Item 9.  Regulation FD Disclosure.

     On July 15, 2004, Progenics Pharmaceuticals, Inc. announced encouraging
preliminary results with a novel HIV/AIDS vaccine. Laboratory tests in animals
showed that the vaccine induced the production of anti-HIV antibodies. The
Company presented these findings today at the XV International AIDS Conference
in Bangkok. The research, a collaborative effort between Progenics and Weill
Medical College, is funded by a $28.6 million contract awarded to Progenics by
the National Institutes of Health, an agency of the Department of Health and
Human Services. A copy of the press release is attached as Exhibit 99.1.

     The information furnished pursuant to Item 9 in this Form 8-K shall not be

Securities Act of 1933 or the Securities Exchange Act of 1934. We undertake no
duty or obligation to publicly update or revise the information furnished
pursuant to Item 9 in this Form 8-K.
