MethylGene Reports Third Quarter 2010 Financial Results and Provides Clinical Update for MGCD265

MONTREAL, QUEBEC--(Marketwire - November 12, 2010) - MethylGene Inc. (TSX: MYG) today announced financial results for the third quarter ended September 30, 2010. In addition, the Company provided a clinical trial update for its multi-targeted (Met) kinase oncology inhibitor, MGCD265.

Financial Results Reported in Canadian Dollars

Total revenues for the third quarter ended September 30, 2010 were $587,000 compared to $485,000 for the same period last year due to increased collaboration revenue from Otsuka.

Gross research and development expenditures in the third quarter of 2010 were $3.0 million, down 34 percent, compared to $4.6 million in the third quarter of 2009. This decrease is due to lower research and development expenses for MGCD265 and MGCD290. General and administrative expenses in the third quarter of 2010 were $2.7 million, an increase of $1.5 million compared to the third quarter of 2009 as we recorded a $1.5 million expense in relation to the departure of the previous President and Chief Executive Officer. MethylGene incurred a foreign exchange loss of $26,000 in the third quarter of 2010 versus a loss of $188,000 in the third quarter of 2009. The lower loss is the result of lower average U.S. denominated assets and a higher average exchange rate for the Canadian dollar versus the U.S. dollar. The net loss for the third quarter ended September 30, 2010 was $4.8 million or ($0.12) per share compared to a net loss of $5.4 million or ($0.15) per share for the corresponding period last year, reflecting lower operating expenses due to continued cost control efforts.

As of September 30, 2010, the Company had $10.6 million of cash, cash equivalents, and restricted cash. Based on current assumptions, the Company believes that its current cash, cash equivalents, interest income, projected revenues from current collaborations, projected timing of clinical trials and refundable investment tax credits should be sufficient to carry out its planned research and development plans and operations to the end of the first quarter of 2011. Management is actively pursuing various alternatives.

MGCD265 Update

Over 120 patients have been enrolled in three ongoing MGCD265 Phase 1 and Phase 1/2 clinical trials. The compound has been well tolerated and has demonstrated preliminary clinical activity as a single agent and in combination with docetaxel and erlotinib.

In the Phase 1/2 docetaxel-arm of Trial 265-103 (MGCD265 in combination with full-dose docetaxel), the maximum-tolerated dose (MTD) has been reached and the Company is defining the recommended Phase 2 dose. Five patients have been on the study for more than four months. Of these, four non-small cell lung cancer (NSCLC) patients have experienced stable disease for durations ranging from 8 to 13 months. One NSCLC patient achieved a confirmed partial response and the other three patients all had tumor shrinkage accompanying their stable disease. These results exceed the expectation for docetaxel alone. In the erlotinib-arm of Trial 265-103 (MGCD265 in combination with full-dose erlotinib), dose escalation continues and MethylGene believes that it is close to reaching the MTD. Twelve patients have been on study for more than four months. Of these, there is one gastric cancer patient who is currently experiencing stable disease for 11 months. The most frequent MGCD265-related toxicities in both arms of Trial 265-103 are fatigue and diarrhea, consistent with Trials 265-101 and 265-102.

In monotherapy Trial 265-101, seven patients have been on study for more than four cycles. Dose escalation is continuing in order to determine the MTD. In monotherapy Trial 265-102, the MTD has been reached and the recommended Phase 2 dose is being confirmed. Ten patients have been on study for more than four cycles, including a papillary renal cell carcinoma patient and sarcomatoid bladder cancer patient with extended stable disease durations of approximately one year. In both Trials 265-101 and 265-102, MGCD265 is well tolerated with fatigue, diarrhea and elevated lipase the most common toxicities.
