Session I: Regulatory Standards for E&L
Session Description
This session will feature presentations exploring the ever-changing regulatory landscape in the USA.   Presentations in this session will address updates on regulations ISO standards etc.
Implementing 10993-18: Considerations in Establishing an AET for Chemical Characterization of Medical Devices
This talk will focus on the analytical evaluation threshold (AET), including its purpose and approaches to selecting it.   Of particular importance are the AET components of uncertainty factor (UF) and dose based threshold (DBT).   To this end, the 10993-18 approach to UF will be discussed, along with its limitations and views FDA reviewers have expressed.  Also presented will be the use of multiple orthogonal analytical methods/detectors as a means to potentially reduce the need for large values of UF.  Finally, issues related to setting the DBT will be explored—time permitting.
Attendees should come away from this session with some awareness of the current issues in establishing an AET for chemical characterization of medical devices, as well as a better understanding of possible approaches in this developing field

Session II: Overcoming Analytical Challenges
Importance of a High Performing Screening Method for Testing Stability Samples for Leachable Impurities
Leachable testing for finished pharmaceutical products are important part of the regulatory filing and it is under more scrutiny than ever before. Leachable testing for multiple finished drug products such biologics, large volume parenterals and polymer based finished products requires to work on a trace levels with high confident. Working with trace levels (typically 10 parts per billion or below), requires high level of analytical expertise and top of the line analytical instrumentation. Leachable testing ideally should be performed on a targeted list of analytes and a general non-targeted screening fashion, to avoid any unexpected leachables. For targeted screening analytical testing is more straightforward, and usually not an issue to detect the targets even at ppb sub-ppb level. However, for a general screening method this can be difficult, and many times requires special sample preparation combined with high resolution accurate mass detection. Case studies will be presented to show the importance of a high-performance and sensitive screening method, to detect unexpected leachables, and to support related quality investigations

The use of Solid Phase MicroExtraction (SPME) in Extractables and Leachables Studies
Common approaches to extractables studies of medical devices or combination products or pharmaceutical closure systems is extraction with a range of solvents (polar, modified polar, and non-polar). Extraction times and temperatures vary but at the end of the extractions one is left with deciding how to analyze the extracts. One of the common analytical techniques is GC/MS for volatile to semi-volatile organics. Often, to reach the desired level of sensitivity, the extracting solvents need to be back extracted (liq/liq extraction) into a different organic solvent which is then volume reduced to concentrate the analytes. An alternative approach is to use Solid Phase MicroExtraction (SPME) and then desorb the SPME fiber via the GC injection port. This has the advantage of not diluting the analytes in a solvent and thus affords superior sensitivity. We have used SPME-GCMS for various projects including, but not limited to, Extractables and Leachables. This presentation will review the SPME techniques, their advantages and disadvantages, and offer some case studies relevant to both extractables and leachables studies.

Session III: Understanding Materials Contributions to Leachable profiles
Understanding Extractables Profile from Polymerization Chemistry
Why the extractables profiles of low density polyethylene (LDPE) component and high density polyethylene (HDPE) component are so much different although both LDPE and HDPE are polyethylene? Why the extractables profile of polypropylene component are so much more complicate than polyethylene component although both are simple polyolefin material? This presentation explores the extractables profile of some common polymer materials and explains the extractables profiles from the polymerization chemistry.

Session IV: The Role of Chemical Characterization in Establishing the Biocompatibility of Medical Devices
Session Description
The process by which the biocompatibility of medical devices is evaluated is undergoing an exciting change; transitioning from an approach that largely relied on animal testing to a method that is increasingly based on the safety assessment of extractable and leachable (E&L) compounds released from the device.  The two cornerstones of this approach are the ISO 10993-18 standard on chemical characterization and the ISO 10993-17 standard on the toxicological risk assessment of medical device constituents.  These standards are currently undergoing revision and this session will provide the latest updates on the new concepts that are being considered for incorporation into the revised standards.

Extractables and Leachables in Biologics – Lessons Learned from the past 10 years
This presentation will focus on the most prominent lessons learned in relation to the assessment of extractables / leachables in biological drug products in the past 10 years, including the importance to identify clearance steps, to design extraction protocols that are well-adjusted to the actual application, and to mind scaling factors during extrapolation of extractables in the drug product, for instance. Special focus will be put on extractables and therefore, potential leachables derived from chromatography resins and leachables in solvents that are used for lyophilized drug products. Despite best efforts, an E&L assessment for biologics may still contain uncertainty. Therefore, it is important to understand the uncertainty factors that are inherent to materials, extractable testing and toxicological threshold values and to balance any remaining risk with expert judgment, data from clinical studies and pharmacovigilance and ultimately, the benefit from the treatment with the biological drug product.

Comparative Study of the Efficiency of Binary Solvent Mixtures vs Blood to Simulate the Use Condition for Medical Devices.
A significant difference in the leachables analysis of medical devices as compared to pharmaceutical packaging is the ability to utilize the actual use condition (drug product) for the analysis of pharmaceutical packaging. The use condition for many medical devices (biological environment) is difficult to simulate and therefore it has been common practice to use binary solvent mixtures (alcohol/water) to simulate the leachables condition. Recently, a number of potential concerns have been raised about the use of binary solvent mixtures such as preferential absorption of the more hydrophobic component of the solvent by the medical device. In this talk, we will review the issues related to the use of binary solvents as well as relay results showing a comparison of the extraction power of blood contrasted with saline and water/alcohol mixtures for a series of analytes relevant to blood contacting medical devices. In addition, a brief update will also be provided on the latest work on mitigating the need for uncertainty factors through a multidetector strategy as recently publications in a work entitled “An Analytical Strategy Based on Multiple Complementary and Orthogonal Chromatographic and Detection Methods (Multidetector Approach) to Effectively Manage the Analytical Evaluation Threshold (AET)

Analytical Considerations in Extractable and Leachable Studies of Medical Devices per ISO 10993-18:2020
Chemical characterization (Extractable and Leachable Studies) per ISO 10993 has become an important component of biocompatibility testing for medical devices. A major revision of ISO 10993-18 “Chemical characterization of medical device materials within a risk management process” was recently published in the beginning of 2020. This presentation will focus on the analytical considerations of medical device extractable and leachable (E&L) studies per the new ISO 10993-18 chapter. Topics to be covered will include: 1. Understand the analytical testing requirements per the new ISO 10993-18. 2. How to design an extractable study of medical devices in terms of solvent selection, extraction conditions, setting the suitable analytical evaluation threshold (AET), etc. 3. Analytical case studies per common regulatory deficiency points on medical device E&L studies, including requirements on reference standards during semi-quantitation, spiked recovery, LC-MS ionization modes, analytical uncertainty factor, compound identification status, etc.
