Medtronic reaches major milestone in clinical programme for In.pact Admiral drug-eluting balloon

223

On 3 June 2013, Medtronic announced that enough patients have been enrolled in its clinical studies of the In.pact Admiral drug-eluting balloon to support the company’s US regulatory approval submission of the novel angioplasty device, which is designed to treat atherosclerotic lesions in the superficial femoral artery. 

In a related development, Medtronic also announced that it plans to submit the first module of the pre-market approval (PMA) application for the In.pact Admiral drug-eluting balloon to the FDA over the summer.

“The In.pact Admiral drug-eluting balloon represents a novel angioplasty device from Medtronic that we foresee launching in the United States in late 2015, pending FDA approval,” said Tony Semedo, president of Medtronic’s Endovascular Therapies business. “It targets atherosclerotic lesions in the superficial femoral artery with a treatment modality that aims to deliver an anti-restenotic drug while leaving nothing behind.”

More than 1,000 patients have been enrolled in the IN.PACT SFA I, II, II pharmacokinetics (PK) and Global studies to date. Clinical data from these studies will comprise a significant portion of Medtronic’s PMA application to the FDA for the IN.PACT Admiral drug-eluting balloon. IN.PACT SFA I is a European study; IN.PACT SFA II and II PK, both US studies; and IN.PACT Global, an international study being conducted outside the United States.

The ongoing global IN.PACT clinical programme includes 29 studies involving more than 4,600 patients at approximately 230 sites worldwide. Through these company-sponsored and physician-initiated studies, Medtronic’s portfolio of IN.PACT drug-eluting balloons will be investigated thoroughly for the treatment of arterial disease in a variety of vessel beds. As part of this programme, Medtronic is currently enrolling the IN.PACT Global study, a first-of-its-kind, “real-world” evaluation of the company’s IN.PACT drug-eluting balloons involving 1,500 patients with femoropopliteal lesions of any length at up to 80 sites worldwide. 

IN.PACT drug-eluting balloons feature a proprietary coating called FreePac that is a formulation of paclitaxel and urea, an excipient that facilitates absorption of the drug into the vessel wall. They received the CE 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 every drug-eluting balloon, is not yet commercially available.
