WASHINGTON – Good pivotal-trial performance of a drug-coated balloon for treating superficial femoral and popliteal artery stenoses raised the prospect that it might soon be the third drug-coated balloon on the U.S. market, creating an opportunity for lower prices and competitive improvements for an increasingly used device.
“Having another drug-coated balloon would be useful for several reasons,” commented, during the Transcatheter Cardiovascular Therapeutics annual meeting. The competition should mean lower cost, and accumulating reports on performance might identify a specific drug-coated balloon as most effective. Drug-coated balloons for peripheral artery stenoses “have been introduced over the past 2 years, with a significant increase in use during that time. It’s still not a majority of patients, but it’s increasing,” said Dr. Gray, chief of the division of cardiovascular disease at Main Line Health and president of Main Line Health’s Lankenau Heart Institute in Wynnewood, Pa.
Thepivotal trial enrolled 300 patients at 43 centers in the United States and Europe. Patients had Rutherford 2, 3 or 4 disease, and averaged about 69 years old. More than 60% had class 3 disease and another 30% had class 2 disease.
The study’s primary safety endpoint was freedom from device- or procedure-related death to 30 days, and freedom from clinically drived target lesion revascularization at 12 months, a 92% rate in the 200 patients who had PTA with the Stellarex drug-coated balloon and 83% in the 100 controls who had PTA with an uncoated balloon. This statistically significant eight percentage point difference met the prespecified criteria for safety superiority.
The two drug-coated balloons already approved for U.S. use are theand the .
“All the drug-coated balloons have worked well. It’s pretty exciting to see them work. It will be interesting to compare them against each other. We need side-by-side comparisons,” commented, an interventional cardiologist in Houma, La. and a discussant for Dr. Lyden’s report.
The ILLUMENATE Pivotal trial was funded by Spectranetics, the company that is developing the Stellarex drug-coated balloon. Dr. Lyden has been a consultant to Spectranetics and to Biomet, Endologix, and TVA Medical. He received research support from Spectranetics and several other companies. Dr. Gray has been a consultant to Abbott Vascular, Boston Scientific, Cook, Medtronic, and Shockwave. He has received research support from Gore and Intact Vascular. Dr. Walker has been a consultant to Spectranetics as well as to Abbott Vascular, Bard, Boston Scientific, Cook, Gore, and Medtronic.
