A head-to-head comparison of contemporary stents designed to show noninferiority for treatment of coronary artery disease (CAD) in patients with diabetes, ended up showing that one was superior to the primary endpoint of target lesion failure (TLF). In the superiority analysis, the 35% relative reduction in the risk of TLF at 1 year for the Cre8 EVO (Alvimedica) stent relative to the Resolute Onyx (Medtronic) device reached significance.

At 1 year, the rates of TLF were 7.2% and 10.5% for the Cre8 EVO and Resolute Onyx stents, respectively. On the basis of noninferiority, the 3.73% reduction in TLF at 1 year among those receiving the Cre8 EVO device provided a highly significant confirmation of noninferiority (P < .001) and triggered the preplanned superiority analysis.

According to the SUGAR (Second-Generation Drug-Eluting Stents in Diabetes) trial results presented at the Transcatheter Cardiovascular Therapeutics annual meeting, when the significant advantage on the TLF endpoint (= .03) was broken down into its components, the Cre8 EVO stent was linked to numerically lower rates of cardiac death (2.1% vs. 2.7%), target vessel MI (5.3% vs. 7.2%), and target lesion revascularization (2.4% vs. 3.9%).

The rationale for conducting a new trial limited to patients with diabetes was based on the greater risk in this population. The data data that indicate the risk of major adverse cardiac events are about two times higher 2 years after stent implantation in patients with diabetes relative to those without, even when contemporary drug-eluting stents are used.
