[Docket No. FDA-2026-D-1255]


Safety Assessment of Genome Editing in Human Gene Therapy 
Products Using Next-Generation Sequencing; Draft Guidance for Industry; 
Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a draft document entitled ``Safety Assessment of 
Genome Editing in Human Gene Therapy Products Using Next-Generation 
Sequencing; Draft Guidance for Industry.'' The draft document provides 
recommendations for next-generation sequencing (NGS)-based methods used 
in nonclinical studies that will likely be needed to support initiation 
of clinical trials of investigational human genome editing (GE) 
products.

DATES: Submit either electronic or written comments on the draft 
guidance by July 14, 2026 to ensure that the Agency considers your 
comment on this draft guidance before it begins work on the final 
version of the guidance.

ADDRESSES: You may submit comments on any guidance at any time as 
follows:

Electronic Submissions

    Submit electronic comments in the following way:
     Federal eRulemaking Portal: https://www.regulations.gov.

does not include any confidential information that you or a third party 
may not wish to be posted, such as medical information, your or anyone 
else's Social Security number, or confidential business information, 
such as a manufacturing process. Please note that if you include your 
name, contact information, or other information that identifies you in 
the body of your comments, that information will be posted on https://www.regulations.gov.

submissions): Dockets Management Staff (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
     For written/paper comments submitted to the Dockets 
Management Staff, FDA will post your comment, as well as any 
attachments, except for information submitted, marked and identified, 
as confidential, if submitted as detailed in ``Instructions.''
    Instructions: All submissions received must include the Docket No. 
FDA-2026-D-1255 for ``Safety Assessment of Genome Editing in Human Gene 
Therapy Products Using Next-Generation Sequencing; Draft Guidance for 
Industry.'' Received comments will be placed in the docket and, except 
for those submitted as ``Confidential Submissions,'' publicly viewable 
at https://www.regulations.gov or at the Dockets Management Staff 
between 9 a.m. and 4 p.m., Monday through Friday, 240-402-7500.
     Confidential Submissions--To submit a comment with 
confidential information that you do not wish to be made publicly 
available, submit your comments only as a written/paper submission. You 
should submit two copies total. One copy will include the information 
you claim to be confidential with a heading or cover note that states 
``THIS DOCUMENT CONTAINS CONFIDENTIAL INFORMATION.'' The Agency will 
review this copy, including the claimed confidential information, in 
its consideration of comments. The second copy, which will have the 
claimed confidential information redacted/blacked out, will be 
available for public viewing and posted on https://www.regulations.gov. 
Submit both copies to the Dockets Management Staff. If you do not wish 
your name and contact information to be made publicly available, you 
can provide this information on the cover sheet and not in the body of 
your comments and you must identify this information as 
``confidential.'' Any information marked as ``confidential'' will not 
be disclosed except in accordance with 21 CFR 10.20 and other 
applicable disclosure law. For more information about FDA's posting of 
comments to public dockets, see 80 FR 56469, September 18, 2015, or

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft document entitled 
``Safety Assessment of Genome Editing in Human Gene Therapy Products 
Using Next-Generation Sequencing; Draft Guidance for Industry.''
    This draft guidance is intended for sponsors developing human gene 
therapy products involving GE technologies. Clinical development 
programs of human GE products should address both the risks associated 
with the gene therapy product itself as well as the additional risks 
associated with GE, including off-target editing and

[[Page 20174]]

unintended consequences. The recommendations in this draft guidance may 
guide stakeholders on designing nonclinical studies that uses NGS 
methods and bioinformatics to evaluate the potential safety risks 
associated with off-target editing and loss of genome integrity in 
human GE products submitted in support of Investigational New Drug 
applications and Biologics License Applications.
    The recommendations provided in this draft guidance are in addition 
to the nonclinical, clinical, and CMC considerations discussed in the 
``Guidance for Industry: Human Gene Therapy Products Incorporating 
Human Gene Editing'' dated January 2024.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the current thinking of FDA on ``Safety 
Assessment of Genome Editing in Human Gene Therapy Products Using Next-
Generation Sequencing.'' It does not establish any rights for any 
person and is not binding on FDA or the public. You can use an 
alternative approach if it satisfies the requirements of the applicable 
statutes and regulations.
    As we develop any final guidance on this topic, FDA will consider 
comments on costs or cost savings the guidance may generate, relevant 
for Executive Order 14192.

II. Paperwork Reduction Act of 1995

    While this guidance contains no collection of information, it does 
refer to previously approved FDA collections of information. The 
previously approved collections of information are subject to review by 
the Office of Management and Budget (OMB) under the Paperwork Reduction 
Act of 1995 (PRA) (44 U.S.C. 3501-3521). The collections of information 
in 21 CFR part 312 relating to the submission of Investigational New 
Drug Applications, including clinical trials, have been approved under 
OMB control number 0910-0014. The collections of information contained 
in 21 CFR part 601 relating to the submission of biologics license 
applications have been approved under OMB control number 0910-0338. The 
collections of information in 21 CFR part 1271 relating to human gene 
therapy products have been approved under OMB control number 0910-0543.

III. Electronic Access
