Data Review by the Independent DSMB reported for Phase 2b/3 Trial of ANAVEX®2-73 for AD

Anavex Life Sciences Reports Data Review by the Independent Data Safety Monitoring Board for its Phase 2b/3 Clinical Trial of ANAVEX®2-73 in Patients with Alzheimer’s Disease

The Company anticipates topline data in the second half of 2022

NEW YORK – October 13, 2021

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, today announced that the Independent Data Safety Monitoring Board (DSMB) for the Company's Phase 2b/3 Alzheimer’s disease study of its investigational compound ANAVEX®2-73 (blarcamesine) has completed its recent pre-planned review of the preliminary Phase 2b/3 study data.

As specified in the protocol, the DSMB reviewed the interim safety data for the ANAVEX®2-73 Phase 2b/3 Alzheimer’s disease clinical study ANAVEX®2-73-AD-004 and its Open Label Extension (OLE) ANAVEX®2-73-AD-EP-004 ATTENTION-AD study.

Upon review of the interim safety data, the DSMB made the following recommendation:

  • The DSMB recommendation is to continue the studies without modification.

DSMBs are committees commonly used in clinical trials to protect the interests of the patients and the integrity of the study data in ongoing trials.

ANAVEX®2-73 activates the sigma-1 receptor (SIGMAR1). Data suggests that activation of SIGMAR1 results in the restoration of complete housekeeping function within the body and is pivotal to restoring neural cell homeostasis and promoting neuroplasticity.[1]

PET scan data previously confirmed dose-dependent target engagement of SIGMAR1 with ANAVEX®2-73.[2]

The placebo-controlled 509-patient Phase 2b/3 ANAVEX®2-73 clinical study in patients with Alzheimer's diseaseachieved full enrollment and includes prespecified SIGMAR1 gene expression as endpoints using ADAS-Cog (cognition) and ADCS-ADL (activities of daily living and function) as primary endpoints.[3] The Company anticipates topline data in the second half of 2022.

Anavex Life Sciences’ product portfolio includes small drug molecule lead candidate ANAVEX®2-73 for the treatment of Alzheimer’s disease, Parkinson’s disease and Rett syndrome.

About ANAVEX®2-73-AD-004 Clinical Study ( Identifier: NCT03790709) and OLE ANAVEX®2-73-AD-EP-004 Clinical Study ATTENTION-AD ( Identifier: NCT04314934)

ANAVEX®2-73-AD-004 clinical study is a Phase 2b/3 double-blind, randomized, placebo-controlled, 48-week safety and efficacy trial of ANAVEX®2-73 for the treatment of early Alzheimer’s disease. The Phase 2b/3 study enrolled 509 patients, randomized 1:1:1 to two different ANAVEX®2-73 doses or placebo. The ANAVEX®2-73 Phase 2b/3 study design includes genomic precision medicine biomarkers identified in the previous ANAVEX®2-73 Phase 2a study (ANAVEX2-73-002, NCT02244541). Primary and secondary endpoints will assess safety and both cognitive and functional efficacy, measured through ADAS-Cog, ADCS-ADL and CDR-SB. ANAVEX®2-73 Phase 2a Alzheimer’s disease study previously demonstrated dose dependent improvement in exploratory endpoints of cognition (MMSE) and function (ADCS-ADL).[4] ANAVEX®2-73-AD-EP-004 is the 96-week open label extension of the placebo-controlled Phase 2b/3 ANAVEX®2-73 study.

About Alzheimer’s Disease

Alzheimer’s disease is a progressive degenerative brain disorder that gradually destroys a person's memory and ability to learn, reason, make judgments, communicate and carry out daily activities. An estimated 5.7 million Americans have currently Alzheimer's dementia. Alzheimer’s is the most common cause of dementia among older adults and is estimated to rank as the third leading cause of death for older people in the United States, just behind heart disease and cancer. In 2020, Alzheimer's and other dementias cost the nation $305 billion. By 2050, these costs could rise as high as $1.1 trillion.[5] There are currently over 50 million people living with dementia around the world, with numbers expected to increase to nearly 152 million by 2050.[6] Almost 10 million new cases of dementia are diagnosed each year worldwide, implying one new case every 3 seconds, and a significant increase in the caregiving burden placed on society and families.[7]

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), successfully completed a Phase 2a clinical trial for Alzheimer’s disease and recently a Phase 2 proof-of-concept study in Parkinson’s disease dementia and a Phase 2 study in adult patients with Rett syndrome. 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 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.
