Hapten Sciences and Particle Sciences are working together to move Hapten’s poison ivy, oak, and sumac therapy into clinical trials. According to Memphis-based Hapten, its injectable small-molecule therapy acts like a vaccine to lessen or eliminate contact dermatitis caused by exposure to urushiol oil in the plants. Particle Sciences will manufacture the therapy, which contains urushiol derivatives, for Phase I/II clinical studies scheduled for this year.
