The name and address of the principal executive offices of the Issuer is DOR
BioPharma, Inc., 1691 Michigan Ave., Suite 435, Miami, FL 33139.

Item 2. Identity and Background.

     Item 2 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     This Schedule 13D is filed by Elan Corporation, plc, an Irish public
limited company ("Elan"), Elan International Services, Ltd., a Bermuda exempted
company ("EIS"), and Elan Pharmaceutical Investments, Ltd., a Bermuda exempted
company ("EPIL"). EPIL is a wholly owned subsidiary of EIS. EIS is a wholly

     Elan's principal place of business is Lincoln House, Lincoln Place, Dublin

laws, or finding any violation with respect to such laws

Item 3. Source and Amount of Funds or Other Consideration.

     Item 3 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     Pursuant to a securities purchase agreement dated January 21, 1998 between
EIS and the Issuer (the "First Securities Purchase Agreement"), EIS acquired (a)
307,692 shares of Common Stock, (b) 80,100 shares of Series B Convertible
Preferred Stock of the Issuer (the "Series B Preferred Stock") and (c) a warrant
to purchase up to 230,770 shares of Common Stock at an exercise price of $10.00
per share (the "Warrant") for aggregate consideration of $10,010,000, which was
provided by



                                  Page 5 of 15


working capital of EIS. The Series B Preferred Stock accrues cumulative
pay-in-kind dividends at an annual rate of 8.0%, payable annually, and, at the
option of the holder, is convertible into Common Stock at a conversion price of
$5.1078 per share (after giving effect to certain anti-dilution adjustments and
subject to further anti-dilution adjustment). As of December 31, 2003, EPIL was
entitled to 46,467 shares of Series B Convertible Preferred Stock, representing
pay-in-kind dividends from the date of issuance of the Series B Preferred Stock
and, as of February 5, 2004, at the option of the holder, the Series B
Convertible Preferred Stock, including such pay-in-kind dividends, plus accrued
and unpaid dividends was convertible into 2,497,466 shares of Common Stock. The
Series B Convertible Preferred Stock is automatically convertible upon the
earlier of (i) any time if the Common Stock is traded on the Nasdaq National
Market System or The Nasdaq SmallCap Market at a price higher than $9.75 for at
least 20 out of 30 consecutive trading days and (ii) the public offering by the
Issuer of the Common Stock at a price of at least $5.1078 (subject to
adjustment) and with aggregate gross proceeds of at least $10 million.

     Pursuant to a securities purchase agreement dated October 21, 1998 between
EIS and the Issuer (the "Second Securities Purchase Agreement"), EIS acquired
84,105 shares of Series C Exchangeable Convertible Stock of the Issuer (the
"Series C Preferred Stock") for aggregate consideration of $8,410,500. The
Series C Preferred Stock accrued cumulative pay-in-kind dividends at an annual
rate of 7.0%, payable annually.

     In June 1999, EIS transferred to EPIL its right, title and interest to its
shares of Common Stock, Series B Preferred Stock and Series C Preferred Stock
and the Warrant.

     On October 21, 2002, the Series C Preferred Stock, including shares that
were issuable as pay-in-kind dividends, was automatically converted pursuant to
its terms into 1,245,187 shares of Common Stock at a conversion price of $8.86
per share.

     On December 12, 2002, pursuant to the Newco I Termination Agreement (as
defined below), the Issuer issued 500,000 shares of Common Stock in exchange for
the Newco I Shares (as defined below).

     On January 21, 2004, the Warrant expired pursuant to its terms.

Item 4. Purpose of Transaction.

     Item 4 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     In connection with the transactions described in the first paragraph of
Item 3, the Issuer and EIS established a new joint venture company ("Newco I"),
initially owned 80.1% by the Issuer and 19.9% by EIS. Newco I was initially
capitalized with $10,000,000, of which $8,010,000 was provided by the Issuer and
$1,990,000 was provided by EIS. EIS acquired 19,900 shares of common stock of
Newco I (the "Newco Shares"). Newco I was established principally for the
exclusive research, development and commercialization of oral and mucosal
prophylactic and therapeutic vaccines. The Newco I joint venture was terminated
pursuant to a Termination Agreement dated December 12, 2002 (the "Newco I
Termination Agreement") among Elan, EIS, Orasomal Technologies, Inc., the Issuer
and Innovaccines Corporation.



                                  Page 6 of 15


     In connection with the transactions described in the second paragraph of
Item 3, the Issuer and EIS agreed to establish a new joint venture company
("Newco II"), initially owned 80.1% by the Issuer and 19.9% by EIS. Newco II was
initially capitalized with $10,500,000, of which $8,410,500,000 was provided by
the Issuer and $2,089,500 was provided by EIS. Newco II was established
principally for the exclusive research, development and commercialization of
products using Elan's Medipad(TM) delivery system for two drugs in undisclosed
fields. The Newco II joint venture was terminated pursuant to a Termination
Agreement dated March 2003 (the "Newco II Termination Agreement"), among Elan,
EIS, Elan Medical Technologies, Ltd., the Issuer and Endorex Newco, Ltd.

     The Termination Agreement amended the board of directors' provisions set
forth in the First Securities Purchase Agreement to provide that for as long as
EIS and/or its affiliates or subsidiaries (collectively, for purposes of this
paragraph, "EIS") collectively own at least 10% of the Common Stock, on a fully
diluted basis (i.e., after giving effect to the conversion, exchangeable or
exercisable securities), EIS would be entitled to nominate a director (the "EIS
Director"), and the Issuer would use its best efforts to cause the EIS Director
to be elected to the Issuer's board of directors, including by including the EIS
Director in the management slate of directors at each meeting of stockholders at
which an election of directors was to occur. At any time that EIS did not have
its own designee sitting on the Issuer's board of directors, if EIS so
requested, EIS would be entitled to appoint an observer to attend each meeting
of the Issuer's board of directors. EIS has subsequently sent a letter to the
Issuer renouncing EIS's right to nominate a director and agreeing that it would
not exercise such right.

     EPIL has a present intention to sell up to 1,552,879 shares of the Common
Stock from time to time in open market transactions, subject to market
conditions. EIS and EPIL expect to evaluate their investments in the Issuer on
an ongoing basis and EIS and EPIL may determine to change their investment
intent with respect to the Issuer at any time in the future. In determining from
time to time whether to sell or to retain their holdings of securities of the
Issuer, EIS and EPIL will take into consideration such factors as they deem
relevant, including the market price of the Common Stock, conditions in the
securities markets generally, the Issuer's financial condition, business and
prospects and general economic conditions. EIS and EPIL reserve the right to
dispose of all or a portion of their holdings of securities of the Issuer in
public or private transactions and/or to enter into privately negotiated
derivative transactions with institutional counterparties to hedge the market
risk of some or all of their positions in the securities of the Issuer. Any such
transaction may be effected at any time or from time to time.

     Except as set forth in this Item 4 or elsewhere in this Schedule 13D, none
of Elan, EIS or EPIL has a plan or proposal which relates to or would result in:

     (a)  The acquisition by any person of additional securities of the Issuer,
          or the disposition of securities of the Issuer;

     (b)  An extraordinary corporate transaction such as a merger,
          reorganization or liquidation, involving the Issuer or any of its
          subsidiaries;

     (c)  A sale or transfer of a material amount of assets of the Issuer or any
          of its subsidiaries;



                                  Page 7 of 15


     (d)  Any change in the present board of directors or management of the
          Issuer, including any plans or proposals to change the number of or
          term of directors or to fill any existing vacancies on the board;

     (e)  Any material change in the present capitalization or dividend policy
          of the Issuer;

     (f)  Any other material change in the Issuer's business or corporate
          structure;

     (g)  Changes in the Issuer's charter, bylaws or instruments corresponding
          thereto or other actions which may impede the acquisition of control
          of the Issuer by any person;

     (h)  Causing a class of securities of the Issuer to be delisted from a
          national securities exchange or cease to be authorized to be quoted in
          an inter-dealer quotation system of a registered national securities
          association;

     (i)  A class of equity securities of the Issuer becoming eligible for
          termination of registration pursuant to Section 12(g)(4) of the Act;
          or

     (j)  Any action similar to any of those enumerated above.

Item 5. Interest in Securities of Issuer.

     Item 5 of the Schedule 13D is hereby amended and restated in its entirety
as follows:
