    Navigating Biocompatibility in Early Feasibility Studies

    In this episode of NAMSA’s BiocompCHATibility Podcast, our hosts discuss early feasibility studies and the scope of biocompatibility necessary to get started. They highlight the importance of controlling device response in a small patient group and how this approach shapes biocompatibility considerations within the framework of risk management. “The control measure of just having a few patients is definitely used as a reason why, in part Biocompatibility doesn't need to be as extensive as it needs to be for a pivotal where you have hundreds of people and commercialization where you lose practically all control.” – Don Pohl “I want to make sure I'm choosing materials that I can support in my plan that I know have a general knowledge of safety.” – Sheri Krajewski “There's no specific guidance that tells you what you have to do in terms of testing and what you don't, but the concept is you're going to creep up on everything you'll do. You'll do some biocomp for early feasibility.” – Don Pohl Key Discussion Points: Crafting a dynamic biological safety plan that evolves over timeEstablishing a robust evaluation strategy from the beginning to prevent missing important tests laterDesigning studies for high-risk cardiovascular implants and the importance of addressing biocompatibility and safety concerns

    Exploring Equivalency in Biocompatibility

    n this episode of NAMSA’s BiocompCHATibility podcast, we welcome back Dr. Phil Smiraldo (Principal Toxicologist, NAMSA) for his third appearance as an honorary host. The discussion centers on the complexities of equivalency in biocompatibility, examining how equivalency can range from simple to complex and how a predicate device does not always equal equivalency. Listen in as we explore these topics with Dr. Smiraldo and gain insights into the intricate world of biocompatibility and the challenges faced when trying to establish equivalence between medical devices.   “The world of equivalency runs the spectrum from incredibly simple to probably way too complex.” – Don Pohl “When we do these types of extractions on, we'll say prior devices and change to device, we're going to have variability within our experiments.” – Phil Smiraldo “You know whether you call it an equivalency assessment or change control assessment. Whatever you want to call it, I mean [10993] part one tells us if there's a change, you have to evaluate it.” – Don Pohl “I guess long story short, you could theoretically go through this whole exercise and end up with the two devices that are equivalent from a systemic toxicity perspective and that's it.” – Phil Smiraldo  Key Discussion Points Importance of confirming identical materials of construction, device categorization, and the IFU to ensure that the device remains equivalentThe detailed process required to establish proof of equivalenceThe critical role of adhering to standards in biocompatibility assessments

    Chemistry with the MFDS

    In this episode, our hosts are joined by Charles Ducker, PhD (NAMSA's Senior Director of Analytical Services) who recently returned from Korea, where he provided training to the MFDS (Ministry of Food and Drug Safety) about ISO 10993-18. Throughout this discussion, we review the use of the standard and how it is adopted by Korean authorities. We also explore the challenges that lie ahead for device developers and testing labs. “I think they [MFDS] were maybe surprised at the complexity. Laying out the information you have on your materials and the knowledge that you already have that may not lead to doing testing.” – Dr. Charles Ducker “They were interested in how to apply ISO 10993-1 and how you apply ISO 10993-18 to the standard. And they want to know how to assess whether a laboratory has conducted the test appropriately.” – Dr. Charles Ducker “One of the things I thought was very interesting… around Part 18, was what is different now versus the outdated version, and what changes came about. We had a lot of discussion about what is required and one of the big ones was AET [Analytical Evaluation Threshold] and how we calculate it.” – Dr. Charles Ducker “Also, about how we qualify methods, what components go into that and what data you have to have behind the scenes to support the fact that your methods are appropriate for the intended use.” – Dr. Charles Ducker Topics include: Korea’s current position with the use of ISO 10993-18Qualification of a laboratory for chemical characterization testingSolvents and temperatures, and the justifications for each

    New FDA Biocompatibility Guidance – Let’s Discuss

    On the latest installment of the BiocompCHATibility podcastis episode, our hosts are joined by Dr. Phil Smiraldo for his third feature3-peat episode on the podcast. The conversation throughout this episode focuses and we discuss on the new recently published FDA biocompatibility guidance document —issued onn September 7, 2023. “My favorite nuance is that annex A has slightly been updated because now the X’s and O’s are almost all gone.” – Don Pohl “Of these materials, you touch them every day, and your clothes are made out of them... Why would we need to do biocompatibility testing as a device? At a high level, that is what [(Attachment G)] says.” – Don Pohl “There are a few caveats, such as devices made for neonates… they are going to want to see the data. And similar type wording for pregnant woman.” – Phil Smiraldo “We are not saying it’s never possible, but you’re going to have to really convince us if you only look at Part 1 and not our guidance” – Sheri Krajewski-Bibins “One thing that I do like about this FDA document is it uses the same language from the ISO 10993 series.” – Phil Smiraldo Discussion points include: Verbiage updates to legally market devices and the fineprint.The Addition of Appendix G and how it can be utilized.A general overview of other changes by the FDA from their previous document.

    What Exactly is my Test Article?

    In this episode, Dr. Phil Smiraldo (NAMSA’s Senior Toxicologist) joins us to discuss the test article and the many challenges with identification and preparation. Throughout this discussion, we explore the many different types of test articles and help define what is considered patient contact and what is not? We also review how you can best work with your laboratory to define your test article preparation and make certain the test article definition is clear to the regulatory agency Listeners can expect to learn: How to easily define their test articleKey points to consider when separating patient contacting and non-patient contacting devicesThe risks of including non-patient contacting components in an extract “One of the things we thought we’d elaborate on today is how do I define my test article.” -Sheri Krajewski “We are not going to jump into the GLP regulations and jump into that definition, but we will help define the test article as it relates to biocompatibility.”– Don Pohl “I’ve even worked through a scenario for a particular device where the customer in fact came onsite to help take it apart.” – Phil Smiraldo “This stuff [prep instructions] needs to be written down clearly so anyone can follow.” – Don Pohl
