The Analysis and Characterization of Protein Therapeutic Drugs

(Including Protein Structure and Function)

Instrumental Tools and Techniques for the Characterization and Analysis of
Biotechnology-derived Polypeptide Therapeutics

In late 1995, the FDA initiated important changes in the regulation of protein therapeutic drugs which led to harmonization in the regulation of protein drugs and small molecule drugs. This change placed considerable emphasis on the analytical technologies used to characterize and analyze protein therapeutics.  At the first “WCBP” Conference in January of 1997 a need was identified for a professional development short course focused on training scientists in just these analytical technologies. The resulting course was first presented in March of 1998 and has since been presented to over 2000 scientists worldwide. While undergoing many changes and revisions over the years, the course, now titled the Analysis and Characterization of Protein Therapeutic Drugs, has remained true to the original mission of training scientists in the current, state-of-the-art, technologies used to meet the challenges inherent in analyzing and characterization of complex biomolecules.

The Analysis and Characterization of Protein Therapeutic Drugs immerses those attending in the practical aspects of characterizing and analyzing therapeutic proteins and presents in an adsorbing manner the fundamental principles and practical uses of three fundamental analytical technologies. Topics extraneous to protein analysis are eliminated, allowing the course to focus on the points of each technology essential in protein characterization. Those attending leave with a clear sense of where each technology is used and how to most effectively implement each technology in developing and using effective, efficient analytical methods for characterizing and analyzing therapeutic proteins.

The Analysis and Characterization of Protein Therapeutics Drugs begins by providing a detailed description of protein structure and function followed by a complete discussion of protein modifications and degradations. It then teaches the essential principles and practices of three important instrumental analytical technologies as they relate to the analysis and characterization of polypeptides:

n Chromatography, especially reversed-phase HPLC

n Capillary Electrophoresis

n Mass Spectrometry

 

Course Schedule

Class begins each day at 8:30 am and ends about 4:00 pm each day, except for the fourth day, when class ends at noon.

Day 1

Morning: Protein Structure and Function. The class begins by outlining the various structural forms of proteins, describing the nature and functions of the natural amino acids, secondary, tertiary and quaternary structure. The role and purpose of tertiary structure in protein bioactivity is explained. Internet resources are mentioned.

Afternoon: Protein modifications and degradations discuss natural post-translational modifications, degradations and engineered modifications to therapeutic proteins. The class will include a description of protein degradations such as deamidation, oxidation, denaturation and aggregation, post-translational modifications such as glycosylation and disulfide bonds and engineered modifications such as pegylation and drug conjugates. Peptide mapping is described as a foundation to discuss the analytical technologies. Emphasis is placed on determining and defining Critical Quality Attributes and how to monitor these.
