Reducing Upstream Processing Scale-Up Risks Using QbD
Reducing Upstream Processing Scale-Up Risks Using QbD

Scientists and engineers seeking to develop manufacturing processes for new biopharmaceutical drugs face a number of challenges. Upstream process development must deliver a high-yielding cell culture to meet Cost of Goods (CoGs) objectives. The process must be robust to ensure high batch success rates with a low risk of contaminations and minimal variations in cell growth performance. The biological product must maintain the required product quality attributes, during scale-up from laboratory to commercial scale. Biopharmaceutical companies must address these complex challenges in the shortest possible timeframe and at reasonable effort and cost during development. Doing so allows the early evaluation of products in the clinic and, therefore, effective resource allocation behind projects from the pipeline that are most likely to be successful all the way to the market.

  • Merck Uses Automation And Disposables To Drive Upstream Process Development
    Merck Uses Automation And Disposables To Drive Upstream Process Development

    Automation and disposable technology have offered considerable efficiency improvements to speed cell line development; however, a major challenge with process development for biologics is how labor intensive it can become.  Many different interactions and parameters can impact product quality and product titer, which typically requires iterative rounds of statistical experimentation using up to 20 reactors or more per study. For cell culture mAb processes, this development work can take three to four months to complete, which adds considerable cost for a company in multiple ways. Because of this challenge, Dr. David Pollard, executive director of BioProcess Technology & Expression, BioProcess Development at Merck, and his dedicated technology group wanted to see how the benefits of automation and disposable technologies could be translated into tools to drive high throughput upstream process developmen

ABOUT

Cell Culture
Cell culture is a complex, highly structured process for growing cells, under strictly controlled conditions, outside of their normal environment. Cell cultures stilluse cultures of cells on flat plastic dishes.
This is referred to as two-dimensional (2D) cell culture. Aside from using Petri dishes for growing cells, scientists have for a long time, grown cells within biologically-derived matrices such as collagen or fibrin.
Today, more and more 3d cell cultures are being used because they more closely resemble the in vitro cell growth environment. Most 3d cell cultures in use today are designed for stem cell research, tissue engineering and drug discovery. As the field continues to grow and expand, 3d cell culture availability will likely expand to include other cell culture related fields.
For non-adhesive cells suspension cell cultures are used. In these cultures a cell is placed in the liquid suspension, stirred with a magnetic stirrer to agitate the cell and make it float freely in the suspension. The cell grows, divides and spreads throughout the suspension.
Cell culture refers to the culturing of cells derived from multi-cellular eukaryotes (cells with a nucleus), primarily animal cells. However cell cultures also exist for plants, fungi and microbes that include viruses, bacteria and microorganisms. Cell culture shares closely related methodology with tissue culture and organ culture.
You can separate cells from tissues for use in cultures several ways. Cells can be purified from blood but only white cells will grow in a culture.  Mononuclear cells can be released from soft tissue using enzymes that break the cells away from their substrate or matrix. Pieces of tissue can also be placed in a growth media and the cells that grow from it can be used for cell cultures.
