ACTD (ASEAN Common Technical Dossier) is a dossier for marketing authorization of Pharmaceutical / Biologicals / biotechnical products in ASEAN region. ACTD is essentially divided into 4 parts. Each part provides information under specific head.
Part I of ACTD provides admin and brief product information
Part II of ACTD provides Quality related information on the drug substance and drug product.Out of all the parts, the part II is most important. In this one section is completely devoted to QOS and another section is devoted to detailed data on drug substance and drug product. This part not only evaluates technical suitability of the product but also determines the suitability of active drug and Excipients. It consists of 4 distinct parts named e.g. as Part1, Part 2, Part 3 and Part 4.
Part III of ACTD provides nonclinical profile of the product and Part IV of ACTD provides clinical profile of the product For generic products the most important part is Part II. The part III is virtually not required. The part IV is required to the extent applicable to BE studies.

The designing of ACTD Quality Part is not as easy as it looks. The ASEAN region requires proper information strictly as per the index based on actual experimentation. Data fraud is strongly discouraged.The incomplete, unwanted, falsified information is not entertained for registration. The last but not least the information need to be presented in easily readable format with proper margins, font size and font type.
For the marketing authorization of the drug products ACTD the technical documents subdivided 4 parts is essential. The part 2 is a very critical part of the submission. The information on both the drug substance part and the drug product part shall be included in this part as detailed above.
