On 15 August, Medtronic announced the submission of its first pre-market approval (PMA) module to the FDA for the In.pact Admiral drug-eluting balloon. Designed to treat atherosclerotic lesions in the superficial femoral artery, the novel angioplasty device remains investigational in the USA.
“Pending FDA approval, we remain on track to launch the In.pact Admiral drug-eluting balloon in the USA 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 arterial disease in the lower extremities.”
The ongoing global clinical programme of In.pact drug-eluting balloons for the treatment of peripheral arterial 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 programme will fully characterise 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 mark in 2008 and 2009 and are available in many countries around the world. In the USA, the In.pact Admiral drug-eluting balloon is limited to investigational use under an investigational device exemption granted by the FDA, and, like all drug-eluting balloons, is not yet commercially available.
