RANGER II SFA pivotal trial
Prospective, Multi-Center, Randomized Controlled Trial Ranger Drug-Coated Balloon vs. Uncoated Balloon (3:1). Follow-up through 5-Years.1
Ranger DCB delivers exceptional outcomes backed by durable, long-term results.
12-month primary patency rates K-M Estimate¹*
* Kaplan-Meier Estimate: Primary patency as determined by duplex ultrasound (DUS) Peak Systolic Velocity Ratio (PSVR) is ≤2.4 at the 12-month follow-up visit, in the absence of clinically driven TLR or bypass of the target lesion.
** At risk denotes the number of subjects entered in the calculation at the time interval.
*** Logrank p-value compares the entire K-M curves from time zero to full 1-year follow-up.
Ranger DCB demonstrated durability, with low reintervention rates through 4 years
K-M FREEDOM FROM CD-TLR
94.5% at 1-Year†
More than 9 in 10 patients did not need reintervention at 1 year
78.7% at 4-years‡
Nearly 8 in 10 patients did not need reintervention at 4 years
†Subjects at risk at day 365=255 subjects
‡Subjects at risk at day 1460=184 subjects
2-year subgroup analysis
Ranger DCB delivered exceptional outcomes in complex lesions at 2-Years.
Ranger DCB demonstrated low reintervention rates regardless of patient gender.
* PACSS Grade 3/4 Calcification
** Log-rank p-value compares the entire K-M curves from time point zero to day 760 (full 2-year follow-up window)
*** Log-rank p-value compares the entire K-M curves from time point zero to day 730 (full 2-year annual visit mark)

Primary safety endpoint: composite of freedom from device and procedure-related death through 30 days and freedom from major target limb amputation and CD-TLR through 1-Year post index-procedure.
Primary efficacy endpoint: primary patency at 1-Year defined as absence of clinically driven target lesion revascularization (CD-TLR) or binary restenosis determined as a peak systolic velocity ratio > 2.4 evaluated by duplex ultrasound core laboratory analysis.
CD-TLR: a reintervention performed for ≥ 50% diameter stenosis (confirmed by angiography) within ± 5 mm proximal and/or distal to the target lesion after documentation of recurrent clinical symptoms of PAD (increase of 1 Rutherford class or more) and/or drop of ABI (≥20% or >0.15 when compared to maximum early post-procedural level).
