Solid liquid separation or clarification is the first step in the purification of biological molecules. The clarification is often performed by disc stack centrifugation followed by depth filtration, or depth filtration alone. This case study describes what happened when changing to depth filtration only, and how traditional means of evaluating filtrate clarity does not always describe what you get. Hanne Bak, Ph.D., Staff Engineer, Purification Development, Regeneron Pharmaceuticals | |||
| 9:30 | Obtaining a Constant Product by Applying a Physical Model to an Enzymatic Reaction Step In situations where the starting material of a process step inevitably has a certain variance, a fixed process will yield a varying product. In order to produce a constant product, the process can be varied according to the starting material using a physical / mathematical model combined with at-line analysis, which describes the reaction. This provides a powerful tool for predicting performance and understanding the process. Janus Krarup, MSc, Principal Scientist, Novo Nordisk A/S, Denmark | |||

| 2:15 | Advanced Chemometric Tools - From Data to Knowledge to Increasing Process Understanding and Control Key to understanding the underlying rationale and design of a manufacturing processes is that the 'design' transferred to manufacturing should be demonstrably 'fit' for its intended use. The availability, quality and validity of process development data from early process definition through to formal process characterization studies and ultimately from commercial production are crucial. This presentation reviews how advanced chemometric methods are successfully exploited to aid process development and increase process understanding and control.

| 9:00 | Models for a Priori Identification of Proteotypic Mass Spectrometry Peptides and Proteins The standard approach to identifying peptides based on high resolution mass spectrometry compares mass and elution time to a database of peptides. These models of peptide identification assume that peptides and proteins are equally likely to be identified. However, significant improvements, in respect to computation and accuracy, can be achieved by searching for only peptides/proteins that are detectable (proteotypic) by high resolution mass spectrometry.

| 9:30 | Characterization of Protein Conjugates Analysis and formulation of protein conjugates is challenging due to the effect of the small molecule that is linked to the protein. Additional modes of degradation (relative to recombinant proteins) attributable to the small molecule and the conjugate as a whole also need to be monitored. This presentation highlights the unique challenges associated with this emerging class of product and the approaches to overcome these challenges.

| 10:30 | Characterization of a Fc Fusion Protein and its Degradants by LC/MS Fc fusion proteins are composed of the Fc fragment from a human IgG1 antibody and two active proteins attached to the terminus of the Fc. The degradation products of a Fc fusion protein have been identified and quantified at intact, limited proteolysis, and peptide mapping levels using various LC/MS techniques.

| 11:00 | Modes of Action of HuMax-EGFr (mAb 2F8, zalutumumab) Zalutumumab (HuMax-EGFr), a human IgG1 antibody targeting the Epidermal Growth Factor receptor (EGFr), was found to have two mechanisms of action in cancer therapy. First, it blocks tumor growth by arresting EGFr in an inactive conformation which results in inhibition of signaling. Second, at relatively low dose, potent antitumor effects were observed in mice, which are likely based on the engagement of immune effector mechanisms, in particular ADCC.

| 8:30 | Are We There Yet? An Industrial Perspective of Evolution from Postmortem Data Analysis towards Real-Time Multivariate Monitoring and Control of Biologics Manufacturing Processes Batch biopharmaceutical processes that are typically comprised of a series of unit procedures operated in batch mode to produce therapeutic proteins have complex reaction mechanisms and non-linear, time-variant process dynamics that make their modeling, monitoring and control challenging. Multivariate methods provide very efficient means of analyzing abundant and complex data generated by these processes as well as helping to set up very effective means of monitoring and control. This presentation covers the current state-of-the-art, provides real-world examples and summarizes potential future directions.

Typically, quality specifications are set by statistical descriptors from clinical lots. For example, standard deviations or ranges provide a basis for setting specification limits. This method is only appropriate when a quality space can be described by a convex-like space. The interactions among parameters often violate this assumption. This presentation provides a case study to demonstrate this deficiency and how to overcome it. Mike Su, Ph.D., Manager, BioPharma Technology Group, Bayer Corporate and Business Services LLC | |||

| 11:00 | Applying Structural and Stability Information in the Development of Protein Manufacturing Processes: A Biophysical Approach At Diosynth, we have the privilege of developing comprehensive manufacturing processes for a variety of protein molecules that have distinct structural and stability characteristics. During process development, biophysical assays, such as dynamic light scattering, calorimetry, circular dichroism and fluorescence are routinely used to gain understanding of the effects of process variables on protein stability. This presentation reviews several case studies highlighting the utility of these methods in the development of robust and cost-effective manufacturing strategies. Katherine E.
