Globally, medical device software must follow regulatory processes based on risk classification. The introduction of MDR represents a significant shift in risk-based classification for Medical Devices in Europe, including classification Rule 11 for software, which has caused significant discussions among European regulators. Three years after implementation, we conducted a systematic impact assessment of MDR classification Rule 11 for MDSW through a qualitative and quantitative analysis of over 2000 software entries from the European Medical Device database, complemented by data from other public databases such as the German DiGA directory and mHealthBELGIUM. Our results indicate that classification Rule 11 of the MDR results in a narrow bandwidth for class I software, whereas this used to be the most frequent classification for software under the MDD: while most of legacy software in EUDAMED falls in the lowest risk category as MDD Class I (53%), the situation reverses after the implementation of MDR with the most entries in Class IIa (55%). Analyzing the legacy MDD patient apps in Germany implies that three quarters will have to re-classify as MDR Class IIa at the end of the transition period in 2028. A comparison of the European and US regulatory landscapes, along with a systematic review of software features for Class I vs. Class IIa products, explains our findings and enables us to recommend a regulatory strategy for developing MDSW compliant with MDR Class I rules, ensuring fast access to the European market.</p>","PeriodicalId":23084,"journal":{"name":"Therapeutic innovation & regulatory science","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143060821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most health authorities no longer require comparative animal toxicology studies of the proposed biosimilar and reference product, these are still required in several countries, forcing biosimilar companies to conduct such studies or risk non-approval of their product.

Therefore, the development of a robust risk mitigation strategy, as a crucial component of comprehensive risk planning, is not just important but essential for effective drug development, particularly in the RBQM (Risk-Based Quality Management) ecosystem and its component-RBM (Risk-Based Monitoring). This emphasis on the urgency and significance of risk mitigation strategy can help the audience understand the gravity of the topic. The paper introduces a novel modeling framework for deriving an efficient risk mitigation strategy at the planning stage of a clinical trial and establishing operational rules (thresholds) under the assumption that contingency resources are limited. The problem is solved in two steps: (1) Deriving a contingency budget and its efficient allocation across risks to be mitigated and (2) Deriving operational rules to be aligned with risk assessment and contingency resources. This approach is based on combining optimization and simulation models. The optimization model aims to derive an efficient contingency budget and allocate limited mitigation resources across mitigated risks. The simulation model aims to efficiently position each risk's QTL/KRI (Quality Tolerance Limits/Key Risk Indicators at a clinical trial level) and Secondary Limit thresholds. A case study illustrates the proposed technique's practical application and effectiveness. This example demonstrates the framework's potential and instills confidence in its successful implementation, reassuring the audience of its practicality and usefulness.
