• Complete clinical study reports
• Nonclinical toxicology raw data

Correct Answer: Local labeling, patient information leaflet and application forms

Q7. What best describes the eCTD standard used for electronic submissions compared with ACTD?

• An XML backbone with PDF documents enabling lifecycle management of submissions
• A paper-only dossier intended for postage to regulatory agencies
• A non-structured PDF file with no sequence management
• A proprietary word-processing format used in ASEAN only

Correct Answer: An XML backbone with PDF documents enabling lifecycle management of submissions

Q8. Why is climatic zone classification important when planning stability studies for ASEAN submissions?

• It determines the long-term and accelerated storage conditions reflecting hot and humid climates
• It defines the manufacturing temperature limits for GMP sites
• It specifies the solvent systems to be used in analytical methods
• It dictates the clinical trial eligibility criteria

Correct Answer: It determines the long-term and accelerated storage conditions reflecting hot and humid climates

Q9. What is the primary purpose of a bridging study in the context of using foreign clinical data for local ACTD submissions?

• To demonstrate that foreign clinical data are applicable to the local population and conditions
• To replace the requirement for any chemistry documentation
• To waive all pharmacovigilance obligations after approval
• To provide manufacturing batch release certificates only

Correct Answer: To demonstrate that foreign clinical data are applicable to the local population and conditions

Q10. For immediate-release oral generics submitted in ASEAN countries, which study is most commonly required to support interchangeability?

• Bioequivalence study
• Full new drug clinical efficacy trial
• Long-term carcinogenicity study in two species
• Complete pharmacokinetic modeling without in vivo data

Correct Answer: Bioequivalence study

Q11. Who is the primary authority responsible for technical review and approval of an ACTD submission within each Asian country?

• The national regulatory authority (country’s drug regulatory agency)
• The ASEAN Secretariat in Jakarta
• An appointed international contract research organization only
• A regional commercial distributor

Correct Answer: The national regulatory authority (country’s drug regulatory agency)

Q12. Which type of content is included in ACTD Module 2?

• Overviews and critical summaries of the quality, nonclinical and clinical information contained in Modules 3–5
• Detailed batch manufacturing records and raw data tables
• Country-specific application forms and labels
• Local GMP inspection reports only

Correct Answer: Overviews and critical summaries of the quality, nonclinical and clinical information contained in Modules 3–5

Q13. Which of the following is NOT part of Module 3 (Quality) of the ACTD?

• Clinical study reports
• Drug substance and drug product characterisation
• Specifications and analytical methods
• Manufacturing process descriptions

Correct Answer: Clinical study reports

Q14. Which dossier elements commonly require translation into the local language for many Asian regulatory submissions?

• Module 1 items such as the label, patient leaflet and signed application forms
• Raw chromatograms from all stability runs
• Standard operating procedures from foreign QC labs
• All Module 3 analytical method validation reports entirely in local language

Correct Answer: Module 1 items such as the label, patient leaflet and signed application forms

Q15. Which country-specific regulatory element related to post-marketing safety is typically provided in Module 1 of an ACTD submission?

• National pharmacovigilance system details and safety reporting commitments
• Complete immunogenicity raw data for biologics only
• International pricing and reimbursement approvals
• Global marketing strategies

Correct Answer: National pharmacovigilance system details and safety reporting commitments

Q16. Which statement correctly contrasts ACTD and eCTD submissions?

• eCTD is an electronic lifecycle submission standard (XML backbone) while ACTD refers to the dossier content framework often submitted in paper or electronic form
• ACTD is always electronic and eCTD is always paper
• They are identical standards with no practical differences
• eCTD is used only for clinical trials and ACTD only for manufacturing licenses

Correct Answer: eCTD is an electronic lifecycle submission standard (XML backbone) while ACTD refers to the dossier content framework often submitted in paper or electronic form

Q17. What is one of the most common causes for an ACTD submission being administratively rejected at initial filing in many Asian agencies?

• Incomplete or missing Module 1 documents such as local application forms, certificates or translations
• Too much stability data provided in Module 3
• Inclusion of clinical data in Module 3 instead of Module 5
• Using an eCTD format instead of paper

Correct Answer: Incomplete or missing Module 1 documents such as local application forms, certificates or translations
