Panel Votes Down BD’s Lutonix Balloon PTA Catheter
FDA’s Circulatory System Devices Panel has voted not to recommend approval of BD’s Lutonix drug-coated balloon PTA (percutaneous transluminal angioplasty) catheter for treating below-the-knee lesions in patients with critical limb ischemia. Panel members voted 15 to 2 in support of the device’s safety, 2 to 15 against its effectiveness, and 3 to 14 against its benefits outweighing the risks.
An FDA briefing document released in advance of the meeting (see earlier story) said that limitations associated with the primary and supplementary data in the PMA made it challenging to draw conclusions regarding the safety and effectiveness of the device. The document said that to date FDA has not noted any safety concerns associated with using the catheter that would be expected to exceed those of current standard of care with non-drug-containing devices.
“A modest benefit in regard to the primary effectiveness endpoint compared to PTA can be seen at six months but a reversed outcome was noted at 12 months and beyond,” the document said…. “Overall, the study was terminated early and did not meet the pre-specified hypothesis test success criteria. It remains unclear whether the effectiveness differences at six months are clinically meaningful and that the benefits of the paclitaxel-coated Lutonix 014 DCBN outweigh the risks compared to treatment with an uncoated balloon for treatment of atherosclerotic lesions below the knee.”
FDA says that if approved, the Lutonix device would be the first device other than PTA and atherectomy to be indicated for treating below-the-knee critical limb ischemia in the U.S.
