FDA approves Intact Vascular’s Tack dissection repair device

The FDA last week granted pre-market approval to the Tack endovascular repair device developed by Intact Vascular.

The Wayne, Pa.-based company’s Tack system is designed to repair dissection complications during balloon angioplasty for peripheral artery disease. Intact said the federal safety watchdog based the April 11 PMA decision on the results of a pivotal, 213-patient single-arm trial that met both its safety and efficacy endpoints. The Tack device won CE Mark approval in the European Union in January 2017.

The Toba II study‘s rate of freedom from clinically-driven target lesion revascularization, amputation or all-cause death, its primary safety endpoint, was 86.5%. The trial met its efficacy endpoint with a 79.3% primary patency rate at 12 months. And 92.1% of all dissections were completely resolved, according to results presented at last year’s Vascular InterVentional Advances conference in Las Vegas by principal investigator Dr. William Gray.

Intact Vascular said the trial, which it touted as the first to enroll PAD patients with 100% dissected vessels, also showed 0.5% bailout stent rate and zero implant fractures.

“FDA approval of the Tack endovascular system comes at a dynamic time in the PAD market place. The Tack system’s unique combination of minimal metal and highly targeted dissection repair is an ideal fit with today’s focus on minimizing inflammation and improving long term outcomes,” president & CEO Bruce Shook said in prepared remarks. “Now with the Tack endovascular system available in both Europe and the United States, we look forward to expanding our commercialization efforts and continuing to improve the quality of life for PAD patients.”

“I look forward to having the Tack implant available for my patients,” added Gray, of Wynnewood, Pa.’s Lankenau Heart Institute. “Post-angioplasty dissections can significantly impact patient outcomes. Having a minimal metal solution that specifically addresses dissections and improves angioplasty results while preserving future treatment options is extremely exciting.”

Intact said it’s planning a limited U.S. release “that will progress toward broader market commercialization.” The company raised a $20 million Series C round in April 2018.
