Efficacy and Safety of Nerinetide in Acute Ischemic Stroke Patients: A Systematic Review, Meta-Analysis and Meta Regression.
(PubMed, Brain Behav)
- "Nerinetide may modestly reduce mortality in AIS without increasing adverse events but does not significantly improve the functional outcomes. The benefits may be greater in patients who do not receive thrombolysis. Further large-scale trials are warranted to clarify the optimal use and interactions with reperfusion therapies."

Development of a novel cyclotide to target neuronal excitotoxicity
(Neuroscience 2025)
- "This signalling cascade can be blocked using a therapeutic peptide known as Nerinetide or NR2b9c...Further, administration of c5R-NR2B9c in a mouse model of epilepsy resulted in increased survival and reduced seizure severity after seizure induction. Overall, we show that modifying cyclotides can enhance delivery of therapeutic peptides into neuronal cells, which can be utilized to protect neurons from excitotoxicity."

Neuroprotective Agents With Reperfusion Therapies in Ischemic Stroke: Evidence From Recent Randomized Trials.
(PubMed, Cureus)
- "Interventions included nerinetide, edaravone (and its derivatives), nelonemdaz, cerebrolysin, minocycline, glyceryl trinitrate, and normobaric hyperoxia. Quality assessment using the Cochrane Risk of Bias (RoB) 2.0 tool revealed low to moderate risk of bias across most studies. Although the evidence remains heterogeneous, this review highlights the potential role of neuroprotective agents as adjuncts to reperfusion therapy and identifies promising directions for future clinical trials."

Incidence, Associations, and Mechanisms of Unexplained Early Neurologic Deterioration After Thrombectomy in Stroke Patients.
(PubMed, Neurology)
- "UnEND occurred in approximately 10% of large vessel occlusion thrombectomy patients and was associated with older age, longer onset-to-reperfusion time, and anesthesia use. Patients who experienced IEBP, that is, 24-hour infarct volume extension beyond the initial hypoperfused tissue, were 7 times more likely to develop unEND."

Uncoupling toxic NO signaling: Progress, challenges, and therapeutic promise of disrupting the PSD-95/nNOS protein-protein interaction.
(PubMed, Eur J Med Chem)
- "Over the past two decades, cell-penetrant peptides such as nerinetide (Tat-NR2B9c) have validated the target from rodent stroke models to phase-III clinical trials, while bivalent constructs achieve low-nanomolar affinity and extended brain exposure. Parallel medicinal-chemistry campaigns have delivered multiple small-molecule scaffolds (IC87201, ZL006, SCR-4026, PCC-0105002) that cross the blood-brain barrier, disrupt the complex at low-micromolar concentrations, and demonstrate efficacy in ischemic stroke, neuropathic pain, and neuropsychiatric paradigms without the liabilities of NMDAR antagonists...Structural elucidation of ligand-bound complexes, covalent and bivalent chemistries, and AI-guided design promise to surmount these hurdles. Collectively, the evidence positions PSD-95/nNOS disruption as a versatile, clinically achievable approach for mitigating excitotoxic and nociceptive pathology and sets the stage for first-in-class therapies that uncouple toxic NO..."

Association between Time and Severe Hypoperfusion with Risk of Hemorrhagic Transformation in Stroke Patients.
(PubMed, Int J Stroke)
- "Both severe hypoperfusion and time affect the risk of hemorrhagic transformation. However, the interaction between these two variables was not statistically significant, indicating that their effects on hemorrhagic transformation risk are not dependent on each other. Analyzing these variables may help identify patients with a leaky, severely compromised blood-brain barrier in the ischemic core-a "leaky core."."

INCIDENCE, ASSOCIATED VARIABLES, AND UNDERLYING MECHANISMS OF UNEXPLAINED EARLY NEUROLOGICAL DETERIORATION IN THROMBECTOMY STROKE PATIENTS
(ESOC 2025)
- " Data are from the ESCAPE-NA1 trial, a randomized trial evaluating nerinetide in thrombectomy stroke patients... Unexplained END occurred in 10% of stroke thrombectomy patients and was associated with older age, longer onset-to-reperfusion time, and anesthesia use. unEND may be driven by the transformation of benign oligemia (asymptomatic tissue) to ischemic penumbra/infarction."

NEUROFILAMENT LIGHT AS A MARKER OF NEUROAXONAL INJURY IN THE ESCAPE-NEXT TRIAL
(ESOC 2025)
- " We conducted a biomarker sub-study of the ESCAPE-NEXT trial and included 193 participants (109 treated with Nerinetide) at 19 sites... Plasma NfL levels correlated with infarct volume, outperformed infarct volume in predicting functional outcomes, and captured treatment effects. These findings support the inclusion of blood NfL as an exploratory endpoint in acute stroke trials."

Impact of Brain Frailty on Clinical Presentation and Neurologic Recovery in Acute Ischemic Stroke Patients Undergoing Thrombectomy.
(PubMed, Neurology)
- "This study highlights the association of brain frailty with the clinical presentation and recovery trajectory of patients with AIS undergoing EVT. Specifically, cortical atrophy was independently associated with baseline stroke severity, and the total burden of brain frailty was independently associated with NIHSS recovery trajectories. The results emphasize the importance of considering brain frailty in acute stroke management and prognostication."

Safety and efficacy of nerinetide in patients with acute ischaemic stroke enrolled in the early window: a post-hoc meta-analysis of individual patient data from three randomised trials.
(PubMed, Lancet Neurol)
- "Nerinetide showed a clinically significant benefit over several outcome measures, including the modified Rankin Scale score, the incidence of stroke worsening, and infarction volumes. Neuroprotection with nerinetide might, therefore, be indicated for patients within 3 h of stroke onset and who are selected for reperfusion. These inclusion criteria should be tested in a future trial."
