About
Efficacy and safety of Neu2000, a multi-target drug designed to prevent both NMDA receptor-mediated excitotoxicity and free radical toxicity, will be investigated in acute ischemic stroke patients receiving endovascular treatment to remove clot within 12 hours following stroke onset. Neu2000KWL will be administered before endovascular treatment.
Full description
Neu2000 was designed as a multi-target neuroprotectant preventing both the NMDA receptor, a Ca2+ -permeable glutamate receptor, and free radicals, two major routes of brain cell death in stroke. Neu2000 is a moderate NR2B-selective NMDA receptor antagonist and spin trapping molecule (=free radical scavenger or antioxidant). Therapeutic potential of Neu2000 has been well demonstrated in four animal models of stroke with better efficacy and therapeutic time windows than either NMDA receptor antagonist or anti-oxidant advanced to clinical trials. In human phase I studies of 165 healthy subjects conducted in the United States and China, Neu2000KWL showed promising safety profiles without any serious adverse events up to a single intravenous infusion of 6000 mg that is far beyond the therapeutic target dose determined in animal models of transient ischemic stroke. Very recently, acute endovascular recanalization therapy has been introduced as the new standard care of care in acute ischemic stroke. The present study is aimed to examine efficacy and safety of Neu2000KWL in acute ischemic stroke patients receiving endovascular thrombectomy within 12 hours of stroke onset. This is a randomized trial, with placebo comparison, of comparing functional outcome at week 12 after 10 times of administration for five days.
