continuing operations of $5.4 million or $0.09 per diluted share, as compared to a loss of $19.7 million or $0.43 per diluted share for the second quarter of 2009. “Enzon made significant progress over the second quarter in realigning its operations as a biopharmaceutical company,” said Alex Denner, Ph.D., Chairman of the Board. “The Company is now focused on building value through its novel pipeline of oncology therapeutics and returning value from its other assets. Enzon also improved its corporate governance standards last quarter by eliminating board classes and instituting annual elections for our entire slate of directors. Governance was further enhanced with the addition of Drs. Thomas Deuel and Richard Young as directors, each of whom brings outstanding scientific credentials and experience to the Board.” Summary of Financial ResultsResearch and Development Enzon’s research and development pipeline consists of the following programs: PEG-SN38, HIF-1 alpha antagonist, survivin antagonist and an additional six mRNA antagonists utilizing the LNA technology. The total amount of expense related to Enzon's pipeline programs was $10.1 million in the second quarter of 2010, compared to $11.8 million in the second quarter of 2009. The second quarter 2009 expense was higher due to the costs associated with the purchase of materials and manufacturing of HIF-1 alpha and survivin antagonist drug supply for Phase I clinical trials. Partially offsetting this was the $1.0 million milestone expense related to HER3 RNA antagonist in the second quarter of 2010. The amount attributable to the Company’s PEG-SN38 program for the second quarter of 2010 was $4.4 million as compared to $3.0 million spent in the second quarter of 2009. Enzon continues to enroll patients in its ongoing PEG-SN38 studies. Enrollment is ongoing in the Phase II colorectal cancer study, as well as the Phase II metastatic breast cancer and the Phase I pediatric cancer studies, both of which were initiated in early 2010.
