IMDRF / GHTF: structure, purpose, STED and GMDN MCQs With Answer

Introduction: IMDRF / GHTF: structure, purpose, STED and GMDN MCQs With Answer is a focused quiz set designed for M.Pharm students studying Regulatory Aspects of Medical Devices. These questions review the international harmonization initiatives—GHTF (precursor) and IMDRF (successor)—their organizational structures, objectives, and roles in aligning regulatory practices globally. The set emphasizes STED (Summary Technical Documentation) principles for device submission, and the Global Medical Device Nomenclature (GMDN) used for standardized device identification. The questions blend conceptual understanding with practical regulatory application, helping students prepare for exams and real-world regulatory tasks such as classification, technical documentation, and post-market activities.

Q1. What was the primary reason for transitioning from the Global Harmonization Task Force (GHTF) to the International Medical Device Regulators Forum (IMDRF)?

• To reduce the number of member countries

Correct Answer: To create a more flexible, regulator-led platform for faster convergence

Q2. Which best describes the structure of IMDRF?

• A single global regulatory authority with enforcement power

Q5. Which section is typically included in a STED dossier?

• Corporate financial statements and investor reports
• Device description and design information, including risk analysis
• Employee training schedules
• Detailed distributor pricing agreements

Correct Answer: Device description and design information, including risk analysis

Q6. How does the STED approach benefit global regulatory submissions?

• Eliminates the need for clinical evidence entirely
• Provides a common format that can streamline reviews across jurisdictions
• Automatically grants market authorization in all IMDRF member countries
• Replaces all national regulatory requirements

Correct Answer: Provides a common format that can streamline reviews across jurisdictions

Q7. What is the Global Medical Device Nomenclature (GMDN) used for?

• Assigning tax codes to medical device companies
• Providing standardized names and codes for medical device types to support regulatory and post-market activities
• Replacing device unique device identifiers (UDI)
• Registering patents for device designs

Correct Answer: Providing standardized names and codes for medical device types to support regulatory and post-market activities

Q8. Which statement about GMDN codes is correct?

• GMDN codes provide a unique identifier for each specific manufactured device model
• GMDN codes describe generic device categories, not individual catalogue items
• GMDN codes are only used in Europe and are legally required worldwide
• GMDN codes contain clinical evidence summaries

Correct Answer: GMDN codes describe generic device categories, not individual catalogue items

Q9. Which IMDRF working group would most likely issue guidance on software as a medical device (SaMD)?

• Clinical Investigations Working Group
• SaMD or Software-focused working group under IMDRF
• Device Nomenclature Working Group only
• Pharmaceutical Quality Systems Group

Correct Answer: SaMD or Software-focused working group under IMDRF

Q10. In regulatory submissions, the STED format emphasizes traceability between which elements?

• Marketing slogans and manufacturer logos
• Design inputs, verification/validation results, and risk control measures
• Country GDP and device price
• Distribution routes and retail outlets

Correct Answer: Design inputs, verification/validation results, and risk control measures

Q11. Which of the following is NOT a typical component of post-market surveillance covered by IMDRF guidance?

• Vigilance and incident reporting systems
• Periodic safety update reports and trending analysis
• Mandatory product recalls orchestrated by IMDRF centrally
• Field corrective actions and monitoring of device performance

Correct Answer: Mandatory product recalls orchestrated by IMDRF centrally

Q12. How does GMDN assist in incident reporting and vigilance?

• By providing clinical treatment protocols
• By offering a standardized code that enables consistent identification of device types across databases
• By replacing national incident reporting systems
• By assigning regulatory approvals to each reported incident

Correct Answer: By offering a standardized code that enables consistent identification of device types across databases

Q13. Which IMDRF deliverable is most relevant for a manufacturer preparing a STED submission for a novel implantable device?

• Guidance on medical device nomenclature only
• STED guidance documents detailing required sections for technical documentation
• Guidance on tax incentives for device manufacturing
• Guidance on packaging design for retail sales

Correct Answer: STED guidance documents detailing required sections for technical documentation

Q14. Under IMDRF/GHTF principles, which party is principally responsible for compiling STED?

• The national regulatory authority
• The device manufacturer or their authorized representative
• The clinical trial investigator only
• A third-party marketing agency

Correct Answer: The device manufacturer or their authorized representative

Q15. Which is a limitation of GMDN that regulatory users should be aware of?

• GMDN contains clinical performance data for every device
• GMDN codes can be too generic and may not capture fine product-specific nuances
• GMDN automatically validates a device’s safety and effectiveness
• GMDN is free and open-source with no maintenance process

Correct Answer: GMDN codes can be too generic and may not capture fine product-specific nuances

Q16. Which IMDRF concept helps align pre-market evidence expectations across jurisdictions?

• Mutual recognition agreements for marketing approvals
• Harmonized guidance documents (e.g., STED, clinical evaluation principles)
• Global pricing policies for devices
• Unified customs regulations

Correct Answer: Harmonized guidance documents (e.g., STED, clinical evaluation principles)

Q17. When selecting a GMDN term for a product, which action is recommended?

• Choose any term at random since codes are interchangeable
• Select the most specific term that accurately reflects the primary intended purpose of the device
• Always use the most generic high-level category to avoid reclassification
• Create a proprietary GMDN code unique to the manufacturer

Correct Answer: Select the most specific term that accurately reflects the primary intended purpose of the device

Q18. Which IMDRF output would most directly help national regulators improve post-market surveillance?

• Guidance on clinical trial recruitment strategies
• Guidance and templates for adverse event reporting, trend analysis and risk-based PMS
• Standards for packaging aesthetics
• Templates for marketing brochures

Correct Answer: Guidance and templates for adverse event reporting, trend analysis and risk-based PMS

Q19. How can STED facilitate reliance or work-sharing between regulatory authorities?

• By providing a uniform, well-structured dossier that enables easier comparison and shared assessment
• By preventing any communication between regulators
• By guaranteeing faster market access without local evaluation
• By replacing national laws with IMDRF regulations

Correct Answer: By providing a uniform, well-structured dossier that enables easier comparison and shared assessment

Q20. In the context of IMDRF/GHTF guidance, what is the relationship between device classification and STED content requirements?

• Classification has no impact; STED content is identical for all classes
• Higher-risk device classes generally require more extensive STED content and evidence
• Lower-risk devices always need more clinical data than higher-risk devices
• STED only applies to non-sterile consumables regardless of class

Correct Answer: Higher-risk device classes generally require more extensive STED content and evidence
