Chembio Awarded Three Year $3MM NIH SBIR Phase II Grant to Complete DPP® Test for Human Leptospirosis

MEDFORD, N.Y (June 25, 2009) Chembio Diagnostic Systems, Inc. (a wholly-owned subsidiary of Chembio Diagnostics, Inc., OTCBB CEMI) has been awarded a three-year $3 million Small Business Innovative Research (SBIR) Phase II grant from the United States National Institutes of Health (NIH) to fully develop, validate, and commercialize a rapid diagnostic test for leptospirosis for general use worldwide. The test will be developed utilizing Chembio’s patented Dual Path Platform (DPP®) technology together with proprietary reagents developed by Cornell University and the Oswaldo Cruz Foundation at the Brazilian Ministry of Health.

Development of the test will be in collaboration with the Division of Infectious Diseases, Weill Medical College, Cornell University in New York and the Oswaldo Cruz Foundation, the largest biomedical research institution in Latin America.  In the Phase I work completed in 2008, which occurred with this same collaborative group, novel diagnostic targets were identified and evaluated in a prototype test in Chembio’s patented DPP® format. The studies demonstrated that the test prototype had an overall sensitivity of 85% and a specificity of 90% using serum samples of leptospirosis patients from Brazil and Thailand.  Furthermore, the DPP® prototype had a sensitivity of 78% in identifying leptospirosis in the first 7 days of illness, the "window-of-opportunity" during which initiation of antimicrobial therapy provides the greatest benefit.

The lack of an effective diagnostic test has been one of the major barriers to addressing leptospirosis, a life-threatening zoonotic disease, whose global burden is estimated to be as high as 500,000 cases annually. Leptospirosis is an emerging infectious disease problem in industrialized countries such as the US, and is a significant cause of mortality and morbidity among impoverished populations in developing countries. Leptospirosis, especially in the early stage of illness, is often misdiagnosed as dengue, malaria and other causes of acute fever.  The delay in detecting leptospirosis has potentially severe consequences since the disease progresses to cause life-threatening manifestations such as pulmonary hemorrhage syndrome and acute renal failure.

Dr. Albert Ko, Associate Professor of Medicine at Weill Medical College, Cornell University and Visiting Researcher at Oswaldo Cruz Foundation, commented, “The collaboration with Chembio has been successful in applying the selected markers to Chembio’s DPP format. This grant enables us to complete development of the assay and make it available to health professionals and public health authorities as part of an effort in combating this important global infectious disease problem.”

Javan Esfandiari, Senior Vice President of R&D of Chembio, commented, “We are pleased with the recognition that the awarding of this grant by NIH provides Chembio and to our patented DPP® technology. I am most appreciative of the excellent work of Dr Albert Ko from Cornell and Dr. Konstantin Lyashchenko, Chembio’s Senior R&D Director, as well as the rest of Chembio’s R&D team.

About DPP®

The Dual Path Platform immunoassay is a recent innovation in the field of rapid testing for which Chembio received a US patent in 2007. DPP® technology employs two separate and distinct membrane strips, one for the sample migration and one for the test reagents. This unique dual-flow design allows for improved control and management of the sample flow. As a result, the immunological reaction is more efficient than lateral flow tests based upon studies performed by Chembio.

About Weill Cornell Medical College

The Division of Infectious Diseases at Weill Medical College mission encompasses clinical care, research, and education. The Division has 50 full-time and voluntary faculty members and is responsible for the NewYork-Presbyterian Hospital/Weill Cornell Medical Center's Infectious Diseases Clinical Service, the HIV/AIDS Program and the Weill Cornell Travel Medicine Clinic (WCTMC). The Weill Cornell HIV/AIDS Program provides care to ~2,000 HIV-infected persons, in addition to conducting basic and clinical research. The WCTMC is staffed by the faculty and provides travel advice and immunizations for ~3,000 persons annually, in addition to infectious diseases consultations. The Infectious Diseases Fellowship Training Program provides individualized training through faculty guidance, clinical rotations, mentored research, and didactic coursework. The Division has a cadre of internationally recognized physician-scientists who are devoted to basic laboratory and patient-centered research, education and service, both in the United States and abroad (Brazil, Haiti, India, Nigeria, Tanzania, and Tunisia).

EX-99.2

Chembio Presenting DPP® Syphilis at ISSTDR Congress

DPP® HIV, Hepatitis-C & HIV-Hepatitis Combination Oral Fluid Tests in

CDC Study

MEDFORD, N.Y (June 29, 2009).  Chembio Diagnostics, Inc. (OTCBB: CEMI) will present a scientific poster June 30, 2009 describing the performance and other features of its recently completed DPP® Syphilis Screen & Confirm point-of-care test.  The poster will be presented at the 18th International Society for Sexually Transmitted Disease Research (ISSTDR) Congress in London, England by Javan Esfandiari, Chembio’s Senior Vice President of Research & Development.

Chembio has developed the first dual non-treponemal & treponemal POC syphilis test. Utilizing the Company’s patented Dual Path Platform technology, DPP® Syphilis Screen & Confirm permits the simultaneous yet separate detection of both markers at the point-of-care, providing more conclusive evidence, at the point-of-care, of active, untreated disease as compared with current methods, and thereby enabling diagnosis and treatment in a single visit to a clinic. The test therefore represents a considerable advance in diagnosis, as well as in time-to-result and ease of use.

The rate of primary and secondary (P&S) syphilis reported in the United States increased during 2000-2007. In 2007, P&S syphilis cases reported to the United States Centers for Disease Control (CDC) increased 17.5%, and the rate of P&S  syphilis in the United States increased 15.2% in 2007 (3.8 cases per 100,0000), from 2006 (3.3 cases per 100,000). Syphilis remains a significant global public health problem with WHO estimating 12 million new cases of the disease worldwide each year, including 100,000 per year in the United States and 140,000 per year in Western Europe. Standard diagnosis of syphilis in the US employs two separate central laboratory-based non-treponemal screening tests (RPR, VDRL), followed by  a more specific confirmatory treponemal assay.

The test has been developed pursuant to a Cooperative Research & Development Agreement that Chembio entered with the CDC in 2006, as has been previously reported.  Chembio has provided tests for evaluation in an international study being sponsored by the World Health Organization to qualify the product for certain procurement programs, and it is preparing for studies to commercialize this product for commercialization in the United States, Europe and other markets around the world.

ISSTDR was formed in 1977 to strengthen research in sexually transmitted infections. The meetings have been held regularly over the last 30 years, mostly every two years, and have become the most important forum for presentation and discussion of recent findings in this field.  Information concerning the ISSTDR conference can be accessed at  www.isstdrlondon2009.com. Material being presented at the Congress by Chembio will be available soon on Chembio’s web site.

DPP® Tests for HIV and Hepatitis-C in CDC Study

Chembio also announced today that the Centers for Disease Control and Prevention (CDC) in the United States has selected the Company's DPP® HIV, Hepatitis-C (HCV) and its combination HIV/HCV tests to be a part of a program entitled "Opportunity to Collaborate in the Evaluation of Rapid Diagnostic Tests for HIV and HCV".   Each of these products is a qualitative rapid anti-body detection test that can use oral fluid samples or the full matrix of blood samples and all are designed  with Chembio’s patented dual path platform technology.

This program of the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) at the Centers for Disease Control and Prevention (CDC) of the Department of Health and Human Services (DHHS) is arranging for evaluations done in laboratories and in the field to determine the viability of rapid tests for use in screening and/or diagnosis of HIV and HCV in the United States. A number of rapid tests will be evaluated as part of the program, however Chembio’s HIV/HCV will be the only combination test that is designed for point-of-care setting or that can be run on oral fluid or finger stick whole blood samples.  The results of this study will be useful in the Company’s efforts to finalize the design of the HCV products.
