BETHESDA,
Md., Sept. 13 /PRNewswire/ -- The National Cancer
Institute (NCI) have announced at a media briefing
a new $144.3 million, five-year initiative to develop
and apply nanotechnology to cancer. Nanotechnology,
the development and engineering of devices so small
that they are measured on a molecular scale, has already
demonstrated promising results in cancer research
and treatment.
"Nanotechnology has the potential to radically
increase our options for prevention, diagnosis, and
treatment of cancer," said Andrew von Eschenbach,
M.D., director of the National Cancer Institute. "NCI's
commitment to this cancer initiative comes at a critical
time. Nanotechnology supports and expands the scientific
advances in genomics and proteomics and builds on
our understanding of the molecular underpinnings of
cancer. These are the pillars which will support progress
in cancer."
To carry out this initiative, the NCI, part of the
National Institutes of Health, is forming the NCI
Alliance for Nanotechnology in Cancer, a comprehensive,
integrated initiative encompassing researchers, clinicians,
and public and private organizations that have joined
forces to develop and translate cancer-related nanotechnology
research into clinical practice.
"The Alliance lays out a process to safely accelerate
the application of nanotechnology to cancer research,"
said NCI Deputy Director Anna Barker, Ph.D. "Central
to this initiative will be multidisciplinary partnerships
involving physicists, biologists, clinicians, engineers,
and other experts that can translate knowledge on
cancer and nanotechnology into clinically useful products."
The new NCI Alliance for Nanotechnology in Cancer
is one of the first steps in implementing the Cancer
Nanotechnology Plan, which was developed over the
past 18 months with the input of a broad cross-section
of the cancer research and clinical oncology communities.
The NCI Alliance consists of four major program activities:
* Centers of Cancer Nanotechnology Excellence (CCNEs):
The primary goal
of the CCNEs is to integrate nanotechnology development
into basic and
applied cancer research. Each center will be affiliated
with a NCI
Comprehensive Cancer Center, university, or research
center of
engineering and physical science. By leveraging existing
NCI resources,
these centers will bridge gaps in the development
pipeline from
materials discovery to preclinical testing.
* Multidisciplinary research
teams: Given the multidisciplinary nature
of nanotechnology research, investigators with basic
science and
clinical backgrounds will require training to optimize
the development
and translation of nanotechnologies toward clinical
oncology
applications. The NCI will initially use existing
career development
mechanisms to direct talent to this area, create incentives
for cross-
disciplinary research, and foster collaboration through
training.
* Nanotechnology platforms
for cancer research: Over the next five
years, investigator-initiated and directed project
research will be
supported in six key programmatic areas: molecular
imaging and early
detection, in vivo imaging, reporters of efficacy
(e.g., real-time
assessment of treatment), multifunctional therapeutics,
prevention and
control, and research enablers (opening new pathways
for research).
* Nanotechnology Characterization
Laboratory (NCL): The NCL will perform
and standardize the pre-clinical characterization
of nanomaterials
developed by researchers from academia, government,
and industry. The
NCL will serve as a national resource and knowledge
base for cancer
researchers, and facilitate the accelerated regulatory
review and
translation of nanomaterials and devices into the
clinical realm.
The
NCI recently signed a memorandum of understanding
and an interagency agreement with the National Institute
of Standards and Technology to partner with the NCI
in this characterization and standardization effort.
The NCI will also be working to expand collaborations
with the U.S. Food and Drug Administration (FDA) to
help define the critical pathway for nanotechnologies
to reach the clinic.
Among the key components of the Cancer Nanotechnology
Plan are milestones to measure success over two time
periods. Within the first three years, the plan calls
for acceleration of projects that hold promise for
near-term clinical application. After three years,
the Alliance will focus on developing solutions to
address more difficult technological and biological
problems that have the potential to impact detection
and treatment.
"We are already seeing how nanotechnology is
transforming our ability to translate research advances
into clinical advances," said Samuel Wickline,
M.D., Professor of Medicine, Physics and Biomedical
Engineering at Washington University, St. Louis, Mo.,
and NCI grantee for nanotechnology research. "The
possibilities are enormous for finding very small
cancers far earlier than ever before and treating
them with powerful drugs at the tumor site alone,
while at the same time reducing any harmful side effects.
This initiative will allow us to explore using this
technology to its full potential."
Recent advances in cancer treatment involving
nanotechnology include:
* Liposomes, the "first
generation" of nanoscale drug delivery devices,
were developed to deliver anticancer therapeutics
directly at tumors.
Specifically, liposomal doxorubicin is being used
to treat certain
forms of cancer, while liposomal amphotericin B treats
fungal
infections often associated with aggressive anticancer
treatments.
* Recently, a nanoparticulate
formulation of the well-known anticancer
compound taxol was submitted to the FDA as a new treatment
for
advanced-stage breast cancer.
Other clinical applications
of nanotechnology have focused on identifying cancer
in its earliest stages, visualizing development of
the disease, delivering improved therapy to increase
the effectiveness and reduce side effects of drugs,
and capturing early signals of drug efficacy.
