In order to mitigate the risks of potentially harmful substances leaching from contact materials or process tubing into a medicinal/pharmaceutical product which may present a health risk to the patient, a robust approach to extractables and leachables (E&L) studies is required in order to gain a good understanding of the materials in the tubing products. In this short article, our expert, Dr Tino Otte, Senior Scientific Consultant, describes the steps of a rigorous E&L study that can be taken to ensure safe and high-quality materials and tubing products

The significance and challenges of delivering a biologic drug to the lungs and the nose.
Inhaled biologics have been forecast to grow in importance due to the fact that inhalation presents a highly attractive route for the administration of various classes of large molecule, particularly for the treatment of respiratory diseases. Here, Chris Vernall, Business Development Director, Intertek Pharmaceutical Services, discusses the significance and difficulties of biologics in the inhalables sector, and how Intertek’s Centre of Excellence for Inhaled and Nasal Biologics provides valuable services for those developing products in this area.

Nebuliser delivery of drugs offers a patient-friendly means of transforming a medicine into a breathable aerosol. They offer the advantage, over other types of inhaled device (such as pMDIs or DPIs), in that they do not require such strict patient coordination between inhalation and actuation, and so they are effective for the treatment of paediatric, elderly, ventilated and sedated patients.
Intertek Melbourn have been supporting clients’ product development for nearly 30 years across all classes of inhaled and nasal delivery technologies including nebulised therapeutics. In this bite-sized article our Formulation and Manufacturing Lead, David Ward, shares some considerations for successful development of nebulised drugs.

With a focus on bioequivalence testing in the development of generic inhalables, Mark Parry, Technical Director, Intertek Melbourn, highlights some of the shortcomings of aerodynamic particle size distribution and delivered dose testing, and introduces newer testing techniques that Intertek offers to allow its clients to de-risk clinical studies or even to support robustly in vitro data submissions as to avoid clinical work.

 The phenomenon of glass delamination is a serious quality issue. Delamination is characterised by the formation of small glass flakes, also known as lamellae, which are shed from the internal surface of the glass container, pH changes and extraction of ions from the glass material leaching into the product – all of which have significant potential to compromise product quality whilst also compromising the overall glass structure.

This white paper summarises testing approaches (such as USP<1660>), predictive screening studies, interaction studies, leaching experiments and microscopy investigations which can help to mitigate the risks which glass delamination pose to product quality and patient safety.

Transdermal delivery patches often contain multiple materials, adhesives and inks which increase the risk of unwanted leaching of potentially harmful substances from these materials. Such substances may penetrate the skin barrier and into the patient. For this reason, strategically designed extractables and leachables (E&L) studies are of critical importance to the development of transdermal delivery products.
In this application note, Dr Tino Otte, Senior Scientific Consultant, Intertek Reinach, describes the steps required to implement and adapt an E&L study design for a transdermal delivery patch device.

Inhaled and nasal delivery platforms have specific applications outside of their traditional uses for asthma/chronic obstructive pulmonary disease (COPD) and seasonal rhinitis/sinusitis: They can offer real advantages for the delivery of therapeutic biologics. During this short presentation, Intertek's Technical Director, Mark Parry, will provide an overview of currently available technologies and successfully marketed products, with a look at the development challenges that might be encountered — and the solutions that are available — when formulating these delivery routes. Mark will also describe key considerations when rapidly repurposing existing products for inhaled delivery.

To ensure patient safety, precise knowledge about potential contamination associated with a drug product container closure systems (CCS) or single use process equipment is critical. As the complexity of materials and construction of CCS or process equipment increases, the risk of leachables being introduced as drug impurities increases significantly. Authorities are focused on accurate determination of leachables present in the real drug matrix and this demands the need for sensitive and robust analytical effort and interpretation of complicated complicates data.
During this presentation, our expert, Dr Tino Otte, Head Consulting at Intertek in Switzerland, focuses on how to design a robust extractables and leachables study design which covers all necessary steps to meet regulatory expectations whilst highlighting potential challenges of such a study with strategies and examples of how to address these challenges.

This video describes Intertek's GMP Cryo-TEM Services supporting the development of safe and effective advanced therapies.

In this webinar, our expert, Dr Tino Otte, Head Consulting at Intertek in Switzerland, discuss extractables and leachables studies which have been performed on multiple product types and contact materials. With increasing focus by the authorities on the accurate determination of leachables in real formulations, one of the biggest challenges is to differentiate between matrix related degradation products and real leachables from the packaging or contact materials. Typical examples and case studies will illustrate how, through a strategic approach, it is possible to differentiate between the two. Furthermore, these case studies will illustrate why it is important to analyse leachables in the actual formulation and not only in extraction solutions.

The characterization and quantification of impurities in pharmaceutical products is a critical part of quality control. In many cases, routine analysis techniques are not sufficient to fully characterize the impurity profile due to overlapping of peaks, low peak intensity or inaccurate mass detection. Even if the correct molar mass of a compound is known, multiple structures are still possible and the real concentration often cannot be detected due to absence of chemically similar standards. In this webinar, our expert speaker Sandro Laiso we will highlight different approaches to characterize impurities in pharmaceutical products, step by step, making use of unique combinations of analytical techniques such as PRE-LC, HR-MS or qNMR. 

Delivery to the lungs is important for COVID-19 and there is currently an unprecedented need to accelerate development of effective therapies and vaccines. There is a focus on repurposing existing candidates as a strategic route to get the products to patients faster, however, many candidates are not yet in a format suitable for delivery to the lungs. Redevelopment must be fast, effective and accurate with tight control over quality in order to get a drug ready for clinical trials. In this webinar, Mark Parry, Technical Director, Intertek Melbourn, describes the strategies required for rapid repurposing for inhaled delivery, discussing considerations whilst mitigating anticipated challenges.

Structure elucidation and quantification of unknown species is one of the biggest challenges during development of analytical methods for routine quality control. The advantage of the NMR is the relatively simple and robust sample preparation combined with unique selectivity which often differs from those of chromatographic techniques. In many cases, matrix components and target species will show NMR signals with opposite shifts which enables the characterization of the targets directly in the sample mixture. In this webinar, we will explain how quantitative NMR can be used as a powerful tool for characterization of isolated unknowns or even complex mixtures of different compounds. Our expert will explain the advantages of the NMR method in detail with typical examples from routine analysis.

To ensure patient safety, precise knowledge about potential contamination associated with medical device materials is critical. For this reason, a robust chemical characterization is the first and mandatory step of any biocompatibility study which is performed according to the most recent version of the ISO 10993 guidance. With increasing complexity of medical devices and combination products, the risk of leachables being introduced into the body increases significantly. Depending on the type/class of device, application scenario and contact time, extractables and leachable studies can be divided in different sub-steps to build a comprehensive understanding of the related risks. 
During this webinar, our expert, Dr Tino Otte, Head Consulting at Intertek in Switzerland, will provide an analytical strategy for e/l screenings with a focus on the problems which may occur when targets above the analytical evaluation threshold are detected.

Structural integrity of protein-based therapeutics is one of the major challenges in the biopharmaceutical industry where multiple factors such as the stability, efficacy and shelf life could be affected following minor changes in manufacturing process. Multiple biophysical methods employing spectroscopic and calorimetric tools can be used for analysing Higher Order Structure (HOS). This presentation from Intertek’s biophysical expert, Anshuman Shukla, details different biophysical techniques, their application and usefulness in a regulatory setting.

Vaccines represent a diverse class of products within the pharmaceutical industry. All are complex and present their own unique challenges not only in production but in the design and implementation of strategic characterisation and quality control programs. The highest levels of safety and efficacy should be ensured through application of phase specific validated analytical methods.


In this webinar, our expert, Ashleigh Wake, describes how to build strategic quality control programs, with a focus on mRNA and DNA-based vaccines, which are product and phase specific covering the need for specialist, bespoke analytical approaches for these highly complex products.

In this webinar our expert discusses our HEK293 and E.Coli  Residual DNA quantification assays comparing a quantitative PCR (qPCR) approach with a more recent digital droplet PCR (ddPCR) technique in terms of sensitivity and reproducibility as well as discussing technical challenges.

Antibody-based Therapeutics N-linked glycosylation is a common post-translational modification on many antibody-based therapeutics, and has been linked to safety, stability and activity. Modification should therefore be monitored and controlled.


During this webcast, our expert Michael Walker discusses peptide mapping and middle-up mass spectrometry as characterization techniques that give relative levels of different glycoforms at specific sites, and compares to more common methodologies of enzymatic stripping and fluorescent labelling.
