Study finds no significant difference in safety and efficacy outcomes of biodegradable versus durable polymer DES

The NEXT trial enrolled 3,241 patients from 98 centres in Japan from May to October 2011. The study population comprised 2,417 patients (1,204 patients with BP-BES and 1,213 with DP-EES) from 66 centres that agreed to participate in the extended study. 87.5% of patients achieved complete 10-year follow-up.

Following were the key findings:

• The cumulative 10-year incidence of death or MI was 34.0% in the BP-BES group and 33.1% in the DP-EES group (hazard ratio [HR] 1.04).
• TLR occurred in 15.9% of patients in the BP-BES group and 14.1% of the DP-EES group (HR 1.12).
• In a landmark analysis at one year, the cumulative incidences of death or MI and TLR were not significantly different between the two groups.

"BP-BES's safety and efficacy outcomes were not significantly different from those for DP-EES at one year and up to 10 years after stent implantation," the researchers concluded.
