The final guidance provides harmonized recommendations for the conduct and overall design of nonclinical biodistribution (BD) studies for gene therapy (GT) products. The recommendations in the guidance endeavor to facilitate the development of investigational GT products, while avoiding unnecessary use of animals, in accordance with the 3Rs (reduce/refine/replace) principles. The final guidance replaces the draft guidance entitled "S12 Nonclinical Biodistribution Considerations for Gene Therapy Products" issued on September 9, 2021.
