The Current Scientific and Regulatory Landscape in Advancing Integrated Continuous Biopharmaceutical Manufacturing.

There is a trend across the pharmaceutical sector toward process intensification and continuous manufacturing to produce small-molecule drugs or biotechnology products. For biotechnology products, advancing the manufacturing technology behind upstream and downstream processes has the potential to reduce product shortages and variability, allow for production flexibility, simplify scale-up procedures, improve product quality, reduce facility footprints, increase productivity, and reduce production costs. On the upstream side of biotechnology manufacturing, continuous perfusion cell cultures are fairly well established.

A new integrated continuous biomanufacturing platform for continuous production of antibodies at fixed cell volumes and cell concentrations for extended periods with immediate capture is presented. Upstream antibody production has reached technological maturity, however, the bottleneck for continuous biomanufacturing remains the efficient and cost-effective capture of therapeutic antibodies in an initial chromatography step. In this study, the first successful attempt at using one-column continuous chromatography (OCC) for the continuous capture of therapeutic antibodies produced through alternating tangential flow perfusion is presented.
