Enzon Pharmaceuticals, Inc. (Nasdaq: ENZN) today announced its financial results for the third quarter of 2010. Enzon reported a loss from continuing operations of $8.4 million or $0.14 per diluted share, as compared to a loss of $11.5 million or $0.26 per diluted share for the third quarter of 2009. As of September 30, 2010, the Company’s cash and cash equivalents, short-term investments, and marketable securities totaled $484.6 million.

“Our intensified focus on our pipeline of innovative oncology programs is translating into encouraging results as we advance our clinical programs and continue to share new preclinical data demonstrating the potential of our pipeline,” stated Alex Denner, Chairman of the Board. “In addition, we continue to realize the operating efficiencies associated with the strategic restructuring initiatives enacted at the beginning of the year, which established an operating structure appropriately aligned with our development activities. With a strong cash position, we are well-positioned to execute our objectives focused on developing and advancing a high-value pipeline of oncology programs.”

  • The Company continues to enroll patients in its ongoing clinical trials of PEG-SN38, consisting of a Phase II colorectal cancer study, a Phase II metastatic breast cancer and a Phase I pediatric cancer study. Enzon recently announced the publication of preclinical data in the October 1, 2010 issue of Clinical Cancer Research that are supportive of the Phase I PEG-SN38 study in pediatric cancer, demonstrating that PEG-SN38 led to significantly greater tumor regression as compared to CPT-11 (irinotecan) in both in vitro and in vivo models of pediatric neuroblastoma.
  • Enrollment continues to progress in the Company’s Phase I clinical trials of the HIF-1 alpha and survivin antagonists in adult patients with solid tumors and lymphomas.
  • Enzon recently announced that data from three preclinical mRNA programs have been accepted for poster presentation at the EORTC-NCI-AACR International Symposium on Molecular Targets and Cancer Therapeutics, which is being held November 16-19 in Berlin, Germany.
  • Enzon has been invited to present its LNA-based mRNA antagonists at the November EuroTIDES meeting in Barcelona, Spain.
  • The Company completed exploration of the possible sale of its PEGINTRON royalty stream and determined that currently available options do not reflect the value of an expanded market for the product that may result from the potential introduction of new combination therapies in the hepatitis C virus market. As a result, the Company has concluded it will not currently pursue the sale of its PEGINTRON royalty stream.

The total amount of expense related to Enzon's pipeline programs increased to $14.2 million in the third quarter of 2010, compared to $11.4 million in the third quarter of 2009, partly due to increased investments in its clinical activities for PEG-SN38.

The Company also incurred an expense of $0.5 million during the quarter ended September 30, 2010 related to other research efforts.
