The FDA has approved the IN.PACT Admiral drug-coated balloon (DCB) to treat long superficial femoral artery (SFA) lesions up to 360 mm in patients with peripheral artery disease, according to Medtronic.
The approval was issued as a result of data from the complex lesion imaging cohorts of the IN.PACT Global study, which included long lesion, in-stent restenosis, and chronic total occlusion groups with lesion lengths >180mm. Data from a total of 227 patients with mean lesion lengths of 28.7 ± 7.1 cm were analyzed, and results indicated a patency rate of 89.1% at day 360. Additionally, there was a clinically-driven target revascularization rate of 7.1%.
"Data from the IN.PACT Global Study demonstrate that IN.PACT Admiral DCB is a safe and effective treatment option in real-world patients with lesions beyond 180 mm, frequently comprised of in-stent restenosis and chronic total occlusions," Daniel Clair, MD, said in a press release from Medtronic. Dr. Clair is chair of the Department of Surgery for University of South Carolina (USC) and the Palmetto Health-USC Medical Group. He added, "More specifically, these results show maintenance of strong clinical outcomes, including a high primary patency rate and limited need for reintervention in patients exhibiting these complex, long lesions - among the most prevalent cases we see. The FDA's approval of this expanded indication now offers U.S. physicians a clinically-proven endovascular therapy to address this critical patient need."
According to an overview issued by FDA, the device should not be used in the following situations:
- Patients with narrowed arteries in the heart, kidneys, or brain.
- Patients who cannot take recommended medicines that thin the blood and prevent blood clots.
- Patients with a lesion that prevents complete inflation of an angioplasty balloon or proper placement of the delivery system.
- Patients with a known hypersensitivity to paclitaxel or drugs with similar characteristics as paclitaxel.
- Women who are breastfeeding, pregnant, or intend to become pregnant; or men intending to father children.
