About SHIELD II

The SHIELD II Phase 3 trial was a prospective, multinational, randomized, double-blind study that successfully met its primary and all key secondary efficacy endpoints. The trial demonstrated that D-PLEX₁₀₀, when administered alongside standard of care, achieved a 38% reduction (p<0.005) in the combined endpoint of surgical site infections, reinterventions, or mortality compared to standard of care alone. Additionally, the trial showed a 58% reduction (p<0.005) in the rate of surgical site infections in the D-PLEX₁₀₀ treatment arm.
