Clinical Data On Pharmion Corporation's Marketed And Pipeline Products To Be Presented At The American Society of Clinical Oncology 42nd Annual Meeting

BOULDER, Colo., June 1 /PRNewswire-FirstCall/ -- Pharmion Corporation reported today that data from 26 abstracts from studies investigating the company's marketed and pipeline products will be presented at the American Society of Clinical Oncology (ASCO) 42nd Annual Meeting in Atlanta (June 2-6, 2006). These abstracts, one of which will be the topic of a 2006 ASCO meeting plenary session, include summaries of data from several studies evaluating the benefits of thalidomide in newly-diagnosed multiple myeloma.

Pharmion licenses commercialization rights for thalidomide in Europe and additional international markets and shares joint development responsibility for the drug. Data from a first-line study supported by Pharmion will be the subject of an ASCO plenary session. Thalidomide data accepted for presentation at the 2006 ASCO meeting will highlight the effects of this compound in combination with other approved therapies for use in newly-diagnosed multiple myeloma.

Pharmion currently markets Vidaza(R) (azacitidine for injectable suspension) in the U.S. The drug was approved in May 2004 for the treatment of all five sub-types of Myelodysplastic Syndromes (MDS). Abstracts presented at this year's ASCO meeting will report data from studies investigating the use of Vidaza in a variety of combination therapies for the treatment of MDS, secondary MDS, AML, advanced cancers and ovarian cancer. Additionally, accepted abstracts will address the effects of alternate dosing regimens of Vidaza in patients with MDS, as well as blood transfusion independence associated with Vidaza.

In January of this year, Pharmion entered a licensing and collaboration agreement for MethylGene, Inc.'s histone deacetylase (HDAC) inhibitors in North America, Europe, Middle East and certain other markets. This collaboration includes MethylGene's lead oncology HDAC inhibitor, MGCD0103, as well as the company's pipeline of second-generation HDAC inhibitor compounds for oncology indications. Two oral presentations on studies of MCGD0103 in advanced solid tumors and leukemia and MDS will be presented during ASCO.

Satraplatin, the oral platinum compound for which Pharmion licensed the commercial rights in Europe and certain international markets from GPC Biotech AG in December 2005, will be the subject of two abstracts at the conference. Pharmion maintains a co-development agreement with GPC Biotech for satraplatin.

The following clinical data will be presented during the ASCO 2006 annual meeting:
