FDA Alert on Drug-Coated Balloons and Stents in Femoropopliteal Artery Disease

The US Food and Drug Administration (FDA) has issued an alert on the potential long-term risk of paclitaxel-coated balloons and paclitaxel-eluting stents in patients with femoropopliteal artery disease.

In its letter, the FDA warns about the increased mortality risk at 2 years observed in a large meta-analysis of patients with peripheral vascular disease treated with paclitaxel-coated devices.

The next reviews will focus on long-term results supporting the initial approval of these devices.

 

The aforementioned meta-analysis, published in the Journal of the American Heart Association in December 2018 by Dr. Katsanos et al., pointed to a 68% relative risk increase in all-cause death at 2 years and a 93% relative risk increase by 5 years in patients who received paclitaxel-eluting devices.

 

One week after the publication, two ongoing trials were halted.

The answer is not definitive: we ignore the causes for these deaths and the paclitaxel dose eluted by these devices. If there indeed is an increase in mortality caused by paclitaxel, its dosing may be crucial. This varies greatly among devices and depending on their number (receiving three drug-eluting balloons offers different results than only one, and the same goes for stents).

 

Our conclusion may be that we can continue using these devices (which have proven very effective), but keeping in mind these recent data so as to perfect our benefit/risk assessment.
