Marking a major milestone in the advancement of new treatments for peripheral artery disease, Medtronic has announced the submission of its first pre-market approval (PMA) module to the US Food and Drug Administration (FDA) for the IN.PACT Admiral drug-eluting balloon. Designed to treat atherosclerotic lesions in the superficial femoral artery (SFA), the novel angioplasty device remains investigational in the United States.
"Pending FDA approval, we remain on track to launch the IN.PACT Admiral drug-eluting balloon in the United States during the second half of calendar year 2015," said Tony Semedo, president of Medtronic's Endovascular Therapies business. "In the meantime, we will continue working with leading healthcare providers and researchers around the world to amass clinical and economic evidence to support the global adoption of this innovative medical technology as an important addition to the treatment options for peripheral artery disease in the lower extremities."
The ongoing global clinical program of IN.PACT drug-eluting balloons for the treatment of peripheral artery disease in the lower extremities includes 24 studies involving more than 4,200 patients at approximately 230 sites worldwide. A combination of physician-initiated and company-sponsored studies, the program will fully characterize the safety and efficacy of these combination devices in a variety of peripheral vascular beds, including below-the-knee arteries.
Medtronic's PMA application for the IN.PACT Admiral drug-eluting balloon will include clinical data from the IN.PACT SFA I and SFA II pivotal studies, the IN.PACT SFA II pharmacokinetics (PK) study, and the IN.PACT Global study, which have enrolled a total of more than 1,000 patients to date.
IN.PACT drug-eluting balloons feature a proprietary coating called FreePac that is a formulation of the antiproliferative drug paclitaxel and the biocompatible excipient urea, which facilitates rapid absorption of the drug into the vessel wall.
Several IN.PACT drug-eluting balloons received the CE (Conformite Europeenne) mark in 2008 and 2009 and are available in many countries around the world. In the United States, the IN.PACT Admiral drug-eluting balloon is limited to investigational use under an investigational device exemption (IDE) granted by the FDA, and, like all drug-eluting balloons, is not yet commercially available.
The treatment of peripheral artery disease varies by stage of progression and other factors, with lifestyle modifications aimed at risk factor reduction recommended for all stages. Drug-eluting balloons represent a relatively recent addition to the procedural approaches, which also include atherectomy, balloon angioplasty and stenting. In cases involving especially long lesions, bypass surgery can create a new route for blood flow around the diseased artery.
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 oxygenated 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 growing global health concern, peripheral artery disease has increased in prevalence by nearly 24 percent worldwide over the most recent decade, from 164 million cases in 2000 to 202 million cases in 2010.1
