sor genes, thereby promoting tumor growth. MGCD0103 is an
orally-administered, selective HDAC inhibitor, which targets
specific class I HDAC isotypes. Preclinical data suggest that these
HDAC isotypes are important in cancer biology and, consequently,
such selective HDAC inhibitors may have increased efficacy and
reduced toxicity compared to non-selective inhibitors.
Myelodysplastic Syndrome (MDS) and Acute Myelogenous Leukemia
(AML) (Trial 005)
Data presented in a poster session by Guillermo Garcia-Manero,
M.D., principal investigator, Associate Professor of Medicine and
Chief, Section of Myelodysplastic Syndromes, Department of
Leukemia, M.D. Anderson Cancer Centre, demonstrated that
combination treatment with MGCD0103 and Vidaza(r) (azacitidine for
injection) resulted in a 30 percent response rate for all patients,
and a 37 percent response rate in the active dose ranges previously
reported. Of the 37 patients in this trial, eleven patients (two
MDS patients and nine AML patients) experienced objective clinical
responses. In addition, the combination therapy showed good
pharmacodynamic properties and acceptable safety in these
patients.
"MGCD0103 and Vidaza are two epigenetic agents that have
demonstrated single-agent activity in AML and MDS," said Dr.
Garcia-Manero. "In this study we found that these agents can be
given together, and that the resulting clinical activity is better
than expected from each agent alone."
"We are very encouraged by the single-agent activity to date in
our Hodgkin's lymphoma trial. These patients have progressive
disease after receiving multiple prior therapies and there are
currently no approved alternative treatments available to them,"
said Donald F. Corcoran, President and Chief Executive Officer of
MethylGene. "In addition, the responses in our Vidaza-MGCD0103
combination trial are consistent with our earlier data. The data
from these two ongoing trials have given us potential direction for
registratio
