FDA Approves Medtronic, Inc.'s Complete "SE" Vascular Stent

FDA Approves Medtronic's Complete 'SE' Vascular Stent for Use in Superficial Femoral and Proximal Popliteal (Leg) Arteries

MINNEAPOLIS -- September 24, 2013 -- Expanding its role in the treatment of peripheral artery disease in the United States, Medtronic, Inc. (NYSE: MDT) announced today that the U.S. Food and Drug Administration (FDA) has approved the Complete SE (self-expanding) vascular stent for use in the lower extremities -- specifically, the superficial femoral artery (SFA) and proximal popliteal artery (PPA), which carry blood through the upper legs.

The same device was originally approved by the FDA for use in the iliac arteries, which perfuse the pelvis. It also has the CE (Conformité Européene) mark for iliac and, most recently, for SFA and PPA indications.

FDA approval of the new SFA and PPA indications was supported by the results of the Complete SE SFA study -- an independently adjudicated single-arm, multicenter trial that enrolled 196 patients at 28 sites in the United States and Europe. The study showed a clinically-driven target lesion revascularization (repeat procedure) rate of 8.4 percent at 12 months, which is among the best performances in clinical trials of contemporary self-expanding peripheral stents for the treatment of SFA/PPA lesions.

Additionally, there were no in-hospital major adverse events (MAE) among study patients, and the total MAE rate at 12 months was 11.0 percent. The Kaplan-Meier estimate of primary patency at 360 days was 90.9 percent; at the time of the last duplex ultrasound assessment, at 553 days, primary patency was 72.5 percent. No stent fractures occurred through 12 months.

The study also showed statistically significant improvements in multiple measures of clinical and functional effectiveness:

More than 80 percent of the patients had achieved a Rutherford classification of 0 or 1, the favorable end of the 0-6 scale, at 30 days, and that benefit persisted through six months and one year of follow-up.

On walking assessment measures at 12 months, absolute improvement in impairment was 37 percent, distance was 32 percent, speed was 22 percent and stair climbing was 23 percent.

65 percent of the patients showed an improvement of 0.15 or more on their ankle-brachial index (ABI) or toe-brachial index (TBI) scores over the 12-month follow-up period. The mean ABI/TBI score at 12 months was 0.9.

These outcomes were achieved despite the challenging nature of the patient population:

45 percent of the patients had diabetes, and 67 percent had a Rutherford classification of 3 or higher at baseline.

50 percent of the treated lesions were located in the distal segment of the artery, and 91 percent were moderately or highly calcified.

"The Complete SE vascular stent has demonstrated compelling clinical results in this study, which included a broad spectrum of patient and lesion types," said primary investigator Dr. John Laird, medical director of the UC Davis Vascular Center near Sacramento. "It is also among the most deliverable and easy-to-use devices of its kind."

With risk factors including smoking, diabetes, obesity, high blood pressure, high cholesterol, age (50 or older) and familial history, peripheral artery disease narrows the vessels that supply blood to the body, especially the limbs. Typically characterized by an excessive buildup of plaque in these vessels, the condition can progress to claudication and, without treatment, to critical limb ischemia, which often leads to amputation and premature death.

A variety of treatments are used to restore normal blood flow in patients with peripheral artery disease. Stents are metallic scaffolds used to improve blood flow by expanding the interior diameter of narrowed arteries. These tubular medical devices are implanted in a minimally invasive procedure that uses catheters to access the arterial segment requiring treatment.

In collaboration with leading clinicians, researchers and scientists, Medtronic offers the broadest range of innovative medical technology for the interventional and surgical treatment of cardiovascular disease and cardiac arrhythmias. The company strives to offer products and services that deliver clinical and economic value to healthcare consumers and providers worldwide.
