To assess the longer-term safety and efficacy of the IN.PACT Admiral (MDT-2113) drug-coated balloon (DCB) for the treatment of de novo and non-stented restenotic lesions in the superficial femoral and/or proximal popliteal arteries versus uncoated percutaneous transluminal angioplasty (PTA) in a Japanese cohort.
Although DCBs are the newest endovascular strategy for patients with peripheral artery disease presenting with femoropopliteal lesions, there remains a paucity of results in non-Caucasian populations.
IN.PACT SFA Japan is an independently-adjudicated, prospective, multicenter, randomized, single-blinded trial. Endpoints through 2 years included primary patency and a composite safety endpoint of freedom from device- and procedure-related death through 30 days, freedom from target limb major amputation and freedom from clinically-driven target vessel revascularization at 24 months.
One hundred patients were assigned by 2:1 randomization to treatment with the IN.PACT Admiral DCB (n = 68) or PTA (n = 32). The groups were well-matched at baseline. Mean lesion length for the DCB and PTA groups were 9.15 ± 5.85 and 8.89 ± 6.01 cm (P = 0.838), respectively. Patients treated with DCB exhibited superior 24-month primary patency compared to PTA (79.8% vs. 46.9%; log rank P < 0.001). The 24-month clinically driven target lesion revascularization rate was 9.1% for DCB versus 20.7% for PTA (P = 0.177). There were no device- or procedure-related deaths, major amputations, or thromboses in either group.
Two-year results from IN.PACT SFA Japan demonstrated persistently superior patency and low CD-TLR rates through 2 years when compared to uncoated PTA in Japanese patients. These data are consistent with other IN.PACT DCB trials.
评估 IN.PACT Admiral(MDT-2113)药物涂层球囊(DCB)在日本队列中用于治疗新出现的和非支架再狭窄病变的股浅动脉和/或腘动脉与未涂层经皮腔内血管成形术(PTA)的长期安全性和疗效。
尽管 DCB 是外周动脉疾病患者股腘病变的最新血管内治疗策略,但在非高加索人群中的结果仍然很少。
IN.PACT SFA Japan 是一项独立评估、前瞻性、多中心、随机、单盲试验。2 年的终点包括主要通畅率和复合安全终点,即 30 天内无器械和手术相关死亡、无靶肢体主要截肢和 24 个月内无临床驱动的靶血管血运重建。
100 例患者按 2:1 随机分为 IN.PACT Admiral DCB 治疗组(n=68)和 PTA 治疗组(n=32)。两组基线匹配良好。DCB 和 PTA 组的平均病变长度分别为 9.15±5.85cm 和 8.89±6.01cm(P=0.838)。DCB 治疗组 24 个月的主要通畅率优于 PTA 组(79.8% vs. 46.9%;对数秩检验 P<0.001)。24 个月时 DCB 的临床驱动的靶病变血运重建率为 9.1%,而 PTA 组为 20.7%(P=0.177)。两组均无器械或手术相关死亡、主要截肢或血栓形成。
IN.PACT SFA Japan 的 2 年结果显示,与未涂层 PTA 相比,日本患者的通畅率持续更高,2 年内 CD-TLR 率更低。这些数据与其他 IN.PACT DCB 试验一致。
