Progenics Pharmaceuticals, Inc. (Nasdaq: PGNX) today announced its results of operations for the third quarter and nine months ended September 30, 2008.

Revenues for the third quarter totaled $17.5 million, compared to $17.0 million for the same period of 2007. For the nine months ended September 30, 2008, the Company reported revenues of $60.8 million compared to $60.1 million for the comparable period of 2007. Revenues for the three-month and nine-month periods ended September 30, 2008 and 2007 reflect the following:

• Reimbursement from Wyeth Pharmaceuticals, a division of Wyeth (NYSE: WYE), of development work performed by Progenics under their RELISTOR^® collaboration: Reimbursement was recognized in the amounts of $3.9 million and $11.3 million for the third quarters of 2008 and 2007, respectively. For the nine months ended September 30, 2008 and 2007, $21.8 million and $30.8 million was recognized, respectively.
• Amortization of the upfront payment from Wyeth under the RELISTOR collaboration: Of the $60.0 million upfront payment received from Wyeth in December 2005, $2.1 million and $3.2 million was recognized in the third quarters of 2008 and 2007, respectively. For the nine months ended September 30, 2008 and 2007, $8.1 million and $13.1 million was recognized, respectively.
• Milestone payments from Wyeth: Milestone payments related to the European and U.S. approvals of subcutaneous RELISTOR totaled $10.0 million in the third quarter of 2008 and $25.0 million in the nine months ended September 30, 2008. Milestone payments of $9.0 million were received during the nine months ended September 30, 2007.
• Royalty income payments from Wyeth: Royalty income based on net sales of subcutaneous RELISTOR was recorded in the amounts of $44,000 for the third quarter of 2008 and $86,000 for the nine months ended September 30, 2008. Cumulative royalties of $352,000 were deferred at September 30, 2008 and are expected to be recognized as royalty income over the period of our development obligations relating to RELISTOR.
• Funding from government grants and contract: These revenues, related to the Company’s proprietary programs in virology and oncology, totaled $1.4 million and $2.5 million in the third quarters of 2008 and 2007, respectively. For the nine months ended September 30, 2008 and 2007, $5.7 million and $7.1 million were earned, respectively.

"We have been able to maintain a healthy balance sheet while advancing our product pipeline because of the continued funding by Wyeth of our lead program, RELISTOR, together with payments for achieving milestones and royalties on commercial sales,” said Paul J. Maddon, M.D., Ph.D., Founder, Chief Executive Officer and Chief Science Officer, Progenics Pharmaceuticals, Inc. "This quarter we achieved another development milestone as PSMA ADC, our prostate cancer therapy, entered phase 1 testing. Going forward, we will look to leverage the extensive drug development expertise we have gained from the RELISTOR program to develop our virology and oncology pipeline.”

Expenses for the third quarter of 2008 were $31.2 million, compared to $34.4 million for the third quarter of 2007. For the nine months ended September 30, 2008, expenses totaled $95.9 million, compared to $93.9 million for the same period of 2007. Research and development expenses, including license fees and royalty expense, decreased $2.5 million in the third quarter of 2008, compared to the third quarter of 2007, and were at approximately the same levels for the nine months ended September 30, 2008 and 2007. The decrease in the third quarter Research and development expenses resulted primarily from a decrease in RELISTOR clinical trial activity, partially offset by an increase in headcount. General and administrative expenses decreased for the three months but increased for the nine months ended September 30, 2008, compared to the same periods of 2007. The third quarter decrease in General and administrative expenses was primarily due to a decrease in share-based compensation expense while the year-to-date increase was primarily due to an increase in headcount and consulting and professional fees.

Third quarter 2008 net loss was $12.2 million, compared to $15.6 million for the same period of 2007. Net loss per share was ($0.41), basic and diluted, for the third quarter of 2008, compared to a net loss per share of ($0.58), basic and diluted, for the same period of 2007. The net loss for the first nine months of 2008 was $30.1 million, compared to a $28.4 million net loss for the same period of 2007. Net loss per share for the first nine months of 2008 was ($1.02), basic and diluted, compared to a net loss per share of ($1.07), basic and diluted, for the same period of 2007.

In April 2008, Progenics’ Board of Directors approved a share repurchase program to acquire up to $15.0 million of the Company’s outstanding common shares, funding for which came from a $15.0 million milestone payment from Wyeth for the receipt of marketing approval of the subcutaneous form of RELISTOR in the U.S. Progenics repurchased 200,000 shares during the three months ended September 30, 2008 for a total purchase price of $2.7 million. The Company has $12.3 million remaining available for purchases under the program. Purchases under the program may be discontinued at any time.

Progenics ended the third quarter of 2008 with cash, cash equivalents and marketable securities of $134.6 million, compared to $170.4 million at December 31, 2007.

Third Quarter 2008 Highlights

• In September, Progenics’ wholly owned subsidiary, PSMA Development Company (PDC), initiated a phase 1 dose-escalation clinical study of its prostate-specific membrane antigen (PSMA) antibody-drug conjugate (ADC). PSMA ADC is an investigational therapy that combines a fully human monoclonal antibody with a derivative of auristatin, a chemotherapeutic agent. Unlike traditional chemotherapy, PSMA ADC is designed to deliver the drug selectively to prostate cancer cells by targeting PSMA, a protein abundantly expressed on the surface of prostate cancer cells as well as on the neovasculature of many types of solid tumors. The study is designed to assess the safety, tolerability and initial clinical activity of PSMA ADC during an initial 12-week treatment period, followed by the option to continue therapy for a total of 12 months.
• Also in the third quarter, enrollment was completed in a phase 3 clinical study of the subcutaneous form of RELISTOR for the treatment of opioid-induced constipation in patients with chronic pain not related to cancer, such as chronic severe back pain.

Recent Highlights

• In October, Progenics entered into an exclusive license agreement with Ono Pharmaceutical Co., Ltd., under which Ono acquired the rights to the subcutaneous form of RELISTOR in Japan, where it plans to develop and commercialize this drug for the treatment of opioid-induced constipation. Under the collaboration terms, Progenics is entitled to receive a $15.0 million upfront payment, development and commercialization milestone payments and royalties on net sales.
• In October, Progenics announced the completion of enrollment in two phase 2 studies of subcutaneous and intravenous PRO 140, an HIV entry inhibitor and humanized monoclonal antibody targeting the entry co-receptor CCR5. Interim data from these two studies showed that both forms of PRO 140 exhibited potent and prolonged activity and were generally well tolerated. Interim data from the study of intravenous PRO 140 were presented in a "late-breaker” session at the 2008 joint meeting of the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) and the Infectious Diseases Society of America (IDSA).
• In November, Progenics also announced the selection of a proprietary small-molecule drug candidate, designated PRO 206, a novel HCV entry inhibitor for clinical development as a treatment of hepatitis C virus (HCV) infection. Pre-clinical results supporting the development of PRO 206 were presented at the annual meeting of the American Association for the Study of Liver Diseases (AASLD) in San Francisco. PRO 206 is an orally available viral-entry inhibitor designed to prevent HCV from entering and infecting healthy liver cells. PRO 206 represents an innovative approach to HCV therapy as it specifically blocks the hepatitis C virus. HCV currently is treated with interferon in combination with ribavirin, non-specific antiviral agents that are associated with significant side effects and failure rates. Targeted antiviral agents are widely viewed as a promising approach to improving treatment of HCV infection.
• Also in November, Progenics’ wholly owned subsidiary, PDC, plans to initiate a 29-week, phase 1, multi-dose, dose-escalation study of a therapeutic vaccine for prostate cancer, PSMA-VRP. PSMA-VRP is designed to induce both antibodies and killer T-cells that can recognize and potentially eliminate PSMA-positive prostate cancer cells in a vaccinated patient. The phase 1 clinical study will assess the safety, tolerability, initial immunogenicity and clinical activity of PSMA-VRP in patients with progressive, castrated, metastatic prostate cancer. The PSMA-VRP vaccine is based on the platform alphavirus replicon vector technology system (a non-replicating viral vector system), and was developed under license from AlphaVax, Inc., located in Research Triangle Park, NC.

Executive Management Promotions

Progenics also announced five recent executive promotions in Corporate Strategy, Research and Development, Manufacturing, Quality and Regulatory Affairs.

"In recent years, Progenics has benefited from the collective knowledge and experience of its management team, resulting in our first commercial product approved earlier this year,” said Dr. Maddon. "Beyond our RELISTOR franchise, these five members of executive management will be instrumental in developing the significant potential in our pipeline.”
