Process Analytical Technology (PAT) for bioprocessing

On-demand webinar: Innovative Analytical Strategies for Monitoring Critical Process Parameters and Critical Quality Attributes (CQA)

Jonathan Bones, Ph.D.

Biopharmaceuticals are complex molecules produced by living cells, with strict control of bioprocessing being required to ensure the production of high-quality therapeutic proteins.

A key desire by biopharmaceutical manufacturers is PAT for process monitoring and rapid analytical information generation.

Mass spectrometry (MS) coupled to liquid-phase separations offers immense potential for implementation as an online characterization tool, providing a wealth of multi-attribute information at all stages throughout the bioprocess with greater confidence and depth of product attribute knowledge, improving safety and potency.

In this on-demand webinar hear Dr Jonathan Bones of NIBRT and Dr Michael Blank of Thermo Fisher Scientific present an overview of the current state of bioprocessing monitoring, discuss areas for improvement and implementation of PAT, and describe the potential of cGMP-compliant MS characterization throughout bioprocess and lot release.

Is high resolution mass spectrometry the missing piece in continuous bioproduction?

Is high resolution mass spectrometry the missing piece in continuous bioproduction?

In line with quality‐by‐design (QbD) and the desire for continuous manufacture and real‐time lot release, biopharmaceutical manufacturers require advanced PAT for process monitoring and rapid analytical information generation.

High resolution LC‐MS is growing in popularity based on its ability to efficiently offer a wealth of multi‐attribute information which can be used to optimise manufacture and improve drug safety and efficacy.

In this article, co-authored by NIBRT and Thermo Fisher Scientific, the barriers to the adoption of LC‐MS in an online environment are discussed along with recent advances, including the potential application of cGMP‐compliant MS characterization throughout bioprocess and lot release.

Leveraging Platform Analytical Methods for Biopharma QbD

Monoclonal antibody (mAb) CQAs are monitored throughout drug development, manufacture and lot release. While each mAb therapeutic is clearly unique in its targeting and activity, the physicochemical properties of mAbs can often be described within relatively narrow ranges.

A key aspect of biopharmaceutical QbD, which is yet to be truly leveraged, is the use of so-called “platform” strategies for CQA determination. This article will explore the importance of HPLC in mAb CQA determination and monitoring, the benefits of implementing well-developed platform mAb HPLC methods and their potential scope and application.
