          - [Docket No. FDA-2013-D-1156]

# 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The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Q3D(R1) Elemental Impurities.” The draft guidance was prepared under the auspices of the International Council for Harmonisation (ICH), formerly the International Conference on Harmonisation. The draft guidance revises the existing ICH guidance for industry “Q3D Elemental Impurities” and provides an updated permitted daily exposure (PDE) for the cadmium inhalation route of exposure. The updated PDE of 3 micrograms (µg)/day is based on a modifying factor approach like that used for calculating the PDEs for the cadmium oral and parenteral routes of exposure. The draft guidance is intended to correct a calculation error in the PDE for cadmium by the inhalation route of exposure. Following deliberations within the Q3D Expert Working Group, the revised calculation is based on a modifying factor approach that is consistent with the oral and parenteral PDE calculations.

# DATES:

Submit either electronic or written comments on the draft guidance by August 13, 2018 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.

# SUPPLEMENTARY INFORMATION:

## I. Background

In recent years, regulatory authorities and industry associations from around the world have participated in many important initiatives to promote international harmonization of regulatory requirements under the ICH. FDA has participated in several ICH meetings designed to enhance harmonization and FDA is committed to seeking scientifically based harmonized technical procedures for pharmaceutical development. One of the goals of harmonization is to identify and reduce differences in technical requirements for drug development among regulatory agencies.

ICH was established to provide an opportunity for harmonization initiatives to be developed with input from both regulatory and industry representatives. FDA also seeks input from consumer representatives and others. ICH is concerned with harmonization of technical requirements for the registration of pharmaceutical products for human use among regulators around the world. The six founding members of the ICH are the European Commission; the European Federation of Pharmaceutical Industries Associations; FDA; the Japanese Ministry of Health, Labour, and Welfare; the Japanese Pharmaceutical Manufacturers Association; and the Pharmaceutical Research and Manufacturers of America. The Standing Members of the ICH Association include Health Canada and Swissmedic. Any party eligible as a Member in accordance with the ICH Articles of Association can apply for membership in writing to the ICH Secretariat. The ICH Secretariat, which coordinates the preparation of documentation, operates as an international nonprofit organization and is funded by the Members of the ICH Association.

The ICH Assembly is the overarching body of the Association and includes representatives from each of the ICH members and observers. The Assembly is responsible for the endorsement of draft guidelines and adoption of final guidelines. FDA publishes ICH guidelines as FDA guidance.

In May 2018, the ICH Assembly endorsed the draft guideline entitled “Q3D(R1) Elemental Impurities” and agreed that the guideline should be made available for public comment. The draft guideline is the product of the Quality Expert Working Group of the ICH. Comments about this draft will be considered by FDA and the Quality Expert Working Group.

The draft guidance revises the existing guidance for industry “Q3D Elemental Impurities” and provides an updated permitted daily exposure (PDE) for the cadmium inhalation route of exposure. The revision was initiated following identification of a calculation error in the original text. The updated PDE of 3 µg/day is based on a modifying factor approach that is consistent with the method used for calculating the PDEs for the oral and parenteral routes of exposure.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on “Q3D(R1) Elemental Impurities.” 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. This guidance is not subject to Executive Order 12866.
