Anavex Life Sciences Announces Publication of Foundational Data for ANAVEX®2-73 in FXS (Autism)

Results Highlight Reversal of Hyperactivity and Restoration of Associative Learning and Reduction of Anxiety, Phenotypes Associated with Fragile X Syndrome.

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) diseases, announced that preclinical data of ANAVEX®2-73 (blarcamesine) in Fragile X syndrome were published in the peer-reviewed journal, Scientific Reports.

Fragile X syndrome is the most common form of inherited intellectual disability and the most frequent single gene cause of autism spectrum disorder with an estimated population of approximately 62,500 in the US and 1,088,500 worldwide. At present, there is no approved treatment for Fragile X syndrome.

The study evaluated doses of ANAVEX®2-73 in a validated animal model for the disease, which resulted in the reversal of hyperactivity and restoration of associative learning as well as reduction in anxiety-like and perseverative behaviors. In addition to showing a good safety profile, ANAVEX®2-73 also restored pAkt and BDNF levels in the hippocampus, which are signaling pathways particularly affected in Fragile X syndrome.

“Testing novel drugs that can safely improve the symptoms of Fragile X syndrome is a high priority,” said Walter E. Kaufmann, M.D., Chief Medical Officer of Anavex and corresponding author of the paper. “The present findings support the viability of SIGMAR1 as a therapeutic target in Fragile X syndrome, and the clinical potential of ANAVEX®2-73 (blarcamesine) in Fragile X syndrome and other neurodevelopmental disorders.”

The study, “Effects of the Sigma-1 Receptor Agonist Blarcamesine in a Murine Model of Fragile X Syndrome: Neurobehavioral Phenotypes and Receptor Occupancy,” is the basis for a Phase 2/3 ANAVEX®2-73 study in Fragile X syndrome. The fact that the investigation involved chronic administration, as opposed to acute dosing, provides additional evidence in favor of the clinical use of ANAVEX®2-73. Since the behavioral paradigms reflect the involvement of multiple cortical and subcortical regions, their marked improvement by ANAVEX®2-73 suggest widespread activation of SIGMAR1 by the drug and modulation of multiple neural pathways. Indeed, the observation of normalization of pAkt and BDNF levels after ANAVEX®2-73 administration, in a brain region critical for cognition and behavior, is also a finding with important implications for Fragile X syndrome and other similar disorders.

The study was supported by the FRAXA Research Foundation.
