RCT 54 hospitalized COVID-19 patients showing crizanlizumab treatment reduced soluble P-selectin levels, increased D-dimer levels, and decreased prothrombin fragment 1.2 compared to placebo. There were no significant differences in inflammatory markers, clinical outcomes, or adverse events between groups. The authors hypothesize that crizanlizumab may induce endogenous thrombolysis in COVID-19.

RCT 422 hospitalized COVID-19 patients showing no significant difference in mortality or organ support-free days with crizanlizumab, a P-selectin inhibitor. There was a trend towards increased mortality with crizanlizumab. The study was stopped early for futility.
