Nerinetide

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.
