Reformulating Drug Products That Contain Carbomers Manufactured With Benzene; 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 final guidance for industry entitled "Reformulating Drug Products That Contain Carbomers Manufactured With Benzene." The purpose of this guidance is to provide recommendations to applicants and manufacturers on what tests should be performed and what documentation should be submitted or available to support the reformulation of drug products that use carbomers manufactured with benzene. Certain United States Pharmacopeia (USP) carbomer monographs currently allow for unacceptable levels of benzene, which raises safety concerns. FDA has requested that the USP omit (or remove) these monographs, and applicants and manufacturers may need to reformulate their drug products to avoid use of these carbomers. This guidance provides recommendations for tests and documentation related to reformulation based on various routes of administration and dosage forms of affected drug products, and provides recommendations for application holders on the appropriate submission types to notify the Agency of reformulation changes. The intended effect of this guidance is to, as appropriate, provide a less burdensome risk-based approach to reformulation submissions relative to existing guidances on scale-up and post-approval changes (SUPAC), and address the immediate public health need to expedite the discontinuation of the use of carbomers manufactured with high levels of benzene in drug products.
DATES:
The announcement of the guidance is published in the Federal Register on December 28, 2023.

SUPPLEMENTARY INFORMATION:
I. Background
FDA is announcing the availability of a guidance for industry entitled "Reformulating Drug Products That Contain Carbomers Manufactured With Benzene." FDA is issuing this guidance consistent with its good guidance practices (GGP) regulation (§?10.115 (21 CFR 10.115)). The Agency is implementing this guidance without prior public comment because it has determined that prior public participation is not feasible or appropriate (§?10.115(g)(2) and (3)). FDA made this determination because benzene is a known human carcinogen, and the Agency seeks to facilitate the transition away from using carbomers manufactured with high levels of benzene. Publishing this guidance without prior public comment addresses the immediate public health need to expedite the discontinuation of the use of these carbomers and provides a less burdensome risk-based approach to applicant submissions, relative to existing guidances on SUPAC. Although this guidance document is immediately in effect, it remains subject to comment in accordance with FDA's GGP regulation.
The purpose of this guidance is to provide recommendations to applicants and manufacturers on what tests should be performed and what documentation should be submitted or available to support the reformulation of drug products that use carbomers manufactured with benzene. Certain USP carbomer monographs currently allow for unacceptable levels of benzene, which raises safety concerns. FDA has requested that the USP omit (or remove) these monographs, and applicants and manufacturers may need to reformulate their drug products to avoid use of these carbomers.
Carbomers are a group of polymers composed of acrylic acid. They are widely used as inactive ingredients in drug products as fillers, emulsifiers, gelling agents, and binding agents. There are carbomers currently used as inactive ingredients that are manufactured using benzene as a polymerization solvent. Benzene is a known human carcinogen. As such, both the International Conference for Harmonisation (ICH) guidance for industry entitled "Q3C-Tables and List" (available at https://www.fda.gov/media/133650/download ) and USP General Chapter <467> "Residual Solvents" designate benzene as a Class 1 solvent ( i.e., solvents that should be avoided) and recommend that benzene should not be employed in the manufacture of drug substances, excipients, and drug products. However, there are still several grades of carbomers that are manufactured using benzene as a solvent being used in pharmaceutical products even though alternative grades of carbomers are available that are manufactured without the use of benzene.
At the time of publication, carbomers manufactured with benzene may fall under the United States Pharmacopeia-National Formulary (USP-NF) monographs Carbomer 934, Carbomer 934P, Carbomer 940, Carbomer 941, or Carbomer 1342. These monographs permit benzene levels as high as 5,000 parts per million (ppm), which is significantly higher than the limit of 2 ppm on benzene as an impurity in the USP-NF Carbomer Homopolymer, Carbomer Copolymer, and Carbomer Interpolymer monographs. To avoid confusion, and because of the safety concerns associated with these unacceptable levels of benzene permitted by these monographs, FDA has asked the USP to remove (or "omit") the Carbomer 934P, Carbomer 940, Carbomer 934, Carbomer 1342, and Carbomer 941 monographs from the USP-NF compendium.
The guidance represents the current thinking of FDA on "Reformulating Drug Products That Contain Carbomers Manufactured With Benzene." 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.
II. Paperwork Reduction Act of 1995
While this guidance contains no collection of information, it does refer to previously approved FDA collections of information. The previously approved 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. 3501-3521). The collections of information in 21 CFR part 314 pertaining to the submission of new drug applications have been approved under OMB control number 0910-0001. The collections of information in 21 CFR parts 210 and 211 pertaining to current good manufacturing practice requirements have been approved under OMB control number 0910-0139.
