NGS Methods Recommended for Safety Tests
The draft guidance recommends using next-generation sequencing (NGS) methods and bioinformatics in nonclinical studies to evaluate off-target editing and loss of genome integrity for human genome editing products. These recommendations are intended to guide safety testing for products submitted in support of Investigational New Drug (IND) applications and Biologics License Applications (BLA).
Draft Guidance Released; Comment Deadline
The FDA released a draft guidance called "Safety Assessment of Genome Editing in Human Gene Therapy Products Using Next-Generation Sequencing" for sponsors developing human gene editing products. You can submit comments on the draft through https://www.regulations.gov, and comments must be received by July 14, 2026 so the Agency will consider them before it begins work on the final guidance.
Guidance Is Nonbinding; Alternatives Allowed
The draft guidance represents FDA's current thinking but is not binding and does not establish rights. You may use an alternative approach if it satisfies the requirements of applicable statutes and regulations.
