MG-98

Montreal, Quebec. December 15, 2006 – MethylGene Inc. (TSX: MYG) today announced that based on recent R&D successes in its small molecule oncology programs and a strategic review of its cancer pipeline, it will not pursue additional clinical trials for MG98, its second generation antisense compound targeting DNA methyltransferase. This decision is made with its North American co-development partner for the compound, MGI PHARMA, INC. The companies have agreed to seek alternative development partners or arrangements for the MG98 program. MethylGene will continue to focus its clinical development investment in more commercially attractive alternatives such as MGCD0103, its oral isotype-selective histone deacetylase (HDAC) inhibitor which is currently in Phase II monotherapy and Phase I/II combination trials; and MGCD265, its recently selected oral, multi-targeted kinase (c-MET) clinical candidate. The company will also continue to concentrate its efforts in other HDAC programs including MG3290, an HDAC inhibitor to overcome antifungal resistance to azoles, and HDAC inhibitors for Huntington’s disease for which clinical candidates and potential Investigational New Drug (IND) applications are expected in 2007. “We believe this decision along with the positive data recently disclosed at ASH for MGCD0103 and the selection of our multi-targeted kinase (c-MET) clinical candidate will enhance shareholder value as we build upon the positive momentum achieved to date.” commented Donald F. Corcoran, President and Chief Executive Officer, MethylGene. “While we are encouraged by the positive data reported on MG98 at ASCO in June, prioritization of our pipeline is key to success and it is important to allocate resources to the most promising and commercially attractive compounds and activities. We hope to attract new partners or arrangements for MG98, where the compound will be a priority and may advance based on its own merits.” By not initiating additional MG98 clinical trials, approximately $3 million will be reallocated to these other programs in 2007 and 2008 and the company will still maintain its forecast of sufficient cash resources into the fourth quarter of 2008. No significant financial contribution from MGI PHARMA, INC. was expected over this period.
