The Economist Intelligence Unit bears sole responsibility for this report. The Economist Intelligence Unit’s editorial team conducted the interviews, wrote and edited the report. The findings and views expressed in this report do not necessarily reflect the views of the sponsor. John du Pre Gauntt is the author of the report. Our research drew on desk research and in-depth interviews with senior executives and government officials in the field of pharmaceuticals. Our thanks are due to the interviewees for their time and insights. September 2005 © The Economist Intelligence Unit 2005 1 Quality manufacturing A blockbuster opportunity for pharmaceuticals Abstract Pharmaceutical manufacturing is shedding its “poor cousin” image and gaining in importance relative to R&D and marketing. Decades of regulatory and industry standard practice in manufacturing are being reworked to help push operating efficiency in pharma closer to other “normal” industries such as semiconductors, industrial chemicals and even consumer packaged goods. Early reports from the field suggest that progress will require massive change across organisations beyond the factory floor. However, the potential improvements in efficiency and regulatory oversight are too great to ignore. 2© The Economist Intelligence Unit 2005 Quality manufacturing A blockbuster opportunity for pharmaceuticals Introduction changing how it intends to approve pharmaceutical manufacturing applications by emphasising a “quality by design” model of regulatory approval compared with a “quality by test results” orientation that it used until recently. This change is likely to have an extremely significant effect on the entire industry, he pharmaceutical industry is transforming the because every global pharmaceutical player runs mass production of drugs.

Yet compared with because of regulatory uncertainty that they would other industrial sectors such as petrochemicals or stick with old technologies and processes that were semiconductors, there has been a very slow rate of clearly obsolete. The ‘Don’t Tell’ policy covered those introduction into pharmaceuticals of modern process situations where they changed something to improve design principles, measurement and control production but decided not to tell the FDA because technologies, and knowledge management systems. they didn’t want to incur the cost of seeking a Many current production techniques and some supplemental approval.” technologies are decades-old, with some standard The Science Board meetings combined with procedures dating back to the 19th century. “If you benchmarking studies by Massachusetts Institute of look at a lot of our blending technologies, they are Technology and PricewaterhouseCoopers uncovered little better than a giant KitchenAid”, notes a problems on a large scale. The studies revealed that production executive at an international generic-drug the total cost of the current manufacturing manufacturer. “So from a technical standpoint, the infrastructure exceeded that of research and capital equipment technologies have not evolved at development (R&D) by two- or threefold.

FDA, the sheer number of warning letters and the fact Pharma’s low manufacturing productivity is not that nearly every major company was operating under entirely caused by regulations and industry practices. some sort of consent decree prompted the FDA to act. The reality is more complex.
