2:05 Hydrogen Deuterium Exchange in Lyophilized Solids: Correlation with Protein Stability
Elizabeth M. Topp, Ph.D., Dane O. Kildsig Chair and Department Head, Department of
Industrial and Physical Pharmacy, Purdue University
Solid-state hydrogen deuterium exchange with mass spectrometric analysis (ssHDX-MS) provides high resolution structural information for proteins in lyophilized solids. Recent studies with a lyophilized monoclonal antibody (mAb) show that deuterium
incorporation is highly correlated with chemical and physical stability on storage, and will be presented here.
2:45 Prediction of Protein Stability in Lyophilized Formulations: Miscibility, Mobility, and Microenvironmental pH
Eric J. Munson, Ph.D., Patrick DeLuca Endowed Professor, Department of Pharmaceutical Sciences,
College of Pharmacy, University of Kentucky
The stabilization of proteins in lyophilized matrices requires that the protein and cryoprotectant, such as sucrose or trehalose, be in intimate contact with each other and have reduced mobility in the matrix, and that the buffer maintains the optimized
solid-state ionization (i.e., pH equivalent). We have been using solid-state NMR spectroscopy to show that the stability of the protein, especially against aggregation, requires that the protein and cryoprotectant remain intimately mixed and relatively
3:15 Roles for Antifreeze Polypeptides in Optimizing Lyophilization Formulations and Protecting Stability of Proteins
Xin Wen, PhD, Professor, Department of Chemistry and Biochemistry, California State University, Los Angeles
In this talk, we will discuss the potential use of antifreeze polypeptides (AFPs) in optimizing lyophilized formulations and protecting stability proteins. Naturally produced by many cold-adapted organisms including fish, insects, and plants, AFPs
are known for their ability to inhibit ice growth and recrystallization efficiently. We have demonstrated that AFPs can also control the crystallization of carbohydrates and nucleosides and protect proteins under extreme temperatures.

4:30 Predicting Stability of Freeze Dried Proteins Using Materials Dynamics
Marcus T. Cicerone, Ph.D., Biomaterials Group, National Institute of Standards
I will describe efforts in our lab towards understanding the fundamental connection between picosecond timescale, molecular length scale motions and protein degradation processes in lyophilized formulations. I will also discuss our efforts in developing
benchtop methods to rapidly predict protein stability using this fundamental understanding.
5:00 New Tools for Prediction of Stability of Freeze Dried Products - A Cold Perspective
Miguel Ângelo Rodrigues, Ph.D., Researcher and Invited
Professor, Chemical Engineering, Instituto Superior Técnico, University of Lisbon
Reactions that can compromise stability and quality of the freeze dried products happen within the ice structure. However, it’s difficult to correlate parameters with results, because of the complexity and intricate relation between thermodynamic
and kinetic variables leading to cryoconcentration, cold-denaturation, precipitation or aggregation. Experimental and modeling approaches were developed to understand and anticipate some of these mechanisms, which can assist the development of
more rational formulations and optimized freeze drying procedures.

8:35 Optimizing the Vial Heat Transfer Coefficient for Pharmaceutical Freeze Drying: A Case Study Illustrating a New Press-Blow Technique for the Manufacturing of Molded Vials
Tim Wenzel, Scientist, Ph.D. Candidate, University of Erlangen GILYOS
GmbH on behalf of Henning Gieseler, Ph.D., CSO, Pharmaceutical Development, GILYOS GmbH
The vial heat transfer coefficient (Kv) serves as a key parameter to assess the total heat flow to a vial during primary drying. The present case study discusses the heat transfer characteristics of a vial manufactured by a blow-blow and new
press-blow process, and subsequently discusses the impact of such a design and manufacturing features on Kv. The results clearly suggest a significant impact of the manufacturing technique on Kv.
9:05 Freeze Drying of a Low Tg’ and High Fill Protein Drug Product: The Critical Role of Freezing on Primary Drying Process Performance and Final Product Quality Attributes
Xiaofeng Lu, Ph.D., Principal Research Scientist, Pharmaceutical Development, AbbVie, Inc.
Development of an efficient and robust freeze drying cycle was challenging for low Tg’ and high fill protein drug product. A regular freezing protocol resulted in a long primary drying process and undesired product appearance. In this
presentation, the critical role of freezing conditions on primary drying process performance and product quality attributes will be demonstrated. An effective freezing protocol will be recommended to achieve an efficient primary drying
process and desired product quality attributes.
9:35 Emerging Drying Techniques for Manufacturing of Pharmaceutical Biologics
Qi (Tony) Zhou, Ph.D., Assistant Professor, Industrial and Physical Pharmacy, Purdue University
Traditional lyophilization is a batch and time-consuming process with low energy consumption efficiency. There are increasing interests to develop emerging drying techniques that have higher processing efficiency and lower costs while maintain
product quality. A few drying techniques have been attempted such as spray drying and spray freeze drying. This talk will discuss the advantages and disadvantages of these emerging drying techniques for the application of biologics.

12:20 Lyophilisation of High Concentration Protein Formulations: Excipient Selection and Challenges
Valeria Gervasi, PhD Candidate, School of Pharmacy, Synthesis
& Solid State Pharmaceutical Centre,University College Cork
The design of lyophilisation process for high concentration protein formulations can be challenging due to the necessity of employing products with high total solute concentration, resulting in high cake resistance. Excipient selection
and modelling approaches, as well as the identification of critical parameters for the optimization of the lyophilisation process, can aid the efficient manufacture of a stable product with prolonged shelf-life.

2:05 Secondary Ice Nucleation as the True Driver for Product Heterogeneity When Controlling Ice Nucleation in Pharmaceutical Freeze Drying
Tim Wenzel, Scientist, Ph.D. Candidate, University of Erlangen GILYOS GmbH
The common ground for controlled ice nucleation technologies in freeze drying is that they can only control primary nucleation. However, formation of the ice network throughout the product solution determines the overall drying performance
and product quality. To obtain optimum homogeneity, secondary nucleation and ice crystal growth must be controlled post primary nucleation. Impact factors and appropriate process set-up for two pressure-dependent nucleation technologies
will be discussed.
2:35 Methods to Reduce the Reconstitution Time of High Concentration Lyophilized Protein Therapeutics
Jacob Luoma, Engineer II, Pharmaceutical Processing and Technology Development,
There is increasing interest in producing high concentration lyophilized protein therapeutics. Since reconstitution time increases as protein concentration increases, the product may become inconvenient to use in the clinic if
reconstitution time is not addressed. This talk will review methods that Genentech has evaluated for reducing reconstitution time.
