New sirolimus balloon takes on paclitaxel in leg artery showdown
NCT ID NCT07359807
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two drug-coated balloons for treating narrowed or blocked arteries in the leg. The experimental balloon uses sirolimus, a drug that stops cells from growing and blocking the artery again, while the standard balloon uses paclitaxel. About 478 people with leg artery disease will be randomly assigned to one of the two balloons. The main goal is to see if the sirolimus balloon keeps arteries open just as well as the paclitaxel balloon after one year, with fewer complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sirolimus (drug-coated balloon)
- What this could lead to
- If it works, this could offer a better option for opening blocked leg arteries, potentially reducing the need for repeat procedures.
- What could go wrong
- This is an early-to-mid-stage trial (Phase 2/3) with 478 participants, so results may not apply to everyone. The sirolimus balloon might not be as effective or safe as the standard paclitaxel balloon.

Inclusion Criteria: * Subject age ≥ 21 years * Subject has been informed of the nature of the trial, the duration of the trial, agrees to attend follow-up visits, agrees to complete the required testing, agrees to participate, and has signed an informed consent form. * Rutherford category 2-4 according to the investigator's subjective evaluation * Subject has de-novo or re-stenosed lesion with ≥ 70% stenosis documented angiographically, and no prior stent in the target lesion. * Target lesion length is ≥ 40mm and ≤ 200mm by visual estimate of the treating physician. * Multiple lesions with max. A 30mm healthy vessel segment between lesions can be considered, at the treating physician's discretion, as one lesion. Total lesion length should not exceed 200mm. * Reference vessel diameter (RVD) ≥ 4mm and ≤ 7 mm by visual estimation. * Patency of P2 and P3 segments of the popliteal artery and at least one (1) infra-popliteal artery to the ankle (\< 50% diameter stenosis) in continuity with the femoropopliteal artery. * Patency of the ipsilateral iliac artery (≤ 30% diameter stenosis). Iliac artery stenosis \> 30% may be treated during the index procedure to ensure sufficient inflow. * Staged Intervention of the contralateral limb is permitted at +/- 30 days. * A subject can only be enrolled and randomized once with only one target lesion in the MAGICAL SFA trial. Note that only the lesion in one limb can be treated as a target lesion for the index procedure. Exclusion Criteria: * Failure of the guidewire to successfully cross the target lesion or subintimal target lesion. * Flow-limiting dissection after pre-dilatation and/or residual stenosis \> 30% prior to randomization. * Angiographic evidence of severe calcification of the target vessel (contiguous calcification on both sides of the vessel). * Presence of fresh/organized thrombus in the target lesion. * Presence of aneurysm in the target vessel/s. * Prior vascular surgery (including atherectomy , bypass surgery) of the target limb. * Prior stent in the target lesion. * Stroke or heart attack within three months prior to enrollment. * Any vascular surgical procedure or intervention performed in the target limb within 30 days prior to or planned within 30 days post index procedure. * Any vascular treatment with PTX or sirolimus-coated devices 60 days prior to the index procedure. * Target lesion requires treatment with alternative therapies such as primary stenting, laser, lithotripsy, thrombectomy, atherectomy, and/or cryoplasty brachytherapy re- entry devices. * Enrolled in another investigational drug, device, or biologic trial where the primary end point is not yet achieved. * Life expectancy of less than one year in the investigator's opinion. * Known allergies or sensitivity to heparin, aspirin, other anticoagulant/antiplatelet therapies, sirolimus, paclitaxel, or contrast media that cannot be adequately pre- treated prior to index procedure. * Significant gastrointestinal bleeding or any coagulopathy that would contraindicate the use of anti-platelet therapy. * Receiving dialysis or immunosuppressant therapy . (A systemic corticosteroid therapy with expected maximum dosage of 5mg prednisolone or equivalent, per day, during the initial 9 months after procedure, is allowed.) * Subjects with severe (Stage 4) renal disease, defined as eGFR \< 30%. * Pregnant or lactating females . * History of major amputation in the target lesion limb.
