Anavex Life Sciences Announces First Patient Dosed in Extension Study to its U.S. Phase 2 Clinical Trial of ANAVEX®2-73 in Patients for Rett Syndrome


NEW YORK – June 25, 2019

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 diseases including Alzheimer’s disease, Parkinson’s disease, Rett syndrome and other central nervous system (CNS) diseases, today announced that the first patient, who completed the Phase 2 clinical trial ANAVEX®2-73-RS-001 voluntarily moved into the extension study and was dosed in the extension study for the treatment of Rett syndrome.

The open label, 12 week extension study is designed to evaluate long term safety, tolerability, and the effect of ANAVEX®2-73 on Rett syndrome patients following the completion of the Phase 2 study.

Patients who are eligible to be enrolled in the extension study are those who have completed 7 weeks of treatment in the ANAVEX®2-73-RS-001 trial in the U.S.

All eligible patients will be treated with oral liquid ANAVEX®2-73 formulation given once daily for additional 12 weeks. The extension study might be further extended.

ANAVEX®2-73 has already received orphan drug designation from the FDA for the treatment of Rett syndrome.

“We are delighted to provide continuation of ANAVEX®2-73 treatment for Rett syndrome patients. This study is part of an Anavex Rett syndrome program including further studies of ANAVEX®2-73, among them an ongoing Phase 2 study overseas[1],” said Christopher U Missling, PhD, President and Chief Executive Officer of Anavex. “In addition to Rett syndrome, Anavex has ongoing clinical development programs for ANAVEX®2-73 for the treatment of Alzheimer’s disease[2] and Parkinson’s disease dementia[3].”

About Rett Syndrome

Rett syndrome is a rare, non-inherited genetic postnatal progressive neurodevelopmental disorder that occurs almost exclusively in girls and leads to severe impairments, affecting nearly every aspect of the child’s life: their ability to speak, walk, eat and even breathe easily. The hallmark of Rett syndrome is near constant repetitive hand movements while awake. It is characterized by normal early growth and development (6 to 18 months) followed by a slowing of development, loss of purposeful use of the hands, distinctive hand movements, slowed brain and head growth, problems with walking, seizures and intellectual disability. There is currently no cure for Rett syndrome and treatment of the disorder is symptomatic. Management of symptoms is done through a multidisciplinary approach utilizing medication for motor difficulties, breathing irregularities and control of seizures through anticonvulsant drugs. Rett syndrome is caused by mutations in the MECP2 gene and strikes all racial and ethnic groups and occurs worldwide in approximately one in every 10,000 to 15,000 live female births.

About ANAVEX®2-73

ANAVEX®2-73 activates the Sigma-1 receptor (S1R) protein, which serves as a molecular chaperone and functional modulator involved in restoring homeostasis. In a Phase 2a Alzheimer’s disease (AD) study, ANAVEX®2-73 has shown dose dependent improvement in exploratory endpoints of cognition (MMSE) and activities of daily living (ADCS-ADL). Full genomic analysis of ANAVEX®2-73 Phase 2a AD patients was performed. The ANAVEX®2-73 Phase 2 Rett syndrome study design includes genomic biomarkers identified in the ANAVEX®2-73 Phase 2a AD study. Studies of ANAVEX®2-73 in a mouse model with a MECP2-null mutation that causes neurological symptoms that mimic Rett syndrome, ANAXEX®2-73 was evaluated in automatic visual response and respiration tests in 7-month old mice, an age at which advanced pathology is evident. Vehicle-treated methyl-CpG binding protein 2 (MECP2) mice demonstrated fewer automatic visual responses than wild-type mice. Treatment with ANAVEX®2-73 for four weeks significantly increased the automatic visual response in the MECP2 Rett syndrome disease mouse (p<0.05). Additionally, chronic oral dosing daily for 6.5 weeks of ANAVEX®2-73 starting at ~5.5 weeks of age was conducted in the MECP2 HET Rett syndrome disease mouse model assessed the different aspects of muscular coordination, balance, motor learning and muscular strengths, some of the core deficits observed in Rett syndrome. Administration of ANAVEX®2-73 resulted in both significant and dose related improvements in an array of these behavioral paradigms in the MECP2 HET Rett syndrome disease model. These experiments were sponsored by

About Anavex Life Sciences Corp.

Anavex Life Sciences Corp. (Nasdaq: AVXL) is a publicly traded biopharmaceutical company dedicated to the development of differentiated therapeutics for the treatment of neurodegenerative and neurodevelopmental diseases 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, recently completed a successful Phase 2a clinical trial for Alzheimer’s disease. 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 preclinical 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 neuroinflammation and mitochondrial dysfunction.
