Biotech's Hard Bargain

[ed. Looks like a New Yorker kind of day.]

Few people have done better in the recent stock boom than biotech investors. Biotech was the best-performing market sector last year, and in the past two years its stocks rose a hundred and twenty per cent. But suddenly, in late March, the stocks tanked, some falling more than twenty per cent in a few weeks. The selloff can be explained to some extent as a market correction and part of a wider flight from risk. But the real story concerns a revolutionary new hepatitis-C drug developed by the biotech giant Gilead.

Hepatitis C affects 3.2 million Americans; untreated, it leads to scarring of the liver and to liver cancer. Until now, the best treatments cured only about half of patients and often had debilitating side effects. But in December the F.D.A. approved the first in a new wave of hep-C drugs, Gilead’s Sovaldi. This is huge news—not just in medicine but on Wall Street. Vamil Divan, a drug-industry analyst at Credit Suisse, told me, “Sovaldi and the other new hep-C drugs are great drugs for a tough disease.” Sovaldi can cure ninety per cent of patients in three to six months, with only minor side effects. There’s just one catch: a single dose of the drug costs a thousand dollars, which means that a full, twelve-week course of treatment comes to more than eighty grand.

For Gilead this is great. Take an expensive treatment, multiply by a huge number of hepatitis-C patients, and you get a very lucrative business proposition. It’s also good news for patients. But it’s a big problem for insurers and taxpayers, who—given that hepatitis-C patients have an average annual income of just twenty-three thousand dollars—are going to end up footing much of the bill. There has been an uproar of criticism. Private insurers blasted Gilead’s pricing strategy; the pharmacy-benefit manager Express Scripts said that it wanted its clients to stop using Sovaldi once an alternative appears. Then, on March 20th, three Democratic members of Congress sent Gilead a letter asking it to explain why Sovaldi costs so much. The letter had no force of law, but it spooked investors by raising the spectre of what they most fear—price regulation.

Investors love drug companies in part because they often have tremendous pricing power. Drugs designed to fight rare diseases routinely cost two or three hundred thousand dollars; cancer drugs often cost a hundred grand. And, whereas product prices in most industries drop over time, pharmaceuticals actually get more expensive. The price of the anti-leukemia drug Gleevec, for instance, has tripled since 2001. And, across the board, drug prices rise much faster than inflation. The reason for this is that prices for brand-name, patented drugs aren’t really set in a free market. The people taking the drugs aren’t paying most of the cost, which makes them less price-sensitive, and the bargaining power of those who do foot the bill is limited. Insurers have to cover drugs that work well; the economists Darius Lakdawalla and Wesley Yin recently found that even big insurers had “virtually zero” ability to drive a hard bargain when it comes to drugs with no real equivalents. And the biggest buyer in the drug market—the federal government—is prohibited from bargaining for lower prices for Medicare, and from refusing to pay for drugs on the basis of cost. In short, if you invent a drug that doctors think is necessary, you have enormous leeway to charge what you will.
