Positive Results for Biotronik’s Pantera Lux Paclitaxel Releasing Balloon In Both Diabetic And Nondiabetic Subgroups

In short

Another press release from Biotronik following last week’s EuroPCR meeting in Paris talks of six-month results from the DELUX registry demonstrating excellent safety and efficacy results for the Pantera Lux Paclitaxel Releasing Balloon.

Background 

The Pantera Lux Paclitaxel Releasing Balloon is a novel treatment for restenotic coronary artery lesions after drug-eluting or bare metal stenting. The device is based on the highly deliverable Pantera semicompliant balloon, which is then coated with a matrix of proven antiproliferative paclitaxel and the biocompatible butyryl-tri-hexyl citrate (BTHC) excipient, which the company says enables optimal drug transfer to the target lesion tissue.

DELUX is a prospective, multicenter, international registry evaluating the Pantera Lux Paclitaxel Releasing Balloon in 1064 patients in a real-world setting. The primary endpoint was the 6-month cumulative MACE rate defined as a composite of all death, nonfatal myocardial infarction and clinically driven target vessel revascularization. Major secondary outcomes are cumulative MACE rates at 1 and 12 months.

The results of more than 1000 patients was presented by Ralph Toelg, MD, Segeberger Heart Center Clinic, Germany, and Thomas Schmitz, MD, Elisabeth Hospital, Germany during the EuroPCR congress. The registry enrolled a population of mostly in-stent restenotic patients (87.7%), yet still had a very low major adverse cardiac event (MACE) rate of 8.7% and a revascularisation rate of 3.2%. A further analysis of the diabetic subgroup of 363 patients showed similarly low revascularization rates of 4.4%.

Clinician comments

“Patients with a complex disease such as in-stent restenosis (ISR) or diabetes represent a cohort that continues to return to the catheter laboratory with repeat restenosis. Seeing these low event rates in such a high-risk patient group in the DELUX study suggests that the Pantera Lux can be a viable alternative in these types of cases,” remarked Dr. Toelg. “The data suggests that treatment with the Pantera Lux Paclitaxel Releasing Balloon is highly promising for DES restenosis and especially encouraging in patients with a previous bare metal stent (BMS), where we see a very low revascularization rate of 1.7%.”

Company comments

Alain Aimonetti, Vice President of Sales and Marketing, BIOTRONIK Vascular Intervention, commented, “BIOTRONIK is continuing to build clinical evidence for the Lux drug-eluting balloon program. The excellent results across different indications strengthen our firm belief that the Pantera Lux can be a valuable tool outside of in-stent restenosis (ISR) and allow us to continue our exploration into other therapy areas.”
