# SUPPLEMENTARY INFORMATION:

## I. Background

                    FDA is announcing the availability of a guidance entitled “Media Fills for                           ( print page 21784)                        Validation of Aseptic Preparations for Positron Emission Tomography (PET) Drugs.” Most PET drugs are designed for parenteral administration and are produced by aseptic processing. The goal of aseptic processing is to make a product that is free of microorganisms and toxic microbial byproducts, such as bacterial endotoxins. The media fill is the performance of an aseptic manufacturing procedure using a sterile microbiological growth medium in place of the drug solution to test whether the aseptic procedures are adequate to prevent contamination during actual drug production. This guidance takes the form of questions and answers written specifically to help manufacturers comply with the Agency's current good manufacturing practices for PET drugs (21 CFR part 212) regarding media fills.                

                    A draft guidance of the same title was announced in the                     **Federal Register**                     on September 30, 2011 (76 FR 60847), and Docket No. FDA 2011-D-0691 was open for comments until December 29, 2011. We received comments from industry and professional societies. We have carefully considered, and where appropriate, we have made corrections, added information, or clarified the information in this guidance in response to the comments or on our own initiative.                

This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the Agency's current thinking on media fills and process simulations for PET drugs. 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 requirements of the applicable statutes and regulations.

## II. Comments

                    Interested persons may submit to the Division of Dockets Management (see                     **ADDRESSES**                    ) either electronic or written comments regarding this document. It is only necessary to send one set of comments. Identify comments with the docket number found in brackets in 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.                

## III. Paperwork Reduction Act of 1995

This 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 212 have been approved under OMB control number 0910-0667.
