Paclitaxel-coated Balloons in Femoral Indication to Defeat Restenosis
Summary
The aim of the study is correlating efficacy of the treatment to the proportion of paclitaxel-dose supplied by the catheter. Forty-five patients each will be treated by paclitaxel-coated or uncoated conventional balloon catheters in randomized order in 3 study centers. Main inclusion criteria are Rutherford class 2 - 5, ≥70% stenosis or occlusion in the superficial femoral or popliteal artery, main exclusion criteria are related to the use of paclitaxel and the need for follow-up examinations. Either clinical or angiographic follow-up examinations are planned 6, 12 and 24 months following the intervention. Primary endpoint is 6-month angiographic late lumen loss. Secondary endpoints are further angiographic and clinical efficacy and various safety criteria.
Description
Paclitaxel-coated balloons have been shown to reduce late lumen loss, restenosis rates and the need for repeat target lesion revascularization compared to conventional uncoated balloon catheters. The aim of the study is correlating efficacy of the treatment to the proportion of paclitaxel-dose supplied by the catheter. To this end paclitaxel loss of catheters in the introductory sheaths and residual paclitaxel on used balloons will be determined and correlated to individual data indicating inhibition of neointimal proliferation. According to the study protocol 45 patients each will be treated by paclitaxel-coated or uncoated conventional balloon catheters in randomized order in 3 study centers. Main inclusion criteria are Rutherford class 2 - 5, ≥70% stenosis or occlusion in the superficial femoral or popliteal artery, 3 to 30 cm of length; beyond common contraindications against PTA main exclusion criteria are related to the use of paclitaxel and the need for follow-up examinations. Patients will be blinded against treatment. Blinding of investigators after assignment of a patient to a treatment is not possible due to differences in the appearance of coated and uncoated catheters. Either clinical or angiographic follow-up examinations are planned 6, 12 and 24 months following the intervention. Primary endpoint is 6-month angiographic late lumen loss evaluated by a blinded independent core lab. Secondary endpoints are interventional success rate, restenosis rates, minimal lumen diameter, target lesion revascularization, change in Rutherford class, change in ankle-brachial-index, major amputations, a composite safety endpoint (defined as MAE =death of any cause, target limb amputation, clinically / DUS driven TLR) and all kinds of serious adverse events possibly related to the treatment.

Medical and Biotech [MESH] Definitions
Percutaneous Coronary Intervention
A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.
Angioplasty, Balloon
Use of a balloon catheter for dilatation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of balloon dilatation in coronary arteries, ANGIOPLASTY, TRANSLUMINAL, PERCUTANEOUS CORONARY is available.
Angioplasty, Transluminal, Percutaneous Coronary
Dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.
Radiography, Interventional
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
Angioplasty, Laser
A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
