Edward_ZartlerEdward R. Zartler, Ph.D., Senior Group Leader, Biophysics, Analytical R&D, Pfizer

The robust structural characterization of biosimilars, complex therapeutic proteins, is crucial to demonstrating biosimilarity. NMR and X-ray are the two most powerful methods to address the structure of biosimilars.

11:45 Analytical Comparability and Characterization of a Non-Covalent Heterodimer Biotherapeutic

Justin Prien, Ph.D., Associate Director, Analytical Development, Shire

This presentation discusses the analytical comparability for a non-covalent heterodimer biotherapeutic performed to facilitate product developmental continuity. The analytical comparability strategy was designed to assess the similarity of the potential critical quality attributes and mitigate false negative results. At the development stage comparability can be challenging due to analytical method immaturity, the extent of process and product knowledge, and a limited number of manufacturing batches from the different processes.

2:35 Role and Relationship between Biophysical and Analytical Data in Formulation Development and Comparability Assessments

Haripada Maity, Ph.D., Research Advisor, Formulation Development, CMC Development, Eli Lilly and Company

Biophysical and analytical measurements are often performed for formulation development and during comparability assessment of protein therapeutics. The roles and relationship of these data and how they relate to method sensitivity, analysis, and interpretation is an im-portant avenue of discussion. This presentation will discuss the utility of these multidimen-sional approaches and the connectivity of these data in terms of thermodynam-ic/conformational stability and kinetic stability of protein.

4:00 Comprehensive Characterization of Product Variants and Higher-Order Structure of Monoclonal Antibodies with Case Studies

Renata Varga, Ph.D., Characterization Scientist, Analytical Sciences, Global

Biological CMC, Teva Pharmaceuticals

Characterization of monoclonal antibodies under development is a key step to better understand the properties and behavior of that new mAb, especially for product variants. After a critical quality attribute assessment, the anticipated variants can be thoroughly characterized based on a well-designed plan. Characterization data on mAb size variants, aglycosylated species, and isoforms (charge, disulfide) by several analytical methodologies will be presented.

4:30 Therapeutic Protein Characterization for Process Development – a Case Study

Quanzhou Luo, Ph.D., Senior Scientist, Process Development, Amgen

Although therapeutic proteins are relatively stable, they can undergo a variety of degradations during manufacturing, formulation and storage. It is, therefore, very important to characterize the biophysical and biochemical properties of the degradations to better assess their safety and efficacy. With the implementation of the quality by design (QbD) concept to drug devel-opment, monitoring product quality attributes (PQAs) during process development has be-come increasingly critical.

8:35 Assessing the Higher-Order Structure of Therapeutic Monoclonal Antibodies by NMR Spectroscopy

Yves_AubinYves Aubin, Ph.D., Research Scientist, Regulatory Research Division, Health Canada

Monoclonal antibodies (mAbs) are the fastest growing class of therapeutic protein. In addition, a number of mAb products have lost or will lose patent protection. Here we will present our latest efforts in applying NMR spectroscopy to obtain high-resolution structural information to facilitate the assessment of this critical quality attribute. The approach is applicable in the context of a comparability exercise, whether it is for innovator or biosimilar products alike.

9:05 Use of Steady-State and Time-Resolved Fluorescence Spectroscopy for Higher-Order Structure Characterization

Michael_IgnatovMichael Ignatov, Ph.D., Senior Scientist, Biologics Development Analytical Sciences, Allergan, Plc

Intrinsic tryptophan fluorescence serves as a highly sensitive indicator of the higher-order structure of proteins. Tryptophan fluorescence properties are extremely sensitive to the local environment around tryptophan and solvent accessibility. Differences in the fluorescence properties of proteins are measured to monitor the changes in the higher-order structure. Effect of chemical modifications, chemical unfolding, thermal unfolding, etc. on the spectral properties and fluorescence lifetimes is assessed using several model proteins.
