Characterization of Biotherapeutics

 

생물학적 제제의 특성 평가

As new product formats progress through development and into the regulatory process, the role of analytical characterization is taking on new meaning. Very new modalities present challenges to both analytical scientists and regulatory agencies alike, and this steep learning curve requires a near-constant cycle of adaptation and innovation. The agencies are requiring sponsors to provide ever more complex data across a wide range of analytical methods, and instrumentation suppliers are striving to support this new era with unique product features, software and feature combinations. The PEGS “Characterization of Biotherapeutics” conference explores the progression of analytical development for an exciting range of emerging modalities and offer a case study forum for those working in the field to share ideas, experiences and solutions that support the preclinical and clinical development of new biotherapeutics.

8:40 Exosome Characterization: Challenges and Advances

Houde_DamianDamian Houde, PhD, Associate Director, Process Analytics, Codiak BioSciences

Exosomes are heterogeneous populations of nano-sized cell-derived vesicles that are released into the extracellular space where they perform critical roles in intercellular communication. As natural nanocarriers, they offer advantages for the establishment of next-generation nanomedicine. However, given their inherent heterogeneity, exosomes are often difficult to characterize. Here, we will present challenges and strategies for the characterization of exosome therapeutics to support the development of robust process development and manufacturing platforms.

9:10 Characterization of Novel and Complex Antibody Formats

Haberger_MarkusMarkus Haberger, PhD, Senior Scientist, Roche, Germany

The number of novel biotherapeutic antibody-based formats in drug development is continuously increasing. Characterization of these formats is challenging. Since established physiochemical and mass spectrometric methods show limited capabilities for characterization of product related impurities, new analytical strategies have to be developed. Here, we present a native MS based analytical approach which successfully assisted in the elucidation of size and charge variants of complex antibody formats such as bispecific antibodies or antibody fusion proteins.

9:40 Expanding Role of Mass Spectrometry in Development of Biotherapeutics

Nanavati_DhavalDhaval Nanavati, PhD, Senior Scientist, AbbVie

The versatility of mass spectrometer has made it the prevailing analytical platform for understanding the distribution, target interaction, off target interaction of biotherapeutics. The role of mass spectrometry in dissecting post translational modified variants of a putative target is also critical in identification of unique targets and development of novel bio therapeutics. In this work, we show specific examples of enhanced foot print of mass spectrometry in early stages of development of biotherapeutics.
