Q3C(R8) Impurities: Guidance for Residual Solvents; International Council for Harmonisation; 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 “Q3C(R8) Impurities: Guidance for Residual Solvents.” The guidance was prepared under the auspices of the International Council for Harmonisation (ICH), formerly the International Conference on Harmonisation. This guidance provides recommendations for permitted daily exposures (PDEs) for three additional residual solvents: 2-Methyltetrahydrofuran, cyclopentyl methyl ether, and tert-butyl alcohol. The PDEs were developed according to the methods for establishing exposure limits included in the guidance for industry “Q3C: Impurities Residual Solvents” (Q3C guidance). The Q3C PDE levels are added and revised as new toxicological data for solvents become available. This guidance finalizes the draft guidance entitled “Q3C(R8) Recommendations for the Permitted Daily Exposures for Three Solvents—2-Methyltetrahydrofuran, Cyclopentyl Methyl Ether, and Tert-Butyl Alcohol—According to the Maintenance Procedures for the Guidance Q3C Impurities: Residual Solvents” issued on May 27, 2020.

DATES:

The announcement of the guidance is published in the Federal Register on December 13, 2021.

SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a guidance for industry entitled “Q3C(R8) Impurities: Guideline for Residual Solvents.” The guidance was prepared under the auspices of ICH. ICH has the mission of achieving greater regulatory harmonization worldwide to ensure that safe, effective, high-quality medicines are developed, registered, and maintained in the most resource-efficient manner. By harmonizing the regulatory requirements in regions around the world, ICH guidelines have substantially reduced duplicative clinical studies, prevented unnecessary animal studies, standardized the reporting of important safety information, standardized marketing application submissions, and made many other improvements in the quality of global drug development and manufacturing and the products available to patients.

The six Founding Members of the ICH are FDA; the Pharmaceutical Research and Manufacturers of America; the European Commission; the European Federation of Pharmaceutical Industries Associations; the Japanese Ministry of Health, Labour, and Welfare; and the Japanese Pharmaceutical Manufacturers Association. The Standing Members of the ICH Association include Health Canada and Swissmedic. Additionally, the Membership of ICH has expanded to include other regulatory authorities and industry associations from around the world (refer to https://www.ich.org/ ).

ICH works by involving technical experts from both regulators and industry parties in detailed technical harmonization work and the application of a science-based approach to harmonization through a consensus-driven process that results in the development of ICH guidelines. The regulators around the world are committed to consistently adopting these consensus-based guidelines, realizing the benefits for patients and for industry.

As a Founding Regulatory Member of ICH, FDA plays a major role in the development of each of the ICH guidelines, which FDA then adopts and issues as guidance for industry. FDA's guidance documents do not establish legally enforceable responsibilities. Instead, they describe the Agency's current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited.

In the Federal Register of May 27, 2020 (85 FR 31785), FDA published a notice announcing the availability of a draft guidance entitled “Q3C(R8) Recommendations for the Permitted Daily Exposures for Three Solvents—2-Methyltetrahydrofuran, Cyclopentyl Methyl Ether, and Tert-Butyl Alcohol—According to the Maintenance Procedures for the Guidance Q3C Impurities: Residual Solvents.” The notice gave interested persons an opportunity to submit comments. In the Federal Register of June 5, 2020 (85 FR 34638), FDA issued a correction providing that the date by which to submit comments was July 27, 2020.

After consideration of the comments received and revisions to the guideline, a final draft of the guideline was submitted to the ICH Assembly and endorsed by the regulatory agencies in April 2021.

First published in December 1997, the Q3C guidance provides recommendations on the use of less toxic solvents in the manufacture of drug substances and dosage forms and sets pharmaceutical limits for residual solvents (organic volatile chemicals) in drug products. Q3C PDE levels are added and revised as new toxicological data for solvents become available. As part of the maintenance process, the Q3C(R8) guidance provides final PDEs for three additional residual solvents: 2-methyltetrahydrofuran, cyclopentyl methyl ether, and tert-butyl alcohol. Additional information regarding supporting studies was incorporated into the guidance based on comments received, but the recommended PDEs for the three new residual solvents are identical to those published in the draft guidance issued on May 27, 2020. This guidance finalizes the guidance issued on May 27, 2020.

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 “Q3C(R8) Impurities: Guidance for Residual Solvents.” 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. Therefore, clearance by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not required for this guidance. The previously approved collections of information are subject to review by OMB under the PRA. The collections of information in 21 CFR part 58 have been approved under OMB control number 0910-0119.
