SIROLIMUS-COATED PTA · BTK · SFA · ILIAC
Sirolimus Coated Balloon for
Complex Peripheral Disease
MagicTouch PTA is a Sirolimus coated, polymer-free PTA balloon engineered for predictable drug
delivery in superficial femoral (SFA), popliteal, below-the-knee (BTK) and iliac artery. Powered by
Nanolute® Technology, it delivers sub-micron Sirolimus particles deeply into the vessel wall with
controlled release for up to 120 days.

SirPAD – randomized trial of Sirolimus-Coated Balloon vs Uncoated Balloon in infrainguinal artery disease
1252 patients (626 sirolimus-coated balloon; 626 uncoated balloon) with symptomatic infrainguinal artery disease were enrolled in a multicenter, prospective, randomized (1:1), open-label trial and followed for 1-year primary endpoint outcomes.

The SirPAD randomized trial, the world’s largest all‑comers PAD study, demonstrates that MagicTouch PTA sirolimus coated balloon angioplasty is both noninferior and superior to standard uncoated balloon angioplasty for the primary one‑year outcome of major adverse limb events.
Insights from the Principal Investigators
“We are excited about the primary outcome results of SirPAD. It is one of the very few trials in this field that successfully included an all-comers population, meaning consecutive patients without eligibility restrictions related to target-lesion characteristics or PAD stage. This led to nearly 50% of enrolled patients having acute or chronic limb-threatening ischemia, thereby providing enough events and statistical power to demonstrate superiority for hard clinical outcomes at one year.”

SIRONA – first RCT of Sirolimus DCB vs Paclitaxel DCB in SFA to prove non-inferiority
482 – patients (MagicTouch PTA 238 : Paclitaxel 244) to compare primary patency at 3 year in SFA disease, with additional clinical and safety endpoints.

36-month clinical outcomes from the world’s only head-to-head randomised controlled trial comparing Sirolimus vs Paclitaxel-coated balloons, demonstrating MagicTouch PTA superiority over Paclitaxel-coated balloons in SFA treatment for cd-TLR.
Presented at CX 2026.
SIRONA is the only head-to-head peripheral RCT comparing Sirolimus and Paclitaxel DCB, now extended to 3-year outcomes.
At 3 years:
- Improved outcomes in freedom from clinically driven TLR
- Comparable results in mortality and major amputation
HOPE BTK Registry – durable 3-year outcomes in high-risk CLTI patients
318 BTK patients (133 MagicTouch PTA; 185 POBA) with high prevalence of diabetes, advanced Rutherford class and elevated WIFI scores were followed to 3 years.

Overall Survival
In a challenging BTK CLTI population, MagicTouch PTA demonstrated improved freedom from TLR, superior amputation-free survival and better overall survival vs POBA at 3 years, with good limb preservation.
Key Takeaways
MagicTouch PTA, compared to POBA, was associated with lower BTK re-intervention, better AFS and survival rate. Long term sustained efficacy and safety upto 3 years indicate the superiority of MagicTouch PTA versus POBA in BTK
