Evaluation of batch, fed-batch, and perfusion methods for cell culture scale-up

The global market for biosimilars is expected to reach US$25 bn by 2020, when more than ten global blockbuster biopharmaceuticals, with sales of more than US$67 bn, will be off-patent. Many of these drugs are human or humanized monoclonal antibodies (hMAbs).

In this webinar, we present and discuss experimental results from collaboration with TPG Biologics, Inc. The company has developed a suspension Chinese hamster ovary (CHO) cell line that expresses an hMAb which is a potential biosimilar to trastuzumab (Herceptin®), used to treat breast, stomach, and esophageal cancer.

The objective of this research project was to determine if the three primary methods of production for a typical biosimilar (batch, fed-batch, and perfusion) may be simply and easily executed using a single, benchtop bioprocess control system to allow confident process decisions that are scalable to full production. We compared two perfusion processes. In one setup, cells were retained in the bioreactor using the ATF™ System (Refine Technology), a hollow fiber filtration device. In the second setup, cells were cultivated in a packed-bed bioreactor in which cells were immobilized in or between Fibra-Cel® discs. For the fed-batch and perfusion cultivations, we used stirred-tank single-use bioreactors.

This webinar will discuss the outcome of these studies, and will provide an analysis of the benefits of their respective usage in biosimilar production with a particular focus on improving time and cost efficiency.

Join Dr. Stacey Willard, as she shares insights on cell culture process development and production of hMAbs.
