Trial Outcomes & Findings for Moxy Drug Coated Balloon vs. Standard Balloon Angioplasty for the Treatment of Femoropopliteal Arteries (NCT NCT01412541)

Moxy Drug Coated Balloon vs. Standard Balloon Angioplasty for the Treatment of Femoropopliteal Arteries

Composite of freedom from all-cause peri-operative (≤30 day) death and freedom at 1 year from the following: index limb amputation (above or below the ankle), index limb re-intervention, and index-limb-related death.

Primary Patency is defined as the absence of target lesion restenosis (defined by DUS peak systolic velocity ratio (PSVR) ≥2.5) and freedom from target lesion revascularization (TLR).

Device Success was defined as the achievement of successful delivery and deployment of the study device(s) as intended at the intended target lesion, without balloon rupture or inflation/deflation abnormalities and a successful withdrawal of the study system.

Technical Success is defined as successful access and deployment of the device and visual estimate of ≤30% diameter residual stenosis during the index procedure without deployment of a bailout stent. Procedural Success is defined as attainment of ≤30% residual stenosis in the treatment area by independent core lab analysis without serious adverse events during the index procedure.

Primary Patency is defined as the absence of target lesion restenosis (defined by core lab adjudication or strict application of PSVR thresholds) and freedom from target lesion revascularization (TLR).

Percentage of subjects with Alternative Primary Patency based on alternative definitions of duplex ultrasound (DUS) peak systolic velocity ratio (PSVR) \<2.0 and \<3.0 at 6, 12, and 24 months post index procedure. DUS PSVR was calculated by dividing the maximum peak systolic velocity (PSV) from the stenosis by the PSV from the nearest segment of normal artery above the site of increase.

DUS Clinical Patency defined as DUS PSVR \<2.5 without prior clinically driven target lesion revascularization (TLR).

The endpoint summarizes the change in index-limb Rutherford Classification of participants from baseline through 24 months. Data is presented as shift from baseline Rutherford Classification data using the following categories: 1) Improvement, 2) Same, and 3) Worsened.

Mean change from baseline values. The Ankle Brachial Index (ABI) is defined as a ratio of ankle to brachial (upper arm) artery systolic blood pressure and aims at determining how well the blood is flowing in the legs.

The data bellow is presented as a Mean change in scores for the Six Minute Walk Test scores at 6, 12, and 24 months compared to baseline.

Mean change in EuroQol (EQ-5D) scores at 6, 12, and 24 months compared to baseline. The EurolQol-5D system rates quality of life using five dimensions including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels of ratings, that is, no problems, slight problems, moderate problems, severe problems and extreme problems that can be selected. A visual scale allows participants to report their own perception of their health status. The overall scores range from 0 (worst) to 100 (best). Please note that the data in the table below represent the mean changes in overall scores for each group compared to their baseline data.

Mean change from Baseline on the Short Form (SF-36 v2) Quality of Life Questionnaire at 6, 12, and 24 months. The SF-36 v2 United States (US) is a brief measure of general health status. The physical health measure of the test comprises four scales, that is, physical functioning (10 items), role-physical (4 items), bodily pain (2 items), and general health (5 items). The scores range between 0 and 100 (with higher scores indicating better health). In the results presented below, a positive Mean represents an increase in the average health score while a negative Mean represents a decrease in the same mean score compared to baseline measure.

Mean change in quality of life (mental component) on Short-form 36 (SF-36 v2) from baseline at 6, 12, and 24 months. The SF-36 v2 United States (US) is a brief measure of general health status. The mental health measure comprises four scales, that is, vitality (4 items), social functioning (2 items), role-emotional (3 items), and mental health (5 items). The scores range from 0 to 100 (with higher scores indicating better health). In the results presented below, a positive Mean represents an increase in the average health score while a negative Mean represents a decrease in the same mean score compared to baseline measure.

Number of subjects with Freedom from all-cause death, index limb amputation above the ankle and Target Vessel Revascularization (TVR) (VIVA Safety Endpoint)

Amputation defined as above the ankle free survival (AFS). PPI = Post index procedure.

The WIQ assesses 3 categories of activities that include 1) walking distance, 2) stair-climbing, and 3) walking speed. Each question requires participants to rate their degree of difficulty with the activity on a scale of 0 (unable) to 4 (no problem). Final scores range from 0% to 100%, with lower percentages indicating higher levels of difficulties with activities.The results below represent the mean differences in total Walking Impairment Questionnaire (WIQ) scores at 6, 12, and 24 months, compared to baseline assessment scores.
