Cambridge Healthtech Institute’s 4th Annual
Extractables and Leachables
Protecting Quality of Biologics by Ensuring Safety and Compatibility
January 21-22, 2016


In biopharmaceutical development and manufacturing, containers, drug combination products, and even disposable equipment may leach chemicals into the product that can pose significant risks to product quality and potentially compromise the stability, safety and efficacy of the biotherapeutics. The 4th Annual Extractables and Leachables (E&L) conference brings together industry experts and thought leaders to share their insights on latest updates and guidelines, how to design analytical testing strategies for E&L, case studies on identification and risk assessment E&L in single-use system, container closure system and delivery devices, and impact of leachables on biologics safety.

We invite you to present a poster and join colleagues from around the world in this discussion of the key challenges and solutions for E&L testing in biologics.

MATERIAL CHARACTERIZATION AND ANALYTICAL STRATEGY

2:00 Chairperson’s Remarks

Diane Paskiet, MS, Director of Scientific Affairs, West Pharmaceutical

2:05 Experimental Design Considerations for Extractables Simulation Studies

Dennis Jenke, Ph.D., Baxter Distinguished Scientist, Technology Resources, Baxter Healthcare Corp.

A simulation study produces an extractables profile that appropriately mirrors a test article’s leachables profile. This is accomplished via a controlled extraction study which uses an extraction solvent to mimic the “leaching power” of the contact solution (such as drug product) and accelerates the clinical conditions of contact (shorter duration at higher temperature). This presentation addresses those factors to consider in terms of simulating solvent selection and proper acceleration.

2:35 Qualitative Characterization and Visualization of Complex Mixtures of Extractables/Leachables and Other Pharmaceutically Relevant Compounds Using High Resolution LC-MS with 2-D and 3-D Mass Mapping

Douglas E. Kiehl, Principal Research Scientist, Spectroscopy & Raw Materials, Bioproduct Research & Development, Eli Lilly & Company

Extractables and leachables (E&L) associated with packaging and container systems, delivery devices and process equipment can pose risk to the safety and quality of drug products. E&L samples may represent complex mixtures of diverse organic molecules, presenting significant analytical challenges. This presentation discusses the application of 2-D/3-D mass mapping, mass difference correlation and visualization of high resolution exact mass LC-MS datasets to simplify interpretation of such complex mixtures.

3:05 Sponsored Presentation (Opportunity Available)

3:35 Refreshment Break in the Exhibit Hall with Poster Viewing

4:15 Extractables and Leachables Strategy for Parenteral Drug Products

Meera Agarkhed, Manager, Formulation Development, Eli Lilly and Company

This presentation will discuss extractables and leachables risk assessment strategy for manufacturing and fill finish operations and their impact on biotherapeutics safety, efficacy and stability.

4:45 The Value of the “Simulated Study” as a Tool to Predict Actual Leachables in Parenteral Drug Products

Carsten Worsøe, Principal Scientist, CMC Analytical Support, Novo Nordisk

This presentation will describe the simulated study as the optimal study to predict actual leachables in different parenteral drug products including cartridges, vials and prefilled syringes and how it can be used to reduce the risk for having critical leachables and reactions between leachables and formulation components or the active ingredient at a late drug development phase. The presentation will also describe a number of different opportunities on how to perform simulated studies and finally a number of cases will be presented showing the value.

5:15 A Vision of Understanding Extractables and Leachables; Impact on Drug and Device Manufacturing Processes

Yasser Nashed-Samuel, Ph.D., Principal Scientist, Process and Product Development, Amgen, Inc.

Extractables and leachables are critical product contact assessments throughout the product life cycle due to their possible impact on product quality and patient safety. A thorough evaluation of the extractables from product contact surfaces during product development will ensure successful long term leachables testing, process robustness, product quality, device functionality and patient safety. Selected case studies presented will reflect the importance of extractables evaluation to product development.

PROCESS AND PACKAGING FACTORS AFFECTING AGGREGATION, SAFETY AND EFFICACY OF BIOLOGICS

8:30 Chairperson’s Remarks

Joël Richard, Ph.D., Vice President, Peptides, CMC & Engineering, Ipsen

8:35 Predicting the Risk of Extractables and Leachables (E&L) Interacting with Therapeutic Proteins

Kim Li, Ph.D., DABT, MPH, Senior Manager, Environment, Health, Safety and Sustainability, Amgen, Inc.

Therapeutic proteins can be subject to chemical modifications which may lead to product quality and safety concerns. Extractables and leachables (E&L) arising from process- and product-contact surfaces present the risk of interacting with the protein products. This presentation will describe the mechanisms of such interactions and the use of an in silico software that classifies E&L structures into reactive functional groups for risk prediction.

9:05 Extractables & Leachables in Liquid Formulations of Proteins: Impact on Stability, Aggregation, Potency and Immunogenicity of Drug Product

Joël Richard, Ph.D., Vice President, Peptides, CMC & Engineering, Ipsen

Extractables and leachables are impurities that can contaminate liquid formulations of biologics, leaching from the surface of glass walls or being extracted from the rubber stoppers and plungers. They can interact with and degrade proteins, modifying their higher order structure, forming mixed micelles, or composite protein aggregates. These impurities may have a strong impact on stability, quality attributes and immunogenicity profile of the protein drug products.

9:35 Defining the Attributes of Aggregated and Monomeric Biotherapeutics that Enhance Relative Risk of Immunogenicity

Marisa K. Joubert, Ph.D., Senior Scientist, Process & Product Development, Amgen, Inc.

10:05 Coffee Break with a Poster Pavilion

11:00 Investigation of Reversible Self-Association during Early Stage Development of a Low Concentration Antibody-Drug Conjugate

Elizabeth Bartlett, Scientist II, Analytical & Pharmaceutical Sciences, ImmunoGen, Inc.

Reversible self-association is often present in high concentration antibody products, but may also occur in lower concentration preparations. In the case of antibody-drug conjugates (ADCs), a novel class of molecules for the treatment of cancers, this property can present substantial challenges to successful formulations. In this study, a multi-technique approach was used to identify and investigate the effects of various excipients on reversible self-association in a low concentration ADC.

11:30 Characterizing Changes in Protein Quality Attributes to Assess Leachable Risks from Single-Use Bioprocess Containers

Nina Xiao, Senior Research Associate, Late Stage Pharmaceutical Development, Genentech, Inc.

Application of single-use bioprocess containers for the manufacturing of biologics have increased significantly over the years. This study examines two monoclonal antibodies in a small-scale stressed model to detect and assess the presence of leachables by monitoring protein quality attributes. The results from this study demonstrate that the stress model can inform a risk assessment of leachables on protein quality attributes during routine manufacturing. Leachable characterization will also be discussed.
