InspireMD, Inc. announced that it completed enrollment of its ongoing C-Guardians U.S. Investigational Device Exemption (IDE) clinical trial, designed to support potential U.S. marketing approval of the CGuard Prime EPS stent system. The C-Guardians clinical trial is evaluating the safety and efficacy of the CGuard™ Carotid Stent System for the treatment of carotid artery stenosis. The study, which commenced enrollment in July 2021, enrolled 315 patients across 25 trial sites in the U.S. and Europe.

The trial includes both symptomatic and asymptomatic patients undergoing carotid artery stenting (CAS). The primary endpoint includes the composite of the following: incidence of the following major adverse events: death (all- cause mortality), all stroke, and myocardial infarction (DSMI) through 30-days post-index procedure, based on the Clinical Events Committee (CEC) adjudication or ipsilateral stroke from 31-365-day follow-up, based on CEC adjudication. The performance goal will be considered to have been met if the upper bound of the two-sided 95% confidence interval calculated from the observed primary endpoint rate is <11.6% and the p-value is <0.025.

The company anticipates results from the study in second half 2024.
