FDA Adopts ICH Guidance On Assessing Nonclinical Biodistribution Of Gene Therapy Viral Vectors5/23/2023
An important step in the gene therapy development process is assembling biodistribution data in suitable animals in relation to the intended clinical population. Developing an accurate biodistribution profile is influenced by factors such as the route of administration, dose level(s), dosing regimen, and the animal immune response to the gene therapy product. The FDA adopted this ICH guidance in May 2023, and the EMA plans to adopt it in September 2023.
