Why drug R&D is so difficult

by Robert Teitelman  |  Published May 25, 2011 at 3:30 PM
beakers125x100.jpgMegan McArdle at The Atlantic tackles pharmaceutical research and asks why developing new drugs are so difficult. Her answer is the obvious one: because it's really difficult. McArdle launches her discussion of this extremely fraught and big-buck question with former National Institutes of Health director Elias Zerhouni who championed "translational research" -- that is getting academics more involved in developing new drugs and less active in pursuing basic research. Zerhouni then went to Sanofi to run R&D and test his ideas and discovered it wasn't quite as simple as all that. No one -- not Big Pharma, not the academically tilting biotechs, not academic researchers -- were all that successful in developing new products. Why he needed to go to a company to discover that is a question McArdle does not ask. McArdle's discussion skips merrily across the sociology of science in the U.S. She makes the assumption, which she eventually abandons, that a "failure" of R&D must be attributable to some structural breakdown in how R&D is pursued. This borrows from traditional rivalries and status fights between chemists and biologists, between corporate investigators and academics, and, with the coming of the genetic revolution, between molecular biologists and their colleagues in biotechs and academia (funded extensively by the federal government and the stock market) and organic chemists at Big Pharma (supported by massive cash flows of blockbuster products). The sociology of all this is fascinating and easy to oversimplify. In the early days of biotech, the clash between "research" and "technology," roughly between molecular biology and chemistry, or biotech and Big Pharma, was at its most intense. The biology crowd believed they were well on their way to fully elucidating cellular processes, making drug discovery, in their eyes, straightforward (the '80s were full of such euphoria -- and Zerhouni's initial optimism may well have tapped some of that). Intellectually, they looked down upon Big Pharma, which was still doing vast amounts of traditional mass screening, a classically bureaucratic kind of science that reflected corporate needs and structures. Big Pharma companies wielded huge financial and organizational advantages and were generally fat and happy, if a little nervous: They had marketing power, clinical testing units, regulatory experts, lobbyists, all fed by those cash flows.
 
The situation immediately grew more complex as Big Pharma evolved toward biotech -- by licensing biotech research, hiring academic biologists, amping up research spending and, in some cases (accelerating recently) acquiring biotechs outright. Meanwhile, the biotechs edged toward Big Pharma by trying to build commercial functions around their research. By the '90s, the use of the word "biotech" had ceased to mean anything more than a small, research-oriented startup -- again, a structural, rather than intellectual, difference. Throughout that period, academia was also changing, reshaped by the commercial eruption represented by biotech, which originated within an academia beset by population pressures and funding needs. The formerly sharp line between corporate and academic research broke down in a variety of ways, and major research universities became aggressive incubators and marketers of their intellectual property. The cliché that academics pursue only pure research into biological processes and that corporate research, meaning biotech and pharma, chase targets or new drugs doesn't begin to capture what's been going on. Lots of academics churned out monoclonal antibodies, for instance; and the genome initiatives, funded both privately and publicly, represented both research and development. Meanwhile, the Big Pharmas and biotechs were conducting lots of original research -- albeit into increasingly complex systems that did not easily surrender their secrets.
 
McArdle spends some time in her post on the role of "middlemen" in drug research. In fact, like so many aspects of finance these days, it's a little hard to discern exactly who these middlemen are. The once-straightforward transmission belt between fundamental research (academia) to basic developmental work (biotech) to product development, testing, regulatory approval and marketing (Big Pharma) has long since broken down -- if it ever really existed in such a pure form. True, there are many biotechs that still act as intermediaries between academia and Big Pharma; but more and more biotechs, following Amgen and Genentech, are beginning to integrate upwards toward Big Pharmas. Part of this might be their nimbleness and smarts (though that's exaggerated), or their sheer numbers, or their ability to attract capital, often from Big Pharmas; more, however, may be attributable to the sheer size of quite-literal drug giants that make incremental growth difficult. That great bulk resulted from decades of prosperity and (more importantly) multiple M&A deals as they tried to buy what they felt they were consistently failing to develop from within.
 
For all of that, McArdle is exactly right: The real problem with pharma development is that we're not quite as smart as we think we are. The advances of modern biology are astounding. But the targets have grown elusive and the complexities of the hunt, which translates into great expense over many years, strains the economics of the business (and that excessive marketing spending makes it even harder to settle for even moderately successful new drugs). The massive complex that is biological research has much to be proud of. But the truth is, whether in academia, biotech or Big Pharma, our intellectual reach still exceeds our grasp. But rather than accept that and move on, we cast about for mechanical reforms -- more money, more projects, more deals, different structures -- that will magically close that gap for us that we resist accepting as a reality.
 
One might add that a similar hubris emerges in that intersection of economics and finance. But that's a post for another day. - Robert Teitelman
