SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a final guidance entitled ``Human Gene Therapy for 
Hemophilia; Guidance for Industry.'' The guidance document provides 
recommendations to stakeholders developing human gene therapy (GT) 
products for the treatment of hemophilia. The guidance provides 
recommendations on the clinical trial design and related development of 
coagulation factor VIII (hemophilia A) and IX (hemophilia B) activity 
assays, including how to address discrepancies in factor VIII and 
factor IX activity assays. The guidance also includes recommendations 
regarding preclinical considerations to support development of GT 
products for the treatment of hemophilia. 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this notice finalizes the draft guidance of the same title dated July 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.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a document entitled ``Human 
Gene Therapy for Hemophilia; Guidance for Industry.'' The guidance 
document provides recommendations to stakeholders developing GT 
products for the treatment of hemophilia. The guidance provides 
recommendations on the clinical trial design and related development of 
coagulation factor VIII (hemophilia A) and IX (hemophilia B) activity 
assays, including how to address discrepancies in factor VIII and 
factor IX activity assays. The guidance also includes recommendations 
regarding preclinical considerations to support development of GT 
products for the treatment of hemophilia.
    Hemophilia therapy in the United States has progressed from 
replacement

therapies for on-demand treatment of bleeding to prophylaxis to reduce 
the frequency of bleeding. GT products for the treatment of hemophilia 
are being developed as single-dose treatments that may provide long-
term expression of the deficient coagulation factor at steady levels to 
reduce or eliminate the need for exogenous factor replacement.
    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 Retinal Disorders; Guidance for 
Industry'' and ``Human Gene Therapy for Rare Diseases; Guidance for 
Industry.''
    In the Federal Register of July 12, 2018 (83 FR 32306), 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announced the availability of the draft guidance of the same title.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.
    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 ``Human Gene Therapy for Hemophilia.'' 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.

OMB control number 0910-0119; the collections of information in 21 CFR 
part 211 have been approved under OMB control number 0910-0139; the
