              CYTOGEN REVISES THIRD QUARTER 2005 FINANCIAL RESULTS


PRINCETON, N.J., (November 14, 2005) -- Cytogen Corporation (Nasdaq: CYTO) today
announced that it has revised its  previously  reported  consolidated  financial
results  for the third  quarter  and nine  months  ended  September  30, 2005 to
reflect the  recognition  of a warrant  liability and a decrease in the value of
the warrant  liability  related to warrants  issued by the company in connection
with its sale of common  stock in July and August  2005.  This has  reduced  the
company's  net loss for the third  quarter and nine months ended  September  30,
2005 by $703,000.

Cytogen  is now  reporting  a net loss of $7.1  million,  or $0.40 per basic and
diluted  share,  in the third  quarter of 2005,  compared  to a net loss of $7.8
million, or $0.44 per basic and diluted share, which the company had reported on
November 2, 2005.  For the nine months ended  September 30, 2005,  the company's
total net loss was $21.5 million, or $1.31 per basic and diluted share, compared
to $22.2 million, or $1.36 per basic and diluted share, which it had reported on
November  2, 2005.  This  revision  does not affect the 2004 third  quarter  and
nine-month  losses of $5.6 million,  or $0.36 per basic and diluted  share,  and
$14.3 million, or $0.99 per basic and diluted share, respectively.

The  decrease  in net loss and net loss per basic  and  diluted  share  from the
consolidated financial results for the three and nine months ended September 30,
2005  announced  on  November  2, 2005 was due to the  recognition  of a warrant
liability  and a  decrease  in the value of the  warrant  liability  related  to
warrants  issued by the company in July 2005 and August 2005 in connection  with
the  company's  sale of common stock and warrants  that provided net proceeds to
Cytogen of  approximately  $13.9  million.  The  company  has now  recorded  the
warrants as a liability at their fair value using a Black-Scholes option-pricing
model and will  remeasure  them at each  reporting  period  until  exercised  or
expired.  Changes  in  the  fair  value  of the  warrants  are  reported  in the
statements of operations as non-operating  income or expense.  For the three and
nine months ended  September 30, 2005,  the company  reported a gain of $703,000
related to the decrease in the fair value of these warrants from issuance dates.
