How to Manage Software as a Medical Device (SaMD) Technical Files with MDR and FDA?
Navigating the regulatory labyrinth for Software as a Medical Device (SaMD) is fraught with complexities.
It's about precision and compliance. To align with the Medical Device Regulation (MDR) in the European Union and the Food and Drug Administration (FDA) requirements in the United States, developers must construct a meticulous technical file or dossier. This document, a compendium of evidence demonstrating safety, quality, and efficacy, is paramount. Without it, Market access remains firmly out of reach, clinging to a thread of regulatory limbo.
What is the technical file in MDR and FDA context?
The technical file—or technical documentation under the European Union's Medical Device Regulation (MDR)—serves as a comprehensive dossier, encompassing all aspects of a medical device. For Software as a Medical Device (SaMD), this entails detailed records of the design, development, and performance, underscoring its safety and compliance with the stringent requirements set forth by the MDR.
In the FDA parlance, equivalent documentation for SaMD falls under "Device Master Records" (DMR) and "Device History Records" (DHR). While DMR contains the recipe for producing a device, including software specifications, DHR comprises the production history of each device. It is incumbent on developers to ensure that their documentation under the MDR or the FDA faithfully delineates the intricacies and compliance of their software, critical for securing market access and maintaining post-market surveillance.
Purpose and documents in the technical file
The raison d'être of the technical file is to substantiate SaMD compliance. It encapsulates development processes and product safety evidence within stringent regulatory frameworks.
Pivotal documents constitute the file, such as Risk Management Files and Clinical Evaluation Reports, mirroring the lifecycle stages of the SaMD. Fuse solutions like MatrixRequirements integrate these items to ensure documentation integrity.
Clear demarcations are imposed between the FDA's DMR and DHR, and MDR's Technical Documentation. The latter's breadth extends further to encompass Post-Market Surveillance and Vigilance data pertinent to SaMDs.
Navigating the MDR involves collating the General Safety and Performance Requirements (GSPR) annex, along with harmonized standards and Common Specifications. Each piece fortifies the technical file's foundation.
Strategic tooling with platforms like MatrixRequirements optimizes this information cascade. It ensures technical file completeness and facilitates a seamless audit trail for both MDR and FDA inspections.
Differences in the documents, the naming and the content between MDR and FDA
Under the MDR, comprehensive Technical Documentation is necessary, compared to the Design History File (DHF) and Device Master Record (DMR) required by the FDA. The naming conventions reflect divergent regulatory frameworks, underscoring distinct compliance pathways.
The FDA specifies the content in design controls under 21 CFR 820.30. The MDR requires a Technical File or Technical Documentation per Annex II and III.
MDR's Technical Documentation demands a General Safety and Performance Requirements (GSPR) checklist, while the FDA's DHF emphasizes design inputs, outputs, verification, and validation activities. The scope of documents needed and specificity of content can be markedly different, reflecting each agency’s focus on the lifecycle of SaMD.
Pertaining to content, there's an expectation of demonstrating clinical evaluation and performance, monitored through post-market activities under the MDR, which is analogously conceptualized through the FDA's post-market surveillance requirements. However, the depth and manner of evidence collection may vary, as MDR tends to be more prescriptive in post-market clinical follow-up expectations. This influences the nature of the documents such as Clinical Evaluation Report (CER) in the EU and Summary of Safety and Clinical Performance (SSCP), and can lead to differences in the technical file's structure and contents.
