(Nasdaq: NRXP), today announced the award of a European Patent (EP 3 570 878 B1) entitled “Anti HERV K Envelope Antibody and Uses Thereof.” The patent, together with two previously-issued US patents (10,723,787 and 10,981,977) describes in detail the discovery that the envelope protein (K Env) of Human Endogenous Retrovirus K (HERV K) is found in the spinal fluid of more than 75% of people with Amyotrophic Lateral Sclerosis (ALS), is shown to be highly neurotoxic, and to produce the neurodegenerative findings of ALS in laboratory animals and in human motor neuron cell culture. HERVs are the remnants of viruses that infected primates between 2 and 5 million years ago and are now thought to have played a role in human disease. A monoclonal antibody against K Env (GNK-301) has been shown to block those neurotoxic effects in the same models. The discovery was made by a team comprised of scientists from Geneuro SA (Lyon, France) and the US National Institute of Neurological Disorders and Stroke (NINDS) of the US National Institutes of Health (NIH) under a Cooperative Research and Development Agreement (CRADA) and subsequent patent agreement. The patents are jointly owned by GeNeuro and the US Dept. of Health and Human Services. The assets of the former Geneuro SA were awarded to GeNeuro, Inc. (Miami, FL) by the Courts of Switzerland in June 2026 and GeNeuro initiated manufacture of GNK-301 under Good Manufacturing Practices (cGMP) with the plan to initiate human Phase 1 trials of GNK-301 in the US and Europe in the latter half of 2027. Geneuro SA previously conducted five human trials of a related antibody (Temelimab®) which targets the envelope protein of HERV W in more than 400 human participants who had Multiple Sclerosis, Type 1 Diabetes, or symptoms of Long Covid, with no Serious Adverse Events. Temelimab was shown to cross the blood brain barrier and to achieve a statistically significant reduction in neurodegeneration, as measured by “Black Holes” on Magnetic Resonance Imaging (MRI) and a corresponding reduction in brain shrinkage. The Company believes these results support the potential for anti-HERV Envelope antibodies to achieve clinically meaningful effects in patients with HERV-mediated neurodegenerative diseases. The recently-issued patent adds to a portfolio of more than 25 issued and pending patents owned by GeNeuro related to the effects of HERVs and to methods of diagnosing and mitigating those effects.

In August 2026, GeNeuro, in partnership with NINDS was selected in the first round of the ALS grant competition of the Congressionally Directed Medical Research Program (CDMRP) for potential awards in Therapeutic Development and Biomarker Development and is currently preparing its final bid submission. This weekend, the first annual conference on “HERVs and Humanity” will be held at the Princeton Institute for Advanced Study to bring together an international group of clinicians and molecular biologists to prioritize research objectives and clinical priorities in this dramatic new area of science. Portions of the conference will be simulcast. “ALS is possibly the most devastating diseases one can contract, with a life expectancy of two to five years. The opportunity to partner with the NIH and leading experts across the globe around a biomarker-targeted, potentially disease-modifying drug has the potential to forever change the course of this terrible disease,” said Dr. Jonathan Javitt, the Company’s CEO. About GeNeuro, Inc. GeNeuro, Inc. (www.geneuro.us) is a newly-formed US Company organized around the assets of the former Geneuro SA. Those assets include the products of more than $180 million in funded research on Human Endogenous Retrovirus-targeted drugs for ALS, Multiple Sclerosis, Type 1 Diabetes, and Schizophrenia. Temelimab, targeting the HERV W Envelope protein has reached Phase 2 in Europe with completed clinical trials demonstrating statistically-significant reductions in neurodegeneration in multiple sclerosis and decreased Islet cell destruction in Type 1 diabetes. GNK-301, targeting ALS was developed and patented worldwide under a Cooperative Research and Development Agreement with the US National Institutes of Health and is now in production and anticipated to enter Phase 1 human trials in the second half of 2026.
