This clinical trial will serve as a first-in-human (FIH) experience for the BA9™ DCB in a population of patients with coronary artery disease who have an indication for interventional treatment of in-stent restenosis (ISR) in a bare-metal stent (BMS) or drug-eluting stent (DES).~The study uses a prospective, multi-center, single blind, randomized controlled trial design to enroll 195 patients. The study will seek to prove that the BA9-DCB is non-inferior to the approved CE marked Sequent Please® Paclitaxel Coated Balloon with respect to % Diameter Stenosis and has similar safety characteristics.
The study is a Prospective, Randomized, Non-Inferiority Trial to Determine the Safety and Efficacy of the BA9™ Drug Coated Balloon for the Treatment of In-Stent Restenosis. It is a First-in-Man Trial.
