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

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.

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).
Time frame: 0 to 24 hours
AUC 0-inf
Area under the drug concentration-time curve from time zero to infinity
Time frame: 0 to 24 hours
Cmax
Maximum observed drug concentration
Time frame: 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
Time frame: 0 to 24 hours
Terminal Elimination Half-life (t1/2)
Apparent terminal elimination half-life, calculated as ln(2)/λz
Time frame: 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.
Time frame: 0 to 24 hours
Drug clearance (CL)
Apparent total clearance, calculated as dose/AUC0-inf
Time frame: 0 to 24 hours
Apparent volume of distribution at the terminal phase (Vz)
Apparent volume of distribution at the terminal phase, calculated as CL/λz
Time frame: 0 to 24 hours

Metabolic Ratio (MR)
Metabolic ratio calculated as the molar concentration of sirolimus AUC0-inf to BIOtorcin AUC0-inf
Time frame: 0 to 24 hours
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 procedure
Major adverse event (MAE) rate
MAE is a composite of device or procedure related death within 30 days post index procedure, or major index limb amputation, or cd TLR at 1, 6 and 12 months post index procedure
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
cd TVR, defined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel, after documentation of recurrent clinical symptoms of the patient.
Time frame: 1, 6 and 12 months post index procedure
All-cause of death rate
Time frame: 1, 6 and 12 months post index procedure
Target limb major (above the ankle) and minor (below the ankle) amputation rate
Time frame: 1, 6 and 12 months post index procedure
Change in Rutherford Classification as compared to baseline
Time frame: 1, 6 and 12 months post index procedure
Change in Ankle Brachial Index (ABI) as compared to baseline
Time frame: 1, 6 and 12 months post index procedure
Change in Walking Impairment Questionnaire (WIQ) as compared to baseline
Time frame: 1, 6 and 12 months post index procedure
Target lesion Binary Restenosis rate
Defined as duplex ultrasound peak systolic velocity ratio (PSVR) \> 2.5 or angiographic assessment which suggests stenosis \> 50% by QVA
Time frame: 1, 6 and 12 months post index procedure
Target lesion Primary Patency rate
Defined as duplex ultrasound peak systolic velocity ratio (PSVR) ≤ 2.5 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
embolic event of the index limb rate
Time frame: during procedure
