#348: Considerations for IVD

Global Medical Device Podcast · 14 Dec 2023 · 36m · Episode 348

What this episode covers

Carmen Brown, regulatory and quality affairs manager at Proxima Clinical Research, explains the specific regulatory pathways for In Vitro Diagnostics (IVDs) under the FDA's CDRH. She details how IVD risk classification (Class 1, 2, or 3) depends on the consequences of false results, using examples like glucose monitors versus cancer diagnostics. Brown highlights common pitfalls in performance evaluation, particularly for multi-band diagnostics, arguing that likelihood ratios are superior to sensitivity and specificity for determining clinical utility. She also warns against the strategy of starting with Laboratory Developed Tests (LDTs) before pursuing full IVD approval, citing enforcement actions against companies like 23andMe as cautionary tales.

    154 - IVD's, LDT's, Companion Diagnostics, Precision Medicine, Clinical Validation, Biomarkers, Test Methods, Detection Limits and CLIA with Devon C. Campbell

    Devon Campbell, Founder of Prodct LLC and CPO of myBiometry, explains the regulatory and engineering distinctions between In Vitro Diagnostics (IVDs), Lab Developed Tests (LDTs), and companion diagnostics. He details how IVD development mirrors medical device design control but adds critical layers of risk management regarding false positives and negatives, particularly for home-use devices like COVID tests. Campbell emphasizes that clinical validation requires proving statistical validity across diverse populations to establish Limit of Detection (LOD) and sensitivity, noting that clinical studies are often the most time-consuming and expensive part of the process for startups.

    055 - "Critical Tasks and Knowledge Tasks" with Alexandra Benbadis

    Alexandra Benbadis, Usability Leader at Sanofi and former Senior Human Factors Consultant at Emergo by UL, explains the regulatory distinctions between critical and knowledge tasks in combination product human factors studies. She details how the FDA's CDRH and CDR definitions of 'harm' expand the scope of critical tasks to include compromised medical care, such as underdoses in maintenance medications, requiring rigorous residual risk commentary. Benbadis also describes the evolution of knowledge task protocols, specifically the two-part approach to evaluate Instructions for Use (IFU) findability and comprehension without requiring their use during initial open-ended questioning.

    202 - Becoming an Expert in the Work Nobody Wants to Do/Design, Risk, and the Messy Middle of Combination Products w/Joey Frechin

    Joey Frechin, a Senior Technical Program Manager in med tech consulting, explains the complexities of aligning risk assessments for combination products, noting that while drug and device teams are starting to integrate their processes, significant methodological gaps remain. He details the P1/P2 probability scoring methodology used in ISO 14971 to distinguish between device failure and patient harm, and shares his career strategy of becoming an expert in 'unwanted' but high-value tasks like DFMEA and PFMEA to bridge engineering and quality teams. Frechin also discusses current industry trends, where companies often pivot from complex bespoke designs to simplified or off-the-shelf subsystems to meet clinical trial timelines, highlighting the critical importance of early sterilization and accelerated aging testing to avoid late-stage failures.

    079 - How FDA Reviews Combination Products, Policy, EPR's, and Harmonization with Rumi Young

    Rumi Young, Director of Regulatory Policy at Becton Dickinson (BD), explains how the FDA reviews combination products, drawing on her previous tenure as Acting Assistant Director in CDRH’s Division of Drug Delivery. She details the inter-center consult process for products like auto-injectors and smart connected devices, highlighting the manual nature of current submissions and the critical need for clear device identification in NDAs and BLAs. Young discusses the role of industry in shaping policy, advocating for updated Essential Performance Requirements (EPRs) and international harmonization through IMDRF to address the gap between evolving technologies and outdated guidances.

    012 - "Asking then Seeing" with Sara Waxberg Mcnew

    Sara Waxberg McNew, Chief Scientific Officer at Design Science, explains the human factors process for medical devices, emphasizing the distinction between formative studies and summative validation. She details how to interpret ANSI/AAMI HE75 and IEC 62366-1 standards, manage risk for combination products, and handle regulatory submissions with the FDA. The discussion covers specific challenges like testing rare patient populations, using surrogates, and conducting threshold analyses for generics.
