Easier global approval for dewormers
If you make or test worm‑killing medicines for animals, FDA released a final guidance (GFI #90/VICH GL7) on June 24, 2026 that gives study design recommendations to help effectiveness data be accepted worldwide (including the European Union, Japan, and the United States). This guidance is meant to make it easier and faster for veterinary drug makers and veterinarians to show products work, which the notice says will save time and money.
No new paperwork under PRA
The guidance states it contains no new collection of information under the Paperwork Reduction Act. It refers to previously approved FDA information collections in 21 CFR part 514 under OMB control number 0910-0032, so affected companies will not face new paperwork from this guidance.
