Last year, a new drug called Zaltrap was approved as a kind of last-chance therapy for patients with colorectal cancer. Studies suggested Zaltrap worked almost exactly as well as an existing drug called Avastin. In fact, the main difference between the two drugs seemed to be the price.
"I was rather stunned," Dr. Leonard Saltz, who specializes in colorectal cancer, told me.
Zaltrap costs about $11,000 per month — about twice as much as Avastin, Saltz said.
The U.S. Supreme Court hears arguments Monday in a case worth billions of dollars to pharmaceutical companies and American consumers. The issue is whether brand-name drug manufacturers may pay generic drug manufacturers to keep generics off the market. These payments — a form of settlement in patent litigation — began to blossom about a decade ago when the courts, for the first time, appeared to bless them.
