SPIRIT II: A Clinical Evaluation of the XIENCE V® Everolimus Eluting Coronary Stent System

The SPIRIT II trial was a randomized, single blind, active control, multi-center clinical evaluation. Subject eligibility criteria were similar to SPIRIT III and enrollment duration overlapped between studies. In this study, 300 subjects (3:1 randomization XIENCE V® EECSS: TAXUS™ PECSS were enrolled at 31 sites outside the United States. The primary endpoint was in-stent late loss at 6 months. Secondary endpoints included clinical outcomes at months 1, 6, and 9 months and 1, 2, 3, 4 and 5 years; angiographic results at 6 months and 2 years; and IVUS results at 6 months and 2 years. Follow-up through 3 years is currently available.

Inclusion criteria

• De novo Target lesion(s) must be located in a native epicardial vessel with diameter between 2.25 mm and 4.25 mm by visual estimate
• The target lesion(s) must be in a major artery or branch with a visually estimated stenosis of >= 50% and < 100% with a TIMI flow of >= 1
• Non-study, percutaneous intervention for lesions in a non-target vessel is allowed if done >= 90 days prior to the index procedure or if planned to be done > 9 months after the index procedure

Exclusion criteria

• De novo target lesion(s) located in a major epicardial vessel or a side branch that has been previously treated with any type of percutaneous intervention (e.g., balloon angioplasty, stent, cutting balloon, atherectomy) < 9 months prior to index procedure
• Target lesion(s) restenotic from previous intervention
• Target lesion(s) located in a major epicardial vessel that has been previously treated with brachytherapy
• Target vessel(s) contains visible thrombus
• Patient has a high probability that a procedure other than pre-dilatation, stenting and post-dilatation will be required at the time of index procedure for treatment of the target vessel (e.g. atherectomy, cutting balloon or brachytherapy)
• Patient has additional clinically significant lesion(s) (> 50% diameter stenosis) in a target vessel or side branch for which an intervention within 9 months after the index procedure may be required
