A duo that’s sweet on new biomarkers
June 2012
SHARING OPTIONS:
PINE BROOK, N.J.—Intending to focus on urological cancers,
Ezose Sciences Inc.—an affiliate of the Diagnostics Division of Osaka,
Japan-based Shionogi & Co. Ltd.—is teaming up with another player in Japan,
Hirosaki University, to identify new biomarkers for use in predicting and
monitoring the progression of various cancers, notably those of the prostate.
Using Ezose’s GlycanMap platform, the research will examine
serum and urine samples collected by Hirosaki University clinical investigators
from well-characterized patient and control populations in Japan, to then be
analyzed by Ezose at its U.S. laboratories.
“This agreement marks another step that scientists at Ezose
and in universities are taking together to improve our understanding of the
role of glycans in health and disease,” said Dr. Hidehisa Asada, vice president
of research and development at Ezose, in the news release about the
collaboration. “Given the already established clinical utility of glycan-based
biomarkers in certain cancers, we believe that further studies in oncology hold
promise for identifying other novel biomarkers that could help guide clinical
practice.”
The short-term strategic goals of the collaboration, Asada
tells ddn, are to identify novel and
clinically useful glycan biomarkers for prostate cancer progression and
generate intellectual property rights. Under terms of the agreement, Ezose is
granted exclusive rights by Hirosaki University to develop and commercialize
new biomarkers resulting from the collaboration.
“By exercising or licensing IP rights, we would ultimately
commercialize new biomarkers to help guide drug development and clinical
practice,” he says, adding that the long-term goals are to expand research to
other types of cancers “to understand which glycans play an important role in
disease development and progression. This may also create opportunities to
identify new drug targets for attacking disease.”
The market favors an approach like this because “glycomics
[the study of sugar chains that, through glycosylation, become attached to many
proteins expressed by human cells] is beginning to come into its own as a basic
tool in biomedical research,” says Dr. Chikara Ohyama, chairman of the
Department of Urology at the Hirosaki University Graduate School of Medicine on
the university’s campus in Hon-cho. “We look forward to applying this new
technology to unmet medical needs in managing urologic cancers through the
complementary contributions of Ezose’s scientists and our own.”
Ezose and Hirosaki maintain that glycomics is a natural
complement to genomics and proteomics, but note it has traditionally been
hindered by the lack of practical high-throughput and quantitative
technologies. Ezose’s GlycanMap platform is intended to addresses this need by
combining, in an automated 96-well format, high-throughput glycan enrichment
with specialized MALDI-TOF mass spectrometry and custom bioinformatics to both
structurally identify and quantitate glycans present in complex biological
samples.
Asada says talks about the collaboration started when Ohyama
visited the Ezose company booth at the annual conference of the Society for
Glycobiology in 2009, which was just after Ezose had begun operations as a
start-up, and Ohyama’s strong leadership and publications in glycobiology
research related to urology proved to be attractive to Ezose. For Ohyama, Asada
says, the attraction was Ezose’s unique high-throughput capabilities in glycan
analysis.
“We have complementary skill sets to drive potential
products based on glycan biomarkers from bench to bedside,” Asada says.
“Hirosaki University has state-of-the-art facilities and trained leaders in
clinical urology who can facilitate quick enrollment and collection of clinical
samples for collaborative biomarker research. Also, Prof. Ohyama’s glycobiology
expertise offers opportunity for collaborative interpretation of the glycan
changes observed in cancer development and progression. Ezose Sciences brings
to the collaboration its proprietary GlycanMap analysis platform. This
technology facilitates, in a way generally not possible before, the
high-throughput identification and quantitation of glycans in clinical samples.
In addition, Ezose’s sophisticated bioinformatic tools for data readout and
visualization allow the collaborators to more broadly review and interpret
glycan data.”
Urologic cancers, such as those of the bladder and prostate,
are highly prevalent worldwide, and significant unmet needs remain for both the
medical management and treatment of these diseases, Asada points out.
“Prof. Ohyama and the team at Hirosaki are world leaders in
researching these diseases, and one of the few groups focused on glycobiology
as a new area of promising study,” he tells ddn. “Yet they, like others working in glycobiology, have been limited by
the lack of suitable high-throughput analytic methods to more rapidly progress
their work. Together, we believe that we can much more rapidly progress studies
to advance our understanding of these diseases and improve medical management and
treatment for patients.”
Ezose Sciences and Sigma-Tau advance projects in
glycomics
PINE BROOK, N.J.—In April, Ezose Sciences Inc. also
announced an agreement to apply its glycomics capabilities to biologics
research and development projects at Sigma-Tau Industrie Farmaceutiche Riunite
SPA, an Italian pharmaceutical group that specializes in immuno-oncology,
biotechnology and rare, neglected and/or high social-impact diseases.
The collaboration will build on R&D work conducted under
prior agreements between Ezose and Sigma-Tau. Financial terms and other details
were not disclosed.
Marco Brughera, corporate R&D managing director of
Sigma-Tau, said in a statement, “As a company committed to innovation, we rely
not only on the contributions of Sigma-Tau’s in-house scientific talent, but
also on the support of others who are pioneering their special fields. We
welcome this opportunity to work with Ezose in bringing their unique glycomics
capabilities to our research program.” Code: E061207 Back |
