FDA Proposes Guidelines for Drug-Coated Stents

Article in the Wall Street Journal -- FDA Proposes Stent Guidelines, by Jennifer Levitz.  Here's an excerpt:

The Food and Drug Administration proposed tougher clinical-trial guidelines for drug-coated stents in response to concerns about blood clotting in the artery-opening devices long after implantation.

The move is the first concrete change since the FDA held a two-day meeting in December 2006 about whether such stents increase the risk of clots compared with bare-metal stents years after the procedure. Coated stents don't appear to increase deaths or blood clots overall; whether they increase late clots years after implantation is still debated.

Instead of assessing patients' progress and health in trials nine months after a stent is implanted, the agency will now require companies to submit trial data on patients' health one and two years after the procedure, before stents can be approved. The new draft guidelines appear to codify standards that the FDA used to assess trials for new stents from Medtronic Inc. and Abbott Laboratories.
