Continuous bioprocessing refers to the production of biopharmaceuticals or other bio-products using a continuous flow manufacturing process as compared to the traditional batch manufacturing processes.
In continuous bioprocessing, the production steps like cell culture, purification etc. take place simultaneously in a continuous manner instead of being conducted separately in batches. This allows for improved productivity, higher volume, and reduced costs of production.
Advantages Of Continuous Biomanufacturing
One of the major advantages of continuous biomanufacturing is the significant improvement in volumetric productivity. As the downstream and upstream processes take place simultaneously and continuously, it leads to a dramatic increase in volumetric productivity compared to batch processes. For example, a continuous process can produce drug substance at 10 to 100 times higher rates than a conventional batch process running at maximum timing.
Another important benefit is the reduction in process deviations and increased consistency of the drug product quality. Since continuous processes have a more uniform steady state, they experience less variability between runs. This results in tighter process controls and greater batch to batch consistency in critical quality attributes like glycosylation patterns, aggregate levels etc. ensuring a more robust drug manufacturing process.
Continuous processes also require smaller facility footprints and drastically lower the overall capital investments compared to batch manufacturing. Since multiple steps take place together, the equipment sizes can be optimized. This facilitates the development of compact modular manufacturing facilities. The flexible modular design also allows easy scale-up or changeover to a new product.
Advancing Continuous Biomanufacturing
While the advantages and potential of continuous manufacturing have been realized for some time, there were technological challenges that limited its adoption for biopharmaceutical production. However, in the last decade there has been tremendous progress in overcoming these roadblocks through advances in engineering, control systems and single-use technologies.
One of the key enablers was the development of single-use technologies like pre-sterilized disposable bioreactors, pumps, tubing and sensors. These facilitated the design of versatile portable modular facilities that are well-suited for continuous operation. Earlier constraints of clean-in-place and sterilization in place requirements were overcome.
Advancements in process analytical technologies also played a role. Real-time process control and monitoring tools like in-line spectroscopy, online biosensors were integrated to effectively manage continuous multi-step processes. Sophisticated control systems and supervisory electronic programs were developed to coordinate inputs, outputs across different processing units.
Current Applications And Future Prospects
Currently, continuous manufacturing is being successfully applied at commercial scale for production of some low molecular weight drugs, certain antibody fragments and viral vectors. Companies like Novartis, Merck and Pfizer have FDA approved facilities producing drugs through continuous manufacturing.
However, full scale application to production of complex monoclonal antibody therapeutics is still being pilot tested. Further refinement is ongoing to address challenges in continuous culture and purification of whole mAbs. Once proven, this will truly transform the bioproduction landscape leading to more affordable biologics.
With ongoing R&D, continuous biomanufacturing is poised to rapidly grow in adoption over the next decade. Areas like personalized vaccines and cell therapies are ideal candidates. It could facilitate on-demand production based on patient needs. Combining continuous manufacturing with digital controls opens avenues for real-time process optimization through machine learning and data analytics as well. This will further boost quality consistency and facility performance.
The continuous bioprocessing has significant potential to address the increasing demand for affordable biologics in a more efficient and timely manner. With technology advancements systematically overcoming challenges, its commercialization is gaining momentum. In the future, it could become the preferred technology for large scale production of a wide range of biopharmaceutical products.
