Blarcamesine

Data of Blarcamesine confirm upstream SIGMAR1 activation Presented as Late Breaking Oral Communications at Clinical Trials on Alzheimer’s Disease (CTAD) Conference 2024 Oral, once daily blarcamesine meaningfully slowed clinical decline for early Alzheimer's disease patients with good comparative safety profile and no associated neuroimaging adverse events NEW YORK, Oct. 31, 2024 (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, neurodevelopmental, and neuropsychiatric disorders including Alzheimer’s disease, Parkinson’s disease, Rett syndrome, schizophrenia, and other central nervous system (CNS) diseases, today presented new data from the Phase IIb/III study showing that blarcamesine (ANAVEX®2-73), once daily orally, demonstrates pre-specified clinical efficacy through upstream SIGMAR1 activation. Clinical data confirmed the mechanism of action (MoA) by pre-specified SIGMAR1 gene analysis in people with early Alzheimer's disease (AD). The data were presented by Marwan Noel Sabbagh, MD, Professor of Neurology at Barrow Neurological Institute and Chairman of the Anavex Scientific Advisory Board at the Clinical Trials on Alzheimer’s Disease (CTAD) conference, which is taking place October 29 - November 1, 2024, in Madrid, Spain. SIGMAR1 is an integral membrane protein which activates an upstream compensatory process: Blarcamesine induces autophagy through SIGMAR1 activation resulting in restoring cellular homeostasis. In Alzheimer's disease patients, mutations (variants) of genes have generally been identified as disease risk factors. Likewise, impaired SIGMAR1 function (gene mutation, variants) leads to potential suboptimal function. Hence, patients who carry the non-mutated, common SIGMAR1 wild type (WT)1 gene, are expected to have stronger beneficial response to blarcamesine than patients with a SIGMAR1 mutation (variant), who nevertheless also benefited from treatment.2 This was confirmed in the Phase IIb/III study analysis: Over 48 weeks, blarcamesine significantly slowed clinical progression by 36.3% in the primary endpoint ADAS-Cog13 [LS mean ADAS-Cog13 difference of -2.027; P=0.008] in the ITT analysis. This signal was even stronger in the pre-specified common SIGMAR1 wild type (WT) group with slowed clinical progression by 49.8% at 48 weeks in the active group vs. placebo, respectively [LS mean ADAS-Cog13 difference of -2.317; P=0.015]. Equal analysis with CDR-SB led to comparable consistent results. “These data are very exciting, particularly featuring blarcamesine’s novel upstream mechanism of action, enhancing autophagy through SIGMAR1 activation, a key clearance mechanism that removes protein aggregates and misfolded proteins across the Alzheimer's disease continuum,” said Juan Carlos Lopez-Talavera, MD, PhD, Head of Research and Development of Anavex. “The advantage of blarcamesine is that it is a small oral molecule that exerts clinical benefits on cognition and neurodegeneration and could be appealing because of its route of administration and good comparative safety profile. We are on track for regulatory submission of blarcamesine in Europe (EMA) in the current quarter 2024.” Overall, blarcamesine, a small molecule administered orally once daily, demonstrated clinically meaningful improvement over 48 weeks with primary endpoint ADAS-Cog13 score being larger than 2 points.3 This suggests superior numerical clinical efficacy compared to approved therapies while also slowing neurodegeneration in early AD patients. Blarcamesine’s safety profile indicates not requiring routine MRI monitoring, and given its differentiated mechanism of action, could represent a novel treatment that could be complementary or an alternative to anti-beta amyloid monoclonal antibody drugs. “Alzheimer’s disease is such a devastating disease that affects tens of millions worldwide. We believe, the clinically meaningful study results provide the potential for patients and their families to have a better and longer quality of life,” said Christopher U. Missling, PhD, President and Chief Executive Officer of Anavex. “We believe the scalable and convenient features of blarcamesine could reduce crucial barriers within the currently complex healthcare ecosystem for Alzheimer's disease and provide broader access to a diverse population with early Alzheimer's disease.” The presentation is available on the Investors section of the Company’s website at www.anavex.com.

Part A of the placebo-controlled Phase 2 study has been completed ANAVEX®3-71 demonstrates a dose-dependent pharmacodynamic effect on objective EEG biomarkers of schizophrenia Patients are currently being dosed in Part B of the Phase 2 study which will investigate a longer treatment duration Oct. 17, 2024 -- Anavex Life Sciences Corp. (“Anavex” or the “Company”) (Nasdaq: AVXL), a clinical-stage biopharmaceutical company developing differentiated therapeutics for the treatment of Alzheimer's disease, Parkinson's disease, schizophrenia, neurodevelopmental, neurodegenerative, and rare diseases, including Rett syndrome, and other central nervous system (CNS) diseases, today announced encouraging preliminary electroencephalography (EEG) biomarker results from the Part A of the ongoing placebo-controlled Phase 2 clinical study of ANAVEX®3-71 for the treatment of schizophrenia. Part A of the Phase 2 study ANAVEX®3-71-SZ-001 (NCT06245213), was a multiple ascending dose study in 16 participants treated with either oral placebo, oral ANAVEX®3-71 90 mg daily, or oral ANAVEX®3-71 180 mg daily for 10 days. Preliminary results demonstrated a dose-dependent effect of ANAVEX®3-71 on two key EEG biomarkers in patients with schizophrenia. Treatment with ANAVEX®3-71 compared to placebo resulted in improvements in 40 Hz Auditory Steady-State Response (ASSR) Inter Trial Coherence (ITC) and Resting State Alpha Power, both of which were increased. These effects were most pronounced in the higher dose group demonstrating a dose-dependent pharmacodynamic effect. These results provide evidence of CNS target engagement and potential therapeutic effects of ANAVEX®3-71 in schizophrenia. The observed changes reversed known EEG and ERP biomarker abnormalities associated with schizophrenia1. These EEG biomarkers correlate with positive, negative, and cognitive symptoms of schizophrenia. Individuals with schizophrenia typically have reduced neural synchrony as measured by 40 Hz ASSR ITC. Improvements in 40 Hz ASSR ITC indicate enhanced neural synchronization, potentially leading to reduced auditory hallucinations (positive symptom), improved executive function, and working memory (cognitive symptoms).2 Individuals with schizophrenia also typically have decreased resting state alpha power correlating with sensory and behavioral problems. Increases in Resting State Alpha Power reflect improvements in thalamocortical circuits and sensory gating, potentially resulting in reduced irritability and anxiety (negative symptoms).3 “We are pleased to see an initial effect of biomarkers changing in people with schizophrenia treated with our oral M1/SIGMAR1 therapy ANAVEX®3-71, which could eventually help patients address both positive, negative, and cognitive symptoms of schizophrenia,” said Christopher U Missling, PhD, President and Chief Executive Officer of Anavex. “The results are encouraging for further development of ANAVEX®3-71 for people with schizophrenia.” ANAVEX®3-71 was well tolerated, with no serious adverse events reported. 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. ANAVEX®3-71 has previously demonstrated long-lasting, pro-cognitive effects and behavioral improvements in animal models of neurodegenerative diseases4,5, an ability to prevent cognitive decline in animal models6,7, and has shown robust safety signals in healthy volunteers at single doses ranging from 5 to 200 mg once daily.8,9 Recent research into the genetic underpinnings of schizophrenia has revealed links between this psychiatric disorder and neurodegenerative disease, suggesting the disorders may share certain mechanisms.10 Oral ANAVEX®3-71, in addition to the M1 muscarinic receptor activity, the combined SIGMAR1 receptor activity might offer a novel mechanism of action that may address multiple symptom domains without the motor side effects associated with traditional antipsychotics. The currently ongoing Part B of the placebo-controlled Phase 2 study, which includes more participants and a longer treatment duration, will provide more comprehensive data on the efficacy and safety of ANAVEX®3-71 in schizophrenia. Anavex expects data from Part B of the placebo-controlled Phase 2 study in the first half of 2025. 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, 11 with an additional 50-60% experiencing only a partial improvement in symptoms or unacceptable side effects.12 Anavex Life Sciences Corp.
