Intensification Strategies Start With a Focus on Process Development

Optimized Scalable Process for Shorter Time to Market

Efficient process development (PD) including a high-titer cell line, clone selection and optimization, and process characterization is critical to develop a scalable upstream process. Now, with technology scalable to fit different intensified process types, PD also enables opportunities to optimize.

Sartorius offers PD solutions for high productivity, flexible upstream intensification processes and increased speed to IND.

Identify the right clone earlier

High throughput screening tools allow for faster selection of optimized clone, media and upstream process.

Accelerate speed to IND submission

Be “right first time” by integrating PAT and data analytic tools for enhanced molecule characterization and process understanding.

Seamless scalability from PD to manufacturing

Bioprocessing 4.0 starts from PD. Data management, trend monitoring and recipe transfer tools ensure reliable scale-up and tech transfer. 

Cell Line & Media Development

For the development of a new therapeutic, early identification of robust, stable and highly productive cell line, media and cell culture conditions suitable for intensified processes are very important. However, the multitude of time- and labor-intensive experiments required to generate a viable cell line result in longer development times and higher cost.

USP PD & Clarification

Accelerating upstream process development and time to IND requires a reliable, scalable and optimized process. However, manual and time-intensive development processes, lack of in-line process sensors and high-capacity clarification solutions extend development timelines.

icon-magnifier

Capture Chromatography

Affinity chromatography captures the target molecule by binding it to a ligand while most of the bulk impurities flow through from the clarified feed stream. However, higher product titers obtained using perfusion processes and the labor-and time-intensive chromatography process development lead to high costs, low productivity and low product yields.

icon-magnifier

Your Need:

Your affinity capture program requires semi-continuous capture capabilities that can be easily integrated with upstream perfusion technology and that supports:

  • Multi-column chromatography
  • Flexibility and automation

Our Unique Solutions:

Sartorius offers  the following flexible and cost-effective solution for affinity chromatography, providing 3-5x productivity along with significant savings on resin costs:

  • BioSMB PD System single-use, automated, high-efficiency multi-column chromatography solution for easy integration with both fed-batch and perfusion processes

Polishing

Polishing chromatography occurs post-capture to remove remaining impurities, such as HCP, DNA and potential viruses, from the product stream. However, the low capacity of chromatography media combined with highly manual and long development processes increase overall costs and extend timelines.

icon-magnifier

Your Need:

For effective polishing, you need scalable chromatography media that enable efficient impurity removal and that feature:

  • High-efficiency and cost-effective media
  • Flexibility, automation and low footprint

Virus Clearance

Viral clearance strategies include virus inactivation and removal. pH adjustment after low pH virus inactivation can lead to a lot of aggregate formation that requires efficient filtration. Robust removal of all potential viruses is also critical. However, low depth filter flux and capacity, low virus filter throughput and early virus breakthrough lead to long filtration times and large filter areas.

icon-magnifier

Your Need:

Your virus clearance strategy requires robust and scalable viral clearance and bioburden reduction solutions that deliver:

  • High-capacity virus filtration
  • Efficient bioburden reduction
  • High product yield
  • Solutions for both in-process holds and buffer solutions

TFF & Final Filtration

Final steps of downstream processing call for tangential flow filtration (TFF) to obtain the desired product concentration and buffer formulation, as well as sterile filtration to ensure sterility and safety. However, multiple experiments for optimized formulation buffer, variation in feed streams and low flux filters result in long filtration times and large filter areas.

icon-magnifier

Your Need:

To produce a final drug substance, you need robust and efficient solutions for formulation screening, crossflow process development and sterile filtration of the drug substance, including:

  • Automatic, high-throughput tools with DOE capability
  • Low-adsorption and high-flux filters  
  • Optimized solutions for different feed streams

Cell Line Development and Clone Selection

PI Process Compatibility Starts Here

Cell Line Development (CLD) includes gene cloning, cell line selection and characterization, media selection and Master Cell and Working Cell banking. Many regard the selection of the appropriate production clone as the most critical step in CLD. If the PD team starts with one clone and then decides to switch to another, it would require major process changes . These changes would bring both significant delays and additional costs.  ​

This is why development and characterization of the cell line for identity, purity and stability are crucial. Sartorius is a reliable partner for these critical steps, offering a Cell Line Development Service, a high-titer cell line with CellcaCHO Expression Platform, and perfusion enabled media.​

Optimization for High Productivity

Cell culture media optimization is a crucial point of focus when exploring perfusion processes to achieve higher productivity. The medium should support rapid growth to high densities, achieve high cell growth rates with maximum viable cell concentration and provide batch-to-batch consistency. 

Process Development Services for Perfusion Process Optimization

Many cell lines were identified in a standard fed-batch process performed in Ambr® 15 microbioreactors. These cell lines show high intensification potential, but the best clone from standard fed-batch selection might not be the best in perfusion.   

Mimicking the perfusion process for clone selection will not only save time, it can also enable a three-fold increase in productivity. Sartorius‘ Process Development Service makes this possible by offering a combined solution that includes cell line, media, process development and the technology to deliver optimal results.
