SIRONA - The world's first and largest RCT comparing Sirolimus V/S Paclitaxel balloon for the treatment of Peripheral Arterial Disease progresses rapidly
JENA, Germany, May 25, 2021 /PRNewswire-AsiaNet/ --

    Concept Medical Inc. [https://www.conceptmedical.com/ ], focused on 
vascular intervention drug delivery devices, releases status updates of SIRONA 
Randomized Control Trial (RCT) which compares head-to-head, SIROlimus versus 
Paclitaxel Drug-Eluting BallooN Angioplasty in femoropopliteal arterial 
diseases (SIRONA). 

    SIRONA is the world's first RCT investigating the use of Sirolimus drug 
coated balloon (DCB) (MagicTouch PTA 
[https://www.conceptmedical.com/product/magic-touch-pta/ ] – Concept Medical) 
V/S Paclitaxel DCB for the treatment of femoropopliteal artery disease.

    SIRONA is an Investigator-Initiated and driven, prospective, multi-center, 
corelab adjudicated randomized trial to compare and evaluate the safety and 
efficacy of Sirolimus Coated balloon versus Paclitaxel Coated Balloon (CE 
certified devices) in the treatment of stenosed or occluded lesions in the 
superficial femoral artery (SFA), and/or popliteal artery (P1) in Peripheral 
Arterial Disease (PAD) patients with Rutherford classification 2 to 4. The 
study will enroll a total of 478 patients randomized 1:1 (MagicTouch 
PTA:Paclitaxel Coated Balloon) across 30 sites in Germany and Austria. Led by 
the Principal Investigator Prof. Dr. Ulf Teichgraber, of Jena University 
Hospital, Germany, the study is moving rapidly with 20 patients already 
enrolled.

    Lower extremity PAD affects estimated quarter million adults in Europe and 
North America and is associated with significant morbidity and mortality, with 
atherosclerosis being the main cause. Symptomatic PAD presents as claudication 
and can progress into Critical Limb Ischemia (CLI), pointing at 20% mortality 
in the first five years and the rate increasing to 50% post five years.

    Percutaneous Transluminal Angioplasty (PTA) with plain old balloon 
angioplasty (POBA) has been widely used as the treatment which involves 
expansion of the arteries with an uncoated balloon, but with limited success, 
as many patients come back with restenotic or occluded lesions. Drug eluting 
stents have been used in the past with anti-proliferative drugs which reduces 
the neointimal hyperplasia and stenosis to some extent. DCBs have been used to 
effectively treat the stenosed SFA with similar drugs (Paclitaxel and Limus 
analogues) recently and are becoming the go to option. Currently, the 
commercially available DCBs for peripheral arteries are coated with Paclitaxel. 
Given all the safety issues with Paclitaxel, there is need to explore other 
drugs to replace Paclitaxel.  

    The primary objective of the SIRONA 
[https://www.conceptmedical.com/press-release/sirona-rct-update/ ] trial is to 
determine the safety and efficacy of Sirolimus Coated Balloon application in 
SFA with the primary endpoint of patency at 12 months defined as absence of TLR 
or restenosis and primary safety endpoint determined as composite of freedom 
from device or procedure related death at 12 months as well as major target 
limb amputation. The trial will include all patients with a disease in the SFA 
segment either de-novo or restenotic, falling under Rutherford class 2-4 and 
suffering from intermittent claudication to CLI. 

    In the past, Paclitaxel Coated Balloon has been used, with limited success, 
in the treatment of femoropopliteal arteries in PAD. SIRONA trial is currently 
the first trial worldwide that is ongoing to collect additional evidence on 
patient safety with a head-to-head comparison of Sirolimus Coated Balloon 
(MagicTouch PTA [https://www.conceptmedical.com/product/magic-touch-pta/ ]) and 
Paclitaxel Coated Balloon. MagicTouch PTA has been assigned a breakthrough 
device designation by the US FDA for BTK indication. 

    Prof. Dr. Ulf Teichgraber shows his optimism regarding the trial with a 
positive note, "I believe that SIRONA will be a game changer trial by giving 
new evidence on how to perform PTA following the principle of nothing leaving 
behind."
