Sivelestat Sodium as an Adjunct to Endovascular Thrombectomy for Acute Anterior Circulation Large-Vessel Occlusion

Stroke remains a major global health burden, with acute ischemic stroke (AIS) accounting for more than 65% of all cases. Endovascular thrombectomy (EVT) has been established as a standard treatment for large vessel occlusion (LVO) stroke; however, "futile recanalization" remains common, with many patients failing to achieve favorable functional outcomes despite successful vessel reperfusion. Increasing evidence indicates that neutrophils and neutrophil extracellular traps (NETs) play important roles in post-reperfusion inflammation, thrombosis, and microcirculatory dysfunction, which may contribute to thrombolysis resistance and poor prognosis. Neutrophil elastase (NE), a key component associated with NETs, may further aggravate vascular injury and thrombus formation. Sivelestat Sodium is a selective NE inhibitor that has demonstrated anti-inflammatory and organ-protective effects in patients with acute respiratory distress syndrome and in experimental models of cerebral ischemia. It may help preserve blood-brain barrier integrity, reduce brain edema, and improve neurological outcomes. Based on these findings, this study is designed as a multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of sivelestat sodium as an adjunct to EVT in patients with acute anterior circulation large-vessel occlusive stroke within 24 hours of onset. The results of this study are expected to provide further clinical evidence for anti-inflammatory adjunctive treatment strategies aimed at reducing futile recanalization and improving functional outcomes in AIS.

Clonal Hematopoiesis and NETs Formation in Venous Thrombosis (CLODETTE)

Thrombo-embolic venous diseases are represented by deep venous thrombosis and/or pulmonary embolism. In some patients with repeated thrombosis or occurrence of thrombosis in unusual sites, the etiological workup remains negative, which represents a problem for the management of the anticoagulant treatments. Recently, two factors have been identified as important in the physiopathology of hemostasis and coagulation: the presence of clonal hematopoiesis of indetermined potential (CHIP) and the formation of neutrophil extracellular traps (NETs). In this study, these two factors will be studied in patients with repeated venous thrombosis or thrombosis occurring in unusual site.
