Tracing NIR’s Trajectory for Bioprocess Monitoring


By Paul Thomas, Senior Editor

One of the many good talks at the recent MKS Umetrics user meeting in Chicago was that of Roland Bienert, Senior Scientist for PAT and Sensors & Chemometrics at Sartorius Stedim Biotech. Bienert spoke about various new applications of NIR for bioprocessing, and I followed up with him via email to find out more about the work that he and colleagues in Sartorius’ PAT Unit are doing. This unit, Bienert says, is involved in numerous projects that are part of an internal global PAT program initiated several years ago.

(Can Biopharma Ever Be) Crazy Like a Fox?


By Ali Afnan, Principal, Stepchange Pharma

As many of you know, I’ve spent years advocating the use of real-time process monitoring and control in the pharmaceutical industry. And, as any of you who have read my articles may have noticed, I’ve been disappointed by the fact that process analytical technology (PAT) has, so far, failed to become routine for most drug manufacturers.

QbD Classics: “Quality by Design for Biopharmaceuticals”


What are the must-read articles for would-be practitioners of QbD? I recently posed this question on LinkedIn, and have received several “nominations.” (And we welcome your suggestions.) One seminal article mentioned is “Quality by Design for Biopharmaceuticals,” published last year in Nature Biotechnology and coauthored by FDA’s Helen Winkle and consultant Anurag Rathore, then of Amgen. (Rathore has also coedited, with Rohin Mhatre, a book by the same title, published by Wiley in 2009.)

Success Stories: PAT Addresses Bioprocess Complexity at Amgen


Editor’s Note: As part of our site’s mission to further PAT and QbD within the industry, we will call attention to “success stories” of those companies that are already realizing the benefits of a more science- and risk-based approach. The following is an example, a summary of a talk that Amgen’s Duncan Low delivered last fall, at ISPE 2009. Please send your success stories, long or short, to pthomas@putman.net.
