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Human Gene Therapy Products for Replication Competent Retrovirus During Product Manufacture and Patient Follow-up; Draft Guidance for Industry.” The draft guidance document provides sponsors of retroviral vector-based human gene therapy products recommendations regarding the testing for replication competent retrovirus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 The draft guidance, when finalized, is intended to supersede the document entitled “Guidance for Industry: Supplemental Guidance on Testing for Replication Competent Retrovirus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 The draft guidance, when finalized, is also intended to supplement the documents entitled “Long Term Follow-Up After Administration of Human Gene Therapy Products; Draft Guidance for Industry” and “Chemistry, Manufacturing, and Control Information for Human Gene Therapy Investigational New Drug Applications; Draft Guidance for Industry,” when these draft guidance documents are finalized.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Submit either electronic or written comments on the draft guidance by October 10, 2018 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.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Human Gene Therapy Products for Replication Competent Retrovirus During Product Manufacture and Patient Follow-up; Draft Guidance for Industry.” The draft guidance document provides sponsors of retroviral vector-based human gene therapy products recommendations regarding the testing for RCR during the manufacture of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 https://www.regulations.gov.
