Sponsors advised of transition to eCTD-only

10 November 2020

From 1 November 2021, the Therapeutic Goods Administration (TGA) will begin a staged transition to Electronic Common Technical Document-only (eCTD-only) for all prescription medicines.

This transition will see Australia adopt best practice standards that are currently applied across the world. Providing benefits for both sponsors and regulators, the use of eCTD will enhance lifecycle management and navigation ability, making this an effective solution for the compilation, tracking and evaluation of dossiers.

Transition timeline

1 November 2021 - eCTD-Only Stage 1:

  • New Chemical Entity Medicine (Type A)
  • New Biological Entity Medicine (Type A)
  • New Biosimilar Medicine (Type A)
  • New Combination Medicine (Type B)

1 June 2022 - eCTD-Only Stage 2:

  • Extension of Indications Medicine (Type C)
  • Major Variation Medicine (Type F)
  • New Generic Product (Type D)

1 November 2022 - eCTD-Only Stage 3:

  • All remaining prescription medicine data including master files

Sponsors are reminded that once you begin using the eCTD for a product, you must continue to use it for all future submissions.

What if a sponsor can't meet this timeline?

The majority of Stage 1 and Stage 2 applications are already provided to us within the eCTD format. Longer timeframes have been proposed to ensure that the mandating of the eCTD does not hinder medicines within the development pipeline.

Requests for exemptions will be considered by the TGA on a case-by-case basis if you are unable to use the eCTD format for an application.

Additional information

Guidance on how to submit data in the eCTD format is available on the Submitting data in the eCTD format page.
