Increase Productivity

Producing Diverse Molecules at Various Volumes

For biopharmaceutical manufacturers to stay competitive while delivering multiple specialized products in smaller batches or blockbuster-level volumes, they must achieve the highest levels of productivity possible. Unfortunately, many are operating within existing stainless-steel facilities built for large volumes, and they cannot compete with facilities that employ single-use solutions and other intensified technologies. 

Concentrated Fed-Batch Fuels Productivity

Intensifying seed train operations is one way to see immediate impact on upstream productivity.

Concentrated fed-batch enables manufacturers to achieve productivity levels up to four times that of standard fed-batch operations. Enabling concentrated fed-batch capabilities is one way Sartorius helps bring process intensification technologies into existing systems or when planning new facilities.  

  • The Biostat STR® single-use bioreactor with integrated XCell ATF® technology and advanced PAT tools for process analytics and control enables perfusion from 50 L to 2000 L.

Manufacturing Complex Products While Controlling Costs

In the past 10 years, the average annual peak sales per molecule has decreased by 50% while average annual costs to develop each molecule increased by 30% – this introduces a mission-critical need to reduce COGS. Manufacturers that currently rely on fed-batch operations have an opportunity to introduce technologies that can quickly modify their existing upstream processes to bring larger gains in productivity and ultimately reduce production costs.

N-1 Supercharges the Seed Train to Bring Costs Down

Implementing N-1 perfusion in the seed train can result in a 30-50% reduction in cost/g compared to standard fed-batch operations and is a key example of process intensification. Sartorius is the only company offering two flexible N-1 seed train intensification options for rocking motion and stirred tank bioreactors along with state-of-the-art integrated analytical tools:

  • The Biostat® RM rocking motion bioreactor with single-use Flexsafe® RM bags, integrated perfusion membrane and in-line analytical & automation tools.

Gaining Flexibility in Your Operations

As medicines become more specialized, the number of low-volume batches and variables in manufacturing processes will increase significantly. Analyses of commercial R&D pipelines between now and 2025 indicate more than 80% of candidates would require production of less than 500 kg per year to meet demand. To keep up with these trends, manufacturing operations need to manage higher throughput of individual therapies as well as accommodate different modalities within the same facility.

Intensified Bioprocessing Made Possible with CFB

​Sartorius can help introduce concentrated fed-batch (CFB) technology, enabling manufacturers to achieve throughput 3-4 times higher than standard fed-batch. This supports intensified bioprocessing and the flexibility biomanufacturers require to remain competitive:

  • The perfusion-enabled Biostat STR® and Biostat® RM bioreactors with integrated PAT automation tools establish a fully flexible intensified seed train.

Reduce Footprint

icon-reduce-footprint

Accommodating a Modular Mindset

Traditional upstream operations that rely on fed-batch processes simply cannot support the diversity of modalities resulting from innovations in protein-based medicines. Meanwhile, specialized medicines mean smaller throughput requirements, with almost 60% of drugs requiring 300 kg/year throughput or less to satisfy patient demands. Given these trends, manufactures are looking for flexible smaller modular Single Use perfusion based facilities to support this diversity in modalities and enable faster changeovers between multiple products.

Perfusion-Based Process for Modular Design

Manufacturing multiple modalities relies on introducing perfusion-based technologies that require smaller bioreactors which often results in modular facility designs. This results in a smaller footprint, lower upfront capex investment and reduced changeover times due to single-use technology implementation.

  • Biostat STR® and Biostat® RM bioreactors, supported with optimal media handling solutions, are suited for different intensified processes and enable small, modular single-use facilities.

Capture Chromatography

Capture chromatography is usually the first purification step and requires optimal reduction of both product- and process-related impurities while maintaining high yields. Chromatography media can be very expensive, and its capacity can be reduced in a single column operation. Packing large columns leads to very labor- and time-intensive procedures that need additional space for processing and storage. It is desirable to have a semi-continuous mode of operation that is rarely satisfied by a single-column system with upstream perfusion processes.

icon-magnifier

Your Need:

For integration with high-titer, intensified upstream processes, you will need semi-continuous capture capabilities and technologies to:

TFF & Final Filtration

Tangential flow filtration (TFF) and sterile filtration are the last downstream steps to obtain the desired product concentration, buffer formulation, and final filtration of the drug substance. Low filter flux and capacity resulting from a very concentrated, potentially viscous feed stream lead to large filtration times and filter areas, thereby increasing overall costs. Furthermore, variation in feed streams and concentration leads to low throughputs over final filtration, resulting in a low yield of the drug substance.

icon-magnifier

Your Need:

To achieve formulated, sterile filtered bulk drug substance, you will need a high-capacity, high-throughput and fully scalable hardware system and consumable solutions for final formulation and filtration that include:

  • Low-adsorptive, high-flux filters
