Abstract 28: Patients Randomised to Glenzocimab Suffered Less Haemorrhagic Transformation at 24 Hours Compared to Placebo: AI-Imaging Sub-Analysis of the ACTIMIS Trial

Stroke Journal

Introduction:ACTIMIS (NCT03803007) was a randomized phase 1b/2a clinical trial evaluating glenzocimab, a monoclonal antibody fragment targeting platelet receptor glycoprotein VI in patients with acute ischemic stroke treated by thrombolysis. Day-7 imaging was available for 9 fewer placebo patients and 1 glenzocimab patient.

Abstract WMP64: Late Lesion Growth Following Endovascular Therapy: Is 24 Hours Too Early to Assess Acute Infarct Size Including the Effects of Secondary Injury?

Stroke Journal

These patients had an increased hemorrhagic transformation rate of 68% with only 1 in 3 patients having favorable clinical outcome. Additionally it can serve as an imaging biomarker for the development of adjunctive therapies to mitigate reperfusion injury.

Abstract 006: Glenzocimab Is Associated With Less Haemorrhagic Transformation Using Artificial Intelligence Imaging In Mechanical Thrombectomy Patients

Stroke: Vascular and Interventional Neurology

ACTIMIS (NCT03803007) was a randomized phase 1b/2a clinical trial evaluating glenzocimab, a monoclonal antibody fragment targeting platelet receptor glycoprotein VI, versus placebo in patients with acute ischemic stroke treated by thrombolysis alone or associated with mechanical thrombectomy (MT), both subgroups being well balanced.
