availability of a draft document entitled ``Guidance for Industry: 
Design and Analysis of Shedding Studies for Virus or Bacteria-Based 
Gene Therapy and Oncolytic Products'' dated July 2014. The draft 
guidance document provides sponsors of virus or bacteria-based gene 
therapy products (VBGT products) and oncolytic viruses or bacteria 
(oncolytic products) with recommendations on how to conduct shedding 
studies during preclinical and clinical development.

DATES: Although you can comment on any guidance at any time (see 21 CFR 
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draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by November 19, 2014.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft document entitled 
``Guidance for Industry: Design and Analysis of Shedding Studies for 
Virus or Bacteria-Based Gene Therapy and Oncolytic Products'' dated 
July 2014. The draft guidance document provides sponsors of oncolytic 
and VBGT products with recommendations on how to conduct shedding 
studies during preclinical and clinical development. Oncolytic and VBGT 
products are derived from infectious viruses or bacteria. In general, 
these product-based viruses and bacteria are not as infectious or as 
virulent as the parent strain of virus or bacterium. Nonetheless, FDA 
is issuing this guidance because the possibility that infectious 
product-based viruses and bacteria may be shed by a patient raises 
safety concerns related to the risk of transmission to untreated 
individuals. To understand the risk associated with product shedding, 
sponsors should collect data in the target patient population in 
clinical trials before licensure.
    The draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 this topic. It does 
not create or confer any rights for or on any person and does not 
operate to bind FDA or the public. An alternative approach may be used 
if such approach satisfies the requirement of the applicable statutes 
and regulations.

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    The draft guidance refers to previously approved collections of 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; the collections of information in 21 CFR 
part 600 have been approved under OMB control number 0910-0308; the 
collections of information in 21 CFR part 601 have been approved under 
OMB control number 0910-0338; and the collections of information in 21 
CFR part 50 have been approved under OMB control number 0910-0755.

III. Comments

    The draft guidance is being distributed for comment purposes only 
and is not intended for implementation at this time. Interested persons 
may submit either electronic comments regarding this document to http://www.regulations.gov or written comments to the Division of Dockets 
Management (see ADDRESSES). It is only necessary to send one set of

the heading of this document. Received comments may be seen in the 
Division of Dockets Management between 9 a.m. and 4 p.m., Monday 
through Friday, and will be posted to the docket at http://www.regulations.gov.

IV. Electronic Access
