Plain English Summary

Background and study aims
Atherosclerosis is a condition where the blood vessels (arteries) become narrow. Atherosclerosis affecting the superficial femoral artery (a large artery in the thigh) may cause pain and reduced blood flow to the leg, leading to serious complications such as tissue loss, amputation and even death. Surgery can be used to restore the blood flow, relieve symptoms and prevent or delay these complications. Percutaneous transluminal angioplasty (PTA) is a procedure to open up the blocked artery using a small plastic tube (catheter) with a balloon and a small mesh tube (stent) at the end. When the tube is in place, it inflates to open the artery. The stent expands so that it acts as a scaffold and holds open the artery. However, the artery becomes narrow again (restenosis) in 45% of patients at 2 years follow-up. Using balloons covered in paclitaxel/shellac may prevent the artery walls from thickening. The aim of this study is to demonstrate whether there is a beneficial effect of using paclitaxel/shellac covered balloons over standard PTA on the occurrence of restenosis.

Who can participate?
Patients over 18 years old with atherosclerosis of the superficial femoral artery

What does the study involve?
Participants are randomly allocated to one of two groups. The intervention group undergo PTA using the paclitaxel/shellac covered balloons followed by placement of a stent. The control group undergo standard PTA followed by placement of a stent. Restenosis rates are compared at 1, 6, 12 and 24 months follow-up and during unplanned visits.

What are the possible benefits and risks of participating?
A possible benefit is reduction of restenosis. The risks are the same as standard PTA and stenting. The use of similar balloons is safe in coronary (heart) artery interventions.

Where is the study run from?
St Antonius Hospital Nieuwegein (Netherlands)

When is the study starting and how long is it expected to run for?
June 2012 to January 2014

Scientific titleRAndomized trial of Legflow® PaclItaxel Eluting Balloon (LPEB) with stentplacement vs. stanDard percutaneous transluminal angioplasty (PTA) with stentplacement for the treatment of intermediate (>5 cm and < 15 cm) and long (>15 cm) lesions of the superficial femoral artery (SFA): the RAPID trial
Study acronymRAPID
Study hypothesisTreatment with the Legflow® Paclitaxel eluting balloon in combination with Nitinol stents will lead to significantly lower restenosis rates when compared to conventional uncoated balloon angioplasty combined with the same Nitinol stents in treatment of intermediate (>5 cm and < 15 cm) and long-segment (> 15 cm) SFA lesions.
Ethics approval(s)Ethics Committee of the St. Antonius Hospital Nieuwegein, 27/04/2012, ref: R-12.009
ConditionAtherosclerotic lesions of the superficial femoral artery
InterventionThe intervention group will undergo endovascular dilatation of intermediate and long lesions of the SFA with the LegFlow® Paclitaxel eluting balloon followed by placement of a nitinol selfexpandable stent (Supera®, IDEV inc., Webster TX).

The control group will undergo endovascular dilatation of the SFA with standard PTA followed by placement of the same Supera® stent.
Intervention typeProcedure/Surgery
Primary outcome measureAbsence of binary restenosis, measured with duplex ultrasound (DUS), and if indicated with digital subtraction angiography (DSA), at 1, 6, 12 and 24 months follow-up and unplanned visits
Secondary outcome measures1. Immediate outcome: Ankle Brachial Index (ABI), toe pressures, angiography
2. Clinical outcome: periferal artery questionnaire
3. Hemodynamic outcome: ankle-brachial index (ABI), Toe pressures
4. Reocclusion rate: DUS, DSA
5. Target-lesion revascularization: Follow-up
6. Target-extremity revascularization: Follow-up
7. Mortality rate: Follow-up
8. Amputation rate : Follow-up
9. Rate of device-specific problems: Follow-up with DUS, DSA when indicated

All endpoints will be scored at regular follow-up and during unplanned visits.
