Local Paclitaxel Delivery for SFA Disease (IRRITAX)

April 1, 2026 updated by: University of Oklahoma

Treatment of Superficial Femoral Artery Atherosclerotic Disease With Local Delivery of Paclitaxel Using an Irrigating Catheter: a Single-center Pilot Study

To see if restenosis rates of superficial femoral artery atherosclerosis with percutaneous techniques can be improved using paclitaxel.

Conditions

Intervention / Treatment

Detailed Description

Treatment of superficial femoral artery atherosclerosis with percutaneous techniques is hindered by high restenosis rates. Paclitaxel inhibits restenosis in coronary arteries, and a few studies suggest it may be effective in reducing restenosis rates in peripheral arteries. The investigators hypothesize that delivering paclitaxel through an irrigating catheter will be superior in preventing restenosis.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Paclitaxel
Participants will receive Paclitaxel.
Drug: Paclitaxel
Paclitaxel will be administered intra-arterially through an irrigating catheter to treat a diseased segment of superficial femoral artery. Dosing will be based on ther lesion surface area, and will be calculated using the following formula: dose= 22/7 X diameter (mm) X length (mm) X 3 micrograms/mm^3
