Anavex Life Sciences Reports Publication of ANAVEX®3-71 in Clinical Journal Confirming Pharmacokinetic Dose Proportionality of ANAVEX® 3-71 in Humans

NEW YORK – January 24, 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, today announced a peer-reviewed publication in Clinical Pharmacology in Drug Development, findings from the ANAVEX®3-71 first-in-human study which achieved its safety objectives. The publication is entitled, ‘Population-Based Characterization of the Pharmacokinetics and Food Effect of ANAVEX3-71, a Novel Sigma-1 Receptor and Allosteric M1 Muscarinic Receptor Agonist in Development for Treatment of Frontotemporal Dementia, Schizophrenia, and Alzheimer Disease’.[1] The publication reports the Population-based characterization of the Pharmacokinetics (PK) and food effect of ANAVEX®3-71 as part of the single ascending dose study in healthy participants with the primary objective of assessing dose proportionality of ANAVEX®3-71, and to characterize the effect of food on the PK of ANAVEX®3-71.


The results from this PK evaluation demonstrated that ANAVEX®3-71, at single ascending doses of 5 to 200 mg, is linear, dose proportional, and time invariant. Food had no effect on the PK of ANAVEX®3-71. This data also expands the safety objectives met in this first-in-human study of ANAVEX®3-71, further supporting its drug development program.


While KarXT from Karuna Therapeutics (KRTX), a muscarinic M1 receptor agonist, demonstrated weak benefits on cognitive impairments in individuals with Schizophrenia,[2] ANAVEX®3-71’s dual-pharmacological action on SIGMAR1 and M1 muscarinic receptors is implicated in its pro-cognitive effects in murine Alzheimer’s disease models and demonstrates its potential to treat cognitive and behavioral deficits in neurological diseases by affecting protein homeostasis in the central nervous system.[3],[4],[5]

“This published clinical study demonstrates Anavex’s commitment to advance Anavex’s clinical pipeline including ANAVEX®3-71 for Schizophrenia, Frontotemporal Dementia, and Alzheimer's Disease,” said Christopher U Missling, PhD, President and Chief Executive Officer of Anavex. "We are looking forward to reporting first patient dosed in the upcoming U.S. Phase 2 clinical trial in Schizophrenia with ANAVEX®3-71.”

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, schizophrenia 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 recently 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 SIGMAR1 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 SIGMAR1 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.
