NEW YORK, June 16, 2020 (GLOBE NEWSWIRE) -- 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, today announced that it has surpassed by
ANAVEX®2-73 (blarcamesine) is an orally available, small-molecule activator of the sigma-1 receptor which, data suggest, is pivotal to restoring neural cell homeostasis and promoting neuroplasticity.1
The multi-center, double-blind clinical trial at 8 sites across U.S. is measuring safety, tolerability, and efficacy of daily oral ANAVEX®2-73 (blarcamesine) doses or placebo. After completing the trial, eligible participants are able to join a voluntary open-label extension study of ANAVEX®2-73 (blarcamesine).
Anavex previously reported interim data of the PART A intensive PK sub-cohort in the first 6 patients of the U.S. Phase 2 Rett syndrome study in which ANAVEX®2-73 (blarcamesine) demonstrated significant improvements of the two global efficacy endpoints, the Rett Syndrome Behaviour Questionnaire (RSBQ) Total score and the Clinical Global Impression – Improvement (CGI-I). ANAVEX®2-73 (blarcamesine) also significantly improved the RSBQ Hand Behaviours and the RSBQ Breathing Abnormalities. In addition, efficacy signals on both caregiver- and clinician-based measures of severity correlated with levels of glutamate, a key biomarker of disease pathogenesis.
This study is one of three ongoing clinical studies in Anavex’s Rett Syndrome Program: U.S. RTT (ANAVEX®2-73-RS-001)2, AVATAR (ANAVEX®2-73-RS-002)3 and EXCELLENCE (ANAVEX®2-73-RS-003)4. ANAVEX®2-73 (blarcamesine) had previously received Fast Track designation, Rare Pediatric Disease designation and Orphan Drug designation from the FDA for the treatment of Rett syndrome.
“Since there is currently no approved agent to treat this devastating disease, there is a significant unmet medical need for patients with Rett syndrome,” said Christopher U. Missling, PhD, President and Chief Executive Officer of Anavex. "We are excited to complete enrollment in this carefully conducted, multicenter study with ANAVEX®2-73 (blarcamesine) in Rett syndrome and look forward to reporting the results later this year."
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 (blarcamesine)
ANAVEX®2-73 (blarcamesine) 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 showed dose dependent improvement in exploratory endpoints of cognition (MMSE) and activities of daily living (ADCS-ADL). The ANAVEX®2-73 Phase 2 Rett syndrome study design includes genomic biomarkers of response identified in the ANAVEX®2-73 Phase 2a AD study. Studies of ANAVEX®2-73 (blarcamesine) in a mouse model of Rett syndrome, carrying a heterozygous Mecp2-null mutation and presenting with neurological impairments that mimic the human disorder, demonstrated improvements at both young ages (~6 weeks) and adulthood (7 months). Chronic oral administration of ANAXEX®2-73 (blarcamesine) led to significant improvements in multiple motor, sensory, and autonomic phenotypes of relevance to Rett syndrome, including motor coordination and balance, acoustic and visual responses, hindlimb clasping (resembling the characteristic hand stereotypies), and episodes of apnea. Notably, these changes were dose related and also evident in animals at an advanced stage of pathology. These experiments were sponsored by Rettsyndrome.org.
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 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), recently completed a successful Phase 2a clinical trial for Alzheimer’s disease. ANAVEX®2-73 (blarcamesine) 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 (blarcamesine) 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 (blarcamesine) for the treatment of Parkinson’s disease. ANAVEX®3-71, which targets sigma-1 and 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 mitochondrial dysfunction and neuroinflammation.
