Hi, TGA EP are similar to MDD ER. The base is GHTF document. If you did gap analysis between MDD ER a MDR GSPR, you can the results apply also for TGA EP.
The intention is still the same, to have product which is safe, effective and in regulatory compliance, but GSPR are more risk oriented and more specific. If you meet GSPR you yould be in compliance also with TGA EP (if country specific requirement are met).
