            This Amendment No. 1 to Schedule 13D (this "Amendment") is filed by
the undersigned to amend the Statement on Schedule 13D, filed by the undersigned
on October 24, 2005 (the "Original Filing"). Unless otherwise indicated, all
capitalized terms shall have the same meaning as provided in the Original
Filing. Any reference to "this Schedule 13D" in the Original Filing or in this
Amendment shall refer to the Original Filing as amended by this Amendment.

ITEM 1. SECURITY AND ISSUER

         The title and class of equity securities to which this statement on
Schedule D relates is American Depositary Shares ("ADS"), each representing one
ordinary share of Gentium SpA (the "Issuer"). The ADSs have been issued pursuant
to a Deposit Agreement dated as of June 15, 2005, among the Issuer, the Bank of
New York, as Depositary, and the owners from time to time of ADSs issued
thereunder.

         The name and address of the principal executive offices of the Issuer
is Gentium SpA, Piazze XX Septembre 2, 22079 ViVa Guardia, Como Italy.

ITEM 2. IDENTITY AND BACKGROUND

         Item 2 is hereby amended to change the address of Biomedical Value
Fund, L.P. ("BMVF"), Great Point Partners LLC ("Great Point"), and Dr. Jeffrey
R. Jay ("Dr. Jay"), from 2 Pickwick Plaza, Suite 450, Greenwich, CT, 06830 (as
originally filed on October 24, 2005), to the current principal office at 165
Mason Street, 3rd Floor, Greenwich, CT, 06830.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION


         Not applicable.



ITEM 4. PURPOSE OF TRANSACTION

         Between June 13th and 15th, 2007, each of BMVF and BOVF sold all of the
ADSs owned by them. See Item 5 for continuing beneficial ownership.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

         Item 5 is hereby amended and restated as follows:

         (a) through (b)

         BMVF owns warrants to purchase 212,766 ADSs. Such securities, in the
aggregate, constitute 1.46% percent of the outstanding share capital of the
Issuer, computed in accordance with Rule 13d-3. BMVF shares dispositive power
over the warrants to purchase ADSs owned by it and, in the event of the exercise
of such warrants, would share voting power with respect to the ADSs for which
such warrants are exerciseable. BMVF disclaims beneficial ownership of any
securities owned by BOVF. See Item 2.


                                       6



          BOVF owns warrants to purchase 212,766 ADSs. Such securities, in the
aggregate, constitute 1.46% percent of the outstanding share capital of the
Issuer, computed in accordance with Rule 13d-3. BOVF shares dispositive power
over the warrants to purchase ADSs owned by it and, in the event of the exercise
of such warrants, would share voting power with respect to the ADSs for which
such warrants are exerciseable. BOVF disclaims beneficial ownership of any
securities owned by BMVF. See Item 2.

          The warrants to purchase ADSs will be issued only if the issuance
thereof, including the ordinary shares of the Issuer underlying the ADSs, are
authorized at a shareholders' meeting of the Issuer.

          Great Point is the investment manager of each of BMVF and BOVF, and by
virtue of such status has shared voting and investment power with respect to
securities owned and held by BMVF and BOVF and may be deemed to be the
beneficial owner of such securities. Dr. Jay, as senior managing member of Great
Point, has shared voting and investment power with respect to securities owned
and held by BMVF and BOVF and may be deemed to be the beneficial owner of such
securities. Great Point and Dr. Jay disclaim beneficial ownership of the shares
of Common stock held by BMVF and BOVF, except to the extent of any pecuniary
interest, and this Schedule 13D shall not be deemed to be an admission that they
are the beneficial owners of such securities.

         (c) From the period between June 13, 2007 and June 15, 2007 BMVF sold
531,915 ADSs held by it and BOVF sold 531,915 ADSs held by it.

         (d) Not applicable.

         (e)  Each  of  the  persons  referred  to in  Item 2  ceased  to be the
beneficial  owner of more than five  percent of any class of  securities  of the
Issuer on June 15, 2007.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER

         Not applicable.


                                       7

            the Schedule 13D dated as of October 24, 2005, and incorporated
            herein by reference).
