Infectious Disease Research Institute and Chembio to Develop Tests for Leishmaniasis and Leprosy

Joint project will develop accurate, field-friendly, low-cost,
diagnostic tests for two 'neglected diseases' SEATTLE, May 30
/PRNewswire/ -- The Seattle-based Infectious Disease Research
Institute (IDRI) and Chembio Diagnostics, Inc. (OTC:CEMI) (BULLETIN
BOARD: CEMI) have entered into two research and development
agreements for the development of rapid diagnostic tests for
Leishmaniasis and Leprosy, two "neglected diseases" targeted by
IDRI. The tests will be developed by Chembio using Chembio's
patented Dual Path immunoassay test platform (DPP(TM)) and will
incorporate IDRI's proprietary antigens. In preliminary studies
conducted during the first quarter of 2007, Chembio demonstrated
superior analytical sensitivity on certain well-characterized
samples from patients with these diseases. These studies resulted
in the decision by Chembio and IDRI to enter into two Cooperative
Research and Development Agreements to further their joint efforts.
IDRI, which has funding from the National Institutes of Heath and
the Bill and Melinda Gates Foundation for the development of
vaccines and diagnostics for leishmaniasis, and from the American
Leprosy Mission for similar activities in leprosy, actively
partners with industrial organizations to achieve its goals of
developing products to aid in the control of selected diseases.
Following completion of the prototype tests this year, the parties
intend to then seek commitments for procurement of these products
for affected populations globally. The leishmania parasite affects
millions of people worldwide, while leprosy continues to be an
important public health problem, with approximately one million new
cases per year. Access to better diagnostic tools will be essential
for control of theses diseases. ABOUT LEISHMANIASIS Leishmaniasis
is a widespread parasitic disease with frequent epidemics in the
Indian subcontinent, Africa, and Latin America and is a World
Health Organization priority for vaccine development. A complex of
different diseases, Leishmania parasites cause fatal infections of
internal organs, as well as serious skin disease. One of the most
devastating forms of leishmaniasis is a disfiguring infection of
the nose and mouth. The number of cases of leishmaniasis is
increasing, and it is now out of control in many areas.
Leishmaniasis is also on the rise in some developed countries,
specifically southern Europe, as a result of HIV infection.
Available drugs are toxic, expensive, and require long-term daily
injections. Leishmania are protozoan parasites that inhabit
macrophages or the white blood cells of the immune system. The
parasites are transmitted by the bite of small blood sucking
insects (sand flies), which are difficult to control, as they
inhabit vast areas of the planet. It is estimated that about
500,000 new cases of the visceral form (kala-azar or "the killing
disease") occur each year. Most of the deaths occur in children.
Those with the cutaneous forms are often left permanently
disfigured. There are 12 million cases of leishmaniasis worldwide,
two million new cases per year, 500,000 of which are the visceral
form. Leishmaniasis causes hundreds of thousands deaths per year
(70% are children). ABOUT LEPROSY Leprosy, or Hansen's disease, is
a chronic infectious disease caused by the intra-cellular pathogen
Mycobacterium leprae -- a bacterium that is related to the organism
that causes tuberculosis. The bacillus primarily grows within
lesions in the cooler body areas such as the skin, limbs, eyes, and
nasal cavity. The damage of the peripheral nerves leads to muscle
weakness and atrophy, and numbness or loss of sensitivity to touch
and heat in several areas of the skin. Viable leprosy bacilli are
transmitted by droplets from the nose and mouth of infected
persons. The stigma attached to leprosy has often caused those who
contract the disease to be shunned by family, friends, and society.
Approximately 1.6 billion people worldwide are exposed to leprosy,
which is endemic in 24 countries. Approximately 500,000 new cases
are found each year -- over 1,300 cases every day. It is estimated
that four to five million people already suffer from, or have
deformities due to, leprosy. Approximately 20 years ago, it became
possible to treat leprosy. A multidrug therapy (MDT) comprised of
several drugs given orally for a period of six to twenty four or
more months may cure leprosy but can cause severe side effects.
Although combination antibiotic therapy provided during the early
stages of the disease reduces disease progression and spread, poor
diagnostics and lack of access to regular health care mean that
many who develop leprosy are treated only late in the disease,
after disfigurement and transmission to others have already
occurred. ABOUT IDRI The Infectious Disease Research Institute,
Seattle, Washington, is a 501(c)(3) "non-profit biotech" that
develops vaccines, diagnostics, and therapeutics for neglected
diseases, including tuberculosis, leishmaniasis, leprosy, Chagas
disease and others. ABOUT CHEMBIO Chembio Diagnostics, Inc., a
developer and manufacturer of rapid diagnostic tests for infectious
diseases, is on the frontlines of the global battle against the
AIDS pandemic. The Company has received marketing approval from the
FDA for its SURE CHECK(R) HIV 1/2 and HIV 1/2 STAT-PAK(TM) rapid
tests, marketed in the United States by Inverness Medical
Innovations. The Company also manufactures rapid tests for
veterinary Tuberculosis and Chagas disease. In March 2007 Chembio
was issued a United States patent for the Dual Path Platform
(DPP(TM)), a next generation lateral flow platform DPP has
demonstrated significant advantages over currently available
lateral flow methods, including increased sensitivity, sample
flexibility, and multiplexing capabilities. Further information on
