PROGENICS PHARMACEUTICALS REPORTS

FIRST QUARTER 2007 RESULTS

Tarrytown, NY, May 9, 2007 - Progenics Pharmaceuticals, Inc. (Nasdaq: PGNX) today announced its results of operations for the quarter ended March 31, 2007.

Revenues for the quarter ended March 31, 2007 totaled $17.6 million compared to revenues of $11.0 million for the same period in 2006. Revenues for the quarter primarily reflect reimbursement by Wyeth for development work performed by the Company under our methylnaltrexone collaboration ($10.5 million in 2007 and $4.1 million in 2006), recognition of a portion of the $60 million upfront payment received from Wyeth in December 2005 ($5.0 million in 2007 and $4.4 million in 2006) and funding from government grants and contracts ($2.1 million in 2007 and $2.5 million in 2006).

The Company’s expenses for the first quarter of 2007 were $29.9 million, compared to $15.6 million for the first quarter of 2006, including $2.9 million of non-cash expense for share-based compensation in 2007, compared to $2.2 million for the same period in 2006. The increase in expenses was primarily due to a $12.6 million increase in research and development expenses related to our collaboration with Wyeth, preparation for clinical trials for our other product candidates and an increase in headcount. General and administrative expenses also increased $1.7 million, primarily due to an increase in headcount.

The Company reported a net loss of ($10.4 million) or ($0.40) per share (basic and diluted) for the first quarter of 2007, compared to a net loss of ($2.6 million) or ($0.10) per share (basic and diluted) for the first quarter of 2006. At the end of the first quarter of 2007, Progenics had $140.1 million in cash, cash equivalents and marketable securities compared to $149.1 million at December 31, 2006.

Developments in early 2007

·   Progenics submitted a New Drug Application for marketing approval to the U.S. Food and Drug Administration for the subcutaneous formulation of methylnaltrexone for the treatment of opioid-induced constipation in patients receiving palliative care.

·   Wyeth Pharmaceuticals and Progenics announced that Wyeth had begun clinical testing of a new formulation of oral methylnaltrexone for the treatment of opioid-induced constipation. Preliminary results from a phase 2 trial conducted by Wyeth showed that the initial formulation of oral methylnaltrexone tested was generally well tolerated, but did not exhibit sufficient clinical activity to advance into phase 3 testing.

·   Progenics announced positive results from a phase 1b trial of PRO 140, a humanized monoclonal antibody designed to inhibit entry of HIV (human immunodeficiency virus) into healthy cells. Results showed that patients receiving a single 5.0 mg/kg dose, the highest dose tested, achieved an average maximum decrease of viral concentrations in the blood of 98.5%. In these patients, reductions in viral load of greater than 90%, on average, persisted for two-to-three weeks after receiving a single dose of the drug. PRO 140 was generally well tolerated in this phase 1b proof-of-concept study.

“Progenics plans to be very busy in 2007,” said Paul J. Maddon, Progenics’ Founder, Chief Executive Officer and Chief Science Officer. “We experienced our most significant milestone in the Company’s history during the first quarter, the filing of our first New Drug Application for the subcutaneous formulation of methylnaltrexone in patients receiving palliative care. In May, our progress continued as we reported positive data in our phase 1b clinical trial of PRO 140, with results representing the largest reported single-dose mean reduction in viral load for any HIV agent. We expect the balance of 2007 to remain active, including the planned submission of the subcutaneous form of methylnaltrexone for regulatory marketing approval in Europe, completion of pivotal phase 3 studies of methylnaltrexone in post-operative ileus, the initiation of clinical trials for PRO 140, and the filing of an Investigational New Drug application for our antibody-drug conjugate for metastatic prostate cancer.”
