SIRONA completes enrollment - A leap in the DCB treatment of femoropopliteal arterial disease
TAMPA, Fla., Oct. 21, 2022 /PRNewswire-AsiaNet/ --

    Concept Medical Inc. [https://www.conceptmedical.com/] announces the 
successful completion of the SIRONA - World's first and the largest 
head-to-head RCT investigating the use of Sirolimus Drug Coated Balloon (DCB) 
(Magic Touch PTA [https://www.conceptmedical.com/product/magic-touch-pta/] – 
Concept Medical Inc.) V/S Paclitaxel DCB angioplasty for the treatment of 
peripheral artery disease in the femoropopliteal vessel segment.

    The prospective, multi-center, head-to-head, corelab adjudicated RCT 
enrolled a total of 480 patients across 28 sites in Germany and Austria. The 
target patient was enrolled on September 23, at Hanusch Hospital Vienna by PI 
Prof. Martin Werner and team.

    Prof. Dr. Ulf Teichgräber states, "As coordinating PI I am thrilled to work 
with 28 highly dedicated and motivated study sites that have managed to 
complete enrollment much earlier than expected. SIRONA represents a 
breakthrough head-to-head RCT with the potential to usher in a new era of 
Sirolimus DCB in PAD to replace an old technology."

    Plain Old Balloon Angioplasty (POBA) has been the go-to treatment option, 
followed by Paclitaxel DCB - with discouraging success due to FDA concerns and 
controversies over safety of Paclitaxel. Sirolimus DCB treatment is well 
established as a safe and effective option in both coronary and peripheral 
artery disease segments. Concept Medical's Magic Touch PTA Sirolimus Coated 
Balloon has been tested with good success in both safety and efficacy criteria 
in lower extremity diseases across multiple studies. Furthermore, the device is 
also being compared directly against POBA in other RCT, but what was required 
was a head on RCT against paclitaxel, to add weight to it being the better 
option.

    SIRONA will be a game changer trial, considering its bold design and the 
direct comparison against paclitaxel. The trial enrolled all patients with a 
disease in the SFA segment, whether de-novo or restenotic, falling into 
Rutherford classes 2-4, and experiencing intermittent claudication to Critical 
Limb Ischemia (CLI). The 12 months result will feature patency (defined as the 
absence of TLR or restenosis), and primary safety endpoint is assessed as the 
composite of freedom from device or procedure-related death at 12 months as 
well as major target limb amputation. The complete credit extends to all the 
site investigators, operators, technicians and CRO for a swift and seamless 
enrollment and the results are much awaited.

    The University Heart Center - Bad Krozingen topped the enrollment under the 
lead of Prof. Thomas Zeller.

    "It is exciting that enrollment into the first head-to-head comparative 
study between a sirolimus coated DCB and a variety of marketed paclitaxel 
coated DCB for femoropopliteal indication could be finished in such a short 
time. The study has sufficient size and the power to demonstrate if there is at 
least equivalent performance between the Magic Touch DCB and a range of 
paclitaxel coated DCB and if so, if there are potential lesions which may even 
benefit from the use of a sirolimus coated DCB," adds Prof. Thomas Zeller on 
this achievement.

    Magic Touch PTA [https://www.conceptmedical.com/product/magic-touch-pta/] 
has already been granted a breakthrough device designation by the US FDA for 
BTK indication and has a head-to-head RCT ongoing as well against paclitaxel. 
The results from SIRONA, will surely play a significant role in shifting the 
scale towards Sirolimus and a perspective and opinion shift for the fraternity, 
if not less.
