The New York Times today ran a piece on the disappointments encountered by geneticists, recently — in identifying causes of common diseases, through study of the afflicted patients’ genetic code. It truly is a fabulous piece of reporting — do go read it all. I’ll wait.
And so, I was doubly delighted to find that the Times also ran a companion editorial (by Nicholas Wade — do go read it, from top to bottom, as well!), which literally took my breath away, with the grace and precision of its delivery:

. . . .It seems to me the reports represent more of a historic defeat, a Pearl Harbor of schizophrenia research.
The defeat points solely to the daunting nature of the adversary, not to any failing on the part of the researchers, who were using the most advanced tools available. Still, who is helped by dressing up a severely disappointing setback as a “major step forward”?
. . .nature is often a lot more complex than assumed. It now seems that the arm of natural selection is far longer than thought. It has reached way beyond our reproductive years and zapped most harmful genetic variants before they could get to be common in the population. That leaves relatively uncommon variants, lots and lots of them in each case, as the genetic cause of each common disease.
In the last few years gene hunters in one common disease after another have turned up a few causative variant genes, after vast effort, but the variants generally account for a small percentage of the overall burden of illness. With most common diseases, it turns out, the disease is caused not by ten very common variant genes but by 10,000 relatively rare ones.
Today it’s the turn of schizophrenia researchers to make the same discovery. . . .
Schizophrenia too seems to be not a single disease, but the end point of 10,000 different disruptions to the delicate architecture of the human brain. . . .
So the press release writers could have cast it as a noble defeat, were words like defeat a part of their vocabulary, or frankness their masters’ priority. . . .
So — why asenapine (the chemical name of the drug Hassan proposes to brand as “Saphris“, in the United States), that decidedly old-schoolish Schering-Plough candidate awaiting an FDA decision, later this year (rescheduled from the middle of last year) for treatment of schizophrenia? Because we now know several other large pharma players passed on bringing it to market, before Fred Hassan threw perhaps a half-billion dollars into trying to get it approved — at Schering — for schizophrenia.
Yes, the “defeat points in some measure to the daunting nature of the adversary” — and, in the case of asenapine, perhaps even more to the hubris that leads one CEO to think he could succeed where scores of others have assessed (including Pfizer, quite rightly, it seems) that it wouldn’t be “a major advance“.
