The primary aim of this clinical study is to assess the safety and clinical performance of the BRight drug-coated balloon (DCB) in the treatment of lower limb arteries stenosis in subjects with Peripheral Artery Disease (PAD). The primary endpoint will be Late Lumen Loss (LLL) of the target lesion at 6 months.

The BRight Drug-Coated Percutaneous Transluminal Angioplasty (PTA) Balloon catheter (BRight DCB) is intended for dilatation of de novo lesions in native superficial femoral or popliteal arteries with a simultaneous release of drug to the vessel wall as a secondary action to reduce occurrence of a restenosis of the treated vessel segment.

Late Lumen Loss
Late Lumen Loss, as measure by quantitative vascular angiography (QVA)
Time frame: 6 months post index procedure
Device success
Successful delivery, balloon inflation/deflation and retrieval of the intact trial device
Time frame: during procedure
Acute technical success
Successful vascular access and completion of the endovascular procedure and immediate achievement of a final residual diameter stenosis of ≤30% of the treated lesion by core laboratory assessed QVA on the completion angiography with no bailout stenting
Time frame: during procedure
Acute procedural success
Technical success without the occurrence of death, major target limb amputation, thrombosis of the target lesion, or clinically-driven TLR within 72 hours of the index procedure
Time frame: 72 hours post index procedure
Major Adverse Event (MAE) rate
MAE is a composite of device or procedure related death within 30 days post index procedure, major index limb amputation, cd TLR
Time frame: 1, 6 and 12 months post index procedure
Clinically-driven Target Lesion Revascularization (cd TLR) rate
cd TLR is defined as any repeat intervention of the target lesions or surgical bypass of the target vessel performed for restenosis \> 50% or other complication involving the target lesion, after documentation of recurrent clinical symptoms of the patient.
Time frame: 1, 6 and 12 months post index procedure
Clinically-driven Target Vessel Revascularization (cd TVR) rate

Time frame: 1, 6 and 12 months post index procedure
Target lesion Binary Restenosis
Defined as duplex ultrasound peak systolic velocity ratio (PSVR) \> 2.5 (if DUS is completed) or angiographic assessment which suggests stenosis \> 50% by QVA
Time frame: 1, 6 and 12 months post index procedure
Target lesion primary patency
Target lesion primary patency defined as duplex ultrasound peak systolic velocity ratio (PSVR) ≤ 2.5 (if DUS is completed) or angiographic assessment which suggests stenosis ≤ 50% by QVA and the absence of Clinically-driven TLR (adjudicated by a CEC)
Time frame: 1, 6 and 12 months post index procedure
Change in the Walking Impairment questionnaire (WIQ) as compared to baseline
change in WIQ between baseline and follow-up
Time frame: 1, 6 and 12 months post index procedure
Embolic event of the index limb
occurrence of embolic event as visualized on angiography
Time frame: during procedure
