  • Whitepaper Good Identification Practices for Organic Extractables and Leachables Via Mass Spectrometry

    The function of a pharmaceutical drug product or a medical device is to provide the patient with a desired therapeutic benefit. If the drug product or the medical device were pure (meaning without impurities), ideally the therapeutic benefit would be largely realized with minimal adverse patient effects. However, since the practical reality is that drug products and medical devices contain impurities, a patient is exposed to these impurities during treatment and these impurities could potentially trigger an increase of adverse patient effects.
  • Whitepaper When Drug Meets Device...

    When a medicinal product (drug or biologic) meets a medical device, a combined product is created. Incompatibility between the components can present a danger to the patient, but how can one demonstrate the fit between a medicinal product and a device? This paper describes the relevant definitions, the existing regulatory framework for combined products (or better the lack thereof), and focuses on stability testing to assess drug or biological-device compatibility.
  • Video Nelson Labs Europe

    Nelson Labs Europe’s capabilities are complementary and additive to Nelson Labs’ existing testing portfolio and, in combination, makes Nelson Labs one of the premiere global E&L laboratory testing platforms for the pharmaceutical and medical device industries.
  • Video The Necessity of Extractable and Leachable Qualifications for Lyophilized Drug Products: Some Fallacies Addressed

    The webcast will explain the outgassingmechanism of the lyo-stoppers, which may lead to further accumulation of leachables adsorbed onto the lyo-cake. In addition, an experimental testing strategy will be explained that covers both the discovery, identification, and quantification of those leachables, as well as the formation of secondary leachables through chemical reactions between these reactive leachables and the drug product and its ingredients.
  • Video Changing Regulatory Requirements for Extractables & Leachables Testing on Pharmaceutical Packaging Systems

    In the past decade, scrutiny has changed in the way EMEA or FDA regulators look at Extractables & Leachables data. Requirements gradually increased without official guidance, which left the Pharmaceutical Industry in the dark. Second-guessing the current position and requirements of regulators to support a submission became the norm. This presentation will address the following: Key success factors of E&L projects. An understanding of what regulators want and how to meet expectations. Facing the reality of the ever-evolving regulatory landscape, analytical testing labs need to be at the forefront with expertise in the field of Extractables and Leachables testing and state-of-the-art technology. Meeting development needs and requirements for the pharma industry and raising the bar for material suppliers. Mitigating risk through successful partnering between drug product vendors, material suppliers and the CRO performing the test. This webinar originally aired as part of Pharmapack Europe 2021
  • Video Where N-Nitrosamine Assessments for Drug Products Meet Extractable / Leachable Qualifications for Pharmaceutical Primary Packaging

    Recently there have been a number of drug product recalls due to the unexpected presence of N-Nitrosamines. While in most of those cases, N-Nitrosamine formation occurred at the level of the drug substance synthesis and stability, it is well known and documented that some materials, used in primary packaging can also be a source for NNitrosamine contamination of the packaged drug product (e.g. older grade elastomers and nitrocellulose laminated blister foils). The unanswered question is: do we know everything about the materials of construction of a container closure system and their ability to generate N-Nitrosamines? This presentation will offer insights into how an integrated approach for the N-Nitrosamine risk evaluation for a pharmaceutical container closure system could look like.This webinar originally aired as part of Pharmapack Europe 2021
  • Webinar On the Origin of Extractable Species

    In this webinar, originally broadcast as part of the Pharmapack Europe show, Piet Christiaens, Scientific Director, Nelson Labs talks about the Universe of Extractables and how there are many different types of materials being used in the construct of a Container system. The impurities profile of a material is typically composed of compounds that were intentionally added to a material to protect the material during production or its life cycle or to increase performance or functionality. In this case, he is talking about polymer additives. However, there is even a longer list of compounds that are present in a material that were not intentionally added. These compounds have been introduced during the production process of the material, or they are the result of ageing of the material. The presentation will give an overview – for the most common materials used in the construct of container/closure systems or medical devices – of the main classes of compounds that are often detected in extractable studies.
  • Webinar The Necessity of Extractables & Leachables Qualifications for Lyophilized Drug Products

    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 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. When you attend this webinar, you will have: A thorough understanding of the interaction mechanisms between a lyophilized drug product and it's container. An understanding of an Extractables and Leachables study design for a lyophilized drug product
