Methods and Results: AGENT Japan is a prospective randomized controlled trial that compares the Agent balloon coated with a low-dose formulation of paclitaxel (2 μg/mm2) to the SeQuent Please paclitaxel-coated balloon (3 μg/mm2) for the treatment of SVD. Patients with target lesion length ≤28 mm and reference diameter between ≥2.00 and <3.00 mm were randomized 2 : 1 for treatment with Agent (n=101) or SeQuent Please (n=49). This trial also includes a separate single-arm substudy evaluating the clinical safety and effectiveness of Agent in patients with ISR. The primary endpoint of 6-month target lesion failure (TLF) was observed in 3.0% of Agent and 0.0% of SeQuent Please patients (difference=3.0%; 97.5% upper confidence bound [UCB]=9.57%, which is less than the prespecified margin of 13.2%; Pnon-inferiority=0.0012). There were no deaths or thrombosis, and angiographic and quality-of-life outcomes were comparable between groups. The AGENT Japan ISR substudy (n=30) primary endpoint was met because the one-sided 97.5% UCB for 6-month TLF (3.3%) was significantly less than the study success criterion of 15.1% (97.5% UCB=9.8%; P<0.0001).
