YM BioSciences Cleared to Initiate Clinical trial of Nimotuzumab in colorectal
Cancer
MISSISSAUGA, ON, June 4 /CNW/ - YM BioSciences Inc. (AMEX:YMI, TSX:YM,
AIM:YMBA), an oncology company that identifies, develops and commercializes
differentiated products for patients worldwide, today announced that it has
received a No Objection Letter from Health Canada to initiate the planned
Phase II trial investigating nimotuzumab in colorectal cancer patients who
have failed previous irinotecan-containing regimens. Nimotuzumab is a
humanized monoclonal antibody that targets the epidermal growth factor
receptor (EGFR).
The single-arm trial will enroll approximately 100 patients in Canada who
will be treated with irinotecan plus nimotuzumab. Equal cohorts investigating
two dosing schedules will be enrolled. Recruitment of the first cohort is
expected to be completed within approximately 12 months from initiation
following which data on the primary endpoint - response rate - will be
reported.
"As colorectal cancer is the second leading cause of cancer death in
North America, this trial could generate important data for expanding the
prospective market for nimotuzumab," said David Allan, Chairman and CEO of
YM BioSciences. "Other EGFR targeting antibodies have shown efficacy and been
approved for treating this form of cancer. We are optimistic that this trial
will give preliminary evidence that our EGFR antibody has the prospect for
being as effective in response rates while providing a superior safety profile
compared to other drugs in its class, as has been consistently seen in
previous trials."
Nimotuzumab is approved for sale in India and China as well as certain
Latin American countries for the treatment of head and neck cancers. It
continues to be differentiated from the other antibodies and small molecules
targeting the tyrosine kinase pathway as treatment with the other drugs in
this class may result in the debilitating and unpleasant side-effects of
severe rash, conjunctivitis, painful paronychial inflammation, hypomagnesemia,
diarrhea and constipation. Such side-effects have rarely been reported in
patients treated with nimotuzumab.
YM BioSciences has previously announced its intention to also file for
trials with nimotuzumab in pediatric pontine glioma, and esophageal cancer
during 2007. Nimotuzumab has been sub-licensed by YM to Daiichi Sankyo Co.,
Ltd for Japan and to other companies advancing the drug in Taiwan, Indonesia,
and Korea. Oncoscience AG, the European licensee, advised YM that it expects
to complete enrollment in its Phase III trial in pediatric pontine glioma in
the coming months. YM also recently announced the receipt of a No Objection
Letter from Health Canada and a positive certificate of inspection from a
competent authority in the EU for the scaled-up manufacturing of the drug at
the Center of Molecular Immunology and also announced an expected further
doubling of manufacturing capacity at that facility during 2007.
