Item 1.01      Entry into a Material Definitive Agreement.

                    On December 19, 2005, Pharmion GmbH, a limited liability
               company registered in Switzerland ("Pharmion GmbH") and a
               wholly-owned indirect subsidiary of Pharmion Corporation, a
               Delaware corporation (the "Company"), and GPC Biotech AG ("GPC
               Biotech"), entered into a Co-Development and License Agreement
               and a Supply Agreement.

               The Co-Development and License Agreement ("CDLA"):
               --------------------------------------------------

                    Pursuant to the CDLA, Pharmion GmbH acquired exclusive
               commercialization rights, including the right to develop, market
               and distribute, that certain platinum complex,
               af-bis(acetato)-b-ammine-cd-dichloro-e-(cyclohexylamine)platinum
               (IV), known commercially as satraplatin, in Europe, Turkey, the
               Middle East, Australia and New Zealand.

                    Pharmion GmbH will provide an upfront payment to GPC Biotech
               of $37.1 million, which includes an $18 million reimbursement for
               past satraplatin clinical development costs and a $19.1 million
               payment for the funding of certain clinical development
               activities to be conducted jointly by Pharmion GmbH and GPC
               Biotech. The parties will form a joint development committee to
               coordinate, evaluate and expedite global development activities
               for satraplatin in a variety of tumor types. The parties will
               share costs incurred in connection with global development
               activities conducted under a development plan agreed to by the
               parties, toward which Pharmion GmbH has made an additional
               commitment of approximately $22.2 million. In addition, Pharmion
               GmbH will pay GPC Biotech $30.5 million upon the achievement of
               initial regulatory filing and approval milestones, and $15
               million for each subsequent regulatory approval for certain
               additional indications up to a maximum of $75 million for such
               approvals.

                    GPC Biotech will also receive royalties on sales of
               satraplatin by Pharmion GmbH in its territories at rates of 26 to
               30 percent on annual sales up to $500 million, and 34 percent on
               annual sales over $500 million. Finally, Pharmion GmbH is
               obligated to pay GPC Biotech up to $105 million for achievement
               of significant annual sales milestones in the Pharmion GmbH
               territories. Pharmion GmbH and GPC Biotech will each lead
               regulatory and commercial activities relating to the promotion
               and sale of satraplatin in their respective territories.

                    During the term of the CDLA, the Company has agreed to
               maintain the financial viability of Pharmion GmbH, such that
               Pharmion GmbH


                                      -2-



               will have sufficient funds available to satisfy its monetary
               obligations under the CDLA.

                    The CDLA terminates on a country by country basis on the
               last to occur of: (a) the date that sales of a generic product
               containing satraplatin by one or more third parties in a country
               in any six-month period exceed, on a per unit basis, a specified
               threshold amount of the entire market for products containing
               satraplatin in such country; (b) the last day of the defined
               royalty term in the GPC Biotech and Spectrum Pharmaceuticals,
               Inc. Co-Development and License Agreement, dated September 30,
               2002, a redacted copy of which is on file with the United States
               Securities and Exchange Commission, as Exhibit 10.1 to GPC
               Biotech's Form F-1, dated June 9, 2004; (c) the expiration date
               in such country of the last to expire of any GPC Biotech patent
               or patent held jointly between the parties to the CDLA that
               includes at least one valid claim that would be infringed by the
               sale of satraplatin; and (d) expiration of any period of data,
               market or other regulatory exclusivity available in the Pharmion
               GmbH territory. Upon termination, Pharmion GmbH retains a
               non-exclusive, fully-paid, royalty-free license to continue the
               commercialization of satraplatin in the Pharmion GmbH territory.

               The Supply Agreement:
               ---------------------

                    Pursuant to the terms of the Supply Agreement, Pharmion GmbH
               has agreed to purchase 100 percent of its requirements for
               satraplatin from GPC Biotech, and GPC Biotech has agreed to
               manufacture and supply the requirements of Pharmion GmbH for, and
               maintain certain inventories of, satraplatin. Pricing is based
               upon 110 percent of the fully allocated cost of manufacture,
               subject to annual adjustment.

                    The parties will form a joint manufacturing committee to,
               among other things, oversee activities with respect to the
               manufacture of satraplatin, to coordinate regulatory activities
               relating to its manufacture and to establish work plans for
               analytical methods transfer.
