TIME FOR CHANGE
It's not only manufacturing improvements that are driving the shifts toward new expression systems. Many in the industry have
seen trends toward the use of R&D strategies to improve a biopharmaceutical's clinical performance. For example, Patrick Lucy,
global business development leader at Dowpharma's Pfenex business, feels that expression system platforms play a part in clinical
strategy. He believes that the use of new prokaryotic expression platforms will increase because of their short cycle time
in the fermenter and ease of genetic manipulation. Lucy feels that biomanufacturers will shift for many reasons, one of which
is that many companies have failed products on the shelves that, "could and should be made more efficiently, and to higher
clinical standards in newer expression systems."
Indeed, interest in new biopharmaceutical mammalian expression systems appears to be growing rapidly. Andrew Sandford, vice
president at Selexis (Geneva, Switzerland), an expression systems platform company, has noted this change. "Already, we have
more than doubled the number of companies who have begun to actively change the way they plan their early development and
manufacturing strategy," he says. "Many are starting process development four to six months earlier."
An analysis of the trends over the past decade reveals a decline in biopharmaceutical innovation. Oddly enough, in some cases,
this is not because of a lack of new technologies. Rather, it is a failure to adopt these technologies and recognize the potential
for future advancements and opportunity. Companies today are realizing that they cannot continue with the status quo and are
being forced to make bolder choices. In biopharmaceutical manufacturing, the technologies needed to make improvements exist,
and the benefits they can bring have been identified and documented.2 Given that these advantages include improved product yield, enhanced product quality, and lower operating and infrastructure
costs, there can be no arguments about seizing such opportunities. In addition, these technologies can be applied to make
products truly unique (difficult or impossible to copy), which should satisfy even the most stringent assessment of innovation.
