MethylGene and Pharmion Announce Orphan Drug Designation Granted by the European Medicines Agency (EMEA) for MGCD0103 for the Treatment of Hodgkin's Lymphoma

- Follows the Companies' Previous Announcement of MGCD0103's Orphan Drug Designation for the Treatment of Hodgkin's Lymphoma in the United States -

MONTREAL, QUEBEC AND BOULDER COLORADO--(Marketwire - Sept. 24, 2007) - MethylGene, Inc. (TSX:MYG) and Pharmion (NASDAQ:PHRM) today announced that the European Medicines Agency (EMEA) and the European Commission (EC) designated MGCD0103, a histone deacetylase (HDAC) inhibitor, as an Orphan Medicinal Product for the treatment of Hodgkin's lymphoma in the European Union (EU). Criteria for designation require that the product be intended for the treatment of life-threatening or serious conditions that are rare and affect not more than five in 10,000 persons in the EU.

Preliminary data from a MGCD0103 Phase II monotherapy clinical trial in relapsed and refractory Hodgkin's lymphoma were presented at the American Society of Clinical Oncology 2007 Annual Meeting in June and were included in the application for orphan drug designation. The data demonstrated an objective complete response (CR) plus partial response (PR) rate of 40 percent and a disease control rate (CR + PR + stable disease for greater than 6 cycles) of 45 percent in a population of 20 evaluable patients that had relapsed disease or were refractory (unresponsive) to all previous treatments, including, in most cases, bone marrow transplantation. Fatigue and gastrointestinal side effects were the most common adverse events and dose modification was effective in many of these patients.

Orphan Medicinal Product Designation allows special incentives for sponsors planning to test a product for use in a rare disease or condition generally characterized by a small number of patients. These incentives include eligibility for protocol assistance and possible exemptions or reductions of certain regulatory fees during development or at the time of application for marketing approval. Once approved, the product may qualify for 10 years of marketing exclusivity in the EU.

MGCD0103 is an orally-administered, isotype-selective HDAC inhibitor. The compound is currently in two Phase I/II clinical trials in combination with Vidaza® for hematological malignances and with Gemzar® in solid tumors and in four Phase II monotherapy clinical trials in hematological malignancies.

About Hodgkin's Lymphoma

Hodgkin's lymphoma (HL) is a cancer of the lymphatic system that begins in the lymph nodes and progresses to other organs, including the lungs, liver, bone and bone marrow. It is characterized by the presence of Reed-Sternberg cells. Currently, there is no known cause of the disease, but epigenetic alterations including histone acetylation, have been identified. In addition, the Epstein-Barr virus, HIV and familial history are known risk factors. The disease is slightly more prevalent in men than women, and the median age of diagnosis is 38.
