Single Ascending Dose Safety Study of Oxfendazole

This research is being done to learn about the safety in humans of a medicine that is already used in cows and pigs to treat worms. The medicine may be useful for people who have these or other worms. The medicine will be studied first in healthy people, who will be given a very small amount of the medicine once. If the smallest amount of medicine is found to be safe, a slightly higher amount will be given to a new group of volunteers. The highest amount that will be tested is similar to the amount given to animals. If the medicine can be given safely to healthy people in the planned amounts, a later study will be done in people who have worms to see if the medicine kills the worms.
