The BRight PK Study is a prospective, single-arm, open-label, non-blinded, non-randomized study, which goal is to assess the pharmacokinetic profile of the BRight drug-coated balloon at different time points after the balloon deployment.
The study will enroll a maximum of 10 patients at a single site in Australia

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| BRight DCB | Experimental | Single arm study. All subjects will be treated with the BRight DCB |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| BRight DCB | Device | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| AUC 0-t | Area under the drug concentration-time curve, calculated using linear trapezoidal summation from time zero to time tlast, where tlast is the time of the last measurable concentration (Ct). | 0 to 24 hours |
| AUC 0-inf | Area under the drug concentration-time curve from time zero to infinity | 0 to 24 hours |
| Cmax | Maximum observed drug concentration | 0 to 24 hours |
| Terminal Elimination Rate Constant (λz) | Apparent terminal elimination rate constant, calculated by linear regression of the terminal linear portion of the log concentration vs. time curve | 0 to 24 hours |
| Terminal Elimination Half-life (t1/2) | Apparent terminal elimination half-life, calculated as ln(2)/λz | 0 to 24 hours |
| tmax | Time of the maximum drug concentration (obtained without interpolation). If the maximum value occurs at more than one time point, tmax is defined as the first time point with this value. | 0 to 24 hours |
| Drug clearance (CL) | Apparent total clearance, calculated as dose/AUC0-inf | 0 to 24 hours |
| Apparent volume of distribution at the terminal phase (Vz) |
| Measure | Description | Time Frame |
|---|---|---|
| Device success | Successful delivery, balloon inflation/deflation and retrieval of the intact trial device | 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 |

Inclusion Criteria:
The subject has provided written informed consent
The subject is willing to participate in the clinical investigation and to comply with the study procedures and follow-up visits
Lifestyle-limiting claudication or rest pain requiring treatment of superficial femoral (SFA) and/or proximal popliteal artery (PPA)
Age ≥ 18 years old
Rutherford-Becker Clinical Category of 2, 3 or 4
Target vessel reference diameter ≥5 mm and ≤ 6 mm (by visual estimation)
De novo lesion with >50% stenosis by operator visual estimate within the SFA and/or proximal popliteal arteries in a single limb.
Lesion must be located ≥ 1 cm below the Common Femoral Artery (CFA) bifurcation and terminate distally at ≥ 3 cm proximal to the knee joint (radiographic joint space).
Single lesion length ≤170 mm for de novo stenotic lesions, or ≤ 100 mm for occluded lesions (one long lesion or multiple serial lesions) by operator visual estimate. Notes: (1) Only 1 lesion per patient can be treated. Multiple serial lesions are allowed if they can be treated as a single lesion with a maximum of 2 balloons. (2) a non-occlusive lesion that includes a totally occluded segment along its length are eligible provided that the overall treated lesion length is ≤170 mm (with / or without an occluded segment not greater than 100 mm in length).
Successful guidewire crossing of lesion.
After pre-dilatation, the target lesion is ≤ 30% residual stenosis with no flow limiting dissection and treatable with a maximum of 2 balloons.
Inflow artery is patent, free from significant lesion stenosis (>50% stenosis considered significant) as confirmed by angiography.
Note: Where required, inflow iliac arteries (common and external iliac arteries only) must be successfully treated during the index procedure. Completion angiography must confirm successful treatment of inflow disease (≤50% residual stenosis, no distal embolization, and no Grade C or greater dissection) prior to pre-dilatation of the target lesion. Drug-eluting devices are not allowed for treatment of the occluded inflow iliac arteries.
Patency of the popliteal segments P2 and P3 with at least 1 patent infrapopliteal run-off vessel (that may have a stenosis of less than 50% not interfering with the outflow to the pedal arch) to the ankle in continuity with the native femoropopliteal artery, in the target limb confirmed at baseline. (Note: treatment of outflow disease is permitted. Drug-eluting devices are not allowed for outflow treatment)
