International scientific guidelines adopted in Australia

5 August 2020

The TGA closely aligns its regulatory approaches to therapeutic products with those of comparable international regulatory counterparts wherever possible.

Technical data requirements for applications to register or vary the registration of medicines in Australia are closely aligned with requirements set out in relevant:

  • European Union (EU) Guidelines
  • Guidelines issued by the International Conference on Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use
  • Food and Drug Administration (USA)

International Guidelines are not limited to prescription medicines, but may also apply to OTC, complementary and some listed medicines. It is important that you review the relevant guidelines that are adopted in Australia prior to manufacturing and supplying a medicine.

While guidelines that are adopted in Australia are generally not mandated by legislation, they provide guidance to sponsors to assist them to meet the legislative requirements and any deviation from a Guideline relevant to an application to register or vary the registration of a medicine must be justified.

Prior to adopting any Guideline, the TGA undertakes an extensive process of internal and external consultations to ensure the Guideline is consistent with prevailing requirements in Australia. TGA publishes a searchable list of International Guidelines adopted in Australia. Please check for current consultations on proposed guidelines for adoption in Australia.

Please note: Where EU Guidelines adopted in Australia include references to EU legislation (including EC Directives and Regulations), the requirements contained in the referenced EU legislation are not applicable to the evaluation of medicines by the TGA.

For multiple strengths of generic TDDS products, bioequivalence studies should be performed at least on the lowest and highest strengths versus the corresponding innovator products. If an applicant considers that this is unnecessary in a particular case, a justification for not submitting bioequivalence data should be submitted in accordance with the ARGPM guidance on Biopharmaceutic studies.
