Session 5: E&L case studies
Tailoring of standardised SUT/SUS extractables protocols for the First Disc Stack Single-Use Separator
Industry protocols describe the best practices for performing Extractables studies on Single Use Technologies (SUT), for example, those published by the BioPhorum Operations Group (BPOG) and the current drafts of the Unites States Pharmacopeia (USP) <1665> and <665>. However, these industry protocols do not describe testing protocols for new types of SUT, such as a Single-Use Separator Insert – which should be considered as a quite large and complex SU system.

This case study describes how E&L risk assessments were conducted for the first to market disc stack SU separator to direct testing requirements. The presentation will describe how the risk assessment process, conditions of use, industry protocols and analytical knowhow were used to successfully develop an appropriate testing strategy. The lessons and observations learnt will help support the design of E&L strategies for new large and complex types of SUT.

An impurity detected in a stability study: Did we miss anything in our E&L risk assessment?*
Extractable and leachable (E&L) testing are required to identify substances that can or will migrate into the drug substance or drug product during the manufacturing process, storage and administration to assess the risk for patients being exposed to these substances. Stability testing is required to provide evidence on how the quality of a drug substance or product varies over time. E&L testing and stability testing can be run in parallel, but the conditions and detection techniques used for screening can be different. Although stability testing focuses on the quality of the drug substance or product by investigating the degradation products, it can occur that compounds are detected which are leachables.

In this case study an unknown compound was detected during stability studies using LC-UV which could not be linked to a degradation product and was suspected to be a leachable. The question was raised if the unknown compound could be linked to extractables or leachables and if there was a potential risk for patient safety and drug product quality. E&L studies require complementary analytical techniques to screen for a wide range of compounds and the experimental design needs to be considered and stability studies can be set-up differently.

This case study shows challenges in identification when using complementary techniques and discusses uncertainty in identification of leachables.

The necessity of extractable & leachable qualifications for lyophilised drug products: some fallacies addressed
When selecting and qualifying the Primary Packaging for lyophilized drug products, one of the obvious questions is “how deep should one go into the E/L-qualification process of a lyo-container”. As the drug product is in a solid state, it is expected that the interaction between the lyophilized drug product and the components of a lyo-container will be low. This is also reflected in the USP<1664> Monograph on Leachables and the EMA Guideline on “Plastic Immediate Packaging Materials” (2005). However, the mechanism of interaction between the lyo-cake and e.g. the rubber stopper (when considering a lyo vial) are not always fully understood. The interaction mechanism is based upon “outgassing” of the rubber stopper, where the lyo cake acts as an adsorbent. Not only can this lead to substantial accumulation of the volatile and semi-volatile leachable compounds onto the lyophilized drug product, it may also induce chemical reactions between the leachables and the drug product, i.e. when the adsorbed leachables show electrophilic properties.

Comprehensive use of high-resolution accurate mass LC/MS analysis in leachable studies*
According to USP <1664>, the analytical methods used for leachables studies 'must be subject to complete validation using industry-accepted validation practices' as well as 'capable of characterizing targets as well as new (or unspecified) leachables'. This requires validated LC/MS methods for quantification of specified targets which have been detected in the previously performed extractables study. This presentation will demonstrate the benefits and advantages of high-resolution accurate mass LC/MS in leachables studies in order to obtain comprehensive quantitative and qualitative information about the studied formulation.

Qualitative extractable and leachable testing
The initial determination of extractables compounds is often done by high resolution mass spectrometry using ToF MS in Information Dependent Acquisition (IDA) mode. If compounds are present at low levels, or chromatographically coelute with other compounds, they may be missed. Here we present a SWATH acquisition method, that when coupled with an extractables and leachables focused compound library, will provide greater confidence that extractable compounds are not missed during analysis. Extractables samples were prepared using different conditions specified in the USP guidelines. A ExionLC system (SCIEX) with a Phenomenex 150x2.1mm, 1.6u Luna Omega C18 column was used for separation. Data was acquired on a X500R QTof system (SCIEX) operated in SWATH mode, scanning from 100 to 1100 m/z. Data was using both targeted library searching and non-targeted peak finding. The MS/MS library contains high resolution, full scan spectra for compounds known to be present in many types of packaging and handing materials. The ability to compare high resolution MS/MS spectra for acquired data with library spectra for known compounds added confidence to identification.
