Scientific Advisors

ODG’s development efforts benefit from collaboration with dedicated Scientific Advisors having expertise in various aspects of drug development. Serving generously on a pro bono basis, these advisors recommend approaches to scientific work, outlining studies that answer questions in an efficient manner, thus making the most cost-effective use of donor funds. Further, their advice shortens the time needed to develop oxfendazole for patients who are in need of its antiparasitic effects.
