Harmonized study rules for cat dewormers
FDA issued final Guidance for Industry #113 (VICH GL20) on June 24, 2026 with study design recommendations specific to feline anthelmintics. The guidance is intended to facilitate the universal acceptance of generated effectiveness data so that national and regional regulators can use the same data to meet approval requirements; the guideline was endorsed by regulatory agencies in October 2024.
Guidance is advisory, alternatives allowed
The guidance represents the FDA's current thinking on effectiveness of feline anthelmintics but is not binding. It explicitly states you may use an alternative approach if it satisfies applicable statutes and regulations and was issued consistent with FDA's good guidance practices (21 CFR 10.115).
No new paperwork or data collection
The guidance contains no new collection of information and refers to previously approved collections under 21 CFR part 514 (OMB control number 0910-0032). As stated, the guidance does not create additional Paperwork Reduction Act obligations.
