Chembio Diagnostic Systems Inc and the Infectious Disease Research Institute (IDRI) today announced they have entered into a milestone-based agreement pursuant to which Chembio will use its patented dual path platform technology (DPP®) and other Chembio capabilities to design, develop and manufacture a low-cost device for the diagnosis of visceral leishmaniasis.
This step is critical to IDRI’s program funded under a grant from the Bill & Melinda Gates Foundation for the development of accurate, rapid and affordable methods of diagnosis for patients suffering from visceral leishmaniasis in Africa. This announcement was made at the 96th Annual Meeting of the American Association of Immunologists (Immunology 2009) held May 8 to 12 in Seattle.
Most visceral leishmaniasis cases occur in poor populations living in remote areas far from healthcare centers. In these settings, the disease often co-exists with malaria and other debilitating parasitic infections that exhibit similar symptoms, making diagnosis difficult. In these challenging conditions, the traditional labor-intensive and complex diagnostic procedures—invasive removal of bone marrow, spleen and lymph node tissues for microscopic examination and isolation of the parasite by culture—are neither feasible nor field-friendly.
"We are actively working to develop a rapid and simple test that could be used in the field in Africa to diagnose visceral leishmaniasis by using no more than a drop of blood," said Dr. Steven Reed, Founder and Head of IDRI’s Research and Development Program. "This would dramatically improve early detection of visceral leishmaniasis, making current treatments more effective and decreasing transmission rates."
Rapid diagnostic tests are made of two major components: the reagents which are selected to react with specific immunologic components present in the blood of infected patients, and the device which acts as a physical support for the reagents. Diagnostic devices can be as simple as strips of paper or plastic cassettes. These simple tests do not require highly skilled laboratory staff and can be done in the field with results usually available within the next ten to fifteen minutes.
Curt Malloy, SVP Operations and General Counsel of IDRI, said, "Chembio has significant experience in the development, manufacturing and distribution of diagnostic tests, particularly in the developing world. IDRI will provide the reagents for the test and, with our financial support, Chembio will develop a reliable diagnostic device that can be manufactured at low-cost. This will be paramount to ensure affordability of the test when ready for implementation."
"We are thrilled to be able to collaborate with IDRI on the complex yet urgent task of controlling visceral leishmaniasis in developing countries," commented Larry Siebert, Chairman and President of Chembio. "Working alongside IDRI, we will apply our DPP® and other technologies to create a low-cost diagnostic device to help fight this disease that has been ignored for too many years," commented Javan Esfandiari, Senior Vice President of R&D for Chembio.
About Visceral leishmaniasis
Visceral leishmaniasis (VL) is a serious, potentially lethal, systemic parasitic illness that has caused epidemics in India, Southeast Asia, Africa and Latin America. Leishmania parasites are transmitted to humans through the bite of infected sand flies. Patients with VL develop infections of their liver, spleen, and bone marrow and may die if the infection goes untreated. About 500,000 new cases of visceral leishmaniasis occur each year, and 10% of these patients—mostly children—die because their disease cannot be accurately diagnosed in a timely fashion.
