Our work to advance oxfendazole’s development for human use is the beneficiary of major clinical support through the U.S. National Institutes of Health (via internal work agreements and external grants), charitable grants (ACX, Open Philanthropy) and donations from foundations and individuals (both small and large).

These funders are presently supporting work that includes a clinical (in human) Proof of Concept study in Peru to demonstrate oxfendazole’s efficacy against a presently poorly treated worm (Trichuris trichiura), studies of oxfendazole’s potential to interact with other medications (drug-drug interaction studies), studies to determine the way that oxfendazole is broken down (metabolized) in different animal species, and toxicology studies in rats and a non-rodent species.

Some of these studies must be conducted before we can advance to Phase III development, the step following the one in which we are presently engaged, Phase II. The cost of the first study listed above is in the range of tens of thousands of dollars, whereas the cost of studies 2 through 4 are in the range of $200-400K each.

Please consider supporting our work to advance a better medicine for the treatment of several Neglected Tropical Diseases.
