Nerinetide is a neuroprotective eicosapeptide designed to reduce ischemic brain injury by disrupting the interaction between N-methyl-D-aspartate (NMDA) receptors and downstream excitotoxic signaling. It was tested in two major clinical trials for acute ischemic stroke: • ESCAPE-NEXT Trial: Assessed Nerinetide in patients undergoing endovascular thrombectomy (EVT) without prior thrombolysis, finding no significant improvement in functional independence at 90 days. • FRONTIER Trial: Evaluated prehospital Nerinetide administration within 3 hours of stroke onset, showing no overall benefit but potential efficacy in ischemic stroke patients receiving reperfusion therapy. Although Nerinetide was safe, its clinical benefit remains uncertain, with timing and patient selection emerging as key factors for its potential role in stroke treatment. Further studies are needed to refine its use in combination with reperfusion therapies.

Acute hearing loss can be an early sign of posterior circulation stroke, particularly in anterior inferior cerebellar artery (AICA) infarctions. However, hearing assessments are often overlooked due to the NIH Stroke Scale's focus on anterior strokes. Real-world data showed missed diagnoses of vascular events when hearing loss was not evaluated. Integrating portable audiometry into stroke protocols could improve diagnostic accuracy and lead to timely interventions.

Three recent trials investigated the effectiveness of endovascular treatment (EVT) in ischemic stroke. The OPENS-2 trial (Lancet 2025) found that normobaric hyperoxia combined with EVT improved 90-day functional outcomes for large-vessel occlusion stroke without increasing adverse events. The DISTAL trial (NEJM 2025) reported no significant benefit of EVT over medical therapy for medium/distal vessel occlusions and noted a higher risk of hemorrhage. Similarly, the ESCAPE-MeVO trial (NEJM 2025) found no improvement with EVT in medium-vessel occlusion stroke, alongside increased mortality and intracranial hemorrhage. Collectively, these findings suggest that EVT's benefits depend on vessel size and may be enhanced with adjunctive treatments like hyperoxia in specific cases.
