SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a document entitled 
``Interpreting Sameness of Gene Therapy Products Under the Orphan Drug 
Regulations.'' The guidance provides FDA's current thinking on certain 
criteria that help determine sameness of human gene therapy products 
for the purpose of orphan-drug designation and orphan-drug exclusivity. 
The guidance is intended to assist stakeholders, including industry and 
academic sponsors who seek orphan-drug designation and orphan-drug 
exclusivity, in the development of gene therapies for rare diseases. 
The guidance focuses specifically on factors FDA intends to consider 
when determining sameness for gene therapy products and does not 
address sameness determinations for other types of products.
    In the Federal Register of January 30, 2020 (85 FR 5445), FDA 
announced the availability of the draft guidance of the

[[Page 54207]]

same title dated January 2020. Additionally, in the Federal Register of 
April 23, 2020 (85 FR 22740), FDA announced that it is extending the 
comment period on the notice published January 30, 2020. FDA received 
several comments on the draft guidance; the comments generally 
supported the approach described in the guidance and requested 
additional clarification. Those comments were considered as the 
guidance was finalized, and changes to the guidance include adding 
clarification and examples, as feasible. In addition, editorial changes 
were made to improve clarity. The guidance announced in this notice 
finalizes the draft guidance dated January 2020.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
current thinking of FDA on ``Interpreting Sameness of Gene Therapy 
Products Under the Orphan Drug Regulations.'' 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.

II. Paperwork Reduction Act of 1995

    While this guidance contains no collection of information, it does 
refer to previously approved FDA collections of information. Therefore, 
clearance by the Office of Management and Budget (OMB) under the 
Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not 
required for this guidance. The previously approved collections of 
information are subject to review by OMB under the PRA. The collections 
of information in 21 CFR part 316 have been approved under OMB control 
number 0910-0167 and the collections of information in 21 CFR part 312 
have been approved under OMB control number 0910-0014.
