Under Recommendation 15 of the Review of Medicines and Medical Review Regulation (MMDR) the Government agreed to greater utilisation of marketing approvals by comparable overseas regulators to support assessments of medical devices in Australia. Legislative amendments in the Therapeutic Goods Amendment (2017 Measures No. 1) Act 2018 to enact this change also included clarifications regarding preliminary assessment of applications for pre-market authorisation. This presentation will review the implementation arrangements for these changes, covering the increased options for use of overseas approvals, and the evidence requirements to support applications.
