🇱🇻 Submissions in Latvia under MDR
This article provides a structured overview for MR-scientists on how to prepare and where to submit the required documents for a medical-device clinical investigation in Latvia — including studies using non-CE-marked pulse sequences and/or non-CE-marked RF coils.
Authorities to Submit To
In Latvia, “Requests for authorisation of a clinical investigation” must be made to both:
- State Agency of Medicines (Zāļu valsts aģentūra, ZVA) — Competent Authority for authorising clinical investigations of medical devices.
- Central Medical Ethics Committee (CMĒK) / institutional Research Ethics Committees (e.g., RSU Research Ethics Committee) (Ethics).
Both approvals are required before starting the investigation.
Key Documents Required
The required documents can be divided in 5 groups:
1. Application Forms
- MDR Clinical Investigation application to the Competent Authority (ZVA).
- When the EUDAMED CI/PS module is required in Latvia, submit in EUDAMED.
- Cover letter summarising device, investigational components (non-CE sequence/coil), sites, participants, timelines.
2. Clinical Investigation Documentation
- Clinical Investigation Plan (CIP) — MDR Annex XV format.
- Investigator’s Brochure (IB) — device/system description (scanner + software + coil + sequences), risk profile, MR-specific precautions.
- Risk Management File (ISO 14971), Monitoring Plan, CRFs, AE/SAE reporting procedures.
3. Safety and Performance Evidence (MR-specific)
- IEC 60601-2-33 rationale for MR environments (SAR/local SAR limits; simulations and phantom measurements).
- RF coil dossier (manufacturer ISO 13485 certificate, coil-file, FDTD/Sim4Life B1+/SAR simulations, phantom thermometry, safety report).
- Sequence safety (vendor statements that scanner safety controls remain active; watchdogs/limits; access controls to prevent accidental use).
- Best practices (e.g., ISMRM recommendations for experimental RF hardware) referenced in IB/annexes.
4. Regulatory and Legal Documents
- Insurance certificate covering participants in Latvia.
- EU Authorised Representative (if sponsor is outside the EU).
- Data protection: GDPR compliance statement and (where applicable) DPIA.
5. Ethics Committee Package (CMĒK / Institutional RECs)
- PIS & ICF (languages per CMĒK / institutional REC requirements), privacy wording aligned to GDPR.
- Recruitment materials (flyers/posters).
- Investigator CVs & GCP certificates, site suitability, institutional permissions.
Submission Pathway
- Competent Authority (ZVA): submit the full MDR clinical investigation dossier via the national process; when mandated, use the EUDAMED CI/PS module.
- Ethics (CMĒK / institutional RECs): submit the ethics dossier per the responsible committee’s forms and guidance (e.g., RSU REC).
Note: Latvia’s national rules set out procedures for device clinical investigations and ethics opinions; CA and Ethics timelines may proceed in parallel.
MR-specific notes for studies using non-CE sequences and/or non-CE RF coils
- Define the investigational device system clearly (CE-marked scanner/software + investigational coil/sequence package) and state risk class in CIP/IB.
- Evidence package: B1+ maps, SAR/local-SAR analyses, worst-case duty-cycle temperature estimates, phantom thermometry at hotspot locations (e.g., eye and cortical regions).
- Operational controls: show that scanner SAR/gradient watchdogs remain active with investigational components; document password-protected access and prevention of accidental use.
- Standards mapping: cross-reference IB/CIP evidence to IEC 60601-2-33 and your applicable standards list; cite ISMRM RF-hardware safety recommendations.
