        Nasdaq notification has no effect on the listing of the Company&#8217;s&#8217;s common stock
        at this time and the Company will continue to trade on the Nasdaq Global Market
        under the symbol CYTO.&#160;&#160;&#160;The letter states that the Company has
        180 calendar days, or until May 5, 2008, to regain compliance with the minimum
        bid price&#160;requirement of $1.00 per share.&#160;&#160;The Company can
        achieve compliance, if at any time before May 5, 2008, Cytogen&#8217;s common stock
        closes at $1.00 per share or more for at least 10 consecutive business
        days.</font></div>

      <div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 36pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;">If
        compliance with Nasdaq&#8217;s Marketplace Rules is not achieved by May 5, 2008,
        Nasdaq will provide notice that the Company&#8217;s common stock will be delisted from
        the Nasdaq Global Market.&#160;&#160;In the event of such notification, the
        Company would have an opportunity to appeal Nasdaq&#8217;s determination or to apply
        to transfer its common stock to the Nasdaq Capital Market.&#160;&#160;If the
        Company&#8217;s appeal for continued listing on the Nasdaq Global Market is not
        granted and the Company is not permitted to transfer to the Nasdaq Capital
        Market, the common stock may trade on the National Association of Securities
        Dealers&#8217; OTC Bulletin Board.</font></div>

        can
        be no assurance that the Company will be able to maintain the listing of its
        Common Stock on the Nasdaq Global Market.&#160;&#160;Delisting from Nasdaq
        Global Market would make trading the Company&#8217;s common stock more difficult for
        investors, potentially leading to further declines in the Company&#8217;s share
        price.&#160;&#160;It would also make it more difficult for the Company to raise
        additional capital.&#160;&#160;Further, if the Company is delisted, the Company
        would also incur additional costs under state blue sky laws in connection with
        any sales of its securities.&#160;&#160;These requirements could severely limit
        the market liquidity of the Company&#8217;s common stock and the ability of the
        Company&#8217;s stockholders to sell Cytogen common stock in the secondary
        market.</font></div>

  Item
          3.01
  Notice of Delisting
          of Failure to Satisfy a Continued Listing Rule or Standard; Transfer of
          Listing.
  On
        November 5, 2007, Cytogen Corporation (the "Company") received a Staff
        Deficiency Letter from The Nasdaq Stock Market ("Nasdaq") stating that the
        Company is not in compliance with the $1.00 minimum bid price requirement for
        continued inclusion on the Nasdaq Global Market pursuant to Marketplace Rule
        4450(a)(5).  This letter is standard when a Nasdaq listed company's
        bid price closes below the minimum $1.00 per share requirement for 30
        consecutive days.  The closing price of the Company's common stock has
        been below $1.00 per share since September 24, 2007.
  The
        Nasdaq notification has no effect on the listing of the Company's's common stock
        at this time and the Company will continue to trade on the Nasdaq Global Market
        under the symbol CYTO.   The letter states that the Company has
        180 calendar days, or until May 5, 2008, to regain compliance with the minimum
        bid price requirement of $1.00 per share.  The Company can
        achieve compliance, if at any time before May 5, 2008, Cytogen's common stock
        closes at $1.00 per share or more for at least 10 consecutive business
        days.
  If
        compliance with Nasdaq's Marketplace Rules is not achieved by May 5, 2008,
        Nasdaq will provide notice that the Company's common stock will be delisted from
        the Nasdaq Global Market.  In the event of such notification, the
        Company would have an opportunity to appeal Nasdaq's determination or to apply
        to transfer its common stock to the Nasdaq Capital Market.  If the
        Company's appeal for continued listing on the Nasdaq Global Market is not
        granted and the Company is not permitted to transfer to the Nasdaq Capital
        Market, the common stock may trade on the National Association of Securities
        Dealers' OTC Bulletin Board.
  There
        can
        be no assurance that the Company will be able to maintain the listing of its
        Common Stock on the Nasdaq Global Market.  Delisting from Nasdaq
        Global Market would make trading the Company's common stock more difficult for
        investors, potentially leading to further declines in the Company's share
        price.  It would also make it more difficult for the Company to raise
        additional capital.  Further, if the Company is delisted, the Company
        would also incur additional costs under state blue sky laws in connection with
        any sales of its securities.  These requirements could severely limit
        the market liquidity of the Company's common stock and the ability of the
        Company's stockholders to sell Cytogen common stock in the secondary
        market.
  A
        copy of
        the Company's press release announcing the Company's receipt of the notification
        from Nasdaq is attached hereto as Exhibit 99.1.
