As part of this transition, Australia will adopt best practice standards currently applied worldwide. Using eCTD benefits both sponsors and regulators and will improve lifecycle management and navigation capabilities. **The transition date to eCTD will be done in the following stages:** **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 May 2023 - eCTD-Only Stage 3:** - All remaining prescription medicine data, including master files If a sponsor cannot meet the transition deadline(s), applications for waivers will be assessed by the TGA on a case-by-case basis. Most stage 1 and stage 2 applications are already submitted in eCTD format. Longer timeframes have been proposed to ensure that the mandate of the eCTD does not hinder the drugs in the development pipeline.
