This SBIR Phase I project will develop novel nematicides using proprietary chemical design and screening methods. The project will first design, prioritize, and synthesize a set of entirely novel molecules. The project will then evaluate compounds for activity in multiple biological assays with parasitic nematodes and plants. Promising scaffolds will be prioritized for further development in Phase II including assessment of toxicity, manufacturing cost, and additional synthetic opportunities. The broader/commercial impact of the project will be to protect crops against nematodes which result in significant benefit to growers and the environment. The potential value to Divergence is very large, with the current nematicide market of $1 billion under representing the actual value that could be generated. REsulting effective nematicides with superior safety to current prodicts will be of immediate benefit to growers, consumers, and the environment.

DESCRIPTION (provided by applicant): The goal of this project is to develop a rapid and accurate immunodiagnostic test for detection of soil- transmitted helminths (STHs) that can be used without laboratory infrastructure. Human STH infections from whipworm (Trichuris), roundworm (Ascaris), and hookworms (Necator and Ancylostoma) create a substantial burden to worldwide public health. Current infection rates are staggering, with well over one billion people estimated to be harboring at least one of these nematode parasites, causing substantial morbidity. The current global strategy to control STH infections involves mass drug administration (MDA) of anthelmintic medicines without prior diagnosis. However, cure is often not complete and the limited number of available drugs has fueled concerns of parasite resistance. To support this drug administration strategy, clinical research activities have concurrently intensified. These include monitoring for the emergence of drug resistance and the effects of worm infection on childhood growth and development. Despite these needs, no commercial product to detect these parasites is available. All current diagnostic methods require the use of laboratory equipment and clinically trained personnel to identify parasitic species. The most widely-used method is the microscopic detection of parasite eggs, a labor-intensive technique with inadequate sensitivity and specificity. Therefore a rapid, sensitive, specific, and inexpensive method to detect parasitic worm infections without laboratory infrastructure or trained personnel would offer enormous advantages over current methods. Building upon extensive proof-of-concept data with closely related parasites, this proposal aims to develop an immunodiagnostic assay for detection of human STHs. The first step toward feasibility will involve cloning, recombinant expression, and generation of antiserum to select helminth targets, followed by ELISA and western analyses with parasite extracts and clinical samples (Phase I). Once targets providing adequate sensitivity and specificity are validated, further assay optimization, expansion of reagents, and evaluation of multiple epidemiologic settings will commence (Phase II). PUBLIC HEALTH RELEVANCE: Soil-transmitted helminths (STHs, roundworms) currently infect over one billion people globally, causing substantial morbidity and economic loss. The current microscopic method for detecting these parasites is time-consuming, requires laboratory infrastructure, and suffers from poor sensitivity. The goal of this project is to develop a rapid and accurate immunodiagnostic test for STH infections in support of patient management, epidemiologic studies, and surveillance of mass drug administration programs.


Patent
Divergence and IDEXX Laboratories | Date: 2013-03-07

Methods, devices, kits and compositions for detecting the presence or absence of one or more helminthic coproantigens in a sample are disclosed herein. The methods, devices, kits and compositions of the present invention may be used to confirm the presence or absence of roundworm, whipworm and/or hookworm in a fecal sample from a mammal and may also be able to distinguish between one or more helminth infections. Confirmation of the presence or absence of roundworm, whipworm and/or hookworm in the mammal may be made, for example, for the purpose of selecting an optimal course of treating the mammal and/or for the purpose of determining whether the mammal has been rid of the infection after treatment has been initiated.
