Abstract
BACKGROUND Drug-coated balloons (DCB) have shown promising results for the treatment of in-stent restenosis (ISR) and small vessel disease (SVD). However, data comparing the treatment efficacy of different DCBs are limited.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). CONCLUSIONS Data from this study demonstrate good clinical outcomes with the Agent DCB when used to treat patients with SVD or ISR.

Abstract
The role of drug-coated balloons (DCBs) in patients with acute myocardial infarction (AMI) remains controversial. We performed a meta-analysis of all published studies comparing the outcomes of DCBs vs. stenting in AMI patients. Four studies with 497 patients (534 lesions) were included (three randomized controlled trials and one observational study). During a mean follow-up of 9 months (range 6-12 months), DCBs were associated with similar risk of major adverse cardiovascular events (5% vs. 4.4%; OR 1.24, 95% CI: [0.34, 4.51], p = 0.74, I2 = 35%), all-cause mortality (0.02% vs. 0.04%; OR 077, 95% CI: [0.15, 3.91], p = 0.75, I2 = 25%), cardiac death (0.01% vs. 0.02%; OR 0.64, 95% CI: [0.16, 2.64], p = 0.54), myocardial infarction (0% vs. 1.4%; OR 0.18, 95% CI: [0.01, 3.56], p = 0.26), and target lesion revascularization (3.7% vs. 2%; OR 1.74, 95% CI: [0.42, 7.13], p = 0.44, I2 = 17%) compared with stenting. During a mean follow-up of 7 months (range 6-9 months), DCBs had similar late lumen loss compared with stenting (mean difference 0.04 mm, 95% CI [- 0.21-0.28], p = 0.77, I2 = 92%). In patients with AMI, there was no statistical difference in the incidence of clinical and angiographic outcomes between AMI patients treated with DCB and DES. Larger studies with longer-term follow-up are needed to assess the clinical utility of DCBs in this setting.
