     Cytogen and Savient Sign Letter of Intent for Marketing of SOLTAMOX(TM)

       The first oral liquid tamoxifen in the U.S. represents a new option
            for women with breast cancer including patients unable to
                        tolerate solid oral dosage forms

PRINCETON AND EAST BRUNSWICK,  N.J.,  (FEBRUARY 8, 2006) -- Cytogen  Corporation
(NASDAQ:  CYTO) and Savient  Pharmaceuticals  (NASDAQ: SVNT) announced today the
execution  of a binding  letter of intent to  negotiate a  definitive  agreement
granting Cytogen exclusive marketing rights for SOLTAMOX(TM) (tamoxifen citrate)
in the United States.  SOLTAMOX, a cytostatic estrogen receptor  antagonist,  is
the first oral liquid hormonal  therapy approved in the U.S. It is indicated for
the treatment of breast cancer in adjuvant and metastatic settings and to reduce
the risk of breast cancer in women with ductal  carcinoma in situ (DCIS) or with
high risk of breast cancer.

"We are  extremely  pleased to  announce  our new  strategic  relationship  with
Savient,"  stated Michael D. Becker,  president and chief  executive  officer of
Cytogen.  "SOLTAMOX  represents  a novel and  synergistic  addition to Cytogen's
portfolio of oncology products."

Under the terms of the  final  transaction,  Cytogen  will pay to  Savient  upon
closing  an  upfront  licensing  fee of $2  million  and  additional  contingent
sales-based milestone payments of up to a total of $4 million. Savient will also
receive   royalties   on  net   sales  of   SOLTAMOX.   Additionally,   Rosemont
Pharmaceuticals  Ltd., a wholly owned  subsidiary of Savient,  will enter into a
supply  agreement  with  Cytogen  for the  manufacture  and supply of  SOLTAMOX.
Consummation  of the  transaction,  which  has been  approved  by the  boards of
directors of both  companies,  is subject to a number of  conditions,  including
satisfactory  completion  of  due  diligence  by  Cytogen  and  negotiation  and
execution of definitive licensing and supply agreements by Cytogen,  Savient and
Rosemont.  The parties expect the  transaction to close by March 30, 2006.  HSBC
Securities (USA) Inc. acted as an advisor to Cytogen.

"Our agreement with Cytogen  represents a major step forward in the  advancement
of  our   strategic   plan  to  position   Savient  as  an  emerging   specialty
pharmaceutical company," said Christopher Clement, President and Chief Executive
Officer  of  Savient.  "SOLTAMOX  is the first of what we hope will be many oral
liquid product entries into the U.S. from Rosemont in support of the strategy to
expand and maximize on the geographic  reach of its oral liquids  pharmaceutical
business and the niche product  opportunities  that Rosemont affords.  Cytogen's
established commercial infrastructure and demonstrated ability to maximize niche
oncology  product  opportunities  brings  together  the optimal  combination  of
experience  and  resources  to develop  and execute  the  successful  launch and
ongoing  commercialization  strategies that will bring this important product to
the many patients who need it," he said.





SOLTAMOX is a product of Rosemont  Pharmaceuticals  Ltd., Savient's wholly owned
subsidiary based in Leeds,  United Kingdom.  SOLTAMOX  received U.S.  regulatory
approval  in October  2005 and is licensed  in the United  Kingdom,  Ireland and
Germany.

About Hormone Therapy

Estrogen  is known to promote the growth of  approximately  two thirds of breast
cancers that contain estrogen or progesterone receptors. Breast cancer treatment
often involves agents designed to block the effect of estrogen or lower estrogen
levels. The antiestrogen drug that has been used most often is tamoxifen,  which
is taken  daily in pill form and has been  shown to  greatly  reduce the risk of
cancer returning and improves overall survival in all age groups.

About SOLTAMOX

Dysphagia  (swallowing  difficulty)  in women  suffering  from breast cancer can
arise from several causes, including patients receiving combination chemotherapy
and/or radiation  therapy for metastatic  breast cancer.  It may also arise from
either esophageal or stomach  metastasis.  Irrespective of the cause, many women
with  dysphagia  are unable to tolerate  the solid oral dosage forms of hormonal
therapy  and  might  benefit  from a  liquid  dosage  form,  such  as  SOLTAMOX.
Currently,  SOLTAMOX is the only liquid hormonal therapy  solution  available in
the United Kingdom, Ireland and Germany, and will soon be launched in the United
States.  The availability of an oral liquid dosing option could allow more women
to benefit from hormonal treatment for estrogen receptor positive breast cancer.

Important safety information for SOLTAMOX

Use of SOLTAMOX  in risk  reduction  setting  (women at high risk for cancer and
women  with DCIS) has shown to cause  cancer of the  uterus,  stroke,  and blood
clots.  The benefits of SOLTAMOX  outweigh its risks in women already  diagnosed
with breast cancer. SOLTAMOX should not be used in women who require concomitant
use of  coumarin-type  anticoagulant,  or in women  with  history  of deep  vein
thrombosis  or  pulmonary  embolus.  Women  who are  pregnant  or plan to become
pregnant should not take SOLTAMOX. Cataracts and cataract surgery can also occur
more frequently with SOLTAMOX.  The most frequently  reported adverse  reactions
with SOLTAMOX were hot flashes and vaginal discharge.
