Post-Approval Clinical Study of the Talent Thoracic Stent Graft to Treat Thoracic Aortic Aneurysms (THRIVE)
- Conditions
- Thoracic Aortic Aneurysms
- Interventions
- Device: Talent Thoracic Stent Graft System
- Registration Number
- NCT00805948
- Lead Sponsor
- Medtronic Cardiovascular
- Brief Summary
The purpose of this study is to evaluate the long-term safety and effectiveness of the Talent Thoracic Stent Graft System for treatment of descending thoracic aneurysms (DTA)following U.S. market approval.
- Detailed Description
A descending thoracic aneurysm is a bulge in the aorta. The aorta is a large blood vessel that carries blood away from your heart to organs in the rest of your body. Your aneurysm is caused by a weakening in the artery wall. If left untreated, this bulge may continue to grow larger and may ultimately rupture (break open) or extend in size to seriously affect other major arteries in the area. In this clinical study the Talent Thoracic Stent Graft will be placed inside your aorta to block the weakened part of the artery wall from the circulatory system.
Medtronic Vascular submitted a Pre-Market Application (PMA P070007) to the FDA on February 28, 2007, and received market approval for the Talent Stent Graft System on June 5, 2008. As a condition of approval, the FDA has requested a post-market trial. In collaboration with the FDA, Medtronic has designed a post-approval study to document the long-term performance of the Talent Stent Graft System under post market conditions.
This study will examine the post-market performance of the Talent Thoracic Stent Graft System. This study is a prospective, non-randomized five-year trial. Originally, a total of 451 subjects were going to be analyzed. That group consisted of 195 enrolled subjects from the VALOR Test Group of the Talent Thoracic PMA Submission, and 256 planned "de novo" subjects enrolled after the PMA approval. However, Medtronic discontinued manufacturing of the study device for US commercialization, and as a result, enrollment was terminated in May 2014, when it was determined that no more proximal devices were available either in inventory or at the sites. A total of 349 subjects will be analyzed, based on 195 VALOR Test Group subjects and 154 "de novo" subjects.
Update as of Aug 2017: Medtronic Vascular, Inc. discontinued manufacture of the Talent Thoracic Stet Graft System on 31-Jul-2012, and the final device expired in July 2014 (based on the two-year shelf life). Enrollment for De Novo subjects ended in May 2014, as there were no more proximal main devices available either in inventory or at the investigational sites. This resulted in a total of 349 subjects to be analyzed in this final report: the 195 VALOR subjects and 154 of the planned 256 De Novo subjects. Because of that, statistical results would have been inconclusive, so Medtronic decided to terminate the study and received FDA approval for early termination in April 2016.
It is important to emphasize that THRIVE subjects will continue to be followed-up annually per standard of care and standard post-market surveillance program applies to them (e.g. device complaints will continue to be reported via the MDR (Medical Device Reporting) system.)

Group Intervention Description DeNovo Talent Thoracic Stent Graft System Prospectively enrolled subjects treated with the Talent Thoracic Stent Graft System following U.S. market approval of the device.
- Primary Outcome Measures
Name Time Method Freedom From Aneurysm-related Mortality at 5 Years 5 years For all THRIVE subjects, Aneurysm-Related Mortality (ARM) is defined as: Death from rupture of the thoracic aortic aneurysm or from any procedure intended to treat the Descending Thoracic Aneurysm (DTA - fusiform aneurysms and saccular aneurysms/penetrating ulcers) as determined by an independent Clinical Events Committee (CEC). If a death occurred within 30 days of any procedure intended to treat the DTA, then it is presumed to be aneurysm related, unless there is evidence to the contrary.
