By way of implementing PAT-enabled optimization strategies, manufacturers can go ahead and streamline regulatory submissions, speed-up the product approvals, and also ensure compliance with the strict regulatory requirements.

In its entirety, PAT-enabled optimization goes ahead and serves as a powerful opportunity within the continuous bioprocessing market, thereby encouraging manufacturers to achieve higher levels pertaining to process efficiency, quality, and regulatory compliance.

High productivity and affordability drive adoption in terms of chromatography systems in continuous bioprocessing

It is well to be noted that the consistent bioprocessing market happens to be further segmented by product into chromatography systems with filtration systems along with devices; consumables; bioreactors; cell lines, cell culture media, buffers, and reagents; and also other products. The chromatography systems as well as consumables have in them resins, membranes, buffers, solvents, columns, reagents, and other consumables like autosamplers, along with fittings and tubing detectors, among others. Consistent chromatography techniques are indeed critical in continuous downstream bioprocessing so as to achieve high purity for the proteins, and these processes happen to be at an advanced level and have several opportunities. Continuous operation can be maintained by way of running multiple chromatography columns in countercurrent or even in a concurrent manner. This is due to the fact that the loading is done in the first column, and all the other following stages, such as elution, regeneration, washing, and re-equilibration, happen to be completed within the succeeding columns. The continuous mode of the operation goes on to include countercurrent chromatography- CCC, countercurrent tangential chromatography- CCT, , multicolumn countercurrent solvent gradient purification chromatography- MCSGP, simulated moving bed- SMB chromatography, and continuous annular chromatography- CAC.

Due to an increased demand pertaining to biologics, the requirement for intensification of the upstream bioprocess so as to boost productivity as well as lower manufacturing costs has risen. There happen to be several studies that have been published by the National Center for Biotechnology Information- NCBI thereby showing the successful application of integrated continuous bioprocessing in the production of monoclonal antibodies- mAbs. For example, a study achieved an almost 80% rise in productivity by way of utilizing one-column continuous chromatography- OCC and perfusion bioreactor culture with alternate tangential flow technology- ATF.

Furthermore, manufacturers happen to be increasingly shifting their focus to chromatography systems so as to streamline their production processes and also meet growing market requirements. In June 2023, Waters Corporation and Sartorius AG went on to announce a partnership to come up with integrated analytical solutions for downstream biomanufacturing.

Emphasis on Downstream Processing

Downstream processes happen to have a series of purification steps along with separation steps that are aimed at isolating and purifying the anticipated biopharmaceutical product from the intricate mixture pertaining to cellular components, media, and contaminants that are generated during upstream production. These processes go on to typically include products such as cell filtration systems as well as devices, chromatography systems, and consumables, along with associated accessories and other products. Continuous chromatography systems, in particular, are revolutionizing downstream purification by way of enabling continuous separation as well as the purification of biopharmaceutical products that have exceptional precision and throughput. It is well to be noted that periodic countercurrent chromatography- PCC, continuous CTC, MCSGP, SMB, as well as aqueous two-phase extraction- ATPS has been successfully made use of for the continuous capture from process development to the manufacturing scale all throughout large biopharma companies to thereby avoid the potential process bottlenecks. These techs enhance the process efficiency, product quality, as well as cost of goods. For continuous capture, there happen to be a variety of resins that are available for the Protein A resin screening step, which include MabSelect Sure PCC-Cytiva and Poros ProA-Thermo Fisher Scientific. Such technologies are anticipated to be adopted by more midsize biotech companies as well as CDMOs in the years to come.

Hence, growing focus stressing on reducing production costs in the case of biosimilars and innovator drugs; rising technological advancements like single-pass tangential flow filtration and multicolumn chromatography; the elevating need for intensification of the downstream bioprocess because of an increased titer; and the growing demand for biopharmaceuticals happen to be some of the factors that are responsible for the segment’s high share within the market.
