Medtronic initiates US arm of drug-eluting stent trial

Medtronic has initiated the first investigational site in the US to participate in Protect, the company's global study comparing the Endeavor and Cypher drug-eluting stents on key safety metrics, including stent thrombosis – a rare but serious adverse event in which a blood clot forms inside the stent, with the potential to cause heart attack or death.

Protect sites in the US will serve to provide the FDA with US-specific data on the post-market experience with the Endeavor stent. The US sites will enroll a minimum of 1,000 patients who receive Endeavor stents through Protect or, if necessary, through a nonrandomized continued-access arm.

Laura Mauri, chief scientific officer of the Harvard Clinical Research Institute in Boston, said: “This trial, including at least 1,000 in the US arm, will help further clarify the critical balance between safety and efficacy of drug-eluting stents in real-world practice.”
