Optimized process performance and productivity with a newly developed protein A membrane

As the biopharmaceutical industry continues to grow and offers new therapies, it also needs to address the following four important pillars: reducing cost, high flexibility, speed to market and increased quality/process robustness. Intensified/connected bio-manufacturing is a hot topic in our industry as it addresses these pain-points by increasing productivity, efficiency, lowering footprint and being cost-effective.

Intensification of the mAb capture step can be achieved by Rapid Cycling Chromatography (RCC). Implementing RCC requires the tuned interaction of a purpose-designed membrane, suitable devices and a supporting skid technology: We developed a new “convecdiff” base membrane that delivers high mass transfer and high permeability, thus resolving the limitations of diffusional and purely convective materials for RCC. To ensure suitability for bioprocessing, providing adequate bed height in a scalable and proven device portfolio is a must. An optimized skid needs to deal with the challenges of running many cycles in a short time - fast flow rates, rapid buffer changes, and handling and analysis of data.

Highly flexible processes using Rapid Cycling Chromatography for mAb capture are enabled by cycle times of 5 to 8 minutes and residence times of seconds. Our prototype membrane exhibits excellent alkaline stability, allowing use of 1 M NaOH for effective bioburden and process risk control. The membrane can be used for more than 100 cycles per batch at low pressure drops, has low fouling propensity, and delivers state-of-the-art performance in terms of contaminant removal and recovery.

Through full lifetime utilization within low batch number processes (e.g. for trial material) and via miniaturization of full-scale manufacturing processes, this new “convecdiff” membrane offers new possibilities for production of clinical and commercial drug substance.
