Anti-CD14 Treatment and Mortality in Severe COVID-19: A Secondary Subgroup Analysis by Baseline Plasma Presepsin Levels in the I-SPY COVID Adaptive Platform Trial (ATS 2024) - "Our findings suggest that a baseline marker of CD14-pathway activity, presepsin, might identify severely ill patients with viral pneumonia more likely to respond to therapy blocking CD14-mediated inflammation. Although these analyses were based on small sample size, additional studies should be conducted to further test the hypothesis that presepsin-guided IC14 therapy is beneficial in severe viral pneumonia."

Phase 1b dose-escalation, safety, and pharmacokinetic study of IC14, a monoclonal antibody against CD14, for the treatment of amyotrophic lateral sclerosis. (PubMed, Medicine (Baltimore)) - P1b | "IC14 quickly and durably saturated its target in all patients. This study demonstrated safety and tolerability in patients with amyotrophic lateral sclerosis. Even though only a single cycle of treatment was given, there were promising beneficial trends in the neurofilament light chain, a disease biomarker. The emerging understanding of the role of systemic inflammation in neurodegenerative diseases, and the potential for IC14 to serve as a safe, potent, and broad-spectrum inhibitor of immune dysregulation merits further clinical study."
