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 The draft guidance also 
includes recommendations regarding preclinical considerations to 
support development of GT products for the treatment of hemophilia.

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft document entitled 
``Human Gene Therapy for Hemophilia; Draft Guidance for Industry.'' The 
draft guidance document provides recommendations to stakeholders 
developing GT products for the treatment of hemophilia. The draft 
guidance provides recommendations on the clinical trial design and 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 The draft guidance also 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 hemophilia are being 
developed as single-dose treatments that may provide long-term 
expression of the missing or abnormal coagulation factor in the patient 
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the availability of two other human gene therapy draft guidance 
documents entitled ``Human Gene Therapy for Retinal Disorders; Draft 
Guidance for Industry'' and ``Human Gene Therapy for Rare Diseases; 
Draft Guidance for Industry.''
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 ``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. This guidance is not subject to Executive 
Order 12866.

II. Paperwork Reduction Act of 1995

    This draft guidance refers to previously approved collections of 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. 3501-3520). 
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 211 have been approved under OMB control number 0910-0139; 
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.
