CYTOGEN SELLS OWNERSHIP IN PSMA DEVELOPMENT JOINT VENTURE TO PROGENICS
Terms include upfront cash and milestone payments to Cytogen potentially
totaling more than $65 million.
PRINCETON, N.J., (APRIL 24, 2006) -- Cytogen Corporation (NASDAQ: CYTO) today
announced the sale of its 50% ownership interest in PSMA Development Company LLC
(PDC), the company's joint venture with Progenics Pharmaceuticals, Inc. (NASDAQ:
PGNX) for the development of in vivo cancer immunotherapies based on
prostate-specific membrane antigen (PSMA).
Under the terms of the agreement, Cytogen sold its 50% interest in PDC to
Progenics for an upfront cash payment of $13.2 million, potential future
milestone payments totaling up to $52 million payable upon regulatory approval
and commercialization of PDC products, and an undisclosed royalty on future PDC
product sales. Cytogen will no longer be responsible for funding PDC. In 2005,
Cytogen's share of the loss associated with PDC was $3.18 million.
"PSMA is an important and broadly studied target, and the terms of our agreement
with Progenics reflect both companies' recognition of the potential value of
PSMA products", said Michael D. Becker, president and chief executive officer of
Cytogen. "Through this transaction, Cytogen realizes an attractive valuation for
its 50% ownership in PDC and retains a financial interest in PDC's future
success. In addition, we retain the right to develop our CYT-500 radiolabeled
antibody program. The agreement also reduces Cytogen's investment in early-stage
projects and provides additional capital to support our core commercial business
strategy."
About PSMA
PSMA is a protein abundantly expressed on the surface of prostate cancer cells,
with an increased expression in high-grade cancers, metastatic disease and
hormone-refractory prostate cancer. PSMA is also present at high levels on the
newly formed blood vessels, or neovasculature, needed for the growth and
survival of many solid tumors. In contrast to other prostate-related antigens
such as prostate-specific antigen (PSA), prostatic acid phosphatase (PAP) and
prostate secretory protein, PSMA is a membrane glycoprotein that is not
secreted. These unique attributes make PSMA an excellent target for monoclonal
antibody diagnostic and therapeutic options in prostate and potentially other
cancers.
About CYT-500
In April 2006, Cytogen announced the submission of an Investigational New Drug
(IND) application to the U.S. Food and Drug Administration (FDA) for CYT-500,
the company's lead therapeutic candidate targeting PSMA. Subject to FDA
acceptance and Institutional Review Board (IRB) approval at the planned clinical
site, Cytogen expects to begin the first U.S. Phase I clinical trial of CYT-500
in patients with hormone-refractory prostate cancer. CYT-500 incorporates the
same monoclonal antibody utilized in Cytogen's PROSTASCINT(R) (capromab
pendetide) molecular imaging agent, but is linked to a therapeutic as opposed to
an imaging payload. This novel product candidate is designed to enable targeted
delivery of a cytotoxic agent to PSMA-expressing cells. Cytogen retains full and
exclusive development rights to CYT-500.
