BACKGROUND: The JET-RANGER study (NCT03206762) was a multicenter (11 US centers) randomized trial, core lab adjudicated, designed to demonstrate the superiority of Jetstream + Paclitaxel coated balloon (JET+PCB) versus angioplasty (PTA) + PCB in treating femoropopliteal (FP) arterial disease. The one-year primary endpoint of JET-RANGER has been recently published. The 2-year outcome data are presented in this report.
METHODS: There were 43 patients who completed the 1-year follow-up. Two were lost to follow-up and one died prior to the 2-year follow-up, resulting in 40 patients. Fifteen patients were randomized to PTA+PCB and 25 patients to JET +PCB. Kaplan Meier Survival analysis was performed to estimate the freedom from TLR. Bailout stenting was not considered a TLR in this analysis. Statistical significance was determined by a p-value < 0.05.
RESULTS: Freedom from TLR was similar between the 2 groups at 2 years. There was also no significant difference in the change of ABI between the PTA + PCB and JET + PCB from baseline at 6-months, (p-value = 0.7890), 1-year (p-value = 0.4070), and 2-year (p-value=0.7410). There was also no statistical difference between the JET + PCB and PTA + PCB arms for RCC improvement by one or more category, (p-value= 1.000). There were no minor or major amputations for either arm throughout the 2-year follow up. One JET + PCB patient died before the 2-year specified window.
CONCLUSION: JET + PCB had similar freedom from TLR and improvement in ABI and RCC at 2-year follow-up when compared to PTA + PCB with no difference in amputation or mortality between the 2 arms.
