This Amendment No. 7 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 11
------------------------


                  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 807,040 shares of Common Stock of the
Issuer or approximately 6.2% 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 herein by reference to Exhibit No. 10.8 to Registration
         Statement No. 333-4441 on Form S-1).

 2.      Letter Agreement dated March 23, 1999 between the Issuer and the
         Company (incorporated herein by reference to Exhibit No. 2 to Amendment
         No. 2 to this Schedule 13D).
