Webinar: Sub-Visible and Sub-Micrometer Particles in Biopharmaceutical Development

Date: 05 Apr 2017 Location: Online Event City: Online Event Country: Online Event

Characterization of sub-visible particles is a perpetually "hot" topic in biopharmaceutical development and recent increased interest from regulators has heightened its importance. Rapid development of sub-visible particle analytical technology has opened up significant new opportunities for particle characterization including various techniques for sub-micrometer particle measurements. However, it is still unclear if the analytical performance of these techniques can match those of conventional analytical methods. Another factor to consider is the increase in the requirements by Health Authorities and requests for submission of extensive characterization datasets and/ or assessments with regard to expansion of particle control strategies.


This webinar will provide a critical review of available and emerging sub-visible particle characterization technologies, including the advantages and shortcomings of each. The potential applications of individual methods to specific questions which may arise during the development process will be discussed in the context of the larger question of how to build a thorough, phase-appropriate particle characterization and control strategy.
