          ---------                                                     ---   --

This Amendment No. 6 is being filed to amend Item 5 of this Schedule 13D.

Item 1.  SECURITY AND ISSUER.

      The class of equity securities to which this Statement relates is the
Common Stock, par value $0.01 per share (the "COMMON STOCK"), of Cadus
Pharmaceutical Corporation, a Delaware corporation (the "ISSUER"), which has its
principal executive offices at 767 Fifth Avenue, New York, NY 10153.

Item 2.  IDENTITY AND BACKGROUND.

      This Amendment is being filed by Bristol-Myers Squibb Company, a Delaware
corporation (the "COMPANY"). The Company conducts its principal business and
maintains its principal office at 345 Park Avenue, New York, NY 10154. The
Company is a worldwide pharmaceutical and related health care products company.

      The name, business address, present principal occupation or employment and
citizenship of each executive officer and director of the Company is set forth
on SCHEDULE A which is incorporated herein by reference.

      During the past five years, neither the Company nor, to the best knowledge
of the Company, any of its executive officers or directors (i) has been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) was a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and, as a result of such
proceeding, was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation with respect to such laws.

Item 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      In July 1994, the Issuer and the Company entered into a research
collaboration, whereby the Company agreed to make an initial equity investment
of $12,500,000 in the Issuer's Series B Preferred Stock. The Company made an
additional equity investment of $5,000,000 in the Issuer's Series B Preferred
Stock in September 1995 upon the Issuer achieving a research milestone. Both
equity investments came out of the working capital of the Company.





CUSIP No. 127639102                  SCHEDULE 13D                   Page 4 of 12
          ---------                                                     ---   --


      On July 17, 1996, the Issuer completed an initial public offering of its
Common Stock with a per share offering price of $7.00. The Company made an
additional equity investment of $2,500,000, acquiring 355,000 shares of Common
Stock. The purchase price for this investment came out of the working capital of
the Company.

Item 4.  PURPOSE OF TRANSACTION.

      The Company acquired the Common Stock of the Issuer for the purpose of
making an investment in the Issuer and not with the view to, or for resale in
connection with, any distribution thereof. The Common Stock of the Issuer was
initially acquired in connection with a research collaboration between the
Company and the Issuer which expired in July 1999.

      The Company and the Issuer are parties to a letter agreement (the "LETTER
AGREEMENT") concerning the Company's shares of the Common Stock. Such Letter
Agreement is filed as an exhibit hereto and is incorporated herein by reference.
The Letter Agreement includes certain notice requirements and transfer
restrictions with respect to the Company's shares of the Common Stock. Subject
to market conditions and the Letter Agreement, the Company may, in its sole
discretion, sell all or a portion of its shares of Common Stock from time to
time in open market transactions or otherwise.

Item 5.  INTEREST IN SECURITIES OF THE ISSUER.

      To the best knowledge of the Company, as of December 31, 2002, the Company
is the beneficial owner of 941,500 shares of Common Stock of the Issuer or
approximately 7.2% of the Common Stock of the Issuer currently outstanding. The
Company has the sole power to vote and dispose of all the shares of the Common
Stock of the Issuer that it owns.

      Except as set forth in this Item 5 and on SCHEDULE B attached hereto which
is incorporated herein by reference, neither the Company nor, to the best
knowledge of the Company, any of its officers or directors owns any shares of
Common Stock.

      Except as set forth in Item 3 and on SCHEDULE B attached hereto which is
incorporated herein by reference, neither the Company nor, to the best knowledge
of the Company, any of its executive officers or directors has effected any
transaction in shares of Common Stock during the past sixty (60) days.

Item 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDING OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

      The Preferred Stock Purchase Agreement, together with First Amendment
thereto, filed as an exhibit hereto is incorporated herein by reference. Except
as set forth in such Agreement or the Letter Agreement, neither the Company nor,
to the best knowledge of the Company, any of its officers or directors have
entered into any contracts, arrangements, understandings or relationships (legal
or otherwise) with respect to the Common Stock of the Issuer.

Item 7.  MATERIAL TO BE FILED AS EXHIBITS.

1.    Preferred Stock Purchase Agreement dated as of July 26, 1994 between
      Issuer and the Company concerning Series B Preferred Stock, together with
      the First Amendment thereto dated as of October 31, 1995 (incorporated

      333-4441 on Form S-1).

      this Schedule 13D).
