Anavex Life Sciences Announces Grant of U.S. Patent Covering Blarcamesine (ANAVEX®2-73) for Treatment of Neurodevelopmental Disorders

Grant of Its Newest U.S. Patent Expands Anavex’s Intellectual Property Portfolio in Neurologic Indications

NEW YORK – January 8, 2024

Anavex Life Sciences Corp. (“Anavex” or the “Company”) (Nasdaq: AVXL), a clinical-stage biopharmaceutical company developing differentiated therapeutics for the treatment of neurodegenerative and neurodevelopmental disorders including Alzheimer’s disease, Parkinson’s disease, Rett syndrome and other central nervous system (CNS) disorders, announced today it was granted new U.S. Patent No. 11,839,600 entitled “NEURODEVELOPMENTAL DISORDER THERAPY” from the United States Patent and Trademark Office (USPTO) for its patent application number 17/890,083. Anavex’s newest patent expands coverage of ANAVEX®2-73 (blarcamesine) therapy to ameliorate various conditions associated with loss-of-function mutations of the gene encoding methyl-CpG binding protein (MeCP2).


The patent claims protect use of ANAVEX®2-73 (blarcamesine) to address a range of symptoms exhibited by patients suffering from neurodevelopmental and neurological conditions related to McCP2, such as abnormal breathing, abnormal cardiac function, abnormal feeding, abnormal choking, weight gain failure, abnormal sleep, seizures, abnormal gadolinium-enhancing lesions. Such conditions are frequently associated with diseases such as Rett syndrome, autism spectrum disorder, multiple sclerosis, cerebral palsy, Angelman syndrome, Williams syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS), childhood disintegrative disorder, Smith-Magenis syndrome, non-syndromic mental retardation, idiopathic neonatal encephalopathy, and idiopathic cerebral palsy. This newest patent is expected to remain in force at least until January 2037, not including any patent term extension.


“This new patent on use of ANAVEX®2-73 (blarcamesine) in ameliorating difficult symptoms associated with loss-of-function gene mutations of MeCP2 will be important for Anavex, further reinforcing our already strong position providing novel and effective therapies for debilitating neurodevelopmental and neurological diseases,” said Christopher U. Missling, PhD, President and Chief Executive Officer of Anavex. He further added “We are pleased with the continued development of the patent portfolio for ANAVEX®2-73 (blarcamesine). The grant of this new patent to Anavex further demonstrates our strong overall commitment to protecting the innovation and commercial opportunity of our product portfolio.”

About Neurodevelopmental Disorders

Neurodevelopmental disorders refer to a group of conditions that affect the way the brain and nervous system develop. These disorders can cause changes to thinking, feeling, language, and physical abilities like movement and coordination. Neurodevelopmental conditions typically start before adulthood and may continue into adulthood. They are often associated with social impairments and difficulties in communication. [1] The number of people globally with developmental intellectual disability was estimated at 107.62 million according to IHME, Global Burden of Disease (2019). [2]

About Anavex Life Sciences Corp.

Anavex Life Sciences Corp. (Nasdaq: AVXL) is a publicly traded biopharmaceutical company dedicated to the development of novel therapeutics for the treatment of neurodegenerative and neurodevelopmental disorders, including Alzheimer's disease, Parkinson's disease, Rett syndrome, and other central nervous system (CNS) diseases, pain, and various types of cancer. Anavex's lead drug candidate, ANAVEX®2-73 (blarcamesine), has successfully completed a Phase 2a and a Phase 2b/3 clinical trial for Alzheimer's disease, a Phase 2 proof-of-concept study in Parkinson's disease dementia, and both a Phase 2 and a Phase 3 study in adult patients with Rett syndrome. ANAVEX®2-73 is an orally available drug candidate that restores cellular homeostasis by targeting sigma-1 and muscarinic receptors. Preclinical studies demonstrated its potential to halt and/or reverse the course of Alzheimer's disease. ANAVEX®2-73 also exhibited anticonvulsant, anti-amnesic, neuroprotective, and anti-depressant properties in animal models, indicating its potential to treat additional CNS disorders, including epilepsy. The Michael J. Fox Foundation for Parkinson's Research previously awarded Anavex a research grant, which fully funded a preclinical study to develop ANAVEX®2-73 for the treatment of Parkinson's disease. ANAVEX®3-71, which targets sigma-1 and M1 muscarinic receptors, is a promising clinical stage drug candidate demonstrating disease-modifying activity against the major hallmarks of Alzheimer's disease in transgenic (3xTg-AD) mice, including cognitive deficits, amyloid, and tau pathologies. In preclinical trials, ANAVEX®3-71 has shown beneficial effects on mitochondrial dysfunction and neuroinflammation.
