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 Start Printed Page 5445therapies 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In the Federal Register of July 12, 2018 (83 FR 32306), FDA announced the availability of the draft guidance of the same title. FDA received several comments on the draft guidance, and those comments were considered as the guidance was finalized. The guidance announced in this notice finalizes the draft guidance dated July 2018.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.
