Quality by Design for Effective Bioprocess Characterisation and Validation

Get expert guidance on choosing on how best to integrate QbD, DoE and PAT into lifecycle approach to process characterisation

A series of stimulating interactive lectures from experts in the field and teamwork activities will enable you to:

    • Learn about the latest FDA and EMEA regulations with regards to QbD, PAT, process characterisation and validation.
    • Understand current and future perspectives of the impact of QbD and PAT on the effort required for process characterisation.
    • Learn how to perform Risk Assessments to determine Critical Quality Attributes (CQAs) and Critical Process Parameters (CPPs).
    • See examples of how to combine scale-down models with historical knowledge and DoE to map out Design Space.
    • Understand the principles behind the characterisation and validation of unit operations, such as fermentation, filtration, chromatography, formulation through to supply chain logistics.
    • Learn how to apply QbD to continuous operations, e.g. perfusion culture and filtration operations.
    • Explore the impact of single-use components on validation needs
    • Apply QbD when implementing pre/post-approval process changes.
    • Network with sector leaders and subject matter experts.

    This module is suitable for scientists and engineers working in the biotech sector that are involved or liaise with people in Process Development, Process Characterisation, Validation, Manufacturing, Quality and Regulatory activities.

    Module Leader

    Professor Ajoy Velayudhan is Professor of Bioprocess Engineering and Biotechnology in the Department of Biochemical Engineering at UCL. He is also one of the first cadre of recipients of the EPSRC Manufacturing Fellowships. He has spent ten years in the biotechnology industry in the USA, including periods at Johnson & Johnson, and Bristol-Myers Squibb, where he led process development (R&D) groups in cell culture, downstream processing, and formulations and freeze-drying. His research interests include experimental, computational and theoretical approaches to developing integrated and robust mathematical models for the entire bioprocesses (from cell culture through downstream processing to fill and finish) required to make modern and future biologics medicines. Other research areas include the principled development of models for cellular therapies and other systems in regenerative medicine, and the use of molecular dynamics to isolate important mechanisms in a variety of areas, including the development of tailored excipients as protein formulations.
