MIV Therapeutics' Newest Technology Breakthrough Expands Family of Proprietary ``Smart'' Drug Delivery Systems Friday September 2, 4:01 pm ET
Advanced Coating Composite for Enhanced Medical Devices Complements Company's Proprietary HAp Technologies
VANCOUVER, British Columbia--(BUSINESS WIRE)--Sept. 2, 2005--MIV
Therapeutics, Inc. (OTCBB:MIVT - News), a developer of next-generation
biocompatible stent coatings and drug delivery technologies for the
treatment of cardiovascular disease and therapeutic applications on
implantable medical devices, announced today a milestone scientific
achievement related to the development of a new drug delivery system
with "smart" drug-eluting coating technologies.

This is the newest member of a family of "smart" and highly
innovative proprietary coating technologies developed by MIVT, which
could have important, innumerable therapeutic benefits for patients
who require the controlled, gradual release of drugs from implanted
medical devices.
The "smart" drug eluting system is designed to improve the overall
biocompatibility of polymer composites and to increase the control of
drug delivery characteristics. Engineering specifications used in this
novel system provide considerably improved drug release flexibility,
including the option of releasing a wide variety of drugs to address
the various needs of a patient's particular pathological condition
over extended periods of time.
MIVT's latest "smart" coating technology carries with it the
promise of providing unprecedented, highly personalized and optimal
therapeutic benefits to patients who require implantable medical
devices.
"This unique structural configuration allows unprecedented,
complex new therapeutic possibilities, such as the delivery of 'drug
cocktails' when medically necessary," said Alan Lindsay, CEO of MIVT.
"As a proud new member of the family of MIVT's advanced drug delivery
systems, this latest smart coating technology provides a unique new
methodology of controlled drug delivery in a manner responsive to a
patient's real-life clinical needs."
MIVT's innovative technology of separating the drug molecules from
the polymeric coating molecules in this coating is intended to
eliminate the risk of undesired interactions between the two molecule
types.
In addition, this advanced technology is capable of controlling
both the pace and amount of drugs delivered, further enhancing the
device's potential therapeutic benefits and its potential for
"multi-platform" applications.
Dr. Dean-Mo Liu, Chief Scientist of Drug Delivery Technologies at
MIVT, noted, "This coating's unique physical characteristics give our
proprietary drug-release technology exceptional flexibility for
potential application on a wide range of medical devices, including
vascular stents and an exceptionally wide range of other implantable
medical devices."
Among the coating technology's most novel characteristics is its
well-organized configuration of encapsulated nano-chambers that can
provide more effective and gradual drug release. These chambers, each
of which measures between a few nanometers and several micrometers in
diameter, are contained in a multi-layered configuration in which the
respective size and structure of the cells can be controlled to suit
specific drug release requirements.
This latest "smart" coating technology was developed entirely at
MIVT's research and development facility in Vancouver, Canada, by a
team of researchers under the stewardship of Dr. Liu, and including
MIVT's Maurice Lien and Doug Smith. The technology is 100%-owned by
MIVT.
Stents are expandable medical devices that doctors may place
inside clogged or otherwise narrowed arteries of patients with
vascular disease, in order to maintain healthy blood flow.
Drug-eluting stents deliver medicines at the point of implantation to
reduce unwanted side effects.
MIVT's proprietary coating technologies are increasingly being
recognized for providing an exceptional degree of biocompatibility
compared to traditional bare metal stents and less advanced coating
technologies on the market.
"This latest coating invention adds new elements of flexibility
and efficacy to our impressive platform of drug-eluting coating
technology options, which can be applied in innumerable ways," said
Dr. Liu. "Moreover, its unique composite properties can also
complement the exceptional biocompatibility of MIVT's own
Hydroxyapatite (HAp) coatings -- reinforcing the potential medical
benefits to the patient."
MIVT is committed to contributing needed technology innovations in
the fast-growing multi-billion-dollar global marketplace for
implantable, drug-eluting stents and other cardiovascular disease
solutions. The Company recently announced that it has received a $4.14
million equity financing to accelerate these and other R&D efforts.
In addition, in collaboration with the University of British
Columbia, MIVT focuses on the development of its HAp-based coating
formulations to protect surrounding tissue from chemical interaction
with bare-metal stents, an interaction which typically causes an
aggressive immune response, resulting in restenosis, or re-narrowing
of arteries, and risks of thrombus in the stented artery.
Hydroxyapatite is a naturally occurring material, a component of hard
tissue found in human teeth and bone that enables the surface of
metallic stents to virtually mimic the natural state of
structurally-sound 100% biocompatible and bio-active tissue.
The Company believes its arsenal of novel coating technologies
also has the potential for medical applications including dental, hip
and bone repair implants.
About MIV Therapeutics, Inc.
MIV Therapeutics, Inc. is developing a next-generation line of
advanced biocompatible coatings for passive and drug-eluting
application on cardiovascular stents and for application on other
implantable medical devices. The Company's ultra-thin coating
formulation is designed primarily to protect surrounding tissue from
the chemical interaction with metal stents. The Company's unique
ultra-thin coating has been derived from a biocompatible material
called hydroxyapatite (HAp) that during in-vivo animal trials
demonstrated excellent safety and superior healing properties pursued
by the science in the field of advanced implantable drug delivery
systems. Hydroxyapatite is a bioactive porous material that makes up
the bone mineral and matrix of teeth. It is widely used as a bone
substitute material and for coating implantable fixation devices in
orthopedic, dental and other applications. The Company's novel drug
eluting technologies based on Hydroxyapatite provide attractive
alternative solution to polymer-based drug eluting coatings currently
in the stent market. The Company's drug eluting coating is designed to
suit a broad range of implantable medical devices which may benefit
from a highly customizable drug release profile. MIVT reached a
Collaborative Research Agreement (CRA) with the University of British
Columbia and supported a research and development grant from the
Natural Sciences and Engineering Research Council of Canada (NSERC) in
2002 for the development of Hydroxyapatite as a drug-eluting coating.
In December 2004 MIVT received a Government grant for the research
program titled "Development of Novel Drug Eluting Composite Coatings
for Cardiovascular Stents" under the National Research Council --
Industrial Research Assistance Program (NRC-IRAP). Under this
sponsorship the Company will progress to the development stage, which
is expected to finalize the drug-eluting research and development
Program. For more information, please visit:
