In the past, the search for neu- roprotective agents has been fraught with failure at the clinical trials stage due to numerous factors, including subject heterogeneity and improper therapeutic windows （Tymianski, 2017）. Moreover, it is becoming clearer that the complex and evolving pathobiology of stroke requires multimodal therapeutic approaches capable of modulating the numerous axes that contribute to ischemia/reperfusion damage, rather than targeting a single axis （Bernstock et al., 2018a）. With the success of recent endovascular thrombectomy （EVT） trials, it has been suggested that clinical trials of EVT with adjunct neuroprotection can overcome past difficulties and maximize the effect size by using imaging to reduce patient heterogeneity （i. e., selecting those with large vessel occlusions, small ischemic cores, and good collateral circulation）, restoring perfusion using better EVT devices, and enrolling patients in the correct therapeutic window （i.e., when they still have salvageable brain tissue） （Tymianski, 2017）. Considering the opportunity that this represents for new, better clinical trials of neuroprotective agents, the search is on for high-potential compounds that may be investigated in these future studies.展开更多
