Biotechnology company MabCure, Inc. (OTCBB: MBCI) is presenting
the results of its recently completed study on the diagnosis of
ovarian cancer utilizing its proprietary monoclonal antibodies at
the annual meeting of the Society of Gynecological Oncologists
(SGO).
The 2011 Annual SGO meeting on Women's Cancer currently underway
in Orlando, Florida, will be the first time MabCure has shared its
peer reviewed data from a July 2010 study. The study results
provide initial clinical proof of concept that MabCure’s ovarian
cancer antibodies are capable of distinguishing between ovarian
cancer and benign tumors of the ovary with 100% specificity, i.e.
no false positives.
MabCure conducted the blinded study of several of its ovarian
cancer monoclonal antibodies (MAbs) against 54 different blood
samples, in collaboration with Professor Vergote of the Department
of Gynecological Oncology at UZ Hospital in Leuven, Belgium. The
samples were comprised of 17 patients with ovarian cancer, 5
patients with benign tumors of the ovaries, 24 healthy young
females and 8 males. Results showed that three of MabCure’s MAbs
correctly identified 16 of the 17 ovarian cancers, with a
diagnostic sensitivity of 94 percent and 100 percent correct
classification of the benign tumors.
MabCure’s proprietary technology is based on re-engineered
hybridoma methodology, designed to achieve significant quantitative
and qualitative improvements. As such, MabCure is capable of
generating more than 10,000 hybridomas over the course of 4-6 weeks
compared to classic hybridoma which generates 500-2,000 hybridomas
over a period of 4-6 months. Furthermore, MabCure’s proprietary
technology preserves the three-dimensional structure of the surface
antigens on the cancer cells. This allows the immune system to
generate highly specific antibodies against the native antigens
(i.e. markers) on the cancer cell. The combination of highly
specific antibodies coupled with large output, i.e. large library
containing more than 30,000 hybridomas, provides MabCure with the
ability to select only a handful of the most highly specific
monoclonal antibodies against unique tumor specific antigens (TSA)
appearing on targeted cancer cells.
A key feature in MabCure’s antibodies is that they are directed
against TSA which are uniquely expressed on cancer cells but not on
normal cells. These are distinct from most therapeutic or
diagnostic antibodies which target normal antigens that are
over-expressed in subsets of patients having certain cancers.
MabCure’s Chief Scientific Officer, Dr. Charles Tackney, who is
presenting MabCure’s results at the SGO meeting, stated that “there
is a critical need for new diagnostic tools which would allow
physicians to quickly and reliably determine a patient’s disease
status. MabCure’s results are at a pivotal phase in that process.
There is much interest from physicians and researchers alike in the
current study, as well as seeing the results of our larger study in
progress and the determination of the cellular targets identified
by MabCure’s antibodies. Confirmation of initial results and the
deployment of a robust and validated immunoassay are an active and
exciting part of the conversation at SGO. Our data has certainly
generated much interest and promises to deliver on a much needed
new medical diagnostic tool for oncologists.”
MabCure intends to expand on this study with a follow-on study
of more than 100 blood samples containing ovarian cancer and benign
tumors of the ovaries, in collaboration with the Catholic
University Hospital, Leuven, Belgium. Both the samples from this
study as well as samples from the Company’s clinical study in
Thailand are expected to be analyzed concurrently, using highly
purified MAbs, during the second quarter of 2011.
About MabCure Inc.
MabCure is a biotechnology company whose vision is to change the
perception of cancer as being a largely incurable disease. MabCure
owns proprietary technology for the creation of unique and highly
specific monoclonal antibodies (MAbs), which we plan to develop as
diagnostic tools, imaging agents, and drugs to treat lethal
cancers. MabCure’s initial goal is to develop its novel MAbs as
diagnostic tools for the detection of ovarian and prostate cancers
at an early stage, when these diseases are still localized and
highly curable. For further information visit the Company’s website
