ICH: Final Q3D (R2) Guideline on Elemental Impurities

ICH Q3D (R2) has reached Step 4 of the ICH-Process and will now be distributed to the Member States for implementation. The revision (R2) focused on

  • the establishment of limits for elemental impurities by the dermal route of exposure, summarized in a new Appendix 5 Limits for Elemental Impurities by the Cutaneous and Transcutaneous Route
  • and error corrections of the PDEs for Silver (oral), Gold (oral, parenteral and inhalation) and Nickel (inhalation).

The newly established PDEs:

  • The corrected parenteral PDE for Silver is 15 μg/day.
  • The corrected PDE of Gold by oral, parenteral or inhalation routes is identified as 300, 300, 3 μg/day.
  • The corrected PDE of Nickel by inhalation is now listed with 6 μg/day.

For more details please refer to the Guideline for elemental impurities Q3D (R2), which was adopted on 26 April 2022 by the Regulatory Members of the ICH.
