# SUPPLEMENTARY INFORMATION:

## I. Background

FDA is announcing the availability of a final guidance for industry entitled “Interim Policy on Compounding Using Bulk Drug Substances Under Section 503B of the Federal Food, Drug, and Cosmetic Act” (2024 503B Interim Policy Guidance). This guidance finalizes the draft guidance entitled “Interim Policy on Compounding Using Bulk Drug Substances Under Section 503B of the Federal Food, Drug, and Cosmetic Act” issued on December 7, 2023 (88 FR 85293), and replaces the guidance of the same title issued in January 2017 (2017 503B Interim Policy Guidance).

Section 503B of the FD&C Act (21 U.S.C. 353b) sets forth the conditions that must be satisfied for human drug products compounded by an outsourcing facility to be exempt from the following three sections of the FD&C Act: (1) section 505 (21 U.S.C. 355) (concerning the approval of drugs under new drug applications or abbreviated new drug applications); (2) section 502(f)(1) (21 U.S.C. 352(f)(1)) (concerning the labeling of drugs with adequate directions for use); and (3) section 582 (21 U.S.C. 360eee-1) (concerning drug supply chain security requirements). One of the conditions that must be met for a drug product compounded by an outsourcing facility to qualify for these exemptions is that the outsourcing facility does not compound a drug using a bulk drug substance unless: (1) the bulk drug substance appears on a list established by the Secretary of the Department of Health and Human Services identifying bulk drug substances for which there is a clinical need (the 503B bulks list) (see section 503B(a)(2)(A)(i)) or (2) the drug product compounded from such bulk drug substances appears on the drug shortage list in effect under section 506E of the FD&C Act (21 U.S.C. 356e) at the time of compounding, distribution, and dispensing (see section 503B(a)(2)(A)(ii) of the FD&C Act).

FDA is developing the 503B bulks list, and this guidance describes FDA's interim policy regarding outsourcing facilities that compound human drug products using bulk drug substances while the list is being developed. This guidance revises the policy described in FDA's 2017 503B Interim Policy Guidance with respect to categorization of certain substances nominated for inclusion on the 503B bulks list. This guidance ends the categorization of bulk drug substances into Categories 1, 2, or 3 for those bulk drug substances nominated on or after the date of publication of this guidance.

The 2024 503B Interim Policy Guidance describes the conditions under which FDA does not intend to take action against an outsourcing facility for compounding a drug product using certain bulk drug substances that are not eligible for use in compounding under section 503B of the FD&C Act because they do not appear on the 503B bulks list and are not used to compound a drug product that appears on FDA's drug shortage list at the time of compounding, distribution, and dispensing. One of these conditions is that the bulk drug substance appears in Category 1. As described in this guidance, FDA does not intend to categorize bulk drug substances nominated for inclusion on the 503B bulks list on or after the publication date of this guidance. However, FDA intends to consider such substances for inclusion on the 503B bulks list in accordance with the process and clinical need standard established in the FD&C Act (see section 503B(a)(2)(A)(i) of the FD&C Act). FDA is evaluating bulk drug substances nominated for the 503B bulks list on a rolling basis. Substances that appear in Category 1 (including substances nominated with adequate supporting information prior to the date of publication of this guidance) may continue to be within the scope of the policy for Category 1 substances, as described in the guidance, until FDA makes a final determination whether these substances will be placed on the 503B bulks list in accordance with section 503B(a)(2)(A)(i) of the FD&C Act or unless the Agency removes the substances from Category 1 based on, for example, information about safety risks.

Prior to preparing this guidance, FDA considered comments received on the draft guidance. Editorial changes were made to improve clarity, such as updating references to the publication date of this final guidance.

This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on the “Interim Policy on Compounding Using Bulk Drug Substances Under Section 503B of the Federal Food, Drug, and Cosmetic Act.” 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.
