Prospective, Pivotal, First - in Man Clinical Trial of the Safety and Efficacy of a Novel Microcrystalline Paclitaxel Coated Balloon for Treatment of Femoropopliteal Artery Disease
The purpose of this pivotal, first in man study will be to evaluate safety and efficacy of the novel, microcrystalline paclitaxel coated balloon (mcPCB, PAK, Balton) in the treatment of femoropopliteal artery disease.
Although clinically effective, the manufacturing process of first generation PCB coatings contributed to inconsistent drug concentrations, particulate formations on the balloon surface and their shedding during the interventional procedures. As a consequence developments of new PCB coatings have been proposed to address consistency, uniformity, small particle drug coverage, which may potentially contribute to improved vessel healing profile and improved clinical outcomes. Nevertheless, data on the safety and efficacy of this novel coating developments in the clinical setting remain limited. Previously in the experimental model, the investigators reported that delivery of paclitaxel via a novel mcPCB resulted in low long-term tissue retention of paclitaxel, however displayed reduced neointimal proliferation and favorable healing profile. Therefore in current clinical trial the investigators will address the feasibility and safety of the mcPCB (PAK, Balton) in the treatment of femoropopliteal restenotic disease in a prospective, randomized manner when compared to plain balloon angioplasty (PBA). The efficacy analysis will be observational and evaluated post-hoc, with no prespecified criteria.
