CTD and eCTD format MCQs With Answer

CTD and eCTD Format MCQs With Answer helps M. Pharm students build a strong, practical understanding of global dossier structure and electronic submissions in Regulatory Affairs. The Common Technical Document (CTD) harmonizes quality, nonclinical, and clinical data presentation across ICH regions, while the electronic Common Technical Document (eCTD) standardizes digital submission, lifecycle management, and review. This quiz focuses on key concepts such as module content, granularity, lifecycles, Study Tagging Files, backbone structure, validation, and regional differences. The questions are designed to test applied knowledge relevant to regulatory submissions like NDA, ANDA, and MAA, ensuring students can navigate dossier organization, metadata, and technical requirements that drive efficient, compliant regulatory processes.

Correct Answer: Module 5

Q9. In eCTD v3.2.2, which set of lifecycle operators is correct?

• create, modify, close, reopen
• add, update, archive, purge
• new, replace, delete, append
• submit, validate, publish, lock

Correct Answer: new, replace, delete, append

Q10. What is the primary purpose of Study Tagging Files (STFs) in eCTD v3.2.2?

• To encrypt clinical datasets for secure transmission
• To tag and organize study-level documents in Modules 4 and 5
• To generate automated reviewer guides
• To replace the regional XML envelope

Correct Answer: To tag and organize study-level documents in Modules 4 and 5

Q11. Which statement about eCTD sequence numbering is correct?

• Sequences use four-character alphanumeric IDs that may repeat
• Sequences are four-digit, zero-padded integers that increment (e.g., 0000, 0001, 0002)
• Sequences reset to 0000 after each major update
• Sequences are dated strings generated by the agency

Correct Answer: Sequences are four-digit, zero-padded integers that increment (e.g., 0000, 0001, 0002)

Q12. What is the preferred file format for narrative documents in CTD Modules 2–5 in eCTD?

• Text-searchable PDF
• Native DOCX only
• HTML only
• Executable files with embedded media

Correct Answer: Text-searchable PDF

Q13. Where should the cover letter be placed in the eCTD?

• Module 1
• Module 2
• Module 3
• It does not belong in the eCTD

Correct Answer: Module 1

Q14. Which statement best differentiates eCTD from NeeS?

• Both use the same XML backbone and lifecycle operations
• eCTD uses an XML backbone and lifecycle metadata; NeeS is a static PDF-based structure without lifecycle control
• Neither requires bookmarks or hyperlinks
• NeeS supports regional envelopes; eCTD does not

Correct Answer: eCTD uses an XML backbone and lifecycle metadata; NeeS is a static PDF-based structure without lifecycle control

Q15. Which is an example of correct CTD granularity for Modules 4 and 5?

• Combining all clinical study reports into a single PDF
• One file per study report, with appendices as separate files where appropriate
• Splitting a single study report into one file per page
• Embedding all study data within the Module 2 clinical overview

Correct Answer: One file per study report, with appendices as separate files where appropriate

Q16. Which statement about hyperlinks and bookmarks in eCTD PDFs is correct?

• External hyperlinks to websites are preferred over internal links
• Bookmarks should reflect the document’s heading hierarchy; hyperlinks should be internal and use relative paths
• Bookmarks are optional for documents longer than 50 pages
• Hyperlinks must point only to Module 1 documents

Correct Answer: Bookmarks should reflect the document’s heading hierarchy; hyperlinks should be internal and use relative paths

Q17. What is the likely regulatory outcome if an eCTD submission fails high-severity technical validation rules?

• The agency silently corrects the errors and proceeds
• The submission is delayed with no notification
• Refuse-to-file/receive or rejection until the deficiencies are resolved
• No impact as long as scientific content is complete

Correct Answer: Refuse-to-file/receive or rejection until the deficiencies are resolved

Q18. What is a “baseline” sequence in eCTD?

• A sequence that contains only administrative forms
• An initial sequence with legacy content re-submitted to establish a complete electronic dossier without changing content
• A sequence used only for withdrawals
• A sequence containing final labeling only

Correct Answer: An initial sequence with legacy content re-submitted to establish a complete electronic dossier without changing content

Q19. Which statement about regional metadata in eCTD is correct?

• Submission metadata is captured only in Module 2
• Regional XML (e.g., us-regional.xml or eu-regional.xml) carries envelope metadata like submission type and sequence
• Metadata is stored exclusively inside PDFs
• There is no regional metadata in eCTD

Correct Answer: Regional XML (e.g., us-regional.xml or eu-regional.xml) carries envelope metadata like submission type and sequence

Q20. Which is a correct high-level difference introduced with eCTD v4.0 compared to v3.2.2?

• v4.0 removes XML and uses only PDF bookmarks
• v4.0 is based on the HL7 RPS model and replaces STFs with structured study-level metadata
• v4.0 eliminates lifecycle operations
• v4.0 mandates video files for all nonclinical studies

Correct Answer: v4.0 is based on the HL7 RPS model and replaces STFs with structured study-level metadata
