Summary. Background: Soluble thrombomodulin is a promising therapeutic natural anticoagulant that is comparable to antithrombin, tissue factor pathway inhibitor and activated protein C. Objectives: We conducted a multicenter, double‐blind, randomized, parallel‐group trial to compare the efficacy and safety of recombinant human soluble thrombomodulin (ART‐123) to those of low‐dose heparin for the treatment of disseminated intravascular coagulation (DIC) associated with hematologic malignancy or infection. Methods: DIC patients ( n = 234) were assigned to receive ART‐123 (0.06 mg kg −1 for 30 min, once daily) or heparin sodium (8 U kg −1 h −1 for 24 h) for 6 days, using a double‐dummy method. The primary efficacy endpoint was DIC resolution rate. The secondary endpoints included clinical course of bleeding symptoms and mortality rate at 28 days. Results: DIC was resolved in 66.1% of the ART‐123 group, as compared with 49.9% of the heparin group [difference 16.2%; 95% confidence interval (CI) 3.3–29.1]. Patients in the ART‐123 group also showed more marked improvement in clinical course of bleeding symptoms ( P = 0.0271). The incidence of bleeding‐related adverse events up to 7 days after the start of infusion was lower in the ART‐123 group than in the heparin group (43.1% vs. 56.5%, P = 0.0487). Conclusions: When compared with heparin therapy, ART‐123 therapy more significantly improves DIC and alleviates bleeding symptoms in DIC patients.
