Study ANAVEX3-71-SZ-001 successfully completes enrollment with a total of 71 participants Both Part A (16 participants) and Part B (55 participants) of the placebo-controlled Phase 2 study fully enrolled Top line data expected in the second half of 2025 NEW YORK, May 01, 2025 (GLOBE NEWSWIRE) -- Anavex Life Sciences Corp. ("Anavex" or the "Company") (Nasdaq: AVXL), a clinical-stage biopharmaceutical company focused on developing innovative treatments for Alzheimer's disease, Parkinson's disease, schizophrenia, neurodevelopmental, neurodegenerative, and rare diseases, including Rett syndrome, and other central nervous system (CNS) disorders, today announced the successful completion of enrollment in its Phase 2 clinical study of ANAVEX®3-71 for the treatment of schizophrenia (ANAVEX3-71-SZ-001, NCT06245213). The study has enrolled a total of 71 participants, with 16 participants in Part A and 55 participants in Part B. Part A of the study, which investigated multiple ascending doses, has been completed with encouraging preliminary safety and electroencephalography (EEG) biomarker results previously reported. Part B, which includes more participants and a longer treatment duration, will provide more comprehensive clinical and biomarker data on the efficacy and safety of ANAVEX®3-71 in individuals with schizophrenia. “We are pleased to announce the full enrollment of our ANAVEX3-71-SZ-001 study and would like to thank all the patients and investigators for their participation in this first clinical efficacy trial of ANAVEX®3-71,” said Christopher U Missling, PhD, President and Chief Executive Officer of Anavex. “There is a substantial unmet medical need for a drug that can effectively address all symptoms of schizophrenia, and we are hopeful that these results are encouraging for further development of ANAVEX®3-71 for people with schizophrenia.” Oral ANAVEX®3-71 is a dual SIGMAR1 receptor agonist and M1 positive allosteric modulator with agonistic effects. This novel mechanism of action offers the potential to treat all symptom domains of schizophrenia without the side effects of standard of care antipsychotics. The Company expects to report top-line data from the study in the second half of 2025. This release discusses investigational uses of an agent in development and is not intended to convey conclusions about efficacy or safety. There is no guarantee that any investigational uses of such product will successfully complete clinical development or gain health authority approval. About Schizophrenia Schizophrenia is a persistent and often disabling mental illness impacting how a person thinks, feels, and behaves, and affects nearly 24 million people worldwide, including 2.8 million people in the U.S. It is characterized by three symptom domains: positive symptoms (hallucinations and delusions), negative symptoms (difficulty enjoying life and withdrawal from others), and cognitive impairment (deficits in memory, concentration, and decision-making). In part due to limitations with current treatments, people living with schizophrenia often struggle to maintain employment, live independently, and manage relationships. While current treatments can be effective in managing select symptoms, approximately 34% of people do not respond to therapy, 1 with an additional 50-60% experiencing only a partial improvement in symptoms or unacceptable side effects.2 About Anavex Life Sciences Corp.

NEW YORK and TRUMBULL, Conn., April 30, 2025 /PRNewswire/ -- Apertura Gene Therapy, a biotechnology company focused on innovative gene therapy solutions, and the Rett Syndrome Research Trust (RSRT), an organization working to cure Rett Syndrome, today announced a collaboration to license Apertura's human transferrin receptor 1 capsid (TfR1 CapX). This partnership aims to advance innovative genetic medicine approaches for the treatment of Rett Syndrome, a rare genetic neurological disorder caused by random mutations in the MECP2 gene on the X chromosome that primarily affect females, causing developmental regression and severe motor and language impairments. Apertura's TfR1 CapX is an intravenously delivered adeno-associated virus (AAV) capsid engineered to bind the transferrin receptor 1(TfR1), enabling efficient delivery of genetic medicines across the blood-brain barrier (BBB). TfR1 is a well-characterized BBB-crossing receptor, broadly and consistently expressed throughout life—even in the context of neurological disease—making it an attractive target for CNS delivery in disorders like Rett syndrome. Developed by Apertura's academic founder, Dr. Ben Deverman, Director of Vector Engineering at the Broad Institute, TfR1 CapX has shown strong CNS selectivity in preclinical studies, achieving over 50% neuronal and 90% astrocyte transduction across multiple brain regions. Because Rett syndrome affects the brain diffusely, broader cellular transduction may correlate with greater symptomatic improvement. "Efficient, safe, and widespread delivery of genetic medicines to the brain is the ultimate goal for treating CNS disorders such as Rett syndrome. Successfully addressing this challenge would dramatically accelerate the development of genetic medicines for Rett and other neurological diseases. My colleagues and I have extensively evaluated advanced delivery technologies, and Apertura's capsid stands out for its impressive CNS biodistribution capabilities," said Monica Coenraads, Founder and CEO of RSRT and parent to an adult daughter with Rett. "We're enthusiastic about integrating this innovative capsid into our internal gene-editing programs and facilitating its adoption for external Rett syndrome programs as well. This collaboration represents a major step forward for patients." Last year RSRT launched the MECP2 Editing Consortium, a collaboration among six labs, developing next-generation genetic medicines for Rett syndrome. The Consortium's editing programs will be utilizing the Apertura capsid to deliver genetic medicine cargoes diffusely across the brain non-invasively. Furthermore, the license allows RSRT to sublicense the capsid for Rett programs. "RSRT has made remarkable progress in advancing Rett syndrome therapies, and Apertura is committed to accelerating this momentum with TfR1 CapX. Our engineered capsid addresses the critical need for more potent and less invasive treatments, significantly benefiting patients and caregivers. This collaboration reflects the innovative efforts of both organizations and serves as a pioneering example of how industry partnerships can rapidly advance vital therapies for patients in need," said Diego Garzón, PhD, Vice President of Corporate Development, Apertura Gene Therapy. "Apertura's TfR1 capsid has the potential to transform treatments for CNS diseases. We are committed to partnering with both for-profit and non-profit organizations to maximize this innovation's impact for patients." About Rett Syndrome Rett syndrome is a rare genetic neurodevelopmental disorder caused by random mutations in the MECP2 gene on the X chromosome. The disorder predominantly affects girls but can also rarely affect boys. Symptoms typically become apparent between the ages of 12 to 18 months. Rett syndrome is devastating as it deprives toddlers of speech, hand use, and normal movement often including the ability to walk. As childhood progresses the disorder brings anxiety, seizures, tremors, breathing difficulties, and severe gastrointestinal issues. While their bodies suffer, it is believed that their cognitive abilities remain largely intact. Although most children survive to adulthood, they require total round- the-clock care. About Rett Syndrome Research Trust The Rett Syndrome Research Trust is a non-profit organization exclusively focused on advancing genetic medicines for Rett syndrome. Multiple clinical trials in gene therapy for Rett syndrome are now underway, all possible because of RSRT-funded research. In 2024 RSRT launched a $40 million initiative, Roadmap to Cures, with a goal to bring three genetic medicines, beyond the current gene therapies, to clinical trials by 2028. RSRT's mission is clear, urgent, and personal: to cure Rett syndrome and transform the lives of the people we love. To learn more, please visit . Follow us on Facebook, Instagram and YouTube.
