Woodcock: FDA wary of Vytorin debate

Expect the FDA to stay out of the Vytorin fray, at least for now. So Janet Woodcock (photo), CDER chief, told FDAWeb in an interview (recounted, in turn, by Pharmalot). The agency is afraid of seeming "defensive" if it weighs in now. But Woodcock did make clear that FDA still considers lowering "bad" cholesterol--which Vytorin did quite well in the Enhance study--to be a valid surrogate for heart-disease prevention.

Scientific nitpicking about LDL is misleading people, Woodcock said: "[T]here is some little point that the scientists are arguing about, and then the media get on it, and they start throwing the baby out with the bathwater," she said. "...[but if] people think we're just being defensive, we wouldn't make a difference in this environment."

Meanwhile, new data is in on the expected drop-off in Vytorin and Zetia scrips. A Deutsche Bank analyst surveyed primary care docs and found that 75 percent expect usage of both drugs will drop in their practices. The analyst now predicts that market share for Vytorin will drop to 9 percent from 16 percent. Zetia, one of the drugs in the Vytorin combo, will see its share drop to 6 percent from 9.5 percent, the analyst concluded.

Some of that drop-off will be in new scrips, some from patients switching. In an investor note, the analyst predicted "increased utilization of other statins, especially [Pfizer's] Crestor."
