Abstract

Graphical abstract: The recent review proposes three cornerstones of bioprocess development to play a key role in responding to current trends in the pharmaceutical industry with the potential to decrease the development timelines and costs. Highlights: Enhanced competition, tight development timelines and increased drug personalization are the current challenges of biotherapeutics production. A focus on well-established biological and technology platforms enable fast and efficient development. Process design supported by in silico tools and small scale systems help to anticipate process robustness and enable a fast process characterization. Advanced model-based monitoring and control strategies enable rigorous control and the reduction of batch failures. Abstract: Current trends in the biopharmaceutical market such as the diversification of therapies as well as the increasing time-to-market pressure will trigger the rethinking of bioprocess development and production approaches. Thereby, the importance of development time and manufacturing costs will increase, especially for microbial production. In the present review, we investigate three technological approaches which, to our opinion, will play a key role in the future of biopharmaceutical production. The first cornerstone of process development is the generation and effective utilization of platform knowledge. Building processes on well understood microbial and technological platforms allows to accelerate early-stage bioprocess development and to better condense this knowledge into multi-purpose technologies and applicable mathematical models. Second, the application of verified scale down systems and in silico models for process design and characterization will reduce the required number of large scale batches before dossier submission. Third, the broader availability of mathematical process models and the improvement of process analytical technologies will increase the applicability and acceptance of advanced control and process automation in the manufacturing scale. This will reduce process failure rates and subsequently cost of goods. Along these three aspects we give an overview of recently developed key tools and their potential integration into bioprocess development strategies.
