[Docket No. FDA-2018-D-2258]


Human Gene Therapy for Rare Diseases; 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 final guidance entitled ``Human Gene Therapy for 
Rare Diseases; Guidance for Industry.'' The final guidance document 
provides recommendations to stakeholders developing a human gene 
therapy (GT) product intended to treat a rare disease in adult and/or 
pediatric patients regarding the manufacturing, preclinical, and 
clinical trial design issues for all phases of the clinical development 
program. Such information is intended to assist sponsors in designing 
clinical development programs for such products, where there may be 
limited study population size and potential feasibility and safety 
issues as well as issues relating to the interpretability of 
bioactivity/efficacy outcomes that may be unique to rare diseases or to 
the nature of the GT product itself. The guidance announced in this 
notice finalizes the draft guidance of the same title dated July 2018.

DATES: The announcement of the guidance is published in the Federal 
Register on January 30, 2020.

Agency guidances at any time as follows:

SUPPLEMENTARY INFORMATION: 

I. Background

    The Orphan Drug Act of 1983 (Pub. L. 97-414) defines a rare disease 
as a disease or condition that affects fewer than 200,000 persons in 
the United States. Since most rare diseases have no approved therapies, 
there is a significant unmet need for effective treatments. However, 
developing safe and effective products to treat rare diseases can be 
challenging. For example, it may be more difficult to find and recruit 
such patients into clinical trials, and many rare diseases exhibit a 
number of variations or subtypes. Consequently, patients may have 
highly diverse clinical manifestations and rates of disease progression 
with unpredictable clinical courses. Despite these challenges, GT-
related research and development continue to grow at a rapid rate, with 
several products advancing in clinical development.
    FDA is announcing the availability of a document entitled ``Human 
Gene Therapy for Rare Diseases; Guidance for Industry.'' This guidance 
provides recommendations to stakeholders developing human GT product 
intended to treat a rare disease in adult and/or pediatric patients 
regarding the manufacturing, preclinical, and clinical trial design 
issues for all phases of the clinical development program. Such 
information is intended to assist sponsors in designing clinical 
development programs for such products, where there may be limited 
study population size and potential feasibility and safety issues as 
well as issues relating to the interpretability of bioactivity/efficacy 
outcomes that may be unique to rare diseases or to the nature of the GT 
product itself.
    In the Federal Register of July 12, 2018 (83 FR 32303), FDA 
announced the availability of the draft guidance of the same title. FDA 
received several comments on the draft guidance and those comments were 
considered as the guidance was finalized. The guidance announced in 
this notice finalizes the draft guidance dated July 2018.
    Elsewhere in this issue of the Federal Register, FDA is announcing 
the availability of two other human gene therapy guidance documents 
entitled ``Human Gene Therapy for Hemophilia; Guidance for Industry'' 
and ``Human Gene Therapy for Retinal Disorders; Guidance for 
Industry.''
    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 recommendations for stakeholders developing 
human GT products for retinal disorders affecting adult and pediatric 
patients. 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

    This guidance refers to previously approved collections of 
information subject to review by the Office of Management and Budget 
(OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3521). 
The collections of information in 21 CFR part 50 have been approved 
under OMB control number 0910-0755; the collections of information in 
21 CFR part 58 have been approved under OMB control number 0910-0119; 
the collections of information in 21 CFR part 312 have been approved 
under OMB control number 0910-0014; the collections of information in 
21 CFR part 601 have been approved under OMB control number 0910-0338; 
the collections of information in the guidance entitled ``Expedited 
Programs for Serious Conditions--Drugs and Biologics'' have been 
approved under OMB control number 0910-0765; and the collections of 
information in the guidance entitled ``Formal Meetings Between the FDA 
and Sponsors or Applicants'' have been approved under OMB control 
number 0910-0429.
