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=KYODO JBN/ --
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."
