KEYNOTE PRESENTATIONS:

2:00 Correlating Protein-Protein Interactions and Aggregation Rates over Broad Concentration Range: Misconceptions, Challenges and Promising Approaches

Atul Saluja, Ph.D., Senior Research Investigator II, Drug Product Science & Technology, Bristol-Myers Squibb

Protein–protein interactions (PPI) and rates of aggregation (kagg) were quantified systematically for a monoclonal antibody (MAb) across a broad range of concentration in presence and absence of excipients. Hypotheses based on thermodynamic activity and fluctuation theory were inconsistent with experimental kagg and scattering data. However, arguments based on surface contact probabilities were reasonably successful in providing a semi-quantitative correlation. Challenges and opportunities for such an approach are further discussed.

2:45 Applications of AU-FDS to High- Concentration Antibody Interactions

Thomas Laue, Ph.D., Professor, Biochemistry and Molecular Biology; Director, Biomolecular Interaction Technologies Center (BITC), University of New Hampshire

Will discuss two applications of AU-FDS. First, high-concentration antibody solutions may exhibit excessive viscosity due to weak interactions between proteins. A case will be built that they are a consequence of a balance between attractive electrostatic energies and repulsive desolvation energies. Second, how does a highconcentration protein background influence an IgG-antigen interaction? Here, both the IgG and the antigen are multi-valent, which leads to very large networks being formed in dilute solution. Are these large structures observed in serum?

PROCESS CHALLENGES

8:25 Chairperson’s Remarks

Mark Yang, Ph.D., Director, Fill Finish Development, Sanofi Genzyme

8:30 Detection and Management of Protein Aggregates during Downstream Processing

Danny Chou, Ph.D., President and Founder, Compassion BioSolution; Former Senior Research Scientist, Biologics Development, Gilead Sciences

It is known that protein aggregation is a significant bottleneck in the development of efficient and cost-effective biologics purification process. The goal of this presentation is to use a case study to illustrate how one may detect the “seeds” of protein aggregate that occur early in the process in order to reduce the formation of larger particulate in the final drug product and reduce processing cost.

9:00 Case Study: Formulation pH Shift Caused by Protein Concentration Increase

Mark Yang, Ph.D., Director, Fill Finish Development, Sanofi Genzyme

In this new case study, it has been observed that the formulation pH decreases as its protein concentration increases. This pH shift becomes more pronounced in the high concentration formulations or in the diafiltration step where protein gets concentrated. The underlining mechanisms responsible for this pH shift, along with mitigation strategies, will be discussed.

9:30 Impact of Charge Isoforms on Stability of Antibody Formulations Manufactured Using High Titer Bioprocess

Shantanu Sule, Ph.D., Senior Engineer, Parenteral Formulations & Process Development, Biogen

This presentation will cover how molecular charge isoforms from upstream drug substance process influence protein stability in the downstream drug product. Particular post-translational modifications and chemical degradation will be discussed that lead to charge isoform impacting protein aggregation. Further, isoform fractionation approaches and novel stability study designs will be presented that help elucidate the impact of isoform species in high titer and high concentration biopharmaceuticals.

10:00 Networking Coffee Break


FORMULATION & ANALYTICAL STRATEGIES FOR HIGH-CONCENTRATION PROTEIN FORMULATIONS

10:30 Co-Formulation Development of Monoclonal Antibodies and Recombinant Human Hyaluronidase (rHuPH20) – A Case Study

Claudia Mueller, Ph.D., Senior Scientist, Group Leader, Late-Stage Pharmaceutical and Process Development, F. Hoffmann-La Roche Ltd.

Subcutaneous application faces limitations with regards to the drug volume that can be administered. To enable delivery of the necessary doses, increase in the concentration of the drug and/or temporary enlargement of the interstitial space at the injection site, e.g. by using rHuPH20, are potential strategies to face this challenge. This presentation highlights the drug product development of co-formulations consisting of highly concentrated monoclonal antibodies and rHuPH20. The talk will focus on formulation and process development challenges arising from combination of two very different proteins in order to maintain both stable and active within one formulation.

11:00 Formulation Strategies for High-Concentration, Low-Volume Injectables

Charles Wescott, Ph.D., Vice President, Research and Development, Protein Formulation, Arsia Therapeutics

At concentrations exceeding 100 mg/mL, many biologics are highly viscous, and can suffer reduced colloidal stability. Formulation designs targeting the protein-protein interactions mediating these problems can produce highly-concentrated drug products with good stability, syringeability, and injectability characteristics. These advanced high-concentration formulations allow biologics that would otherwise be dosed by i.v. infusion to be administered by s.c. injection, or delivered by low-volume devices.

11:30 Building a Better Bridge: Biophysical Tools to Better Understand the Complexities of High Concentration Biotherapeutics

Mike Marlow, Ph.D., Senior Staff Scientist, Protein Biochemistry, Regeneron Pharmaceuticals, Inc.

The thermodynamic interactions that govern a variety of protein therapeutic and solution properties are distinctly protein concentration dependent. Manufacturing and dosing of therapeutic monoclonal antibodies frequently calls for high protein concentration solutions and the resulting non-ideality complicates reliable estimation of critical properties from measurements under dilute conditions. We illustrate the utility of different biophysical tools in bridging the dilute - high concentration gap by characterizing two antibodies that exhibit contrasting concentration-dependent behavior.

DELIVERY & DEVICES FOR HIGH-CONCENTRATION / HIGH-VOLUME FORMULATIONS

1:25 Chairperson’s Remarks

Jan Jezek, Ph.D., CSO, Research & Development, Arecor Ltd.

1:30 Strategies for Overcoming Long Reconstitution Times of Lyophilized Highly Concentrated Protein Formulations

Robin Bogner, Ph.D., Associate Professor, Pharmaceutical Sciences, University of Connecticut

High protein concentration is often accompanied by unacceptably long reconstitution times of 40-60 minutes. Formulation and lyophilization cycles have been found to influence the time to achieve complete reconstitution. In addition, there are an increasing battery of methods to assess the potential for long reconstitution times. Several strategies, some of which may be counterintuitive, can be used to reduce the reconstitution times of challenging formulations.

2:00 Product Differentiation through Formulation and Device

Jan Jezek, Ph.D., CSO, Research & Development, Arecor, Ltd.

In the increasingly competitive biopharmaceutical market, convenience of use has become an essential feature for a product to succeed. Convenience can be achieved by smart devices as well as formulations that enable high protein concentration or use of the product outside the cold chain. This talk will focus on unique formulation strategies for stable concentrated products as well as related device choices that enable development of competitive biopharmaceuticals.

2:30 Talk Title to be Announced

Reza Esfandiary, Ph.D., Scientist II, Department of Formulation Sciences, MedImmune

3:00 CMC Strategies on Scaling Up and Down for High-Concentration Protein Formulations

Jamie Tsung, Ph.D., Principal Scientist, Momenta Pharmaceuticals, Inc.

Highly concentrated therapeutic proteins are prone to be viscous and aggregate posing developmental and CMC challenges in purification, formulation, analytical development, manufacturing, product stability, syringeability and injectability. This talk provides a review of current strategies and technologies used in product development to overcome these CMC challenges and minimize the impact on product quality.
