Guidant Receives FDA Approval to Expand U.S. Drug Eluting Stent Trial

Approval Sufficient for Completion of Pivotal Trial

Indianapolis, Ind. - Guidant Corporation (NYSE: GDT) today announced that the company has received approval from the U.S. Food and Drug Administration (FDA) to expand enrollment in the U.S. portion of its SPIRIT III drug eluting stent clinical trial to the full cohort of 1,292 patients at up to 80 sites.

SPIRIT III is a large-scale, pivotal clinical trial evaluating XIENCE(tm) V, an everolimus eluting coronary stent system utilizing Guidant''s cobalt chromium MULTI-LINK VISION® Coronary Stent System platform. This prospective, single-blind trial evaluates the safety and efficacy of XIENCE V compared to the TAXUS(tm) Express 2(tm) Paclitaxel Eluting Coronary Stent System for the treatment of coronary artery disease. Results of the SPIRIT III trial will be used to seek FDA approval for XIENCE V for the treatment of coronary artery disease.

The company initially received conditional investigational device exemption approval to begin the trial with a limited number of sites in May. The first patient was enrolled in the study in June.

"SPIRIT III is progressing well, with 117 patients enrolled to date," said John M. Capek, Ph.D., president, Vascular Intervention, Guidant. "New clinical data from this study will serve to broaden our knowledge of the science of drug eluting stents. In the meantime, we look forward to presenting new data in the fourth quarter regarding the one-year follow-up from SPIRIT FIRST."
