Testing of Retroviral Vector-Based Human Gene Therapy Products 
for Replication Competent Retrovirus During Product Manufacture and 
Patient Follow-up; Draft Guidance for Industry; Availability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 ``Testing of Retroviral 
Vector-Based Human Gene Therapy Products for Replication Competent 
Retrovirus During Product Manufacture and Patient Follow-up; Draft 
Guidance for Industry.'' The draft guidance document provides sponsors 
of retroviral vector-based human gene therapy products recommendations 
regarding the testing for replication competent retrovirus (RCR) during 
the manufacture of retroviral vector-based products, and during follow-
up monitoring of patients who have received retroviral vector-based 
products. Recommendations include the identification and amount of 
material to be tested, and general testing methods. In addition, 
recommendations are provided on monitoring patients for evidence of 
retroviral infection after administration of retroviral vector-based 
gene therapy products. The draft guidance, when finalized, is intended 
to supersede the document entitled ``Guidance for Industry: 
Supplemental Guidance on Testing for Replication Competent Retrovirus 
in Retroviral Vector Based Gene Therapy Products and During Follow-up 
of Patients in Clinical Trials Using Retroviral Vectors,'' dated 
November 2006. The draft guidance, when finalized, is also intended to 
supplement the documents entitled ``Long Term Follow-Up After 
Administration of Human Gene Therapy Products; Draft Guidance for 
Industry'' and ``Chemistry, Manufacturing, and Control Information for 
Human Gene Therapy Investigational New Drug Applications; Draft 
Guidance for Industry,'' when these draft guidance documents are 
finalized.

DATES: Submit either electronic or written comments on the draft 
guidance by October 10, 2018 to ensure that the Agency considers your 
comment on this draft guidance before it begins work on the final 
version of the guidance.

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft document entitled 
``Testing of Retroviral Vector-Based Human Gene Therapy Products for 
Replication Competent Retrovirus During Product Manufacture and Patient 
Follow-up; Draft Guidance for Industry.'' The draft guidance document 
provides sponsors of retroviral vector-based human gene therapy 
products recommendations regarding the testing for RCR during the 
manufacture of retroviral vector-based products, and during follow-up 
monitoring of patients who have received retroviral vector-based 
products. Recommendations are also provided for RCR testing during 
manufacture, including identification and amount of material to be 
tested, and general testing methods. In addition, recommendations are 
provided on monitoring patients for evidence of retroviral infection 
after administration of retroviral vector-based gene therapy products. 
The draft guidance, when finalized, is intended to supersede the 
document entitled ``Guidance for Industry: Supplemental Guidance on 
Testing for Replication Competent Retrovirus in Retroviral Vector Based 
Gene Therapy Products and During Follow-up of Patients in Clinical 
Trials Using Retroviral Vectors,'' dated November 2006. The draft 
guidance, when finalized, is also intended to supplement the ``Long 
Term Follow-Up After Administration of Human Gene Therapy Products; 
Draft Guidance for Industry'' and ``Chemistry, Manufacturing, and 
Control Information for Human Gene Therapy Investigational New Drug 
Applications; Draft Guidance for Industry,'' when these draft guidance 
documents are finalized. Elsewhere in this issue of the Federal 
Register, FDA is announcing the availability of these other two draft 
guidance documents.
    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 FDA's current thinking on testing of 
retroviral vector-based human gene therapy products for replication 
competent retrovirus during product manufacture and patient follow-up. 
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

    The draft guidance refers to previously approved collections of 
information found in FDA regulations. These collections of information 
are 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 312 have been approved under 
OMB control number 0910-0014; and the collections of information in 21 
CFR part 601 have been approved under OMB control number 0910-0338.

III. Electronic Access

    Persons with access to the internet may obtain the draft guidance 
at either https://www.fda.gov/BiologicsBloodVaccines/GuidanceComplianceRegulatoryInformation/Guidances/default.htm or
