IN.PACT Admiral drug-coated balloon is approved in Japan


Medtronic announced on 8 September 2017 that the IN.PACT Admiral drug-coated balloon (DCB) received approval from the Japanese Ministry of Health, Labour and Welfare (MHLW) for the treatment of peripheral artery disease in the superficial femoral and popliteal arteries. Before Medtronic can begin commercialisation, it must partner with Japanese MHLW to gain reimbursement to ensure broader access to this therapy.

“The IN.PACT Admiral DCB has demonstrated superior one-year clinical outcomes in Japan and across Medtronic IN.PACT SFA clinical trials, providing patients with an improved restoration of blood flow and reduced need for additional revascularisation compared to plain balloon angioplasty, a current standard of care,” said Hiroyoshi Yokoi, Fukuoka Sannou Hospital, Japan. “In the IN.PACT SFA Japan Trial, the DCB demonstrated superior patency and lower reintervention rates. I look forward to treating peripheral arterial disease patients in Japan with this durable, consistent, and safe DCB technology.”

The MHLW granted approval for the IN.PACT Admiral DCB based on the clinical data from the IN.PACT SFA Japan Trial (MDT-2113 SFA Japan Trial) led by Osamu Iida, Kansai Rosai Hospital, Japan and Yokoi.

The study enrolled 100 patients across 11 sites in Japan and randomised treatment to either DCB (n=68) or plain balloon angioplasty (PTA) (n=32). The results were consistent with one-year findings from the pivotal IN.PACT SFA Trial, showing a consistently low clinically-driven target lesion revascularisation (CD-TLR) rate and high patency rate.

IN.PACT Admiral SFA Japan demonstrated 93.9% primary patency in the DCB group as compared to 46.9% in the PTA group at one year based on Kaplan-Meier Estimate (p<0.001). Additionally, one-year results demonstrated a CD-TLR rate of 2.9% for the DCB group compared to 18.8% in the PTA group (p=0.012). In IN.PACT SFA Japan, major adverse events were also lower for the DCB at one year (4.4% compared to 18.8% in the PTA group; p=0.028), with no major target limb amputations.

“Medtronic has long been committed to providing life-saving therapies to the more than 200 million patients suffering from peripheral arterial disease worldwide,” said Mark Pacyna, vice president and general manager of the Peripheral business in the Medtronic Cardiac & Vascular Group. “IN.PACT Admiral was launched more than seven years ago in Europe. Now, with more than 200,000 patients treated, we are excited to bring IN.PACT Admiral DCB to patients in Japan.”

The IN.PACT Admiral drug-coated balloon is a clinically-proven primary endovascular therapy. It has been approved in Japan to treat de novo and non-stented restenotic lesions with length ≤200mm in superficial femoral and popliteal arteries with reference vessel diameters of ≥4mm and ≤7mm. The DCB’s primary mode of action is physical dilatation of the vessel lumen by PTA, and the proven paclitaxel drug is intended to prevent artery narrowing by minimising scar tissue formation.
