[Docket No. FDA-2015-D-5073]

Use of Nucleic Acid Tests To Reduce the Risk of Transmission of 
Hepatitis B Virus From Donors of Human Cells, Tissues, and Cellular and 
Tissue-Based Products; Draft Guidance for Industry; Availability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 draft document entitled ``Use of Nucleic Acid 
Tests to Reduce the Risk of Transmission of Hepatitis B Virus from 
Donors of Human Cells, Tissues, and Cellular and Tissue-Based Products; 
Draft Guidance for Industry.'' The draft guidance document provides 
establishments that make donor eligibility determinations for donors of 
human cells, tissues, and tissue-based products (HCT/Ps), with 
recommendations concerning the use of FDA-licensed nucleic acid tests 
(NAT) in donor testing for hepatitis B virus (HBV) deoxyribonucleic 
acid (DNA). The draft guidance, when finalized, is intended to 
supplement previous FDA recommendations to HCT/P establishments 
concerning donor testing for hepatitis B surface antigen (HBsAg) and 
total antibody to hepatitis B core antigen (anti-HBc), in the document 
entitled ``Guidance for Industry: Eligibility Determination for Donors 
of Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/
Ps)'' dated August 2007 (2007 Donor Eligibility Guidance).

10.115(g)(5)), to ensure that the Agency considers your comment on this 
draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by April 7, 2016.

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft document entitled 
``Use of Nucleic Acid Tests to Reduce the Risk of Transmission of 
Hepatitis B Virus from Donors of Human Cells, Tissues, and Cellular and 
Tissue-Based Products; Draft Guidance for Industry.'' The draft 
guidance document provides establishments that make donor eligibility 
determinations for donors of HCT/Ps, with recommendations concerning 
the use of FDA-licensed NAT in donor testing for HBV DNA. FDA considers 
the use of FDA-licensed HBV NAT in testing HCT/Ps donors to be 
necessary to adequately and appropriately reduce the risk of 
transmission of HBV. The FDA-licensed HBV NAT can detect evidence of 
the viral infection at an earlier stage than the HBsAg and total anti-
HBc tests. Therefore, FDA recommends the use of FDA-licensed HBV NAT 
for testing donors of HCT/Ps for evidence of infection with HBV.
    HBV is a major global public health concern and has been 
transmitted by blood transfusions and tissue transplantation. Available 
literature has indicated possible transmissions of HBV by hematopoietic 
stem cells and blood with HBV NAT positive/hepatitis B surface antigen 
(anti-HBs) positive/HBsAg negative blood, irrespective of anti-HBc test 
results. In blood donors, adding the HBV NAT testing for HBV reduces 
the residual risk of transmission of HBV infection beyond that which 
can be achieved by screening donors using only HBsAg and total anti-HBc 
tests. In addition, it can detect breakthrough infections in previously 
vaccinated individuals who are exposed to the virus, and HBV mutants 
appear to be more likely detected by HBV NAT than by HBsAg assays.
    In the United States, there are currently FDA-licensed HBV NAT 
assays with an indication for screening donor blood samples for Whole 
Blood and Blood components, other living donors (individual organ 
donors when specimens are obtained while the donor's heart is still 
beating), and blood specimens from cadaveric (non-heart-beating) 
donors. Some of these are multiplex assays that can simultaneously 
detect HIV, HCV, and HBV in a single blood specimen, thus improving the 
feasibility of routine NAT testing for HBV. By analogy to the 
experience in the blood donor setting, it is reasonable to expect that 
the residual risk of transmission of HBV infection would be reduced by 
adding HBV NAT to the testing strategy for HCT/P donors. HBV NAT's 
potential utility in further reducing risk of HBV transmission by 
transplantation is mainly restricted to the early HBsAg-negative phase 
of infection. In summary, the available scientific data and the 
availability of FDA-licensed assays support a recommendation that all 
HCT/Ps donors should be tested using an FDA-licensed HBV NAT. The draft 
guidance, when finalized, is intended to supplement previous FDA 
recommendations to HCT/P establishments concerning donor testing for 
HBsAg and total anti-HBc, in the 2007 Donor Eligibility Guidance.
    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 the ``Use of 
Nucleic Acid Tests to Reduce the Risk of Transmission of Hepatitis B 
Virus from Donors of Human Cells, Tissues, and Cellular and Tissue-
Based Products.'' 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.
