St. Louis (September 24, 2007) - Divergence, Inc. announced that it has been awarded
a Phase II Small Business Innovation Research ("SBIR") grant from the National Institutes of Health -
National Institute for Allergy and Infectious Diseases ("NIH-NIAID") in the amount of $734,000. The
grant, entitled "Functional Genomic Approach to Macrofilaricide Discovery," is focused on the discovery
of drugs for preventing and curing infections by filarial parasites, long thread-like worms. The principal
investigator for this grant is James P. McCarter, M.D., Ph.D., Divergence's President and Chief Scientific
Officer. Divergence also announced the publication in the journal Science of the genome of the filarial
parasite Brugia malayi, an analysis by an international team of scientists that included four Divergence
co-authors.
Lymphatic filariasis and onchocerciasis, both caused by filarial parasites, are among the most important
tropical diseases. Lymphatic filariasis, or elephantiasis, causes massive swelling of limbs and, with 140
million cases, is the second leading cause of long-term disability worldwide. Onchocerciasis, also called
river blindness, results in painful itching and damage to the cornea and retina. It is a major cause of
infectious blindness. Coordinated global efforts are underway to control both diseases, but current drugs
are incapable of eliminating the adult worms that can survive for upwards of a decade, thus making the
cure for such infections difficult. Drug resistance has also been detected in the worms causing river
blindness.
"Filarial infections cause substantial human morbidity, especially in Africa and Southeast Asia," said
McCarter. "A drug that is active against all stages of these parasites could provide dramatic improvement
in the quality of life and productivity of millions of people. Additionally, molecules resulting from the
project could be active as veterinary anthelmintics and plant nematicides."
The generation of the draft sequence of Brugia malayi, published in the September 21, 2007 issue of Science,
is the first available genome for any parasitic nematode. The project, which involved laboratories worldwide
including Divergence, was initiated by the Institute for Genomic Research and funded by NIH-NIAID. The
identification of over 12,000 Brugia genes provides new avenues for the discovery and development of
antiparasitic drugs. "At this pivotal time, the SBIR support which Divergence has received from NIH-NIAID
will enable us to move rapidly toward the identification of candidate molecules for the control of filarial
diseases," said McCarter.
Grants remain an important source of funding for Divergence. Divergence has been awarded funding totaling
nearly $6 million from the NIH, National Science Foundation, United States Department of Agriculture,
Environmental Protection Agency, World Health Organization, and National Corn Growers Association.
Divergence is a research and development company dedicated to the discovery of effective and ecologically
sound strategies for the control of parasites and other pests. The company's initial focus is on parasitic
nematodes, one of the world's major pest groups. Nematodes are roundworms that cause billions of dollars in
damage annually to numerous crops, including soybeans, corn, cotton, strawberries, and bananas. Major
nematode-induced human diseases, besides lymphatic filariasis and onchocerciasis, include hookworm,
roundworm, and whipworm. Nematodes also cause widespread disease in animals, including intestinal worms
in livestock and pets. Filarial parasites of animals include canine and feline heartworm.
