Participating in the four-year DAPT Study are Natick, Mass.-based Boston Scientific, manufacturer of the Taxus and Promus stents, along with device makers Medtronic Inc. (NYSE:MDT), Abbott Laboratories (NYSE:ABT) and Cordis Corp., the stents arm of healthcare conglomerate Johnson & Johnson (NYSE:JNJ). Drug-makers Bristol-Myers Squibb Co. (NYSE:BMY), Sanofi Pharmaceuticals (NYSE:SNY), Eli Lilly & Co. (NYSE:LLY) and Daiichi-Sankyo Company Ltd. (TYO:4568) also have signed on for the study.
The Harvard Clinical Research Institute, an industry-supported facility based in Boston, enrolled the first of 20,000 individuals slated to participate in the trial in October, 2009. Boston Scientific said its participation will look at the Taxus Liberté stent, which elutes a drug called paclitaxel, and the use of aspirin and Effient, an anti-coagulant made by Eli Lilly and Daiichi Sankyo. The company said it plans to contribute data on the first 1,524 eligible patients from its post-approval study of the Taxus Liberté to the DAPT Study.
