MethylGene Presents MGCD265 Data at the 24th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics


MONTREAL, CANADA--(Marketwire - Nov 8, 2012) - MethylGene Inc. (MYG.TO) today announced that data for the clinical-stage Met/VEGFR inhibitor MGCD265, was presented at the 24th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics, in Dublin, Ireland.

In the poster entitled "A Novel Assay for the Met Inhibitory Activity of MGCD265 in Plasma From Solid Tumor Patients in a Dose Escalating Phase I Study" data was presented using an ex vivo assay, in which plasma samples from patients treated with MGCD265 were tested for the ability to inhibit Met phosphorylation in a human cancer cell line. In the ongoing clinical trials, patient plasma levels have been reached that result in ~80% inhibition of Met phosphorylation. In companion studies using a human tumor xenograft model, Met inhibitory activity in mouse plasma correlated with inhibition of Met phosphorylation in the tumor as well as dose-dependent inhibition of tumor growth.

"It is encouraging that the MGCD265 exposures in patients and the accompanying level of Met inhibition are in the range at which tumor growth inhibition is observed in animal models." said Dr. Jeffrey Besterman, Chief Scientific Officer of MethylGene.

About MGCD265

MGCD265, a rationally designed, orally administered small molecule kinase inhibitor designed to target Met and the VEGFR 1,2, and 3 receptor tyrosine kinases (RTKs). RTKs, including Met, are key kinases involved in cancer, angiogenesis (a process whereby new blood vessels are formed to nourish the tumors), tumor cell metastasis, tumor development and survival. Met expression is elevated and associated with tumorigenesis in several solid tumor indications including NSCLC, gastric, prostate, colorectal, bladder, breast and ovarian cancers. Phase I/II studies of single agent MGCD265 and combinations with erlotinib or docetaxel are currently underway.

More than 200 patients have been treated to date in clinical studies of both single-agent and combination therapy with docetaxel or erlotinib. In combination trials, six of 104 patients have been on study for over one year at a variety of doses: NSCLC (n=2), GE cancer (n=2), ovarian cancer (n=1) and chordoma (n=1). Additionally, disease control in the combination study was observed in 11/12 NSCLC patients (with two partial responses) and 4/9 patients with GE cancer (2 non-complete response/non-progressive disease). MGCD265 continues to demonstrate a favorable safety profile. Drug-related diarrhea, fatigue and lipase elevation have been observed in patients receiving MGCD265 monotherapy The maximum tolerated dose has not yet been defined and dose escalation continues.
