Brain-derived tau for monitoring brain injury in acute ischemic stroke

Article

A specific and accurate blood test for acute brain injury could help monitor infarct growth in ischemic stroke and serve as a surrogate end point in clinical trials. Using a single-molecule detection assay, we assessed plasma brain-derived tau (BD-tau), a marker selectively quantifying tau protein from the central nervous system, in a prospective cohort of 502 patients with acute ischemic stroke with serial blood sampling from admission to day 7. Higher BD-tau concentrations at admission were associated with more extensive early brain injury on computed tomography and predicted larger final infarct volumes. BD-tau increases from admission to day 2 were related to infarct growth. BD-tau concentrations rose until day 7 and were higher in patients with secondary events, including recurrent stroke. After thrombectomy, the rise of BD-tau was smaller in patients with complete versus incomplete recanalization. BD-tau outperformed other blood markers and imaging metrics in predicting 90-day functional outcome across infarct size strata and time points. In an independent multicenter prospective cohort ( N = 519), BD-tau showed higher performance than magnetic resonance imaging–derived final infarct volume in predicting functional outcomes at 3, 12, and 36 months. In the biomarker substudy of a phase 3 trial assessing nerinetide in patients with ischemic stroke ( N = 193), BD-tau showed predictive performance comparable to the other cohorts, mediated the relationship between recanalization and functional outcome, and showed a 49% smaller increase in the nerinetide group versus placebo. Overall, plasma BD-tau tracked ischemic brain injury over time, outperformed other biomarkers in predicting functional outcomes, and identified possible treatment responses.

Association between time and severe hypoperfusion with risk of hemorrhagic transformation in stroke patients

Article

Author: Jadhav, Ashutosh P ; Burns, Paul ; Hill, Michael D ; Pensato, Umberto ; Puri, Ajit S ; Demchuk, Andrew M ; Ospel, Johanna M ; Rha, Joung-Ho ; Kashani, Nima ; Rex, Nathaniel ; Yu, Amy YX ; Goyal, Mayank

Introduction::

Perfusion imaging studies show a substantially increased risk of hemorrhagic transformation (HT) in severely hypoperfused tissue. Preclinical evidence indicates that ischemic damage is influenced not only by the degree of hypoperfusion but also by the duration of exposure to that hypoperfused state. We aim to investigate the association of time and severe hypoperfusion with parenchymal hematoma (PH) in ischemic stroke and explore whether there is a combined effect of the two variables on PH.

Methods::

Data are from the ESCAPE-NA1 trial, which evaluated the effect of nerinetide in large vessel occlusion patients treated with thrombectomy. This study included patients with some degree of recanalization (expanded Thrombolysis in Cerebral Infarct [eTICI] > 0) and available baseline CT perfusion. Severe hypoperfusion was defined as at least 1 mL volume of relative cerebral blood flow (rCBF) <20%. We assess 24-h imaging for the presence of PH, according to Heidelberg bleeding criteria. Univariable and multivariable logistic regression analyses, including interaction terms, were used to assess the effect of time and severe hypoperfusion on outcomes.

Results::

Out of 1105 patients from ESCAPE-NA1, 396 (35.8%) were included. The median age was 70 years (IQR = 59.8–79.2), 202 (51%) were females, and 50 (12.6%) experienced PH. Onset-to-imaging time (adjusted OR 1.04 [95% CI = 1.01–1.06] per 15-min increase) and the presence of severe hypoperfusion (adjusted OR 2.87 [95% CI = 1.47–5.63]) were the only variables associated with PH in multivariable analysis. No significant interaction effect of time and severe hypoperfusion on PH was found. The presence of severe hypoperfusion had a negative predictive value of 98% and a positive predictive value of 39.4% for predicting PH in patients presenting within 3 h and after 6 h from symptom onset, respectively.

Conclusion::

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.”

Therapeutic potential of nerinetide in acute ischemic stroke: a comprehensive systematic review and meta-analysis

Article

Author: Noor Islam, Laiba ; Binte Nasir, Rehma ; Humayun Hilaly, Khadija ; Sawai Suthar, Sajan ; Zameer, Rimsha ; Kumar, Vikash ; Kumari, Shilpa ; Mohsin Zahoor, Muhammad ; Kumar, Ayush ; Geeta, Fnu ; Khan Ghori, Taimour ; Bai, Anusha ; Simran, Fnu

Background and Objectives::

Acute ischemic stroke (AIS) is a leading cause of disability and death worldwide. Nerinetide, a neuroprotective peptide, has shown potential in limiting neuronal damage when administered early after stroke onset. This study aimed to evaluate the efficacy and safety of nerinetide compared with placebo in patients with AIS.

Methods::

A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted in accordance with PRISMA and AMSTAR 2 guidelines. Electronic databases, including PubMed, MEDLINE, Cochrane Library, ScienceDirect, and ClinicalTrials.gov, were searched up to February 2025. The primary outcome assessed was mortality, while secondary outcomes included functional recovery (modified Rankin Scale, Barthel Index), infarct volume, and adverse events.

Results::

Three RCTs encompassing 2462 patients met the inclusion criteria. Nerinetide treatment demonstrated a modest yet statistically significant reduction in mortality risk (risk ratio = 0.86; P = 0.05). However, no significant improvement was observed in functional recovery or infarct size. The frequency of adverse events was comparable between the nerinetide and placebo groups, with minimal variability.

Conclusion::

Nerinetide may slightly reduce mortality in AIS, particularly among patients not treated with alteplase. Although functional outcomes did not significantly improve, its favorable safety profile and potential neuroprotective effect support further investigation in larger clinical trials.

NoNO Inc. Announces First Patient Dosed with NoNO-42 in a First in Humans Phase 1 Study

TORONTO, Nov 22, 2022 – NoNO Inc. is pleased to announce the dosing of the first participant in its Phase 1 clinical trial evaluating NoNO-42. NoNO-42 is the next generation drug developed in NoNO’s PSD-95 inhibitor platform. It is intended for the treatment of all people experiencing an acute ischemic stroke. The first in human study with NoNO-42 will evaluate the safety, tolerability and pharmacokinetics of single ascending doses of NoNO-42 in consecutive cohorts of healthy volunteers. NoNO-42 builds on NoNO’s ground-breaking results for its first-generation PSD-95 inhibitor, nerinetide. In the Phase 3 ESCAPE-NA1 trial, participants who were treated with nerinetide but not with thrombolytics (“clot-busters”) exhibited improved functional independence, reduced stroke mortality, and reduced brain damage on medical imaging. ESCAPE-NA1 was conducted in stroke in patients who were selected to undergo endovascular thrombectomy, a treatment in which the blood clots causing the stroke are removed in order to restore blood flow to the brain. The study provided evidence that such patients may benefit from nerinetide if they are not previously treated with thrombolytics. However, in patients who had already received thrombolytic treatment nullified the efficacy of nerinetide. The results in the no-thrombolytic arm are currently under confirmatory testing in the ongoing Phase 3 ESCAPE-NEXT trial. NoNO-42 was developed to be administered with or without thrombolytic agents. It extends the potential benefits of PSD-95 inhibition to those patients who, in ESCAPE-NA1 were previously treated with thrombolytics and therefore could not benefit from nerinetide. “The Phase 1 trial of NoNO-42 is a key milestone in extending the benefits of PSD-95 inhibition all acute ischemic stroke patients. Given NoNO-42’s similarities to nerinetide in all material clinical aspects other than its expected efficacy with or without thrombolytics, success with current pivotal trials with nerinetide will de-risk NoNO-42 development substantially” said Dr. Michael Tymianski, President, CEO and founder of NoNO Inc. “The stroke neurology community is extremely excited about the prospects of both nerinetide and NoNO-42, and the academic community is eager to follow-up ESCAPE-NEXT with clinical trials to investigate the efficacy of NoNO-42 in stroke patients” said Dr. Michael Hill, MD, Global Principal Investigator and Professor of Neurology at the Cumming School of Medicine, University of Calgary. NoNO Inc. is a clinical stage, stroke-focused Ontario biotechnology company dedicated to offering people who experience stroke opportunities for a better life. NoNO’s therapeutic strategy is to inhibit key protein-protein interactions of PSD-95 that are involved selectively in cellular signals that cause stroke damage, but without interfering with normal cell functions. Our PSD-95 inhibitor platform consists of: Nerinetide, NoNO’s lead compound for people experiencing an ischemic stroke, currently completing its second global Phase 3 trail in people not previously treated with a clot dissolving drug. NoNO-42, in Phase 1 for use alongside clot dissolving drugs for all people experiencing ischemic stroke. NoNO-SC, administered subcutaneously to enable the treatment of people experiencing stroke outside of medical setting by anyone – anywhere. For more information, please visit www.nonoinc.ca.

NoNO Inc. Announces the Start of the Global Phase 3 ESCAPE-NEXT Trial of the Peptide Nerinetide in Acute Ischemic Stroke Excluding Thrombolysis

TORONTO, Dec 6, 2020 – NoNO Inc. is pleased to announce the enrollment of the first patient in the ESCAPE-NEXT trial, NoNO’s second global phase 3 trial of its lead peptide, Nerinetide. ESCAPE-NEXT is a multicentre, randomized, double-blinded, placebo-controlled, parallel group, single-dose design to determine the efficacy and safety of nerinetide in participants with acute ischemic stroke undergoing endovascular thrombectomy (EVT). ESCAPE-NEXT is informed by the ESCAPE-NA1 trial which suggested that treatment with nerinetide may improve functional independence, reduce stroke mortality, and reduce brain damage due to stroke in patients who undergo EVT without the prior administration of thrombolytic (“clot busting”) agents. ESCAPE-NA1 results were presented at the 2020 International Stroke Conference in February. “Our prior trial showed us which stroke patients may benefit from nerinetide. ESCAPE-NEXT is a further pivotal study, focused on those patients, and is intended to confirm the promising findings of clinical benefits suggested by ESCAPE-NA1. ESCAPE-NEXT has a substantially similar design, but focuses on those patients who may experience the greatest benefit from nerinetide” said Dr. Michael Tymianski, President, CEO and founder of NoNO Inc. “We are exploring a novel mechanism of action for a new drug in a very common, but devasting disease. A new drug for acute ischemic stroke has the potential to further transform stroke therapeutics,” said Dr. Michael Hill, MD, Global Principal Investigator and Professor of Neurology at the Cumming School of Medicine, University of Calgary. ESCAPE-NEXT is designed to evaluate the clinical benefits of nerinetide in acute stroke patients who are selected for endovascular revascularization without prior treatment with intravenous thrombolytic therapy. The trial will enroll adult participants in the USA, Canada, Europe and Australia. It has an initial enrollment target of 680 participants, with an option to increase the sample to 1020 following an interim analysis. Pivotal outcomes will be evaluated at 90 days with a further analysis at one year after the stroke.

Press Release - NoNO Inc. | Change Everything

Toronto, Canada, April 7, 2021, 2PM ET – NoNO Inc., an Ontario biotechnology company developing innovative neurotherapeutics for acute stroke and other central nervous system disorders, announced today the publication of prototypes for next generation protease-resistant PSD-95 inhibitors. Published in the journal Science Translational Medicine, the article entitled “Plasmin-resistant PSD-95 inhibitors resolve effect-modifying drug-drug interactions between alteplase and nerinetide in acute stroke” demonstrates the potential of novel next-generation protease-resistant compounds for the treatment of acute ischemic strokes. Such compounds may be practically integrated into current stroke care workflows without the need to modify existing medical practice. These next generation compounds are expected to extend the therapeutic utility of PSD-95 inhibition to all eligible stroke patients, including those that are treated with drugs such as alteplase. The next generation compounds build on nerinetide, NoNO Inc.’s clinical stage lead PSD-95 inhibitor compound. Nerinetide was recently tested in the Phase 3 ESCAPE-NA1 study which provided promising results for the clinical safety and efficacy of nerinetide in acute ischemic stroke, as published in the journal The Lancet. ESCAPE-NA1 showed that nerinetide is promising in stroke patients who do not receive prior treatment with the thrombolytic agent, alteplase, and this is currently being evaluated further in the ongoing global Phase 3 ESCAPE-NEXT study. If ESCAPE-NEXT is successful, both studies will provide support for PSD-95 inhibition as a platform therapy for stroke and related neurological disorders. NoNO Inc. CEO Dr. Michael Tymianski commented that, “Nerinetide and next generation PSD-95 inhibitors continue to grow as a strategy for treating a wide range of neurological disorders that implicate excitotoxicity and neuroplasticity. Neuroprotection for acute ischemic stroke is achievable, and with continued improvements in our PSD-95 inhibitor technology, providing a benefit to patients in additional indications such as stroke recovery, traumatic brain injury and Alzheimer’s disease should be achievable as well.” NoNO Inc. is an Ontario biotechnology company whose focus is on developing therapeutic drugs in areas of unmet medical needs. Its drug pipeline includes therapeutic agents in various stages of development ranging from cellular and molecular discovery to human clinical trials. Its lead projects relate to diseases of the nervous system whose mechanisms involve the protein PSD-95, including stroke, traumatic brain injury and neuropathic pain. NoNO Inc.’s strategy is to inhibit key protein-protein interactions of PSD-95 that are involved selectively in cellular signals that cause cell damage, but without interfering with normal cell functions.
